    Adams, Jeffrey P.; Bailey, Janelle M.; Prather, Edward E.; Slater, Timothy F.

    Contemporary science education reforms suggest that teacher-centered lectures are ineffective when compared to student-centered active learning approaches. Funded by the U.S. National Science Foundation this project has developed a series of innovative classroom instructional materials for the introductory science survey course for non-science and pre-service education majors as well as secondary school astronomy courses. The materials package called Lecture-Tutorials for Introductory Astronomy is a self-contained classroom-ready product for use with collaborative student learning groups. The materials are designed specifically to be easily integrated into the conventional lecture course. As such this product directly addresses the needs of busy faculty and heavily-loaded teaching faculty for effective student-centered classroom-ready materials that do not require a drastic course revision for implementation. Each activity requires no equipment and takes 10 to 15 minutes of class time. Students are asked to reason about difficult concepts in astronomy while working in pairs and to discuss their ideas openly. The 30 Lecture-Tutorials for Introductory Astronomy are based upon educational research on student misconceptions demonstrated effective instructional strategies and extensive pilot and field-testing. Funding for the project was made available by NSF CCLI #9952232 and NSF Geosciences Education #9907755.

    The Lecture-Tutorial curriculum development project produced a set of 29 learner-centered classroom instructional materials for a large-enrollment introductory astronomy survey course for non-science majors. The Lecture-Tutorials are instructional materials intended for use by collaborative student learning groups, and are designed to be integrated into existing courses with conventional lectures. These instructional materials offer classroom-ready learner-centered activities that do not require any outside equipment or drastic course revision for implementation. Each 15-minute Lecture-Tutorial poses a sequence of conceptually challenging, Socratic dialogue-driven questions, along with graphs and data tables, all designed to encourage students to reason critically about difficult concepts in astronomy. The materials are based on research into student beliefs and reasoning difficulties, and use proven instructional strategies. The Lecture-Tutorials have been field-tested for effectiveness at various institutions, which represent a wide range of student populations and instructional settings. In addition to materials development, a second effort of this project focused on the assessment of changes in students' conceptual understanding and attitudes toward learning astronomy as a result of both lecture and the subsequent use of Lecture-Tutorials. Quantitative and qualitative assessments were completed using a precourse, postlecture, and post-Lecture-Tutorial instrument, along with focus group interviews, respectively. Collectively, the evaluation data illustrate that conventional lectures alone helped students make statistically significant--yet unsatisfactory--gains in understanding (with students scoring at only the 50% level postlecture). Further, the data illustrate that the use of Lecture-Tutorials helped students achieve statistically significant gains beyond those attained after lecture (with students scoring at the 70% level post-Lecture-Tutorial

    Light and spectroscopy are among the most important and frequently taught topics in introductory college-level general education astronomy courses (hereafter Astro 101). This is due to the fact that the vast majority of observational data studied by astronomers arrives at Earth in the form of light. While there are many processes by which matter can emit and absorb light, Astro 101 courses typically limit their instruction to the Bohr model of the atom and electron energy level transitions. In this paper, we report on the development of a new Lecture-Tutorial to help students learn about other processes that are responsible for the emission and absorption of light, namely molecular rotations, molecular vibrations, and the acceleration of charged particles by magnetic fields. Note that this paper primarily focuses on describing the variety of representations and reasoning tasks designed for this Lecture-Tutorial; while the end of this paper highlights some data that are suggestive of the Lecture-Tutorial's effectiveness, our more comprehensive analysis of its efficacy will be presented in a future publication.

  8. "ASTRO 101" Course Materials 2.0: Next Generation Lecture Tutorials and Beyond

    Slater, Stephanie; Grazier, Kevin

    2015-01-01

    Early efforts to create course materials were often local in scale and were based on "gut instinct," and classroom experience and observation. While subsequent efforts were often based on those same instincts and observations of classrooms, they also incorporated the results of many years of education research. These "second generation" course materials, such as lecture tutorials, relied heavily on research indicating that instructors need to actively engage students in the learning process. While imperfect, these curricular innovations, have provided evidence that research-based materials can be constructed, can easily be disseminated to a broad audience, and can provide measureable improvement in student learning across many settings. In order to improve upon this prior work, next generation materials must build upon the strengths of these innovations while engineering in findings from education research, cognitive science, and instructor feedback. A next wave of materials, including a set of next generation lecture tutorials, have been constructed with attention to the body of research on student motivation, and cognitive load; and they are responsive to our body of knowledge on learning difficulties related to specific content in the domain. From instructor feedback, these materials have been constructed to have broader coverage of the materials typically taught in an ASTRO 101 course, to take less class time, and to be more affordable for students. This next generation of lecture tutorials may serve as a template of the ways in which course materials can be reengineered to respond to current instructor and student needs.

  9. Assessing the flexibility of research-based instructional strategies: Implementing tutorials in introductory physics in the lecture environment

    2014-03-01

    Materials from Tutorials in Introductory Physics, originally designed and implemented by the Physics Education Group at the University of Washington, were used in modified form as interactive lectures under conditions significantly different from those suggested by the curriculum developers. Student learning was assessed using tasks drawn from the physics education research literature. Use of tutorials in the interactive lecture format yielded gains in student understanding comparable to those obtained through the canonical tutorial implementation at the University of Washington, suggesting that student engagement with the intellectual steps laid out in the tutorials, rather than the specific strategies used in facilitating such engagement, plays the central role in promoting student learning. We describe the implementation details and assessment of student learning for two different tutorials: one focused on mechanical waves, used at North Dakota State University, and one on Galilean relativity, used at Western Washington University. Also discussed are factors that may limit the generalizability of the results.

  10. Ocean noise and marine mammals: A tutorial lecture

    D'Spain, Gerald; Wartzok, Douglas

    2004-10-01

    The effect of man-made sound on marine mammals has been surrounded by controversy over the past decade. Much of this controversy stems from our lack of knowledge of the effects of noise on marine life. Ocean sound is produced during activities of great benefit to humans: commerce, exploration for energy reserves, national defense, and the study of the ocean environment itself. However, some recent strandings of marine mammals have been associated with the occurrence of human-generated sound. The documented increase of man-made sound in the ocean suggests the potential for more extensive though subtler effects than those observed in the mass strandings. The purpose of this tutorial is to present the scientific issues pertaining to ocean noise and marine mammals. Basic physics of sound in the ocean and long term trends of ocean sound will be presented. The biology of marine mammals, particularly their production, reception and use of sound in monitoring their environment, social interactions, and echolocation, will be reviewed. This background information sets the stage for understanding the effects of man-made sound on marine mammals. The extensive gaps in current knowledge with respect to marine mammal distribution and behavioral and physiological responses to sound will highlight research needs.

    The Lecture-Tutorial Coherency Project investigates the correlation between correctness and coherency in students' written Lecture-Tutorial (LT) responses, and their understanding of introductory astronomy content. Astronomy education researchers, including undergraduate students from the CAE Ambassadors Program (former Astro 101 students who serve as instructional assistants), created rubrics designed to assess the correctness and coherency of students' written explanations of reasoning for three LT questions from the 2010 semester and four LT questions from the 2011 semester. We used these rubrics to score the LT responses of over 1300 students. We compared the average of students' written correctness and coherency scores to their responses to LSCI questions and conceptually difficult and closely related multiple-choice exam items. Our data indicates no significant difference in the correctness of student responses between students who write weak vs. robust scientific explanations of reasoning. However, it is worth noting that the average LSCI normalized gain scores and average exam-question scores for this population of students (regardless of their correctness and coherency cores) is higher than what is typically achieved by students after traditional lecture-based instruction or from low-interactivity classrooms. These results suggest that the cognitive engagement required to complete the Socratic-dialog driven LT activities is sufficient to promote higher levels of conceptual understanding regardless of whether the students actually write out their explanations.

  12. Supporting Survey Courses with Lecture-Tutorials and Backwards-Faded Scaffolded Inquiry

    NASA Astrophysics Data System (ADS)

    Slater, T. F.; Slater, S. J.

    2013-12-01

    In the course of learning science, it is generally accepted that successful science learning experiences should result in learners developing a meaningful understanding of the nature of science as inquiry where: (i) students are engaged in questions; (ii) students are designing plans to pursue data; and (iii) students are generating and defending conclusions based on evidence they have collected. Few of these learning targets can be effectively reached through a professor-centered, information download lecture. In response to national reform movements calling for professors to adopt teaching strategies and learning environments where non-science majors and future teachers can actively engage in scientific discourse, scholars with the CAPER Center for Astronomy & Physics Education Research have leveraged NSF DUE funding over the last decade to develop and systematically field-test two separate instructional approaches. The first of these is called Lecture-Tutorials (NSF 99077755 and NSF 9952232) . These are self-contained, classroom-ready, collaborative group activities. The materials are designed specifically to be easily integrated into the lecture course and directly address the needs of busy and heavily-loaded teaching faculty for effective, student-centered, classroom-ready materials that do not require a drastic course revision for implementation. Students are asked to reason about difficult concepts, while working in pairs, and to discuss their ideas openly. The second of these is a series of computer-mediated, inquiry learning experiences for non-science majoring undergraduates based upon an inquiry-oriented teaching approach framed by the notions of backwards faded-scaffolding as an overarching theme for instruction (NSF 1044482). Backwards faded-scaffolding is a strategy where the conventional and rigidly linear scientific method is turned on its head and students are first taught how to create conclusions based on evidence, then how experimental design

  13. An investigation into introductory astronomy students' difficulties with cosmology, and the development, validation, and efficacy of a new suite of cosmology lecture-tutorials

    NASA Astrophysics Data System (ADS)

    Wallace, Colin S.

    This study reports the results of the first systematic investigation into Astro 101 students' conceptual and reasoning difficulties with cosmology. We developed four surveys with which we measured students' conceptual knowledge of the Big Bang, the expansion and evolution of the universe, and the evidence for dark matter. Our classical test theory and item response theory analyses of over 2300 students' pre- and post-instruction responses, combined with daily classroom observations, videotapes of students working in class, and one-on-one semi-structured think-aloud interviews with nineteen Astro 101 students, revealed several common learning difficulties. In order to help students overcome these difficulties, we used our results to inform the development of a new suite of cosmology lecture-tutorials. In our initial testing of the new lecture-tutorials at the University of Colorado at Boulder and the University of Arizona, we found many cases in which students who used the lecture-tutorials achieved higher learning gains (as measured by our surveys) at statistically significant levels than students who did not. Subsequent use of the lecture-tutorials at a variety of colleges and universities across the United States produced a wide range of learning gains, suggesting that instructors' pedagogical practices and implementations of the lecture-tutorials significantly affect whether or not students achieve high learning gains.

    Liu, Jing; Zhong, Weicai; Jiao, Licheng

    2006-03-01

    Since all graphs in the 1993 DIMACS graph coloring challenge are undirected, each edge should be only counted once. However, in some files each edge is counted once, whereas in others each edge is counted twice; so a systematical check on the DIMACS challenge is made to eliminate the inconsistencies. Besides, the experimental results of a previous paper by Blas et al. counted each violated edges twice and neglected the inconsistencies in the DIMACS challenge. So the correct experimental results of a previous paper by Blas et al are also given. PMID:16566482

    1980-09-01

    Four tutorial lectures were delivered to provide an introduction to high energy positron-electron annihilation physics, and to serve as a foundation for more advanced lectures. The first lecture discusses three subjects: the parameters of e{sup +}e{sup -} storage rings that are directly relevant to experiments, the physics of e{sup +}e{sup -} one-photon exchange as illustrated by the reaction e{sup +}e{sup -} ..-->.. ..mu..{sup +}..mu..{sup -}, and the naive quark model for the reaction e{sup +}e{sup -} ..-->.. hadrons. The second lecture is devoted to heavy leptons: the status of the tau lepton, and the status of the search for heavier leptons. The third lecture discusses the nonrelativistic quantum mechanics of heavy quark-antiquark systems - the psi/J particle family and the T particle family. As e{sup +}e{sup -} colliding beams machines attain very high energy, E{sub c.m.} greater than or equal to 50 GeV, e{sup +}e{sup -} annihilation will occur through the weak interactions as well as through the electromagnetic interaction; this will allow the study of the weak interactions and the study of any new particle related to, or produced through, the weak interactions. Lecture 4 discusses this physics at an energy corresponding to the mass of the Z{sup 0} intermediate boson, and then discusses the physics at yet higher energy. The lecture concludes with a description of the capabilities and limitations of the e{sup +}e{sup -} colliding beams machines needed to attain this very high energy - both storage rings and colliding linear accelerators.

  1. Creating Lecture Tutorials for the Introductory Geoscience Classroom with Data Found on the Digital Library for Earth System Education (DLESE) Website

    NASA Astrophysics Data System (ADS)

    Kortz, K. M.; Jager, J. M.

    2006-05-01

    Lecture Tutorials (LTs) are short, interactive materials used during lectures that guide student learning and challenge students to think about their own misconceptions. They are designed to be used by instructors as a simple way to increase the amount of interactive learning in their classroom. We developed several geoscience LTs, using data sets found on the Digital Library for Earth System Education (DLESE) website when possible, in order to address the problems of student misconceptions and lack of appreciation of science. After a short lecture, the students were given 3 to 4 multiple choice questions about the material covered. They then worked in groups on an LT, participated in a class discussion and answered a second similar question set to test for additional learning. Based on the results of one author's students, the materials were revised and retested with the other's students. Student interviews were conducted to determine the role data sets played in changing student attitudes toward science. LTs in this study were written with two different purposes. One set focused on data interpretation and scientific methods using real-world data sets found on DLESE. We found little to no increase in pre-LT and post-LT performance on the question sets when these LTs were used. The other set of LTs specifically tackled misconceptions about a single geologic topic. Students showed a significant increase in pre-LT and post-LT learning based on the questions sets when these LTs were used. LTs that successfully decreased student misconceptions did not require the use of real-world data sets. We identified several factors influencing student performance on the pre- and post-LT questions, in addition to whether or not the LT focused on including data sets or tackling misconceptions. The distracters in the questions need to include the student misconceptions to verify the students have changed their understanding. This demonstrates a need for a large database of well

    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.

