To study student and staff views of the role and use of handouts, note-taking and overhead transparencies in veterinary science lectures at the University of Queensland The Nominal Group Technique was used to help develop a questionnaire, which was completed by 351 students (a response rate of 84%) and 35 staff (76%) from the 5 years of the veterinary course. The data were analysed using the SAS statistical computer package. Staff and students held different views as to the frequency with which handouts should be used, their educational value, and whether they should be complete or partial. Fewer students than staff agreed that handouts discourage further reading in a subject. Almost all staff and students saw the central functions of note-taking to be provision of notes for subsequent revision and encoding information given by the lecturer. More students than staff however, considered that note-taking in lectures interferes with understanding. Staff and students held similar views as to the uses of overheads in lectures. Interestingly however, more staff than students agreed that overheads often contain too much information. Both students and staff saw the central role of note-taking as providing a set of good notes for revision. Generally students preferred that this information be provided in the form of partial or complete handouts, while staff preferred students to take notes and to read outside lectures. Surprisingly, more staff than students felt that overhead transparencies often contained too much information. Note-taking, handouts and overhead transparencies need to be linked in a coherent educational strategy to promote effective learning.

For middle school students with learning disabilities (LD), one major component of learning in content area classes, such as science, involves listening to lectures and recording notes. Lecture learning and note-taking are critical skills for students to succeed in these classes. Despite the importance of note-taking skills, no research has been reported on the problems that school-age students with LD encounter when recording notes during science lectures. Using a sample size of 90 middle school students, the performance of students with LD was compared to students with no learning disabilities (NLD). Results found that students with LD performed significantly worse than students with NLD in terms of the type and amount of notes recorded and test performance.

Lecture-Capture Software and the Teaching of Soils

NASA Astrophysics Data System (ADS)

Brevik, Eric C.

2014-05-01

Several companies now offer software that can record academic lectures and place them on password-protected course websites for future review by students. Using lecture-capture software offers several advantages for the instructor and the students, including: 1) The ability for students who miss class for legitimate reasons (e.g., participation in school-sanctioned extra-curricular activities, illness or family emergencies) to get lecture materials by logging into the class website. This provides these students with a more complete exposure to the material than simply copying a classmate's notes. 2) The instructor is able to direct students who miss class for legitimate reasons to the recorded lecture rather than needing to spend time going over the material with those students and that recap does not end up being rushed. 3) The ability to address course conflicts for graduating seniors by allowing them to take the lecture portion of the class via recorded lecture. 4) Students who desire more in-depth learning are able to go back to selected portions of previous lectures to review and reconsider a topic of discussion or to fill in vague sections of their notes. There are also potential disadvantages to the use of lecture-capture software, including: 1) decreased student attendance in class because they feel they can watch class later at a time of their own choosing, 2) additional time spent by the instructor dealing with the technology, and 3) problems with hardware or software during class time that prevents recording a given day's lecture. These problems can often be addressed or justified relatively easily. If problem 1 is of concern to an instructor it can be addressed by blocking online access to individual students who have a poor record of class attendance. In the case of problem 2, the extra time spent with the technology is often offset by a reduction in time answering questions from students who have missed class. Problem 3 does happen, but in the author's experience it is fairly rare, representing less than 5% of class sessions per semester. Student comments have been overwhelmingly favorable towards the use of captured lectures since the technology was first adopted in the author's classes in 2009.

2017-11-01

A combined experimental-correlational study with a diverse sample (N = 182) from 2 research sites tested a set of 5 a priori hypotheses about mind wandering and learning, using a realistic video lecture on introductory statistics. Specifically, the study examined whether students' vulnerability to mind wandering during the lecture would predict learning from, and situational interest in, the video and also whether longhand note-taking would help reduce mind wandering, at least for some students. One half of the participants took notes during the video, and all were subsequently tested on lecture content without notes. Regression and mediation analyses indicated that (a) several individual-differences variables (e.g., pretest score, prior math interest, classroom media multitasking habits) uniquely predicted in-lecture mind wandering frequency; (b) although the note-taking manipulation did not reduce mind wandering at the group level, note-taking still reduced mind wandering for some individuals (i.e., those with lower prior knowledge and those who took notes of high quality and quantity); (c) mind wandering uniquely predicted both learning (posttest) and situational interest outcomes above and beyond all other individual-differences variables; (d) moreover, mind wandering significantly mediated the effects of several individual differences; and, finally, (e) not all types of mind wandering were problematic-in fact, off-task reflections about lecture-related topics positively predicted learning. These results, which were generally robust across the 2 sites, suggest that educationally focused cognitive research may benefit from considering attentional processes during learning as well as cognitive and noncognitive individual differences that affect attention and learning.

Digital assist: A comparison of two note-taking methods (traditional vs. digital pen) for students with emotional behavioral disorders

NASA Astrophysics Data System (ADS)

Rody, Carlotta A.

High school biology classes traditionally follow a lecture format to disseminate content and new terminology. With the inclusive practices of No Child Left Behind, the Common Core State Standards, and end-of-course exam requirement for high school diplomas, classes include a large range of achievement levels and abilities. Teachers assume, often incorrectly, that students come to class prepared to listen and take notes. In a standard diploma, high school biology class in a separate school for students with emotional and behavioral disorders, five students participated in a single-subject, alternating treatment design study that compared the use of regular pens and digital pens to take notes during 21 lecture sessions. Behavior measures were threefold between the two interventions: (a) quantity of notes taken per minute during lectures, (b) quantity of notes or notations taken during review pauses, and (c) percent of correct responses on the daily comprehension quizzes. The study's data indicated that two students were inclined to take more lecture notes when using the digital pen. Two students took more notes with the regular pen. One student demonstrated no difference in her performance with either pen type. Both female students took more notes per minute, on average, than the three males regardless of pen type. During the review pause, three of the five students only added notes or notations to their notes when using the regular pen. The remaining two students did not add to their notes. Quiz scores differed in favor of the regular pen. All five participants earned higher scores on quizzes given during regular pen sessions. However, the differences were minor, and recommendations are made for specific training in note-taking, the pause strategy, and digital pen fluency which may produce different results for both note-taking and quiz scores.

Flipped classroom model improves graduate student performance in cardiovascular, respiratory, and renal physiology.

PubMed

Tune, Johnathan D; Sturek, Michael; Basile, David P

2013-12-01

The purpose of this study was to assess the effectiveness of a traditional lecture-based curriculum versus a modified "flipped classroom" curriculum of cardiovascular, respiratory, and renal physiology delivered to first-year graduate students. Students in both courses were provided the same notes and recorded lectures. Students in the modified flipped classroom were required to watch the prerecorded lectures before class and then attend class, where they received a quiz or homework covering material in each lecture (valued at 25% of the final grade) followed by a question and answer/problem-solving period. In the traditional curriculum, attending lectures was optional and there were no quizzes. Evaluation of effectiveness and student performance was achieved by having students in both courses take the same multiple-choice exams. Within a comparable group of graduate students, participants in the flipped course scored significantly higher (P ≤ 0.05) on the cardiovascular, respiratory, and weighted cumulative sections by an average of >12 percentage points. Exam averages for students in the flipped course also tended to be higher on the renal section by ∼11 percentage points (P = 0.06). Based on our experience and responses obtained in blinded student surveys, we propose that the use of homework and in-class quizzes were critical motivating factors that likely contributed to the increase in student exam performance. Taken together, our findings support that the flipped classroom model is a highly effective means in which to disseminate key physiological concepts to graduate students.

Using Portfolios to Engage Introductory Geoscience Students in Their Subject and to Develop Learning Skills.

NASA Astrophysics Data System (ADS)

Boyle, A. P.; Prior, D. J.

2008-12-01

It is often difficult to deal with wide-ranging, exciting geoscience topics at introductory level when the background geoscience knowledge of the incoming students is limited. This means that new students can often be confronted by self-contained, subject-based topics (e.g. introductory mineralogy) and fail to see where the bigger pictures may be. Another issue, partly arising from massification and thus increasing diversity of student cohorts but also to changes in UK school education goals, is the realisation that incoming students have difficulties combining lecture note taking, reading and general organisation of paper-based materials into a learning package that can help them write structured essays. They need help with the transfer from school to university education. Two years ago, a curriculum review provided the opportunity to develop a new module that could address these issues. The module deals with current topics. Students attend a series of 8 lectures given by 8 different faculty staff covering topics like The Origin of the Moon, Earthquake Prediction, Mass Extinctions, Snowball Earth, and Geohazards spread over the introductory year. Each lecturer uses whatever delivery style they want (PowerPoint, chalk and talk), but the lecture must be an illustration of the scientific method dealing with evidence, models and uncertainty, and must direct students towards a range of associated reading. The students develop a portfolio with a section for each lecture topic. Each section contains their notes, annotated copies of the reading and a one page (A4) summary of the main points of the topic, derived from both the notes and reading. The students also develop a glossary of geological terms. In addition, the students must attend 6 extra talks given by guest speakers at either the student society meetings or the departmental seminar series. Assessment is by the portfolio (40%) and a final essay paper (60%). The portfolio is collected in at the end of the first semester and students are given formative feedback that includes an indicative mark not used for summative purposes. The portfolio is collected again before the end of the second semester so that it can be summatively assessed and returned to facilitate revision. Students who receive formative feedback at the end of the first semester typically improve their second semester performance as a result. A significant number of students, in both years this module has run, do not submit their portfolio for formative assessment and it is notable that their second semester performance is not as good. The final essay paper requires one essay to be answered in 60minutes from a choice of two, which themselves are selected from four essay titles given to the students 6 weeks before the examination. Students are informed that their essays must cover lecture material and reading; a key marking descriptor for a good grade at UK universities is 'shows evidence of reading beyond lecture notes'. Student assessment performance has been good and their feedback on the module has positive. Some are clearly transferring their portfolio skills into other modules. The requirement that students attend six extra talks has improved attendances at invited speaker sessions, especially for the student society, but has also had an affective effect by providing the spur for new students to engage more fully with the life of the department and to get stuck into some often challenging geology.

Deaf/hard-of-hearing and other postsecondary learners' retention of STEM content with tablet computer-based notes.

Stinson, Michael S; Elliot, Lisa B; Easton, Donna

2014-04-01

Four groups of postsecondary students, 25 who were deaf/hard of hearing (D/HH), 25 with a learning disability, 25 who were English language learners (ELLs), and 25 without an identified disability studied notes that included text and graphical information based on a physics or a marine biology lecture. The latter 3 groups were normally hearing. All groups had higher scores on post- than on pretests for each lecture, with each group showing generally similar gains in amount of material learned from the pretest to the posttest. For each lecture, the D/HH students scored lower on the pre- and posttests than the other 3 groups of participants. Results indicated that students acquired measurable amounts of information from studying these types of notes for relatively short periods and that the notes have equal potential to support the acquisition of information by each of these groups of students.

Using Guided Notes to Increase the Understanding of Anatomy and Physiology in 11th Grade Science Students

NASA Astrophysics Data System (ADS)

Mariano, Jay

A survey of over 500 science teachers reported that two thirds of their science classes were lecture based lessons where students were required to listen and take notes (Boyle, 2010). In addition to taking notes from lectures, note taking is a necessary skill to possess to record scientific observations and procedures and record information during class. Guided notes is a pedagogical method in which the instructor prepares and provides students with a modified form of lecture information to guide students (Neef, McCord, & Ferreri, 2006). This study examined the extent to which the use of guided notes in a unit of study of the muscular system of anatomy and physiology positively affected the mastery on content-based assessments for 11 th grade students. The data collection methods included quiz and test scores, a 4-point Likert scale survey, and an open-ended questionnaire. Results of the data revealed that guided notes was one factor that led to mastery in learning content. Additionally, students in this study preferred this method as it helped them to distinguish relevant information allowing more time to listen and focus on the teacher.

Traditional lecture versus jigsaw learning method for teaching Medication Therapy Management (MTM) core elements.

PubMed

Wilson, Jennifer A; Pegram, Angela H; Battise, Dawn M; Robinson, April M

2017-11-01

To determine if traditional didactic lecture or the jigsaw learning method is more effective to teach the medication therapy management (MTM) core elements in a first year pharmacy course. Traditional didactic lecture and a pre-class reading assignment were used in the fall semester cohort, and the jigsaw method was used in the spring semester cohort. Jigsaw is a cooperative learning strategy requiring students to assume responsibility for learning, and subsequently teaching peers. The students were responsible for reading specific sections of the pre-class reading, and then teaching other students in small groups about their specific reading assignments. To assess potential differences, identical pre- and post-tests were administered before and after the MTM section. Additionally, grade performance on an in-class project and final exam questions were compared, and students were surveyed on perceptions of teaching method used. A total of 45 and 43 students completed both the pre- and post-test in the fall and spring (96% and 93% response rate), respectively. Improvement in post-test scores favored the traditional method (p = 0.001). No statistical differences were noted between groups with grade performance on the in-class project and final exam questions. However, students favored the jigsaw method over traditional lecture and perceived improvements in problem solving skills, listening/communication skills and encouragement of cooperative learning (p = 0.018, 0.025 and 0.031). Although students favored the jigsaw learning method, traditional didactic lecture was more effective for the pre- and post-knowledge test performance. This may indicate that traditional didactic lecture is more effective for more foundational content. Copyright © 2017 Elsevier Inc. All rights reserved.

Tanamatayarat, J.; Sujarittham, T.; Wuttiprom, S.; Hefer, E.

2017-09-01

In higher education, lecturing has been found to be the most prevalent teaching format for large classes. Generally, this format tends not to result in effective learning outcomes. Therefore, to support student learning in these large lecture classes, we developed guided notes containing quotations, blank spaces, pictures, and problems. A guided note taking strategy was selected and has been used in our introductory physics course for many years. In this study, we investigated the results of implementing the guided note taking strategy to promote student learning on electrostatics. The samples were three groups of first-year students from two universities: 163 and 224 science students and 147 engineering students. All of the students were enrolled in the introductory physics course in the second semester. To assess the students’ understanding, we administered pre- and post-tests to the students by using the electrostatics test. The questions were selected from the conceptual survey of electricity and magnetism (CSEM) and some leading physics textbooks. The results of the students’ understanding were analyzed by the average normalized gains (). The value of each group was 0.61, 0.55, and 0.54, respectively. Furthermore, the students’ views on learning with the guided note taking strategy were explored by using the five-point rating scale survey. Most students perceived that the strategy helped support their active learning and engagement in the lectures.

These notes are a short summary of a set of lectures given within the frame of the "Critical Stability of Quantum Few-Body Systems" International School held in the Max Planck Institute for the Physics of Complex Systems (Dresden). The main goal of the lectures has been to provide the basic ingredients for the description of few-body systems in coordinate space. The hyperspherical harmonic and the adiabatic expansion methods are introduced in detail, and subsequently used to describe bound and continuum states. The expressions for the cross sections and reaction rates for three-body processes are derived. The case of resonant scattering and the complex scaling method as a tool to obtain the resonance energy and width is also introduced.

Ulla, Ana; Manteiga, Minia

2004-12-01

This volume entittled "Lecture Notes and Essays in Astrophysics" is the first of a series containing the invited reviews and lectures presented during the biannual meetings of the Astrophysics Group of the spanish RSEF ("Real Sociedad Española de Física"). In particular, it includes the conferences and reviews presented during the meeting held at Madrid (Spain) on July 2003 during the First Centennial of the Spanish RSEF. The book is aimed to offer the specialized public, and particularly the astrophysics postgraduate students, selected comprehensive reviews on hot topics lectured by relevant speakers on the subject ("Lecture Notes"). The issue is complemented by a set of chapters on more specific topics ("Essays"). The turn of century has been rich with new discoveries, from the detections of extrasolar planets to the discovery of the the farthest galaxies ever seen or the detection of acceleration in the expansion of the Universe. Spain is leaving her imprint in the telescope making revolution and is promoting the construction of a 10.4 metre telescope in the ``Roque de Los Muchachos" observatory, in the Island of La Palma, Spain. This book provides an interesting insight on selected topics of modern Astrophysics as developped by Spanish astronomers.

"Pulse pair technique in high resolution NMR" a reprint of the historical 1971 lecture notes on two-dimensional spectroscopy.

PubMed

Jeener, Jean; Alewaeters, Gerrit

2016-05-01

The review articles published in "Progress in NMR Spectroscopy" are usually invited treatments of topics of current interest, but occasionally the Editorial Board may take an initiative to publish important historical material that is not widely available. The present article represents just such a case. Jean Jeener gave a lecture in 1971 at a summer school in Basko Polje, in what was then called Yugoslavia. As is now widely known, Jean Jeener laid down the foundations in that lecture of two - and higher - dimensional NMR spectroscopy by proposing the homonuclear COSY experiment. Jeener realized that the new proposal would open the door towards protein NMR and molecular structure determinations, but he felt that useful versions of such experiments could not be achieved with the NMR, computer and electronics technology available at that time, so that copies of the lecture notes were circulated (the Basko Polje lecture notes by J. Jeener and G. Alewaeters), but no formal publication followed. Fortunately, Ernst, Freeman, Griffin, and many others were more far-sighted and optimistic. An early useful extension was Ernst's proposal to replace the original projection/reconstruction technique of MRI by the widely adopted Fourier transform method inspired by the Basko Polje lecture. Later, the pulse method spread over many fields of spectroscopy as soon as the required technology became available. Jean Jeener, Emeritus professor, Université Libre de Bruxelles.

Vassilevski, P S

The Lecture Notes are primarily based on a sequence of lectures given by the author while been a Fulbright scholar at 'St. Kliment Ohridski' University of Sofia, Sofia, Bulgaria during the winter semester of 2009-2010 academic year. The notes are somewhat expanded version of the actual one semester class he taught there. The material covered is slightly modified and adapted version of similar topics covered in the author's monograph 'Multilevel Block-Factorization Preconditioners' published in 2008 by Springer. The author tried to keep the notes as self-contained as possible. That is why the lecture notes begin with some basic introductory matrix-vectormore » linear algebra, numerical PDEs (finite element) facts emphasizing the relations between functions in finite dimensional spaces and their coefficient vectors and respective norms. Then, some additional facts on the implementation of finite elements based on relation tables using the popular compressed sparse row (CSR) format are given. Also, typical condition number estimates of stiffness and mass matrices, the global matrix assembly from local element matrices are given as well. Finally, some basic introductory facts about stationary iterative methods, such as Gauss-Seidel and its symmetrized version are presented. The introductory material ends up with the smoothing property of the classical iterative methods and the main definition of two-grid iterative methods. From here on, the second part of the notes begins which deals with the various aspects of the principal TG and the numerous versions of the MG cycles. At the end, in part III, we briefly introduce algebraic versions of MG referred to as AMG, focusing on classes of AMG specialized for finite element matrices.« less

Using flashcards to support your learning.

Bryson, David

2012-03-01

The idea that if you listen to a lecture and make notes you will, by some mysterious process, have learnt all that the lecturer has covered, is a myth. Unfortunately, the lecture is just the start. The best way to learn is by doing. This can be achieved by completing set practical tasks by reading and creating your own notes, listening again to parts or the whole of a lecture via a screencast or using diagrams and illustrations that you annotate. Similarly creating your own learning materials can be useful as actually putting questions and answers together helps you to learn. One of the many ways to support your learning, especially in difficult topics like anatomy and physiology, learning about bones, medical terminology or indeed any subject where there are a lot of new words and terms to learn, is making use of an old technique brought up to date with new technologies called "flashcards".

PREFACE: Lectures from the CERN Winter School on Strings, Supergravity and Gauge Theories, CERN, 9-13 February 2009 Lectures from the CERN Winter School on Strings, Supergravity and Gauge Theories, CERN, 9-13 February 2009

NASA Astrophysics Data System (ADS)

Uranga, A. M.

2009-11-01

This special section is devoted to the proceedings of the conference `Winter School on Strings, Supergravity and Gauge Theories', which took place at CERN, the European Centre for Nuclear Research, in Geneva, Switzerland 9-13 February 2009. This event is part of a yearly series of scientific schools, which represents a well established tradition. Previous events have been held at SISSA, in Trieste, Italy, in February 2005 and at CERN in January 2006, January 2007 and January 2008, and were funded by the European Mobility Research and Training Network `Constituents, Fundamental Forces and Symmetries of the Universe'. The next event will take place again at CERN, in January 2010. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of several general lectures of four hours each, whose notes are published in this special section, and six working group discussion sessions, focused on specific topics of the network research program. It was well attended by over 200 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress, and to the open problems, in string theory. One of the most active areas in string theory in recent years has been the AdS/CFT or gauge/gravity correspondence, which proposes the complete equivalence of string theory on (asymptotically) anti de Sitter spacetimes with certain quantum (gauge) field theories. The duality has recently been applied to understanding the hydrodynamical properties of a hot plasma in gauge theories (like the quark-gluon plasma created in heavy ion collisions at the RHIC experiment at Brookhaven, and soon at the LHC at CERN) in terms of a dual gravitational AdS theory in the presence of a black hole. These developments were reviewed in the lecture notes by M Rangamani. In addition, the AdS/CFT duality has been proposed as a tool to study interesting physical properties in other physical systems described by quantum field theory, for instance in the context of a condensed matter system. The lectures by S Hartnoll provided an introduction to this recent development with an emphasis on the dual holographic description of superconductivity. Finally, ideas inspired by the AdS/CFT correspondence are yielding deep insights into fundamental questions of quantum gravity, like the entropy of black holes and its interpretation in terms of microstates. The lectures by S Mathur reviewed the black hole entropy and information paradox, and the proposal for its resolution in terms of `fuzzball' microstates. Further sets of lectures, not included in this special section, by F Zwirner and V Mukhanov, covered phenomenological aspects of high energy physics beyond the Standard Model and of cosmology. The coming experimental data in these two fields are expected to foster new developments in connecting string theory to the real world. The conference was financially supported by CERN and partially by the Arnold Sommerfeld Center for Theoretical Physics of the Ludwig Maximilians University of Munich. It is a great pleasure for us to warmly thank the Theory Unit of CERN for its very kind hospitality and for the high quality of the assistance and the infrastructures that it has provided.

Fuhs, A. E.

A comprehensive account is given of the principles that can be applied in military aircraft configuration studies to minimize the radar cross section (RCS) that will be presented by the resulting design to advanced radars under various mission circumstances. It is noted that, while certain ECM techniques can be nullified by improved enemy electronics in a very short time, RCS reductions may require as much as a decade of radar development before prior levels of detectability can be reestablished by enemy defenses. Attention is given to RCS magnitude determinants, inverse scattering, the polarization and scattering matrix, the RCSs of flat plates and conducting cylinders, and antenna geometry and beam patterns.

Note taking while attending a PPT requires high activity of memory and writing process which ultimately leads to what is called "death by power point" referring to boredom and fatigue.  To overcome this we planned to evaluate the impact of utilisation of uncompleted handouts given prior to PPT presentations. Final year MBBS students were divided in 2 batches, batch A and batch B.  For a set of lectures one batch was provided with handouts before lecture while the other batch was given lectures only. Crossover was done to avoid bias, all the lectures being given by the same presenter.  At the end of each lecture, a short questionnaire of 10 Multiple Choice Question (MCQ) was provided to the students. Mean scores were calculated for lectures with handouts and without handouts. For a set of lectures, when batch A was provided with handouts, the mean score was 28.2; for batch B to which no handouts were given the mean score was 23.4. Similarly, for batch B when provided with handouts the mean score was 29.1, for batch A which was not provided with handouts the mean score was 24. There was an average increase of 4.2 marks. Actual gain when handouts were provided was 1.2 marks per lecture.  It was more for the batch comprising of repeater students as compared to the batch of fresher students. Increase in attendance was also noted. Providing uncompleted handouts before a didactic lecture definitely results in increase in knowledge gain; repeater students benefit more with uncompleted handouts.

Social media interruption affects the acquisition of visually, not aurally, acquired information during a pathophysiology lecture.

Poor academic performance from extensive social media usage appears to be due to students' inability to multitask between distractions and academic work. However, the degree to which visually distracted students can acquire lecture information presented aurally is unknown. This study examined the ability of students visually distracted by social media to acquire information presented during a voice-over PowerPoint lecture, and to compare performance on examination questions derived from information presented aurally vs. that presented visually. Students ( n = 20) listened to a 42-min cardiovascular pathophysiology lecture containing embedded cartoons while taking notes. The experimental group ( n = 10) was visually, but not aurally, distracted by social media during times when cartoon information was presented, ~40% of total lecture time. Overall performance among distracted students on a follow-up, open-note quiz was 30% poorer than that for controls ( P < 0.001). When the modality of presentation (visual vs. aural) was compared, performance decreased on examination questions from information presented visually. However, performance on questions from information presented aurally was similar to that of controls. Our findings suggest the ability to acquire information during lecture may vary, depending on the degree of competition between the modalities of the distraction and the lecture presentation. Within the context of current literature, our findings also suggest that timing of the distraction relative to delivery of material examined affects performance more than total distraction time. Therefore, when delivering lectures, instructors should incorporate organizational cues and active learning strategies that assist students in maintaining focus and acquiring relevant information.

