    Gelula, M H

    1997-02-01

    Lectures are the most popular form of teaching in medical education. As much as preparation and organization are key to the lecture's success, the actual presentation also depends upon the presenter's ability to reach the audience. Teaching is a lively activity. It calls for more than just offering ideas and data to an audience. It calls for direct contact with the audience, effective use of language, capability to use limited time effectively, and the ability to be entertaining. This article offers a structure to effective lecturing by highlighting the importance of voice clarity and speaking speed, approaches to using audiovisual aids, effectively using the audience to the lecture, and ways to be entertaining.

  9. The clinical role of nurse lecturers: Past, present, and future.

    PubMed

    Barrett, David

    2007-07-01

    The clinical role of nurse lecturers has been the subject of much debate since the transfer of nurse education into Higher Education Institutions within the United Kingdom. This article provides a critical evaluation of the clinical role of nurse lecturers in terms of policy drivers and strategies for implementing national guidelines. Policies from the initiation of Project 2000, through to recent consultation documents on the support of students in practice, are evaluated. Formal aspects of the nurse lecturer remit, such as link tutor and personal supervisor roles, are discussed in terms of their impact on clinical practice. There is also a brief review of the development of the lecturer practitioner role as a bridge between education and practice. The fundamental arguments in support of nurse lecturers maintaining a clinical role in practice are analysed. This analysis includes consideration of the concept of 'clinical credibility' in terms of the impact on teaching and the closure of the theory-practice gap. The article concludes with suggestions for strategies to resolve the ongoing debate surrounding the clinical role of nurse lecturers. These recommendations include a review of staff:student ratios in nurse education, re-evaluation of the need for a clinical role, and the use of innovative recruitment and development strategies by higher education institutions.

  10. Using paper presentation breaks during didactic lectures improves learning of physiology in undergraduate students.

    Ghorbani, Ahmad; Ghazvini, Kiarash

    2016-03-01

    Many studies have emphasized the incorporation of active learning into classrooms to reinforce didactic lectures for physiology courses. This work aimed to determine if presenting classic papers during didactic lectures improves the learning of physiology among undergraduate students. Twenty-two students of health information technology were randomly divided into the following two groups: 1) didactic lecture only (control group) and 2) didactic lecture plus paper presentation breaks (DLPP group). In the control group, main topics of gastrointestinal and endocrine physiology were taught using only the didactic lecture technique. In the DLPP group, some topics were presented by the didactic lecture method (similar to the control group) and some topics were taught by the DLPP technique (first, concepts were covered briefly in a didactic format and then reinforced with presentation of a related classic paper). The combination of didactic lecture and paper breaks significantly improved learning so that students in the DLPP group showed higher scores on related topics compared with those in the control group (P < 0.001). Comparison of the scores of topics taught by only the didactic lecture and those using both the didactic lecture and paper breaks showed significant improvement only in the DLPP group (P < 0.001). Data obtained from the final exam showed that in the DLPP group, the mean score of the topics taught by the combination of didactic lecture and paper breaks was significantly higher than those taught by only didactic lecture (P < 0.05). In conclusion, the combination of paper presentation breaks and didactic lectures improves the learning of physiology.

  16. Nobel Prize Recipient Eric Betzig Presents Lecture on Efforts to Improve High-Resolution Microscopy | Poster

    Cancer.gov

    Eric Betzig, Ph.D., a 2014 recipient of the Nobel Prize in Chemistry and a scientist at Janelia Research Campus (JRC), Howard Hughes Medical Institute, in Ashburn, Va., visited NCI at Frederick on Sept. 10 to present a Distinguished Scientist lecture and discuss the latest high-resolution microscopy techniques. Betzig co-invented photoactivation localization microscopy (PALM) in collaboration with scientists at NIH. PALM achieves 10-fold improvement in spatial resolution of cells, going from the resolution limit of approximately 250 nm in standard optical microscopy down to approximately 20 nm, thus producing a so-called “super-resolution” image. Spatial resolution refers to the clarity of an image or, in other words, the smallest details that can be observed from an image.

    In February 1924, at the invitation of C. A. Chant, Russell presented a set of 14 public lectures on the state of astronomy and astrophysics. Designed to be inspirational, they also reveal Russell's contemporary views on the state of astrophysics as well as his sense of proper practice in astronomy. During his visit, Russell was interviewed by local reporters who asked his opinion about building a large observatory, one of Chant's major projects. What Russell had to say about such ventures did not please Chant one bit.

  3. New Learning Method of a Lecture of ‘Machine Fabrication’ by Self-study with Investigation and Presentation Incorporated

    NASA Astrophysics Data System (ADS)

    Kasuga, Yukio

    A new teaching method was developed in learning ‘machine fabrication’ for the undergraduate students. This consists of a few times of lectures, grouping, decision of industrial products which each group wants to investigate, investigation work by library books and internet, arrangement of data containing characteristics of the products, employed materials and processing methods, presentation, discussions and revision followed by another presentation. This new method is derived from one of the Finland‧s way of primary school education. Their way of education is believed to have boosted up to the top ranking in PISA tests by OECD. After starting the new way of learning, students have fresh impressions on this lesson, especially for self-study, the way of investigation, collaborate work and presentation. Also, after four years of implementation, some improvements have been made including less use of internet, and determination of products and fabricating methods in advance which should be investigated. By this, students‧ lecture assessment shows further encouraging results.

    NASA Astrophysics Data System (ADS)

    Osborne, Jonathan

    2010-02-01

    João Magueijo's article "Cargo-cult training" about the failings of compulsory educational training for lecturers (December 2009 pp16-17) is an illustration of why some university lecturers do need to be educated about education. His argument that we should use lectures because students like them ignores the large body of educational research stating that this is the least effective form of education. It might, as the well-known aphorism states, be a successful means of transferring the notes of the lecturer to the notes of the students without going through the minds of either, but the evidence shows that only 10% of students learn material in this way. Rather, all the educational literature points to the fact that interactive, discursive methods are much more likely to produce learning with understanding.

  13. The James Blundell Award Lecture 2006: transfusion and the treatment of haemorrhage: past, present and future.

    PubMed

    Dzik, W H

    2007-10-01

    In the early years of the 19th century, James Blundell reported in the Lancet the first clinical application of blood transfusion for the treatment of haemorrhage. Although these initial experiments may appear to us to have burst upon the medical world, Blundell had in fact done a decade of pre clinical research using animal models to establish principles to be brought to the clinic. His pivotal pre clinical experiments and the insights he gained are described in detail. Today, blood transfusion remains the cornerstone of treatment for serious bleeding - not only to restore oxygen carrying capacity but also to improve haemostasis, arrest and prevent bleeding. However, the indications for the use of blood components to treat bleeding remain ill-defined. In particular, despite the enormous volumes of fresh frozen plasma (FFP) transfused worldwide, the evidence that commonly used coagulation tests are reliable guides to transfusion with FFP is scant. Recent laboratory and clinical studies provide insight into the weaknesses of current coagulation tests as a guide to blood management. In the future, the application of genomics to haemostasis will uncover genetic polymorphisms leading to improved diagnostics and more tailored medical therapeutics. Examples of the emerging use of clinical genomics are presented. Ultimately, the application of widescale genomics testing will refresh our understanding of human physiology and will reassert the importance of the individual in patient care.

  14. Data Collection, Access and Presentation Technologies in the National Ecological Observatory (NEON) Design (Invited)

    NASA Astrophysics Data System (ADS)

    Aulenbach, S. M.; Berukoff, S. J.

    2010-12-01

    The National Ecological Observatory Network (NEON) will collect data across the United States on the impacts of climate change, land use change and invasive species on ecosystem functions and biodiversity. In-situ sampling and distributed sensor networks, linked by an advanced cyberinfrastructure, will collect site-based data on a variety of organisms, soils, aquatic systems, atmosphere and climate. Targeted airborne remote sensing observations made by NEON as well as geographical data sets and satellite resources produced by Federal agencies will provide data at regional and national scales. The resulting data streams, collected over a 30-year period, will be synthesized into fully traceable information products that are freely and openly accessible to all users. We provide an overview of several collection, access and presentation technologies evaluated for use by observatory systems throughout the data product life cycle. Specifically, we discuss smart phone applications for citizen scientists as well as the use of handheld devices for sample collection and reporting from the field. Protocols for storing, queuing, and retrieving data from observatory sites located throughout the nation are highlighted as are the application of standards throughout the pipelined production of data products. We discuss the automated incorporation of provenance information and digital object identifiers for published data products. The use of widgets and personalized user portals for the discovery and dissemination of NEON data products are also presented.

  15. The Archeomagnetic field in South America: Present status and perspectives (Invited)

    Hartmann, G. A.; Trindade, R. I.; Gallet, Y.; Poletti, W.; Begnini, G. S.; Genevey, A.; Legoff, M.

    2013-12-01

    Geomagnetic field variations over decadal to millennial timescales can be determined from direct (i.e. observatory) and indirect (e.g. from archeological artifacts and volcanics) sources. Before the observatory era, the recovery of these variations is however still strongly penalized by the very uneven both geographical and temporal distributions of the available archeo/paleomagnetic dataset. In particular, the southern hemisphere contributes with only ~3% of the global archeomagnetic database. Moreover, most of these data present restrictions due to their poor experimental reliability and to the lack of good age control. Therefore, new intensity and directional data from the southern hemisphere are strongly requested for the next generation of archeomagnetic field models. In this presentation, we will report on intensity and inclination results obtained from different regions in Brazil. A collection of twenty-three site-mean archeointensity data were obtained by our team from architectural brick fragments dated to the past 500 years from Northeast and Southeast Brazil. This dataset was complemented by a series of new results from South Brazil. In addition, we also obtained inclination data, after reconstructing the firing position of the ancient bricks from modern analogs of historical brickyards. Thirteen site-mean inclination results dated to between 1790 AD and 1950 AD and five inclination results spanning the 1590-1920 AD time interval were so determined from Southeast and Northeast Brazil, respectively. Altogether, our data, which are geographically distributed over more than 20 degrees in latitude, allow us to discuss the large-scale influence in Brazil and South America of non-dipolar features of the geomagnetic field during the past few centuries.

  16. Polarization in heavy-ion reactions. [Lectures

    SciTech Connect

    Fick, D.

    1983-08-01

    Determination of the polarization and spin alignment of reaction products emitted from heavy ion reactions should provide a sensitive test of reaction mechanisms. Techniques for producing both polarized beams and polarized targets are advancing rapidly. At the Oak Ridge National Laboraotry interest in this field has lead to the design and construction of a laser optically pumped polarized target by illuminating a supersonic gas jet. This target, which is mounted in the scattering chamber of a magnetic spectrometer, will be used to observe effects when deformed polarized targets are bombarded by heavy ions. Mutual research interests led to the invitation of Professor Fick, a pioneer in heavy ion polarization research who recently reviewed the status of this field, to Oak Ridge. While at ORNL he presented a series of lectures on this subject. Notes from these lectures are presented. (WHK)

    Wofford, M M; Spickard, A W; Wofford, J L

    2001-07-01

    Advancing computer technology, cost-containment pressures, and desire to make innovative improvements in medical education argue for moving learning resources to the computer. A reasonable target for such a strategy is the traditional clinical lecture. The purpose of the lecture, the advantages and disadvantages of "live" versus computer-based lectures, and the technical options in computerizing the lecture deserve attention in developing a cost-effective, complementary learning strategy that preserves the teacher-learner relationship. Based on a literature review of the traditional clinical lecture, we build on the strengths of the lecture format and discuss strategies for converting the lecture to a computer-based learning presentation.

  1. Ida Mann Lecture 2007: Planet eye.

    PubMed

    McMenamin, Paul G

    2008-10-01

    The concept for this lecture arose as a consequence of the invitation from the College to give the 'Ida Mann Lecture' arriving recently after I had enjoyed the beautiful David Attenborough series 'Planet Earth' on television. It struck me as not too fanciful an idea at the time to make an analogy between 'Planet Earth' and the eye and thus the idea of giving an Attenborough-like tour of the ocular microenvironments and making the analogy between various immune cells in the eye and wildlife on planet Earth was born. I could only hope that in some small measure my presentation would inspire and educate an audience of ophthalmologists on the amazing world of ocular immune cells in the way that David Attenborough enraptures millions of television viewers with his beautiful series.

  2. Memory for Lectures: How Lecture Format Impacts the Learning Experience

    PubMed Central

    Varao-Sousa, Trish L.; Kingstone, Alan

    2015-01-01

    The present study investigated what impact the presentation style of a classroom lecture has on memory, mind wandering, and the subjective factors of interest and motivation. We examined if having a professor lecturing live versus on video alters the learning experience of the students in the classroom. During the lectures, students were asked to report mind wandering and later complete a memory test. The lecture format was manipulated such that all the students received two lectures, one live and one a pre-recorded video. Results indicate that lecture format affected memory performance but not mind wandering, with enhanced memory in the live lectures. Additionally, students reported greater interest and motivation in the live lectures. Given that a single change to the classroom environment, professor presence, impacted memory performance, as well as motivation and interest, the present results have several key implications for technology-based integrations into higher education classrooms.

    Asai, Kikuo; Kondo, Kimio; Kobayashi, Hideaki; Saito, Fumihiko

    We developed a prototype system to support telecommunication by using keywords selected by the speaker in a videoconference. In the traditional presentation style, a speaker talks and uses audiovisual materials, and the audience at remote sites looks at these materials. Unfortunately, the audience often loses concentration and attention during the talk. To overcome this problem, we investigate a keyword presentation style, in which the speaker holds keyword cards that enable the audience to see additional information. Although keyword captions were originally intended for use in video materials for learning foreign languages, they can also be used to improve the quality of distance lectures in videoconferences. Our prototype system recognizes printed keywords in a video image at a server, and transfers the data to clients as multimedia functions such as language translation, three-dimensional (3D) model visualization, and audio reproduction. The additional information is collocated to the keyword cards in the display window, thus forming a spatial relationship between them. We conducted an experiment to investigate the properties of the keyword presentation style for an audience. The results suggest the potential of the keyword presentation style for improving the audience's concentration and attention in distance lectures by providing an environment that facilitates eye contact during videoconferencing.

    The present evaluation of the use of new observational methods for exploring solar system evolutionary processes gives attention to illustrative cases from the constraining of near-earth asteroid sources and the discovery of main-belt asteroid fragments which indicate Vesta to be a source of basaltic achondrite meteorites. The coupling of observational constraints with numerical models clarifies cratering and collisional evolution for both main-belt and Trojan asteroids.

  7. The Optic UK Lecture: bench-to-bedside adventures of a diabetes researcher: results past, results present.

    PubMed

    Frank, R N

    2011-03-01

    This presentation covers two topics. First is a basic laboratory study, designed to explore the mechanism for the phenomenon of 'early worsening,' in which individuals with type 1 diabetes and early to moderate retinopathy are rapidly placed on 'tight' blood glucose control, after which about 10% of these individuals develop a worsening of retinopathy with the appearance of multiple 'cotton wool' spots. Our studies on cultured retinal cells used vascular endothelial growth factor (VEGF) production as an index of cellular ischaemia. VEGF production increases substantially when cells are cultured in low oxygen, but VEGF production in these hypoxic cultures decreases when the medium contains a fivefold excess glucose concentration. Cultures with no medium glucose also show increased VEGF production. In the clinical situation, we infer from these results that retinas with early retinopathy have a reduced blood supply and are therefore relatively ischaemic, thus increasing their VEGF production. Adding glucose provides an alternative energy supply, thus reducing the demand for VEGF and hence, reducing the likelihood of 'early worsening.' However, reducing the glucose supply to these already compromised retinas further increases their ischaemia and, therefore, the stimulus to produce more VEGF. The second part of this presentation is a clinical exploration of possible reasons for the frequent, wide discrepancy between measured central macular thickness by optical coherence tomography (OCT) and visual acuity in eyes with diabetic macular oedema. I explore the influence of different diseases in which macular oedema appears, the presence or absence, and size, of cystoid cavities; duration of the oedema; age of the subject, different anatomic derangements including epiretinal membranes and disruptions of the photoreceptor layer, and various biochemical and physiological mechanisms.

    2014-02-01

    With the proliferation of new affordable recording technologies, many universities have begun offering students recordings of live lectures as a part of the course resources. We conducted a survey to investigate why some students choose to attend lectures in person rather than simply watching the recordings online, and how students view the two types of lectures. Students attending live lectures in five large undergraduate mathematics lecture streams were invited to respond to the survey. A significant number of respondents viewed recorded lecture as superfluous to their needs which were met upon attending live lecture. Surprisingly, however, an equally large number of students described compelling reasons for watching both live and recorded lectures. A number of factors were identified as determining students' perceptions of live and recorded lectures as competing or complementary: personal learning styles, study habits, esteem for the lecturer, and the possibility of interaction in the lecture.

    2010-12-01

    One of the greatest legacies of the International Polar Year (IPY) is the creation of APECS, the Association of Polar Early Career Scientists. As a grassroots effort, APECS was proposed, formed, and developed by and for early career polar researchers. While the young investigators who founded APECS had talent, ambition, and the desire to make things happen, partnerships with key organizations and experienced leaders in polar science were essential to provide the funding, leadership, and mentorship that has taken the organization well beyond the IPY and to over 2000 members. In four years, APECS has strived to foster the skills of and develop a group of early career interdisciplinary polar scientists through networking and mentoring among themselves and with senior scientists. Through diverse activities including, panel discussions, career development workshops, online seminars, a comprehensive job listing, formal mentoring, meeting travel support, and the APECS Virtual Poster Session, APECS goal is to support the early career researcher being trained to do the science, to become a well-rounded scientist prepared for 21st century careers in science. As part of that training, APECS members are encouraged to participate in activities and training related to science communication, education, and outreach; working with the media; participating in the science / public policy interface; and working with arctic communities and indigenous peoples. During the IPY, APECS members were guest speakers and presenters on International Polar Day activities; they contributed to resources for education and outreach such as the book: Polar Science and Global Climate: An International Resource for Education and Outreach; and they made connections with educators, community groups, the media through in-person presentations, blogs from the field, videos, and much more. Workshops, panels, and online discussions focusing on these activities helped develop the capacity to conduct such

  11. Lectures in accelerator theory

    SciTech Connect

    Month, M

    1980-01-01

    Lecture I deals with the behavior of particles in the nonlinear field arising from the electromagnetic interaction of colliding beams. The case treated, that of counter-rotating proton beams crossing each other at a non-zero angle, has the simple feature that the force between the beam is one dimensional. In lecture II, an analysis of the development of traveling waves on particle beams is presented. The situation studied is that of a uniform beam current in a circular accelerator and the excitation for the coherent motion is induced by the resistivity of the vacuum chamber wall. Finally, in lecture III, a description of the current accumulation process used at the proton storage rings at CERN (The ISR) is given. Particle pulses of rather low average current are injected and stored along the length and width of the vacuum chamber. The efficiency is very high and large currents (over 40 amperes) have been achieved.