    OBJECTIVE In a study conducted over 3 large symposia on intensive review of internal medicine, we previously assessed the features that were most important to course participants in evaluating the quality of a lecture. In this study, we attempt to validate these observations by assessing prospectively the extent to which ratings of specific lecture features would predict the overall evaluation of lectures. MEASUREMENTS AND MAIN RESULTS After each lecture, 143 to 355 course participants rated the overall lecture quality of 69 speakers involved in a large symposium on intensive review of internal medicine. In addition, 7 selected participants and the course directors rated specific lecture features and overall quality for each speaker. The relations among the variables were assessed through Pearson correlation coefficients and cluster analysis. Regression analysis was performed to determine which features would predict the overall lecture quality ratings. The features that most highly correlated with ratings of overall lecture quality were the speaker's abilities to identify key points (r = .797) and be engaging (r = .782), the lecture clarity (r = .754), and the slide comprehensibility (r = .691) and format (r = .660). The three lecture features of engaging the audience, lecture clarity, and using a case-based format were identified through regression as the strongest predictors of overall lecture quality ratings (R2= 0.67, P = 0.0001). CONCLUSIONS We have identified core lecture features that positively affect the success of the lecture. We believe our findings are useful for lecturers wanting to improve their effectiveness and for educators who design continuing medical education curricula. PMID:10886470

    2014-12-04

    THE SAME REQUEST WILL BE SENT TO BOTH NSF AND DOE TO EACH SUPPORT $35K. The third annual Community Earth System Model (CESM) tutorial for students and early career scientists was held from 30 July to 3 August, 2012. This event was extremely successful and, as for the tutorials in previous years, there was a greater demand than could be met. This indicates a continuing need for a tutorial of this type and we anticipate that the 2013 tutorial will be well received. The tutorial will include lectures on simulating the climate system and practical sessions on running CESM, modifying components, and analyzing data. These will be targeted to the graduate student level. Attendance will be limited to a maximum of 80 students with financial support for up to 40 students. Attendees will be balanced across institutions.

  6. Teasing out the effect of tutorials via multiple regression

    NASA Astrophysics Data System (ADS)

    Chasteen, Stephanie V.

    2012-02-01

    We transformed an upper-division physics course using a variety of elements, including homework help sessions, tutorials, clicker questions with peer instruction, and explicit learning goals. Overall, the course transformations improved student learning, as measured by our conceptual assessment. Since these transformations were multi-faceted, we would like to understand the impact of individual course elements. Attendance at tutorials and homework help sessions was optional, and occurred outside the class environment. In order to identify the impact of these optional out-of-class sessions, given self-selection effects in student attendance, we performed a multiple regression analysis. Even when background variables are taken into account, tutorial attendance is positively correlated with student conceptual understanding of the material - though not with performance on course exams. Other elements that increase student time-on-task, such as homework help sessions and lectures, do not achieve the same impacts.

    1991-09-01

    The importance of neural networks has grown dramatically during this decade. While only a few years ago they were primarily of academic interest, now dozens of companies and many universities are investigating the potential use of these systems and products are beginning to appear. The idea of building a machine whose architecture is inspired by that of the brain has roots which go far back in history. Nowadays, technological advances of computers and the availability of custom integrated circuits, permit simulations of hundreds or even thousands of neurons. In conjunction, the growing interest in learning machines, non-linear dynamics and parallel computation spurred renewed attention in artificial neural networks. Many tentative applications have been proposed, including decision systems (associative memories, classifiers, data compressors and optimizers), or parametric models for signal processing purposes (system identification, automatic control, noise canceling, etc.). While they do not always outperform standard methods, neural network approaches are already used in some real world applications for pattern recognition and signal processing tasks. The tutorial is divided into six lectures, that where presented at the Third Graduate Summer Course on Computational Physics (September 3-7, 1990) on Parallel Architectures and Applications, organized by the European Physical Society: (1) Introduction: machine learning and biological computation. (2) Adaptive artificial neurons (perceptron, ADALINE, sigmoid units, etc.): learning rules and implementations. (3) Neural network systems: architectures, learning algorithms. (4) Applications: pattern recognition, signal processing, etc. (5) Elements of learning theory: how to build networks which generalize. (6) A case study: a neural network for on-line recognition of handwritten alphanumeric characters.

    NASA Astrophysics Data System (ADS)

    Pollock, Steven J.

    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 'learning-by-doing' treatment planning tutorial for medical physicists.

    PubMed

    Meyer, J; Hartmann, B; Kalet, I

    2009-06-01

    A framework for a tutorial for treatment planning in radiation oncology physics was developed, based on the University of Washington treatment planning system Prism. The tutorial is aimed at students in Medical Physics to accompany the lectures on treatment planning to enhance their theoretical knowledge. A web-based layout was chosen to allow independent work of the students. The tutorial guides the students through three different learning modules, designed mainly to enhance their understanding of the processes involved in treatment planning but also to learn the specific features of a modern treatment planning system. Each of the modules contains four units, with the aim to introduce the relevant Prism features, practice skills in different tasks and finally check the learning outcomes with a challenge and a self-scoring quiz. A survey for students' feedback completes the tutorial. Various tools and learning methods help to create an interactive, appealing learning environment, in which the emphasis is shifted from teacher-centred to student-centred learning paradigms. In summary, Prism lends itself well for educational purposes. The tutorial covers all main aspects of treatment planning. In its current form the tutorial is self-contained but still adjustable and expandable. The tutorial can be made available upon request to the authors. PMID:19623863

    An assessment is undertaken of recent approaches to the prediction of the interplanetary consequences of coronal disturbances, with attention to the relationships of shocks and energetic particles to coronal transients, of proton events to gamma-ray and microwave bursts, of geomagnetic storms to filament eruptions, and of solar wind increases to the flare site magnetic field direction. A discussion is given concerning the novel phenomenon of transient coronal holes, which appear astride the long decay enhancements of 2-50 A X-ray emission following H-alpha filament eruptions. These voids in the corona are similar to long-lived coronal holes, which are the sources of high speed solar wind streams. The transient coronal holes may also be associated with transient solar wind speed increases.

    Greater emphasis is being placed on reducing both the carbon footprint and energy cost of buildings. A building's energy usage depends upon many factors one of the most important is the local weather and climate conditions to which it's electrical, heating and air conditioning systems must respond. Incorporating renewable energy systems, including solar systems, to supplement energy supplies and increase energy efficiency is important to saving costs and reducing emissions. Also retrofitting technologies to buildings requires knowledge of building performance in its current state, potential future climate state, projection of potential savings with capital investment, and then monitoring the performance once the improvements are made. RETScreen Plus is a performance analysis software module that supplies the needed functions of monitoring current building performance, targeting projected energy efficiency improvements and verifying improvements once completed. This tutorial defines the functions of RETScreen Plus as well as outlines the general procedure for monitoring and reporting building energy performance.

  14. UH-60 Airloads Program Tutorial

    NASA Technical Reports Server (NTRS)

    Bousman, William G.

    2009-01-01

    From the fall of 1993 to late winter of 1994, NASA Ames and the U.S. Army flew a flight test program using a UH-60A helicopter with extensive instrumentation on the rotor and blades, including 242 pressure transducers. Over this period, approximately 30 flights were made, and data were obtained in level flight, maneuver, ascents, and descents. Coordinated acoustic measurements were obtained with a ground-acoustic array in cooperation with NASA Langley, and in-flight acoustic measurements with a YO-3A aircraft. NASA has sponsored the creation of a "tutorial' which covers the depth and breadth of the flight test program with a mixture of text and graphics. The primary purpose of this tutorial is to introduce the student to what is known about rotor aerodynamics based on the UH-60A measurements. The tutorial will also be useful to anyone interested in helicopters who would like to have more detailed knowledge about helicopter aerodynamics.

  15. Renormalization Group Tutorial

    NASA Technical Reports Server (NTRS)

    Bell, Thomas L.

    2004-01-01

    Complex physical systems sometimes have statistical behavior characterized by power- law dependence on the parameters of the system and spatial variability with no particular characteristic scale as the parameters approach critical values. The renormalization group (RG) approach was developed in the fields of statistical mechanics and quantum field theory to derive quantitative predictions of such behavior in cases where conventional methods of analysis fail. Techniques based on these ideas have since been extended to treat problems in many different fields, and in particular, the behavior of turbulent fluids. This lecture will describe a relatively simple but nontrivial example of the RG approach applied to the diffusion of photons out of a stellar medium when the photons have wavelengths near that of an emission line of atoms in the medium.

  16. A quick SEED tutorial

    USGS Publications Warehouse

    Ringler, Adam; Evans, John R.

    2015-01-01

    A number of different government-funded seismic data centers offer free open-access data (e.g., U.S. Geological Survey, National Earthquake Information Center, the Incorporated Research Institutions for Seismology (IRIS), and Data Management System), which can be freely downloaded and shared among different members of the community (Lay, 2009). To efficiently share data, it is important that different data providers follow a common format. The Standard for the Exchange of Earthquake Data (SEED) provides one such format for storing seismic and other geophysical data. The SEED format is widely used in earthquake seismology; however, SEED and its structure can be difficult for many first-time users (ourselves included). Below is a quick tutorial that outlines the basic structure of SEED format. This write-up is in no way intended to replace the comprehensive SEED manual (Ahern et al., 2009), and instead of going into the details of any specific part of the SEED format we refer the reader to the manual for additional details. The goal of this write-up is to succinctly explain the basic structure of SEED format as well as the associated jargon, as most commonly used now, in a colloquial way so that novice users of SEED can become more familiar with the format and its application quickly. Our goal is to give the reader the necessary background so that when problems or questions about SEED format arise they will have some understanding of where they should look for more details or from where the problem might be stemming. As a secondary goal, we hope to help the reader become familiar with the SEED manual (Ahern et al., 2009), which contains detailed information about all aspects of the SEED format.

  17. TUTORIAL ON NETWORK GENOMICS.

    SciTech Connect

    Forst, C.

    2001-01-01

    With the ever-increasing genomic information pouring into the databases researchers start to look for pattern in genomes. Key questions are the identification of function. In the past function was mainly understood to be assigned to a single gene isolated from other cellular components or mechanisms. Sequence comparison fo single genes and their products (proteins) as well as of intergenic space are a consequence of a well established one-gene one-function interpretation. prediction of function solely by sequence similarity searches are powerful techniques that initiated the advent of bioinformatics and computational biology. Seminal work on sequence alignment by Temple Smith and Michael Waterman [33] and sequence searches with the BLAST algorithm by Altschul et al. [2] provide essential methods for sequence based determination of function. Similar outstanding contributions to determination of function have been archived in the area of structure prediction, molecular modeling and molecular dynamics. Techniques covering ab initio and homology modeling up to biophysical interpretation of long-run molecular dynamics simulations are mentioned ehre. With the ever-increasing number of information of different genetic/genomic origin, new aspect are looked for that deviate from the single gene at a time method. Especially with the identification of surprisingly few human genes the emerging perception in the scientific community that the concept of function has to be extended to include other sequence based as well as non-sequenced based information. A schema of determination of function by different concepts is shown in Figure 1. The tutorial is comprised of the following sections: The first two sections discuss the differences between genomic and non-genomic based context information, section three will cover combined methods. Finally, section four lsits web-resources and databases. All presented approaches extensively employ comparative methods.

  3. Implementing Learning Assistants and Tutorials in the Laboratory Environment

    NASA Astrophysics Data System (ADS)

    Stewart, John; Henderson, Rachel; Miller, Paul

    2016-03-01

    This talk describes the results of a novel implementation of a Learning Assistant (LA) program where the LAs facilitated the presentation of the Tutorials in Introductory Physics as part of an otherwise traditional laboratory. LAs received both general training in the teaching of science and specific training in the presentation of the Tutorials. The LAs acted as the lead laboratory instructor for one hour each lab. The program required very little interaction from the lecturer. The program showed a substantial increase in learning gains on the Force and Motion Conceptual Inventory in the first semester course, but weaker improvement of learning gains on the Conceptual Survey of Electricity and Magnetism in the second semester course. Multiple linear regression showed that gender, student ability, and whether the student was on-sequence were significant regressors. The instructor was a substantial random effect (SD = 0 . 10), but the teaching assistant (SD = 0 . 00) and learning assistant (SD = 0 . 01) were much weaker random effects on the normalized gain. The instructor standing (tenure-track, teaching faculty, or adjunct) was a weakly significant regressor (p < 0 . 05).

The results of this research have guided the design of a set of tutorials to supplement lecture and laboratory instruction in a traditional introductory physics course. Examples will be given of how some serious difficulties in physical optics are being addressed through these tutorials. Ongoing assessment of student learning indicates that these materials are effective at addressing many of the student difficulties that were found to persist after instruction in lecture and laboratory. * This work has been funded in part by NSF Grants DUE 9354501 and DUE 9727648, which include support from other Divisions of EHR and the Physics Division of MPS.

    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.

    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.

    Sundance is a system of software components that allows construction of an entire parallel simulator and its derivatives using a high-level symbolic language. With this high-level problem description, it is possible to specify a weak formulation of a PDE and its discretization method in a small amount of user-level code; furthermore, because derivatives are easily available, a simulation in Sundance is immediately suitable for accelerated PDE-constrained optimization algorithms. This paper is a tutorial for setting up and solving linear and nonlinear PDEs in Sundance. With several simple examples, we show how to set up mesh objects, geometric regions for BC application, the weak form of the PDE, and boundary conditions. Each example then illustrates use of an appropriate solver and solution visualization.

    Graduate medical students of India are taught Biochemistry by didactic lectures and they hardly get any opportunity to clarify their doubts and reinforce the concepts which they learn in these lectures. We used a combination of teaching-learning (T-L) methods (open book assignment followed by group tutorials) to study their efficacy in improving the learning outcome. About 143 graduate medical students were classified into low (<50%: group 1, n = 23), medium (50-75%: group 2, n = 74), and high (>75%: group 3, n = 46) achievers, based on their internal assessment marks. After the regular teaching module on the topics "Vitamins and Enzymology", all the students attempted an open book assignment without peer consultation. Then all the students participated in group tutorials. The effects on the groups were evaluated by pre and posttests at the end of each phase, with the same set of MCQs. Gain from group tutorials and overall gain was significantly higher in the low achievers, compared to other groups. High and medium achievers obtained more gain from open book assignment, than group tutorials. The overall gain was significantly higher than the gain obtained from open book assignment or group tutorials, in all three groups. All the three groups retained the gain even after 1 week of the exercise. Hence, optimal use of novel T-L methods (open book assignment followed by group tutorials) as revision exercises help in strengthening concepts in Biochemistry in this oft neglected group of low achievers in graduate medical education. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):321-325, 2016.

    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.

    2004-05-01

    The Trilinos Project is an effort to facilitate the design, development, integration and ongoing support of mathematical software libraries. The goal of the Trilinos Project is to develop parallel solver algorithms and libraries within an object-oriented software framework for the solution of large-scale, complex multiphysics engineering and scientific applications. The emphasis is on developing robust, scalable algorithms in a software framework, using abstract interfaces for flexible interoperability of components while providing a full-featured set of concrete classes that implement all the abstract interfaces. This document introduces the use of Trilinos, version 4.0. The presented material includes, among others, the definition of distributed matrices and vectors with Epetra, the iterative solution of linear systems with AztecOO, incomplete factorizations with IF-PACK, multilevel and domain decomposition preconditioners with ML, direct solution of linear system with Amesos, and iterative solution of nonlinear systems with NOX. The tutorial is a self-contained introduction, intended to help computational scientists effectively apply the appropriate Trilinos package to their applications. Basic examples are presented that are fit to be imitated. This document is a companion to the Trilinos User's Guide [20] and Trilinos Development Guides [21,22]. Please note that the documentation included in each of the Trilinos' packages is of fundamental importance.