Effective use of pause procedure to enhance student engagement and learning.

Active learning strategies have been documented to enhance learning. We created an active learning environment in neuromuscular physiology lectures for first year medical students by using 'Pause Procedure'. One hundred and fifty medical students class is divided into two Groups (Group A and Group B) and taught in different classes. Each lecture of group A (experimental Group) undergraduate first year medical students was divided into short presentations of 12-15 min each. Each presentation was followed by a pause of 2-3min, three times in a 50 min lecture. During the pauses students worked in pairs to discuss and rework their notes. Any queries were directed towards the teacher and discussed forthwith. At the end of each lecture students were given 2-3 minutes to write down the key points they remembered about the lecture (free-recall). Fifteen days after completion of the lectures a 30 item MCQ test was administered to measure long term recall. Group B (control Group) received the same lectures without the use of pause procedure and was similarly tested. Experimental Group students did significantly better on the MCQ test (p-value<0.05) in comparison to the control Group. Most of the students (83.6%) agreed that the 'pause procedure' helped them to enhance lecture recall. Pause procedure is a good active learning strategy which helps students review their notes, reflect on them, discuss and explain the key ideas with their partners. Moreover, it requires only 6-7 min of the classroom time and can significantly enhance student learning.

Assisting at-risk community college students' acquisition of critical thinking learning strategies in human anatomy and physiology

NASA Astrophysics Data System (ADS)

Arburn, Theresa Morkovsky

1998-11-01

The purpose of this study was to investigate whether learning thinking strategies within the context of a community college course in Human Anatomy and Physiology would result in increased academic performance and the incidence of critical thinking skills. Included in the study sample were 68 community college students, many of whom would be categorized as "at-risk," who were enrolled in four sections of a Human Anatomy and Physiology class. Two of the class sections served as the experimental group and two sections served as the control group. During the course of one semester, members of the experimental group participated in the use of a student-generated questioning technique in conjunction with lecture presentations, while members of the control group did not. All students were pretested using the Learning and Study Strategies Inventory (LASSI) and the California Critical Thinking Skills Test (CCTST). Posttesting was completed using these same instruments and an end-of-course comprehensive examination. Analysis of data revealed no significant differences between the experimental and control groups with regard to their overall achievement, their ability to process information, or their demonstration of critical thinking. It was interesting to note, however, that members of the experimental group did exhibit a change in their ability to select main ideas, apply deductive reasoning, and use inference. While the use of thinking strategies within the context of the course did not effect a significant change in academic achievement or critical thinking among at-risk community college students, it should be noted that application of a non-lecture method of class participation had no negative impact on student performance. Whether more abstruse changes have occurred with regard to the acquisition of cognitive skills remains to be elucidated.

Effects of random study checks and guided notes study cards on middle school special education students' notetaking accuracy and science vocabulary quiz scores

NASA Astrophysics Data System (ADS)

Wood, Charles L.

Federal legislation mandates that all students with disabilities have meaningful access to the general education curriculum and that students with and without disabilities be held equally accountable to the same academic standards (IDEIA, 2004; NCLB, 2001). Many students with disabilities, however, perform poorly in academic content courses, especially at the middle and secondary school levels. Previous research has reported increased notetaking accuracy and quiz scores over lecture content when students completed guided notes compared to taking their own notes. This study evaluated the effects of a pre-quiz review procedure and specially formatted guided notes on middle school special education students' learning of science vocabulary. This study compared the effects of three experimental conditions. (a) Own Notes (ON), (b) Own Notes+Random Study Checks (ON+RSC), and (c) Guided Notes Study Cards+Random Study Checks (GNSC+RSC) on each student's accuracy of notes, next-day quiz scores, and review quiz scores. Each session, the teacher presented 12 science vocabulary terms and definitions during a lecture and students took notes. The students were given 5 minutes to study their notes at the end of each session and were reminded to study their notes at home and in study hall period. In the ON condition students took notes on a sheet of paper with numbered lines from 1 to 12. Just before each next-day quiz in the ON+RSC condition students used write-on response cards to answer two teacher-posed questions over randomly selected vocabulary terms from the previous day's lecture. If the answer on a randomly selected student's response card was correct, that student earned a lottery ticket for inexpensive prizes and a quiz bonus point for herself and each classmate. In the GNSC+RSC condition students took notes on specially formatted guided notes that after the lecture they cut into a set of flashcards that could used for study. The students' mean notetaking accuracy was 75% during ON, 89% during ON+RSC, and 99.5% during GNSC+RSC. The class mean scores on next-day quizzes during ON, ON+RSC, and GNSC+RSC was 39%, 68%, and 90%, respectively. The class mean score on review quizzes following ON, ON+RSC, and GNSC+RSC was 2.1, 5.3, and 7.8 (maximum score, 10), respectively. Results for five of the seven students provide convincing evidence of functional relationships between ON+RSC and higher quiz scores compared to ON and between GNSC+RSC and higher quiz scores compared to ON+RSC. Students', teachers', and parents' opinions regarding the RSC and GNSC procedures were highly favorable.

Lecturing with a Virtual Whiteboard

NASA Astrophysics Data System (ADS)

Milanovic, Zoran

2006-09-01

Recent advances in computer technology, word processing software, and projection systems have made traditional whiteboard lecturing obsolete. Tablet personal computers connected to display projectors and running handwriting software have replaced the marker-on-whiteboard method of delivering a lecture. Since the notes can be saved into an electronic file, they can be uploaded to a class website to be perused by the students later. This paper will describe the author's experiences in using this new technology to deliver physics lectures at an engineering school. The benefits and problems discovered will be reviewed and results from a survey of student opinions will be discussed.

How is that done? Student views on resources used outside the engineering classroom

NASA Astrophysics Data System (ADS)

Maclaren, Peter

2018-07-01

While the traditional lecture remains a key feature in the teaching of mathematically intensive disciplines at a tertiary level, what students do outside class, the resources they use, and how they use them are critical factors in their success. This study reports on a survey of students studying a range of engineering subjects, giving their views on the effectiveness of resources that they use outside the classroom. Resource types examined included textbooks, lecturer course notes, in-class developed notes, and other online material, including multimedia. While lecturer-generated material was generally seen as more effective than formal textbooks and social media, external screencasts were rated as most effective where material appropriate to their class was available. It is suggested that student use of screencast resources has the potential to facilitate improved learning outcomes, and with accompanying changes in assessment focus, may enable more substantive pedagogical changes.

Student learning and perceptions in a flipped linear algebra course

NASA Astrophysics Data System (ADS)

Love, Betty; Hodge, Angie; Grandgenett, Neal; Swift, Andrew W.

2014-04-01

The traditional lecture style of teaching has long been the norm in college science, technology, engineering, and mathematics (STEM) courses, but an innovative teaching model, facilitated by recent advances in technology, is gaining popularity across college campuses. This new model inverts or 'flips' the usual classroom paradigm, in that students learn initial course concepts outside of the classroom, while class time is reserved for more active problem-based learning and practice activities. While the flipped classroom model shows promise for improving STEM learning and increasing student interest in STEM fields, discussions to date of the model and its impact are more anecdotal than data driven - very little research has been undertaken to rigorously assess the potential effects on student learning that can result from the flipped classroom environment. This study involved 55 students in 2 sections of an applied linear algebra course, using the traditional lecture format in one section and the flipped classroom model in another. In the latter, students were expected to prepare for the class in some way, such as watching screencasts prepared by the instructor, or reading the textbook or the instructor's notes. Student content understanding and course perceptions were examined. Content understanding was measured by the performance on course exams, and students in the flipped classroom environment had a more significant increase between the sequential exams compared to the students in the traditional lecture section, while performing similarly in the final exam. Course perceptions were represented by an end-of-semester survey that indicated that the flipped classroom students were very positive about their experience in the course, and particularly appreciated the student collaboration and instructional video components.

During the last two years, course notes, supplemental material, bulletin boards, and an interactive quiz system have been developed for the introductory astronomy course at George Mason University. In this talk, I will present results about the level of Web literacy, Web usage, and educational effectiveness of this system based on in-class surveys and test results. The results presented are based on a 300 person survey course composed primarily of non-science majors. Although this course currently includes a lecture section, we plan to offer this as a web-based distance learning course within six months.

Black Holes and Qubits

NASA Astrophysics Data System (ADS)

Borsten, L.; Duff, M. J.; Rubens, W.

These notes have been compiled to accompany a series of four lectures given at the Kinki University Quantum Computing Series Summer School on Decoherence, Entanglement and Entropy, August 2009 at the Oxford Kobe Institute (Kobe, Japan). Each of the four lectures focuses on a particular topic falling under the broad umbrella of the "black-hole/qubit correspondence". Lecture I introduces the first instance of the black-hole/qubit correspondence, the relationship between the entanglement of three qubits and the entropy of STU black holes. Lecture II develops this correspondence to the case of {N} = 8 black holes and the tripartite entanglement of seven qubits. Lecture III examines the use of Jordan algebras and the Freudenthal triple system, which capture the U-duality symmetries of these black hole systems, in entanglement classification. Lecture IV introduces the superqubit, a natural candidate to represent supersymmetric quantum information. These lectures draw on work done with D. Dahanayake, H. Ebrahim, S. Ferrara and A. Marrani whose efforts are most gratefully acknowledged.

Mechanical Design of Spacecraft

NASA Technical Reports Server (NTRS)

1962-01-01

In the spring of 1962, engineers from the Engineering Mechanics Division of the Jet Propulsion Laboratory gave a series of lectures on spacecraft design at the Engineering Design seminars conducted at the California Institute of Technology. Several of these lectures were subsequently given at Stanford University as part of the Space Technology seminar series sponsored by the Department of Aeronautics and Astronautics. Presented here are notes taken from these lectures. The lectures were conceived with the intent of providing the audience with a glimpse of the activities of a few mechanical engineers who are involved in designing, building, and testing spacecraft. Engineering courses generally consist of heavily idealized problems in order to allow the more efficient teaching of mathematical technique. Students, therefore, receive a somewhat limited exposure to actual engineering problems, which are typified by more unknowns than equations. For this reason it was considered valuable to demonstrate some of the problems faced by spacecraft designers, the processes used to arrive at solutions, and the interactions between the engineer and the remainder of the organization in which he is constrained to operate. These lecture notes are not so much a compilation of sophisticated techniques of analysis as they are a collection of examples of spacecraft hardware and associated problems. They will be of interest not so much to the experienced spacecraft designer as to those who wonder what part the mechanical engineer plays in an effort such as the exploration of space.

The European computer driving licence and the use of computers by dental students.

PubMed

Antonarakis, G S

2009-02-01

The use of computers within the dental curriculum for students is vital for many aspects of their studies. The aim of this study was to assess how dental students who had obtained the European computer driving licence (ECDL) qualification (an internationally-recognised standard of competence) through taught courses, felt about the qualification, and how it changed their habits vis-à-vis computers, and information and communication technology. This study was carried out as a descriptive, one-off, cross-sectional survey. A questionnaire was distributed to 100 students who had successfully completed the course, with questions pertaining to the use of email, word processing and Internet for course-works, Medline for research, computer based learning, online lecture notes, and online communication with members of staff, both before and after ECDL qualification. Scaled responses were given. The attitudes of students towards the course were also assessed. The frequencies and percentage distributions of the responses to each question were analysed. It was found that dental students who follow ECDL teaching and successfully complete its requirements, seem to increase the frequency with which they use email, word processing and Internet for course works, Medline for research purposes, computer based learning, online lecture notes, and online communication with staff. Opinions about the ECDL course varied, many dental students finding the course easy, enjoying it only a little, but admitting that it improved their computer skills.

Use of World Wide Web server and browser software to support a first-year medical physiology course.

PubMed

Davis, M J; Wythe, J; Rozum, J S; Gore, R W

1997-06-01

We describe the use of a World Wide Web (Web) server to support a team-taught physiology course for first-year medical students. Our objectives were to reduce the number of formal lecture hours and enhance student enthusiasm by using more multimedia materials and creating opportunities for interactive learning. On-line course materials, consisting of administrative documents, lecture notes, animations, digital movies, practice tests, and grade reports, were placed on a departmental computer with an Internet connection. Students used Web browsers to access on-line materials from a variety of computing platforms on campus, at home, and at remote sites. To assess use of the materials and their effectiveness, we analyzed 1) log files from the server, and 2) the results of a written course evaluation completed by all students. Lecture notes and practice tests were the most-used documents. The students' evaluations indicated that computer use in class made the lecture material more interesting, while the on-line documents helped reinforce lecture materials and the textbook. We conclude that the effectiveness of on-line materials depends on several different factors, including 1) the number of instructors that provide materials; 2) the quantity of other materials handed out; 3) the degree to which computer use is demonstrated in class and integrated into lectures; and 4) the ease with which students can access the materials. Finally, we propose that additional implementation of Internet-based resources beyond what we have described would further enhance a physiology course for first-year medical students.

Essentially Non-Oscillatory and Weighted Essentially Non-Oscillatory Schemes for Hyperbolic Conservation Laws

NASA Technical Reports Server (NTRS)

Shu, Chi-Wang

1997-01-01

In these lecture notes we describe the construction, analysis, and application of ENO (Essentially Non-Oscillatory) and WENO (Weighted Essentially Non-Oscillatory) schemes for hyperbolic conservation laws and related Hamilton- Jacobi equations. ENO and WENO schemes are high order accurate finite difference schemes designed for problems with piecewise smooth solutions containing discontinuities. The key idea lies at the approximation level, where a nonlinear adaptive procedure is used to automatically choose the locally smoothest stencil, hence avoiding crossing discontinuities in the interpolation procedure as much as possible. ENO and WENO schemes have been quite successful in applications, especially for problems containing both shocks and complicated smooth solution structures, such as compressible turbulence simulations and aeroacoustics. These lecture notes are basically self-contained. It is our hope that with these notes and with the help of the quoted references, the reader can understand the algorithms and code them up for applications.

2017-05-01

The use of external representations (ERs) to introduce concepts in undergraduate biology has become increasingly common. Two of the most prevalent are static images and dynamic animations. While previous studies comparing static images and dynamic animations have resulted in somewhat conflicting findings in regards to learning outcomes, the benefits of each have been shown individually. Using ERs developed by the Virtual Cell Animation project, we aim to further investigate student learning using different ERs as part of an introductory biology lecture. We focus our study on the topic of photosynthesis as reports have noted that students struggle with a number of basic photosynthesis concepts. Students (n = 167) in ten sections of introductory biology laboratory were introduced to photosynthesis concepts by instructional lectures differing only in the format of the embedded ERs. Normalized gain scores were calculated, showing that students who learned with dynamic animations outperformed students who learned from static images on the posttest. The results of this study provide possible instructional guidelines for those delivering photosynthesis instruction in the introductory biology classroom. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(3):226-234, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

A Delicate Balance: Integrating Active Learning into a Large Lecture Course

PubMed Central

Cotner, Sehoya H.; Baepler, Paul M.; Decker, Mark D.

2008-01-01

A lecture section of introductory biology that historically enrolled more than 500 students was split into two smaller sections of approximately 250 students each. A traditional lecture format was followed in the “traditional” section; lecture time in the “active” section was drastically reduced in favor of a variety of in-class student-centered activities. Students in both sections took unannounced quizzes and multiple-choice exams. Evaluation consisted of comparisons of student survey responses, scores on standardized teaching evaluation forms, section averages and attendance, and open-ended student comments on end-of-term surveys. Results demonstrate that students perform as well, if not better, in an active versus traditional environment. However, student concerns about instructor expectations indicate that a judicious balance of student-centered activities and presentation-style instruction may be the best approach. PMID:19047423

First Steps Toward Increasing Student Engagement During Lecture

NASA Astrophysics Data System (ADS)

Slater, Timothy F.

2008-05-01

Have you tried to repurpose materials you've gotten from another lecturer or publisher that you thought could express a concept exceptionally well, only to find when you used the same materials, they did not have the dramatic effect on your students you desired? It would be easy to conclude that student apathy is to blame. But, if students listening to your lecture take on the same bored appearance and passive disposition often observed when you are showing a video, consider whether your instructional approach is designed to intellectually engage students. An information-download lecture has often been described as…the process by which the teacher's notes get transferred into students' notebooks without passing through the brains of either. That brilliant set of lecture materials that you thought would be perfect might need to be adjusted to meet the learning styles of your students to actively engage them in developing conceptual understanding.

Mathematics lecturing in the digital age

Trenholm, Sven; Alcock, Lara; Robinson, Carol L.

2012-09-01

In this article, we consider the transformation of tertiary mathematics lecture practice. We undertake a focused examination of the related research with two goals in mind. First, we document this research, reviewing the findings of key studies and noting that reflective pieces on individual practice as well as surveys are more prevalent than empirical studies. Second, we investigate issues related to the transformation of lecture practice by the emergence of e-lectures. We discuss the latter in terms of claims about the efficiencies offered by new technologies and contrast these with possible disadvantages in terms of student engagement in a learning community. Overall findings indicate that while survey results appear to trumpet the value of e-lecture provision, empirical study results appear to call that value into question. Two explanatory theoretical frameworks are presented. Issues concerning the instructional context (e.g. the nature of mathematical thinking), inherent complexities and recommendations for implementation are discussed.

Comparative use of podcasts vs. lecture transcripts as learning aids for dental students.

PubMed

Allen, Kenneth L; Katz, Ralph V

2011-06-01

The purpose of this project was to describe dental students' use of lecture podcasts versus written lecture transcripts as learning aids under three different circumstances: studying for an exam, reviewing an attended lecture, and reviewing a missed lecture. Additional analyses were performed to see whether demographic differences (e.g., age, gender, language skills, and computer skills) or grade differences were associated with preferences for using podcast versus written lecture transcripts of class notes. Fifty-one percent (n=171) of the second-year dental students at the New York University College of Dentistry voluntarily participated in this survey. The major findings were that 1) a high percentage of students (70-92 percent) used one or both aids in all three utilization circumstances with a consistent preference for podcast use, especially when reviewing a missed lecture; 2) course grades were not associated with the preferred use of either lecture aid; and 3) over half the students listened to the podcasts at speeds that were one and one-half or two times faster than normal speech, especially younger students. Further studies are warranted to delve into the current student generation's preferred learning styles and the resultant learning outcomes associated with those preferences.

Why do students miss lectures? A study of lecture attendance amongst students of health science.

PubMed

Bati, A Hilal; Mandiracioglu, Aliye; Orgun, Fatma; Govsa, Figen

2013-06-01

In the domain of health sciences, attendance by students at lectures is more critical. Lecture attendance is an issue which has been widely neglected. This study aims to determine those factors which affect the lecture attendance. The research data was collected by means of a questionnaire during the second semester of the academic year 2010-2011 from second-year students of the Faculties of Medicine, Pharmacy, Dentistry and Nursing. Together with demographic data, the questionnaire includes a Likert-type scale aiming to determine the factors influencing attendance at lectures. 663 participated in this study on a voluntary basis from Medical, Dentistry, Pharmacy and Nursing Faculties. Raising attainment levels, being able to take their own lecture notes, learning which aspects of the lecture content were being emphasized, and the opportunity to ask questions were amongst the chief reasons for attending lectures. It appears that the factors preventing students from attending lectures are mainly individual. Amongst the most frequently cited causes of non-attendance, sleeplessness, ill health and the inefficiency of lectures in overcrowded halls are emphasized. In the totals and sub-dimensions of the Lecture Attendance Scale, Medical Faculty students have average scores higher than those of students at other faculties. The vital nature of professional expertise and its applications, health sciences students' attendance at lectures carries greater importance. It is important to strengthen the mentoring system with regard to individual and external factors, which have been implicated as having a substantial influence on lecture attendance by students.

The Web-Lecture - a viable alternative to the traditional lecture format?

NASA Astrophysics Data System (ADS)

Meibom, S.

2004-12-01

Educational research shows that students learn best in an environment with emphasis on teamwork, problem-solving, and hands-on experience. Still professors spend the majority of their time with students in the traditional lecture-hall setting where the combination of large classes and limited time prevents sufficient student-teacher interaction to foster an active learning environment. Can modern computer technology be used to provide "lecture-type" information to students via the World Wide Web? If so, will that help professors make better and/or different use of their scheduled time with the students? Answering these questions was the main motivation for the Extra-Solar Planet Project. The Extra-Solar Planet Project was designed to test the effectiveness of a lecture available to the student on the World Wide Web (Web-Lecture) and to engage the students in an active learning environment were their use the information presented in the Web-Lecture. The topic of the Web-Lecture was detection of extra-solar planets and the project was implemented into an introductory astronomy course at University of Wisconsin Madison in the spring of 2004. The Web-Lecture was designed to give an interactive presentation of synchronized video, audio and lecture notes. It was created using the eTEACH software developed at the University of Wisconsin Madison School of Engineering. In my talk, I will describe the project, show excerpts of the Web-Lecture, and present assessments of student learning and results of student evaluations of the web-lecture format.

The clinical note is a cornerstone of physician communication, yet there are few published interventions on teaching note writing in the electronic health record (EHR). This is a prospective, two-site, quality improvement project to assess and improve the quality of clinical documentation in the EHR using a validated assessment tool. Internal Medicine (IM) residents at the University of Kentucky College of Medicine (UK) and Montefiore Medical Center/Albert Einstein College of Medicine (MMC) received one of two interventions during an inpatient ward month: either a lecture, or a lecture and individual feedback on progress notes. A third group of residents in each program served as control. Notes were evaluated with the Physician Documentation Quality Instrument 9 (PDQI-9). Due to a significant difference in baseline PDQI-9 scores at MMC, the sites were not combined. Of 75 residents at the UK site, 22 were eligible, 20 (91%) enrolled, 76 notes in total were scored. Of 156 residents at MMC, 22 were eligible, 18 (82%) enrolled, 40 notes in total were scored. Note quality did not improve as measured by the PDQI-9. This educational quality improvement project did not improve the quality of clinical documentation as measured by the PDQI-9. This project underscores the difficulty in improving note quality. Further efforts should explore more effective educational tools to improve the quality of clinical documentation in the EHR.

The effectiveness of computer-generated 3D animations in inquiry chemistry laboratory

NASA Astrophysics Data System (ADS)

Theall, Rachel Morgan

It has been shown that students need a molecular-level understanding of substances in order to comprehend chemistry. For solid structures, atomic-level understanding requires students to learn additional and different concepts than for other states of matter. To aid understanding, animations were created to model unit cell structures and depict the properties of unit cells. In order to determine if these animations are helpful to students, they were tested during a laboratory exercise in which students had previously been using model kits and images from textbooks to learn about solid structures. Students evaluated in this study were from two lecture sections of general chemistry, one that routinely used animations during lecture and one that used a more traditional lecture format that did not include animations or models. Twelve laboratory sections of these lectures, taught by six different instructors each teaching two sections, were chosen for participation. One section for each instructor was given the animations as an optional tool for completing the laboratory assignment, which consisted of questions about unit cells and crystal structures. The results of the study indicate that students who looked at the animations performed significantly better on the assignment. For the control group, students who routinely viewed multiple representations of chemistry in lecture performed significantly better on the lab assignment than students in the lecture section where chemistry concepts were only presented on the chalkboard and overhead projector. Students in the traditional lecture section also had significantly less appreciation for the model kits used in the laboratory than students in the other lecture section. Observations of students in the lab combined with statistical results led to the revision of the solid structures investigation. Additional animations were created and inserted into the module that covered areas where students indicated more help was needed. Movies of "real life" chemistry were also incorporated into the module to help students relate the investigation to prior knowledge.

Note-taking and Handouts in The Digital Age.

Most educators consider note-taking a critical component of formal classroom learning. Advancements in technology such as tablet computers, mobile applications, and recorded lectures are altering classroom dynamics and affecting the way students compose and review class notes. These tools may improve a student's ability to take notes, but they also may hinder learning. In an era of dynamic technology developments, it is important for educators to routinely examine and evaluate influences on formal and informal learning environments. This paper discusses key background literature on student note-taking, identifies recent trends and potential implications of mobile technologies on classroom note-taking and student learning, and discusses future directions for note-taking in the context of digitally enabled lifelong learning.

Pompe van Meerdervoort arrived at Nagasaki port on September 21, 1857 and started his western-style medical education for the first time in the Nishiyakusho of Nagasaki on November 12, 1857. He had 12 students including Ryojun Matsumono. The curriculum was largely based on that of Utrecht Army Medical School, which was re-organized after 1841 and very good in balance of theory and practice. Among subjects, much attention was paid for Anatomy which was quite advancing at the time and in fact the lecture was given on every Tuesday, Thursday and Saturday morning from 1857 to the end of 1859. His lecture note on Anatomy was based on Handboek der Ontleedkunde van den Mensch originally written by C. E. Bock, which was translated into Dutch by P. H. Pool. The note currently available is a copy by the students. In Europe of those days, microscopes were developed and "Histology" had been established as a new science. Therefore, his lecture contained details of histological findings and now we can appreciate his policy to think much of Anatomy in the introduction of western-style medical education.