    In times of manifold digital learning resources open to public access lectures in surgery still play a major role in medical training. It is a platform for discussion with the medical teacher and provides the opportunity to create a vivid learning experience by showing live operations via video streaming and inviting patients to the lectures. When then change in paradigm is achieved from pure knowledge transfer to cross-linkage of knowledge, the surgical lecture will be a major future keystone in medical education, where the lecturer can reach the students with his own passion for the field of expertise and get them interested in surgery.

    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.

    2015-04-01

    Lecturing is an essential teaching skill for scientists and health care professionals in pulmonary, critical care, and sleep medicine. However, few medical or scientific educators have received training in contemporary techniques or technology for large audience presentation. Interactive lecturing outperforms traditional, passive-style lecturing in educational outcomes, and is being increasingly incorporated into large group presentations. Evidence-based techniques range from the very simple, such as inserting pauses for audience discussion, to more technologically advanced approaches such as electronic audience response systems. Alternative software platforms such as Prezi can overcome some of the visual limits that the ubiquitous PowerPoint imposes on complex scientific narratives, and newer technology formats can help foster the interactive learning environment. Regardless of the technology, adherence to good principles of instructional design, multimedia learning, visualization of quantitative data, and informational public speaking can improve any lecture. The storyline must be clear, logical, and simplified compared with how it might be prepared for scientific publication. Succinct outline and summary slides can provide a roadmap for the audience. Changes of pace, and summaries or other cognitive breaks inserted every 15-20 minutes can renew attention. Graphics that emphasize clear, digestible data graphs or images over tables, and simple, focused tables over text slides, are more readily absorbed. Text slides should minimize words, using simple fonts in colors that contrast to a plain background. Adherence to these well-established principles and addition of some new approaches and technologies will yield an engaging lecture worth attending.

    Langston University, a Historically Black University located at Langston, Oklahoma, has a computing and information science program within the Langston University Division of Business. Since 1984, Langston University has participated in the Historically Black College and University program of the U.S. Department of Interior, which provided education, training, and funding through a combined earth-science and computer-technology cooperative program with the U.S. Geological Survey (USGS). USGS personnel have presented guest lectures at Langston University since 1984. Students have been enthusiastic about the lectures, and as a result of this program, 13 Langston University students have been hired by the USGS on a part-time basis while they continued their education at the University. The USGS expanded the offering of guest lectures in 1992 by increasing the number of visits to Langston University, and by inviting participation of speakers from throughout the country. The objectives of the guest-lecture series are to assist Langston University in offering state-of-the-art education in the computer sciences, to provide students with an opportunity to learn from and interact with skilled computer-science professionals, and to develop a pool of potential future employees for part-time and full-time employment. This report includes abstracts for guest-lecture presentations during 1992-93 school year.

    Background Lectures are good for presenting information and providing explanations, but because they lack active participation they have been neglected. Methods Students' experiences were evaluated after exposing them to the use of voting during lectures in their paediatrics course. Questions were delivered to the students taking paediatrics course. Thirty-six students out of the total of 40 (90%) attended the opening lecture, at which the first survey concerning previous experiences of lectures was performed. Thirty-nine students (98%) answered the second series of questions at the end of the paediatrics course. Results Most of the students felt that voting improved their activity during lectures, enhanced their learning, and that it was easier to make questions during lectures than earlier. Conclusions The students gained new, exciting insights much more often during the paediatrics course than before. We as teachers found that voting during lectures could easily overcome some of the obstacles of good lecturing. PMID:14678571

    Historically, invited lecturers have often challenged us to define excel lence in physical therapy practice, or in our academic programs. While some have addressed different char acteristics of excellence, our profession has not really come together to address 2 very important questions: what does "quality" mean in physical therapist education? And how do we measure it? Using 3 elements of Friendship, Leadership, and Mentoring, and Defining Excellence and juxtaposing these with Linda Crane and her life, a vision of excellence in physical therapy educational programs was explored in this invited lecture.

    This lecture will cover solar thermal radiation, particularly as it relates to the high energy solar processes that are the subject of this summer school. After a general review of thermal radiation from the Sun and a discussion of basic definitions, the various emission and absorption mechanisms will be described including black-body emission, bremsstrahlung, free-bound, and atomic line emissions of all kinds. The bulk of the time will be spent discussing the observational characteristics of thermal flare plasma and what can be learned about the flare energy release process from observations of the thermal radiation at all wavelengths. Information that has been learned about the morphology, temperature distribution, and composition of the flare plasma will be presented. The energetics of the thermal flare plasma will be discussed in relation to the nonthermal energy of the particles accelerated during the flare. This includes the total energy, the radiated and conductive cooling processes, and the total irradiated energy.

    Bull, Peter

    2006-09-01

    According to Atkinson (e.g. 1983, 1984a, 1984b), a limited range of rhetorical devices are consistently used by political speakers to invite audience applause. A detailed review is presented of the research literature relevant to Atkinson's analysis, including a series of evaluative studies conducted by the author. From this review, it is argued that Atkinson overestimated the role of rhetorical devices in inviting applause and underestimated the significance of other features, such as asynchronous applause, speech delivery, speech content and uninvited applause. To integrate these features, a re-conceptualisation is presented of how audience applause occurs in political speeches, based on a fundamental distinction between invited and uninvited applause.

    2014-01-01

    Background The lecture remains the most common approach for didactic offerings in residency programs despite conflicting evidence about the effectiveness of this format. Objective The purpose of this study was to explore the perspectives of internal medicine residents toward conferences held in the lecture format. Methods The investigators invited internal medicine residents (N  =  144) to participate in focus groups discussing their perspectives about noon conference lectures. The investigators used a semistructured guide to ask about motivations for attendance and effectiveness of noon conferences, transcribed the recordings, coded the discussions, and analyzed the results. Results Seven focus groups with a total of 41 residents were held. This identified 4 major domains: (1) motivations for attendance; (2) appropriate content; (3) effective teaching methods; and (4) perspectives on active participation. Residents' motivations were categorized into external factors, including desire for a break and balance to their workload, and intrinsic attributes, including the learning opportunity, topic, and speaker. Appropriate content was described as clinically relevant, practical, and presenting a balance of evidence. Identified effective teaching methods included shorter teaching sessions focused on high-yield learning points structured around cases and questions. While active participation increases residents' perceived level of stress, the benefits of this format include increased attention and learning. Conclusions This study furthers our knowledge of the learning preferences of internal medicine residents within the changing environment of residency education and can be used in conjunction with principles of adult learning to reform how we deliver core medical knowledge.

    2016-01-01

    This mini review presents a personal view about the past, the present and the future of the relationship between growth retardation and the IGF system. Looking back, it is pertinent to include a brief look at the evolution of the somatomedin hypothesis, the use of IGF-I determinations in the clinic, and a review of the literature beginning in the late 1980s with the description of mutations in the Growth Hormone Receptor (GHR) gene. The present possibly started in the mid-1990s with the description of mutations in the IGF-I gene, followed in 2003 by reports of mutations in the genes coding for the IGF-I receptor and in the signal transducer and activator of transcription 5b (STAT5b). Finally, in 2004, mutations in the IGFALS gene were described. A diffuse limit between the present and the future might have been reached (the author's arbitrary decision) with the clinical applications of whole exome sequencing, which rapidly showed mutations in genes coding for STAT3, PAPP-A2 (pregnancy-associated plasma protein A2), and IGF-II.

  4. Shattuck Lecture--strengths and weaknesses of the committee approach. An analysis of past and present recommended dietary allowances for protein in health and disease.

    PubMed

    Scrimshaw, N S

    1976-01-15

    A review of the history of international efforts to establish protein requirements and safe allowances for healthy adults reveals the difficulties of the expert-committee approach to problems of this nature. Although it is preferable to less democratic approaches, the committees involved often acted without sufficient knowledge of the relevant literature and seldom had time to study and evaluate unpublished data presented at the meetings. Moreover, the available data are still inadequate for the purpose, even though each meeting report has stimulated additional relevant research. Research since the 1971 meeting of the FAO/WHO Expert Committee on Energy and Protein Requirements has already cast doubt on its recommendations. Recent evidence suggests that the "safe allowance of protein" that it proposed is inadequate for long-term maintenance of healthy in young adults even when energy intakes are wholly adequate or even excessive.

    the state of atmospheric circulation in the Southern Hemisphere that will result as a consequence of greenhouse gas rise and "healing" of the Antarctic ozone hole (Mayewski et al., 2015). Climate change perspective gained from instrumentally calibrated ice core and other past climate proxies is essential to the construction of plausible scenarios for future climate and actionable planning. More ACC events are in our future and the early manifestation of these events is apparent in the emerging change in the severity and frequency of extreme events. Searching for a precursor for ACC events is a major challenge for the scientific community and humanity. For the climate community to undertake this challenge it is necessary to investigate both past and present sub-seasonal and longer extreme events associated with past D-O and ACC events and their impact on societies. Examples of sub-seasonal scale investigation of these events will be included in the presentation.

    Lower visibility of female scientists, compared to male scientists, is a potential reason for the under-representation of women among senior academic ranks. Visibility in the scientific community stems partly from presenting research as an invited speaker at organized meetings. We analysed the sex ratio of presenters at the European Society for Evolutionary Biology (ESEB) Congress 2011, where all abstract submissions were accepted for presentation. Women were under-represented among invited speakers at symposia (15% women) compared to all presenters (46%), regular oral presenters (41%) and plenary speakers (25%). At the ESEB congresses in 2001-2011, 9-23% of invited speakers were women. This under-representation of women is partly attributable to a larger proportion of women, than men, declining invitations: in 2011, 50% of women declined an invitation to speak compared to 26% of men. We expect invited speakers to be scientists from top ranked institutions or authors of recent papers in high-impact journals. Considering all invited speakers (including declined invitations), 23% were women. This was lower than the baseline sex ratios of early-mid career stage scientists, but was similar to senior scientists and authors that have published in high-impact journals. High-quality science by women therefore has low exposure at international meetings, which will constrain Evolutionary Biology from reaching its full potential. We wish to highlight the wider implications of turning down invitations to speak, and encourage conference organizers to implement steps to increase acceptance rates of invited talks.

    The origin of the asymmetry between matter and anti-matter of the Universe has been one of the great challenges in particle physics and cosmology. Leptogenesis as a mechanism for generating the cosmological baryon asymmetry of the Universe has gained significant interests ever since the advent of the evidence of non-zero neutrino masses. In these lectures presented at TASI 2006, I review various realizations of leptogenesis and allude to recent developments in this subject.

    Abstracts of 25 papers relating to condensation processes in the early solar system are presented. Special emphasis is given to the transition of an initial vapor phase in the space medium, the characterization of condensation environments, and condensation processes in the space medium. The question of whether some fraction of the solar system solids (particularly exemplified by meteoritic solids) may be interstellar grains that gathered in the region of the proto-sun, rather than being products of local condensation is addressed.

  11. 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.

    These lecture notes survey some joint work with Samson Abramsky as it was presented by me at several conferences in the summer of 2005. It concerns 'doing quantum mechanics using only pictures of lines, squares, triangles and diamonds'. This picture calculus can be seen as a very substantial extension of Dirac's notation, and has a purely algebraic counterpart in terms of so-called Strongly Compact Closed Categories (introduced by Abramsky and I which subsumes my Logic of Entanglement. For a survey on the 'what', the 'why' and the 'hows' I refer to a previous set of lecture notes. In a last section we provide some pointers to the body of technical literature on the subject.

    Readers may recall the interview with Professor Peter Kalmus which appeared in the July issue of Physics Education and which indicated his latest role of lecturer for the 1998-9 Institute of Physics Schools and Colleges Lecture series. This year's lecture is entitled `Particles and the universe' and the tour was due to begin in St Andrews, Scotland, late in September. Professor Kalmus will be looking at various aspects of particle physics, quantum physics and relativity, and discussing how they reveal the secrets of the beginning of our universe. His own experience of working at CERN, the European centre for particle physics in Switzerland, as well as at other international research facilities will provide a unique insight into activity in one of the most exciting areas of physics. The talks are aimed at the 16-19 age group but members of the public are also welcome to attend. They will act as an opportunity to gain a sneak preview of the dynamic new topics that will soon feature in the A-level syllabus arising from the Institute's 16-19 project.

    Jonathan Osborne's letter (February p20) in response to João Magueijo's article on university-lecturer training (December 2009 pp16-17) surely cannot go unanswered. Contrary to what Osborne claims, Magueijo did not say that we should use lectures because students like them - in fact, he advocated the use of exactly the "interactive, discursive methods" that Osborne favours as alternatives to traditional lecture courses. The real point of Magueijo's article was that lecturer training as currently practised in the UK is a waste of time - not that lecturers need no training at all.

  17. Lecture Notes on Multigrid Methods

    SciTech Connect

    Vassilevski, P S

    2010-06-28

    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-vector 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.

  9. Lecture notes for criticality safety

    SciTech Connect

    Fullwood, R.

    1992-03-01

    These lecture notes for criticality safety are prepared for the training of Department of Energy supervisory, project management, and administrative staff. Technical training and basic mathematics are assumed. The notes are designed for a two-day course, taught by two lecturers. Video tapes may be used at the options of the instructors. The notes provide all the materials that are necessary but outside reading will assist in the fullest understanding. The course begins with a nuclear physics overview. The reader is led from the macroscopic world into the microscopic world of atoms and the elementary particles that constitute atoms. The particles, their masses and sizes and properties associated with radioactive decay and fission are introduced along with Einstein`s mass-energy equivalence. Radioactive decay, nuclear reactions, radiation penetration, shielding and health-effects are discussed to understand protection in case of a criticality accident. Fission, the fission products, particles and energy released are presented to appreciate the dangers of criticality. Nuclear cross sections are introduced to understand the effectiveness of slow neutrons to produce fission. Chain reactors are presented as an economy; effective use of the neutrons from fission leads to more fission resulting in a power reactor or a criticality excursion. The six-factor formula is presented for managing the neutron budget. This leads to concepts of material and geometric buckling which are used in simple calculations to assure safety from criticality. Experimental measurements and computer code calculations of criticality are discussed. To emphasize the reality, historical criticality accidents are presented in a table with major ones discussed to provide lessons-learned. Finally, standards, NRC guides and regulations, and DOE orders relating to criticality protection are presented.

    In order to enhance the quality of integration of physiological basic concepts with clinical sciences and to facilitate problem solving skills, a 'structured integrated interactive' two-hour block lecture on growth hormone physiology was implemented. A template showing the central regulation of growth hormone release and its peripheral effects was developed as an advanced organizer. Based on this template, new information was presented. Student feedback demonstrated that the lecture, based on the expository teaching model and enhanced by different forms of question and problem solving activities, was successful and interactive. It was also more motivating and was able to keep the attention of the students in relatively higher levels throughout the lecture. Furthermore, students felt that they had made important gains in transferable problem solving skills and this opinion was supported by their performance in clinical cases. These findings reinforced the idea that systematic incorporation of active learning strategies into lectures may minimize many of the weaknesses of traditional lectures.

  12. William D. Hamilton's Brazilian lectures and his unpublished model regarding Wynne-Edwards's idea of natural selection. With a note on 'pluralism' and different philosophical approaches to evolution.

    PubMed

    Coco, Emanuele

    2016-12-01

    In 1975, the English evolutionist William Donald Hamilton (1936-2000) held in Brazil a series of lectures entitled "Population genetics and social behaviour". The unpublished notes of these conferences-written by Hamilton and recently discovered at the British Library-offer an opportunity to reflect on some of the author's ideas about evolution. The year of the conference is particularly significant, as it took place shortly after the applications of the Price equation with which Hamilton was able to build a model that included several levels of selection. In this paper I mainly analyse the inaugural lecture in which Hamilton proposes a simple model to disprove the hypothesis supported by the British zoologist C. Vero Wynne-Edwards (1906-1997) regarding mechanisms to prevent "over-exploitation of the food supply" in "the interests of the survival of the group". The document presented here is of great historical interest. Not only because manuscript offers a model that-since it was intended for teaching purposes-had never before appeared in the published version, but also because of the general index of the lectures that accompanies it. The latter allows us to make some hypothetical considerations on the relationship and differences between kin-selection, group-selection and inclusive fitness that Hamilton wanted to present to the attentive, well-prepared audience of the foreign university that had invited him.

  13. Lectures on Yangian symmetry

    NASA Astrophysics Data System (ADS)

    Loebbert, Florian

    2016-08-01

    In these introductory lectures we discuss the topic of Yangian symmetry from various perspectives. Forming the classical counterpart of the Yangian and an extension of ordinary Noether symmetries, first the concept of nonlocal charges in classical, two-dimensional field theory is reviewed. We then define the Yangian algebra following Drinfel’d's original motivation to construct solutions to the quantum Yang-Baxter equation. Different realizations of the Yangian and its mathematical role as a Hopf algebra and quantum group are discussed. We demonstrate how the Yangian algebra is implemented in quantum, two-dimensional field theories and how its generators are renormalized. Implications of Yangian symmetry on the two-dimensional scattering matrix are investigated. We furthermore consider the important case of discrete Yangian symmetry realized on integrable spin chains. Finally we give a brief introduction to Yangian symmetry in planar, four-dimensional super Yang-Mills theory and indicate its impact on the dilatation operator and tree-level scattering amplitudes. These lectures are illustrated by several examples, in particular the two-dimensional chiral Gross-Neveu model, the Heisenberg spin chain and { N }=4 superconformal Yang-Mills theory in four dimensions.