    Board, Editorial

    2013-06-01

    The Editorial Board of Laser Physics is very pleased to announce that we have started publishing our new tutorial paper series. The first tutorial, 'Theory of atoms: basics of quantum statistics' by V I Yukalov (2013 Laser Phys. 23 062001), presents the basic techniques of quantum statistics that are necessary for the correct description of cold atomic systems. This introductory article is intended to be followed by further tutorials on the same topic, where general techniques will be illustrated by practical applications to finite quantum systems with Bose-Einstein condensate and applications to degenerate Fermi systems with pairing. Special attention will be paid to the description of cold trapped atoms. We hope that this tutorial will be interesting and useful to all scholars, researchers, postdoctoral fellows and students involved in research dealing with the physics of cold trapped atoms and molecules, the theory of finite quantum systems and various related applications. The Editorial Board would like to encourage our readers to provide us with your feedback and requests for future tutorials in areas of your particular interest. Please forward all your comments, suggestions and requests to editor@lasphys.com. With our best wishes, The Editorial Board

  3. Interactive Problem Solving Tutorials Through Visual Programming

    NASA Astrophysics Data System (ADS)

    Undreiu, Lucian; Schuster, David; Undreiu, Adriana

    2008-10-01

    We have used LabVIEW visual programming to build an interactive tutorial to promote conceptual understanding in physics problem solving. This programming environment is able to offer a web-accessible problem solving experience that enables students to work at their own pace and receive feedback. Intuitive graphical symbols, modular structures and the ability to create templates are just a few of the advantages this software has to offer. The architecture of an application can be designed in a way that allows instructors with little knowledge of LabVIEW to easily personalize it. Both the physics solution and the interactive pedagogy can be visually programmed in LabVIEW. Our physics pedagogy approach is that of cognitive apprenticeship, in that the tutorial guides students to develop conceptual understanding and physical insight into phenomena, rather than purely formula-based solutions. We demonstrate how this model is reflected in the design and programming of the interactive tutorials.

  8. Combination of didactic lectures and review sessions in endocrinology leads to improvement in student performance as measured by assessments.

    PubMed

    Qureshi, Ayisha; Cozine, Cassy; Rizvi, Farwa

    2013-03-01

    There can be no single best way of learning, and each teaching mode has its own merits and demerits. Didactic lectures in and of themselves are insufficient, whereas a problem-based tutorial alone can be as ineffective. This study was conducted to determine if a problem-based review after didactic lectures would lead to better student performance. To compare performance, the same student group was taught three units of endocrinology (growth hormone, thyroid hormone, and diabetes). Students were divided into the following three groups: diabetes didactic lectures only, growth hormone didactic lectures plus review, and thyroid hormone didactic lectures plus review. All three topics were covered in the didactic lectures, but only growth hormone and thyroid hormone topics were covered in the review session. At the end of the course, all students were given formative assessments in the form of multiple-choice questions. A highly significant increase (P < 0.000) in the percentage of correct responses on the questions covering growth hormone (mean: 0.838, SD: 0.158) and thyroid hormone (mean: 0.686, SD: 0.232) compared with diabetes (mean: 0.478, SD: 0.259) was observed. In conclusion, this study provides further evidence that the combination of didactic lectures and an active review session leads to an improvement in student performance. PMID:23471255

  9. 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.

  10. RT3D tutorials for GMS users

    SciTech Connect

    Clement, T.P.; Jones, N.L.

    1998-02-01

    RT3D (Reactive Transport in 3-Dimensions) is a computer code that solves coupled partial differential equations that describe reactive-flow and transport of multiple mobile and/or immobile species in a three dimensional saturated porous media. RT3D was developed from the single-species transport code, MT3D (DoD-1.5, 1997 version). As with MT3D, RT3D also uses the USGS groundwater flow model MODFLOW for computing spatial and temporal variations in groundwater head distribution. This report presents a set of tutorial problems that are designed to illustrate how RT3D simulations can be performed within the Department of Defense Groundwater Modeling System (GMS). GMS serves as a pre- and post-processing interface for RT3D. GMS can be used to define all the input files needed by RT3D code, and later the code can be launched from within GMS and run as a separate application. Once the RT3D simulation is completed, the solution can be imported to GMS for graphical post-processing. RT3D v1.0 supports several reaction packages that can be used for simulating different types of reactive contaminants. Each of the tutorials, described below, provides training on a different RT3D reaction package. Each reaction package has different input requirements, and the tutorials are designed to describe these differences. Furthermore, the tutorials illustrate the various options available in GMS for graphical post-processing of RT3D results. Users are strongly encouraged to complete the tutorials before attempting to use RT3D and GMS on a routine basis.

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.

    Some thirty years ago acoustics lecturing started in Mexico at the National Polytechnic Institute in Mexico City, as part of the Bachelor of Science degree in Communications and Electronics Engineering curricula, including the widest program on this field in the whole country. This program has been producing acoustics specialists ever since. Nowadays many universities and superior education institutions around the country are teaching students at the B.Sc. level and postgraduate level many topics related to acoustics, such as Architectural Acoustics, Seismology, Mechanical Vibrations, Noise Control, Audio, Audiology, Music, etc. Also many institutions have started research programs in related fields, with participation of medical doctors, psychologists, musicians, engineers, etc. Details will be given on particular topics and development.

  16. Reinforcing outpatient medical student learning using brief computer tutorials: the Patient-Teacher-Tutorial sequence

    PubMed Central

    2012-01-01

    Background At present, what students read after an outpatient encounter is largely left up to them. Our objective was to evaluate the education efficacy of a clinical education model in which the student moves through a sequence that includes immediately reinforcing their learning using a specifically designed computer tutorial. Methods Prior to a 14-day Pediatric Emergency rotation, medical students completed pre-tests for two common pediatric topics: Oral Rehydration Solutions (ORS) and Fever Without Source (FWS). After encountering a patient with either FWS or a patient needing ORS, the student logged into a computer that randomly assigned them to either a) completing a relevant computer tutorial (e.g. FWS patient + FWS tutorial = “in sequence”) or b) completing the non-relevant tutorial (e.g. FWS patient + ORS tutorial = “out of sequence”). At the end of their rotation, they were tested again on both topics. Our main outcome was post-test scores on a given tutorial topic, contrasted by whether done in- or out-of-sequence. Results Ninety-two students completed the study protocol with 41 in the ‘in sequence’ group. Pre-test scores did not differ significantly. Overall, doing a computer tutorial in sequence resulted in significantly greater post-test scores (z-score 1.1 (SD 0.70) in sequence vs. 0.52 (1.1) out-of-sequence; 95% CI for difference +0.16, +0.93). Students spent longer on the tutorials when they were done in sequence (12.1 min (SD 7.3) vs. 10.5 (6.5)) though the difference was not statistically significant (95% CI diff: -1.2 min, +4.5). Conclusions Outpatient learning frameworks could be structured to take best advantage of the heightened learning potential created by patient encounters. We propose the Patient-Teacher-Tutorial sequence as a framework for organizing learning in outpatient clinical settings. PMID:22873635

  17. Lecturing with a Virtual Whiteboard

    NASA Astrophysics Data System (ADS)

    Milanovic, Zoran

    2006-09-01

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

  5. Upstream waves and particles /Tutorial Lecture/. [from shocks in interplanetary space

    NASA Technical Reports Server (NTRS)

    Russell, C. T.; Hoppe, M. M.

    1983-01-01

    The plasma waves, MHD waves, energetic electrons and ions associated with the proximity of the region upstream from terrestrial, planetary and interplanetary shocks are discussed in view of observations and current theories concerning their origin. These waves cannot be separated from the study of shock structure. Since the shocks are supersonic, they continually overtake any ULF waves created in the plasma in front of the shock. The upstream particles and waves are also of intrinsic interest because they provide a plasma laboratory for the study of wave-particle interactions in a plasma which, at least at the earth, is accessible to sophisticated probing. Insight may be gained into interstellar medium cosmic ray acceleration through the study of these phenomena.

  6. Tutorial: Clock and Clock Systems Performance Measures

    NASA Technical Reports Server (NTRS)

    Allan, David W.

    1996-01-01

    This tutorial contains basic material - familiar to many. This will be used as a foundation upon which we will build - bringing forth some new material and equations that have been developed especially for this tutorial. These will provide increased understanding toward parameter estimation of clock and clock system's performance. There is a very important International Telecommunications Union (ITU) handbook being prepared at this time which goes much further than this tutorial has time to do. I highly recommend it as an excellent resource document. The final draft is just now being completed, and it should be ready late in 1996. It is an outstanding handbook; Dr. Sydnor proposed to the ITU-R several years ago, and is the editor with my assistance. We have some of the best contributors in the community from around the world who have written the ten chapters in this handbook. The title of the handbook is 'Selection and use of Precise Frequency and Time Systems'. It will be available from the ITU secretariat in Geneva, Switzerland, but NAVTEC Seminars also plans to be a distributor.

  8. AMUM LECTURE: Therapeutic ultrasound

    NASA Astrophysics Data System (ADS)

    Crum, Lawrence A.

    2004-01-01

    The use of ultrasound in medicine is now quite commonplace, especially with the recent introduction of small, portable and relatively inexpensive, hand-held diagnostic imaging devices. Moreover, ultrasound has expanded beyond the imaging realm, with methods and applications extending to novel therapeutic and surgical uses. These applications broadly include: tissue ablation, acoustocautery, lipoplasty, site-specific and ultrasound mediated drug activity, extracorporeal lithotripsy, and the enhancement of natural physiological functions such as wound healing and tissue regeneration. A particularly attractive aspect of this technology is that diagnostic and therapeutic systems can be combined to produce totally non-invasive, imageguided therapy. This general lecture will review a number of these exciting new applications of ultrasound and address some of the basic scientific questions and future challenges in developing these methods and technologies for general use in our society. We shall particularly emphasize the use of High Intensity Focused Ultrasound (HIFU) in the treatment of benign and malignant tumors as well as the introduction of acoustic hemostasis, especially in organs which are difficult to treat using conventional medical and surgical techniques.

  9. 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. PMID:25968246

  10. The "magic" of tutorial centres in Hong Kong: An analysis of media marketing and pedagogy in a tutorial centre

    NASA Astrophysics Data System (ADS)

    Koh, Aaron

    2014-12-01

    Why do more than three-quarters of Hong Kong's senior secondary students flock to tutorial centres like moths to light? What is the "magic" that is driving the popularity of the tutorial centre enterprise? Indeed, looking at the ongoing boom of tutorial centres in Hong Kong (there are almost 1,000 of them), it is difficult not to ask these questions. This paper examines the phenomenon of tutorial centres in Hong Kong and seeks to understand what draws students to these centres. Combining theories of marketing semiotics and emotion studies, the author investigates the pivotal role of media marketing in generating the "magic" of tutorial centres, whose advertising strategy includes, for example, a display of billboard posters featuring stylishly-dressed "celebrity teachers". The author reviews some of the literature available on the subject of tutorial centres. In a case study approach, he then maps out the pedagogy he observed in an English tutorial class, seeking heuristic insights into the kind of teaching students in the study were looking for. He argues that part of the "magical" attraction of what are essentially "cram schools" is their formulaic pedagogy of teaching and reinforcing exam skills. Finally, the paper considers the social implications of the tutorial centre industry in terms of media marketing of education and unequal access to tutorial services.

    Morgentaler, H

    1989-01-01

    In this lecture, Dr. Henry Morgentaler describes how he led the fight to make abortion sage and legal in Canada. In 1967, the Canadian government began exploring possible changes in the abortion law, which at that made abortion a major crime. As president of the Humanist Fellowship of Montreal, Morgentaler presented a brief to House of Commons calling for abortion on request. His appeal attracted great media attention, and soon women started coming to Morgentaler's office seeking abortions. Risking prosecution, Morgentaler agreed to perform the operations (in the process becoming the first doctor in North America to use the vacuum suction technique). His abortion practice grew rapidly. In 1969, the Canadian government made abortion legal if approved by a committee of 3 doctors and if performed in a hospital. Though an improvement over the previous law, the new abortion law still had many deficiencies, most notably: it discriminated against women in rural areas (where the only available hospitals were Catholic), and it made getting an abortion a lengthy process, making the procedure more dangerous. Still campaigning vigorously performing abortions in his Montreal clinic, Morgentaler on charges of illegal abortion by the Quebec government. For the next 6 years, Morgentaler rode a legal roller coaster -- 3 jury acquittals were overturned or disregarded -- serving 10 months in prison throughout the ordeal (the legal battle produced the so-called Morgentaler Amendment, which stipulates that court cannot substitute its own verdict for a jury verdict of not guilty). In 1976, Quebec ended its battle with Morgentaler, who in turn launched his campaign to the rest of Canada. And in 1988, the Canadian Supreme Court rescinded the abortion low, thus affirming the dignity and equality of women. PMID:12284999

    Thank you very much. I am humbled, I am delighted; I am honored. This is every scientist's dream: to give the Nobel Lecture in Stockholm. But I would not be honest if I did not tell you that I am having a little anxiety being on this platform. I have lectured a number of times in Sweden, and I thought I would share with you some events preceding a special lecture that I gave here a few years ago. Arriving at Arlanda Airport, I waited in line at the Pass Control behind a group of businessmen in suits with briefcases. I heard the first in line asked by the control officer to state the purpose of his visit to Sweden. When the man replied "business," the officer approved and stamped his passport. One at a time, each stepped forward and was asked the same thing; each answered "business" and was approved. Eventually it was my turn, and I was dressed in rumpled clothes after spending the night in the Economy Minus section of an SAS jetliner. The officer asked me the purpose of my visit, and I said "I am here to give the von Euler Lecture at Karolinska Institute." The officer immediately looked up, stared at me, and asked, "Are you nervous?" At that point I became intensely nervous and said "Yes, I am a little nervous." The officer looked up again and stated "Well, you should be!" So if the lecturers look a little nervous, the problem is at Arlanda. PMID:16209125

    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. PMID:25746051

    Often I will listen to public radio on long drives when I am alone. Recently I happened to catch a program called "Don't Lecture Me" and it really caught my attention for several reasons. First, the speakers were all notable leaders in Physics Education Research such as Joe Redish, David Hestenes, and Eric Mazur. (See this month's WebSights column.) These folks are among many who have devoted their energies to understanding how students learn physics and how teachers can design classroom instruction and interactions to best meet the needs of learners. Second, on this particular trip, I had just observed a teacher whose class was very teacher-centered as the teacher lectured most of the class period. As we discussed this later, she expressed concern that she had to cover the material and didn't feel that she could do it without lecturing.