Interteaching is a new method of classroom instruction that is based on behavioral principles but offers more flexibility than other behaviorally based methods. We examined the effectiveness of interteaching relative to a traditional form of classroom instruction-the lecture. In Study 1, participants in a graduate course in special education took short quizzes after alternating conditions of interteaching and lecture. Quiz scores following interteaching were higher than quiz scores following lecture, although both methods improved performance relative to pretest measures. In Study 2, we also alternated interteaching and lecture but counterbalanced the conditions across two sections of an undergraduate research methods class. After each unit of information, participants from both sections took the same test. Again, test scores following interteaching were higher than test scores following lecture. In addition, students correctly answered more interteaching-based questions than lecture-based questions on a cumulative final test. In both studies, the majority of students reported a preference for interteaching relative to traditional lecture. In sum, the results suggest that interteaching may be an effective alternative to traditional lecture-based methods of instruction.

The recent emergence and popularity of online educational resources brings with it challenges for educators to optimize the dissemination of online content. Here we provide evidence that points toward a solution for the difficulty that students frequently report in sustaining attention to online lectures over extended periods. In two experiments, we demonstrate that the simple act of interpolating online lectures with memory tests can help students sustain attention to lecture content in a manner that discourages task-irrelevant mind wandering activities, encourages task-relevant note-taking activities, and improves learning. Importantly, frequent testing was associated with reduced anxiety toward a final cumulative test and also with reductions in subjective estimates of cognitive demand. Our findings suggest a potentially key role for interpolated testing in the development and dissemination of online educational content.

Evaluating the impact of a classroom response system in a microbiology course.

Suchman, Erica; Uchiyama, Kay; Smith, Ralph; Bender, Kim

2006-05-01

The use of a Classroom Response System (CRS) was evaluated in two sections, A and B, of a large lecture microbiology course. In Section B the instructor used the CRS technology at the beginning of the class period posing a question on content from the previous class. Students could earn extra credit if they answered the question correctly. In Section A, the class also began with an extra credit CRS question. However, CRS questions were integrated into the lecture during the entire class period. We compared the two classes to see if augmenting lectures with this technology increased student learning, confidence, attendance, and the instructor's ability to respond to student's misconceptions, over simply using the CRS as a quizzing tool. Student performance was compared using shared examination questions. The questions were categorized by how the content had been presented in class. All questions came from instructors' common lecture content, some without CRS use, and some questions where Instructor A used both lecture and CRS questions. Although Section A students scored significantly better on both types of examination questions, there was no demonstrable difference in learning based on CRS question participation. However, student survey data showed that students in Section A expressed higher confidence levels in their learning and knowledge and indicated that they interacted more with other students than did the students in Section B. In addition, Instructor A recorded more modifications to lecture content and recorded more student interaction in the course than did Instructor B.

Enhancing learning: A comparison of lecture and gaming outcomes.

PubMed

Gipson, Mary; Bear, Mary

2013-01-01

Contrary to what we anticipated, our outcomes indicated that learning and satisfaction with learning were no different between the traditional lecture group and the educational gaming group. Learners in the gaming group scored on the examination just as well as, but no higher than, did those in the lecture group. Similarly, students in the gaming group were just as, but no more, satisfied with their learning than were students in the lecture group. Of note, both teaching/learning strategies were shown to be effective for learning with students earning a B average on the examination. Likewise, students in both groups were very satisfied with their respective teaching/learning strategies. Given that our assessment did not support gaming as a superior teaching/learning strategy over lecture, what remains now is the need for a longitudinal study to determine if there are differences in long-term learning. As we implement creative methods of instruction, it is also important to test their effectiveness to ensure that the teaching-learning process is evidence based.

To examine faculty members' and students' use and perceptions of lecture recordings in a previously implemented lecture-capture initiative. Patterns of using lecture recordings were determined from software analytics, and surveys were conducted to determine awareness and usage, effect on attendance and other behaviors, and learning impact. Most students and faculty members were aware of and appreciated the recordings. Students' patterns of use changed as the novelty wore off. Students felt that the recordings enhanced their learning, improved their in-class engagement, and had little effect on their attendance. Faculty members saw little difference in students' grades or in-class engagement but noted increased absenteeism. Students made appropriate use of recordings to support their learning, but faculty members generally did not make active educational use of the recordings. Further investigation is needed to understand the effects of lecture recordings on attendance. Professional development activities for both students and faculty members would help maximize the learning benefits of the recordings.

This Teaching Resource provides lecture notes, slides, and a student assignment for a lecture on probabilistic reasoning in the analysis of biological data. General probabilistic frameworks are introduced, and a number of standard probability distributions are described using simple intuitive ideas. Particular attention is focused on random arrivals that are independent of prior history (Markovian events), with an emphasis on waiting times, Poisson processes, and Poisson probability distributions. The use of these various probability distributions is applied to biomedical problems, including several classic experimental studies.

The pen is mightier than the keyboard: advantages of longhand over laptop note taking.

PubMed

Mueller, Pam A; Oppenheimer, Daniel M

2014-06-01

Taking notes on laptops rather than in longhand is increasingly common. Many researchers have suggested that laptop note taking is less effective than longhand note taking for learning. Prior studies have primarily focused on students' capacity for multitasking and distraction when using laptops. The present research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing. In three studies, we found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. We show that whereas taking more notes can be beneficial, laptop note takers' tendency to transcribe lectures verbatim rather than processing information and reframing it in their own words is detrimental to learning. © The Author(s) 2014.

2016-01-01

Objective. To evaluate student perception and time spent on asynchronous online lectures in a blended learning environment (BLE) and to assess faculty workload and perception. Methods. Students (n=427) time spent viewing online lectures was measured in three courses. Students and faculty members completed a survey to assess perceptions of a BLE. Faculty members recorded time spent creating BLEs. Results. Total time spent in the BLE was less than the allocated time for two of the three courses by 3-15%. Students preferred online lectures for their flexibility, students’ ability to apply information learned, and congruence with their learning styles. Faculty members reported the BLE facilitated higher levels of learning during class sessions but noted an increase in workload. Conclusion. A BLE increased faculty workload but was well received by students. Time spent viewing online lectures was less than what was allocated in two of the three courses. PMID:27667839

Digital Note-Taking: Discussion of Evidence and Best Practices.

PubMed

Grahame, Jason A

2016-03-01

Balancing active course engagement and comprehension with producing quality lecture notes is challenging. Although evidence suggests that handwritten note-taking may improve comprehension and learning outcomes, many students still self-report a preference for digital note-taking and a belief that it is beneficial. Future research is warranted to determine the effects on performance of digitally writing notes. Independent of the methods or software chosen, best practices should be provided to students with information to help them consciously make an educated decision based on the evidence and their personal preference. Optimal note-taking requires self-discipline, focused attention, sufficient working memory, thoughtful rewording, and decreased distractions. Familiarity with the tools and mediums they choose will help students maximize working memory, produce better notes, and aid in their retention of material presented.

To expose residents to two methods of education for point-of-care ultrasound, a traditional didactic lecture and a model/simulation-based lecture, which focus on concepts of cardiopulmonary function, volume status, and evaluation of severe thoracic/abdominal injuries; and to assess which method is more effective. Single-center, prospective, blinded trial. University hospital. Anesthesiology residents who were assigned to an educational day during the two-month research study period. Residents were allocated to two groups to receive either a 90-minute, one-on-one didactic lecture or a 90-minute lecture in a simulation center, during which they practiced on a human model and simulation mannequin (normal pathology). Data points included a pre-lecture multiple-choice test, post-lecture multiple-choice test, and post-lecture, human model-based examination. Post-lecture tests were performed within three weeks of the lecture. An experienced sonographer who was blinded to the education modality graded the model-based skill assessment examinations. Participants completed a follow-up survey to assess the perceptions of the quality of their instruction between the two groups. 20 residents completed the study. No differences were noted between the two groups in pre-lecture test scores (P = 0.97), but significantly higher scores for the model/simulation group occurred on both the post-lecture multiple choice (P = 0.038) and post-lecture model (P = 0.041) examinations. Follow-up resident surveys showed significantly higher scores in the model/simulation group regarding overall interest in perioperative ultrasound (P = 0.047) as well understanding of the physiologic concepts (P = 0.021). A model/simulation-based based lecture series may be more effective in teaching the skills needed to perform a point-of-care ultrasound examination to anesthesiology residents.

The International Year of Light 2015 was designed to raise awareness of light sciences. In order to raise awareness, events were encouraged to get the public involved. Both Central Carolina Community College (CCCC) and Indian River State College (IRSC) held a total of three lectures in 2015 celebrating the IYL 2015. IRSC hosted lectures on March 6th and June 11th. CCCC hosted a lecture on November 17th. These lectures drew a total of over 400 attendees. Lectures revolved around their own unique themes relating to light sciences in industry and academia. With great support from Laser-Tec, SPIE, and NSF, these lectures were successful at exposing and advertising the optics field to the public, as well as promising up-and-coming students. These lectures hosted several keynote speakers on behalf of both industry and academia. The speakers were successful at keeping the audience engaged through presentations and question-and-answer sessions. In addition, lab tours allowed the attendees a chance to see the programs in action. Many takeaways will prove to be invaluable when pursuing such events in the future. This paper will not only speak to the tremendous success of these lectures, but will take an honest look at the areas for improvement. It is important to note that independent events can be held for the expansion of local programs leading to national, if not global, increase in communal awareness and participation. These events will serve as a continuation for what the IYL 2015 was designed.

2016-12-01

This Point/Counterpoint discusses the long-argued debate over whether lecture attendance in dental school at the predoctoral level should be required. Current educational practice relies heavily on the delivery of content in a traditional lecture style. Viewpoint 1 asserts that attendance should be required for many reasons, including the positive impact that direct contact of students with faculty members and with each other has on learning outcomes. In lectures, students can more easily focus on subject matter that is often difficult to understand. A counter viewpoint argues that required attendance is not necessary and that student engagement is more important than physical classroom attendance. This viewpoint notes that recent technologies support active learning strategies that better engage student participation, fostering independent learning that is not supported in the traditional large lecture classroom and argues that dental education requires assimilation of complex concepts and applying them to patient care, which passing a test does not ensure. The two positions agree that attendance does not guarantee learning and that, with the surge of information technologies, it is more important than ever to teach students how to learn. At this time, research does not show conclusively if attendance in any type of setting equals improved learning or ability to apply knowledge.

The lecture notes cover the basic principles of computational fluid dynamics (CFD). They are oriented more toward practical applications than theory, and are intended to serve as a unified source for basic material in the CFD field as well as an introduction to more specialized topics in artificial viscosity and boundary conditions. Each chapter in the test is associated with a videotaped lecture. The basic properties of conservation laws, wave equations, and shock waves are described. The duality of the conservation law and wave representations is investigated, and shock waves are examined in some detail. Finite difference techniques are introduced for the solution of wave equations and conservation laws. Stability analysis for finite difference approximations are presented. A consistent description of artificial viscosity methods are provided. Finally, the problem of nonreflecting boundary conditions are treated.

Background Didactic lecture is the oldest and most commonly used method of teaching. In addition, it is considered one of the most efficient ways to disseminate theories, ideas, and facts. Many critics feel that lectures are an obsolete method to use when students need to perform hands-on activities, which is an everyday need in the study of medicine. This study evaluates students’ perceptions regarding lecture quality in a new medical school. Methods This was a cross-sectional study conducted of the medical students of Universiti Sultan Zainal Abidin. The study population was 468 preclinical medical students from years 1 and 2 of academic year 2012–2013. Data were collected using a validated instrument. There were six different sections of questions using a 5-point Likert scale. The data were then compiled and analyzed, using SPSS version 20. Results The response rate was 73%. Among 341 respondents, 30% were male and 70% were female. Eighty-five percent of respondents agree or strongly agree that the lectures had met the criteria with regard to organization of lecture materials. Similarly, 97% of students agree or strongly agree that lecturers maintained adequate voices and gestures. Conclusion Medical students are quite satisfied with the lecture classes and the lectures. However, further research is required to identify student-centered teaching and learning methods to promote active learning. PMID:25878516

Didactic lecture is the oldest and most commonly used method of teaching. In addition, it is considered one of the most efficient ways to disseminate theories, ideas, and facts. Many critics feel that lectures are an obsolete method to use when students need to perform hands-on activities, which is an everyday need in the study of medicine. This study evaluates students' perceptions regarding lecture quality in a new medical school. This was a cross-sectional study conducted of the medical students of Universiti Sultan Zainal Abidin.

The introduction of PowerPoint presentation software has generated a paradigm shift in the delivery of lectures. PowerPoint has now almost entirely replaced chalkboard or whiteboard teaching at the undergraduate and graduate levels. This study investigated whether undergraduate biology students preferred to have lectures delivered by PowerPoint or written on the board as well as the reasons behind their preference. Two upper-division physiology courses were surveyed over a period of 7 yr. A total of 1,905 students (86.7%) indicated they preferred lectures delivered by "writing on the board" compared to 291 students (13.3%) who preferred PowerPoint. Common themes drawn from explanations reported by students in favor of writing on the board included: 1) more appropriate pace, 2) facilitation of note taking, and 3) greater alertness and attention. Common themes in favor of PowerPoint included 1) increased convenience, 2) focus on listening, and 3) more accurate and readable notes. Based on the students' very strong preference for writing on the board and the themes supporting that preference, we recommend that instructors incorporate elements of the writing on the board delivery style into whatever teaching modality is used. If instructors plan to use PowerPoint, the presentation should be paced, constructed, and delivered to provide the benefits of lectures written on the board. The advantages of writing on the board can be also incorporated into instruction intended to occur outside the classroom, such as animated narrated videos as part of the flipped classroom approach.

PDF Lecture Materials for Online and ``Flipped'' Format Astronomy Courses

NASA Astrophysics Data System (ADS)

Kary, D. M.; Eisberg, J.

2013-04-01

Online astronomy courses typically rely on students reading the textbook and/or a set of text-based lecture notes to replace the “lecture” material. However, many of our students report that this is much less engaging than in-person lectures, especially given the amount of interactive work such as “think-pair-share” problems done in many astronomy classes. Students have similarly criticized direct lecture-capture. To address this, we have developed a set of PowerPoint-style presentations with embedded lecture audio combined with prompts for student interaction including think-pair-share questions. These are formatted PDF packages that can be used on a range of different computers using free software. The presentations are first developed using Microsoft PowerPoint software. Audio recordings of scripted lectures are then synchronized with the presentations and the entire package is converted to PDF using Adobe Presenter. This approach combines the ease of editing that PowerPoint provides along with the platform-independence of PDF. It's easy to add, remove, or edit individual slides as needed, and PowerPoint supports internal links so that think-pair-share questions can be inserted with links to feedback based on the answers selected. Modern PDF files support animated visuals with synchronized audio and they can be read using widely available free software. Using these files students in an online course can get many of the benefits of seeing and hearing the course material presented in an in-person lecture format. Students needing extra help in traditional lecture classes can use these presentations to help review the materials covered in lecture. Finally, the presentations can be used in a “flipped” format in which students work through the presentations outside of class time while spending the “lecture” time on in-class interaction.

Commentary: IDSA guidelines for improving the teaching of preclinical medical microbiology and infectious diseases.

Preclinical microbiology and infectious diseases courses too often primarily depend on PowerPoint lectures and notes, combined with multiple-choice tests, as their primary teaching tools. This strategy sets low expectations for students, encouraging short-term memory and discouraging understanding and long-term memory. These methods also fail to stimulate active participation, collaborative learning, and two-way communication with the professor, and they do not respect the students' diverse talents and ways of learning. The Infectious Diseases Society of America Preclinical Curriculum Committee proposes a new approach that emphasizes active learning and understanding and that addresses all of these failures. It consists of five components: (1) "Just-in-time" teaching that requires students to e-mail the answers to two general questions as well as any areas of misunderstanding to the instructor several hours before each lecture, (2) peer instruction or large-group sessions consisting of student teams of four who electronically answer a conceptual question before each major section of the lecture, (3) teaching from edited textbooks and Internet sources, (4) small-group discussions that emphasize pathogenesis and differential diagnosis, and (5) essay questions that encourage and test understanding in addition to recognition. A national consensus on factual content is proposed, with the goals of reducing information overload and minimizing requirements for excessive memorization. These strategies promise to enhance learning and rekindle interest in the field of infectious diseases. Other subspecialty organizations should create similar teaching guidelines that will encourage future medical students to bring a richer understanding of clinical and basic science to the bedside.

We describe Interactive Lecture Experiments (ILE), which build on Interactive Lecture Demonstrations proposed by Sokoloff and Thornton (2004) and extends it by providing students with the opportunity to analyze experiments demonstrated in the lecture outside of the classroom. Real time experimental data is collected, using Logger Pro combined with the digital video technology. This data is uploaded to the Internet and made available to the students for further analysis. Student learning is assessed in the following lecture using conceptual questions (clickers). The goal of this project is to use ILE to make large lectures more interactive and promote student interest in science, critical thinking and data analysis skills. We report on the systematic study conducted using the Colorado Learning Attitudes about Science Survey, Force Concept Inventory, open-ended physics problems and focus group interviews to determine the impact of ILE on student academic achievement, motivation and attitudes towards physics. Three sections of students (750 students) experienced four ILE experiments. The surveys were administered twice and academic results for students who experienced the ILE for a particular topic were compared to the students, from a different section, who did not complete the ILE for that topic. Additional qualitative data on students’ attitudes was collected using open ended survey questions and interviews. We will present preliminary conclusions about the role of ILEs as an effective pedagogy in large introductory physics courses. Sokoloff, D.R. and R.K. Thornton (2004).

A study was designed to assess the impact of a wireless technology known as an audience response system (ARS), commonly known clickers, on learning and student engagement in a nursing classroom. Students in the control group responded verbally to questions posed during lectures, while students in the intervention groups responded anonymously using the ARS. Although no significant improvement in postlecture quizzes was noted, students in ARS-enhanced lectures reported significantly higher satisfaction scores. The use of ARS promoted a sense of comfort, encouraged participation, and motivated students to answer questions and interact with the subject matter.

Does the Room Matter? Active Learning in Traditional and Enhanced Lecture Spaces

Stoltzfus, Jon R.; Libarkin, Julie

2016-01-01

SCALE-UP–type classrooms, originating with the Student-Centered Active Learning Environment with Upside-down Pedagogies project, are designed to facilitate active learning by maximizing opportunities for interactions between students and embedding technology in the classroom. Positive impacts when active learning replaces lecture are well documented, both in traditional lecture halls and SCALE-UP–type classrooms. However, few studies have carefully analyzed student outcomes when comparable active learning–based instruction takes place in a traditional lecture hall and a SCALE-UP–type classroom. Using a quasi-experimental design, we compared student perceptions and performance between sections of a nonmajors biology course, one taught in a traditional lecture hall and one taught in a SCALE-UP–type classroom. Instruction in both sections followed a flipped model that relied heavily on cooperative learning and was as identical as possible given the infrastructure differences between classrooms. Results showed that students in both sections thought that SCALE-UP infrastructure would enhance performance. However, measures of actual student performance showed no difference between the two sections. We conclude that, while SCALE-UP–type classrooms may facilitate implementation of active learning, it is the active learning and not the SCALE-UP infrastructure that enhances student performance. As a consequence, we suggest that institutions can modify existing classrooms to enhance student engagement without incorporating expensive technology. PMID:27909018

Student Success in Face-to-Face and Online Sections of Biology Courses at a Community College in East Tennessee

NASA Astrophysics Data System (ADS)

Garman, Deanna Essington

The purpose of this quantitative study was to determine if there were significant differences in student success in face-to-face and online biology courses as categorized by gender, major, and age; and as measured by lecture grades, lab grades, and final course grades. The data used for analyses included data from 170 face-to-face sections and 127 online sections from a biology course during the fall and spring semesters beginning fall 2008 through spring 2011. Researchers have reported mixed findings in previous studies juxtaposing online and face-to-face course delivery formats, from no significant differences to differences in grades, learning styles, and satisfaction levels. Four research questions guided this study with data analysis involving t-tests for independent groups and chi-square tests. This researcher noted significant differences in the results of this study: grades, success rates by gender, success rates by health and nonhealth majors, and nontraditional age (≥25) success rate were higher for students in the face-to-face courses; and the attrition rate was higher for students in the online course sections. There was no significant difference found in the success rate for traditional age (<25) students in the face-to-face sections compared to those in the online sections.

Slide shows vs graphic tablet live drawing for anatomy teaching.

PubMed

Alsaid, B

2016-12-01

Blackboard drawing is the traditional and still widely learned method for anatomy teachers. However, for practical reasons, more and more lessons are done using slide shows. New digital learning tools are developed to create a more attractive teaching method. The objective of this study was to compare the use of graphic tablet live drawing versus slide shows. Sixty-five second-year students of the Faculty of Medicine participated in this study during their first semester of 2013-2014 academic year. The selected lecture dealt about neuroanatomy; two brain sections were taught: median sagittal and transverse. The sagittal section was presented via a slide show. The transverse section was taught using a graphics tablet using drawing software. Students were evaluated three times: before the lecture, immediately after the lecture and 8 weeks later. Means were compared using a t-test. Scores were significantly higher immediately after the lecture and 8 weeks later tests in comparing the transverse section (using the graphics tablet) versus the sagittal section (using PowerPoint ® ). Student satisfaction regarding the use of the tablet was high. The graphics tablet is a usable and efficient drawing tool in anatomy teaching. This tool requires a specific teacher training and preparation. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

2016-01-01

Teachers often wonder what students are doing during lectures, behind their computers, mobile phones and other digital tools. This study aimed to document the type of tools used during lectures by nursing students and what they do with them. We carried out a descriptive, prospective, multicentre study including 1446 nursing students in Alsace (France). The students filled in an anonymous questionnaire at the end of a lesson they had just attended. 99% of the students had taken at least one digital tool to the lesson. 90% had a mobile phone with them. It was mainly used for entertainment (particularly for sending and/or receiving text messages and consulting emails). 52% had a laptop with them. It was essentially used for academic tasks (taking notes, working on other teaching units or revising for exams). Most nursing students take a phone or laptop to lectures with them with the intention of using them for entertainment and learning respectively. These results could guide training establishments in drafting their institutional policy concerning the use of digital tools in class.

['Anatomia actuosa et apta'. The mechanist 'proto'-physiology of B.S. Albinus].

PubMed

van der Korst, J K

1993-01-01

Already during his tenure as professor of anatomy and surgery (1721-1746) and before he became a professor of physiology and medicine at the University of Leiden, Bernard Siegfried Albinus held private lecture courses on physiology. In these lectures he pleaded for a separation of physiology from theoretical medicine, which was still its customary place in the medical curriculum of the first half of the eighteenth century. According to Albinus, physiology was a science in its own right and should be solely based on the careful observation of forms and structures of the human body. From the 'fabrica', the function ('aptitudo') could be derived by careful reasoning. As shown by a set of lecture notes, which recently came to light, Albinus adhered, initially, to a strictly mechanistic explanatory model, which was almost completely based on the physiological concepts of Herman Boerhaave. However, in contrast to the latter, he even rejected the involvement of chemical processes in digestion. Although his lectures were highly acclaimed as demonstrations of minute anatomy, Albinus met with little or no direct response in regard to his concept of physiology.

The influence of podcasting on student learning: a case study across two courses

NASA Astrophysics Data System (ADS)

Collier-Reed, Brandon I.; Case, Jennifer M.; Stott, Angela

2013-06-01

There is a growing literature on the educational benefits of using podcasting of lectures in higher education, but to date little research that interrogates closely its impact on student learning. The present study investigated how students used lecture podcasts produced in two engineering courses at a South African university. The findings confirm much of the growing consensus in the literature. Firstly, a majority of students in the courses elected to use the podcasts. Secondly, the study notes that lecture attendance, in contexts where lectures are seen as beneficial, is not adversely affected. Thirdly, few students use podcasts in the mobile mode but most rather use them as an additional resource in their private study spaces. There is intense use in the build up to tests and examinations, and there is a particular benefit for students who are not first language speakers of the medium of instruction. This study also points to the existence of both deep and surface approaches to engaging with podcasts, with substantial evidence of many students using podcasts as a means towards better understanding.