  14. Analysis of Students' Eye Movement in Relation to Contents of Multimedia Lecture

    In this article, we report our analysis of how the students' eye movement is affected by the content of lecture in order to utilize as standard of selection of image for distance learning and WBT. We classified content of lecture into nine parts: introduction, presentation, explanation, illustration, assertion, query, reply, question, response.We analyzed students' eye movement in the multimedia lecture "Japanese Economics", which was distance lecture between Kyoto University and UCLA. As the result of analysis, we get the following characteristic of eye movement of each course process in practical lecture.Introduction; students gaze at lecturer at first in order to achieve advance organizer, and next look at material.Presentation; they mainly stare at material and sometimes peer at lecturer to complement lack of understanding with information given by lecturer.Explanation; staring time is longer than other course process categories, and students stare at the object which they regard as important.Illustration; students stare at material which offers main information source.Assertion; they gaze at lecturer because of interaction between lecturer and students.Question-and-answer; generally students look at speaker but in the case of "query" about material, they change their focuses on material and lecturer fast and by turns in order to get information of lecturer and material.And our research suggests the practical guide for our choice of image information.

  2. 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.

    From the Newsline Editor: The Highlights Lecture, presented at the closing session of each SNMMI Annual Meeting, was originated and delivered for more than 30 years by Henry N. Wagner, Jr., MD. Beginning in 2010, the duties of summarizing selected significant presentations at the meeting were divided annually among 4 distinguished nuclear and molecular medicine subject matter experts. The 2015 Highlights Lectures were delivered on June 10 at the SNMMI Annual Meeting in Baltimore, MD. Umar Mahmood, MD, PhD, a professor of radiology at Massachusetts General Hospital (Boston, MA), spoke on oncology highlights from the meeting’s sessions. Because of its length, the oncology presentation will be divided between 2 Newsline issues.

  4. Responsive, Flexible and Scalable Broader Impacts (Invited)

    NASA Astrophysics Data System (ADS)

    Decharon, A.; Companion, C.; Steinman, M.

    2010-12-01

    In many educator professional development workshops, scientists present content in a slideshow-type format and field questions afterwards. Drawbacks of this approach include: inability to begin the lecture with content that is responsive to audience needs; lack of flexible access to specific material within the linear presentation; and “Q&A” sessions are not easily scalable to broader audiences. Often this type of traditional interaction provides little direct benefit to the scientists. The Centers for Ocean Sciences Education Excellence - Ocean Systems (COSEE-OS) applies the technique of concept mapping with demonstrated effectiveness in helping scientists and educators “get on the same page” (deCharon et al., 2009). A key aspect is scientist professional development geared towards improving face-to-face and online communication with non-scientists. COSEE-OS promotes scientist-educator collaboration, tests the application of scientist-educator maps in new contexts through webinars, and is piloting the expansion of maps as long-lived resources for the broader community. Collaboration - COSEE-OS has developed and tested a workshop model bringing scientists and educators together in a peer-oriented process, often clarifying common misconceptions. Scientist-educator teams develop online concept maps that are hyperlinked to “assets” (i.e., images, videos, news) and are responsive to the needs of non-scientist audiences. In workshop evaluations, 91% of educators said that the process of concept mapping helped them think through science topics and 89% said that concept mapping helped build a bridge of communication with scientists (n=53). Application - After developing a concept map, with COSEE-OS staff assistance, scientists are invited to give webinar presentations that include live “Q&A” sessions. The webinars extend the reach of scientist-created concept maps to new contexts, both geographically and topically (e.g., oil spill), with a relatively small

    NASA Astrophysics Data System (ADS)

    Douglas, Scott Samuel; Aiken, John Mark; Greco, Edwin; Schatz, Michael; Lin, Shih-Yin

    2017-01-01

    Video lectures are increasingly being used in physics instruction. For example, video lectures can be used to "flip" the classroom, i.e., to deliver, via the Internet, content that is traditionally transmitted by in-class lectures (e.g., presenting concepts, working examples, etc.), thereby freeing up classroom time for more interactive instruction. To date, most video lectures are live lecture recordings or screencasts. The hand-animated "whiteboard" video is an alternative to these more common styles and affords unique creative opportunities such as stop-motion animation or visual "demonstrations" of phenomena that would be difficult to demo in a classroom. In the spring of 2013, a series of whiteboard-style videos were produced to provide video lecture content for Georgia Tech introductory physics instruction, including flipped courses and a MOOC. This set of videos (which also includes screencasts and live recordings) can be found on the "Your World is Your Lab" YouTube channel. In this article, we describe this method of video production, which is suitable for an instructor working solo or in collaboration with students; we explore students' engagement with these videos in a separate work. A prominent example of whiteboard animation is the "Minute Physics" video series by Henry Reich, whose considerable popularity and accessible, cartoony style were the original inspiration for our own video lectures.

    Milner-Bolotin, Marina M.; Kotlicki, A.; Rieger, G.; Bates, F.; Moll, R.; McPhee, K.; Nashon, S.

    2006-12-01

    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).

  10. Introductory lecture: nanoplasmonics.

    PubMed

    Brongersma, Mark L

    2015-01-01

    Nanoplasmonics or nanoscale metal-based optics is a field of science and technology with a tremendously rich and colourful history. Starting with the early works of Michael Faraday on gold nanocolloids and optically-thin gold leaf, researchers have been fascinated by the unusual optical properties displayed by metallic nanostructures. We now can enjoy selecting from over 10 000 publications every year on the topic of plasmonics and the number of publications has been doubling about every three years since 1990. This impressive productivity can be attributed to the significant growth of the scientific community as plasmonics has spread into a myriad of new directions. With 2015 being the International Year of Light, it seems like a perfect moment to review some of the most notable accomplishments in plasmonics to date and to project where the field may be moving next. After discussing some of the major historical developments in the field, this article will analyse how the most successful plasmonics applications are capitalizing on five key strengths of metallic nanostructures. This Introductory Lecture will conclude with a brief look into the future.

    The Shapley Lectureships are both an honor and a privilege. The program has long provided the non-specialist a rare glimpse of the latest result of astronomical investigations. Shapley Lecturers carry the banner for the most interesting of all the sciences. They share the beauty and strength of astronomy by representing the discipline to non-specialists. It is important that we contribute what we can to this program. One might benefit from the frequent travel of most astronomers. Most research trips are now covered by grant money, by university money, and by Government money. Leverage this travel. For example, many meetings are held near places with small colleges. Consider sending a Shapley brochure to the science departments before your trip. Such trips may often be used to elicit a Shapley visit. Advertise the program. When we talk about astronomy to others we help all of us to keep this science alive. I will share the results of my Shapley Visits made in the last four years while traveling for NASA and NSF.

    1987-01-01

    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.

  14. Using active learning in lecture: best of "both worlds".

    PubMed

    Oermann, Marilyn H

    2004-01-01

    Many creative teaching strategies have been developed in recent years in nursing and other fields to promote active learning. These strategies foster development of problem solving, critical thinking, and communication skills, and they encourage students to work collaboratively with peers. However, in nurse educators' rush to embrace active learning, lecture has been viewed negatively by some faculty. Rather than positioning active learning against lecture, another approach is to integrate active learning within lecture, gaining the benefits of both methods. An integrated approach also takes into consideration the situation of teaching large groups of students. This article examines benefits of an integrated approach to teaching and presents strategies for active learning intended for use with lecture.

  15. The Trieste Lecture of John Stewart Bell

    Bassi, Angelo; Carlo Ghirardi, Gian

    2007-03-01

    Delivered at Trieste on the occasion of the 25th Anniversary of the International Centre for Theoretical Physics, 2 November 1989 The video of this lecture is available here. Please see the PDF for the transcript of the lecture. General remarks by Angelo Bassi and GianCarlo Ghirardi During the autumn of 1989 the International Centre for Theoretical Physics, Trieste, celebrated the 25th anniversary of its creation. Among the many prestigious speakers, who delivered extremely interesting lectures on that occasion, was the late John Stewart Bell. All lectures have been recorded on tape. We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization. When the two meetings Are there quantum jumps? and On the present status of Quantum Mechanics were organized in Trieste and Losinj (Croatia), on 5 10 September 2005, it occurred to us that this lecture, which has never been published, might represent an

  15. Attention span during lectures: 8 seconds, 10 minutes, or more?

    PubMed

    Bradbury, Neil A

    2016-12-01

    In the current climate of curriculum reform, the traditional lecture has come under fire for its perceived lack of effectiveness. Indeed, several institutions have reduced their lectures to 15 min in length based upon the "common knowledge" and "consensus" that there is a decline in students' attention 10-15 min into lectures. A review of the literature on this topic reveals many discussions referring to prior studies but scant few primary investigations. Alarmingly, the most often cited source for a rapid decline in student attention during a lecture barely discusses student attention at all. Of the studies that do attempt to measure attention, many suffer from methodological flaws and subjectivity in data collection. Thus, the available primary data do not support the concept of a 10- to 15-min attention limit. Interestingly, the most consistent finding from a literature review is that the greatest variability in student attention arises from differences between teachers and not from the teaching format itself. Certainly, even the most interesting material can be presented in a dull and dry fashion, and it is the job of the instructor to enhance their teaching skills to provide not only rich content but also a satisfying lecture experience for the students.

  14. Lectures on Matrix Field Theory

    NASA Astrophysics Data System (ADS)

    Ydri, Badis

    The subject of matrix field theory involves matrix models, noncommutative geometry, fuzzy physics and noncommutative field theory and their interplay. In these lectures, a lot of emphasis is placed on the matrix formulation of noncommutative and fuzzy spaces, and on the non-perturbative treatment of the corresponding field theories. In particular, the phase structure of noncommutative $\\phi^4$ theory is treated in great detail, and an introduction to noncommutative gauge theory is given.

  15. Three Lectures on Hadron Physics

    NASA Astrophysics Data System (ADS)

    Roberts, Craig D.

    2016-04-01

    These lectures explain that comparisons between experiment and theory can expose the impact of running couplings and masses on hadron observables and thereby aid materially in charting the momentum dependence of the interaction that underlies strong-interaction dynamics. The series begins with a primer on continuum QCD, which introduces some of the basic ideas necessary in order to understand the use of Schwinger functions as a nonperturbative tool in hadron physics. It continues with a discussion of confinement and dynamical symmetry breaking (DCSB) in the Standard Model, and the impact of these phenomena on our understanding of condensates, the parton structure of hadrons, and the pion electromagnetic form factor. The final lecture treats the problem of grand unification; namely, the contemporary use of Schwinger functions as a symmetry-preserving tool for the unified explanation and prediction of the properties of both mesons and baryons. It reveals that DCSB drives the formation of diquark clusters in baryons and sketches a picture of baryons as bound-states with Borromean character. Planned experiments are capable of validating the perspectives outlined in these lectures.

  17. Proposal for research and education: joint lectures and practicals on central nervous system anatomy and physiology.

    PubMed

    Kageyama, Ikuo; Yoshimura, Ken; Satoh, Yoshihide; Nanayakkara, Chinthani D; Pallegama, Ranjith W; Iwasaki, Shin-Ichi

    2016-07-01

    We coordinated anatomy and physiology lectures and practicals to facilitate an integrated understanding of morphology and function in a basic medical science program for dental students and to reduce the time spent on basic science education. This method is a means to provide the essential information and skills in less time. The overall impression was that the practice of joint central nervous system lectures and practicals was an efficient method for students, which suggests that joint lectures might also be useful for clinical subjects. About two-thirds of students felt that the joint anatomy and physiology lecture on the central nervous system was useful and necessary in understanding the relationship between morphology and function, at least for this subject. One-third of students were neutral on the effectiveness of this method. However, the survey results suggest that improvements are needed in the method and timing of joint lectures and practicals. The present teaching approach can be further improved by conducting combined lectures in which the form and function of anatomic structures are presented by the relevant departments during the same lecture. Finally, joint lecturers and practicals offer an opportunity to increase student understanding of the importance of new research findings by the present authors and other researchers.

  18. Textbook images: how do they invite students into physics?

    NASA Astrophysics Data System (ADS)

    Bungum, Berit

    2013-09-01

    This paper presents a study of images in Norwegian physics textbooks for upper secondary school, and how they invite students into physics by means of visual communication. The concept of ‘framing’ is used to investigate how the perspective in the image provides a sense of participation. It is found that older textbooks, where objects and experimental setups dominate the images, involve the reader in terms of weak framing. This is to some degree resembled in newer textbooks with the increased use of photographs of learners in some physics activity. This does, however, invite the learner into school physics rather than professional physics. Connections made to physics in society and everyday life in images can also be seen as inviting the learner into physics, by exhibiting how modern physicists work and by referring to the relevance of physics, respectively.

    2005-01-01

    Replicating large eukaryotic genomes presents the challenge of distinguishing replicated regions of DNA from unreplicated DNA. A heterohexamer of minichromosome maintenance (MCM) proteins is essential for the initiation of DNA replication. MCM proteins are loaded on to unreplicated DNA before replication begins and displaced progressively during replication. Thus, bound MCM proteins license DNA for one, and only one, round of replication and this licence is reissued each time a cell divides. MCM proteins are also the best candidates for the replicative helicases that unwind DNA during replication, but interesting questions arise about how they can perform this role, particularly as they are present on only unreplicated DNA, rather than clustered at replication forks. Although MCM proteins are bound and released cyclically from DNA during the cell cycle, higher eukaryotic cells retain them in the nucleus throughout the cell cycle. In contrast, MCMs are broken down when cells exit the cycle by quiescence or differentiation. We have exploited these observations to develop screening tests for the common carcinomas, starting with an attempt to improve the sensitivity of the smear test for cervical cancer. MCM proteins emerge as exceptionally promising markers for cancer screening and early diagnosis. PMID:16147513

  20. Lecture capturing assisted teaching and learning experience

    NASA Astrophysics Data System (ADS)

    Chen, Li

    2015-03-01

    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.

    PubMed

    O'Connor, G R

    1985-01-01

    Fuchs' heterochromic iridocyclitis is a rare but significant cause of visual impairment. This form of uveitis is misdiagnosed more than any other in the entire field of uveitis. This is particularly true among brown-eyed individuals in whom gross heterochromia may not be diagnosed for many years. The clinical presentation of Fuchs' heterochromic iridocyclitis may include a number of generally unrecognised variants among which are Koeppe nodules, transient synechia formations, and blood-filled cysts. Recently the relationship of heterochromic iridocyclitis to posterior inflammatory lesions, such as those of toxoplasmosis, has been explored. Although the disease was once thought to be a degenerative or trophic disorder, current investigations reveal that it is a true inflammation of immunologic origin. The disorder may be related to a depression of suppressor T-cell activity. The aetiology of the disease is still obscure, but in some cases an association with simple heterochromia has been found among families in whom multiple members are affected by either simple heterochromia or Fuchs' heterochromic iridocyclitis. Corticosteroid treatment of Fuchs' heterochromic iridocyclitis is not effective and should be reserved for those patients in whom inflammatory products obstruct the visual axis. Most patients should be treated by observation alone. Cataract and glaucoma are the most important complications. Treatment of the glaucoma is particularly difficult and often unsuccessful.

    The physiology of paracellular permeation of ions and solutes in the kidney is pivotally important but poorly understood. Claudins are the key components of the paracellular pathway. Defects in claudin function result in a broad range of renal diseases, including hypomagnesemia, hypercalciuria and nephrolithiasis. This review describes recent findings on the physiological function of claudins underlying paracellular transport mechanisms with a focus on renal Ca2+ handling. We have uncovered a molecular mechanism underlying paracellular Ca2+ transport in the thick ascending limb of Henle (TAL) that involves the functional interplay of three important claudin genes: claudin-14, -16 and -19, all of which are associated with human kidney diseases with hypercalciuria, nephrolithiasis and bone mineral loss. The Ca2+ sensing receptor (CaSR) signaling in the kidney has long been a mystery. By analyzing small non-coding RNA molecules in the kidney, we have uncovered a novel microRNA based signaling pathway downstream of CaSR that directly regulates claudin-14 gene expression and establishes the claudin-14 molecule as a key regulator for renal Ca2+ homeostasis. The molecular cascade of CaSR-microRNAs-claudins forms a regulatory loop to maintain proper Ca2+ homeostasis in the kidney. PMID:22504740

    The 100 ns, 20 MA pinch-driver Z is surrounded by an extensive set of diagnostics. There are nine radial lines of sight set at 12° above horizontal and each of these may be equipped with up to five diagnostic ports. Instruments routinely fielded viewing the pinch from the side with these ports include x-ray diode arrays, photoconducting detector arrays, bolometers, transmission grating spectrometers, time-resolved x-ray pinhole cameras, x-ray crystal spectrometers, calorimeters, silicon photodiodes, and neutron detectors. A diagnostic package fielded on axis for viewing internal pinch radiation consists of nine lines of sight. This package accommodates virtually the same diagnostics as the radial ports. Other diagnostics not fielded on the axial or radial ports include current B-dot monitors, filtered x-ray scintillators coupled by fiber optics to streak cameras, streaked visible spectroscopy, velocity interferometric system for any reflector, bremsstrahlung cameras, and active shock breakout measurement of hohlraum temperature. The data acquisition system is capable of recording up to 500 channels and the data from each shot is available on the Internet. A major new diagnostic presently under construction is the BEAMLET backlighter. We will briefly describe each of these diagnostics and present some of the highest-quality data from them.

  2. Adult Learning Principles and Presentation Pearls

    PubMed Central

    Palis, Ana G.; Quiros, Peter A.