    The following examples of INGRID input files and results are from various sources including Doug Stillman. In many cases, they are the same as in the examples section of the INGRID manual by Doug Stillman. I have made some modest improvements so that they are all complete input files to be run with the latest version of INGRID. These files have been attached to the front end of the INGRID source as comments. I wish to invite all INGRID user's to submit any favorite input files to be included in this tutorial. Such an input file should not be too large, and the object being generated should have a natural appeal to INGRID users. Feel free to make suggestions. This tutorial will soon replace the examples section of the manual. The entire manual will be replaced a section at a time. I chose to do this section first, since it could give the most benefit in the shortest amount of time. As soon as I make INGRID interactive, I will then rewrite the section on standard parts.

  10. Understanding Graduate Teaching Assistants as Tutorial Instructors

    NASA Astrophysics Data System (ADS)

    Scherr, Rachel E.; Elby, A.

    2006-12-01

    Physics graduate teaching assistants are essential to the implementation of many collaborative active-learning environments, including tutorials. However, many TAs have trouble teaching effectively in these formats. Anecdotal evidence suggests that the problems may include inappropriate models of physics students, unproductive theories of learning, lack of experience with modern pedagogical methods, and weaknesses in understanding basic physics topics. A new research project at the University of Maryland is investigating the specific nature of TAs' experience with reform instruction using in-depth studies of TAs in course preparation sessions, in the tutorial classroom, in a weekly teaching seminar, and in reflective interviews. We find that all TAs studied recognize the insufficiency of traditional instruction to at least some extent, citing as evidence their own learning experiences, prior teaching experiences, and exposure to FCI-type data. We also observe great variability in views of the nature of physics knowledge and learning (both professed and enacted). These results are informing the development of the professional development program for physics teaching assistants at the University of Maryland.

  11. Solar Tutorial and Annotation Resource (STAR)

    2009-12-01

    We have written a software suite designed to facilitate solar data analysis by scientists, students, and the public, anticipating enormous datasets from future instruments. Our “STAR" suite includes an interactive learning section explaining 15 classes of solar events. Users learn software tools that exploit humans’ superior ability (over computers) to identify many events. Annotation tools include time slice generation to quantify loop oscillations, the interpolation of event shapes using natural cubic splines (for loops, sigmoids, and filaments) and closed cubic splines (for coronal holes). Learning these tools in an environment where examples are provided prepares new users to comfortably utilize annotation software with new data. Upon completion of our tutorial, users are presented with media of various solar events and asked to identify and annotate the images, to test their mastery of the system. Goals of the project include public input into the data analysis of very large datasets from future solar satellites, and increased public interest and knowledge about the Sun. In 2010, the Solar Dynamics Observatory (SDO) will be launched into orbit. SDO’s advancements in solar telescope technology will generate a terabyte per day of high-quality data, requiring innovation in data management. While major projects develop automated feature recognition software, so that computers can complete much of the initial event tagging and analysis, still, that software cannot annotate features such as sigmoids, coronal magnetic loops, coronal dimming, etc., due to large amounts of data concentrated in relatively small areas. Previously, solar physicists manually annotated these features, but with the imminent influx of data it is unrealistic to expect specialized researchers to examine every image that computers cannot fully process. A new approach is needed to efficiently process these data. Providing analysis tools and data access to students and the public have proven

  12. A Practical Tutorial on Modified Condition/Decision Coverage

    NASA Technical Reports Server (NTRS)

    Hayhurst, Kelly J.; Veerhusen, Dan S.; Chilenski, John J.; Rierson, Leanna K.

    2001-01-01

    This tutorial provides a practical approach to assessing modified condition/decision coverage (MC/DC) for aviation software products that must comply with regulatory guidance for DO-178B level A software. The tutorial's approach to MC/DC is a 5-step process that allows a certification authority or verification analyst to evaluate MC/DC claims without the aid of a coverage tool. In addition to the MC/DC approach, the tutorial addresses factors to consider in selecting and qualifying a structural coverage analysis tool, tips for reviewing life cycle data related to MC/DC, and pitfalls common to structural coverage analysis.

    Bedell, K.S.

    1993-01-01

    The Fermi liquid theory was first introduced by Landau in 1956 to provide a theoretical basis for the properties of strongly correlated Fermi systems. This theory has proven to be crucial for our understanding of a broad range of materials. These include liquid [sup 3]He, [sup 3]He-[sup 4]He mixtures, simple metals, heavy-fermions, and nuclear matter to name a few. In the high temperature superconductors questions have been raised regarding the applicability of Fermi liquid theory to the normal state behavior of these materials. I will not address this issue in these lectures. My focus will be to summarize the foundations of this theory and to explore the consequences. These lectures are in part a summary of the excellent review article by Baym and Pethick and the books by Pines and Nozieres and Baym and Pethick. They include as well a summary of some articles that I have authored and co-authored. In the main body of the lectures I will not make any additional references to the books or articles. In the absence of reading the original materials, my lectures should provide the essentials of a mini-course in Fermi liquid theory.

  20. Teaching More by Lecturing Less

    PubMed Central

    2005-01-01

    We carried out an experiment to determine whether student learning gains in a large, traditionally taught, upper-division lecture course in developmental biology could be increased by partially changing to a more interactive classroom format. In two successive semesters, we presented the same course syllabus using different teaching styles: in fall 2003, the traditional lecture format; and in spring 2004, decreased lecturing and addition of student participation and cooperative problem solving during class time, including frequent in-class assessment of understanding. We used performance on pretests and posttests, and on homework problems to estimate and compare student learning gains between the two semesters. Our results indicated significantly higher learning gains and better conceptual understanding in the more interactive course. To assess reproducibility of these effects, we repeated the interactive course in spring 2005 with similar results. Our findings parallel results of similar teaching-style comparisons made in other disciplines. On the basis of this evidence, we propose a general model for teaching large biology courses that incorporates interactive engagement and cooperative work in place of some lecturing, while retaining course content by demanding greater student responsibility for learning outside of class.

  5. Informed Source Separation: A Bayesian Tutorial

    NASA Technical Reports Server (NTRS)

    Knuth, Kevin H.

    2005-01-01

    Source separation problems are ubiquitous in the physical sciences; any situation where signals are superimposed calls for source separation to estimate the original signals. In h s tutorial I will discuss the Bayesian approach to the source separation problem. This approach has a specific advantage in that it requires the designer to explicitly describe the signal model in addition to any other information or assumptions that go into the problem description. This leads naturally to the idea of informed source separation, where the algorithm design incorporates relevant information about the specific problem. This approach promises to enable researchers to design their own high-quality algorithms that are specifically tailored to the problem at hand.

    Riley, Michael A.; Bonnette, Scott; Kuznetsov, Nikita; Wallot, Sebastian; Gao, Jianbo

    2012-01-01

    The authors present a tutorial description of adaptive fractal analysis (AFA). AFA utilizes an adaptive detrending algorithm to extract globally smooth trend signals from the data and then analyzes the scaling of the residuals to the fit as a function of the time scale at which the fit is computed. The authors present applications to synthetic mathematical signals to verify the accuracy of AFA and demonstrate the basic steps of the analysis. The authors then present results from applying AFA to time series from a cognitive psychology experiment on repeated estimation of durations of time to illustrate some of the complexities of real-world data. AFA shows promise in dealing with many types of signals, but like any fractal analysis method there are special challenges and considerations to take into account, such as determining the presence of linear scaling regions.

  7. Distributed Optimization and Games: A Tutorial Overview

    NASA Astrophysics Data System (ADS)

    Yang, Bo; Johansson, Mikael

    This chapter provides a tutorial overview of distributed optimization and game theory for decision-making in networked systems. We discuss properties of first-order methods for smooth and non-smooth convex optimization, and review mathematical decomposition techniques. A model of networked decision-making is introduced in which a communication structure is enforced that determines which nodes are allowed to coordinate with each other, and several recent techniques for solving such problems are reviewed. We then continue to study the impact of noncooperative games, in which no communication and coordination are enforced. Special attention is given to existence and uniqueness of Nash equilibria, as well as the efficiency loss in not coordinating nodes. Finally, we discuss methods for studying the dynamics of distributed optimization algorithms in continuous time.

  8. The Matching Law: A Tutorial for Practitioners

    PubMed Central

    Reed, Derek D; Kaplan, Brent A

    2011-01-01

    The application of the matching law has historically been limited to use as a quantitative measurement tool in the experimental analysis of behavior to describe temporally extended patterns of behavior-environment relations. In recent years, however, applications of the matching law have been translated to clinical settings and populations to gain a better understanding of how naturally-occurring events affect socially important behaviors. This tutorial provides a brief background of the conceptual foundations of matching, an overview of the various matching equations that have been used in research, and a description of how to interpret the data derived from these equations in the context of numerous examples of matching analyses conducted with socially important behavior. An appendix of resources is provided to direct readers to primary sources, as well as useful articles and books on the topic. PMID:22649575

    2016-01-01

    Distributional cost-effectiveness analysis (DCEA) is a framework for incorporating health inequality concerns into the economic evaluation of health sector interventions. In this tutorial, we describe the technical details of how to conduct DCEA, using an illustrative example comparing alternative ways of implementing the National Health Service (NHS) Bowel Cancer Screening Programme (BCSP). The 2 key stages in DCEA are 1) modeling social distributions of health associated with different interventions, and 2) evaluating social distributions of health with respect to the dual objectives of improving total population health and reducing unfair health inequality. As well as describing the technical methods used, we also identify the data requirements and the social value judgments that have to be made. Finally, we demonstrate the use of sensitivity analyses to explore the impacts of alternative modeling assumptions and social value judgments. PMID:25908564

    Experimentation is ubiquitous in the field of psychology and fundamental to the advancement of its science, and one of the biggest challenges for researchers is designing experiments that can conclusively discriminate the theoretical hypotheses or models under investigation. The recognition of this challenge has led to the development of sophisticated statistical methods that aid in the design of experiments and that are within the reach of everyday experimental scientists. This tutorial paper introduces the reader to an implementable experimentation methodology, dubbed Adaptive Design Optimization, that can help scientists to conduct “smart” experiments that are maximally informative and highly efficient, which in turn should accelerate scientific discovery in psychology and beyond.

  14. A tutorial on Bayesian Normal linear regression

    Klauenberg, Katy; Wübbeler, Gerd; Mickan, Bodo; Harris, Peter; Elster, Clemens

    2015-12-01

    Regression is a common task in metrology and often applied to calibrate instruments, evaluate inter-laboratory comparisons or determine fundamental constants, for example. Yet, a regression model cannot be uniquely formulated as a measurement function, and consequently the Guide to the Expression of Uncertainty in Measurement (GUM) and its supplements are not applicable directly. Bayesian inference, however, is well suited to regression tasks, and has the advantage of accounting for additional a priori information, which typically robustifies analyses. Furthermore, it is anticipated that future revisions of the GUM shall also embrace the Bayesian view. Guidance on Bayesian inference for regression tasks is largely lacking in metrology. For linear regression models with Gaussian measurement errors this tutorial gives explicit guidance. Divided into three steps, the tutorial first illustrates how a priori knowledge, which is available from previous experiments, can be translated into prior distributions from a specific class. These prior distributions have the advantage of yielding analytical, closed form results, thus avoiding the need to apply numerical methods such as Markov Chain Monte Carlo. Secondly, formulas for the posterior results are given, explained and illustrated, and software implementations are provided. In the third step, Bayesian tools are used to assess the assumptions behind the suggested approach. These three steps (prior elicitation, posterior calculation, and robustness to prior uncertainty and model adequacy) are critical to Bayesian inference. The general guidance given here for Normal linear regression tasks is accompanied by a simple, but real-world, metrological example. The calibration of a flow device serves as a running example and illustrates the three steps. It is shown that prior knowledge from previous calibrations of the same sonic nozzle enables robust predictions even for extrapolations.

    In this tutorial the main concepts and applications of experimental design in chemistry will be explained. Unfortunately, nowadays experimental design is not as known and applied as it should be, and many papers can be found in which the "optimization" of a procedure is performed one variable at a time. Goal of this paper is to show the real advantages in terms of reduced experimental effort and of increased quality of information that can be obtained if this approach is followed. To do that, three real examples will be shown. Rather than on the mathematical aspects, this paper will focus on the mental attitude required by experimental design. The readers being interested to deepen their knowledge of the mathematical and algorithmical part can find very good books and tutorials in the references [G.E.P. Box, W.G. Hunter, J.S.

    The ATLAS Collaboratory Project at the University of Michigan has been a leader in the area of collaborative tools since 1999. Its activities include the development of standards, software and hardware tools for lecture archiving, and making recommendations for videoconferencing and remote teaching facilities. Starting in 2006 our group became involved in classroom recordings, and in early 2008 we spawned CARMA, a University-wide recording service. This service uses a new portable recording system that we developed. Capture, archiving and dissemination of rich multimedia content from lectures, tutorials and classes are increasingly widespread activities among universities and research institutes. A growing array of related commercial and open source technologies is becoming available, with several new products introduced in the last couple years. As the result of a new close partnership between U-M and CERN IT, a market survey of these products was conducted and a summary of the results are presented here. It is informing an ambitious effort in 2009 to equip many CERN rooms with automated lecture archiving systems, on a much larger scale than before. This new technology is being integrated with CERN's existing webcast, CDS, and Indico applications.

    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.

    NASA Astrophysics Data System (ADS)

    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.

  1. Basic Radar Altimetry Toolbox and Tutorial

    NASA Astrophysics Data System (ADS)

    Rosmorduc, Vinca; Niejmeier, Sander; Bronner, Emilie; Benveniste, Jérôme

    The Basic Radar Altimetry Toolbox is an "all-altimeter" collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data, including the next mission to be launched, CryoSat. It has been available from April 2007, and had been demonstrated during training courses and scientific meetings. About 900 people downloaded it (January 2009), with many "newcomers" to altimetry among them. Users' feedbacks, developments in altimetry, and practice, showed that new interesting features could be added. Some have been added and/or improved in version 2. Others are ongoing, some are in discussion. The Basic Radar Altimetry Toolbox is able: • to read most distributed radar altimetry data, from ERS-1 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, Jason-2, and the furure CryoSat and Saral missions, • to perform some processing, data editing and statistic, • and to visualize the results. It can be used at several levels/several ways: • as a data reading tool, with APIs for C, Fortran, Matlab and IDL • as processing/extraction routines, through the on-line command mode • as an educational and a quick-look tool, with the graphical user interface As part of the Toolbox, a Radar Altimetry Tutorial gives general information about altimetry, the technique involved and its applications, as well as an overview of past, present and future missions, including information on how to access data and additional software and documen-tation. It also presents a series of data use cases, covering all uses of altimetry over ocean, cryosphere and land, showing the basic methods for some of the most frequent manners of using altimetry data. Version 2 has been released in April 2009, including, among other improvements, a Mac OS X version, RiverLake data reading capability, full waveform processing and plotting, new plotting capabilities, export in GeoTiff, including a Google Earth export feature, easier export in Ascii, a rethinking of the Graphical

    2014-08-15

    Gas discharge plasmas formed at atmospheric pressure and near room temperature have recently been shown to be potentially useful for surface and wound sterilization, antisepsis, bleeding cessation, wound healing, and cancer treatment, among other biomedical applications. This tutorial review summarizes the field, stressing the likely role of reactive oxygen and nitrogen species created in these plasmas as the biologically and therapeutically active agents. Reactive species, including radicals and non-radical compounds, are generated naturally within the body and are now understood to be essential for normal biological functions. These species are known to be active agents in existing therapies for wound healing, infection control, and cancer treatment. But they are also observed at elevated levels in persons with many diseases and are associated with aging. The physical and chemical complexity of plasma medical devices and their associated biochemical effects makes the development of safe, effective plasma medical devices and procedures a challenge, but encouragingly rapid progress has been reported around the world in the last several years.