Amount and distribution of study in a personalized instruction course and in a lecture course1

The rapid proliferation of courses based on Keller's Personalized System of Instruction (PSI) calls for a prompt evaluation of the relative costs involved in PSI and more traditional forms of college instruction. To determine the cost in student time required by a course taught with PSI relative to lecture, students did their studying in a special Study Center where course materials could be used but not removed. Students in the PSI section spent an average of about 50% more time in the Study Center (46 hr) than did students in the lecture section (30 hr), but that difference was made up by the lecture students spending an average of 20 hr attending lectures. Thus, total preparation time was about the same. PSI students scored slightly higher on common course exams, and while college entrance exam scores correlated highly with course exam scores, Study Center time was reliably related to course exam score only for PSI students. An analysis of the study records of individual students revealed that PSI produced fairly regular patterns of study by all students, while lecture students varied greatly in their patterns.

Hand-waving and interpretive dance: an introductory course on tensor networks

NASA Astrophysics Data System (ADS)

Bridgeman, Jacob C.; Chubb, Christopher T.

2017-06-01

The curse of dimensionality associated with the Hilbert space of spin systems provides a significant obstruction to the study of condensed matter systems. Tensor networks have proven an important tool in attempting to overcome this difficulty in both the numerical and analytic regimes. These notes form the basis for a seven lecture course, introducing the basics of a range of common tensor networks and algorithms. In particular, we cover: introductory tensor network notation, applications to quantum information, basic properties of matrix product states, a classification of quantum phases using tensor networks, algorithms for finding matrix product states, basic properties of projected entangled pair states, and multiscale entanglement renormalisation ansatz states. The lectures are intended to be generally accessible, although the relevance of many of the examples may be lost on students without a background in many-body physics/quantum information. For each lecture, several problems are given, with worked solutions in an ancillary file.

The Historical Origins of Spacetime

NASA Astrophysics Data System (ADS)

Walter, Scott

The idea of spacetime investigated in this chapter, with a view toward understanding its immediate sources and development, is the one formulated and proposed by Hermann Minkowski in 1908. Until recently, the principle source used to form historical narratives of Minkowski's discovery of spacetime has been Minkowski's own discovery account, outlined in the lecture he delivered in Cologne, entitled Space and time [1]. Minkowski's lecture is usually considered as a bona fide first-person narrative of lived events. According to this received view, spacetime was a natural outgrowth of Felix Klein's successful project to promote the study of geometries via their characteristic groups of transformations. Or as Minkowski expressed the same basic thought himself, the theory of relativity discovered by physicists in 1905 could just as well have been proposed by some late-nineteenth-century mathematician, by simply reflecting upon the groups of transformations that left invariant the form of the equation of a propagating light wave. Minkowski's publications and research notes provide a contrasting picture of the discovery of spacetime, in which group theory plays no direct part. In order to relate the steps of Minkowski's discovery, we begin with an account of Poincaré's theory of gravitation, where Minkowski found some of the germs of spacetime. Poincaré's geometric interpretation of the Lorentz transformation is examined, along with his reasons for not pursuing a four-dimensional vector calculus. In the second section, Minkowski's discovery and presentation of the notion of a world line in spacetime is presented. In the third and final section, Poincaré's and Minkowski's diagrammatic interpretations of the Lorentz transformation are compared.

Note taking, review, memory, and comprehension.

In previous work assessing memory at various levels of representation, namely the surface form, textbase, and situation model levels, participants read texts but were otherwise not actively engaged with the texts. The current study tested the influence of active engagement with the material via note taking, along with the opportunity to review such notes, and the modality of presentation (text vs. spoken). The influence of these manipulations was assessed both immediately and 1 week later. In Experiment 1 participants read a text, whereas in Experiment 2 participants watched a video recording of the material being read as a lecture. For each experiment the opportunity to take notes was manipulated within participants, and the opportunity to review these notes before the test was manipulated between participants. Note taking improved performance at the situation model level in both experiments, although there was also some suggestion of benefit for the surface form. Thus, active engagement with material, such as note taking, appears to have the greatest benefit at the deeper levels of understanding.

A research and nursing development initiative group consisting of health lecturers and lecturer practitioners set out to evaluate how learners and teachers felt about the introduction of an enquiry based learning (EBL) approach to education. Five focus groups, teachers (1 group) post-registration students (1 group) and pre-registration diploma students (3 groups) were interviewed. Discussions were tape recorded, transcribed, and analysed. The results revealed that students and teachers held disparative views on the efficiency of EBL. Teachers, surprisingly, felt more doubtful and discouraged than learners. Several concerns were raised over the ability of EBL to establish a foothold in a curriculum more noted for a pedagogical stance on learning.

Live lecture versus video-recorded lecture: are students voting with their feet?

PubMed

Cardall, Scott; Krupat, Edward; Ulrich, Michael

2008-12-01

In light of educators' concerns that lecture attendance in medical school has declined, the authors sought to assess students' perceptions, evaluations, and motivations concerning live lectures compared with accelerated, video-recorded lectures viewed online. The authors performed a cross-sectional survey study of all first- and second-year students at Harvard Medical School. Respondents answered questions regarding their lecture attendance; use of class and personal time; use of accelerated, video-recorded lectures; and reasons for viewing video-recorded and live lectures. Other questions asked students to compare how well live and video-recorded lectures satisfied learning goals. Of the 353 students who received questionnaires, 204 (58%) returned responses. Collectively, students indicated watching 57.2% of lectures live, 29.4% recorded, and 3.8% using both methods. All students have watched recorded lectures, and most (88.5%) have used video-accelerating technologies. When using accelerated, video-recorded lecture as opposed to attending lecture, students felt they were more likely to increase their speed of knowledge acquisition (79.3% of students), look up additional information (67.7%), stay focused (64.8%), and learn more (63.7%). Live attendance remains the predominant method for viewing lectures. However, students find accelerated, video-recorded lectures equally or more valuable. Although educators may be uncomfortable with the fundamental change in the learning process represented by video-recorded lecture use, students' responses indicate that their decisions to attend lectures or view recorded lectures are motivated primarily by a desire to satisfy their professional goals. A challenge remains for educators to incorporate technologies students find useful while creating an interactive learning culture.

2015-08-01

At our hospital, intending to obtaining an approval from the Joint Commission International (JCI), we conducted a workshop on sedation for all staff physicians. A sedation instructor authorized by the Japanese Association for Medical Simulation gave a lecture using the "practice guidelines for sedation and administration of analgesics for non-anesthesiologists", revised in 2002 by the American Society of Anesthesiologists, following which, a test using 10 true-false questions was conducted, while before and after the lecture a questionnaire survey on the sedation lecture was carried out Among 191 physicians attending the lecture, except for one person, 7 or more questions were answered correctly. From the questionnaires, the sedation lectures were also generally accepted favourably. In the test of understanding, the mistakes were mostly in the sections on "sedation evaluation" "intraoperative monitoring" "pharmaceutical knowledge" and "airway management methods". The sedation lecture in the hospital was effective.

Although the flipped classroom model has been widely adopted in medical education, reports on its use in graduate-level public health programs are limited. This study describes the design, implementation, and evaluation of a flipped classroom redesign of an introductory epidemiology course and compares it to a traditional model. One hundred fifty Masters-level students enrolled in an introductory epidemiology course with a traditional format (in-person lecture and discussion section, at-home assignment; 2015, N = 72) and a flipped classroom format (at-home lecture, in-person discussion section and assignment; 2016, N = 78). Using mixed methods, we compared student characteristics, examination scores, and end-of-course evaluations of the 2016 flipped classroom format and the 2015 traditional format. Data on the flipped classroom format, including pre- and post-course surveys, open-ended questions, self-reports of section leader teaching practices, and classroom observations, were evaluated. There were no statistically significant differences in examination scores or students' assessment of the course between 2015 (traditional) and 2016 (flipped). In 2016, 57.1% (36) of respondents to the end-of-course evaluation found watching video lectures at home to have a positive impact on their time management. Open-ended survey responses indicated a number of strengths of the flipped classroom approach, including the freedom to watch pre-recorded lectures at any time and the ability of section leaders to clarify targeted concepts. Suggestions for improvement focused on ways to increase regular interaction with lecturers. There was no significant difference in students' performance on quantitative assessments comparing the traditional format to the flipped classroom format. The flipped format did allow for greater flexibility and applied learning opportunities at home and during discussion sections.

A comparison of traditional and engaging lecture methods in a large, professional-level course.

Miller, Cynthia J; McNear, Jacquee; Metz, Michael J

In engaging lectures, also referred to as broken or interactive lectures, students are given short periods of lecture followed by "breaks" that can consist of 1-min papers, problem sets, brainstorming sessions, or open discussion. While many studies have shown positive effects when engaging lectures are used in undergraduate settings, the literature surrounding use of the learning technique for professional students is inconclusive. The novelty of this study design allowed a direct comparison of engaging physiology lectures versus didactic lecture formats in the same cohort of 120 first-year School of Dentistry DMD students. All students were taught five physiological systems using traditional lecture methods and six physiological systems using engaging lecture methods. The use of engaging lectures led to a statistically significant higher average on unit exams compared with traditional didactic lectures (8.6% higher, P < 0.05). Furthermore, students demonstrated an improved long-term retention of information via higher scores on the comprehensive final exam (22.9% higher in engaging lecture sections, P < 0.05). Many qualitative improvements were also indicated via student surveys and evaluations, including an increased perceived effectiveness of lectures, decrease in distractions during lecture, and increased confidence with the material. The development of engaging lecture activities requires a significant amount of instructor preparation and limits the time available to provide traditional lectures. However, the positive results of this study suggest the need for a restructuring of the physiology curriculum to incorporate more engaging lectures to improve both the qualitative experiences and performance levels of professional students.

General practice became an academic discipline quite recently in many western countries. In France, junior lecturer work is specified in a three-part mandate: medical work in general practice, teaching in the university, and research. Since 2007, 130 junior lecturers have been appointed in general practice. The aim of the creation of junior lecturer status was to align general practice with other specialties and to develop research and education in primary care. To describe the healthcare, teaching and research undertaken by junior lecturers in general practice, practising in October 2014. A cross-sectional multicentre study using an online self-administered questionnaire on the cohort composed of all the junior lecturers in general practice with open questions and the qualitative analysis of written verbatim accounts. Of the 95 junior lecturers practising at the date of the study, 75 (79%) responded; average age 32 years; gender ratio (F/M) 2.4:1. They spent five, two and three half-days per week respectively in healthcare, teaching and research. The healthcare activity was predominantly carried out in the community (73%). Thirty-nine per cent worked as part of a multi-professional team taking on 50 consultations per week. Most of the educational work involved lecturing and mentoring students specializing in general practice (median 86 hours per year). Research output increased during the fellowship. Research topics were varied and relevant to the disciplinary field. During the fellowship, the balancing, and even the reinforcement, of healthcare and research contributions were accompanied by a significant investment in educational provision.

This study was conducted to identify lecture strategy and teaching aid best suited for North Indian dental and medical students. It was conducted in two parts - 1. Survey of teachers' and students' opinion to obtain their preferences in teaching-learning practices followed in a conventional lecture, and 2. Comparison of students' performances after a single trial lecture with different groups of students, using different teaching aids (TAs). Opinions of 33 faculty teaching first year dental/ medical students and 506 volunteer students (320 female) were compiled. Students were divided into four groups. A single trial lecture was held with each group (on the same topic, using identical lesson plan, by the same teacher) using a different teaching aid with each group. Lecture strategy was designed according to students' preferences (as obtained from opinion survey) regarding language of instruction and the number of mental breaks. TAs used with different groups were chalk and board (C&B), PowerPoint (PPT), overhead projector (OHP), and a combination of C&B and PPT. Pre- and post-tests using multiple choice questions were conducted with each group. RESULTS of post-test questionnaire and feedback from faculty attending the lecture were assessed for students' satisfaction and attentiveness in all four groups. Survey results indicated that although 97.6% students believed they had good/fair proficiency in English, 83.6% preferred being taught in a combination of English and Hindi; 44.3% students preferred C&B, 40.1% preferred PPT and 15.6% preferred the use of OHP as TA. After conducting a trial lecture with different TAs with each group, more than 90% students expressed satisfaction with the TA used for that group. Significantly better performance was observed in the post-lecture test when C&B was used. The needs of students in India are different from those of their Western counterparts, and should be considered during didactic lectures to improve the students' understanding. Post-test results were better when C&B was used, as more students were attentive and/or took notes.

The Progression of Podcasting/Vodcasting in a Technical Physics Class

2010-11-01

Technology such as Microsoft PowerPoint presentations, clickers, podcasting, and learning management suites is becoming prevalent in classrooms. Instructors are using these media in both large lecture hall settings and small classrooms with just a handful of students. Traditionally, each of these media is instructor driven. For instance, podcasting (audio recordings) provided my technical physics course with supplemental notes to accompany a traditional algebra-based physics lecture. Podcasting is an ideal tool for this mode of instruction, but podcasting/vodcasting is also an ideal technique for student projects and student-driven learning. I present here the various podcasting/vodcasting projects my students and I have undertaken over the last few years.

An Introduction to the Gas Phase

Vallance, Claire

2017-11-01

'An Introduction to the Gas Phase' is adapted from a set of lecture notes for a core first year lecture course in physical chemistry taught at the University of Oxford. The book is intended to give a relatively concise introduction to the gas phase at a level suitable for any undergraduate scientist. After defining the gas phase, properties of gases such as temperature, pressure, and volume are discussed. The relationships between these properties are explained at a molecular level, and simple models are introduced that allow the various gas laws to be derived from first principles. Finally, the collisional behaviour of gases is used to explain a number of gas-phase phenomena, such as effusion, diffusion, and thermal conductivity.

This study was undertaken as part of a larger programme of research; the Leadership in Compassionate Care Programme. The aim of this study was to explore and respond to the perceptions of nurse lecturers in regard to experiences of compassion in the workplace. A participatory action research approach was adopted. The study took place in a large school of nursing and midwifery in the United Kingdom, eight lecturers participated in this study. A series of four facilitated reflective workshops titled a restorative space were provided and participants used the medium of collage as a process for reflection. Data was gathered in the form of collages, field and reflective notes. Data analysis involved an iterative process between facilitators and participants during the workshops and resulting actions were implemented. Findings from this study identified three key themes related to compassion in the workplace; leadership, culture, professional and personal development. Actions identified and implemented as a consequence of these findings included opportunities for lecturers to participate in a leadership development programme and implementing rapid feedback processes between lecturers and the senior management team. The restorative space workshops and utilisation of the creative medium of collage provided a valuable process for practitioners to collaboratively reflect on their workplace experiences.

Pebay, Philippe Pierre

2004-02-01

This brief Introduction to Measure Theory, and its applications to Probabilities, corresponds to the lecture notes of a seminar series given at Sandia National Laboratories in Livermore, during the spring of 2003. The goal of these seminars was to provide a minimal background to Computational Combustion scientists interested in using more advanced stochastic concepts and methods, e.g., in the context of uncertainty quantification. Indeed, most mechanical engineering curricula do not provide students with formal training in the field of probability, and even in less in measure theory. However, stochastic methods have been used more and more extensively in the pastmore » decade, and have provided more successful computational tools. Scientists at the Combustion Research Facility of Sandia National Laboratories have been using computational stochastic methods for years. Addressing more and more complex applications, and facing difficult problems that arose in applications showed the need for a better understanding of theoretical foundations. This is why the seminar series was launched, and these notes summarize most of the concepts which have been discussed. The goal of the seminars was to bring a group of mechanical engineers and computational combustion scientists to a full understanding of N. WIENER'S polynomial chaos theory. Therefore, these lectures notes are built along those lines, and are not intended to be exhaustive. In particular, the author welcomes any comments or criticisms.« less

Audience response systems (ARS) have not been used to gauge knowledge transfer and retention in the setting of large medical conferences. In this study, we explore the utility of an ARS as an educational tool in the setting of a large urology conference. At the 2011 joint meeting of the Mid-Atlantic and New England sections of the American Urological Association, conference attendees were able to use a web-based and cell-phone accessed ARS. At the meeting, six ARS questions were asked during five point-counterpoint debate topics covering areas of prostate cancer, incontinence, pediatrics, stone disease, and renal cancer. Questions were presented by expert representatives from each of the sections; questions were structured as management options for predefined cases. At the beginning and end of each 15-minute session, attendees were asked to use the ARS to select the best management option. In five out of the six questions (83%) more than 10% of responses were changed following the presentation of the point-counterpoint session and a > 25% change in response was noted in two out of the six questions (33%). A statistically significant change was noted for one question relating to management of urolithiasis in pregnancy (p = 0.037). This is the first study which demonstrates the potential utility of an ARS in a large urology conference. With further research it may be possible to use this technology to identify high-yield topics for medical education and improve outcomes during lecture-based educational activities.

2017-01-01

Formal lectures have been a traditional part of medical and dental education, but there is debate as to their compulsory status. This study was designed to explore dental and medical students’ views on compulsory lectures and the use of Video-Recorded Lectures (VRL). A cross-sectional study of University of Bristol students in Years 2 to 4 was conducted using an online questionnaire. The majority of both dental (76%) and medical (66%) students felt lectures should be non-compulsory. The most common learning resources used by both dental and medical students were live lectures, lecture handouts and VRL. The majority of both dental (84%) and medical (88%) students used VRL. Most students attended lectures all of the time both before and after the introduction of VRL, even though most dental and medical students believe lectures should be non-compulsory. VRL is a popular learning resource. These findings tie-in with General Dental Council and General Medical Council recommendations that encourage self-directed learning. Dental and Medical schools should offer a range of learning resources and make use of current technology, including the use of VRL. PMID:29563421

An Investigation of First-Year Students' and Lecturers' Expectations of University Education

Transition from school to university can cause concern for many students. One issue is the gap between students' prior expectations and the realities of university life, which can cause significant distress, poor academic performance and increased drop-out rates if not managed effectively. Research has shown several similarities in the expectations of staff and students in regards to which factors determine academic success, but there is also evidence of dissonance. For example, staff consider independent study and critical evaluation as key factors, whereas students view feedback on drafts of work and support from staff as being most important. The aim of the current study was to determine what expectations students hold when starting university education, and what expectations university lecturers have of students entering university. Lecturers (n = 20) and first year students (n = 77) completed a series of questionnaires concerning their expectations of learning in HE (staff and students) and their approach to teaching (staff). Results revealed that students have largely realistic expectations of university. For example, the majority expected to be in charge of their own study. Some unrealistic expectations were also evident, e.g., most expected that teaching would be the same at university as it had been at school. The expectation that lecturers would provide detailed notes varied as a function of student age. Lecturers reported modifying their expectations of students and adapting their teaching approach according to year of study. Information-transmission/teacher-focused style was more common when teaching 1st year students; a more concept-changing/student-focused approach tended to be used when teaching 2nd year students (and above). Lecturer's expectations of student engagement did not differ according to year. Less experienced lecturers reported more negative expectations of student engagement than did experienced lecturers. In line with previous work, we observed overlap in expectations of staff and students, but some clear differences too. PMID:29434555

The goal of this study was to develop and evaluate a complementary cyber education program for a required pathophysiology class for nursing students. The cyber education program comprised electronic bulletin boards, correspondence material storage, an announcement section, a report submission section, reference sites, and statistics on learning rates. Twelve online lectures complemented five lectures in the classroom. To evaluate the course's educational effectiveness, we performed an online objective questionnaire and an open questionnaire survey anonymously, and compared the complementary cyber education program with traditional classroom education. The complementary cyber education program effected significant improvements in scores for importance with regard to major, clarity of goals and education plans for courses, professor readiness, preciseness and description of lectures, amount and efficiency of assignments, and fairness in appraisal standards compared with the traditional classroom education group. This study indicates that a complementary cyber education program provides nursing students with the flexibility of time and space, the newest information through updated lectures, efficient motivational aids through intimacy between the lecturer and students, and concrete and meaningful tasks. The complementary cyber education course also increased student effort toward studying and student satisfaction with the class.

Hamiltonian flows with random-walk behaviour originating from zero-sum games and fictitious play

NASA Astrophysics Data System (ADS)

van Strien, Sebastian

2011-06-01

In this paper we introduce Hamiltonian dynamics, inspired by zero-sum games (best response and fictitious play dynamics). The Hamiltonian functions we consider are continuous and piecewise affine (and of a very simple form). It follows that the corresponding Hamiltonian vector fields are discontinuous and multi-valued. Differential equations with discontinuities along a hyperplane are often called 'Filippov systems', and there is a large literature on such systems, see for example (di Bernardo et al 2008 Theory and applications Piecewise-Smooth Dynamical Systems (Applied Mathematical Sciences vol 163) (London: Springer); Kunze 2000 Non-Smooth Dynamical Systems (Lecture Notes in Mathematics vol 1744) (Berlin: Springer); Leine and Nijmeijer 2004 Dynamics and Bifurcations of Non-smooth Mechanical Systems (Lecture Notes in Applied and Computational Mechanics vol 18) (Berlin: Springer)). The special feature of the systems we consider here is that they have discontinuities along a large number of intersecting hyperplanes. Nevertheless, somewhat surprisingly, the flow corresponding to such a vector field exists, is unique and continuous. We believe that these vector fields deserve attention, because it turns out that the resulting dynamics are rather different from those found in more classically defined Hamiltonian dynamics. The vector field is extremely simple: outside codimension-one hyperplanes it is piecewise constant and so the flow phit piecewise a translation (without stationary points). Even so, the dynamics can be rather rich and complicated as a detailed study of specific examples show (see for example theorems 7.1 and 7.2 and also (Ostrovski and van Strien 2011 Regular Chaotic Dynf. 16 129-54)). In the last two sections of the paper we give some applications to game theory, and finish with posing a version of the Palis conjecture in the context of the class of non-smooth systems studied in this paper.

Does the Room Matter? Active Learning in Traditional and Enhanced Lecture Spaces.

PubMed

Stoltzfus, Jon R; Libarkin, Julie

2016-01-01

SCALE-UP-type classrooms, originating with the Student-Centered Active Learning Environment with Upside-down Pedagogies project, are designed to facilitate active learning by maximizing opportunities for interactions between students and embedding technology in the classroom. Positive impacts when active learning replaces lecture are well documented, both in traditional lecture halls and SCALE-UP-type classrooms. However, few studies have carefully analyzed student outcomes when comparable active learning-based instruction takes place in a traditional lecture hall and a SCALE-UP-type classroom. Using a quasi-experimental design, we compared student perceptions and performance between sections of a nonmajors biology course, one taught in a traditional lecture hall and one taught in a SCALE-UP-type classroom. Instruction in both sections followed a flipped model that relied heavily on cooperative learning and was as identical as possible given the infrastructure differences between classrooms. Results showed that students in both sections thought that SCALE-UP infrastructure would enhance performance. However, measures of actual student performance showed no difference between the two sections. We conclude that, while SCALE-UP-type classrooms may facilitate implementation of active learning, it is the active learning and not the SCALE-UP infrastructure that enhances student performance. As a consequence, we suggest that institutions can modify existing classrooms to enhance student engagement without incorporating expensive technology. © 2016 J. R. Stoltzfus and J. Libarkin.

Crowley, Diarmuid; Grant, Mark

2017-07-01

A Poincaré-Hopf Theorem for line fields with point singularities on orientable surfaces can be found in Hopf's 1956 Lecture Notes on Differential Geometry. In 1955 Markus presented such a theorem in all dimensions, but Markus' statement only holds in even dimensions 2 k ≥ 4. In 1984 Jänich presented a Poincaré-Hopf theorem for line fields with more complicated singularities and focussed on the complexities arising in the generalized setting. In this expository note we review the Poincaré-Hopf Theorem for line fields with point singularities, presenting a careful proof which is valid in all dimensions.

The volume of medical knowledge has increased exponentially and so has the need to improve the efficiency of current teaching practices.With increasing emphasis on interactive and problem based learning, the place of lectures in modern medical education has become a questionable issue. Objectives were to assess the perspective of undergraduate medical students regarding the role and effectiveness of lectures as a mode of instruction as well as the ways and means that can be employed to enhance the effectiveness of lectures. A cross sectional study was carried out among 2nd to final year medical students from five medical colleges including both private and public sector institutions. A total of 347 students participated by completing a structured questionnaire. Data was analyzed using SPSS-17. Sixty seven percent students considered lectures as a useful mode of instruction (47% males and 77% females), whereas 83% of the students reported that clinical sessions were superior to lectures because of small number of students in clinical sessions, active student participation, enhanced clinical orientation, and interaction with patients. About 64% responded that lectures should be replaced by clinical sessions. Majority of the students (92%) reported not being able to concentrate during a lecture beyond 30 minutes, whereas 70% skipped lectures as they were boring. A significantly greater proportion of male respondents, students from clinical years, and those who skipped lectures, considered lectures to be boring, a poor utilization of time and resources, and could not concentrate for the full duration of a lecture compared to females, students from preclinical years, and those who do not skip lectures, respectively. Lecturing techniques need to be improvised. The traditional passive mode of instruction has to be replaced with active learning and inquiry based approach to adequately utilize the time and resources spent on lectures.