    2014-01-01

    Although lectures are one of the most common methods of knowledge transfer in medicine, their effectiveness has been questioned. Passive formats, lack of relevance and disconnection from the student's needs are some of the arguments supporting this apparent lack of efficacy. However, many authors have suggested that applying adult learning principles (i.e., relevance, congruence with student's needs, interactivity, connection to student's previous knowledge and experience) to this method increases learning by lectures and the effectiveness of lectures. This paper presents recommendations for applying adult learning principles during planning, creation and development of lectures to make them more effective. PMID:24791101

    This study investigates the gaze patterns of undergraduate college students attending a lecture-based physical science class to better understand the relationships between gaze and focus patterns and student attention during class. The investigators used a new eye-tracking product; Tobii Glasses. The glasses eliminate the need for subjects to focus on a computer screen or carry around a backpack-sized recording device, thus giving an investigator the ability to study a broader range of research questions. This investigation includes what students focus on in the classroom (i.e. demonstrations, instructor, notes, board work, and presentations) during a normal lecture, what diverts attention away from being on task as well as what keeps a subject on task. We report on the findings from 8 subjects during physical science lectures designed for future elementary school teachers. We found that students tended not to focus on the instructor for most parts of the lecture but rather the information, particularly new information presented on PowerPoint slides. Finally, we found that location in the classroom also impacted students' attention spans due to more distractors.

  4. Creationism & Climate Change (Invited)

    Although creationists focus on the biological sciences, recently creationists have also expanded their attacks to include the earth sciences, especially on the topic of climate change. The creationist effort to deny climate change, in addition to evolution and radiometric dating, is part of a broader denial of the methodology and validity of science itself. Creationist misinformation can pose a serious problem for science educators, who are further hindered by the poor treatment of the earth sciences and climate change in state science standards. Recent changes to Texas’ science standards, for example, require that students learn “different views on the existence of global warming.” Because of Texas’ large influence on the national textbook market, textbooks presenting non-scientific “different views” about climate change—or simply omitting the subject entirely because of the alleged “controversy”—could become part of K-12 classrooms across the country.

  5. Lectures on Dark Matter Physics

    NASA Astrophysics Data System (ADS)

    Lisanti, Mariangela

    Rotation curve measurements from the 1970s provided the first strong indication that a significant fraction of matter in the Universe is non-baryonic. In the intervening years, a tremendous amount of progress has been made on both the theoretical and experimental fronts in the search for this missing matter, which we now know constitutes nearly 85% of the Universe's matter density. These series of lectures provide an introduction to the basics of dark matter physics. They are geared for the advanced undergraduate or graduate student interested in pursuing research in high-energy physics. The primary goal is to build an understanding of how observations constrain the assumptions that can be made about the astro- and particle physics properties of dark matter. The lectures begin by delineating the basic assumptions that can be inferred about dark matter from rotation curves. A detailed discussion of thermal dark matter follows, motivating Weakly Interacting Massive Particles, as well as lighter-mass alternatives. As an application of these concepts, the phenomenology of direct and indirect detection experiments is discussed in detail.

  6. The oral medicoscientific presentation: art, entertainment, or science -- all, some, or none? A brief guide for presenters (and moderators)

    2003-12-01

    The summons from a medical congress or symposium chairman, chairwoman or president to be a session moderator or to deliver an invited lecture, or the offer to participate in a free paper session are events which can turn the most seasoned clinician and researcher into something which lies on the bed of the ocean and shivers, namely, a nervous wreck. However, proper planning and the following of a few simple rules can eliminate the mental trauma for the presenter often wrongly associated with having to give an oral presentation, and indeed obviate the sometimes much more serious trauma inflicted upon the hapless audience by an ill-prepared presentation and a hapless presenter, not to mention a mutinous moderator. The first point is that an oral presentation is not a scientific paper, and therefore while it may follow in general the usual divisions of a written article, it should not be a pictorial representation of a piece of rigid scientific writing. Secondly, presenters are almost always given a time limit for their presentation. It is the height of bad manners and total ignorance to exceed this time limit, as the presenter is often one of a series.

    2013-01-01

    Increasing application of information technology including web-based lectures and live-lecture recording appears to have many advantages for undergraduate nursing education. These include greater flexibility, opportunity for students to review content on demand and the improved academic management of increasing class sizes without significant increase in physical infrastructure. This study performed a quasi-experimental comparison between two groups of nursing students undertaking their first anatomy and physiology course, where one group was also provided access to streaming of recorded copies of the live lectures and the other did not. For the course in which recorded lectures were available student feedback indicated overwhelming support for such provision with 96% of students having accessed recorded lectures. There was only a weak relationship between access of recorded lectures and overall performance in the course. Interestingly, the nursing students who had access to the recorded lectures demonstrated significantly poorer overall academic performance (P < 0.001). Although this study did not specifically control for student demographics or other academic input, the data suggests that provision of recorded lectures requires improved and applied time management practices by students and caution on the part of the academic staff involved.

  15. Probing the Effectiveness of the Conventional Introductory Science Lecture

    NASA Astrophysics Data System (ADS)

    Slater, T. F.; Prather, E. E.

    2003-12-01

    For quite some time now, the repeated call for a more student-centered approach to teaching due to the ineffectiveness of lecture has been gaining prominence in the earth and space science teaching community. However, our extensive review of the literature suggests that this claim of ineffectiveness of lecture has not been validated in the context of the conventional introductory science course for non-science majors. At the beginning of a large-enrollment introductory astronomy survey course, we administered 68-multiple choice items as a pretest to 81 students. At the end of each lecture we administered the specific items related to that particular day's lecture a second time as a posttest. The average score on the 68 items administered as a pretest was 30 percent correct and the posttest average score was 52 percent correct. Although this does represent a statistically significant gain in scores, we judge this level of success to be insufficient for long term learning achievement. These results illustrate that instructor-centered strategies are largely ineffective at promoting meaningful conceptual gains on traditional earth and space topics presented to non-science majors. This work was supported by NSF CCLI #9952232 and NSF Geosciences Education #9907755.

  16. Just do it: flipped lecture, determinants and debate

    NASA Astrophysics Data System (ADS)

    Kensington-Miller, Barbara; Novak, Julia; Evans, Tanya

    2016-08-01

    This paper describes a case study of two pure mathematicians who flipped their lecture to teach matrix determinants in two large mathematics service courses (one at Stage I and the other at Stage II). The purpose of the study was to transform the passive lecture into an active learning opportunity and to introduce valuable mathematical skills, such as debate, argument and disagreement. The students were told in advance to use the online material to prepare, which had a short handout on matrix determinants posted, as the lesson would be interactive and would rely on them having studied this. At the beginning of the lesson, the two mathematicians worked together to model the skill of professional disagreement, one arguing for the cofactor expansion method and the other for the row reduction method. After voting for their preferred method, the students worked in small groups on examples to defend their choice. Each group elected a spokesperson and a political style debate followed as the students argued the pros and cons of each technique. Although one lecture does not establish whether the flipped lecture model is preferable for student instruction, the paper presents a case study for pursuing this approach and for further research on incorporating this style of teaching in Science, Technology, Engineering and Mathematics subjects.

    1996-06-01

    The subject of quantum electrodynamics (QED) was the subject of QED—The Strange Theory of Light and Matter, the popular book by Richard Feynman which was published by Princeton University Press in 1985. On p. 1, Feynman makes passing reference to the fact that the book is based on a series of general lectures on QED which were, however, first delivered in New Zealand. At Auckland University, these lectures were delivered in 1979, as the Sir Douglas Robb lectures, and videotapes of the lectures are held by the Auckland University Physics Department. We have carried out a detailed examination of these videotapes, and we discuss here the major differences between the original Auckland lectures and the published version. We use selected quotations from the lectures to show that the original lectures provide additional insight into Feynman's character, and have great educational value.

  20. [THE DISCUSSION CONCERNING THE PLACE OF LECTURES AND COMPULSORY LECTURE ATTENDANCE IN MEDICAL EDUCATION].

    PubMed

    Reis, Shmuel

    2016-04-01

    Luder shows that there is a lack of correlation between lecture attendance in medical school and examination performance, and thus draws attention to a discourse concerning the place of lectures and lecture attendance enforcement in 2015 and beyond. The paper addresses 4 questions: First, what is the current place of the traditional lecture in the education of medical students? Second, are there alternatives to this format of teaching? Third, what are the educational consequences of mandating lecture attendance; and fourth, should there be such enforcement? The author discusses these questions and concludes that lectures should be used sparingly, after a careful evaluation that they have an added value over learning away from the classroom. Furthermore, that there are clear guidelines on how to make the traditional lecture enhanced and educationally effective, as well as alternatives such as the "flipped classroom", e-learning and more to lectures. In addition, that lectures frequently drive learning negatively and enforcing attendance in Israel entails serious unintended consequences such as a need to monitor attendance, and a host of disciplinary adverse reactions. Finally, that besides lecture efficiency and economy (when having added value) one reason to consider compulsory attendance, may be when poor attendance negatively influences teachers morale.

    2016-01-01

    Objective: The objective of this study was to evaluate the academic impact of cooperative peer instruction during lecture pauses in an immunology/endocrinology course. Methods: Third-quarter students participated across iterations of the course. Each class offered 20 lectures of 50 minutes each. Classes were divided into a peer-instruction group incorporating cooperative peer instruction and a control group receiving traditional lectures. Peer-instruction group lectures were divided into 2–3 short presentations followed by a multiple-choice question (MCQ). Students recorded an initial answer and then had 1 minute to discuss answers with group peers. Following this, students could submit a revised answer. The control group received the same lecture material, but without MCQs or peer discussions. Final-exam scores were compared across study groups. A mixed-design analysis of covariance was used to analyze the data. Results: There was a statistically significant main effect for the peer-instruction activity (F(1, 93) = 6.573, p = .012, r = .257), with recall scores higher for MCQs asked after peer-instruction activities than for those asked before peer instruction. Final-exam scores at the end of term were greater in the peer-instruction group than the control group (F(1, 193) = 9.264, p = .003, r = .214; question type, F(1, 193) = 26.671, p = .000, r = .348). Conclusion: Lectures with peer-instruction pauses increase student recall and comprehension compared with traditional lectures. PMID:26967766

  11. Making lectures memorable: A cognitive perspective.

    PubMed

    Afzal, Azam; Babar, Shazia

    2016-08-01

    Lectures have been a cornerstone of medical education since the introduction of a discipline based curricular model more than two hundred years ago. Recently this instructional strategy has come under criticism because of its reliance on passive learning. There are still many medical schools that cover content predominantly through lectures due to its feasibility. With the introduction of the flipped classrooms, lectures have been given a new lease of life. Improving cognitive imprinting during lectures would enhance retrieval and promote long term storage. Simplifying the content reduces the cognitive load of the information being received and makes it more meaningful hence more memorable. To make learning memorable, rehearsal should be built into the sessions. With the exponential increase in online learning, the need for online learning technologies will require a generation of a large amount of asynchronous video content which should ideally be truly meaningful and memorable, and inspirational to our students.

  3. Lectures on probability and statistics

    SciTech Connect

    Yost, G.P.

    1984-09-01

    These notes are based on a set of statistics lectures delivered at Imperial College to the first-year postgraduate students in High Energy Physics. They are designed for the professional experimental scientist. We begin with the fundamentals of probability theory, in which one makes statements about the set of possible outcomes of an experiment, based upon a complete a priori understanding of the experiment. For example, in a roll of a set of (fair) dice, one understands a priori that any given side of each die is equally likely to turn up. From that, we can calculate the probability of any specified outcome. We finish with the inverse problem, statistics. Here, one begins with a set of actual data (e.g., the outcomes of a number of rolls of the dice), and attempts to make inferences about the state of nature which gave those data (e.g., the likelihood of seeing any given side of any given die turn up). This is a much more difficult problem, of course, and one's solutions often turn out to be unsatisfactory in one respect or another.

    Teaching and learning activities in the dental clinic or hospital are a challenging area for students as well as teachers. With various teaching methodologies being used in dental schools around the world, gaining greater understanding of students' attitudes toward these methodologies would be useful for dental educators. The objective of this study was to explore the preferences of dental students in India about various aspects of lecture courses. A structured survey consisting of ten closed-ended questions was developed, and 2,680 undergraduate students from forty-three dental schools in India were approached via e-mail with a follow-up postal mailing. Of these, 1,980 students responded, for a response rate of 73.8 percent. Most of the students reported preferring lectures with the aid of PowerPoint and chalkboard. They preferred morning lectures from 8 am to 10 am for a maximum of thirty to forty minutes for each lecture, and they preferred to receive information about the lecture topic in advance. The students said that delivery of clinical demonstrations was beneficial after the lectures, and they preferred learning-based rather than exam-oriented education. The respondents also said that attendance should be made compulsory and that numerical marking of examinations should not be replaced by a grading system.

    A fuzzy evolutionary algorithm is an integration of an evolutionary algorithm and a fuzzy system. In this paper, we present an application of a genetic algorithm to a fuzzy evolutionary algorithm to detect and to solve chromosomes conflict. A chromosome conflict is identified by existence of any two genes in a chromosome that has the same values as two genes in another chromosome. Based on this approach, we construct an algorithm to solve a lecture scheduling problem. Time codes, lecture codes, lecturer codes, and room codes are defined as genes. They are collected to become chromosomes. As a result, the conflicted schedule turns into chromosomes conflict. Built in the Delphi program, results show that the conflicted lecture schedule problem is solvable by this algorithm.

  9. A novice teacher's reflections on lecturing as a teaching strategy: covering the content or uncovering the meaning.

    PubMed

    Clynes, Mary P

    2009-01-01

    The lecture is the most widely used teaching strategy in adult education programmes. While it has advantages, it is criticised for its lack of student engagement and inability to stimulate higher-order thinking. The aim of this paper is to detail a novice teacher's journey using the lecture as a teaching strategy. The use of an action research approach provided the teacher with a framework to research own learning. In addition, the collaborative process inherent in action research resulted in students being invited to evaluate the teaching. The journey takes the teacher from a teacher-centred approach to teaching and learning to a student-centred approach. The influence of the teacher's own educational encounters is explored. In common with many novice teachers, the focus on content delivery and difficulty asking questions are two key issues. The gradual implementation of strategies to allow for more student engagement is discussed and advice is offered to the novice teacher.

    This study tested the possibility that interactive lectures explicitly based on activating learners' prior knowledge and driven by a series of logical questions might enhance the effectiveness of lectures. A class of 54 students doing the respiratory system course in the second year of the Bachelor of Medicine and Bachelor of Surgery program in my university was randomized to two groups to receive one of two types of lectures, "typical" lectures (n = 28, 18 women and 10 men) or "constructivist" lectures (n = 26, 19 women and 7 men), on the same topic: the regulation of respiration. Student pretest scores in the two groups were comparable (P > 0.1). Students that received the constructivist lectures did much better in the posttest conducted immediately after the lectures (6.8 +/- 3.4 for constructivist lectures vs. 4.2 +/- 2.3 for typical lectures, means +/- SD, P = 0.004). Although both types of lectures were well received, students that received the constructivist lectures appeared to have been more satisfied with their learning experience. However, on a posttest conducted 4 mo later, scores obtained by students in the two groups were not any different (6.9 +/- 3 for constructivist lectures vs. 6.9 +/- 3.7 for typical lectures, P = 0.94). This study adds to the increasing body of evidence that there is a case for the use of interactive lectures that make the construction of knowledge and understanding explicit, easy, and enjoyable to learners.

    2017-03-01

    A cohort of first-year biology students was surveyed regarding their opinions and viewing habits for live and recorded lectures. Most respondents (87%) attended live lectures as a rule (attenders), with 66% attending more than two-thirds of the lectures. In contrast, only 52% accessed recordings and only 13% viewed more than two-thirds of the available recordings. Respondents regarded lectures as efficient for information delivery (75%), and 89% enjoyed live lectures because they were useful for learning (89%), understanding coursework (94%), and keeping up with the subject (93%). Lecture enjoyment was driven less by entertainment (34%) or interaction with the lecturers (47%), although most students preferred an entertaining lecturer to a factual expert (72%). Exam marks were positively correlated with the number of lectures attended (P < 0.001) and negatively correlated with the number of recordings viewed (P < 0.05), although marks were similar for lecture attenders and nonattenders (P > 0.05). Lecture attenders mostly missed lectures to complete assessments during the same week (68%), whereas nonattenders were more likely to miss lectures due to outside commitments or preference for study from books or recorded lectures (P < 0.001). Recordings were used to replace missed lectures (64%), rather than for revision, and were viewed mostly alone (96%) in one sitting (65%). Only 22% of respondents agreed that some lectures could be replaced by recordings, but 59% agreed with having some videoconference lectures from experts on another campus. Overall, this cohort showed a clear preference for live lectures over recordings, with limited support for synchronous videoconference lectures.

    Visibility of different kinds is important in academic work. We publish papers, present results at conferences and are invited to give seminars and write contributions and reviews about other scientists' work. A few years back we reacted on the invitation-only sections in two of the leading scientific journals. We asked: "Who are invited to write about other researchers' newly published results?" The short answer could be: Experts in the field. However, we found that it was mainly male experts in the field when we reviewed/categorized the authors of the invitation-only sections News & Views and Perspective in Nature and Science, respectively, during the years 2010 and 2011 (in total 1663 authors). The proportion of female authors was compared to the proportion of female scientists within their respective fields within academia. We found that female scientists were invited less often than their male colleagues. We notified the two journals about the mismatch (Nature 2012: 488) and their encouraging reply was that they needed to improve how they reflect women's contributions to science (Nature 2012: 491). In 2013 and 2014 the invitation-only sections (with in total 1845 authors) had reached parity (compared to the pool of available scientists) for contributions regarding Earth and Environmental Science, and made steps forward for Medical/Biological/Chemical sciences and Physical sciences. By raising awareness about the unconscious biases we all have, e.g. both men and women, we can act to make progress towards parity in science.