  5. Mass spectrometry in food proteomics: a tutorial.

    PubMed

    Cunsolo, Vincenzo; Muccilli, Vera; Saletti, Rosaria; Foti, Salvatore

    2014-09-01

    In the last decades, the continuous and rapid evolution of proteomic approaches has provided an efficient platform for the characterization of food-derived proteins. Particularly, the impressive increasing in performance and versatility of the MS instrumentation has contributed to the development of new analytical strategies for proteins, evidencing how MS arguably represents an indispensable tool in food proteomics. Investigation of protein composition in foodstuffs is helpful for understanding the relationship between the protein content and the nutritional and technological properties of foods, the production of methods for food traceability, the assessment of food quality and safety, including the detection of allergens and microbial contaminants in foods, or even the characterization of genetically modified products. Given the high variety of the food-derived proteins and considering their differences in chemical and physical properties, a single proteomic strategy for all purposes does not exist. Rather, proteomic approaches need to be adapted to each analytical problem, and development of new strategies is necessary in order to obtain always the best results. In this tutorial, the most relevant aspects of MS-based methodologies in food proteomics will be examined, and their advantages and drawbacks will be discussed. PMID:25230173

  6. Validation of chemometric models - a tutorial.

    PubMed

    Westad, Frank; Marini, Federico

    2015-09-17

    In this tutorial, we focus on validation both from a numerical and conceptual point of view. The often applied reported procedure in the literature of (repeatedly) dividing a dataset randomly into a calibration and test set must be applied with care. It can only be justified when there is no systematic stratification of the objects that will affect the validated estimates or figures of merits such as RMSE or R(2). The various levels of validation may, typically, be repeatability, reproducibility, and instrument and raw material variation. Examples of how one data set can be validated across this background information illustrate that it will affect the figures of merits as well as the dimensionality of the models. Even more important is the robustness of the models for predicting future samples. Another aspect that is brought to attention is validation in terms of the overall conclusions when observing a specific system. One example is to apply several methods for finding the significant variables and see if there is a consensus subset that also matches what is reported in the literature or based on the underlying chemistry.

  7. TUTORIAL: Electrical resistance: an atomistic view

    NASA Astrophysics Data System (ADS)

    Datta, Supriyo

    2004-07-01

    This tutorial article presents a 'bottom-up' view of electrical resistance starting from something really small, like a molecule, and then discussing the issues that arise as we move to bigger conductors. Remarkably, no serious quantum mechanics is needed to understand electrical conduction through something really small, except for unusual things like the Kondo effect that are seen only for a special range of parameters. This article starts with energy level diagrams (section 2), shows that the broadening that accompanies coupling limits the conductance to a maximum of q2/h per level (sections 3, 4), describes how a change in the shape of the self-consistent potential profile can turn a symmetric current-voltage characteristic into a rectifying one (sections 5, 6), shows that many interesting effects in molecular electronics can be understood in terms of a simple model (section 7), introduces the non-equilibrium Green function (NEGF) formalism as a sophisticated version of this simple model with ordinary numbers replaced by appropriate matrices (section 8) and ends with a personal view of unsolved problems in the field of nanoscale electron transport (section 9). Appendix A discusses the Coulomb blockade regime of transport, while appendix B presents a formal derivation of the NEGF equations. MATLAB codes for numerical examples are listed in appendix C. (The appendices are available in the online version only.)

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.

    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.

  13. Development of cross-platform computer-based tutorials.

    1996-11-01

    The development, distribution, and support of computer-based instruction in radiology is complicated by the fact that many radiology departments use computers with different operating systems: Macintosh and Windows. A program for developing cross-platform on-line documentation was adapted to develop a graphical hypertext tutorial that would run identically on both types of computers. A tutorial for interpreting ventilation-perfusion scans was created that would run on the Windows platform. The graphics were converted to Macintosh format, and the identical source information was recompiled to run on the Macintosh platform. It was found that the tutorial, with its hypertext, full-color graphics, graphical links, searching, user annotation, and bookmarks, could be displayed and operated identically between platforms. Cross-platform tutorials must be developed on a Windows-based computer but require only one source file for both Windows-based and Macintosh computers. These tutorials can be distributed free of charge, and minimal training is required for those who already know how to use Windows on-line help. PMID:8946549

  14. A tutorial on the principles of harmonic intonation for trombonists

    NASA Astrophysics Data System (ADS)

    Keener, Michael Kenneth

    A Tutorial on the Principles of Harmonic Intonation for Trombonists includes a manual containing background information, explanations of the principles of harmonic intonation, and printed musical examples for use in learning and practicing the concepts of harmonic intonation. An audio compact disk containing music files corresponding to the printed music completes the set. This tutorial is designed to allow performing musicians and students to practice intonation skills with the pitch-controlled music on the compact disc. The music on the CD was recorded in movable-comma just intonation, replicating performance parameters of wind, string, and vocal ensembles. The compact disc includes sixty tracks of ear-training exercises and interval studies with which to practice intonation perception and adjustment. Tuning notes and examples of equal-tempered intervals and just intervals are included on the CD. The intonation exercises consist of musical major scales, duets, trios, and quartet phrases to be referenced while playing the printed music. The CD tracks allow the performer to play scales in unison (or practice other harmonic intervals) or the missing part of the corresponding duet, trio, or quartet exercise. Instructions in the manual guide the user through a process that can help prepare musicians for more accurate musical ensemble performance. The contextual essay that accompanies the tutorial includes a description of the tutorial, a review of related literature, methodology of construction of the tutorial, evaluations and outcomes, conclusions and recommendations for further research, and a selected bibliography.

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

    2008-04-01

    We present results from a comparative study of student understanding for students who attended recitation classes that used different teaching methods. The purpose of the study was to evaluate which teaching methods would be the most effective for recitation classes associated with large lectures in introductory physics courses. Student volunteers from our introductory calculus-based physics course at the University of Cincinnati attended a special recitation class that was taught using one of four different teaching methods. A total of 272 students were divided into approximately equal groups for each method. Students in each class were taught the same topic, ``Changes in Energy and Momentum,'' from ``Tutorials in Introductory Physics'' by Lillian McDermott, Peter Shaffer and the Physics Education Group at the University of Washington. The different teaching methods varied in the amount of student and teacher engagement. Student understanding was evaluated through pretests and posttests. Our results demonstrate the importance of the instructor's role in teaching recitation classes. The most effective teaching method was for students working in cooperative learning groups with the instructors questioning the groups using Socratic dialogue. In addition, we investigated student preferences of modes of instruction through an open-ended survey. Our results provide guidance and evidence for the teaching methods which should be emphasized in training course instructors.

  9. Lectures on Geophysical Fluid Dynamics

    NASA Astrophysics Data System (ADS)

    Samelson, Roger M.

    The fluid kaleidoscope of the Earth's ocean and atmosphere churns and sparkles with jets, gyres, eddies, waves, streams, and cyclones. These vast circulations, essential elements of the physical environment that support human life, are given a special character by the Earth's rotation and by their confinement to a shallow surficial layer, thin relative to the solid Earth in roughly the same proportion as an apple skin is to an apple. Geophysical fluid dynamics exploits this special character to develop a unified theoretical approach to the physics of the ocean and atmosphere.With Lectures on Geophysical Fluid Dynamics, Rick Salmon has added an insightful and provocative volume to the handful of authoritative texts currently available on the subject. The book is intended for first-year graduate students, but advanced students and researchers also will find it useful. It is divided into seven chapters, the first four of these adapted from course lectures. The book is well written and presents a fresh and stimulating perspective that complements existing texts. It would serve equally well either as the main text for a core graduate curriculum or as a supplementary resource for students and teachers seeking new approaches to both classical and contemporary problems. A lively set of footnotes contains many references to very recent work. The printing is attractive, the binding is of high quality, and typographical errors are few.

  10. Effectiveness of Tutorials for Introductory Physics in Argentinean high schools

    Benegas, J.; Flores, J. Sirur

    2014-06-01

    This longitudinal study reports the results of a replication of Tutorials in Introductory Physics in high schools of a Latin-American country. The main objective of this study was to examine the suitability of Tutorials for local science education reform. Conceptual learning of simple resistive electric circuits was determined by the application of the single-response multiple-choice test "Determining and Interpreting Resistive Electric Circuits Concepts Test" (DIRECT) to high school classes taught with Tutorials and traditional instruction. The study included state and privately run schools of different socioeconomic profiles, without formal laboratory space and equipment, in classes of mixed-gender and female-only students, taught by novice and experienced instructors. Results systematically show that student learning is significantly higher in the Tutorials classes compared with traditional teaching for all of the studied conditions. The results also show that long-term learning (one year after instruction) in the Tutorials classes is highly satisfactory, very similar to the performance of the samples of college students used to develop the test DIRECT. On the contrary, students following traditional instruction returned one year after instruction to the poor performance (<20%) shown before instruction, a result compatible with the very low level of conceptual knowledge of basic physics recently determined by a systematic study of first-year students attending seven universities in Spain and four Latin-American countries. Some replication and adaptation problems and difficulties of this experience are noted, as well as recommendations for successful use of Tutorials in high schools of similar educational systems.

  11. The GOCE User Toolbox (GUT) and Tutorial

    NASA Astrophysics Data System (ADS)

    2015-12-01

    The GOCE User Toolbox (GUT) is an integrated suite of tools for the analysis and use of GOCE Level 2 gravity products. GUT supports applications in geodesy, oceanography and solid earth physics. The accompanying GUT tutorial provides information and guidance on how to use the toolbox for a variety of applications within each of these domains. An important motivation for the development of GUT has been the desire that users should be able to exploit the GOCE gravity products to calculate derived products relevant to their particular domains without necessarily needing to understand the technicalities of particular geodetic concepts and algorithms. As such, GUT is also suitable for use as an aid to the teaching of geophysics. A comprehensive and up-to-date set of a-priori data and models are supplied with the toolbox, together with a range of pre-defined workflows, allowing the user to immediately calculate useful geophysical quantities. The toolbox is supported by The GUT Algorithm Description and User Guide and The GUT Install Guide. GUT is cross-platform and may be used on Windows PCs, UNIX/Linux workstations and Macs. GUT version 2.2 was released in April 2014 and, besides some bug-fixes, the capability to calculate the simple Bouguer anomaly was added. Recently, GUT version 3 has been released. Through a collaborative effort between the relevant scientific communities, this version has built on earlier releases by further extending the functionality of the toolbox within the fields of geodesy, oceanography and solid earth physics. Additions include the ability to work directly with gravity gradients, anisotropic diffusive filtering, and the computation of Bouguer and isostatic gravity anomalies. The interface between the user and the toolbox has also been greatly improved and GUT version 3 now includes an attractive and intuitive Graphical User Interface. An associated GUT VCM tool for analysing the GOCE variance covariance matrices is also available.

    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.

    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.

    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.

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

    PubMed

    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.

  16. Communicating Big Data with the Public via Tutorials

    NASA Astrophysics Data System (ADS)

    Montgomery, Michele

    2015-08-01

    Although numerical models that researchers use to analyze large astronomy data sets may be easily found on NASA websites, tutorials on how to use these models and understanding the products of the models are lacking. Thus, communication with the public is ineffective. Where the public could easily engage with data and models to determine if their work and lives could be impacted, and if so, to plan accordingly, a lack of good tutorials typically results in the public waiting for a tweet, a post on Facebook, an announcement on a NASA webpage, an alert sent via text message or email, etc. An example is a solar flare or coronal mass ejection event that may impact GPS devices, the precision of which is heavily relied upon by several sectors of the public and military. To allow the public to engage in real time with solar data and NASA developed heliophysics software, we have developed tutorials. In this work, we present our tutorials made for NASA's Living With a Star Program on the such as Integrated Space Weather Analysis (ISWA) layout and the WSA-ENLIL-CONE Model to analyze a CME Evolution that occurred in 2010. We present our results and our analysis of the public's ability to understand the model's predictions of whether the event will impact Earth. By training the public to use the data and to understand model predictions, we turn passive recipients into engaged and self-supporting users of NASA data of space weather events.

  2. Interactive Web-based tutorials for teaching digital electronics

    NASA Astrophysics Data System (ADS)

    Bailey, Donald G.

    2000-10-01

    With a wide range of student abilities in a class, it is difficult to effectively teach and stimulate all students. A series of web based tutorials was designed to help weaker students and stretch the stronger students. The tutorials consist of a series of HTML web pages with embedded Java applets. This combination is particularly powerful for providing interactive demonstrations because any textual content may be easily provided within the web page. The applet is able to be a compete working program that dynamically illustrates the concept, or provides a working environment for the student to experiment and work through their solution. The applet is dynamic, and responds to the student through both mouse clicks and keyboard entry. These allow the student to adjust parameters, make selections, and affect the way the program is run or information is displayed. Such interaction allows each applet to provide a mini demonstration or experiment to help the student understand a particular concept or technique. The approach taken is illustrated with a tutorial that dynamically shows the relationships between a truth table, Karnaugh amp, logic circuit and Boolean algebra representations of a logic function, and dramatically illustrates the effect of minimization on the resultant circuit. Use of the tutorial has resulted in significant benefits, particularly with weaker students.