A comparison of students' achievement and attitude as a function of lecture/lab sequencing in a non-science majors introductory biology course

NASA Astrophysics Data System (ADS)

Hurst March, Robin Denise

This investigation compared student achievement and attitudes toward science from three different sequencing approaches used in teaching biology to nonscience students. The three sequencing approaches were the lecture course only, lecture/laboratory courses taken together, and laboratory with previously taken lecture approach. The purposes of this study were to determine if (1) a relationship exists between the Attitude Towards Science in School Assessment (ATSSA) scores (Germann, 1988) and biology achievement, (2) a difference exists among the ATSSA scores and sequencing, (3) a difference exists among the biology achievement scores and sequencing, and (4) the ATSSA is a reliable instrument of science attitude assessment for the undergraduate students in an introductory biology nonmajors laboratory and lecture courses at a research I institution during the fall semester 1996. Fifty-four students comprised the lecture only group, 90 students comprised the lecture and laboratory taken together approach, and 23 students comprised the laboratory only approach. Research questions addressed were (1) What are the differences in student biology achievement as a function of the three different methods of instruction? (2) What are the differences in student attitude towards science as a function of the three different methods of instruction? (3) What is the relationship between post-attitude (ATSSA) and biology achievement for each of the three methods of instruction? An analysis of variance utilized the mean posttest scores on the ATSSA and mean achievement scores as the dependent variables. The independent variables were the three different sequences of enrollment in introductory biology. At the.05 level of significance, it was found that no significant difference existed between the ATTS and laboratory/lecture sequence. At the.05 level of significance, it was found that no significant difference existed between achievement and laboratory/lecture sequence. A Pearson product moment correlation was used to see if a relationship existed between posttest ATSSA scores and achievement totals in each sequence. A significant relationship was noted between the ATSSA and achievement in each sequence that involved a laboratory component.

This article describes an Internet-based instructional tool designed to give predoctoral dental students a virtual simulation of clinical pediatric dentistry to develop their pediatric behavior management knowledge. Effectiveness of this tool was evaluated using two consecutive classes of junior dental students. The control group was exposed to the traditional behavior management curriculum (two lectures) in a spring term course. The next class of dental students was exposed to the two lectures and, in addition, completed the behavior management simulation during the following spring term. Both groups completed a two-part examination (objective section=18 questions; open-ended section=responses to a clinical situation) designed to test their behavior management knowledge. The simulation group performed significantly better in both parts of the examination (objective section: p=.028; open-ended section: p=.012). The simulation was evaluated by students and perceived by most to be an effective addition to the curriculum. It was concluded that the experimental behavior management simulation, when added to the traditional lecture curriculum, improved pediatric behavior management knowledge in predoctoral dental students.

Decreased lecture attendance in undergraduate and health science professions education has been noted throughout the world. The limited study of the effect of lecture attendance on dental students' performance has yielded mixed results, with some studies finding a positive effect and others reporting no association. The aim of this study was to evaluate the effect of lecture attendance on dental students' final grades in an oral pathology course at one U.S. dental school. Due to a curriculum change, second- and third-year students (N=233) were concurrently enrolled in the spring 2016 oral pathology (OP) course. Students' course grades were compared to attendance percentage (Att), grades in prerequisite basic science (PBS) courses, and Academic Average and Total Science (TS) scores on the Dental Admission Test. The results showed that both Att (p=0.011) and TS score (p<0.001) were significant predictors of OP grade, while race, gender, and age were not. Students' grades in OP were moderately to strongly correlated with their grades in all PBS courses (p<0.001). These results suggest that lecture attendance in OP should be encouraged but viewed in light of the finding that it was not as strongly correlated as PBS course performance and was a weaker predictor than TS score. Students with lower TS scores and PBS course grades should be encouraged to use additional supports such as tutoring to improve their performance in OP.

Background and Objectives: Medical/dental colleges in Northern India cater to students with diverse backgrounds, mother tongues, levels of comprehending English, and intelligence levels. This study was conducted to identify lecture strategy and teaching aid best suited for North Indian dental and medical students. It was conducted in two parts – 1. Survey of teachers’ and students’ opinion to obtain their preferences in teaching-learning practices followed in a conventional lecture, and 2. Comparison of students’ performances after a single trial lecture with different groups of students, using different teaching aids (TAs). Materials and Methods: Opinions of 33 faculty teaching first year dental/ medical students and 506 volunteer students (320 female) were compiled. Students were divided into four groups. A single trial lecture was held with each group (on the same topic, using identical lesson plan, by the same teacher) using a different teaching aid with each group. Lecture strategy was designed according to students’ preferences (as obtained from opinion survey) regarding language of instruction and the number of mental breaks. TAs used with different groups were chalk and board (C&B), PowerPoint (PPT), overhead projector (OHP), and a combination of C&B and PPT. Pre- and post-tests using multiple choice questions were conducted with each group. Results of post-test questionnaire and feedback from faculty attending the lecture were assessed for students’ satisfaction and attentiveness in all four groups. Results: Survey results indicated that although 97.6% students believed they had good/fair proficiency in English, 83.6% preferred being taught in a combination of English and Hindi; 44.3% students preferred C&B, 40.1% preferred PPT and 15.6% preferred the use of OHP as TA. After conducting a trial lecture with different TAs with each group, more than 90% students expressed satisfaction with the TA used for that group. Significantly better performance was observed in the post-lecture test when C&B was used. Conclusion: The needs of students in India are different from those of their Western counterparts, and should be considered during didactic lectures to improve the students’ understanding. Post-test results were better when C&B was used, as more students were attentive and/or took notes. PMID:25737979

Lectures based on cardinal symptoms in undergraduate medicine - effects of evaluation-based interventions on teaching large groups

2011-01-01

Despite critical voices lectures are still an important teaching format in current medical curricula. With the curricular reform at Hamburg Medical Faculty in the year 2004, all subject specific lectures were replaced by cardinal symptom oriented lectures (LSV) in the new clinical curriculum. LSVs are taught throughout all six thematic blocks in years three to five. Since regular student evaluations after each thematic block seemed to demand improvement of the LSVs, this study was carried out using evaluations of individual LSVs by the participating students and by trained auditors (final year students and academic staff). Based on these evaluations feedback containing the individual evaluation data was given in written form to the lecturers combined with information material on planning an LSV using modern didactic techniques. In a second evaluation period, the effects of this intervention were studied. Only small improvements in the LSVs’ quality were noted regarding the level of marks achieved. When individual items were evaluated, especially the didactic quality, significant improvements were noticeable. Overall, on the basis of individual items students ranked the quality of the LSVs significantly higher than trained auditors during the first evaluation period. This effect was no longer seen after the second evaluation period. The inter rater reliability among the auditors was very good. This study shows that regular quality assurance is needed on the structural levels and for staff to accompany the process of embedding teaching formats into curricular concepts. Further investigation is needed to determine the adequate frequency of evaluation and the format of feedback to guarantee sustainable effects of the didactic quality of lectures. PMID:21818230

A comparative evaluation of teaching methods in an introductory neuroscience course for physical therapy students

NASA Astrophysics Data System (ADS)

Willett, Gilbert M.

Background and purpose. Use of computer based instruction (CBI) in physical therapy (P.T.) education is growing. P.T. educators have reported few studies regarding the effectiveness of CBI compared to lecture based instruction, and none have specifically addressed the area of neuroscience. The purpose of this study was to determine whether CBI would be a better alternative than lecture for teaching introductory neuroscience information to first year P.T. students. Subjects. This study was conducted over two years, with 28 participants in 2003 and 34 in 2004. Methods. A randomized, cross-over design was employed for this investigation. The course in which the study took place was divided into two sections with an exam after each. Both sections included 5 one hour lectures (or 5 equivalent CBI modules) and a two hour laboratory experience. Exams consisted of 30 multiple choice questions. Students in one group participated in CBI during the first half of the course and lecture during the second half. The order of participation was reversed for students in the other group. A review exam (60 multiple choice questions) was also taken by participants six months post-participation in the course. Exam scores, study time, course development costs, and student opinions regarding teaching methods were collected after each section of the course and analyzed using quantitative and qualitative methods. Results. There were no statistically significant differences in "within course" or review exam scores between participant groups based on instructional method, however, CBI taught students spent less time studying. Student opinions did not distinguish a major preference for either instruction method. Many students preferred that CBI be used as a complimentary rather than mutually exclusive instructional method. Lecture based instruction was clearly more cost effective than CBI. Conclusion. In this study, lecture based instruction was clearly the better choice of teaching method in terms of cost, but CBI was more time efficient in terms of student learning.

Lectures from the European RTN Winter School on Strings, Supergravity and Gauge Fields, CERN, 15 19 January 2007

NASA Astrophysics Data System (ADS)

Derendinger, J.-P.; Scrucca, C. A.; Uranga, A.

2007-11-01

This special issue is devoted to the proceedings of the conference 'Winter School on Strings, Supergravity and Gauge Theories', which took place at CERN, the European Centre for Nuclear Research, in Geneva, Switzerland, from the 15 to the 19 of January 2007. This event was organized in the framework of the European Mobility Research and Training Network entitled 'Constituents, Fundamental Forces and Symmetries of the Universe'. It is part of a yearly series of scientific schools, which represents what is by now a well established tradition. The previous conferences have been held at SISSA, in Trieste, Italy, in February 2005 and at CERN in January 2006. The next will again take place at CERN, in January 2008. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of several general lectures of four hours each, the notes of which are published in the present proceedings, and seven working group discussion sessions, focused on specific topics of the network research program. It was attended by approximatively 250 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress, and to the open problems, in string theory. String theory is a compelling candidate for a theory of all interactions. A basic challenge in this field is therefore to explore the connection of string theory models and the laws of physics in different realms, like high-energy particle physics, early cosmology, or physics of strongly coupled gauge theories. Concerning the exploration of string theory compactifications leading to realistic models of particle physics, one of the main obstacles in this direction is the proper understanding of supersymmetry breaking. The lecture notes by Nathan Seiberg review the realization of spontaneous breaking of supersymmetry in field theory, including recent developments via the use of meta-stable long-lived vacua. It is possible that such an understanding proves crucial in the realization of supersymmetry breaking in string theory. A second long-standing obstacle, which is being tackled with recent techniques, is moduli stabilization, namely the removal of unwanted massless scalar fields from string models. The present status of this problem, and its prospects of solution via the introduction of general sets of fluxes in the compactification space, were covered in the lectures by Brian Wecht. Application of these ideas to connect string theory to particle physics will require a good understanding of the experimental situation at the forthcoming collider LHC at CERN, and the detection tools for signals of new physics, as reviewed in the lectures by Joe Lykken (not covered in the present issue). Along a different line, the role of moduli fields in string theory is expected to provide a natural explanation of models of inflation, and thus of the origin of the cosmological evolution of our universe. The lecture notes by Cliff Burgess provide a review of big bang cosmology, inflation, and its possible explanation in terms of string theory constructions, including some of the most recent results in the field (these notes also appear in the proceedings of two other schools held in the same period). A surprising recent application of string theory is the description, via the ideas of holography and duality between string theories and gauge theories, of physical properties of quantum chromodynamics at high temperature. Indeed experimental data on the physical properties of the quark gluon plasma, produced in heavy ion collision at the RHIC experiment in Brookhaven (and soon at the LHC at CERN) can be recovered, at a semi-quantitative level, from computations in a string theory dual of the system. These applications are reviewed in the lectures by David Mateos. The conference was financially supported by the European Commission under contract MRTN-CT-2004-005104 and by CERN. It was jointly organized by the Physics Institute of the University of Neuchâtel and the Theory Unit of the Physics Division of CERN. It is a great pleasure for us to warmly thank the Theory Unit of CERN for its very kind hospitality and for the high quality of the assistance and the infrastructures that it has provided. We also acknowledge helpful administrative assistance from the Physics Institute of the University of Neuchâtel. A special acknowledgement also goes to Denis Frank, for his very valuable help in preparing the conference web pages. Group photo

This study compares the traditional live lecture to a web-based approach in the teaching of bronchoscopy and evaluates the positive and negative aspects of both methods. We developed a web-based bronchoscopy curriculum, which integrates texts, images and animations. It was applied to first-year interns, who were later administered a multiple-choice test. Another group of eight first-year interns received the traditional teaching method and the same test. The two groups were compared using the Student's t-test. The mean scores (± SD) of students who used the website were 14.63 ± 1.41 (range 13-17). The test scores of the other group had the same range, with a mean score of 14.75 ± 1. The Student's t-test showed no difference between the test results. The common positive point noted was the presence of multimedia content. The web group cited as positive the ability to review the pages, and the other one the role of the teacher. Web-based bronchoscopy education showed results similar to the traditional live lecture in effectiveness.

2009-01-01

Objectives To identify reasons for pharmacy student attendance and absenteeism in large lectures and to determine whether certain student characteristics affect student absenteeism. Methods Pharmacy students' reasons to attend and not attend 3 large lecture courses were identified. Using a Web-based survey instrument, second-year pharmacy students were asked to rate to what degree various reasons affected their decision to attend or not attend classes for 3 courses. Bivariate analyses were used to assess the relationships between student characteristics and degree of absenteeism. Results Ninety-eight students (75%) completed the survey instrument. The degree of student absenteeism differed among the 3 courses. Most student demographic characteristics examined were not related to the degree of absenteeism. Different reasons to attend and not to attend class were identified for each of the 3 courses, suggesting that attendance decisions were complex. Conclusions Respondents wanted to take their own notes and the instructor highlighted what was important to know were the top 2 common reasons for pharmacy students to attend classes. Better understanding of factors influencing student absenteeism may help pharmacy educators design effective interventions to facilitate student attendance. PMID:19777098

Medical education is always in a state of dynamic equilibrium with continuous evolution of new techniques in teaching and learning. Objective of this study is to determine medical students' perception on preferences of teaching and learning. A total of 207 medical students participated in the study. Most (73.9%) of them were males while the modal age group was 23-25 years. Majority (57.5%) of the students belong the middle socioeconomic class and 65.7% resided within the hostel. Majority of the students (48.8%) believe two hours is enough to per lecture. Among the five different teaching-learning methods investigated, use of multimedia methods was found to be most effective. There exist a statistically significant association was found only in gender with regular oral examinations (Χ2 = 4.5, df = 1, p = 0.03) and socioeconomic class with dictation of lecture notes (Χ2 = 17.9, df = 9, p = 0.03). The present day medical student will end up as a good clinician if modern techniques of teaching and communication skills of the lecturers are adopted.

Do Active Learning Approaches in Recitation Sections Improve Student Performance? A Case Study from an Introductory Mechanics Course

NASA Astrophysics Data System (ADS)

Tobin, R. G.

2018-01-01

Abundant research leaves little question that pedagogical approaches involving active student engagement with the material, and opportunities for student-to-student discussions, lead to much better learning outcomes than traditional instructor-led, expository instructional formats, in physics and in many other fields. In introductory college physics classes, some departments have departed radically from conventional lecture-recitation-laboratory course structures, but many, including my own, retain the basic format of large-group classroom sessions (lectures) supplemented by smaller-group meetings focused on problem solving (recitations) and separate laboratory meetings. Active student engagement in the lectures is encouraged through approaches such as Peer Instruction and Interactive Lecture Demonstrations, and these approaches have been demonstrably successful.

There is a constant need for developing new fragrance ingredients in the flavor and fragrance industry, as it allows perfumers to create unique and differentiating perfumes for fine as well as functional products. Among all the categories of notes used in perfume creation, amber notes are indispensible and ubiquitous in their presence in all perfumes. Not only amber notes impart high performance and substantivity to fragrances, but they are paramount in the development of classic and legendary fragrances. This article is based on the plenary lecture delivered at the flavor & fragrance 2013 conference of the German Chemical Society in Leipzig, Germany. The strategy, rationale, and the various synthetic approaches that led to the discovery of two new very powerful, woody, amber materials, Amber Xtreme(®) (1) and Trisamber(®) (2), are delineated.

Simple, but not easy - Opportunities and challenges from teachers' and students' perspectives in the 21st century of veterinary parasitology teaching.

PubMed

Strube, Christina; Raue, Katharina; Janecek, Elisabeth

2018-03-15

One of the main goals in academia is, and has been, high quality education of students to provide theoretical and practical knowledge essential for professional life. Achieving this goal is highly dependent on teaching procedures and, consequently, on a constant adaptation of teaching styles to align to technical advances and cutting-edge topics. Technical advances can strongly influence teaching and learning in the complex subject area of veterinary parasitology. Today's students are provided with extensive, digital lecture notes, and e-learning offers including virtual microscope technology to independently obtain intensified theoretical knowledge and understanding. As veterinary parasitology is also highly reliant on proficient practical skills, lectures with integrated diagnostic exercises are mandatory. Nowadays, such practical skills, such as carrying out faecal examination procedures, can be strengthened by having access to clinical skills labs. Advances such as digital lecture notes, e-learning and virtual microscopes do not only provide new, innovative opportunities, but can also comprise challenges. In this context, provision of sufficient relevant studying material may discourage students to take on responsibilities for autonomous gathering of information. Besides technical advances, 'Zeitgeist' changes are shaping teaching contents, which are progressively expanding as zoonoses are increasingly being focused on. With the aim of adopting the one-health concept, students today are expected not only to bear responsibilities for animals, but also for their owners and public health. This article will cast light on some key challenges and opportunities in modern veterinary parasitology teaching from the teachers´ and the students´ perspectives. Copyright © 2018 Elsevier B.V.

To assess the effectiveness of lectures for continuing medical education (CME) in dermatology in a global health setting and to determine provider and patient demographics of physician assistants (PAs) practicing in rural Ghana. Physician assistants from Ghana who attended dermatology lectures at the International Seminar for Physician Assistants in 2011 or 2014 were included in this study. Surveys were administered to participants to determine dermatology resource availability, commonly encountered skin diseases, and management practices. Quizzes were administered before and after CME dermatology lectures to assess short-term retention of lecture material. In all, 353 PAs participated in this study. Physician assistants reported seeing an average of 55 patients per day. The most commonly seen skin diseases were infections, with antifungals and antibiotics being the most commonly prescribed medications. Dermatology-related complaints represented 9.5% of total clinic visits. Among practicing PAs, 23.2% reported having internet access. A total of 332 PAs completed the quizzes, and a statistically significant increase in test scores was noted in postlecture quizzes. This study reinforces the importance of dermatology education for PAs practicing in rural areas of Ghana and lends insight to critical topics for dermatology curriculum development. In addition, the increase in test scores after CME sessions suggests that lectures are an effective tool for short-term retention of dermatology-related topics. Our study indicates that as the need for health workers increases globally and a paradigm shift away from the traditional physician model of care occurs, dermatology training of PAs is not only important but also achievable.

We developed a novel Internet-based blended learning programme that allows busy health care professionals to attain core competency in clinical research. This study details the educational strategies and learning outcomes of the programme. This study was conducted at Kyoto University and seven satellite campuses from September 2009 to March 2010. A total of 176 health care professionals who had never attempted to attain core competency in clinical research were enrolled. The participants were supplied with a novel programme comprising the following four strategies: online live lectures at seven satellite campuses, short examinations after each lecture, an Internet-based feedback system and an end-of-course examination. We assessed the proportion of attendance at the lectures as the main outcome. In addition, we evaluated interaction via the feedback system and scores for end-of-course examination. Of the 176 participants, 134 (76%) reported working more than 40 hours per week. The mean proportion of attendance over all 23 lectures was 82%. A total of 156 (89%) participants attended more than 60% of all lectures and were eligible for the end-of-course examination. A total of the participants accessed the feedback system 3564 times and asked 284 questions. No statistically significant differences were noted in the end-of-course scores among medical doctors, pharmacists, registered nurses and other occupations. We developed an Internet-based blended learning programme providing core competency in clinical research. Most busy health care professionals completed the programme successfully. In addition, the participants could attain the core competency effectively, regardless of their occupation. © 2011 Blackwell Publishing Ltd.

This paper is a sub-set of my lectures presented in the Accelerator Physics course (USPAS, Santa Rosa, California, January 14-25, 2008). It is based on my notes I wrote during period from 1976 to 1979 in Novosibirsk. Only few copies (in Russian) were distributed to my colleagues in Novosibirsk Institute of Nuclear Physics. The goal of these notes is a complete description starting from the arbitrary reference orbit, explicit expressions for 4-potential and accelerator Hamiltonian and finishing with parameterization with action and angle variables. To a large degree follow logic developed in Theory of Cyclic Particle Accelerators by A.A.Kolmensky andmore » A.N.Lebedev [Kolomensky], but going beyond the book in a number of directions. One of unusual feature is these notes use of matrix function and Sylvester formula for calculating matrices of arbitrary elements. Teaching the USPAS course motivated me to translate significant part of my notes into the English. I also included some introductory materials following Classical Theory of Fields by L.D. Landau and E.M. Liftsitz [Landau]. A large number of short notes covering various techniques are placed in the Appendices.« less

The effect of the flipped model on achievement in an introductory college physics course

NASA Astrophysics Data System (ADS)

Winter, Joshua Brian

The flipped or inverted classroom model is one in which the time and place for traditional lecture and homework are reversed. Traditional lecture is replaced by online videos assigned as homework. This frees up time in class to be spent with more student centered activities such as discussion based concept questions and group problem solving. While growing in popularity, research on the effectiveness of this format is sparse. In this quasi-experimental study, two sections of an introductory algebra-based college physics course were examined over a five week period. Each section was taught with either the traditional or flipped model and physics knowledge achieved was compared using independent samples t-tests on both the instructor's unit exam and the Mechanics Baseline Test pre/posttest normalized gain. Results indicated that there was no statistically significant difference between the flipped model and the traditional lecture format. Avenues for further research are discussed.

A Lab-Based, Lecture-Free General Physics Course

NASA Astrophysics Data System (ADS)

Schneider, Mark B.

1997-04-01

The past four years have seen the development of a discovery style, lecture-free, lab-based General Physics course at Grinnell College. Similar in spirit to Priscilla Laws' Workshop Physics (P. Laws, Physics Today, Dec. 1991, p. 24.), this course is a calculus- based, two-semester sequence, which is offered in parallel with more conventional lecture sections, allowing students choice of pedagogical styles. This new course is taught without a text, allowing a somewhat atypical ordering of topics and the early inclusion of a modern introduction to quantum and statistical mechanics. A complete set of laboratory materials was developed at Grinnell for this course, with activities considerably different in most cases than Laws' activities. A quick overview of the pedagogical style and topics covered will be given, and then several specific activities will be described in greater detail. The course has been shown to be a popular and viable alternative to the more conventional sections for majors and non-majors; ongoing efforts to assess the course will be described, especially those that make comparisons between this course and more conventional sections.

To explore baseline knowledge about avalanche guidelines and the Avalanche Victim Resuscitation Checklist (AVReCh) in Italy and the knowledge acquisition from a standardized lecture. Standardized lecture material discussing AVReCh was presented during 8 mountain medicine courses from November 2014 to April 2016 in different regions of Italy. To determine the knowledge acquisition from the lecture, a pre- and postlecture survey was utilized. A total of 193 surveys were analyzed. More than 50% of the participants had never participated in lectures/courses on avalanche guidelines, and less than 50% of the participants knew about the AVReCh before the lecture. The correct temporal sequence of reportable information in the basic life support section of the AVReCh was selected by 40% of the participants before the lecture and by 75% after the lecture (P<0.001). Within subgroups analysis, most groups saw significant improvement in performance (P<0.05). The selection of the correct burial time increased from 36 to 84% (P<0.05). Health care providers and mountain rescue personnel are not widely aware of avalanche guidelines. The standardized lecture significantly improved knowledge of the principles of avalanche management related to core AVReCh elements. However, the effect that this knowledge acquisition has on avalanche victim survival or adherence to the AVReCh in the field is yet to be determined. Copyright © 2017 Wilderness Medical Society.

2007-03-01

The methods for authoring and distributing course content are undergoing substantial changes due to advancement in computer technology. Paper has been the traditional method to author and distribute course content. Paper enables students to personalize content through highlighting and note taking but does not enable the incorporation of multimedia elements. Computers enable multimedia content but lack the capability of the user to personalize the content. Therefore, we investigated TK3 eBooks as a potential solution to incorporate the benefits of both paper and computer technology. The objective of our study was to assess the utility of TK3 eBooks in the context of authoring and distributing dermatology course content for use by second-year medical students at the University of Utah School of Medicine during the spring of 2004. We incorporated all dermatology course content into TK3 eBook format. TK3 eBooks enable students to personalize information through tools such as "notebook," "hiliter," "stickies," mark pages, and keyword search. Students were given the course content in both paper and eBook formats. At the conclusion of the dermatology course, students completed a questionnaire designed to evaluate the effectiveness of the eBooks compared with paper. Students perceived eBooks as an effective way to distribute course content and as a study tool. However, students preferred paper over eBooks to take notes during lecture. In conclusion, the present study demonstrated that eBooks provide a convenient method for authoring, distributing, and using course content but that students preferred paper to take notes during lecture.