  15. Using Lecture Tutorials to Increase Student Learning in Introductory Geoscience Courses

    NASA Astrophysics Data System (ADS)

    2007-12-01

    Students often leave introductory geoscience courses with their misconceptions still intact, and we developed Lecture Tutorials (LTs) to help alleviate this problem. LTs are 10-15 minute interactive worksheets that students complete in small groups in class, after a short introductory lecture. Topics for the LTs (e.g., climate change, the rock cycle, etc.) were chosen because they are commonly taught in introductory classes and include recognized misconceptions. The LTs typically follow a sequence beginning with factual-based questions that progressively become more difficult and culminating in application-type questions designed to provoke both discussion and critical thinking. Often, one of the latter questions is presented in the form of a debate between two students, where one student expresses the scientifically held view and the other espouses a view based on a common misconception. Students in the class must determine with which student in the LT they agree and explain why. These hypothetical debates allow students to confront their own misconceptions and replace them with the accepted scientific views. Lecture Tutorials increase student learning more than lectures alone. After a short lecture, students correctly answered 58% of multiple-choice questions (including embedded Geoscience Concept Inventory questions), and that value increased by 18% after they completed the LT. To determine if the increase resulted from extra time spent on the topic rather than the unique approach of LTs, we also tested how an extended lecture, in lieu of LTs, affected student scores. After an extended lecture, student scores increased by only 5% on multiple-choice questions. Therefore, we conclude that LTs are more effective than lecture alone in increasing student knowledge. LTs have been written to be relatively easy to implement in classrooms without a large time commitment or dramatic course redesign. Thirteen LTs have currently been tested, and more are being developed

  16. Interactive lectures: Clickers or personal devices?

    Morrell, Lesley J.; Joyce, Domino A.

    2015-01-01

    Audience response systems (‘clickers’) are frequently used to promote participation in large lecture classes, and evidence suggests that they convey a number of benefits to students, including improved academic performance and student satisfaction. The limitations of these systems (such as limited access and cost) can be overcome using students’ personal electronic devices, such as mobile phones, tablets and laptops together with text message, web- or app-based polling systems. Using questionnaires, we compare student perceptions of clicker and smartphone based polling systems. We find that students prefer interactive lectures generally, but those that used their own device preferred those lectures over lectures using clickers. However, device users were more likely to report using their devices for other purposes (checking email, social media etc.) when they were available to answer polling questions. These students did not feel that this distracted them from the lecture, instead, concerns over the use of smartphones centred around increased battery usage and inclusivity for students without access to suitable technology. Our results suggest that students generally preferred to use their own devices over clickers, and that this may be a sensible way to overcome some of the limitations associated with clickers, although issues surrounding levels of distraction and the implications for retention and recall of information need further investigation.

  18. On performing concepts during science lectures

    NASA Astrophysics Data System (ADS)

    Pozzer-Ardenghi, Lilian; Roth, Wolff-Michael

    2007-01-01

    When lecturing, teachers make use of both verbal and nonverbal communication. What is called teaching, therefore, involves not only the words and sentences a teacher utters and writes on the board during a lesson, but also all the hands/arms gestures, body movements, and facial expressions a teacher performs in the classroom. All of these communicative modalities constitute resources that are made available to students for making sense of and learning from lectures. Yet in the literature on teaching science, these other means of communication are little investigated and understood - and, correspondingly, they are undertheorized. The purpose of this position paper is to argue for a different view of concepts in lectures: they are performed simultaneously drawing on and producing multiple resources that are different expressions of the same holistic meaning unit. To support our point, we provide examples from a database of 26 lectures in a 12th-grade biology class, where the human body was the main topic of study. We analyze how different types of resources - including verbal and nonverbal discourse and various material artifacts - interact during lectures. We provide evidence for the unified production of these various sense-making resources during teaching to constitute a meaning unit, and we emphasize particularly the use of gestures and body orientations inside this meaning unit. We suggest that proper analyses of meaning units need to take into account not only language and diagrams but also a lecturer's pointing and depicting gestures, body positions, and the relationships between these different modalities. Scientific knowledge (conceptions) exists in the concurrent display of all sense-making resources, which we, following Vygotsky, understand as forming a unit (identity) of nonidentical entities.

  19. Impact of an informed choice invitation on uptake of screening for diabetes in primary care (DICISION): randomised trial

    2010-01-01

    Objective To compare the effect of an invitation promoting informed choice for screening with a standard invitation on attendance and motivation to engage in preventive action. Design Randomised controlled trial. Setting Four English general practices. Participants 1272 people aged 40-69 years, at risk for diabetes, identified from practice registers using a validated risk score and invited to attend for screening. Intervention Intervention was a previously validated invitation to inform the decision to attend screening, presenting diabetes as a serious potential problem, and providing details of possible costs and benefits of screening and treatment in text and pie charts. This was compared with a brief, standard invitation simply describing diabetes as a serious potential problem. Main outcome measures The primary end point was attendance for screening. The secondary outcome measures were intention to make changes to lifestyle and satisfaction with decisions made among attenders. Results The primary end point was analysed for all 1272 participants. 55.8% (353/633) of those in the informed choice group attended for screening, compared with 57.6% (368/639) in the standard invitation group (mean difference −1.8%, 95% confidence interval −7.3% to 3.6%; P=0.51). Attendance was lower among the more deprived group (most deprived third 47.5% v least deprived third 64.3%; P<0.001). Interaction between deprivation and effect of invitation type on attendance was not significant. Among attenders, intention to change behaviour was strong and unaffected by invitation type. Conclusions Providing information to support choice did not adversely affect attendance for screening for diabetes. Those from more socially deprived groups were, however, less likely to attend, regardless of the type of invitation received. Further attention to invitation content alone is unlikely to achieve equity in uptake of preventive services. Trial registration Current Controlled Trials ISRCTN

    The present article describes teaching experiences and observations in college courses and public lectures on twins. It is concluded that much more information about twins, at both research and practical levels, requires general dissemination. This discussion is followed by reviews of recent twin research on the topics of obesity control, post-zygotic mutation, in vitro fertilization, and schisis-associated defects. Media reports of twins accused of rape, infant Chinese twins sold separately for profit, a twin CEO, and twins pursuing the same career are presented.

  1. Intrinsic deficiencies of lectures as a teaching method.

    PubMed

    2013-06-01

    Lectures were, still are and seem to remain a dominant form of teaching, despite an increased research and use of other methods of teaching and leverage of technology aimed at improving teaching results and efficiency. Learning, as the result of a lecture, greatly depends on the subject, the competence and abilities of the lecturer as well as on other transient causes. However, lectures also have some intrinsic deficiencies as a teaching method pertinent to their very nature. In order to fully understand the teaching value of lectures and their role and proper use in educational systems, their deficiencies have been studied in a theoretical analysis from the perspective of cognitive learning theories. Fifteen deficiencies have been identified and clustered in three categories based on root causes of deficiencies: synchronicity problems, time constraint and individual student abilities, needs and knowledge. These findings can be used to adjust expected learning outcomes of lectures, to properly (re)design lecture content and process and to design other learning and teaching activities that would compensate and complement lectures. Recommendations are given on replacing and amending lectures with other instructional methods, amending lectures in the course of delivery with additional content and tools and complementing lectures after delivery with content, tools and activities. Suggestions on the use of information technology that could substitute, reduce or eliminate at least some of the deficiencies are made. Lecture captures seem to be valuable supplement for live lectures compensating in all three categories of deficiencies. Suggestions and directions for further research are given.

    Compared to Ernst Mach's influence on the conceptual development of physics, his efforts to popularize science and his reflections on science literacy are known to a much lesser degree. The approach and the impact of Mach's popular scientific lectures are discussed in view of today's problems of understanding science. The key issues of Mach's popular scientific lectures, reconsidered in the light of contemporary science, still hold a high potential in fascinating a general audience. Moreover, Mach's grand theme, the relation of the physical to the psychical, is suited to contribute to a dialogue between different knowledge cultures, e.g. science and humanities.

    2015-01-01

    Science students can benefit from visual aids. In biology lectures, visual aids are usually limited to tables, figures, and PowerPoint presentations. In this IRB-approved study, we examined the effectiveness of the use of five prop demonstrations, three of which are at the intersection of biology and chemistry, in three community college biology courses. We hypothesized that students’ performance on test questions is enhanced by the use of prop demonstrations. Consistent with our hypothesis, we showed that students learn more effectively and perform better on questions that relate to demonstrations than on questions related to lessons that do not have a demonstration component.

    2012-03-01

    We conducted a randomized controlled study to compare conventional lectures with tele-education for delivering wound care education. Education was delivered by the two methods simultaneously to two classes. Forty-eight paramedics received a live didactic presentation and 41 paramedics received the same lecture via videoconferencing. The participants were evaluated by a multiple-choice examination and a practical test of their wound closure skills. There were no significant differences in any category of the practical skills test, and no difference in the results of the written examination: the mean total score was was 109.0 (95% CI 105.7-112.4) in the conventional lecture group and 110.3 (95% CI 106.2-114.3) in the video group (P = 0.63). In a survey at the end of the study the live lecture group rated the overall effectiveness of teaching significantly higher than the video-based group: the median scores for effectiveness of teaching were 6.0 (IQR 5.5-6.0) in the live lecture group and 4.0 (IQR 3.0-5.0) in the video group (P < 0.001). Videoconferencing was at least as effective as live didactic presentation.

    van de Giesen, Nick

    2015-04-01

    As Lord Kelvin observed: "If you can not measure it, you can not improve it." Measurement is the start of all scientific knowledge. Measurement sets science apart from metaphysical speculation. Measurement is not the last word in science but it is the first. In hydrology, progress in measurement methods has not been as rapid as in sister Earth sciences such as meteorology, oceanography, or geodynamics. Of the hundreds of scientific satellites, only one has hydrology as its main mission at the time of this writing (hopefully two at the time of the lecture). The closest we come to a large measurement infrastructure is an experimental watershed. Nothing wrong with an experimental watershed but it does not compare to, say, the Square Kilometer Array with its exabyte per day output. We tend to give up quickly because we will always have to work with effective parameters that can not be measured directly. We will never be able to know all stomata in a tree and how they interact with the turbulent flow through the canopy. We will never be able to know all pores in a soil and how water moves through them. But also effective parameters have to be measured, be it indirectly. No surprise then that my presentation will focus on measurements in hydrology and water management. First, the fun aspects and intellectual challenges of developing new measurement methods will be highlighted. From weighing trees to listening to rain to taking a stream's temperature, we have had many interesting experiences over the years. Second, the balance between model complexity and data availability will be discussed. Although there is a generally recognized need for parsimonious models in hydrology, formal approaches to finding the correct level of complexity are rare. Some complexity control approaches, borrowed from computer science, will be presented together with a hydrological application. As it turns out, these methods seem to predict nicely the onset of equifinality or the statistical

  3. BOOK REVIEW: Feynman Lectures on Gravitation

    NASA Astrophysics Data System (ADS)

    Feynman, Richard P.; Morinigo, Fernando B.; Wagner, William G.

    2003-05-01

    In the early 1960s Feynman lectured to physics undergraduates and, with the assistance of his colleagues Leighton and Sands, produced the three-volume classic Feynman Lectures in Physics. These lectures were delivered in the mornings. In the afternoons Feynman was giving postgraduate lectures on gravitation. This book is based on notes compiled by two students on that course: Morinigo and Wagner. Their notes were checked and approved by Feynman and were available at Caltech. They have now been edited by Brian Hatfield and made more widely available. The book has a substantial preface by John Preskill and Kip Thorne, and an introduction entitled 'Quantum Gravity' by Brian Hatfield. You should read these before going on to the lectures themselves. Preskill and Thorne identify three categories of potential readers of this book. 1. Those with a postgraduate training in theoretical physics. 2. 'Readers with a solid undergraduate training in physics'. 3. 'Admirers of Feynman who do not have a strong physics background'. The title of the book is perhaps misleading: readers in category 2 who think that this book is an extension of the Feynman Lectures in Physics may be disappointed. It is not: it is a book aimed mainly at those in category 1. If you want to get to grips with gravitation (and general relativity) then you need to read an introductory text first e.g. General Relativity by I R Kenyon (Oxford: Oxford University Press) or A Unified Grand Tour of Theoretical Physics by Ian D Lawrie (Bristol: IoP). But there is no Royal Road. As pointed out in the preface and in the introduction, the book represents Feynman's thinking about gravitation some 40 years ago: the lecture course was part of his attempts to understand the subject himself, and for readers in all three categories it is this that makes the book one of interest: the opportunity to observe how a great physicist attempts to tackle some of the hardest challenges of physics. However, the book was written 40

    , amongst others, the following topics: fundamentals of plasma physics, fusion plasmas, plasmas in astrophysics and space physics, plasma applications and technologies, complex plasmas, high energy density plasmas, quantum plasmas and laser-plasma interaction. A total of 180 delegates from 34 different countries took part in ICPP-LAWPP-2010, and 60 delegates received financial assistance from the Local Organizing Committee, thanks to the support granted by the International Union for Pure and Applied Physics (IUPAP) and by CCHEN. The ICPP-LAWPP-2010 Program was established by the following Program Committee: • Carlos Alejaldre, ITER • Maria Virginia Alves, Brazil • Julio Herrera, Mexico • Günter Mank, IAEA • George Morales, USA • Padma Kant Shukla, Germany • Guido Van Oost, Belgium • Leopoldo Soto, Chile (Chairman) This Program Committee was formed of selected members from the International Advisory Committee of the ICPP and from the International Advisory Committee of the LAWPP (http://www.icpp-lawpp-2010.cl/page/committees.php). In particular, plenary lectures and invited topical lectures were selected by the Program Committee from a list of nominated lectures presented by the International Advisory Committees of both ICPP and LAWPP. Also, the classification of oral and poster presentations was established by the Program Committee. The Congress included 15 invited plenary talks, 33 invited topical talks, 45 oral contributions, and 160 poster contributions. Most of the plenary and topical lectures are published in this special issue of Plasma Physics and Controlled Fusion. The papers were refereed according to the usual standards of the journal. Prior to ICPP-LAWPP 2010, an important activity usually associated with the Latin American Workshop on Plasma Physics took place. This activity was the LAWPP School on Plasma Physics, which was open to participants from all over the world, providing basic training to students and young researchers. The School was

  10. An Inverse MOOC Model: Small Virtual Field Geology Classes with Many Teachers (Invited)

    2013-12-01

    In the Massive Open Online Courses (MOOCs) mode of instruction, one or a small group of collaborating instructors lecture online to a large (often extremely large) number of students. We are experimenting with an inverse concept: an online classroom in which a small group of collaborating students are taught by dozens of collaborating instructors. This experiment is part of a new NSF TUES Type 3 project titled 'Google Earth for Onsite and Distance Education (GEODE).' Among the goals of the project are the development of an online course called the 'Grand Tour.' We are inviting dozens of colleagues to record virtual field trips (VFTs) and upload them to Google Earth. Students enrolled in the course will be assigned to a small group and tasked with a research project--for example to write a report on foreland thrust belts. They will select a small subset of available VFTs to follow and will be scaffolded by virtual specimens, emergent cross sections, analytical simulations (virtual tricorders), and a game style environment. Instant feedback based on auto-logging will enable adaptive learning. The design is suited to both onsite and distance education and will facilitate access to iconic geologic sites around the world to persons with mobility constraints. We invite input from the community to help guide the design phase of this project. Prototypes of the above-listed learning resources have already been developed and are freely available at http://www.DigitalPlanet.org.

    The dishwasher died after faithfully serving the household for over seventeen years. One would expect a MacGyver treasure trove of parts to be found inside. Here, we will present what could be salvaged from a dishwasher that could be of use to hydrological research. The dishwasher's demise was too close to the submission deadline to promise anything in detail but there will be pumps, valves, level sensors, temperature sensors and, perhaps, a turbidity sensor. In addition, there may be more generic parts of interest such as timers, transformers and heaters. What will be presented is a hydrology oriented anatomy lesson of a dishwasher that would make Dr. Nicolaes Tulp proud.

    2005-05-01

    Interactive learning is crucial to the retention of knowledge (especially scientific) and learning in astronomy is no exception. We have developed three classroom activities that cover common astronomy concepts that are difficult to master: Phases of the Moon, Eclipses, and Impacts and Probability. These activities were planned to integrate into an introductory astronomy course for non-majors at Georgia State University. Each activity consists of hands-on models that small groups of students may utilize to complete a conceptual exercise that requires them to make predictions. We envision these three activities as prototypes for lecture activities throughout the introductory astronomy sequence. We report here on the scope of the activities and their effectiveness in the lecture tutorial context. This research has been sponsored by the Georgia Partnership for Reform In Science and Mathematics (PRISM) which is funded by the National Science Foundation.

    2016-05-01

    As English-medium instruction (EMI) spreads around the world, university teachers and students who are non-native speakers of English (NNS) need to put much effort into the delivery or reception of content. Construction of scientific meaning in the process of learning is already complex when instruction is delivered in the first language of the teachers and students, and may become even more challenging in a second language, because science education depends greatly on language. In order to identify important pedagogical functions that teachers use to deliver content and to present different ways to realise each function, a corpus of lectures related to science and engineering courses was created and analysed. NNS teachers and students in science and engineering involved in EMI higher education can obtain insights for delivering and listening to lectures from the Online Corpus of Academic Lectures (OnCAL).

    Feldman, Steven R

    2007-10-13

    The following is adapted from the Clarence S. Livingood Lecture delivered at the 2006 American Academy of Dermatology Annual Meeting. The Livingood Lecture is the only presentation during the Annual Meeting of the American Academy of Dermatology that is specifically dedicated to issues other than the science and practice of dermatology. The lecture describes the impact of the compartmentalization of Medicine. Compartments prevent us from seeing certain things and make some of our own observations untrustworthy. Furthermore, compartments affect the context in which we interpret our observations. These limitations on perception impact the physician-patient relationship and outcomes of care, as well as inter-specialty relationships. Compartments may even play a critical role in world conflicts. We would be wise to follow Dr. Livingood's advice to look beyond the borders in our lives.

    PubMed Central

    Packard, Randall M.