  17. Engagement of students with lectures in biochemistry and pharmacology.

    PubMed

    Davis, Elizabeth Ann; Hodgson, Yvonne; Macaulay, Janet Olwyn

    2012-01-01

    Academic staff at universities have become concerned about the decrease in student attendance at lectures and the implication of this on student achievement and learning. Few studies have measured actual lecture attendance in a coherent or comprehensive way. The aim of this study was to measure actual lecture attendance of students over two year levels enrolled in two separate science disciplines, biochemistry and pharmacology. The study further sought to determine the factors that influence lecture attendance. Attendance at lectures in four units of study was monitored over a 12-week semester. Attendance at lectures decreased over the semester and was lower at early morning lectures (8 A.M.; 9 A.M.). A questionnaire surveying students about their preparation for lectures, their compensation for missed lectures and the factors influencing their nonattendance was administered at the end of the semester. Students reported that the major factors influencing their attendance at lectures related to timetable issues and the quality of lecturing. If students missed lectures, the majority read the lecture notes and listened to the online recordings. The availability of online recordings of lectures was not a major influence on attendance at lectures. In three of the four units studied there was no correlation between self-reported lecture attendance and exam performance. The results of the study indicate that universities should dedicate more resources to timetabling and to supporting staff to improve the quality of their lectures. PMID:22987551

    A conventional lecture on Laser Engineering had been done in a lecture room till 1999. A content using on-demand streaming method was made for an online lecture of Laser Engineering in 2000. The figures and equations used on the conventional lecture and the voice recorded for the online lecture were converted to the real media. Then an online lecture has been provided to students by using a Helix Universal Server. The trial of the online lecture was done only for the students who wanted to take the online lecture course in 2000. The online lectures have been recognized as the credits for graduation by the change of a law since 2001. About 100 students have registered the online lecture of Laser Engineering every year since 2001. Here, three years' questionnaire surveys of the online lecture are summarized, and results of examinations on the conventional lecture for two years and on the online lecture for three years are compared. It is recognized for the lecture of Laser Engineering that the educational effect of the online lecture is comparable to or better than that of the conventional lecture.

  5. 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.

  7. 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.

  10. Development and testing of a CD-ROM based tutorial for nursing students: getting ready for HIPAA.

    PubMed

    Feeg, Veronica D; Bashatah, Adel; Langley, Christena

    2005-08-01

    The purpose of this study was to develop and test a CD-ROM tutorial for nursing students to educate them on how the rules and regulations of the Health Insurance Portability and Accountability Act (HIPAA) affect them as they engage in patient care activities in hospitals. The project was completed in two parts, the first of which was production of a stand-alone, audio lecture, image and text self-instruction on CD-ROM to distribute to students as they began their clinical experience. The second part compared the effectiveness of learning the HIPAA content via CD-ROM to a text-directed, self study method. Students were pretested and randomly assigned to one of the types of instruction based on their seminar group assignment. One group received the CD-ROM, Getting Started with HIPAA, along with a journal article on HIPAA, while the other (control) group received only the journal article. All students were instructed to prepare for a test on their understanding about HIPAA by the end of the clinical rotation. The test was analyzed, and items clarified to yield a reliable Web-based examination with 20 questions, 18 of which were used in the analysis. The students' scores were analyzed before and after the instruction, and the methods of instruction were compared. The study findings demonstrated significant differences between experimental-group and control-group students' performance on a knowledge test of HIPAA, as well as overall satisfaction with learning the material by CD-ROM among students who used it. The tutorial is now available for all students, and the Web-based examination provides automatic scoring to a preestablished competence level. PMID:16130345

  13. Online Multimedia PreLab Tutorials in Conservation Laws

    NASA Astrophysics Data System (ADS)

    Sadaghiani, Homeyra R.

    2010-10-01

    Physics laboratories are intended to provide students an opportunity to investigate physical phenomena by making observations, collecting and analyzing data, and presenting their findings clearly. However, some students lack an adequate preparation and conceptual background to achieve these objectives. To help students to better prepare for the laboratory sessions at Cal Poly Pomona, in a pilot study, we designed a 20-minute online multimedia prelab tutorial on the topics of conservation laws using flash animations, narration, and videos. This multimedia prelab includes a brief lesson on the theory, as well as an introduction to the laboratory procedure and apparatus with embedded assessment questions and feedback throughout the module. The preliminary data shows improvement in student overall preparation, quiz scores, and their lab reports after using this prelab tutorial.

    Many colleges and universities offer several levels of introductory chemistry instruction. As a result, there is often a need to provide students advice into which course or sequence they should be enrolled. This paper describes a thirty-question assessment that has been developed, tested, and used on-line. In addition, a second Internet-based feature, a set of tutorials about math and calculator skills and approaches to solving word problems has been implemented.

    Successful implementation of tutorials includes establishing norms for learning in the tutorial classroom. The teaching assistants (TAs) who lead each tutorial section are important arbiters of these norms. TAs who value (buy into) tutorials are more likely to convey their respect for the material and the tutorial process to the students, as well as learning more themselves. We present a case study of a TA who does not buy into certain aspects of the tutorials he teaches and demonstrate how his lack of buy-in affects specific classroom interactions. We would hope to design professional development programs to help TAs appreciate the power of tutorial instruction. However, our research suggests that the typical professional development activities offered to tutorial TAs are not likely to be effective. Instead, it appears that what we call the “social and environmental context” of the tutorials—including classroom, departmental, and institutional levels of implementation—has the potential to strongly affect TA buy-in to tutorials and probably outweighs the influence of any particular activity that we might prepare for them.

    The Association for Women in Mathematics (AWM) in cooperation with the Society for Industrial and Applied Mathematics (SIAM) and with funding from the Department of Energy initiated a new lecture series. The purpose of the lecture series is to increase the visibility of women who have made significant contributions in applied or computational mathematics. The AWM-SIAM Sonia Kovalevsky Lecture is presented at the SIAM Annual Meeting which is a national conference. The lecturer is a woman who has made distinguished contributions in applied or computational mathematics. The lecturer is determined by the Selection Committee which consists of two members of AWM and two members of SIAM, appointed by the presidents of these organizations. The committee may solicit nominations from other members of the scientific and engineering community. The lectureship may be awarded to any woman in the scientific or engineering community.

  4. Transient state kinetics tutorial using the kinetics simulation program, KINSIM.

    Wachsstock, D H; Pollard, T D

    1994-01-01

    This article provides an introduction to a computer tutorial on transient state kinetics. The tutorial uses our Macintosh version of the computer program, KINSIM, that calculates the time course of reactions. KINSIM is also available for other popular computers. This program allows even those investigators not mathematically inclined to evaluate the rate constants for the transitions between the intermediates in any reaction mechanism. These rate constants are one of the insights that are essential for understanding how biochemical processes work at the molecular level. The approach is applicable not only to enzyme reactions but also to any other type of process of interest to biophysicists, cell biologists, and molecular biologists in which concentrations change with time. In principle, the same methods could be used to characterize time-dependent, large-scale processes in ecology and evolution. Completion of the tutorial takes students 6-10 h. This investment is rewarded by a deep understanding of the principles of chemical kinetics and familiarity with the tools of kinetics simulation as an approach to solve everyday problems in the laboratory.

  5. Electronic voting to encourage interactive lectures: a randomised trial

    PubMed Central

    2007-01-01

    Background Electronic Voting Systems have been used for education in a variety of disciplines. Outcomes from these studies have been mixed. Because results from these studies have been mixed, we examined whether an EVS system could enhance a lecture's effect on educational outcomes. Methods A cohort of 127 Year 5 medical students at the University of Adelaide was stratified by gender, residency status and academic record then randomised into 2 groups of 64 and 63 students. Each group received consecutive 40-minute lectures on two clinical topics. One group received the EVS for both topics. The other group received traditional teaching only. Evaluation was undertaken with two, 15-question multiple-choice questionnaires (MCQ) assessing knowledge and problem solving and undertaken as a written paper immediately before and after the lectures and repeated online 8–12 weeks later. Standardised institutional student questionnaires were completed for each lecture and independent observers assessed student behaviour during the lectures. Lecturer's opinions were assessed by a questionnaire developed for this study. Results Two-thirds of students randomised to EVS and 59% of students randomised to traditional lectures attended. One-half of the students in the EVS group and 41% in the traditional group completed all questionnaires. There was no difference in MCQ scores between EVS and traditional lectures (p = 0.785). The cervical cancer lectures showed higher student ranking in favour of EVS in all parameters. The breast cancer lectures showed higher ranking in favour of traditional lectures in 5 of 7 parameters (p < 0.001). The observed higher-order lecturer-students interactions were increased in the EVS lecture for one lecturer and reduced for the other. Both lecturers felt that the EVS lectures were difficult to prepare, that they were able to keep to time in the traditional lectures, that the educational value of both lecture styles was similar, and that they were

  6. Explicit constructivism: a missing link in ineffective lectures?

    Prakash, E S

    2010-06-01

    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.

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

    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.

  8. Interactive lectures: Clickers or personal devices?

    PubMed

    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.

  10. The newly-found Rheticus lectures.

    NASA Astrophysics Data System (ADS)

    Kraai, J.

    This article discusses a hitherto unknown set of lectures presumably given by Georg Joachim Rheticus, and taken down by several students in Wittenberg. These lectures offer considerable insight into Rheticus' teaching activities shortly before the publication of De Revolutionibus (1543). The most salient aspects of this newly-found text may be summarized as follows: a) Rheticus was known among the students in Wittenberg as Joachimus Heliopolitanus, i.e. Joachim of the City of the Sun - a clear reference to Rheticus' stay in Frauenburg with Copernicus, b) Rheticus returned from his stay with Copernicus to Wittenberg for a short period of time in 1540 to fulfill his professorial obligations, and c) we have 155 folio pages which document Rheticus' introductory lectures on astronomy.

  11. 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.

  12. Intrinsic deficiencies of lectures as a teaching method.

    PubMed

    Pale, Predrag

    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. PMID:23941004

  13. Revitalizing Ernst Mach's Popular Scientific Lectures

    2007-06-01

    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.

    2009-09-01

    Many large scientific projects and scientific centres incorporate some kind of outreach programme. Almost all of these outreach programmes include public scientific lectures delivered by practising scientists. In this article, we examine such lectures from the perspectives of: (i) lecturers (7) who are practising scientists acknowledged to be good public lecturers and (ii) audiences composed of high-school students (169) and high-school physics teachers (80) who attended these lectures. We identify and discuss the main goals as expressed by the lecturers and the audiences, and the correspondence between these goals. We also discuss how the lecturers' goals impact on the design of their lectures and examine how the lecture affects audiences with different attitudes towards (and interests in) physics. Our findings suggest that the goals of the participating lecturers and the expectations of their audiences were highly congruent. Both believe that a good public scientific lecture must successfully communicate state-of-the-art scientific knowledge to the public, while inspiring interest in and appreciation of science. Our findings also suggest that exemplary public scientific lectures incorporate content, structure and explanatory means that explicitly adhere to the lecturers' goals. We identify and list several design principles.

  18. A web-based tutorial for ultrasonic attenuation measurement

    NASA Astrophysics Data System (ADS)

    Margetan, Frank J.; Barnard, Dan; Orman, David; Feygin, Alex; Pavel, Brittney

    2014-02-01

    An ultrasonic attenuation-versus-frequency curve can serve as an "ultrasonic signature" which may be correlated with microstructural properties of interest such as grain size in metals or porosity level in composites. Attenuation also plays a role in ultrasonic inspections and is consequently a key input into many inspection simulation models. A web-based self-tutorial on practical attenuation measurements is under development. The focus is on pulse/echo immersion measurements made using a broadband transducer to deduce attenuation within the transducer's useable bandwidth. Two approaches are considered: one using a calibration specimen having a known attenuation curve, and one without. In the first approach a back-wall (BW) echo in the calibration specimen is compared with a BW echo in the test specimen. In the second approach various BW reverberation echoes in the test specimen are compared with one another or with a front-wall echo. The web-based tutorial incorporates three classes of materials. The first includes written documentation and videos describing the measurement setups, the data-acquisition and analysis procedures, and the underlying models use to analyze the raw UT data. Secondly, general purpose "stand-alone" data-analysis software is supplied that is designed to be used with any ultrasonic inspection system that can output A-scan data as a text file. This includes both FORTRAN software and Excel spreadsheet calculators that accept A-scan text data as inputs. Thirdly, we supply demonstration software where the data acquisition and analysis procedures are integrated with a specific class of commercial ultrasonic test instruments, namely those running UTEX Winpect control software. This paper provides an overview of the measurement methods and tutorial materials. We also present early results from round-robin trials in which selected metal and composite specimens are being sent to participating partners for attenuation measurement.

  19. Spreadsheet for designing valid least-squares calibrations: A tutorial.

    PubMed

    Bettencourt da Silva, Ricardo J N

    2016-02-01

    Instrumental methods of analysis are used to define the price of goods, the compliance of products with a regulation, or the outcome of fundamental or applied research. These methods can only play their role properly if reported information is objective and their quality is fit for the intended use. If measurement results are reported with an adequately small measurement uncertainty both of these goals are achieved. The evaluation of the measurement uncertainty can be performed by the bottom-up approach, that involves a detailed description of the measurement process, or using a pragmatic top-down approach that quantify major uncertainty components from global performance data. The bottom-up approach is not so frequently used due to the need to master the quantification of individual components responsible for random and systematic effects that affect measurement results. This work presents a tutorial that can be easily used by non-experts in the accurate evaluation of the measurement uncertainty of instrumental methods of analysis calibrated using least-squares regressions. The tutorial includes the definition of the calibration interval, the assessments of instrumental response homoscedasticity, the definition of calibrators preparation procedure required for least-squares regression model application, the assessment of instrumental response linearity and the evaluation of measurement uncertainty. The developed measurement model is only applicable in calibration ranges where signal precision is constant. A MS-Excel file is made available to allow the easy application of the tutorial. This tool can be useful for cases where top-down approaches cannot produce results with adequately low measurement uncertainty. An example of the application of this tool to the determination of nitrate in water by ion chromatography is presented. PMID:26653439

    This informal tutorial is intended for investigators and students who would like to understand the workings of information retrieval systems, including the most frequently used search engines: PubMed and Google. Having a basic knowledge of the terms and concepts of information retrieval should improve the efficiency and productivity of searches. As well, this knowledge is needed in order to follow current research efforts in biomedical information retrieval and text mining that are developing new systems not only for finding documents on a given topic, but extracting and integrating knowledge across documents.

    Alkauskas, Audrius; McCluskey, Matthew D.; Van de Walle, Chris G.

    2016-05-01

    Point defects affect or even completely determine physical and chemical properties of semiconductors. Characterization of point defects based on experimental techniques alone is often inconclusive. In such cases, the combination of experiment and theory is crucial to gain understanding of the system studied. In this tutorial, we explain how and when such comparison provides new understanding of the defect physics. More specifically, we focus on processes that can be analyzed or understood in terms of configuration coordinate diagrams of defects in their different charge states. These processes include light absorption, luminescence, and nonradiative capture of charge carriers. Recent theoretical developments to describe these processes are reviewed.

    The design of low-velocity superconducting structures has been an active area of the superconducting rf (srf) technology for more than 3 decades. More recently, with the growing interest in medium-energy ion and proton accelerators, a sustained world-wide effort has been directed toward the development of the superconducting structures for the intermediate velocity region. In this tutorial we address the design issues that are specific to low- and medium-velocity superconducting cavities. Simple electrostatic and electrodynamic models based on transmission lines are presented, and scaling laws are derived.