Multi-Messenger Astronomy and Dark Matter

NASA Astrophysics Data System (ADS)

Bergström, Lars

This chapter presents the elaborated lecture notes on Multi-Messenger Astronomy and Dark Matter given by Lars Bergström at the 40th Saas-Fee Advanced Course on "Astrophysics at Very High Energies". One of the main problems of astrophysics and astro-particle physics is that the nature of dark matter remains unsolved. There are basically three complementary approaches to try to solve this problem. One is the detection of new particles with accelerators, the second is the observation of various types of messengers from radio waves to gamma-ray photons and neutrinos, and the third is the use of ingenious experiments for direct detection of dark matter particles. After giving an introduction to the particle universe, the author discusses the relic density of particles, basic cross sections for neutrinos and gamma-rays, supersymmetric dark matter, detection methods for neutralino dark matter, particular dark matter candidates, the status of dark matter detection, a detailled calculation on an hypothetical "Saas-Fee Wimp", primordial black holes, and gravitational waves.

Construction and evaluation of an online microbiology course for nonscience majors.

Hughes, Lee

2008-01-01

The development of web-based technologies provides a new method for course delivery. As with any new technique, evaluation is a necessary tool to determine if the method is consistent with expectations. This study describes the conversion of a nonscience majors' microbiology lecture course to online delivery and evaluates the hypothesis that the online course can be as effective as the traditional course. Course examination scores are compared between the face-to-face and online sections over a 3-year period. On all but one of the course examinations, no significant difference is found for those students in these two distinctly different course types. The success rate, as defined by those students earning grades of C or better, is high for both course types, although the traditional course success rate is slightly higher. Student evaluations of the courses are also positive, though some differences are noted. Overall, student performance in the online course is equivalent to that in the traditional course.

Autonomous Driver Based on an Intelligent System of Decision-Making.

Czubenko, Michał; Kowalczuk, Zdzisław; Ordys, Andrew

The paper presents and discusses a system ( xDriver ) which uses an Intelligent System of Decision-making (ISD) for the task of car driving. The principal subject is the implementation, simulation and testing of the ISD system described earlier in our publications (Kowalczuk and Czubenko in artificial intelligence and soft computing lecture notes in computer science, lecture notes in artificial intelligence, Springer, Berlin, 2010, 2010, In Int J Appl Math Comput Sci 21(4):621-635, 2011, In Pomiary Autom Robot 2(17):60-5, 2013) for the task of autonomous driving. The design of the whole ISD system is a result of a thorough modelling of human psychology based on an extensive literature study. Concepts somehow similar to the ISD system can be found in the literature (Muhlestein in Cognit Comput 5(1):99-105, 2012; Wiggins in Cognit Comput 4(3):306-319, 2012), but there are no reports of a system which would model the human psychology for the purpose of autonomously driving a car. The paper describes assumptions for simulation, the set of needs and reactions (characterizing the ISD system), the road model and the vehicle model, as well as presents some results of simulation. It proves that the xDriver system may behave on the road as a very inexperienced driver.

Analysis of the Astronomy Diagnostic Test

NASA Astrophysics Data System (ADS)

Brogt, Erik; Sabers, Darrell; Prather, Edward E.; Deming, Grace L.; Hufnagel, Beth; Slater, Timothy F.

Seventy undergraduate class sections were examined from the database of Astronomy Diagnostic Test (ADT) results of Deming and Hufnagel to determine if course format correlated with ADT normalized gain scores. Normalized gains were calculated for four different classroom scenarios: lecture, lecture with discussion, lecture with lab, and lecture with both lab and discussion. Statistical analysis shows that there are no significant differences in normalized gain among the self- reported classroom formats. Prerequisites related to mathematics courses did show differences in normalized gain. Of all reported course activities, only the lecture and the readings for the course correlate significantly with the normalized gain. This analysis suggests that the ADT may not have enough sensitivity to measure differences in the effectiveness of different course formats because of the wide range of topics that the ADT addresses with few questions. Different measures of gain and their biases are discussed. We argue that the use of the normalized gain is not always warranted because of its strong bias toward high pretest scores.

A key question in physics education is the effectiveness of the teaching methods. A curriculum that has been investigated at the University of Central Florida (UCF) over the last two years is the use of particular elements of The Physics Suite. Select sections of the introductory physics classes at UCF have made use of Interactive Lecture Demonstrations as part of the lecture component of the class. The laboratory component of the class has implemented the RealTime Physics curriculum, again in select sections. The remaining sections have continued with the teaching methods traditionally used. Using pre- and post-semester concept inventory tests, a student survey, student interviews, and a standard for successful completion of the course, the preliminary data indicate improved student learning.

2015-11-01

Medical educators in recent years have been using social media for more penetrance to technologically-savvy learners. The utility of using Twitter for curriculum content delivery has not been studied. We sought to determine if participation in a social media-based educational supplement would improve student performance on a test of clinical images at the end of the semester. 116 second-year medical students were enrolled in a lecture-based clinical medicine course, in which images of common clinical exam findings were presented. An additional, optional assessment was performed on Twitter. Each week, a clinical presentation and physical exam image (not covered in course lectures) were distributed via Twitter, and students were invited to guess the exam finding or diagnosis. After the completion of the course, students were asked to participate in a slideshow "quiz" with 24 clinical images, half from lecture and half from Twitter. We conducted a one-way analysis of variance to determine the effect Twitter participation had on total, Twitter-only, and lecture-only scores. Twitter participation data was collected from the end-of-course survey and was defined as submitting answers to the Twitter-only questions "all or most of the time", "about half of the time", and "little or none of the time." We found a significant difference in overall scores (p<0.001) and in Twitter-only scores (p<0.001). There was not enough evidence to conclude a significant difference in lecture-only scores (p=0.124). Students who submitted answers to Twitter "all or most of the time" or "about half the time" had significantly higher overall scores and Twitter-only scores (p<0.001 and p<0.001, respectively) than those students who only submitted answers "little or none of the time." While students retained less information from Twitter than from traditional classroom lecture, some retention was noted. Future research on social media in medical education would benefit from clear control and experimental groups in settings where quantitative use of social media could be measured. Ultimately, it is unlikely for social media to replace lecture in medical curriculum; however, there is a reasonable role for social media as an adjunct to traditional medical education.

Solving particle transport problems with the Monte Carlo method is simple - just simulate the particle behavior. The devil is in the details, however. Thesemore » lectures provide a balanced approach to the theory and practice of Monte Carlo simulation codes. The first lectures provide an overview of Monte Carlo simulation methods, covering the transport equation, random sampling, computational geometry, collision physics, and statistics. The next lectures focus on the state-of-the-art in Monte Carlo criticality simulations, covering the theory of eigenvalue calculations, convergence analysis, dominance ratio calculations, bias in Keff and tallies, bias in uncertainties, a case study of a realistic calculation, and Wielandt acceleration techniques. The remaining lectures cover advanced topics, including HTGR modeling and stochastic geometry, temperature dependence, fission energy deposition, depletion calculations, parallel calculations, and parameter studies. This portion of the class focuses on using MCNP to perform criticality calculations for reactor physics and criticality safety applications. It is an intermediate level class, intended for those with at least some familiarity with MCNP. Class examples provide hands-on experience at running the code, plotting both geometry and results, and understanding the code output. The class includes lectures & hands-on computer use for a variety of Monte Carlo calculations. Beginning MCNP users are encouraged to review LA-UR-09-00380, "Criticality Calculations with MCNP: A Primer (3nd Edition)" (available at http:// mcnp.lanl.gov under "Reference Collection") prior to the class. No Monte Carlo class can be complete without having students write their own simple Monte Carlo routines for basic random sampling, use of the random number generator, and simplified particle transport simulation.« less

Teaching practices of the undergraduate introductory biomechanics faculty: a North American survey.

Garceau, Luke R; Ebben, William P; Knudson, Duane V

2012-11-01

Instruction and assessment strategies of undergraduate introductory biomechanics instructors have yet to be comprehensively examined. The purpose of this study was to identify the current instruction and assessment practices of North American undergraduate introductory biomechanics instructors and equipment needed for effective instruction in lecture and laboratory sessions. One hundred and sixty-five respondents (age: 42.5 +/- 10.3 years) who currently teach or have taught an introductory biomechanics course in North America were recruited by electronic mail. Subjects completed a web-based survey, consisting of 60 open- and closed-ended questions. Pearson's correlation coefficients were used to assess relationships between instructor's familiarity with either the Biomechanics Concept Inventory or the NASPE Guidelines for Undergraduate Biomechanics, and instructor and course characteristics (number of years teaching, age, faculty rank, number of quizzes given, etc.) A number of variables were significantly (p < 0.05) correlated. Answers to open-ended questions were processed using content analysis, with results categorized in content areas including: instructor and course characteristics; lecture instruction; assessment and equipment; laboratory instruction; assessment and equipment; and instructor's perspectives. Many active learning strategies for lecture and laboratory instruction were identified by faculty. Limited student preparation and limited resources were noted as the instructor's most common challenges.

The original English version of the Job Content Questionnaire (JCQ) version 1.7 (revised 1997) by Robert Karasek was self-administered to 73 (response rate 58.4%) lecturers in School of Medical Sciences USM. The prevalence of job strain (defined by low decision latitude and high psychological demands) in USM was 23.3%. The risk factors of job strain in the lecturers were psychological stressors (adjusted OR 1.2, 95% CI 1.0, 1.4), created skill (adjusted OR 0.4, 95% CI 0.2, 0.8) and working in clinical-based departments (adjusted OR 18.7, 95% CI 1.6, 22.7). The prevalence of job dissatisfaction was 42.6%. Associated factors of job dissatisfaction in USM lecturers were decision authority (p < 0.001) and psychological job demand (p < 0.001). We conclude that psychological stressors and created skill were non-protective and protective, respectively, against job strain in USM lecturers. Clinical-based lecturers experienced higher job strain compared to non-clinical-based lecturers. Psychological job demand was strongly associated with job dissatisfaction, and decision authority was protective against job dissatisfaction.

In this set of lecture notes we review the mode-coupling theory of the glass transition from several perspectives. First, we derive mode-coupling equations for the description of density fluctuations from microscopic considerations with the use the Mori Zwanzig projection operator technique. We also derive schematic mode-coupling equations of a similar form from a field-theoretic perspective. We review the successes and failures of mode-coupling theory, and discuss recent advances in the applications of the theory.

Kortemeyer, Gerd

2016-10-01

The study compares the work habits of two student groups in an introductory physics course, one in traditional and one in online sections. Both groups shared the same online materials and online homework, as well as the same discussion boards and examinations, but one group in addition had traditional lectures. The groups were compared with respect to amount and frequency of access to different online course resources. It was found that with few exceptions, both groups exhibited very similar work habits. Students in the online sections more frequently accessed content pages and more frequently contributed to course discussions. It was also found that regular access of the materials throughout the week, rather than only on homework deadline nights, is a predictor of success on examinations, and that this indicator is more reliable for students in the online sections. Overall, though, the effect of traditional lectures is minimal.

An important goal of the Section on Tumors of the American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS) since its founding in 1985 has been to foster both education and research in the field of brain tumor treatment. As one means of achieving this, the Section awards a number of prizes, research grants, and named lectures at the annual meetings of the AANS and CNS. After a brief examination of similar honors that were given in recognition of pioneering work by Knapp, Cushing, and other early brain tumor researchers, the authors describe the various awards given by the AANS/CNS Section on Tumors since its founding, their philanthropic donors, and the recipients of the awards. The subsequent career of the recipients is briefly examined, in terms of the rate of full publication of award-winning abstracts and achievement of grant funding by awardees.

These forces come from the classical dilaton tadpole in generic dimensionality, internal curvature, fluxes, and branes and orientifolds as well as non-perturbative effects. The resulting (A)dS solutions of string theory make detailed predictions for microphysical entropy, whose leading behavior we exhibit on the Coulomb branch of the system. Finally, I briefly review recent developmentsmore » concerning the role of velocity-dependent effects in the dynamics of moduli.

2014-04-14

Student absenteeism is a major concern for university education worldwide. This study was conducted to determine the prevalence and causes of absenteeism among undergraduate medical and health sciences students at Hawassa University. We conducted a cross-sectional study using a pretested self-administered structured questionnaire from May-June 2013. The primary outcome indicator was self-reported absenteeism from lectures in the semester preceding the study period. The study included all regular undergraduate students who were enrolled in the University for at least one semester. The data was entered and analyzed using SPSS version 20. The association between class absenteeism and socio-demographic and behavioral correlates of absenteeism was determined by bivariate and multivariate analyses. Results were reported as crude odds ratios (COR), adjusted odds ratios (AOR) and 95% confidence intervals (CI). 1200 students consented and filled the questionnaire. Of these students, 43.7% had missed three or more lectures and 14.1% (95% CI = 12.2-16.2) missed more than 8 lectures in the preceding semester. There was a significant association between missing more than 8 lectures and age of students, chosen discipline (medicine), and social drug use. The main reasons reported for missing lectures were preparing for another examination, lack of interest, lecturer's teaching style, and availability of lecture material. At Hawassa University College of Medicine and Health Science student habits and teacher performance play a role in absenteeism from lectures. A university culture that promotes discipline and integrity especially among medical and older students discourages social drug use will likely improve motivation and attendance. Training in teaching methodologies to improve the quality and delivery of lectures should also help increase attendance.

Problem-based learning (PBL) is the most important educational innovations in the past 4 decades. The objective of the study was to compare between the preference of medical students for PBL and the preference for traditional lectures regarding learning outcomes (e.g., knowledge, attitude, and skills) gained from both methods. A cross-sectional study was conducted among medical students who studied the hybrid curriculum (PBL and traditional lectures) in King Abdulaziz University, Jeddah, in 2011. Data was collected through a pre-constructed, validated, confidentially anonymous, and self-administered questionnaire. Students' perceptions toward PBL and traditional lectures were assessed through their response to 20 statements inquired about both methods of learning using a five-point Likert scale. Descriptive and analytic statistics were performed using SPSS, version 21 (SPSS Inc, Chicago, Ill., USA). Learners preferred PBL more to traditional lectures for better linking the knowledge of basic and clinical sciences (t test=10.15, P < .001). However, no statistical significant difference (P > .05) was observed regarding the amount of basic knowledge recalled from both methods. Students preferred PBL more to lectures for better learning attitudes, skills, future outcomes, and learning satisfaction (P < .05). PBL motivates students to learn better than lecturing (P < .05). From students' opinion, the mean total skill gained from PBL (47.2 [10.6]) was much higher than that of lectures (33.0 [9.9]), and a highly statistical significant difference was observed (t test=20.9, P < .001). Students preferred PBL more to traditional lectures for improving most of learning outcome domains, especially, learning attitudes and skills. Introducing hybrid-PBL curriculum in all Saudi universities is highly recommended.

This study provides a systematic assessment of different methods of delivering radiologic teaching content (lecture, printed text, and digital content delivery) under standard conditions, enabling comparison of the effectiveness of these methods. A printed atlas of sectional anatomy was used as a standard. Digital content was developed on the basis of the printed atlas. Lecturers used both the printed and the digital content to prepare lectures. Standardized teaching material thus created was presented to second-term undergraduate students who had attended the school's anatomy course, but had not received any radiology teaching. Multiple choice examinations were used to assess the students' ability to recognize anatomical structures in known as well as unknown images. In a survey, the students' subjective experience of the learning process was assessed. No difference was seen between the groups regarding examination results. Students preferred a combination of digital media and lectures by enthusiastic teachers. The shortage of teachers requires a compromise concerning the delivery of radiologic anatomy content in a medical school setting. Based on our results, we recommend a combined approach of lecture and digital content delivery.

Dissociative conceptual and quantitative problem solving outcomes across interactive engagement and traditional format introductory physics

The existing literature indicates that interactive-engagement (IE) based general physics classes improve conceptual learning relative to more traditional lecture-oriented classrooms. Very little research, however, has examined quantitative problem-solving outcomes from IE based relative to traditional lecture-based physics classes. The present study included both pre- and post-course conceptual-learning assessments and a new quantitative physics problem-solving assessment that included three representative conservation of energy problems from a first-semester calculus-based college physics course. Scores for problem translation, plan coherence, solution execution, and evaluation of solution plausibility were extracted for each problem. Over 450 students in three IE-based sections and two traditional lecture sections taught at the same university during the same semester participated. As expected, the IE-based course produced more robust gains on a Force Concept Inventory than did the lecture course. By contrast, when the full sample was considered, gains in quantitative problem solving were significantly greater for lecture than IE-based physics; when students were matched on pre-test scores, there was still no advantage for IE-based physics on gains in quantitative problem solving. Further, the association between performance on the concept inventory and quantitative problem solving was minimal. These results highlight that improved conceptual understanding does not necessarily support improved quantitative physics problem solving, and that the instructional method appears to have less bearing on gains in quantitative problem solving than does the kinds of problems emphasized in the courses and homework and the overlap of these problems to those on the assessment.

Objective. To compare performance and preferences of students who were randomly allocated to classroom or online sections of an elective course on immunization. Methods. Students were randomly assigned to either the classroom or online section. All course activities (lectures, quizzes, case discussions, vaccine administration, and final examination) were the same for both sections, except for the delivery of lecture material. Assessment. Students were surveyed on their preferences at the beginning and end of the semester. At the end of the semester, the majority of students in the classroom group preferred classroom or blended delivery while the majority of students in the online group preferred blended or online delivery (p<0.01). Student performance was compared at the end of the semester. There was no significant difference for any of the grades in the course between the 2 sections. Conclusion. There was no difference in student performance between the classroom and online sections, suggesting that online delivery is an effective way to teach students about immunization. PMID:24954936

Lectures from the European RTN Winter School on Strings, Supergravity and Gauge Theories, CERN, 16 20 January, 2006

This special issue is devoted to the proceedings of the conference 'Winter School on Strings, Supergravity and Gauge Theories', which took place at CERN, the European Centre for Nuclear Research, in Geneva, Switzerland, from the 16 to the 20 of January 2006. This event was organized in the framework of the European Mobility Research and Training Network entitled 'Constituents, Fundamental Forces and Symmetries of the Universe'. It is part of a yearly series of scientific schools which have become a traditional rendezvous for young researchers of the community. The previous one was held at SISSA, in Trieste, Italy, in February 2005, and the next one will take place again at CERN, in January 2007. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of five general lectures of four hours each, whose notes are published in the present proceedings, and five working group discussion sessions, focused on specific topics of the network research program. It was attended by approximately 250 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress and to the open problems in string theory. String theory is expected to provide insights into the description of systems where the role of gravity is crucial. One prominent example of such systems are time-dependent backgrounds with big bang singularities, whose status in string theory is reviewed in the lecture notes by Ben Craps. In another main problem in quantum gravity, string theory gives a fascinating microscopic description of black holes and their properties. The lectures by Shiraz Minwalla review the thermal properties of black holes from their microscopic description in terms of a holographically dual large N field theory. Progress in the description of black hole microstates, and its interplay with the macroscopic description in terms of supergravity solutions via the attractor mechanism, are covered by the lectures by Atish Dabholkar and Boris Pioline. A final important mainstream topic in string theory, being a higher-dimensional theory, is its compactification to four dimensions, and the computation of four-dimensional physical properties in terms of the properties of the internal space. The lectures by Mariana Graña review recent progress in the classification of the most general supersymmetric backgrounds describing the compactified dimensions, and their role in determining the number of massless scalar moduli fields in four dimensions. The conference was financially supported by the European Commission under contract MRTN-CT-2004-005104 and by CERN. It was jointly organized by the Physics Institute of the University of Neuchâtel and the Theory Unit of the Physics Division of CERN. It is a great pleasure for us to warmly thank the Theory Unit of CERN for its very kind hospitality and for the high quality of the services and infrastructure that it has provided. We also acknowledge helpful administrative assistance from the Physics Institute of the University of Neuchâtel. Special thanks go finally to Denis Frank for his very valuable help in preparing the conference web pages, and to J Rostant, A-M Perrin and M-S Vascotto for their continuous and very reliable assistance.

Development and Evaluation of a Clinical Note Section Header Terminology

PubMed Central

Denny, Joshua C.; Miller, Randolph A.; Johnson, Kevin B.; Spickard, Anderson

2008-01-01

Clinical documentation is often expressed in natural language text, yet providers often use common organizations that segment these notes in sections, such as “history of present illness” or “physical examination.” We developed a hierarchical section header terminology, supporting mappings to LOINC and other vocabularies; it contained 1109 concepts and 4332 synonyms. Physicians evaluated it compared to LOINC and the Evaluation and Management billing schema using a randomly selected corpus of history and physical notes. Evaluated documents contained a median of 54 sections and 27 “major sections.” There were 16,196 total sections in the evaluation note corpus. The terminology contained 99.9% of the clinical sections; LOINC matched 77% of section header concepts and 20% of section header strings in those documents. The section terminology may enable better clinical note understanding and interoperability. Future development and integration into natural language processing systems is needed. PMID:18999303

This study describes the implementation and effectiveness of small-group active engagement (GAE) exercises in an introductory biology course (BSCI207) taught in a large auditorium setting. BSCI207 (Principles of Biology III—Organismal Biology) is the third introductory core course for Biological Sciences majors. In fall 2014, the instructors redesigned one section to include GAE activities to supplement lecture content. One section (n = 198) employed three lectures per week. The other section (n = 136) replaced one lecture per week with a GAE class. We explored the benefits and challenges associated with implementing GAE exercises and their relative effectiveness for unique student groups (e.g., minority students, high- and low-grade point average [GPA] students). Our findings show that undergraduates in the GAE class exhibited greater improvement in learning outcomes than undergraduates in the traditional class. Findings also indicate that high-achieving students experienced the greatest benefit from GAE activities. Some at-risk student groups (e.g., two-year transfer students) showed comparably low learning gains in the course, despite the additional support that may have been afforded by active learning. Collectively, these findings provide valuable feedback that may assist other instructors who wish to revise their courses and recommendations for institutions regarding prerequisite coursework approval policies.

2013-03-01

The purpose of this article is to describe the implementation of a team-based learning (TBL) approach in a removable denture prosthesis (RDP) module and present the results of students' performance in individual and group TBL activities and exam scores, students' experience with TBL and end of course evaluations, and faculty feedback. Course material at the College of Dentistry, University of Sharjah, United Arab Emirates, was transformed into seven conventional lectures and seven TBL sessions. Each TBL session consisted of pre-assigned reading (self-directed learning), in-class individual and group readiness tests (accountability), team problem-solving of patient RDP cases, and faculty-led class discussion (knowledge application). The course was assessed through scores from TBL session activities and course examinations, student satisfaction survey, and faculty feedback. Course grades were found to be higher using the TBL method then the traditional lecture-based method. Student evaluation data and faculty response indicated strong support for TBL as it was implemented in the course. The faculty noted a higher level of student engagement with team learning than in conventional class lecturing. TBL is an active-learning instructional strategy for courses with high student-to-faculty ratios. This approach provides regular feedback and the opportunity for students to develop higher reasoning skills.

Semi automatic indexing of PostScript files using Medical Text Indexer in medical education.

Mollah, Shamim Ara; Cimino, Christopher

2007-10-11

At Albert Einstein College of Medicine a large part of online lecture materials contain PostScript files. As the collection grows it becomes essential to create a digital library to have easy access to relevant sections of the lecture material that is full-text indexed; to create this index it is necessary to extract all the text from the document files that constitute the originals of the lectures. In this study we present a semi automatic indexing method using robust technique for extracting text from PostScript files and National Library of Medicine's Medical Text Indexer (MTI) program for indexing the text. This model can be applied to other medical schools for indexing purposes.

THE ETHICAL EDUCATION OF OPHTHALMOLOGY RESIDENTS: AN EXPERIMENT

PubMed Central

Packer, Samuel

2005-01-01

Purpose To demonstrate the effect of ethics education on a resident’s ability to answer questions that relate to moral dilemmas and on the clinical evaluations of residents by faculty. Methods The curriculum for the ethics education that was used for this study was designed by the author and consisted of 10 lectures of 1.5 hours each. Five residencies were included in the project. One residency received one lecture, two residencies received three lectures, and two residencies received 10 lectures. To evaluate the moral skills of the residents at the beginning of the course and at the end, the residents were given the Defining Issues Test (DIT-2) developed by James Rest, which involves answering standardized questions about four moral dilemmas. Faculty evaluations were completed before and after the ethics lectures were given. At the beginning of the ethics course, each resident was given a social survey that was designed to assess participation in community, religious, political, and societal activities as well as attitudes about these activities. All residents were also asked demographic information, including their age, gender, and year of residency. Results The results of the DIT-2 taken before and after the ethics lectures were compared. No correlations were found in faculty evaluations of clinical performance of the residents before and after the course (P = .052). Associations between DIT-2 scores and questions on community and religion in the social survey were noted. Conclusion The finding that the effect of an ethics course on residents’ ability to answer moral dilemmas did not achieve statistical significance should be accepted with the understanding that this was a first attempt at standardization of many variables, especially the format of the curriculum and materials used. The use of faculty evaluations to assess clinical performance needs to be standardized, and the faculty members need additional training to ensure validity of the results. The social survey was also the first attempt to assess an association between a resident’s response to moral dilemmas, attending evaluations, and residents’ opinions that relate to community, society, politics, and religion.