    2016-01-01

    Summary In the Autumn of 1780 an epidemic hit the city of Philadelphia. The symptoms of the disease resembled those of present day dengue fever, and subsequent observers argued that the disease was in fact dengue. But was it? The question forces us to confront the challenges of retrospective epidemiology and how we examine the history of a disease. This paper examines the 1780 epidemic from two perspectives. First, it looks at evidence that the disease was dengue and examines what this tells us about the epidemic and the conditions that caused it. Second, it looks at the disease from the perspective of Dr. Benjamin Rush, who treated hundreds of patients during the epidemic. In other words, it examines the disease through the lens of eighteenth century medical ideas. The paper concludes that each approach is valuable and reveals different aspects of the relationship between society and disease. PMID:27374846

    2006-12-01

    The poster will present a few of low tech and low cost, but highly interactive and fun lecture demonstrations which can be successfully implemented in a small as well as in a large introductory physics courses. The advantage of these mini experiments is that being cheap and easily prepared these demos can become small take home projects which the students can share with their friends and families. One of these demonstrations is a modified reaction time experiment using a ruler cut out of paper and paper clips; the second one uses a small spring, a string and a weight (or a ball on a rubber band) to demonstrate the difference between weight and apparent weight; the third one is a simple modification of a Greek Waiter Demo using paper coffee cups and a string and the last one demonstrates production of sound waves in a tube using bubble tea straws. These small lecture demonstrations can make a big difference and will help every physics instructor make his or her introductory physics classes more meaningful, fun and engaging.

  3. Lecture demonstrations of interference and quantum erasing with single photons

    NASA Astrophysics Data System (ADS)

    Dimitrova, T. L.; Weis, A.

    2009-07-01

    Single-photon interference is a beautiful manifestation of the wave-particle duality of light and the double-slit Gedankenexperiment is a standard lecture example for introducing quantum mechanical reality. Interference arises only if each photon can follow several (classical) paths from the source to the detector, and if one does not have the possibility to determine which specific path the photon has taken. Attaching a specific label to the photon traveling along a specific path destroys the interference. However, in some cases those labels can be erased from the photon between leaving the apparatus and being detected, by which interference can be restored, a phenomenon called quantum erasing. We present lecture demonstration experiments that illustrate the wave-particle duality of light and the phenomenon of quantum erasing. Both experiments are first shown with strong light and, in a second step, on a photon-by-photon basis. The smooth transition from the quantum to the classical case can be shown in real time by varying the incident light intensity.

    2006-02-01

    WebCT, a web-based virtual learning environment (VLE) and Interactive TV (ITV) are relatively new technologies that are used to deliver distance education at the Faculty of Health Sciences, Stellenbosch University. This study explores how effective current approaches to instructional design and interaction have been in utilizing these two technologies to support interaction and what lessons can be learnt. Five focus-group interviews were held with students and lecturers to assess the perceived quality of student-lecturer/student-student interactions. All students were invited to complete a questionnaire at the end of every module to assess their perceptions of interaction. Interaction was highly valued by students and lecturers participating in distance-learning programmes utilizing either VLE or ITV. Students rated courses using both technologies as moderately interactive. Significant differences between VLE and ITV were detected in student-lecturer and student-student interactions, use of additional modes of communication, instructional design, technological interactivity and social rapport activities. The groups did not differ across a number of likely barriers to interaction and both also reported the need for more flexible and better paced instructional designs.

  9. Preventive home visits to older home-dwelling people in Denmark: are invitational procedures of importance?

    PubMed

    Ekmann, A; Vass, M; Avlund, K

    2010-11-01

    Since 1998 all municipalities in Denmark have been required by law to offer two annual preventive home visits to all home-dwelling citizens aged 75 or over. The influence of invitational procedures on acceptance rates has not been investigated. The aim of this study was to describe and investigate whether different invitational procedures were associated with first preventive home visit acceptance rates. The study was based on secondary analyses of data from the Danish Intervention Study on Preventive Home Visits. Data were collected from 1998 to 2002. Of the 4060 participants in the main study, 3245 reported receiving an offer for an identifiable preventive home visit, of whom 2399 (73.9%) provided complete data for the main analyses in the present study. Invitational procedures were categorised as: (1) a letter with a proposed date and time for the visit, (2) a visitor telephone call, and (3) a letter with encouragement to phone the visitor for appointment (letter without a proposed date). Covariates included sex, age, experience with preventive interventions, functional ability, self rated health, social relations and psychosocial characteristics. Statistical analyses included chi-square tests, and bi- and multivariable logistic regression analyses. Different invitational procedures were associated with first preventive home visit acceptance rates. Significantly more men (75.1%) than women (62.8%) declined the first preventive home visit regardless of the invitational procedure. Compared to 'letter with a proposed date', men had an odds ratio of 1.78 (95% CI: 1.16-2.74) for declining visits when 'telephone call' was used and an odds ratio 2.81 (95% CI: 1.79-4.40) when 'letter without a proposed date' was used as the invitational procedure. In women the odds ratios were 1.23 (95% CI: 0.91-1.68) and 1.87 (95% CI: 1.37-2.55), respectively.

    2006-12-01

    This second volume of "Lecture Notes and Essays in Astrophysics" contains a selection of lectures on a variety of topics that contribute to illustrate the current healthy state of Spanish Astrophysics. The first "lecture notes" review two space projects with a relevant participation from the Spanish Astrophysical community, CoRoT and Cassini-Huygens missions. The present-day knowledge about Titan, the solar system object with a physical environment most similar to that at Earth, is carefully revised in a pleasant lecture by Luisa María Lara, Rafael Rodrigo and José Juan López Moreno. The recent success in the launching and operativity of the CoRoT mission increases even more the interest of the review by Rafael Garrido and Hans J. Deeg illustrating the search for exoplanets by the CoRoT satellite. The potential discovery of Earth-like planets around other stars will need, apart from sophisticated technological development, the design of techniques for identifying the most representative parameters of their atmospheres and surfaces. Manuel Vazquez, P. Montañés Rodríguez and E. Pallé, review the main results of observations and simulations looking at our planet with low or null resolution, in other words, considering the Earth as an exoplanet. Our aim is to offer the specialized public, and particularly to graduate and postgraduate astrophysics students, selected comprehensive reviews on hot topics lectured by expert researchers on the subject ("Lecture Notes"). As in the first volume of the series, this issue is complemented by a set of chapters on more specific topics ("Essays").

  13. MHD Dynamo phenomenon in our lab (Petrus Peregrinus Medal Lecture)

    Gailitis, Agris

    2016-04-01

    Celestial objects generate magnetic field very like technical dynamo do. Field induces current in a moving electroconductor. The induced current amplifies magnetic field. At large enough product conductivity time's velocity time's size amplification exceeds losses and situation without magnetic field is impossible. Such scenario is obvious for technical dynamo made from insolated wire but not so for uniform conductor as in celestial bodies. Development of the idea took literally the entire 20th century. Discovery of sunspot magnetic fields at the century rise and laboratory verification at the very fall. At thirties Cowling noticed that geometrically simple shaped (axially symmetrical) field can't sustain itself. Process must be more complex, somehow spatially fragmented. At the middle of century Parker and Steenbeck saw such fragmentation in a turbulent structure of hydrodynamic flow. Shortly after his α-effect approach was made ready Steenbeck invited us to think on molten Na experiments for theory verification. The first idea was to push the Na flow through the hand-blown pipe maze. Similar industrial scale experiment after years and regardless of us was realized in Karlsruhe. Seeking for something cheaper we stopped at Ponomarenko idea - axially symmetric helical flow can't generate axi-simmetric field but it can generate azimuthally structured one. The mathematical model was modified to experimental conditions and numerically optimized. The Dynamo stand was built and it works. Even after optimization Dynamo stand exceeds usual size of hydraulic experiments. 2m3 of molten Na circulate there by means of propeller powered from 200kW motor. When circulation exceeds 0.6 m3/s (at 120°C) seemingly from nowhere appears magnetic field. Twisted field pattern slowly (about 1.5Hz) rotates round flow axis. Up to 0.1T field stay as long as stay circulation and temperature. When sodium is heated up or slowed down the field is slowly dying out. Phenomenon is much richer

    We employ a recently developed convection model constrained by seismic, geodynamic and mineral physics data (Simmons et al., GJI 2009) to explore the impact of time-dependent changes in mantle buoyancy forces on tectonic plate accelerations. This plate-coupled mantle convection model incorporates a viscosity structure that reconciles both glacial isostatic adjustment and global convection-related data sets (Mitrovica & Forte, EPSL 2004) and it successfully reproduces present-day plate velocities, global surface gravity and topography data. This convection model predicts the recent deceleration of several major plates in the Pacific and Indo-Atlantic hemispheres. Independent verification of these predictions is a fundamental test of the plausibility of the buoyancy forces and rheological structure in the convection model. To this end, we consider marine magnetic anomaly and space geodetic constraints on tectonic plate motions to determine a new global map of present-day rates of change of plate velocities. This map shows that several major plates, such as the Pacific, Africa and Nazca plates are presently decelerating and that they contribute to a globally-averaged slowdown in tectonic plate speeds. These joint geologic-geodetic inferences of plate decelerations are consistent with those predicted by our tomography-based convection model.

    PubMed

    Solomon, Patricia J

    2009-10-15

    The spirit and content of the 2007 Armitage Lecture are presented in this paper. To begin, two areas of Peter Armitage's early work are distinguished: his pioneering research on sequential methods intended for use in medical trials and the comparison of survival curves. Their influence on much later work is highlighted, and motivate the proposal of several statistical 'truths' that are presented in the paper. The illustration of these truths demonstrates biology's new morphology and its dominance over statistics in this century. An overview of a recent proteomics ovarian cancer study is given as a warning of what can happen when bioinformatics meets epidemiology badly, in particular, when the study design is poor. A statistical bioinformatics success story is outlined, in which gene profiling is helping to identify novel genes and networks involved in mouse embryonic stem cell development. Some concluding thoughts are given.

  17. Impact of an informed choice invitation on uptake of screening for diabetes in primary care (DICISION): trial protocol

    Background Screening invitations have traditionally been brief, providing information only about population benefits. Presenting information about the limited individual benefits and potential harms of screening to inform choice may reduce attendance, particularly in the more socially deprived. At the same time, amongst those who attend, it might increase motivation to change behavior to reduce risks. This trial assesses the impact on attendance and motivation to change behavior of an invitation that facilitates informed choices about participating in diabetes screening in general practice. Three hypotheses are tested: 1. Attendance at screening for diabetes is lower following an informed choice compared with a standard invitation. 2. There is an interaction between the type of invitation and social deprivation: attendance following an informed choice compared with a standard invitation is lower in those who are more rather than less socially deprived. 3. Amongst those who attend for screening, intentions to change behavior to reduce risks of complications in those subsequently diagnosed with diabetes are stronger following an informed choice invitation compared with a standard invitation. Method/Design 1500 people aged 40–69 years without known diabetes but at high risk are identified from four general practice registers in the east of England. 1200 participants are randomized by households to receive one of two invitations to attend for diabetes screening at their general practices. The intervention invitation is designed to facilitate informed choices, and comprises detailed information and a decision aid. A comparison invitation is based on those currently in use. Screening involves a finger-prick blood glucose test. The primary outcome is attendance for diabetes screening. The secondary outcome is intention to change health related behaviors in those attenders diagnosed with diabetes. A sample size of 1200 ensures 90% power to detect a 10% difference in

    2011-01-01

    At the request of the faculty of the Colorado School of Mines, Golden, Colorado, the authors prepared and presented a lecture series to the students of a graduate level advanced instrumental analysis class. The slides and text presented in this report are a compilation and condensation of this series of lectures. The purpose of this report is to present the slides and notes and to emphasize the thought processes that should be used by a scientist submitting samples for analyses in order to procure analytical data to answer a research question. First and foremost, the analytical data generated can be no better than the samples submitted. The questions to be answered must first be well defined and the appropriate samples collected from the population that will answer the question. The proper methods of analysis, including proper sample preparation and digestion techniques, must then be applied. Care must be taken to achieve the required limits of detection of the critical analytes to yield detectable analyte concentration (above "action" levels) for the majority of the study's samples and to address what portion of those analytes answer the research question-total or partial concentrations. To guarantee a robust analytical result that answers the research question(s), a well-defined quality assurance and quality control (QA/QC) plan must be employed. This QA/QC plan must include the collection and analysis of field and laboratory blanks, sample duplicates, and matrix-matched standard reference materials (SRMs). The proper SRMs may include in-house materials and/or a selection of widely available commercial materials. A discussion of the preparation and applicability of in-house reference materials is also presented. Only when all these analytical issues are sufficiently addressed can the research questions be answered with known certainty.

    Background: Nursing education can maintain its dynamic quality when it moves toward innovation and modern methods of teaching and learning. Therefore, teachers are required to employ up to date methods in their teaching plans. This study evaluated the effects of e-learning, lectures, and role playing on nursing students’ learning, retention, and satisfaction. Methods: Sixty nursing students were selected as an experiment and control groups during two consecutive semesters. The educational content was presented as e-learning and role playing during one semester (experiment group) and as lectures in the next semester (control group). A questionnaire containing three parts was used to assess demographics, learning and satisfaction statuses. The questionnaire also included a final openended question to evaluate the students’ ideas about the whole course. Results: The mean scores of posttest were 16.13 ± 1.37 using role playing, 15.50 ± 1.44 using e-learning and 16.45 ± 1.23 using lectures. The differences between the mean scores of posttest and pretest were 12.84 ± 1.43, 12.56 ± 1.57, and 13.73 ± 1.53 in the mentioned methods, respectively. Lectures resulted in significantly better learning compared to role playing and e-learning. In contrast, retention rates were significantly lower using lectures than using role playing and e-learning. Students’ satisfaction from e-learning was significantly lower than lecturing and role playing. Conclusion: Due to the lower rates of retention following lectures, the teachers are recommended to use student- centered approaches in their lectures. Since students’ satisfaction with e-learning was lower than the other methods, further studies are suggested to explore the problems of e-learning in Iran. PMID:26000257

  1. Making large class basic histology lectures more interactive: The use of draw-along mapping techniques and associated educational activities.

    PubMed

    Kotzé, Sanet Henriët; Mole, Calvin Gerald

    2015-01-01

    At Stellenbosch University, South Africa, basic histology is taught to a combination class of almost 400 first-year medical, physiotherapy, and dietetic students. Many students often find the amount of work in basic histology lectures overwhelming and consequently loose interest. The aim was to determine if a draw-along mapping activity would focus students during large class lectures. After each lecture on three basic histology tissues, a guided draw-along mapping session covering the work from the lecture was introduced in the form of a click-advance PowerPoint presentation which was used to demonstrate the unfolding of an "ideal" map. The lecturer simultaneously drew a similar map using an overhead projector allowing the students to draw their own maps on blank sheets of paper along with the lecturer. Students remained attentive during the activity and many participated in answering informal questions posed by the lecturer as the map-making session progressed. After the last session, students completed an anonymous, voluntary questionnaire (response rate of 78%). The majority of students found the draw-along maps useful (94%) and believed that its use should be continued in the future (93%). A significant increase (P < 0.001) was found in the test results of student cohorts who were given the current intervention compared to cohorts from previous years who were given mind maps as handouts only or had no intervention. The use of the draw-along mapping sessions were successful in focusing students during large class lectures while also providing them with a useful tool for their studies.

  4. The Problem Life Solves (Invited)

    Shock, E.

    2013-12-01

    After forming, planets start the long process of dissipating energy into space. Early on, accretionary processes provide sufficient kinetic energy to raise temperatures enough to drive chemical systems rapidly toward equilibrium, maximizing the release of chemical energy. Eventually heat is dissipated, temperatures drop, and outer portions of planets cool enough to slow the rates of chemical reactions. As reaction rates slow to the scale of geologic time, chemical energy becomes trapped in assemblages of planetary materials far from equilibrium. Numerous examples are provided by chondritic meteorites, which show that activation energy barriers allow chemical energy to remain trapped for most of the age of the solar system even if heat dissipation is efficient -- and perhaps as a direct consequence. Activation energies that inhibit favorable reactions can be overcome by catalysis, which permits chemical systems to attain lower energy states. Catalysis in planets serves to continue the release of energy into space begun by heat dissipation. This implies that there is an overall thermodynamic drive for catalysis to appear as planets cool. Reasons why catalysis emerges in some cases and not others may depend on interactions of cooling rates and compositions but the specifics are murky at present. Life is a particularly efficient catalyst, and its emergence on a planet helps solve the problem generated by the catastrophic decrease in reaction rates during cooling. The single example we have of life on Earth got its start catalyzing oxidation-reduction reactions arranged in states far from equilibrium by geologic processes. On the pre-photosynthetic Earth the boldest biosignatures were redox processes occurring at rates that could only be explained by catalysis, and specifically by catalytic processes that have no abiotic mechanism. Biologically enhanced rates of redox reactions persist to the present, and maintain the biogeochemical cycles that permit the photosynthetic

    The objective of this review is to present an overview of some of the most commonly consumed artisanal Mexican cheeses, as well as those cheeses that show potential for a protected designation of origin. A description is given for each of these cheeses, including information on their distinguishing characteristics that makes some of them potential candidates for achieving a protected designation of origin status. This distinction could help to expand their frontiers and allow them to become better known and appreciated in other parts of the world. Due to the scarcity of scientific studies concerning artisanal Mexican cheeses, which would ultimately aid in the standardization of manufacturing processes and in the establishment of regulations related to their production, more than 40 varieties of artisanal cheese are in danger of disappearing. To preserve these cheeses, it is necessary to address this challenge by working jointly with government, artisanal cheesemaking organizations, industry, academics, and commercial partners on the implementation of strategies to protect and preserve their artisanal means of production. With sufficient information, official Mexican regulations could be established that would encompass and regulate the manufacture of Mexican artisanal cheeses. Finally, as many Mexican artisanal cheeses are produced from raw milk, more scientific studies are required to show the role of the lactic acid bacteria and their antagonistic effect on pathogenic microorganisms during aging following cheese making.