  4. 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

    It is often assumed that engaging in a one-on-one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested…

  7. Auditory brainstem response to complex sounds: a tutorial

    PubMed Central

    Skoe, Erika; Kraus, Nina

    2010-01-01

    This tutorial provides a comprehensive overview of the methodological approach to collecting and analyzing auditory brainstem responses to complex sounds (cABRs). cABRs provide a window into how behaviorally relevant sounds such as speech and music are processed in the brain. Because temporal and spectral characteristics of sounds are preserved in this subcortical response, cABRs can be used to assess specific impairments and enhancements in auditory processing. Notably, subcortical function is neither passive nor hardwired but dynamically interacts with higher-level cognitive processes to refine how sounds are transcribed into neural code. This experience-dependent plasticity, which can occur on a number of time scales (e.g., life-long experience with speech or music, short-term auditory training, online auditory processing), helps shape sensory perception. Thus, by being an objective and non-invasive means for examining cognitive function and experience-dependent processes in sensory activity, cABRs have considerable utility in the study of populations where auditory function is of interest (e.g., auditory experts such as musicians, persons with hearing loss, auditory processing and language disorders). This tutorial is intended for clinicians and researchers seeking to integrate cABRs into their clinical and/or research programs. PMID:20084007

    Stankovski, Tomislav; Duggento, Andrea; McClintock, Peter V. E.; Stefanovska, Aneta

    2014-12-01

    In view of the current availability and variety of measured data, there is an increasing demand for powerful signal processing tools that can cope successfully with the associated problems that often arise when data are being analysed. In practice many of the data-generating systems are not only time-variable, but also influenced by neighbouring systems and subject to random fluctuations (noise) from their environments. To encompass problems of this kind, we present a tutorial about the dynamical Bayesian inference of time-evolving coupled systems in the presence of noise. It includes the necessary theoretical description and the algorithms for its implementation. For general programming purposes, a pseudocode description is also given. Examples based on coupled phase and limit-cycle oscillators illustrate the salient features of phase dynamics inference. State domain inference is illustrated with an example of coupled chaotic oscillators. The applicability of the latter example to secure communications based on the modulation of coupling functions is outlined. MatLab codes for implementation of the method, as well as for the explicit examples, accompany the tutorial.

    Analytical procedures are routinely used for structural integrity of buildings, but for moisture control, designers still rely on rules of thumb, such as install vapor retarders in cold climates on the inside and in warm climates on the exterior of thermal insulation. However, cold and warm climates are ill defined, large areas of the United States have warm summers and cold winters, and the rules do not recognize the effects of other materials in the thermal envelope. Analytical methods for determining the moisture movement in building envelopes are available. These methods can predict condensation, moisture content of layers and surface relative humidities; dynamic methods also predict the duration of moisture excursions, providing a basis for moisture damage risk assessment. Recognizing that practitioners are not generally trained to use available analytical tools, the Building Environment and Thermal Envelop Council (BETEC) has developed a tutorial on moisture analysis for building designers. The tutorial consists of a Moisture Primer, an Overview of Analysis Methods, and a training session on MOIST, a dynamic model developed by the National Institute for Standards and Technology. The paper outlines the need for the analytical approach to moisture control and summarizes the three sessions.

  10. Multiple tutorial-based assessments: a generalizability study

    PubMed Central

    2014-01-01

    Background Tutorial-based assessment commonly used in problem-based learning (PBL) is thought to provide information about students which is different from that gathered with traditional assessment strategies such as multiple-choice questions or short-answer questions. Although multiple-observations within units in an undergraduate medical education curriculum foster more reliable scores, that evaluation design is not always practically feasible. Thus, this study investigated the overall reliability of a tutorial-based program of assessment, namely the Tutotest-Lite. Methods More specifically, scores from multiple units were used to profile clinical domains for the first two years of a system-based PBL curriculum. Results G-Study analysis revealed an acceptable level of generalizability, with g-coefficients of 0.84 and 0.83 for Years 1 and 2, respectively. Interestingly, D-Studies suggested that as few as five observations over one year would yield sufficiently reliable scores. Conclusions Overall, the results from this study support the use of the Tutotest-Lite to judge clinical domains over different PBL units. PMID:24528493

  12. 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.

  13. Lectures series in computational fluid dynamics

    NASA Technical Reports Server (NTRS)

    Thompson, Kevin W.

    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.

    SciTech Connect

    Butcher, R.R.

    1980-01-01

    The topic of this lecture is pulse forming networks. The first item of discussion will be transmission lines because they are so prevalent, even if only in the form of coaxial cable. From there the subject will proceed to pulse-forming networks: the practical problems encountered with them, their advantages, and disadvantages. Capacitors will be our final topic, as they are the limiting factor in lumped transmission elements.

    2012-01-01

    Graphic display of clinical data is a useful tool for the behavior-analytic clinician. However, graphs can sometimes be difficult to create. We describe how to access and use an online interactive tutorial that teaches the user to create a variety of graphs often used by behavior analysts. Three tutorials are provided that cover the basics of Microsoft Excel 2007 or 2010, creating graphs for clinical purposes, and creating graphs for research purposes. The uses for this interactive tutorial and other similar programs are discussed. PMID:23326629

  19. Exploring how nurse lecturers maintain clinical credibility.

    PubMed

    Fisher, Melanie T

    2005-01-01

    The role of the nurse lecturer is changing. There is growing pressure from the government and professionals alike to recruit nurse teachers who posses both practical and recent experience of nursing [Department of Health, 1999. Making a Difference: Strengthening the Nursing, Midwifery and Health Visiting Contribution to Health and Health Care. DOH, London; UKCC, 2000. Standards for the Preparation of Teachers of Nursing, Midwifery and Health Visiting. UKCC, London]. Whilst much of the literature available suggests a growing concern amongst practitioners, students and nurse educationalists themselves about the importance of being ;clinically credible', what is not clear is how tangible it is to maintain currency and clinical credibility. In addition, the term ;clinical credibility' is in itself ill-defined. An exploratory study was undertaken within one higher education institution which sought to seek the views of nurse lecturers. The principles of ethnography were applied to this research. The sample included six of the most recently appointed nurse lecturers within one academic faculty who taught predominantly on pre-registration programmes. Data from individual and focus group interviews was analysed using a thematic content analysis approach. The findings are discussed which embrace the concepts of: working ;hands on' in the clinical area, clinical currency, transferability of skills, clinical visibility and role development. Recommendations for the development of professional practice are offered. PMID:19038175

  20. The (Embodied) Performance of Physics Concepts in Lectures

    NASA Astrophysics Data System (ADS)

    Hwang, Sungwon; Roth, Wolff-Michael

    2011-08-01

    Lectures are often thought of in terms of information transfer: students (do not) "get" or "construct meaning of" what physics professors (lecturers) say and the notes they put on the chalkboard (overhead). But this information transfer view does not explain, for example, why students have a clear sense of understanding while they sit in a lecture and their subsequent experiences of failure to understand their own lecture notes or textbooks while preparing for an exam. Based on a decade of studies on the embodied nature of science lectures, the purpose of this article is to articulate and exemplify a different way of understanding physics lectures. We exhibit how there is more to lectures than the talk plus notes. This informational "more" may explain (part of) the gap between students' participative understanding that exists in the situation where they sit in the lecture on the one hand and the one where they study for an exam from their lecture notes on the other. Our results suggest that in lectures, concepts are heterogeneous performances in which meaning is synonymous with the synergistic and irreducible transactions of many different communicative modes, including gestures, body movements, body positions, prosody, and so forth.

    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

  3. Performance of speech-language pathology students in problem-based learning tutorials and in clinical practice.

    PubMed

    Ho, Diana W L; Whitehill, Tara L; Ciocca, Valter

    2014-01-01

    The purpose of the study was to identify if performance of speech-language pathology students in problem-based learning (PBL) tutorials could predict subsequent clinical performance evaluated through (a) a non-standardized, custom clinical evaluation form (HKU form) and (b) a standardized competency assessment for speech pathology developed in Australia (COMPASS®). Students' scores from PBL tutorial performance were correlated with scores in clinical placement on both the HKU form and the COMPASS. Significant correlations were found between students' PBL tutorial performance (reflective journals and participation in the tutorial process) and their clinical performance (treatment and interpersonal skills) on the HKU clinical evaluation form. Significant correlations were also found between (a) PBL tutorial performance (participation in the tutorial process) and their clinical performance (all generic and occupational competencies, and the overall score) on the COMPASS, (b) PBL tutorial performance (reading forms) and two occupational competencies on the COMPASS, (c) PBL tutorial performance (reflective journals) and four occupational competencies and the overall score on the COMPASS. The results highlighted the need for validating the assessment for the learning process in PBL tutorials with empirical evidence and the advantage of assessing clinical performance through COMPASS in Hong Kong. Tutors, clinical supervisors and students should be given clear behavioral descriptors for expected performance in PBL tutorials and clinical practice at different year levels. PMID:23889172

    Michael, Jack

    2003-11-01

    B. F. Skinner's Science and Human Behavior (1953) became the main source of my understanding of behavior during my first semester as a college professor in 1955 at Kansas University. It has continued to exert a major influence throughout my career as the basis for a completely deterministic science of behavior, as a handbook to be consulted as a first step in dealing with any issue in behavior analysis, and as a tutorial in behavioral interpretive analysis--in the use of a small number of behavioral concepts and principles to understand behavior of all degrees of complexity. I describe four general interpretive orientations or maxims that are of broad significance for behavior analysis, and also two underappreciated major theoretical contributions. PMID:14964712

    PubMed Central

    Amorim, Leila DAF; Cai, Jianwen

    2015-01-01

    In many biomedical studies, the event of interest can occur more than once in a participant. These events are termed recurrent events. However, the majority of analyses focus only on time to the first event, ignoring the subsequent events. Several statistical models have been proposed for analysing multiple events. In this paper we explore and illustrate several modelling techniques for analysis of recurrent time-to-event data, including conditional models for multivariate survival data (AG, PWP-TT and PWP-GT), marginal means/rates models, frailty and multi-state models. We also provide a tutorial for analysing such type of data, with three widely used statistical software programmes. Different approaches and software are illustrated using data from a bladder cancer project and from a study on lower respiratory tract infection in children in Brazil. Finally, we make recommendations for modelling strategy selection for analysis of recurrent event data. PMID:25501468

  6. Tutorial on Reed-Solomon error correction coding

    NASA Technical Reports Server (NTRS)

    Geisel, William A.

    1990-01-01

    This tutorial attempts to provide a frank, step-by-step approach to Reed-Solomon (RS) error correction coding. RS encoding and RS decoding both with and without erasing code symbols are emphasized. There is no need to present rigorous proofs and extreme mathematical detail. Rather, the simple concepts of groups and fields, specifically Galois fields, are presented with a minimum of complexity. Before RS codes are presented, other block codes are presented as a technical introduction into coding. A primitive (15, 9) RS coding example is then completely developed from start to finish, demonstrating the encoding and decoding calculations and a derivation of the famous error-locator polynomial. The objective is to present practical information about Reed-Solomon coding in a manner such that it can be easily understood.

    Space Telecommunications Radio System (STRS) Architecture Standard provides a NASA standard for software-defined radio. STRS is being demonstrated in the Space Communications and Navigation (SCaN) Testbed formerly known as Communications, Navigation and Networking Configurable Testbed (CoNNeCT). Ground station radios communicating the SCaN testbed are also being written to comply with the STRS architecture. The STRS Architecture Tutorial Overview presents a general introduction to the STRS architecture standard developed at the NASA Glenn Research Center (GRC), addresses frequently asked questions, and clarifies methods of implementing the standard. The STRS architecture should be used as a base for many of NASA s future telecommunications technologies. The presentation will provide a basic understanding of STRS.

    2009-03-01

    Integrated genome databases--such as the UCSC, Ensembl and NCBI MapViewer databases--and their associated data querying and visualization interfaces (e.g. the genome browsers) have transformed the way that molecular biologists, geneticists and bioinformaticists analyze genomic data. Nevertheless, because of the complexity of these tools, many researchers take advantage of only a fraction of their capabilities. In this tutorial, using examples from medical genetics and alternative splicing, I describe some of the biological questions that can be addressed with these techniques. I also show why doing so typically is more effective than using alternative methods and indicate some of the resources available for learning more about the advanced capabilities of these powerful tools.

    1998-10-01

    The magnetron is a ubiquitous electromagnetic device, widely used in radar and microwave oven applications. However, it is not usually a part of a general physics curriculum and many practicing physicists have only a vague notion of how it works. We are developing a set of computer-based, self-paced tutorials on particle accelerators that targets a broad audience, including undergraduate science majors and industrial technicians. The magnetron is covered in our module Motion in Electromagnetic Fields as an example of a crossed-field device. We originally expected this to be an advanced topic at the graduate student level. We were pleased to find we could give a satisfying description of how the magnetron works at an introductory level, using pictures and words, without equations. This talk will present our qualitative discussion of the magnetron, direct to you from the computer screen.

  10. Cluster analysis of movement patterns in multiarticular actions: a tutorial.

    PubMed

    Rein, Robert; Button, Chris; Davids, Keith; Summers, Jeffery

    2010-04-01

    The present paper proposes a technical analysis method for extracting information about movement patterning in studies of motor control, based on a cluster analysis of movement kinematics. In a tutorial fashion, data from three different experiments are presented to exemplify and validate the technical method. When applied to three different basketball-shooting techniques, the method clearly distinguished between the different patterns. When applied to a cyclical wrist supination-pronation task, the cluster analysis provided the same results as an analysis using the conventional discrete relative phase measure. Finally, when analyzing throwing performance constrained by distance to target, the method grouped movement patterns together according to throwing distance. In conclusion, the proposed technical method provides a valuable tool to improve understanding of coordination and control in different movement models, including multiarticular actions.

  11. A Tutorial Review on Fractal Spacetime and Fractional Calculus

    NASA Astrophysics Data System (ADS)

    He, Ji-Huan

    2014-11-01

    This tutorial review of fractal-Cantorian spacetime and fractional calculus begins with Leibniz's notation for derivative without limits which can be generalized to discontinuous media like fractal derivative and q-derivative of quantum calculus. Fractal spacetime is used to elucidate some basic properties of fractal which is the foundation of fractional calculus, and El Naschie's mass-energy equation for the dark energy. The variational iteration method is used to introduce the definition of fractional derivatives. Fractal derivative is explained geometrically and q-derivative is motivated by quantum mechanics. Some effective analytical approaches to fractional differential equations, e.g., the variational iteration method, the homotopy perturbation method, the exp-function method, the fractional complex transform, and Yang-Laplace transform, are outlined and the main solution processes are given.

    2005-01-01

    Agent-based modeling and simulation (ABMS) is a new approach to modeling systems comprised of autonomous, interacting agents. ABMS promises to have far-reaching effects on the way that businesses use computers to support decision-making and researchers use electronic laboratories to support their research. Some have gone so far as to contend that ABMS is a third way of doing science besides deductive and inductive reasoning. Computational advances have made possible a growing number of agent-based applications in a variety of fields. Applications range from modeling agent behavior in the stock market and supply chains, to predicting the spread of epidemics and the threat of bio-warfare, from modeling consumer behavior to understanding the fall of ancient civilizations, to name a few. This tutorial describes the theoretical and practical foundations of ABMS, identifies toolkits and methods for developing ABMS models, and provides some thoughts on the relationship between ABMS and traditional modeling techniques.