It is often difficult to engage nursing students and keep their interest when teaching pharmacology. This article reports on an effective change from a lecture-only approach to teaching with the use of games and case studies in a baccalaureate nursing education program. Improvements have been noted in standardized test scores and student evaluations, and students are more engaged in the learning process. Learning has been shifted from the instructor, as in the traditional classroom, and is now student focused.

Absenteeism among medical and health science undergraduate students at Hawassa University, Ethiopia

PubMed Central

2014-01-01

Background Student absenteeism is a major concern for university education worldwide. This study was conducted to determine the prevalence and causes of absenteeism among undergraduate medical and health sciences students at Hawassa University. Methods We conducted a cross-sectional study using a pretested self-administered structured questionnaire from May-June 2013. The primary outcome indicator was self-reported absenteeism from lectures in the semester preceding the study period. The study included all regular undergraduate students who were enrolled in the University for at least one semester. The data was entered and analyzed using SPSS version 20. The association between class absenteeism and socio-demographic and behavioral correlates of absenteeism was determined by bivariate and multivariate analyses. Results were reported as crude odds ratios (COR), adjusted odds ratios (AOR) and 95% confidence intervals (CI). Results 1200 students consented and filled the questionnaire. Of these students, 43.7% had missed three or more lectures and 14.1% (95% CI = 12.2-16.2) missed more than 8 lectures in the preceding semester. There was a significant association between missing more than 8 lectures and age of students, chosen discipline (medicine), and social drug use. The main reasons reported for missing lectures were preparing for another examination, lack of interest, lecturer’s teaching style, and availability of lecture material. Conclusion At Hawassa University College of Medicine and Health Science student habits and teacher performance play a role in absenteeism from lectures. A university culture that promotes discipline and integrity especially among medical and older students discourages social drug use will likely improve motivation and attendance. Training in teaching methodologies to improve the quality and delivery of lectures should also help increase attendance. PMID:24731511

Teaching the principles of health management to first year veterinary students.

PubMed

Duffield, Todd; Lissemore, Kerry; Sandals, David

2003-01-01

A course called Health Management 1 was created as part of a new DVM curriculum at the Ontario Veterinary College. This full year course was designed to introduce students to basic concepts of health management, integrating the disciplines of epidemiology, ethology, and public health in the context of selected animal industries. The course was comprised of 60 lecture hours and four two-hour laboratories. A common definition of health management, incorporating five principles, was used throughout the course, in order to reinforce the concepts and to maintain continuity between lecture blocks. Unlike in the years prior to the introduction of the new curriculum, epidemiology was presented as a tool of health management rather than as a separate discipline. To supplement the lecture and laboratory material, a Web-based resource was created and the students were required to review the appropriate section prior to each lecture block. Small quizzes, consisting of 10 questions each within WebCT, were used to stimulate self-directed learning. Overall, the course was well received by the students. The Web resources combined with the WebCT quizzes proved to be an effective method of stimulating students to prepare for lecture.

Investigating and improving introductory physics students’ understanding of symmetry and Gauss’s law

NASA Astrophysics Data System (ADS)

Li, Jing; Singh, Chandralekha

2018-01-01

We discuss an investigation of student difficulties with symmetry and Gauss’s law and how the research on students’ difficulties was used as a guide to develop a tutorial related to these topics to help students in the calculus-based introductory physics courses learn these concepts. During the development of the tutorial, we interviewed students individually at various stages of development and administered written tests in the free-response and multiple-choice formats on these concepts to learn about common student difficulties. We also obtained feedback from physics instructors who teach introductory physics courses regularly in which these concepts were covered. The students in several ‘equivalent’ sections worked on the tutorial after traditional lecture-based instruction. We discuss the performance of students on the written pre-test (administered after lecture-based instruction in relevant concepts) and post-test given after students worked on the tutorial. We find that on the pre-test, all sections of the course performed comparably regardless of the instructor. Also, on average, student performance on the post-test after working on the tutorial is significantly better than on the pre-test after lecture-based instruction. We also compare the post-test performance of introductory students in sections of the course in which the tutorial was used versus not used and find that sections in which students engaged with the tutorial outperformed those in which students did not engage with it.

Implementation of teaching on LGBT health care.

Taylor, Anna K; Condry, Hannah; Cahill, David

2018-04-01

Lesbian, gay, bisexual and transgender (LGBT) patients represent an important proportion of the population. Despite the health inequalities and barriers to health care noted within this group, there is little evidence of LGBT-focused education within medicine, dentistry or nursing. We introduced and evaluated the effect of a half-day teaching session focused on LGBT health care, delivered to year-2 students. Initial informal discussion with year-2 and year-3 students suggested that the awareness of health inequalities other than sexual health was limited, and that students had little awareness of other issues such as gender dysphoria and heterosexism. We therefore targeted these areas when developing the material. There is little evidence of LGBT-focused education within medicine, dentistry or nursing INNOVATION: The session was divided into two sections: a lecture and a workshop. The lecture provided an introduction to issues around legislation, transgender health and health inequalities, whereas the workshops involved a role-play focused on gender dysphoria, followed by small group discussions on topics such as heterosexism and sexual identity. Volunteer peer facilitators, some of whom identified as LGBT, undertook a 2-hour training session to ensure that they were comfortable with both the material and the group facilitation. Students completed a short questionnaire before and after the session. Feedback was gathered from 350 students between 2012 and 2015. Sixty-nine per cent of students rated their competency level higher after the workshop, suggesting that they felt better prepared to consult with LGBT patients. Written comments suggested that the sessions are useful for students in terms of improving awareness of health inequalities and enabling consultation skills practice in an informal environment. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

2012-01-01

There was considerable evidence that a subject’s psychological status may influence respiratory sensations and that some subjects may experience respiratory symptoms regardless of the presence of a respiratory disease. The objective of this study was to determine the association between occupational stress and respiratory symptoms among lecturers. This cross sectional study was conducted in Universiti Putra Malaysia, involved 61 lecturers from various faculties. Job Content Questionnaire (JCQ) and questionnaires based on American Thoracic Society were used to collect the data on socio-demography, stress level and respiratory symptoms. High level of occupational stress (high strain) was determined among 16 of the respondents (26.2%). Breathlessness was the common symptom experienced by the respondents. Female lecturers were significantly experienced high stress level compared to male (p=0.035). They were also significantly having more breathlessness symptom compared to male lecturer (p=0.011). Study highlighted in study population, gender plays a significant role that influenced level of occupational stress and also gender has role in resulting occupational stress level and respiratory symptoms. There was no significant association between occupational stress and respiratory symptoms. It can be concluded that this group of lecturers of Universiti Putra Malaysia did not experienced high occupational stress level. Occupational stress level was not statistically significantly associated with all respiratory symptoms being studied. PMID:23121752

Characterizing interactive engagement activities in a flipped introductory physics class

NASA Astrophysics Data System (ADS)

Wood, Anna K.; Galloway, Ross K.; Donnelly, Robyn; Hardy, Judy

2016-06-01

Interactive engagement activities are increasingly common in undergraduate physics teaching. As research efforts move beyond simply showing that interactive engagement pedagogies work towards developing an understanding of how they lead to improved learning outcomes, a detailed analysis of the way in which these activities are used in practice is needed. Our aim in this paper is to present a characterization of the type and duration of interactions, as experienced by students, that took place during two introductory physics courses (1A and 1B) at a university in the United Kingdom. Through this work, a simple framework for analyzing lectures—the framework for interactive learning in lectures (FILL), which focuses on student interactions (with the lecturer, with each other, and with the material) is proposed. The pedagogical approach is based on Peer Instruction (PI) and both courses are taught by the same lecturer. We find lecture activities can be categorized into three types: interactive (25%), vicarious interactive (20%) (involving questions to and from the lecturer), and noninteractive (55%). As expected, the majority of both interactive and vicarious interactive activities took place during PI. However, the way that interactive activities were used during non-PI sections of the lecture varied significantly between the two courses. Differences were also found in the average time spent on lecturer-student interactions (28% for 1A and 12% for 1B), although not on student-student interactions (12% and 12%) or on individual learning (10% and 7%). These results are explored in detail and the implications for future research are discussed.

Student nurse absenteeism in higher education: An argument against enforced attendance.

PubMed

Lipscomb, Martin; Snelling, Paul C

2010-08-01

Unauthorised student nurse absenteeism in higher education troubles many university lecturers. Anecdotally, absenteeism is occasionally raised as an issue by attending students who resent others "getting away" with non-attendance and some policy documents appear to suggest that attendance should be mandated. This paper argues against enforced attendance in higher education and challenges those who would mandate attendance to explain and justify their position. Drawing on a range of nursing and non-nursing material we here discuss some of the literature on attendance, absenteeism, effort or time spent in study and grade attainment. Informed by this admittedly partial review we maintain that the evidence linking grade attainment with attendance and study effort is less conclusive than intuition might initially suggest. We note that enforcing attendance apparently runs counter to important pedagogic (humanistic and androgogic) principles. We propose that responses to absenteeism cannot be separated from questions of 'harm' and we suggest that lecturers should refrain from associating non-attendance with unprofessional behaviour and poor professionalization.

Is the use of 55" LCD 3D screen practicable in large seminar to lecture hall size audiences?

NASA Astrophysics Data System (ADS)

Ilgner, Justus; Sparrer, Ingo; Westhofen, Martin

2013-03-01

Introduction: The presentation of surgical contents to undergraduate medical students can be challenging, as the surgical approach is often different from the anatomist's perspective that is reproduced in textbooks. Although there are many options to record endoscopic, microscopic as well as "open" surgical procedures, presentation of contents still can be costly and entail a loss in picture quality including depth impression. Material and methods: We presented seven stereoscopic clips of 30 seconds to minute and 20 seconds each to 64 medical students (43 female / 21 male) as part of the "sensory organs" course module in 4th year; using one 55" LCD 3D screen with line-alternating, circular polarization. Students were asked for their subjective viewing impression and about their opinion on the usefulness of 3D presentations in medical lectures. Results: 63% of students returned their questionnaires completed. The main results (multiple answers allowed) were: 70% noted that 3D presentations made complex anatomy easier to comprehend from an unknown perspective, 48% would feel better motivated to learn surgical procedures, and 38% would generally prefer a 3D lecture to a 2D lecture, while 23% would not see any advantage of 3D presentations whatsoever. Conclusion: While the screen size compared to audience size was far from ideal, it gave medical students, who had not been exposed to surgical procedures in the operating theatre yet, an impression of general approach to microsurgery and how the choice of surgical approach in relation of vital structures can minimize trauma and unwanted effects to the patient. The availability of larger screens, however, may necessitate changes in production of 3D material from the microscope camera onward.

Stochastic Geometry and Quantum Gravity: Some Rigorous Results

NASA Astrophysics Data System (ADS)

Zessin, H.

The aim of these lectures is a short introduction into some recent developments in stochastic geometry which have one of its origins in simplicial gravity theory (see Regge Nuovo Cimento 19: 558-571, 1961). The aim is to define and construct rigorously point processes on spaces of Euclidean simplices in such a way that the configurations of these simplices are simplicial complexes. The main interest then is concentrated on their curvature properties. We illustrate certain basic ideas from a mathematical point of view. An excellent representation of this area can be found in Schneider and Weil (Stochastic and Integral Geometry, Springer, Berlin, 2008. German edition: Stochastische Geometrie, Teubner, 2000). In Ambjørn et al. (Quantum Geometry Cambridge University Press, Cambridge, 1997) you find a beautiful account from the physical point of view. More recent developments in this direction can be found in Ambjørn et al. ("Quantum gravity as sum over spacetimes", Lect. Notes Phys. 807. Springer, Heidelberg, 2010). After an informal axiomatic introduction into the conceptual foundations of Regge's approach the first lecture recalls the concepts and notations used. It presents the fundamental zero-infinity law of stochastic geometry and the construction of cluster processes based on it. The second lecture presents the main mathematical object, i.e. Poisson-Delaunay surfaces possessing an intrinsic random metric structure. The third and fourth lectures discuss their ergodic behaviour and present the two-dimensional Regge model of pure simplicial quantum gravity. We terminate with the formulation of basic open problems. Proofs are given in detail only in a few cases. In general the main ideas are developed. Sufficiently complete references are given.

E-learning provides an alternative way for higher educational institutes to deliver knowledge to learners at a distance, rather than the traditional way. The aim of this study is to identify the barrier factors of e-learning programs in Hormozgan University of Medical Sciences (HUMS) in respect of the students and lecturers' point of view. A cross-sectional study based on a questionnaire was conducted among 286 of students and lecturers in the nursing, midwifery and paramedic schools of HUMS. Two hundred and eighty-six participants filled in the questionnaire: 256 students, and 30 lecturers.

-Web-based learning is a major component of distance education. -To explore Web-based applications for pathology teaching in resource-limited sub-Saharan Africa. -The participants were consultant pathologists and trainees drawn from tertiary institutions in Nigeria. They viewed the digital slides via the Leeds virtual pathology Web site, after which, interactive lectures were given via Skype (Skype Communications, Luxembourg City, Luxembourg). Questionnaires were administered via SurveyMonkey (Palo Alto, California) to all participants of 12 sessions between 2014 and 2015. -Nine consultant pathologists and 33 trainees participated in this survey. Of all respondents, 29 (69%) thought it was fairly easy to navigate the system, 11 (26.2%) thought it was easy, whereas 2 (4.8%) felt it was difficult. In addition, 26 respondents (61.9%) found it fairly easy to make a make a diagnosis, 13 (31%) thought it was easy, and 3 (7.1%) noted that it was difficult. Twenty-four respondents (57.1%) had a fairly smooth user experience, 12 (28.6%) experienced occasional crashes, whereas 6 (14.3%) reported a smooth experience. Almost all (41 of 42; 97.6%) respondents felt the pathology teaching was beneficial to their local pathology practice, and all (100%) indicated the need for additional, similar sessions. -The beneficial applications of Internet-based lectures make them a viable, cheaper, and cost-effective alternative to face-to-face lectures in our environment.

The aim of this project was to explore the feasibility and identify the issues of using mobile technologies in the assessment of health and social care students in practice settings. We report here on a case study, which took place between a University department and varied clinical settings where students were on placement. Twenty-nine student midwives and five members of lecturing staff took part in the study and were issued with PocketPCs on which to record assessment documentation including action plans and evidence of achieving performance criteria. Qualitative data were obtained from three focus groups with student midwives and individual interviews with their link lecturers and quantitative data were gathered through short questionnaires to provide simple descriptive statistics. Findings indicated that students preferred the neatness and durability of the PocketPC to the paper based format, which became worn overtime. The ability to add to notes and references as and when appropriate was welcomed. However, anxiety about losing the device or material stored within it proved to be a major constraint. Lecturing staff found that synchronising the device with the University electronic diary system was extremely useful whilst clinical staff approached the change with varying levels of acceptance or dismissal. Introducing mobile technology into the clinical setting will require a significant shift in culture and a significant level of training and support.

Flipping the Electromagnetic Theory classroom

NASA Astrophysics Data System (ADS)

Berger, Andrew J.

2017-08-01

Electromagnetic Theory is a required junior-year course for Optics majors at the University of Rochester. This foundational course gives students their first rigorous exposure to electromagnetic vector fields, dipole radiation patterns, Fresnel reflection/transmission coefficients, waveguided modes, Jones vectors, waveplates, birefringence, and the Lorentz model of refractive index. To increase the percentage of class time devoted to student-centered conceptual reasoning and instructor feedback, this course was recently "flipped". Nearly all of the mathematically-intensive derivations were converted to narrated screencasts ("Khan Academy" style) and made available to students through the course's learning management system. On average, the students were assigned two 10-15 minute videos to watch in advance of each lecture. An electronic survey after each tutorial encouraged reflection and counted towards the student's participation grade. Over the past three years, students have consistently rated the videos as being highly valuable. This presentation will discuss the technical aspects of creating tutorial videos and the educational tradeoffs of flipping a mathematically-intensive upper-level course. The most important advantage is the instructor's increased ability to identify and respond to student confusion, via activities that would consume too much time in a lecture-centered course. Several examples of such activities will be given. Two pitfalls to avoid are the temptation for the instructor not to update the videos from year to year and the tendency of students not to take lecture notes while watching the videos.

Each mother has the legal right to decide about her delivery, but this decision should be made based on scientific knowledge. Instructions during pregnancy help to choose the proper type of delivery. This study conducted aimed to compare two instructional methods of role playing and lecture on primigravida decision about type of delivery. In this single-blind clinical trial 67 primigravida, 34-36 week were selected using multi-stage sampling and assigned into two groups randomly. Decision-making (before, 2-week after, and at admission in maternity department) was tested by a questionnaire. In role-playing group, advantages and disadvantages of two type delivery were presented by role-playing in 90-min by three scenarios. In lecture group, it was also presented in a 90-min lecture. Data were analyzed by mean difference test, Fisher test, independent and paired t -test. Two groups showed a significant difference in terms of decision at admission to maternity department ( P = 0.000). 75% of lecture group and 100% of role-playing group selected normal delivery. Postintervention knowledge score in lecture group was 18 ± 5.3 and in role-playing group 17.1 ± 4.0. Percent of change in knowledge scores in two groups was significant ( P = 0.001). Participants' attitude, before and after the intervention, in both groups was significant ( P < 0.05). Mean difference of pre- and post-test in relation to two groups' knowledge and attitude scores was not significant ( P > 0.05). In this research, lecture was more effective in raising knowledge level, and role playing was more effective in raising decision to vaginal delivery and reducing elective caesarean section. It is therefore suggested to use both teaching methods altogether for pregnant women to decrease the rate of unnecessary cesarean.

To investigate medical students' perceptions of lecture and non-lecture-based instructional methods and compare preferences for use and quantity of each during preclinical training. We administered a survey to first- and second-year undergraduate medical students at the University of Alabama School of Medicine in Birmingham, Alabama, USA aimed to evaluate preferred instructional methods.  Using a cross-sectional study design, Likert scale ratings and student rankings were used to determine preferences among lecture, laboratory, team-based learning, simulation, small group case-based learning, large group case-based learning, patient presentation, and peer teaching. We calculated mean ratings for each instructional method and used chi-square tests to compare proportions of first- and second-year cohorts who ranked each in their top 5 preferred methods. Among participating students, lecture (M=3.6, SD=1.0), team based learning (M=4.2, SD=1.0), simulation (M=4.0, SD=1.0), small group case-based learning (M=3.8, SD=1.0), laboratory (M=3.6, SD=1.0), and patient presentation (M=3.8, SD=0.9) received higher scores than other instructional methods. Overall, second-year students ranked lecture lower (χ 2 (1, N=120) =16.33, p<0.0001) and patient presentation higher (χ 2 (1, N=120) =3.75, p=0.05) than first-year students. While clinically-oriented teaching methods were preferred by second-year medical students, lecture-based instruction was popular among first-year students. Results warrant further investigation to determine the ideal balance of didactic methods in undergraduate medical education, specifically curricula that employ patient-oriented instruction during the second preclinical year.

Summary Background With the increase in the adoption of electronic health records (EHR) across the US, primary care physicians are experiencing information overload. The purpose of this pilot study was to determine the information needs of primary care physicians (PCPs) as they review clinic visit notes to inform EHR display. Method Data collection was conducted with 15 primary care physicians during semi-structured interviews, including a third party observer to control bias. Physicians reviewed major sections of an artificial but typical acute and chronic care visit note to identify the note sections that were relevant to their information needs. Statistical methods used were McNemar-Mosteller’s and Cochran Q. Results Physicians identified History of Present Illness (HPI), Assessment, and Plan (A&P) as the most important sections of a visit note. In contrast, they largely judged the Review of Systems (ROS) to be superfluous. There was also a statistical difference in physicians’ highlighting among all seven major note sections in acute (p = 0.00) and chronic (p = 0.00) care visit notes. Conclusion A&P and HPI sections were most frequently identified as important which suggests that physicians may have to identify a few key sections out of a long, unnecessarily verbose visit note. ROS is viewed by doctors as mostly “not needed,” but can have relevant information. The ROS can contain information needed for patient care when other sections of the Visit note, such as the HPI, lack the relevant information. Future studies should include producing a display that provides only relevant information to increase physician efficiency at the point of care. Also, research on moving A&P to the top of visit notes instead of having A&P at the bottom of the page is needed, since those are usually the first sections physicians refer to and reviewing from top to bottom may cause cognitive load.

Attention is given to solar system cases in which chaotic solutions of Newton's equations are important, as in chaotic rotation and orbital evolution. Hyperion is noted to be tumbling chaotically; chaotic orbital evolution is suggested to be of fundamental importance to an accounting for the Kirkwood gaps in asteroid distribution and for the phase space boundary of the chaotic zone at the 3/1 mean-motion commensurability with Jupiter. In addition, chaotic trajectories in the 2/1 chaotic zone reach very high eccentricities by a route that carries them to high inclinations temporarily.

Use of On-Line Math Skills Modules in an Introductory General Education Geoscience Course at a Community College: The Importance of Integration Across Lab & Lecture Sections

NASA Astrophysics Data System (ADS)

Moosavi, S. C.

2011-12-01

The NSF sponsored on-line math skills module series The Math You Need When You Need It (TMYN) was constructed to provide math skill development and support to introductory geoscience course instructors whose students science learning is often hindered by deficiencies in critical math skills. The on-line modules give instructors a mechanism for student-centered, skill-specific math tutorials, practice exercises and assessments outside regular class time. In principle, a student deficient in a skill such as graphing, calculating a best-fit line or manipulating and quantifying a concept such as density can use the appropriate TMYN module to identify their area of weakness, focus on developing the skill using geologically relevant examples, and get feedback reflecting their mastery of the skill in an asynchronous format just as the skill becomes critical to learning in the course. The asynchronous format allows the instructor to remain focused on the geoscience content during class time without diverting all students' attention to skill remediation needed by only a subset of the population. Such a blended approach prevents the progression of the class from being slowed by the need for remediation for some students while simultaneously not leaving those students behind. The challenge to geoscience educators comes in identifying the best strategy for implementing TMYN modules in their classrooms. This presentation contrasts the effectiveness of 2 strategies for implementing TMYN in an introductory Earth System Science class taken as a general education science lab requirement by lower division students at a community college. This course is typical of many such large general education courses in that lab instruction is provided by separate educators from the primary instructor in charge of the lecture, often creating 2 parallel and only dimly connected courses in the experience of many students. In case 1, TMYN was implemented in 3 of 4 lab sections by an adjunct lab instructor while the primary instructor made no mention or use of TMYN in lecture or in the remaining lab section. In case 2, the same instructors each taught independent lecture and lab (2) sections, with TMYN being fully integrated in the course of the first instructor while not mentioned in that of the second. The strengths and weaknesses of each approach both for faculty implementation and student learning are compared with important insights into how such modules should be implemented in lecture/lab courses with separate instructors.

Influence of curriculum type on student performance in the United States Medical Licensing Examination Step 1 and Step 2 exams: problem-based learning vs. lecture-based curriculum.

PubMed

Enarson, C; Cariaga-Lo, L

2001-11-01

The results of the United States Medical Licensing Examination Step 1 and 2 examinations are reported for students enrolled in a problem-based and traditional lecture-based curricula over a seven-year period at a single institution. There were no statistically significant differences in mean scores on either examination over the seven year period as a whole. There were statistically significant main effects noted by cohort year and curricular track for both the Step 1 and 2 examinations. These results support the general, long-term effectiveness of problem-based learning with respect to basic and clinical science knowledge acquisition. This paper reports the United States Medical Licensing Examination Step 1 and Step 2 results for students enrolled in a problem-based and traditional lecture-based learning curricula over the seven-year period (1992-98) in order to evaluate the adequacy of each curriculum in supporting students learning of the basic and clinical sciences. Six hundred and eighty-nine students who took the United States Medical Licensing Examination Step 1 and 540 students who took Step 2 for the first time over the seven-year period were included in the analyses. T-test analyses were utilized to compare students' Step 1 and Step 2 performance by curriculum groups. United States Medical Licensing Examination Step 1 scores over the seven-year period were 214 for Traditional Curriculum students and 208 for Parallel Curriculum students (t-value = 1.32, P=0.21). Mean Step 2 scores over the seven-year period were 208 for Traditional Curriculum students and 206 for Parallel Curriculum students (t-value=1.08, P=0.30). Statistically significant main effects were noted by cohort year and curricular track for both the Step 1 and Step 2 examinations. The totality of experience in both groups, although differing by curricular type, may be similar enough that the comparable scores are what should be expected. These results should be reassuring to curricular planners and faculty that problem-based learning can provide students with the knowledge needed for the subsequent phases of their medical education.