  6. Solar Cycle Predictions (Invited Review)

    Pesnell, W. Dean

    2012-11-01

    Solar cycle predictions are needed to plan long-term space missions, just as weather predictions are needed to plan the launch. Fleets of satellites circle the Earth collecting many types of science data, protecting astronauts, and relaying information. All of these satellites are sensitive at some level to solar cycle effects. Predictions of drag on low-Earth orbit spacecraft are one of the most important. Launching a satellite with less propellant can mean a higher orbit, but unanticipated solar activity and increased drag can make that a Pyrrhic victory as the reduced propellant load is consumed more rapidly. Energetic events at the Sun can produce crippling radiation storms that endanger all assets in space. Solar cycle predictions also anticipate the shortwave emissions that cause degradation of solar panels. Testing solar dynamo theories by quantitative predictions of what will happen in 5 - 20 years is the next arena for solar cycle predictions. A summary and analysis of 75 predictions of the amplitude of the upcoming Solar Cycle 24 is presented. The current state of solar cycle predictions and some anticipations of how those predictions could be made more accurate in the future are discussed.

  7. Introductory lecture: basic quantities in model biomembranes.

    PubMed

    Nagle, John F

    2013-01-01

    One of the many aspects of membrane biophysics dealt with in this Faraday Discussion regards the material moduli that describe energies at a supramolecular level. This introductory lecture first critically reviews differences in reported numerical values of the bending modulus K(C), which is a central property for the biologically important flexibility of membranes. It is speculated that there may be a reason that the shape analysis method tends to give larger values of K(C) than the micromechanical manipulation method or the more recent X-ray method that agree very well with each other. Another theme of membrane biophysics is the use of simulations to provide exquisite detail of structures and processes. This lecture critically reviews the application of atomic level simulations to the quantitative structure of simple single component lipid bilayers and diagnostics are introduced to evaluate simulations. Another theme of this Faraday Discussion was lateral heterogeneity in biomembranes with many different lipids. Coarse grained simulations and analytical theories promise to synergistically enhance experimental studies when their interaction parameters are tuned to agree with experimental data, such as the slopes of experimental tie lines in ternary phase diagrams. Finally, attention is called to contributions that add relevant biological molecules to bilayers and to contributions that study the exciting shape changes and different non-bilayer structures with different lipids.

  8. Silica Lubrication in Faults (Invited)

    Silica-rich rocks are common in the crust, so silica lubrication may be important for causing fault weakening during earthquakes if the phenomenon occurs in nature. In laboratory friction experiments on chert, dramatic shear weakening has been attributed to amorphization and attraction of water from atmospheric humidity to form a 'silica gel'. Few observations of the slip surfaces have been reported, and the details of weakening mechanism(s) remain enigmatic. Therefore, no criteria exist on which to make comparisons of experimental materials to natural faults. We performed a series of friction experiments, characterized the materials formed on the sliding surface, and compared these to a geological fault in the same rock type. Experiments were performed in the presence of room humidity at 2.5 MPa normal stress with 3 and 30 m total displacement for a variety of slip rates (10-4 - 10-1 m/s). The friction coefficient (μ) reduced from >0.6 to ~0.2 at 10-1 m/s, but only fell to ~0.4 at 10-2 - 10-4 m/s. The slip surfaces and wear material were observed using laser confocal Raman microscopy, electron microprobe, X-ray diffraction, and transmission electron microscopy. Experiments at 10-1 m/s formed wear material consisting of ≤1 μm powder that is aggregated into irregular 5-20 μm clumps. Some material disaggregated during analysis with electron beams and lasers, suggesting hydrous and unstable components. Compressed powder forms smooth pavements on the surface in which grains are not visible (if present, they are <100 nm). Powder contains amorphous material and as yet unidentified crystalline and non-crystalline forms of silica (not quartz), while the worn chert surface underneath shows Raman spectra consistent with a mixture of quartz and amorphous material. If silica amorphization facilitates shear weakening in natural faults, similar wear materials should be formed, and we may be able to identify them through microstructural studies. However, the sub

    At Michigan State University, we have used two Education/Public Outreach (EPO) grants, from the Great Observatories Hubble and Chandra, to involve individual researchers in the development of simulations and software to be used in the "ASTRO-101" classroom. I will discuss the products we developed for these projects. One is a laboratory exercise using what we developed to call "DS9-Lite" to allow the students to measure angles and distances on HST images. We embedded a full-featured DS9 (FITS image viewer) in a Flash framework, but display with far fewer buttons and features to distract the student. For the 2nd project, we developed some animations in collaboration with the SAO Media Lab to explain the rationale for dark matter in the universe. These animations can be used in a powerpoint lecture presentation (slides provided) to spark classroom discussion about dark matter. We also discuss the challenge of developing and evaluating these projects, and lessons learned.

  11. The Color Glass Condensate and the Glasma: Two Lectures.

    SciTech Connect

    McLerran,L.

    2007-08-29

    These two lectures concern the Color Glass Condensate and the Glasma. These are forms of matter which might be studied in high energy hadronic collisions. The Color Glass Condensate is high energy density gluonic matter. It constitutes the part of a hadron wave function important for high energy processes. The Glasma is matter produced from the Color Glass Condensate in the first instants after a collision of two high energy hadrons. Both types of matter are associated with coherent fields. The Color Glass Condensate is static and related to a hadron wavefunction, where the Glasma is transient and evolves quickly after a collision. I present the properties of such matter, and some aspects of what is known of their properties.

    successfully. The attraction of using the CCD, even to look at a small portion of the Laue pattern, is to view the diffraction in real time. This will allow tight control of parasitic scatter for microcrystal Laue diffraction and real-time monitoring for time-resolved work. We performed initial experiments using a direct detection CCD imager, and have obtained satisfactory diffraction data on a 40 ms time scale. Results of this work will be presented. In order to assess the efficacy of the Laue method for quantitative crystallography, we have used Laue data from the protein pea lectin and compared it in detail with monochromatic pea lectin data. To assess the use of a vertically focussing mirror, we have successfully used a mercury derivative protein crystal to yield isomorphous and anomalous differences suitable for phase determination. In both the pea lectin and mercury derivative cases, doublet Laue spots were deconvoluted. In the latter case, the data were used in a difference Fourier calculation which showed the mercury peak. Future developments and projections based on multipole sources are given.

  14. Localization of α-adrenoceptors: JR Vane Medal Lecture

    McGrath, John C

    2015-01-01

    This review is based on the JR Vane Medal Lecture presented at the BPS Winter Meeting in December 2011 by J.C. McGrath. A recording of the lecture is included as supporting information. It covers his laboratory's work from 1990 to 2010 on the localization of vascular α1-adrenoceptors in native tissues, mainly arteries. Main points: (i) α1-adrenoceptors are present on several cell types in arteries, not only on medial smooth muscle, but also on adventitial, endothelial and nerve cells; (ii) all three receptor subtypes (α1A, α1B, α1D) are capable of binding ligands at the cell surface, strongly indicating that they are capable of function and not merely expressed. (iii) all of these cell types can take up an antagonist ligand into the intracellular compartments to which endocytosing receptors move; (iv) each individual subtype can exist at the cell surface and intracellularly in the absence of the other subtypes. As functional pharmacological experiments show variations in the involvement of the different subtypes in contractions of different arteries, it is concluded that the presence and disposition of α1-adrenoceptors in arteries is not a simple guide to their involvement in function. Similar locations of the subtypes, even in different cell types, suggest that differences between the distribution of subtypes in model systems do not directly correlate with those in native tissues. This review includes a historical summary of the alternative terms used for adrenoceptors (adrenergic receptors, adrenoreceptors) and the author's views on the use of colours to illustrate different items, given his partial colour-blindness.

    2006-01-01

    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. PMID:16602385

    PubMed

    Maunye, T J; Meyer, S M; van Velden, C E

    2009-09-01

    The need for the utilization of various teaching strategies by lecturers when facilitating learning cannot be overemphasized. The aim of this study was to establish if lecturers at a Nursing College in Mpumalanga were using teaching strategies that could facilitate the personal development of nursing learners. A quantitative approach was followed for this study. The participants of the study were all lecturers at a Nursing College in Mpumalanga. Data was gathered by means of a questionnaire. Descriptive statistics were used to describe and summarize data regarding the type of teaching strategies used and the recommendations that could enhance the utilization of various teaching strategies. The data revealed that the teaching strategies mostly utilized required active participation of the learners namely:formal/informal writing of assignments; learner-led class presentation; group sessions; clinical case studies; role-playing and clinical rounds. Inclusion of certain strategies such as problem-based learning, structured accompaniment and computer literacy for learners could enhance the personal development of nursing learners. Although lecturers did use some of the teaching strategies that could enhance the personal development of nursing learners, staff development regarding the utilization of various teaching strategies was highlighted as an important factor to be considered. Other findings revealed that lack of resources have a negative influence on the utilization of various teaching strategies.

  8. Using theatre in education in a traditional lecture oriented medical curriculum

    PubMed Central

    2009-01-01

    Background Lectures supported by theatrical performance may enhance learning and be an attractive alternative to traditional lectures. This study describes our experience with using theatre in education for medical students since 2001. Methods The volunteer students, coached by experienced students, were given a two-week preparation period to write and prepare different dramatized headache scenarios during three supervised meetings. A theatrical performance was followed by a student presentation about history taking and clinical findings in diagnosing headache. Finally, a group discussion led by students dealt with issues raised in the performance. The evaluation of the theatre in education lecture "A Primary Care Approach to Headache" was based on feedback from students. Results More than 90% of 43 responding students fully agreed with the statement "Theatrical performance made it easier to understand the topic". More than 90% disagreed with the statements "Lecture halls were not appropriate for this kind of interaction" and "Students as teachers were not appropriate". Open-ended questions showed that the lesson was thought of as fun, good and useful by most students. The headache questions in the final exam showed results that were similar to average exam results for other questions. Conclusion Using theatrical performance in medical education was appreciated by most students and may facilitate learning and enhance empathy and team work communication skills. PMID:20003493

  9. Supporting Interactive Teaching Methods at the New Faculty Workshop with Astronomy Lecture-Tutorials

    Slater, T. F.; Brissenden, G.; Duestua, S.; Prather, E. E.

    2004-05-01

    Ongoing research by the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona Steward Observatory suggests that, although faculty realize that lecture-based instruction is ineffective for many students, they are not aware of what interactive teaching strategies are available, particularly for large enrollment courses. A major emphasis of the AAPT/AAS New Faculty Workshop was to introduce faculty to effective active-learning strategies based on an understanding of how people learn. Faculty were introduced to think-pair-share methods where students work together to explain difficult concepts to each other. Faculty were also introduced to authentic assessment strategies that go beyond using traditional multiple-choice tests. In particular, faculty were introduced to Lecture-Tutorials for Introductory Astronomy. The Lecture-Tutorials are instructional materials intended for use with collaborative student learning groups and are designed specifically to be easily integrated into existing courses centered on conventional lectures and do not require any outside equipment or a drastic course revision for implementation. The materials are based on research into student beliefs and reasoning difficulties and use effective instructional strategies that center on student learning. Each workshop presentation was complimented by a follow-up small group discussion session.

  10. Boundary spanning and health: invitation to a learning community.

    Boundaries, which are essential for the healthy functioning of individuals and organisations, can become problematic when they limit creative thought and action. In this article, we present a framework for promoting health across boundaries and summarise preliminary insights from experience, conversations and reflection on how the process of boundary spanning may affect health. Boundary spanning requires specific individual qualities and skills. It can be facilitated or thwarted by organisational context. Boundary spanning often involves risk, but may reap abundant rewards. Boundary spanning is necessary to optimise health and health care. Exploring the process, the landscape and resources that enable boundary spanning may yield new opportunities for advancing health. We invite boundary spanners to join in a learning community to advance understanding and health.

    In these lectures I review the standard hot big-bang cosmology, emphasizing its successes, its shortcomings, and its major challenge-a detailed understanding of the formation of structure in the Universe. I then discuss the motivations for and the fundamentals of inflationary cosmology, particularly emphasizing the quantum origin of metric (density and gravity-wave) perturbations. Inflation addresses the shortcomings of the standard cosmology and provides the initial data'' for structure formation. I conclude by addressing the implications of inflation for structure formation, evaluating the various cold dark matter models in the light of the recent detection of temperature anisotropies in the cosmic background radiation by COBE. In the near term, the study of structure formation offers a powerful probe of inflation, as well as specific inflationary models.

    2015-04-01

    Over the last year significant progress was made in the understanding of the computation of Feynman integrals using differential equations (DE). These lectures give a review of these developments, while not assuming any prior knowledge of the subject. After an introduction to DE for Feynman integrals, we point out how they can be simplified using algorithms available in the mathematical literature. We discuss how this is related to a recent conjecture for a canonical form of the equations. We also discuss a complementary approach that is based on properties of the space-time loop integrands, and explain how the ideas of leading singularities and d-log representations can be used to find an optimal basis for the DE. Finally, as an application of these ideas we show how single-scale integrals can be bootstrapped using the Drinfeld associator of a DE.

    2006-02-01

    We have implemented several research-based transformations in our introductory calculus-based physics course at CU Boulder. These include Peer Instruction with student response system in lecture, Tutorials with trained undergraduate learning assistants in recitations, and personalized computer assignments. In an effort to distinguish the effects of instructor, TA preparation, and particular research-based activities, we present extensive new measurements from six courses representing a spectrum of reforms. This study includes data from Physics I with and without Tutorials, and Physics II with Tutorials. We present multiple quantitative and qualitative measures of success, including validated pre/post content- and attitude-surveys and common exam questions. We investigate the hand-off of reforms between faculty implementing different suites of activities, and begin to assess elements and requirements for success with these transformations. We present evidence that combining research-based interactive engagement methods in lecture, Tutorials, and homework plays a significant positive role in conceptual and attitudinal development.

  1. A retrospective look at replacing face-to-face embryology instruction with online lectures in a human anatomy course.

    PubMed

    Beale, Elmus G; Tarwater, Patrick M; Lee, Vaughan H

    2014-01-01

    Embryology is integrated into the Clinically Oriented Anatomy course at the Texas Tech University Health Sciences Center School of Medicine. Before 2008, the same instructor presented embryology in 13 face-to-face lectures distributed by organ systems throughout the course. For the 2008 and 2009 offerings of the course, a hybrid embryology instruction model with four face-to-face classes that supplemented online recorded lectures was used. One instructor delivered the lectures face-to-face in 2007 and by online videos in 2008-2009, while a second instructor provided the supplemental face-to-face classes in 2008-2009. The same embryology learning objectives and selected examination questions were used for each of the three years. This allowed direct comparison of learning outcomes, as measured by examination performance, for students receiving only face-to-face embryology instruction versus the hybrid approach. Comparison of the face-to-face lectures to the hybrid approach showed no difference in overall class performance on embryology questions that were used all three years. Moreover, there was no differential effect of the delivery method on the examination scores for bottom quartile students. Students completed an end-of-course survey to assess their opinions. They rated the two forms of delivery similarly on a six-point Likert scale and reported that face-to-face lectures have the advantage of allowing them to interact with the instructor, whereas online lectures could be paused, replayed, and viewed at any time. These experiences suggest the need for well-designed prospective studies to determine whether online lectures can be used to enhance the efficacy of embryology instruction.

  8. Are there guidelines for reporting clinical research findings in oral lectures and seminars in dental meetings?

    PubMed

    Faggion, C M

    2013-03-01

    Dental meetings are one of the most important resources for disseminating knowledge to dental practitioners. Therefore, the information provided in such meetings should be as unbiased as possible. This paper assessed whether major general dentistry and periodontology/implant dentistry meetings have guidelines for reporting scientific evidence in oral lectures and seminars. The homepages of seven dental meetings (EUROPERIO, AAP, EAO, AO, IADR, ADA, and FDI) were assessed to check for guidelines for presenting scientific data in oral lectures and seminars, according to defined criteria. Only three of these dental meetings reported information for presentations on their homepages, although these guidelines were related to technical issues rather than recommendations for the presentation of scientific data. The present paper suggests guidelines for reporting scientific evidence in oral lectures and seminars in dental meetings to improve the current standards of reporting. High standards of reporting may provide less biased information, which is necessary for dental practitioners and clinicians to make accurate judgements on the efficacy/effectiveness of therapies.

    Electromyography is a complex diagnostic test that is useful in diagnosing many neuromuscular and musculoskeletal conditions. Physiatrists and neurologists become familiar with this test during their training, while other physicians have minimal or no exposure, outside of perhaps some basic physiology lectures. A review of the anatomy, physiology, and physics upon which electrodiagnostic testing is based and of the various techniques used during a study provides the necessary foundation for understanding and using study results. A discussion of the conditions for which electrodiagnostic testing is useful, including carpal tunnel syndrome, radiculopathy, peripheral neuropathy, and disorders of the neuromuscular junction, is included both to review these disorders and to encourage appropriate referral for electrodiagnostic study.

    In a 2-year project, we developed and trialled a mode of lecturing professional development amongst staff in our department of mathematics. Theoretically grounded in Schoenfeld's resources, orientations, and goals (ROG) model of teacher action, a group met regularly to discuss both the video excerpts of themselves lecturing along with written pre- and post-lecture statements of their "ROGs". We found evidence of improved teaching performance but more interestingly, identified key aspects of our practice and of undergraduate mathematics that received repeated attention and developed further theoretical insight into lecturer behaviour in mathematics. The trial has been successful enough to be expanded into further groups that now constitute a professional development culture within our department.

    NASA Astrophysics Data System (ADS)

    Herrick, Brad Jay

    Students continue to arrive at universities with poor study and time management skills: they are not proactive in their studies while professors are not willing to hold them accountable for their shortcomings. The result is a 'dumbing down' of the course. This can be defeated by student preparation prior to attending lecture, especially in very large-lecture classrooms (N>400). In fact, it provides a process to 'dumb up' the course. A Web-based system for providing content specific lecture preparations (termed 'Previews') was developed and tested in three courses in a large southwestern research institution. Significance was found in final course achievement by treatment levels, including variations by the total number of participations in the lecture preparations. Method of implementation and results are discussed, including future considerations.