  14. Natural computing for mechanical systems research: A tutorial overview

    NASA Astrophysics Data System (ADS)

    Worden, Keith; Staszewski, Wieslaw J.; Hensman, James J.

    2011-01-01

    A great many computational algorithms developed over the past half-century have been motivated or suggested by biological systems or processes, the most well-known being the artificial neural networks. These algorithms are commonly grouped together under the terms soft or natural computing. A property shared by most natural computing algorithms is that they allow exploration of, or learning from, data. This property has proved extremely valuable in the solution of many diverse problems in science and engineering. The current paper is intended as a tutorial overview of the basic theory of some of the most common methods of natural computing as they are applied in the context of mechanical systems research. The application of some of the main algorithms is illustrated using case studies. The paper also attempts to give some indication as to which of the algorithms emerging now from the machine learning community are likely to be important for mechanical systems research in the future.

  15. A Tutorial on Parallel and Concurrent Programming in Haskell

    NASA Astrophysics Data System (ADS)

    Peyton Jones, Simon; Singh, Satnam

    This practical tutorial introduces the features available in Haskell for writing parallel and concurrent programs. We first describe how to write semi-explicit parallel programs by using annotations to express opportunities for parallelism and to help control the granularity of parallelism for effective execution on modern operating systems and processors. We then describe the mechanisms provided by Haskell for writing explicitly parallel programs with a focus on the use of software transactional memory to help share information between threads. Finally, we show how nested data parallelism can be used to write deterministically parallel programs which allows programmers to use rich data types in data parallel programs which are automatically transformed into flat data parallel versions for efficient execution on multi-core processors.

    The study investigates factors in problem-based learning tutorial groups which promote or inhibit learning. The informants were tutors and students from speech-language pathology and physiotherapy programmes. Semi-structured focus-group interviews and individual interviews were used. Results revealed three themes: Responsibility. Time and Support. Under responsibility, the delicate balance between individual and institutional responsibility and control was shown. Time included short and long-term perspectives on learning. Under support, supporting documents, activities and personnel resources were mentioned. In summary, an increased control by the program and tutors decreases student's motivation to assume responsibility for learning. Support in tutorial groups needs to adapt to student progression and to be well aligned to tutorial work to have the intended effect. A lifelong learning perspective may help students develop a meta-awareness regarding learning that could make tutorial work more meaningful. PMID:23848371

  2. Using the tutorial approach to improve physics learning from introductory to graduate level

    NASA Astrophysics Data System (ADS)

    DeVore, Seth

    In this thesis, I discuss the development and evaluation of tutorials ranging from introductory to graduate level. Tutorials were developed based upon research on student difficulties in learning relevant concepts and findings of cognitive research. Tutorials are a valuable resource when used either in-class or as a self-study tool. They strive to help students develop a robust knowledge structure of relevant topics and improve their problem solving skills. I discuss the development of a tutorial on the Lock-in amplifier (LIA) for use as both an on-ramp to ease the transition of students entering into the research lab and to improve student understanding of the operation of the LIA for those already making use of this device. The effectiveness of this tutorial was evaluated using think aloud interviews with graduate students possessing a wide range of experience with the LIA and the findings were uniformly positive. I also describe the development and evaluation of a Quantum Interactive Learning Tutorial (QuILT) that focuses on quantum key distribution using two protocols for secure key distribution. One protocol used in the first part of the QuILT is administered to students working collaboratively in class while the second protocol used in the second part of the QuILT was administered as homework. Evaluation of student understanding of the two protocols used in this QuILT shows that it was effective at improving student understanding both immediately after working on the QuILT and two months later. Finally, I discuss the development and evaluation of four web-based tutorials focusing on quantitative problem solving intended to aid introductory students in the learning of effective problem-solving heuristics while helping them learn physics concepts. Findings suggest that while these tutorials are effective when administered in one-on-one think-aloud interviews, this effectiveness is greatly diminished when students are asked to use the tutorials as a self

  3. Online Pedagogical Tutorial Tactics Optimization Using Genetic-Based Reinforcement Learning

    PubMed Central

    Lin, Hsuan-Ta; Lee, Po-Ming; Hsiao, Tzu-Chien

    2015-01-01

    Tutorial tactics are policies for an Intelligent Tutoring System (ITS) to decide the next action when there are multiple actions available. Recent research has demonstrated that when the learning contents were controlled so as to be the same, different tutorial tactics would make difference in students' learning gains. However, the Reinforcement Learning (RL) techniques that were used in previous studies to induce tutorial tactics are insufficient when encountering large problems and hence were used in offline manners. Therefore, we introduced a Genetic-Based Reinforcement Learning (GBML) approach to induce tutorial tactics in an online-learning manner without basing on any preexisting dataset. The introduced method can learn a set of rules from the environment in a manner similar to RL. It includes a genetic-based optimizer for rule discovery task by generating new rules from the old ones. This increases the scalability of a RL learner for larger problems. The results support our hypothesis about the capability of the GBML method to induce tutorial tactics. This suggests that the GBML method should be favorable in developing real-world ITS applications in the domain of tutorial tactics induction. PMID:26065018

    2015-09-01

    To determine whether cytopathology whole slide images and virtual microscopy adaptive tutorials aid learning by postgraduate trainees, we designed a randomized crossover trial to evaluate the quantitative and qualitative impact of whole slide images and virtual microscopy adaptive tutorials compared with traditional glass slide and textbook methods of learning cytopathology. Forty-three anatomical pathology registrars were recruited from Australia, New Zealand, and Malaysia. Online assessments were used to determine efficacy, whereas user experience and perceptions of efficiency were evaluated using online Likert scales and open-ended questions. Outcomes of online assessments indicated that, with respect to performance, learning with whole slide images and virtual microscopy adaptive tutorials was equivalent to using traditional methods. High-impact learning, efficiency, and equity of learning from virtual microscopy adaptive tutorials were strong themes identified in open-ended responses. Participants raised concern about the lack of z-axis capability in the cytopathology whole slide images, suggesting that delivery of z-stacked whole slide images online may be important for future educational development. In this trial, learning cytopathology with whole slide images and virtual microscopy adaptive tutorials was found to be as effective as and perceived as more efficient than learning from glass slides and textbooks. The use of whole slide images and virtual microscopy adaptive tutorials has the potential to provide equitable access to effective learning from teaching material of consistently high quality. It also has broader implications for continuing professional development and maintenance of competence and quality assurance in specialist practice. PMID:26093936

    With the virtual explosion of biomedical information, the medical educator regularly faces a quandary regarding how much to include in the medical curriculum. Opinions differ regarding how much of the available information on a particular topic should be presented in a medical school lecture. To understand better the effect of lecture information density on learning by medical students, one of the authors gave a basic clinical lecture only or clinical lectures with varying amounts of semirelated information. Tests which measured only retention of the basic material were given before lecture attendance, immediately after the lecture, and 15 days later. The results indicated that increasing the information density of a lecture reduced retention of the basic information. The memory loss apparently was due to information presented late in the lecture displacing facts learned by the students earlier in the same hour. The data suggest that lectures to medical students are more effective aids to learning when the information density is limited to a few main points that are "essential to know." PMID:6492106

    Photo Story is a free program from Microsoft that was designed to allow people to make videos from photos and add a voice narration to it. I use Photo Story to create video lectures in my online Astronomy class at Drury University in Springfield, Missouri. I take power point slides from my publisher, turn them into JPEG files, and add my voice over them to create the video lecture. Students at a distance say the lectures make them feel like they are back in the classroom. I will present several lectures.

  8. The work of lecturing in high school chemistry

    Lecturing is an important aspect of the culture of science education. Perhaps because of the negative associations constructivist educators make with lecturing, little research has been done concerning the generally invisible aspects of the (embodied, lived) work that is required. Traditional research on science lectures focuses on ideas and (mental) concepts that somehow are "gotten across"; and it is interested in identifying verbal content and visual representations science teachers provide. The purpose of this study is to explicitly describe and theorize the living work of lecturing that produces in a societal arena everything from which students can learn. We use two case studies from the chemistry lectures in a tenth-grade Singapore classroom to exemplify the central role of the performative aspects of lecturing. We articulate and exemplify assertions that (a) corporeal performances differentiate and coordinate the contents of lecturing with its pitch, rhythm, and speech volume, and thereby orient students to specific discourse features of chemistry; and (b) corporeal performances differentiate and coordinate layers of talk with prosody, gestures, and body orientation, and thereby make analogies available to students. We conclude that what is visible in lectures (e.g., scientific discourse, analogies) is always the outcome of the (generally unattended to) corporeal labor including gestures, body orientation, and prosodic features (e.g., shifts in pitch) and that this outcome | labor pair constitutes an appropriate unit of understanding lecturing as societal phenomenon.

    Much like the world described in Abbott's "Flatland", graphene is a two-dimensional object. And, as "Flatland" is "A Romance of Many Dimensions", graphene is much more than just a flat crystal. It possesses a number of unusual properties which are often unique or superior to those in other materials. In this brief lecture I would like to explain the reason for my (and many other people's) fascination with this material, and invite the reader to share some of the excitement I've experienced while researching it.

    A public lecture is an invitation to conversation, and it is also a performance. A lively conversation---especially when one person does most of the talking---requires that you have something to say. A memorable performance requires assiduous preparation. I will touch on a number of important elements: preparing the scene and eliminating barriers between you and the audience ... engaging your listeners with a narrative arc ... the uses of the minute particular ... tension and resolution, surprise and drama ... experiments and demonstrations, specimens and souvenirs ... showing yourself, and your passion.

    The lecture is devoted to the urgent problem that is to increase the quality of cytological diagnosis, by diminishing the subjectivism factor via introduction of up-to-date computer information technologies into a cytologist's practice. Its main lines from the standardization of cytological specimen preparation to the registration of a cytologist's opinion and the assessment of the specialist's work quality at the laboratories that successfully use the capacities of the current information systems are described. Information technology capabilities to improve the interpretation of the cellular composition of cytological specimens are detailed. PMID:20799410

    2002-11-01

    This is a pedagogical introduction to D-branes, addressed to graduate students in field theory and particle physics and to other beginners in string theory. I am not going to review the most recent results since there are already many good papers on web devoted to that. Instead, I will present some old techniques in some detail in order to show how some basic properties of strings and branes as the massless spectrum of string, the effective action of D-branes and their tension can be computed using QFT techniques. Also, I will present shortly the boundary state description of D-branes. The details are exposed for bosonic branes since I do not assume any previous knowledge of supersymmetry which is not a requirement for this school. However, for completeness and to provide basic notions for other lectures, I will discuss the some properties of supersymmetric branes. The present lectures were delivered at Jorge André Swieca School on Particle and Fields, 2001, Campos do Jordão, Brazil.

    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.

  19. There is more to training than lecture

    This presentation describes information that is useful in correlating on-the-job training with developing and delivering classroom training, which enhances the learning process. Greater emphasis is being placed on classroom training versus self-study in all facets of industry. The outcome is that classroom instruction is all-too-often delivered through direct lecture. This is probably the least effective method of providing quality training. Enhancements to the classroom learning environment are necessary--such as well-planned viewgraphs, flip charts, posters, mockups, videos, demonstration activities, an on-the-job training. Without this emphasis, all too often, classroom instruction is no more effective than self-study. Most classroom training lacks demonstration activities and/or on-the-job training interfaces. Remember what Confucius said: When I hear I forget, when I see I remember, when I do I understand.'' Therefore, it makes sense to involve students through demonstration activities and/or on-the-job training as an integral part of lesson design. We need to make a conscious effort to ensure trainees understand the instructions that are necessary to perform job functions. This requires, in many cases, a diversion from past practices. We must become innovative and involve the trainees in practical activities to avoid the dismal effects of the straight lecture format. 1 ref., 2 figs.

  20. Mars Observer Lecture: Mars Orbit Insertion

    NASA Technical Reports Server (NTRS)

    Dodd, Suzanne R. (Personal Name)

    1993-01-01

    The Mars Observer mission spacecraft was primarily designed for exploring Mars and the Martian environment. The Mars Observer was launched on September 25, 1992. The spacecraft was lost in the vicinity of Mars on August 21, 1993 when the spacecraft began its maneuvering sequence for Martian orbital insertion. This videotape shows a lecture by Suzanne R. Dodd, the Mission Planning Team Chief for the Mars Observer Project. Ms Dodd begins with a brief overview of the mission and the timeline from the launch to orbital insertion. Ms Dodd then reviews slides showing the trajectory of the spacecraft on its trip to Mars. Slides of the spacecraft being constructed are also shown. She then discusses the Mars orbit insertion and the events that will occur to move the spacecraft from the capture orbit into a mapping orbit. During the trip to Mars, scientists at JPL had devised a new strategy, called Power In that would allow for an earlier insertion into the mapping orbit. The talk summarizes this strategy, showing on a slide the planned transition orbits. There are shots of the Martian moon, Phobos, taken from the Viking spacecraft, as Ms Dodd explains that the trajectory will allow the orbiter to make new observations of that moon. She also explains the required steps to prepare for mapping after the spacecraft has achieved the mapping orbit around Mars. The lecture ends with a picture of Mars from the Observer on its approach to the planet.

  1. Development and Evaluation of Internet-Based Hypermedia Chemistry Tutorials

    1996-05-01

    This progress report describes the development and student use of World-Wide-Web-based prelaboratory exercises in senior-level Instrumental Analysis during the 1995 Fall semester. The laboratory preparation exercises contained hypermedia tutorials and multiple-choice questions that were intended to familiarize the students with the experiments and instrumentation before their laboratory session. The overall goal of our work is to explore ways in which computer and network technology can be applied in education to improve the cost-effectiveness and efficacy of teaching. The course material can be accessed at http://www.chem.vt.edu/chem-ed/4114/Fall1995.html. The students were instructed to read their experimental procedure and to do the relevant laboratory preparation exercise. The individual tutorial documents were primarily text that provided basic theoretical and experimental descriptions of analytical and instrumental methods. The documents included hyperlinks to basic concepts, simple schematics, and color graphics of experimental set-ups or instrumentation. We chose the World-Wide Web (WWW) as the delivery platform for this project because of the ease of developing, distributing, and modifying hypermedia material in a client-server system. The disadvantage of the WWW is that network bandwidth limits the size and sophistication of the hypermedia material. To minimize internet transfer time, the individual documents were kept short and usually contained no more than 3 or 4 inline images. After reading the tutorial the students answered several multiple-choice questions. The figure shows one example of a multiple-choice question and the response page. Clicking on the "Submit answer" button calls a *.cgi file, which contains instructions in the PERL interpretive language, that generates the response page and saves the date, time, and student's answer to a file on the server. Usage and student perception of the on-line material was evaluated from server logs and