A comprehensive discussion is presented concerning the phenomena characteristically treated in vortex and turbulence theory, as well as the degree of success achieved by various computation and visualization methods and theoretical models developed for vortex flow behavior prediction. Note is taken of the pioneering research conducted by F. W. Lanchester in 1893-1907, and attention is given to vortex tip and edge generation by rectangular and delta wings, the cool core effect of the Ranque-Hilsch vortex tube, the modeling of shear flows by means of vortex array methods, the classification and modelling of turbulent flows (together with a taxonomy of their calculation methods), and NASA ILLIAC IV computations of two-dimensional channel flow. Also noted are recent results concerning the boundary layer coherent structure of a flat plate at zero pressure gradient, including the regeneration structure and flow distortion and breakdown of a turbulent boundary layer.

In these notes I have given a personally flavored exposA~© of static density-functional theory (DFT). I have started from standard many-body physics at a very elementary level and then gradually introduced the basic concepts of DFT. Successively more advanced topics are added and at the end I even discuss a few not yet published theories. The discussion represents many of the personal views of the author and there is no attempt at being comprehensive. I fully realize that I am often ‘unfair’ in treating the achievements of other researchers. Many topics of standard DFT are deliberately left out like, e.g., time-dependence, excitations, and magnetic or relativistic effects. These notes represent a compilation of a series of lectures given at at the EXC!TING Summer School DFT beyond the ground state at RiksgrA~¤nsen, Sweden in June of 2003.

Georg Philip Nenter and medicine "by notes" in the 18th century.

Bonfante, Luciana; D'Angelo, Angela; Komninos, Georgios; Antonello, Augusto

2009-01-01

Even though it is true that the medical historiography of the 18th century is lacking in great scientific personalities, it is equally true that the entire century is characterized by continuous efforts to encapsulate the medical area of knowledge, acquired until then, in precise and systematic outlines, to serve the academic teaching of the subject of medicine. Georg Philip Nenter, a pupil of Georg Ernst Stahl and a professor of medicine in the University of Strasburg, could not help being influenced by that atmosphere. He added though, in our opinion, a touch of remarkable modernity. In fact his volume Fundamenta medicinae teoretico-pratica (Venice, 1735) is a wonderful collection of the notes taken during his lectures. The description of various diseases - renal diseases in particular - maintains a very systematic development of the subject through various chapters (definition, clinical manifestations, differential diagnosis, prognosis, treatment and examples of specific prescriptions), as if students were being addressed.

Pharmacists are trusted and easily accessible healthcare providers. We assessed awareness and knowledge of symptoms, etiology, and treatment of autism spectrum disorders (ASDs) among pharmacists practicing in Palestine. The pharmacists reported low familiarity with ASDs. The median score on the 12-item knowledge section was 50.0% with an interquartile range of 16.7%. Having course(s) or lecture(s) on ASDs during pharmacy degree program was significantly associated with familiarity (p value <0.001), knowledge (p value <0.001), and confidence (p value <0.05) scores. Nearly 62% of the pharmacists reported as not feeling confident enough in their ability to counsel parents about medications used for their children with ASDs and their side effects. This study revealed gaps in awareness and knowledge of ASDs among pharmacists.

Willett, Gilbert M; Sharp, J Graham; Smith, Lynette M

2008-01-01

The use of computer-based instruction (CBI) in physical therapy education is growing, but its effectiveness compared to lecture is undefined. This study compared CBI to lecture in an introductory neuroscience course for students in their first year of a 3 year professional program leading to the Doctor of Physical Therapy Degree. Twenty-eight students participated in 2003 and 34 in 2004. A randomized, cross-over design was employed. The course was divided into two sections with an exam after each. Students in one group participated in CBI during the first half of the course and lecture during the second half with the order of participation reversed for the other group. A 6 months post-course review exam was also administered. Exam scores, study time, and student opinions regarding teaching methods were collected after each half of the course. Course development costs for both teaching approaches were also documented. There were no statistically significant differences in exam scores between participant groups. CBI students spent less time studying. Student did not distinguish a major preference for either instruction method. Many students preferred that CBI be used as a complementary rather than mutually exclusive instructional method. Lecture-based instruction was much less expensive than CBI. Lecture-based instruction was more cost effective than CBI, but CBI was more time efficient in terms of student learning.

The goal of this study is to define the long-term influence of vocal hygiene education and the effectiveness of voice training in 46 students. Half of the subjects, called the trained group (n = 23), received vocal hygiene education during 1 school year and voice training during 2 school years (18 months). The other half, also 23 subjects, received neither vocal hygiene education nor voice training as such (called the untrained group). The voice training is made up of technical workshops (30 h a year in groups of 5-8 subjects) and vocal coaching in the radio and drama projects (30 h whole class). In the lectures (30 h) a theoretical background on breathing, articulation, voicing and vocal hygiene was discussed. A multidimensional test battery containing the GRBAS scale, videolaryngostroboscopy, maximum phonation time, jitter, lowest intensity, highest frequency, Dysphonia Severity Index (DSI) and Voice Handicap Index (VHI) was applied before and after 18 months to evaluate the effect of voice training over time. A questionnaire on daily habits was presented before the lectures, and after 18 months to detect the long-term effect of the lectures. The objectively measured voice quality (DSI) of the trained group improved significantly over time (p < 0.001) due to training (p = 0.008), which was not the case in the untrained group. The self-assessed VHI, on the other hand, changed over time (p < 0.001) in both groups. For the trained group the VHI changed from 18.4 to 14.4 and in the untrained group from 20.1 to 15.3. It is important to note that the VHI scores of both groups remained high. The interpretation of the results of the daily habit questionnaire is disturbing: the initial high degree of smoking, vocal abuse, stress and late meals was not influenced by the lectures or training and remained high. This study proves the positive outcome and emphasizes the need for a well-organized voice training program in future professional voice users. However, the lectures and training on vocal hygiene failed to improve voice-conserving habits. Copyright 2004 S. Karger AG, Basel

We evaluate the learning outcomes of students in large enrollment classes comparing a blended learning course format and a traditional lecture section. Blended learning, here, describes instruction that is a combination of face-to-face meeting with asynchronous online learning, resulting in reduced class time. The course, Severe and Hazardous Weather, relies heavily on graphics and animations of weather events available online, both current and archived, and thereby lends itself well to a blended format. Severe and Hazardous Weather is a popular general education requirement course at the University of Illinois with consistently high enrollments (greater than 200 students per section) and classes at capacity. Unlike many past studies, this blended learning format is applied to a large-enrollment course of approximately 100 students. Curriculum was redesigned during fall 2007 from typical lecture to the blended format. The redesign process followed best practices grounded in peer-reviewed literature on blended and online learning. We will provide a brief overview of the course structure, but focus on the evaluation of both the curriculum design and student outcomes as compared to the traditional lecture-based course. Evaluation is based on course objectives stated in the course syllabus and is conducted following best practices; the research project received University Institutional Review Board approval prior to the start of the study.

EDITORIAL: Lectures from the European RTN Winter School on Strings, Supergravity and Gauge Theories, CERN, 21 25 January 2008

This special issue is devoted to the proceedings of the conference 'RTN Winter School on Strings, Supergravity and Gauge Theories', which took place at CERN, the European Centre for Nuclear Research, in Geneva, Switzerland, on the 21 25 January 2008. This event was organized in the framework of the European Mobility Research and Training Network entitled 'Constituents, Fundamental Forces and Symmetries of the Universe'. It is part of a yearly series of scientific schools, which represents what is by now a well established tradition. The previous ones have been held at SISSA, in Trieste, Italy, in February 2005 and at CERN in January 2006. The next one will again take place at CERN, in February 2009. The school was primarily meant for young doctoral students and postdoctoral researchers working in the area of string theory. It consisted of several general lectures of four hours each, whose notes are published in the present proceedings, and five working group discussion sessions, focused on specific topics of the network research program. It was attended by approximatively 250 participants. The topics of the lectures were chosen to provide an introduction to some of the areas of recent progress, and to the open problems, in string theory. One of the most active areas in string theory in recent years is the AdS/CFT or gauge/gravity correspondence, which proposes the complete equivalence of string theory on (asymptotically) anti-de Sitter spacetimes with gauge theories. The duality relates the weak coupling regime of one system to the strongly coupled regime of the other, and is therefore very non-trivial to test beyond the supersymmetry-protected BPS sector. One of the key ideas to quantitatively match several quantities on both sides is the use of integrability, both in the gauge theory and the string side. The lecture notes by Nick Dorey provide a pedagogical introduction to the fascinating topic of integrability in AdS/CFT. On the string theory side, progress has been limited by the difficulties of quantizing the worldsheet theory in the presence of RR backgrounds. There is increasing hope that these difficulties can be overcome, using the pure spinor formulation of string theory. The lectures by Yaron Oz overview the present status of this proposal. The gauge/gravity correspondence is already leading to important insights into questions of quantum gravity, like the entropy of black holes and its interpretation in terms of microstates. These questions can be addressed in string theory, for certain classes of supersymmetric black holes. The lectures by Vijay Balasubramanian, Jan de Boer, Sheer El-Showk and Ilies Messamah review recent progress in this direction. Throughout the years, formal developments in string theory have systematically led to improved understanding on how it may relate to nature. In this respect, the lectures by Henning Samtleben describe how the formal developments on gauged supergravities can be used to describe compactification vacua in string theory, and their implications for moduli stabilization and supersymmetry breaking. Indeed, softly broken supersymmetry is one of the leading proposals to describe particle physics at the TeV energy range, as described in the lectures by Gian Giudice (not covered in this issue). This connection with TeV scale physics is most appropriate and timely, given that this energy range will shortly become experimentally accessible in the LHC at CERN. The conference was financially supported by the European Commission under contract MRTN-CT-2004-005104 and by CERN. It was jointly organized by the Physics Institute of the University of Neuchâtel and the Theory Unit of the Physics Division of CERN. It is a great pleasure for us to warmly thank the Theory Unit of CERN for its very kind hospitality and for the high quality of the assistance and the infrastructure that it has provided. We also acknowledge helpful administrative assistance from the Physics Institute of the University of Neuchâtel. Special thanks also go to Denis Frank, for his very valuable help in preparing the conference web pages. Group photo

Scaling a Survey Course in Extreme Weather

Samson, P. J.

2013-12-01

"Extreme Weather" is a survey-level course offered at the University of Michigan that is broadcast via the web and serves as a research testbed to explore best practices for large class conduct. The course has led to the creation of LectureTools, a web-based student response and note-taking system that has been shown to increase student engagement dramatically in multiple courses by giving students more opportunities to participate in class. Included in this is the capacity to pose image-based questions (see image where question was "Where would you expect winds from the south") as well as multiple choice, ordered list, free response and numerical questions. Research in this class has also explored differences in learning outcomes from those who participate remotely versus those who physically come to class and found little difference. Moreover the technologies used allow instructors to conduct class from wherever they are while the students can still answer questions and engage in class discussion from wherever they are. This presentation will use LectureTools to demonstrate its features. Attendees are encouraged to bring a mobile device to the session to participate.

It's Not the Way I Learned!

Mason, Diana S.

2003-11-01

Computer-enhanced learning as noted by Cole and Todd (5) is “somewhat less effective at the precollege level” (p 1339). Progress is slow due to a number of factors, including instructors who are resistant to change, the complexity of the subject, and the handling of chemistry laboratories. Many of our students politely go through the motions but are not actively engaged with the lesson. Simply listening to chemistry lectures may provide students with little in the way of substantial learning gains, because lectures do not necessarily actively involve students in the activity (9), yet with the incorporation of today’s technology into our curriculum and the flexible, asynchronous environment of online learning with the advantages immediate feedback provides (6) many students will expand their knowledge and skills. Careful monitoring by the instructor and setting of internal deadlines for students involved in online learning are known to encourage higher completion rates than are generally reported (10). We should take advantage of today’s advances, embrace them, and be the ones to change—set the pace and avoid the trap of “it’s not the way I learned to do it!”

Pedagogical progeniture or tactical translation? George Fordyce's additions and modifications to William Cullen's philosophical chemistry--Part I.

PubMed

Taylor, Georgette

2014-02-01

This article contributes to a growing body of research on the dissemination, dispersion or diffusion of scientific knowledge via pedagogical networks. By examining students' handwritten lecture notes, I compare the eighteenth-century chemistry lectures given by William Cullen (1710-1790) at Glasgow and Edinburgh Universities with those of his one-time student George Fordyce (1736-1802), in London, at first privately and then as part of the medical education of physicians at St. Thomas's Hospital. Part I examines the broad structure of Cullen's and Fordyce's courses, comparing both course content and pedagogical approaches to ask how far knowledge flowed directly 'downstream,' and the extent to which it was transformed, translated or transmuted in the process of transmission. Part II (forthcoming) will approach the affinity theories of Cullen and Fordyce in greater depth, revealing the dynamics of knowledge transfer. The results shed light on the transmission of knowledge and skills between master and student, and reflect on whether Fordyce can be better described as Cullen's pedagogical progeny, or less straightforwardly as a tactical translator.

Students are exposed to basic life support (BLS) and advanced cardiac life support (ACLS) training in the first semester in some medical colleges. The aim of this study was to compare students' satisfaction between lecture-based traditional method and hybrid problem-based learning (PBL) in BLS/ACLS teaching to undergraduate medical students. We conducted a questionnaire-based, cross-sectional survey among 118 1 st -year medical students from a university medical college in the city of New Delhi, India. We aimed to assess the students' satisfaction between lecture-based and hybrid-PBL method in BLS/ACLS teaching. Likert 5-point scale was used to assess students' satisfaction levels between the two teaching methods. Data were collected and scores regarding the students' satisfaction levels between these two teaching methods were analysed using a two-sided paired t -test. Most students preferred hybrid-PBL format over traditional lecture-based method in the following four aspects; learning and understanding, interest and motivation, training of personal abilities and being confident and satisfied with the teaching method ( P < 0.05). Implementation of hybrid-PBL format along with the lecture-based method in BLS/ACLS teaching provided high satisfaction among undergraduate medical students.

To explore students' perceptions (self-assessment) of their preparedness to develop collaborative practice agreements (CPAs) before and after delivery of one CPA-focused classroom lectures and 2) a CPA development student project in partnership with a local community-based pharmacy. A CPA-focused didactic lecture and subsequent project were given to second-year (P2) pharmacy students enrolled in a community pharmacy elective course at the University of Tennessee College of Pharmacy. Pre- and post-surveys were administered using an online survey platform to assess student perceptions. Responses for each survey question were summarized using frequencies, and chi-square analysis was conducted to assess the association between pre- and post-scores on each question. Students were significantly more likely to rate themselves as prepared or completely prepared to develop a CPA in a community pharmacy setting (χ 2 =61.21, p<0.01) after the course and project. Students also noted that they felt they were prepared or very prepared to work within a team to develop and implement a CPA in a community pharmacy setting (χ 2 =37.60, p<0.01). This study demonstrated that a didactic classroom lecture series followed by a student project partnered with a local community pharmacy improved perceived knowledge, preparedness, and ability to implement CPAs in a community pharmacy. Through intentional exposure of students to scope-of-practice expanding opportunities like CPAs, pharmacy educators can potentially accelerate the evolution of community pharmacy practice.

Riding a tsunami in ocean science education

An experiment began in late 1994 in which the WWW plays a critical role in the instruction of students in an oceanography course for non-majors. The format of the course consists of an equal blend of traditional lectures, tutorial-style exercises delivered from the course WWW site, classroom activities, such as poster presentations and group projects, and field excursions to local marine environments. The driving force behind the technology component of the course is to provide high-quality educational materials that can be accessed at the convenience of the student. These materials include course information and handouts, lecture notes, self-paced exercises, a virtual library of electronic resources, information on newsworthy marine events, and late-breaking oceanographic research that impacts the population of California. The course format was designed to partially meet the demands of today's students, involve students in the learning process, and prepare students for using technology in work following graduation. Students have reacted favorably to the use of the WWW and comments by peers have been equally supportive. Students are more focused in their efforts during the computer-based exercises than while listening to lecture presentations. The implementation of this form of learning, however, has not, as yet, reduced the financial cost of the course or the amount of instructor effort in providing a high quality education. Interactions between the instructor and students have increased significantly as the informality of a computer laboratory promotes individual discussions and electronic communication provides students with easy (and frequent) access to the instructor outside of class.

Lecture capturing assisted teaching and learning experience

When it comes to learning, a deep understanding of the material and a broadband of knowledge are equally important. However, provided limited amount of semester time, instructors often find themselves struggling to reach both aspects at the same time and are often forced to make a choice between the two. On one hand, we would like to spend much time to train our students, with demonstrations, step by step guidance and practice, to develop strong critical thinking skills and problem-solving skills. On the other hand, we also would like to cover a wide range of content topics to broaden our students' understanding. In this presentation, we propose a working scheme that may assist to achieve these two goals at the same time without sacrificing either one. With the help of recorded and pre-recorded lectures and other class materials, it allows instructors to spend more class time to focus on developing critical thinking skills and problem-solving skills, and to apply and connect principle knowledge with real life phenomena. It also allows our students to digest the material at a pace they are comfortable with by watching the recorded lectures over and over. Students now have something as a backup to refer to when they have random mistakes and/or missing spots on their notes, and hence take more ownership of their learning. Advanced technology have offered flexibility of how/when the content can be delivered, and have been assisting towards better teaching and learning strategies.

The 28th International Conference on Phenomena in Ionized Gases (ICPIG) was held in Prague, the capital of the Czech Republic, on 15--20 July 2007, under the sponsorship of the International Union of Pure and Applied Physics (IUPAP). The ICPIG, a traditional international conference with a remarkably long history, is held every two years and covers the fundamental physical aspects of ionized gases. It emphasizes interdisciplinary research and fosters exchange between the different communities. The 28th ICPIG was organized by the Institute of Plasma Physics, Academy Sciences of the Czech Republic with the participation of the Faculty of Electrical Engineering, Czech Technical University, and the Faculty of Mathematics and Physics of Charles University, all in Prague. The conference was attended by 619 scientists from 50 countries (537 participants from outside the host country) and, compared with preceding meetings, ICPIG in Prague came with several changes. The pocket program and CD proceedings have been replaced by the book of abstracts, pocket program and CD containing full-length contributions. The International Scientific Committee also decided to update substantially the list of ICPIG topics. These topics have been grouped into four major sections: A. Fundamentals; B. Modelling, Simulation and Diagnostics; C. Plasma Sources and Discharge Regimes; D. Applications, with each major section structured into several sub-topics. Last but not least, on the occasion of ICPIG 2007, the IUPAP Early Career Award in Plasma Physics was bestowed for the first time. Complete 28th ICPIG conference records include the von Engel Prize Lecture, 10 general and 26 topical invited lectures, 18 workshop lectures and the contributed papers (http://icpig2007.ipp.cas.cz/). All 718 submitted full-length contributed papers were reviewed and 608 contributions were accepted for poster presentation. It is worth noting that 98 of the total of 608 poster contributions belong to the topic 'Non-equilibrium Plasmas and Micro-plasmas at High Pressures', reflecting new trends in the field. Important parts of the conference were two workshops focused on specific themes. The workshop 'Pulsed electrical discharges in water: fundamentals and applications', organized by Professor Pavel Sunka, reviewed the scientific challenges related to fundamentals of pulsed discharges initiated in slightly conductive liquid water solutions. The workshop 'Physics and applications of pulsed high-current capillary discharges', organized by Dr Karel Kolácek, addressed scientific challenges and technological applications of high-current capillary discharges pinching into a nearly uni-dimensional dense plasma column composed of a quasi-neutral mixture of very hot electrons and multiply charged ions. All ICPIG speakers were invited to prepare peer-reviewed articles based on their conference lectures for the journal Plasma Sources Sciences and Technology (PSST) in the form of either reviews or original works. A selection of invited papers is published in this special issue. We would like to thank all authors for their effort in preparing interesting articles for the readers of PSST. We would like to thank once more all members of the International Scientific Committee chaired by Professor Jerzy Mizeraczyk as well as the members of the Local Organizing Committee and the National Advisory Board for their considerable contributions to the success of the conference. We are particularly grateful to the Editorial Board of Plasma Sources Science and Technology for the opportunity to bring the 28th ICPIG to a wider audience.

Training Graduate Teaching Assistants in the Geosciences: Our Practices vs. Perceived Needs

NASA Astrophysics Data System (ADS)

Teasdale, R.; Ryker, K.; Bitting, K. S.

2016-12-01

Graduate Teaching Assistants (GTAs) in the geosciences are responsible for teaching a large proportion of undergraduate students in many universities. Often, GTAs are primary instructors in small laboratory sections of large enrollment courses, putting them in the position of having a more personalized relationship with students, in what is often the most interactive portion of an introductory course. Anecdotally, geoscientists recognize that GTAs also have a broad range of responsibilities, but there is wide variation in the content and timing of the training they receive. Until now, no comprehensive survey has been conducted to capture and analyze this distribution in a systematic way. Data from a nationwide survey of 120 geoscientists is used here to characterize the ways GTAs are trained as well as respondents' priorities for GTA training. Respondents include faculty from PhD- and MS- granting institutions (81.4%) and MS-only granting institutions (18.5%). According to the survey, most GTAs teach laboratory sections (95.6%), and many teach lecture sections (38.9%). In many cases, GTAs support instructors during or outside of the "lecture" section (e.g. grading, 77.1%). Of GTAs who teach lecture or lab sections, most receive required training from their department or the university, commonly on a single day just before the start of the semester. GTA training typically includes logistical information (where to find materials, professionalism), but less than 40% of GTAs are required to participate in pedagogical training. In contrast, pedagogy was most often rated very important or important (74.2%) by survey respondents. The disconnect between the geoscience community's current practices in GTA training and our current values suggests that GTA training programs are needed, and that the community can benefit from reports on the success of existing programs and the dissemination of adaptable models for GTA pedagogical training.

George Mason University has first semester (PHYS-160) and second semester (PHYS-260) physics course which consist of two sections. One is a traditional lecture style format (TRAD) and the other is a newer format which is a take on the ``flipped'' classroom. This newer style is referred to as Active Learning with Technologies (ALT). This course style has been in place for several years and has been studied before within George Mason University for final grade differences. These studies suggested that the ALT sections performed better, but grade weighting consistency, test time, and test content were not strictly controlled. The purpose of this study is to cross-examine the performance of students in these different class formats during Fall 2016 (PHYS-260) and Spring 2015 (PHYS-160) on very nearly identical exams over identical test times while controlling for almost every variable.

Hidden simplicity of gauge theory amplitudes

Drummond, J. M.

2010-11-01

These notes were given as lectures at the CERN Winter School on Supergravity, Strings and Gauge Theory 2010. We describe the structure of scattering amplitudes in gauge theories, focussing on the maximally supersymmetric theory to highlight the hidden symmetries which appear. Using the Britto, Cachzo, Feng and Witten (BCFW) recursion relations we solve the tree-level S-matrix in \\ {N}=4 super Yang-Mills theory and describe how it produces a sum of invariants of a large symmetry algebra. We review amplitudes in the planar theory beyond tree level, describing the connection between amplitudes and Wilson loops, and discuss the implications of the hidden symmetries.

We give an exact formulation for the transport coefficients of incommensurate two-dimensional atomic multilayer systems in the tight-binding approximation. This formulation is based upon the C* algebra framework introduced by Bellissard and collaborators [Coherent and Dissipative Transport in Aperiodic Solids, Lecture Notes in Physics (Springer, 2003), Vol. 597, pp. 413-486 and J. Math. Phys. 35(10), 5373-5451 (1994)] to study aperiodic solids (disordered crystals, quasicrystals, and amorphous materials), notably in the presence of magnetic fields (quantum Hall effect). We also present numerical approximations and test our methods on a one-dimensional incommensurate bilayer system.

Kuiper Prize Lecture - Present and past climates of the terrestrial planets

1991-01-01

An evaluation is undertaken of the current understanding of factors shaping the current climates of Venus, Mars, and the earth, in conjunction with the ways in which these planetary climates may have been different in the past. Attention is given to modeling approaches of various levels of sophistication which both characterize current climates and elucidate prior climatic epochs; these are assessed in light of observational data in order to judge degrees of success thus far and formulate major remaining questions for future investigations. Venus is noted to offer excellent opportunities for modeling the greenhouse effect.