    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.

  11. Use and future of wiki systems in veterinary education? – A survey of lecturers in German-speaking countries

    PubMed Central

    Kolski, Darius; Heuwieser, Wolfgang; Arlt, Sebastian

    2015-01-01

    Objectives: Wiki systems are becoming increasingly important in university teaching. Not much is known about the opinion of lecturers of veterinary medicine regarding the active participation of students in teaching, their opinion on wiki systems and their motivation to use them in courses and to improve the quality of information. The objective of the present study was to evaluate how lecturers of veterinary medicine estimate learning management systems and the production of text or material by students in courses, if they rate wiki systems as an appropriate tool for teaching, if they would use wiki systems for their courses and if they are willing to improve the quality of information. Methods: The data collection was carried out as an online survey using a five-point Likert scale. Lecturers of veterinary medicine in Germany, Austria and Switzerland were contacted (n=approx. 1700) out of which 139 completed (8.2%) the survey. Results: Most lecturers use LMS and consider it to be suitable for providing course material. Half of all respondents indicated that they believe that students achieve greater learning success by developing their own learning material. In courses 23.0% of their students develop own materials. The majority of lecturers considered wiki systems as an appropriate and complementary tool for teaching (53.6%). A collection of wiki articles is seen as useful (56.6%), particularly when experts review the contents. One third of the lecturers would use wiki systems for the creation of material by students, but 82.5% have not yet used them in teaching. One third is willing to participate in the review of articles with regard to their quality. Conclusion: The results show that many lecturers are willing to use veterinary wiki systems and that they regard them useful for teaching. According to the opinion of the majority of lecturers, the creation of material by students can lead to greater learning success and wiki systems are suitable for this purpose

    2011-09-01

    Nowadays medical teachers use different audiovisual (AV) aids of teaching in their classes to make the subject more interesting and understandable. To assess the impact of three common lecture delivery methods, viz Blackboard (BB), Transparency and Over Head Projector (OHP) and Powerpoint Presentation (PP), a questionnaire based study was carried out among first year MBBS students of R.G.Kar Medical College, Kolkata. One hundred fouty students of academic session 2010-2011 were exposed to different aids of teaching, viz. Black Board (BB), Over Head Projector (OHP), power point presentation (PP) for ten months. They were taught Anatomy by different teachers who used all the three AV aids in their lectures. Then they were asked to respond to a questionnaire regarding these three AV aids of teaching. The students preferred Black Board teaching over OHP and result was statistically significant (p value < 0.0001). BB teaching was also preferred over PP presentations (p < 0.02). But in comparison to OHP, students preferred PP though the difference is not statistically significant (p < 0.10). Most of the students still prefer Black Board teaching to other modern AV aids like OHP and PP. For better understanding of a subject by students and improvement of their performance, a teacher should match the lectures with preferred AV aids and use the AV aids prudently.

  13. Low Cost Hands-On Activities in Large Lecture Conceptual Physics Course

    The student diversity in a university conceptual physic course presents a challenge to sustain the interest of all the students, to provide a solid conceptual basis for students continuing in science or engineering and to present science as an active subject rather than as vocabulary lists, rules and book knowledge. Combining ideas from the literature for teaching large lecture calculus based physics and science leary education majors in small class settings has resulted in a large (120 student) class format that mixes low cost (< $1,000 for term) hands-on activities, demonstrations, summary discussions and lectures. Hands-on activities are done in small groups which allows the diversity to become an asset. Several of these activities will be described in detail. The effectiveness of this teaching approach will be presented based on results of pre and post Force Concept Inventory test scores for this class and a comparison class that just used lecture and demonstrations for mechanics. The classes under comparison were taught by the same instructor, from the same book, were of similar size and neither had any additional teaching staff.

    Purpose: To describe the use of online seminars (webinars) to improve learning experience for medical residents and fostering critical thinking. Materials and Methods: Sixty-one online seminars (webinars) for residents were developed from April 2012 to February 2013. Residents attended the lectures in the same room as the presenter or from distant locations. Residents interacted with the presenter using their personal computers, tablets, or smartphones. They were able to ask questions and answer the instructor's multiple choice or open-ended questions. The lecture dynamics consisted of: (1) The presentation of a clinical case by an expert on the clinical topic; (2) the instructor asked open-ended and multiple-choice questions about the problem-resolution process; (3) participants responded questions individually; (4) participants received feedback on their answers; (5) a brief conference was given on the learning objectives and the content, also fostering interactive participation; (6) lectures were complemented with work documents. Results: This method allowed for exploration of learning of scientific knowledge and the acquisition of other medical competences (such as patient care, interpersonal and communication skills, and professionalism). The question-and-answer activity and immediate feedback gave attendees the chance to participate actively in the conference, reflect on the topic, correct conceptual errors, and exercise critical thinking. All these factors are necessary for learning. Conclusions: This modality, which facilitates interaction, active participation, and immediate feedback, could allow learners to acquire knowledge more effectively. PMID:24791102

  15. Lectures on probability and statistics. Revision

    Yost, G.P.

    1985-06-01

    These notes are based on a set of statistics lectures delivered at Imperial College to the first-year postgraduate students in High Energy Physics. They are designed for the professional experimental scientist. They begin with the fundamentals of probability theory, in which one makes statements about the set of possible outcomes of an experiment, based upon a complete a priori understanding of the experiment. For example, in a roll of a set of (fair) dice, one understands a priori that any given side of each die is equally likely to turn up. From that, we can calculate the probabilty of any specified outcome. They finish with the inverse problem, statistics. Here, one begins with a set of actual data (e.g., the outcomes of a number of rolls of the dice), and attempts to make inferences about the state of nature which gave those data (e.g., the likelihood of seeing any given side of any given die turn up). This is a much more difficult problem, of course, and one's solutions often turn out to be unsatisfactory in one respect or another. Hopefully, the reader will come away from these notes with a feel for some of the problems and uncertainties involved. Although there are standard approaches, most of the time there is no cut and dried ''best'' solution - ''best'' according to every criterion.

  16. Reconsidering the lecture in modern veterinary education.

    Those teaching in the higher-education environment are now increasingly meeting with larger cohorts of students. The result is additional pressure on the resources available and on the teacher and learners. Against this backdrop, discussions and reflections took place between a practitioner, within a UK veterinary school, and an educational researcher with extensive experience in observing teaching in veterinary medicine. The result was an examination of the lecture as a method of teaching to consider how to resolve identified challenges. The focus of much of the literature is on technical aspects of teaching and learning, reverting to a range of tips to resolve particular issues recognized in large-group settings. We suggest that while these tips are useful, they will only take a practitioner so far. To be able to make a genuine connection to learners and help them connect directly to the discipline, we need to take account of the emotional aspects of our role as teachers, without which, delivery of knowledge may be undermined.

  17. Effect of lecture instruction on student performance on qualitative questions

    Heron, Paula R. L.

    2015-06-01

    The impact of lecture instruction on student conceptual understanding in physics has been the subject of research for several decades. Most studies have reported disappointingly small improvements in student performance on conceptual questions despite direct instruction on the relevant topics. These results have spurred a number of attempts to improve learning in physics courses through new curricula and instructional techniques. This paper contributes to the research base through a retrospective analysis of 20 randomly selected qualitative questions on topics in kinematics, dynamics, electrostatics, waves, and physical optics that have been given in introductory calculus-based physics at the University of Washington over a period of 15 years. In some classes, questions were administered after relevant lecture instruction had been completed; in others, it had yet to begin. Simple statistical tests indicate that the average performance of the "after lecture" classes was significantly better than that of the "before lecture" classes for 11 questions, significantly worse for two questions, and indistinguishable for the remaining seven. However, the classes had not been randomly assigned to be tested before or after lecture instruction. Multiple linear regression was therefore conducted with variables (such as class size) that could plausibly lead to systematic differences in performance and thus obscure (or artificially enhance) the effect of lecture instruction. The regression models support the results of the simple tests for all but four questions. In those cases, the effect of lecture instruction was reduced to a nonsignificant level, or increased to a significant, negative level when other variables were considered. Thus the results provide robust evidence that instruction in lecture can increase student ability to give correct answers to conceptual questions but does not necessarily do so; in some cases it can even lead to a decrease.

    The depth and breadth of pathophysiology content, foundational for nursing practice, is well suited for traditional lecture delivery. Use of creative strategies can deepen students' understanding while respecting students' diverse talents and ways of learning. The authors discuss strategies they used, including case studies, questions asked during lecture using immediate feedback technology, creative visual demonstrations, group pathophysiologic theory projects, short videos, and games, to enhance students' understanding and retention of content.

  19. It's not the done thing: social norms governing students' passive behaviour in undergraduate mathematics lectures

    2011-12-01

    Students often play a passive role in large-scale lectures in undergraduate mathematics courses: they observe the lecturer demonstrate mathematical procedures, but they rarely engage in authentic mathematical activity themselves. This study uses semi-structured interviews of undergraduate students to investigate the implicit and explicit social norms and expectations that influence students to maintain their passive roles during lectures. Students were aware that their passivity was influenced by social norms, but perceived these norms as necessary for allowing the lecturer to get through the content in the allotted lecture time, while enabling students to avoid being publicly embarrassed in the lecture. However, the students appreciated opportunities to work on examples in small groups during lectures. We argue that the success of small group interactions during large-scale lectures depends on students and lecturers establishing supportive social norms, and adjusting their lecture goals from 'covering the content' to 'developing mathematical understanding'.

    The EANM Congress 2014 took place in Gothenburg, Sweden, from 18 to 22 October under the presidency of Prof. Wim Oyen, chair of the EANM Scientific Committee. Prof. Peter Gjertsson chaired the Local Organizing Committee, according to the standardized EANM congress structure. The meeting was a highlight for the multidisciplinary community that forms the heart and soul of nuclear medicine; attendance was exceptionally high. In total almost 5,300 participants came to Gothenburg, and 1,397 colleagues participated via the EANM LIVE sessions ( http://eanmlive.eanm.org/index.php ). Participants from all continents were presented with an excellent programme consisting of symposia, scientific and featured sessions, CME sessions, and plenary lectures. These lectures were devoted to nuclear medicine therapy, hybrid imaging and molecular life sciences. Two tracks were included in the main programme, clustering multi-committee involvement: the 5th International Symposium on Targeted Radionuclide-therapy and Dosimetry (ISTARD) and the first Molecules to Man (M2M) track, an initiative of the EANM Committees for Translational Molecular Imaging, Radiopharmacy and Drug Development. The industry made a substantial contribution to the success of the congress demonstrating the latest technology and innovations in the field. During the closing Highlights Lecture, a selection of the best-rated abstracts was presented including diverse areas of nuclear medicine: physics and instrumentation, radiopharmacy, preclinical imaging, oncology (with a focus on the clinical application of newly developed tracers) and radionuclide therapy, cardiology and neurosciences. This Highlights Lecture could only be a brief summary of the large amount of data presented and discussed during the meeting, which can be found in much greater detail in the congress proceedings book, published as Volume 41, Supplement 2 of the European Journal of Nuclear Medicine and Molecular Imaging in October 2014.

  1. Presentation video retrieval using automatically recovered slide and spoken text

    Video is becoming a prevalent medium for e-learning. Lecture videos contain text information in both the presentation slides and lecturer's speech. This paper examines the relative utility of automatically recovered text from these sources for lecture video retrieval. To extract the visual information, we automatically detect slides within the videos and apply optical character recognition to obtain their text. Automatic speech recognition is used similarly to extract spoken text from the recorded audio. We perform controlled experiments with manually created ground truth for both the slide and spoken text from more than 60 hours of lecture video. We compare the automatically extracted slide and spoken text in terms of accuracy relative to ground truth, overlap with one another, and utility for video retrieval. Results reveal that automatically recovered slide text and spoken text contain different content with varying error profiles. Experiments demonstrate that automatically extracted slide text enables higher precision video retrieval than automatically recovered spoken text.

    We conducted team-based learning (TBL) with interdisciplinary lectures as a part of "Introduction to Pharmacy", divided among the pharmacy department's six pharmacist education curricula in the first semester. The interdisciplinary lecture is led by seven lecturers, each specializing in one area: cell biology, biochemistry, chemistry, public health pharmacology, pharmacokinetics, and clinical science. This lecture's purpose is to demonstrate to the students that all field subjects relate to each other and they must learn the basic science subjects to understand pharmaceutical sciences. The TBL contents have two themes, "cancer" and "aspirin", each of which had two lectures, each 90 minutes long and were conducted using TBL as expansive learning. On receiving knowledge of a wide range of fields in one lecture, a small number of students indicated that they were unable to understand the contents very well. However, in the questionnaire about TBL, many students reported "I have understood" and "I have enjoyed studying" using TBL, especially group readiness assessment test (GRAT). By incorporating TBL, they reported "increasing eagerness to learn pharmacy". Overall, students seem to have accepted TBL favorably, but they still find peer review difficult. We believe that their discomfort with peer review results from their unfamiliarity in evaluating others, and the time before the evaluation is short because TBL is conducted only twice.

    The author, who has had previous experience as a nurse researcher, has been engaged in helping nurse lecturers to undertake evaluation research studies into innovations in their teaching, learning and assessment methods. In order to undertake this work successfully, it was important to move from thinking like a nurse researcher to thinking like an educational researcher and developing the role of the nursing lecturer as researcher of their teaching. This article explores the difference between evaluation and evaluation research and argues for the need to use educational research methods when undertaking evaluation research into innovations in teaching, learning and assessment. A new model for educational evaluation research is presented together with two case examples of the model in use. The model has been tested on over 30 research studies into innovations in teaching, learning and assessment over the past 8 years.

    With the arrival of a technologically proficient generation of learners (often described with the moniker "digital natives") into Canadian medical schools and residency programs, there is an increasing trend toward harnessing technology to enhance education and increase teaching efficiency. We present an instructional method that allows medical educators to "reverse" the traditional classroom paradigm. Imagine that prior to an academic half-day session, learners watch an e-lecture on their own time; then during class, they do "homework" with tailored consultations from a content expert. The reverse classroom uses simple, readily accessible technology to allow faculty members to engage learners in high-order learning such as information analysis and synthesis. With this instructional method, the inefficient, repetitious delivery of recurring core lectures is no longer required. The reverse classroom is an effective instructional method. Using this technique, learners engage in high-order learning and interaction with teachers, and teachers are able to optimally share their expertise.

    Many of the important properties and uses of ice that fascinate cryospheric scientists actually depend on impurities that are present: isotopic variants of water molecules, small amounts of soluble and insoluble material derived from the aerosol and gas phase, and the trace constituents of the air bubbles that make up around 10% of the volume of ice at atmospheric pressure. In this lecture, I will first discuss how these impurities, and their location within the ice structure, affect local properties of the ice such as the electrical conductivity and mechanical strength, which scale up to give ice sheets their geophysical properties. I will then consider how the concentrations of different impurities are used to give unique records of palaeoclimate and palaeoenvironmental properties, extending so far 800,000 years back in time. This will be illustrated particularly with data from the EPICA Dome C ice core. Bringing the presentation full circle (and towards Agassiz!), I will discuss how the data from ice cores and other palaeoclimatic archives are starting to lead us towards understanding of the causes of the most prominent feature of late Quaternary climate: the huge glacial/interglacial swings in temperature, that are accompanied by the waxing and waning, roughly every 100,000 years, of great northern hemisphere ice sheets.

    Objective. To compare the impact of 2 different teaching and learning methods on student mastery of learning objectives in a pharmacotherapy module in the large classroom setting. Design. Two teaching and learning methods were implemented and compared in a required pharmacotherapy module for 2 years. The first year, multiple interactive mini-cases with inclass individual assessment and an abbreviated lecture were used to teach osteoarthritis; a traditional lecture with 1 inclass case discussion was used to teach gout. In the second year, the same topics were used but the methods were flipped. Student performance on pre/post individual readiness assessment tests (iRATs), case questions, and subsequent examinations were compared each year by the teaching and learning method and then between years by topic for each method. Students also voluntarily completed a 20-item evaluation of the teaching and learning methods. Assessment. Postpresentation iRATs were significantly higher than prepresentation iRATs for each topic each year with the interactive mini-cases; there was no significant difference in iRATs before and after traditional lecture. For osteoarthritis, postpresentation iRATs after interactive mini-cases in year 1 were significantly higher than postpresentation iRATs after traditional lecture in year 2; the difference in iRATs for gout per learning method was not significant. The difference between examination performance for osteoarthritis and gout was not significant when the teaching and learning methods were compared. On the student evaluations, 2 items were significant both years when answers were compared by teaching and learning method. Each year, students ranked their class participation higher with interactive cases than with traditional lecture, but both years they reported enjoying the traditional lecture format more. Conclusion. Multiple interactive mini-cases with an abbreviated lecture improved immediate mastery of learning objectives compared to

    The ability to conceptualize 3D shapes is central to understanding biological processes. The concept that the structure of a biological molecule leads to function is a core principle of the biochemical field. Visualisation of biological molecules often involves vocal explanations or the use of two dimensional slides and video presentations. A deeper understanding of these molecules can however be obtained by the handling of objects. 3D printed biological molecules can be used as active learning tools to stimulate engagement in large group lectures. These models can be used to build upon initial core knowledge which can be delivered in either a flipped form or a more didactic manner. Within the teaching session the students are able to learn by handling, rotating and viewing the objects to gain an appreciation, for example, of an enzyme’s active site or the difference between the major and minor groove of DNA. Models and other artefacts can be handled in small groups within a lecture theatre and act as a focal point to generate conversation. Through the approach presented here core knowledge is first established and then supplemented with high level problem solving through a "Think-Pair-Share" cooperative learning strategy. The teaching delivery was adjusted based around experiential learning activities by moving the object from mental cognition and into the physical environment. This approach led to students being able to better visualise biological molecules and a positive engagement in the lecture. The use of objects in teaching allows the lecturer to create interactive sessions that both challenge and enable the student. PMID:27366318

  12. Lecture-Capture Software and the Teaching of Soils

    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
