Please pass the cauliflower: a recipe for introducing undergraduate students to brain structure and function. (25/726)

Neurophysiology/pathophysiology content is a frequent source of anxiety for undergraduate students and their instructors. This learning module supplements traditional lecture and overhead presentations to offer a novel, nonthreatening, and entertaining introduction to neuropathology. The module is based on a ridiculous analogy between the human brain and the cauliflower. This module has been used with both underclassmen and more advanced health science undergraduate students and has produced enthusiastic student responses while deescalating both student and instructor anxiety.  (+info)

The water-tower analogy of the cardiovascular system. (26/726)

The cardiovascular system is a complex arrangement of hydraulic, yet living, components. The complexity of this system may make it difficult for students to see the "forest" instead of the "trees." To better explain the dynamics of cardiovascular function and control, an analogy has been drawn to the operation of a city water supply. In cities that use a water tower, fresh water is pumped up into the tower from a river or other source. The tower serves as a pressure reservoir for providing water to homes through a largely parallel arrangement of distribution pipes. Local homeowners control their own water usage through faucets, whereas the city maintains water pressure by monitoring the level in the tower. Key analogous points with the cardiovascular system are the heart as the city pump, the aorta as the water tower, arteries as parallel distribution pipes, and arterioles as faucets. Baroreceptor reflex control is discussed as well as such features as the capacitance role of veins, the skeletal muscle pump, and the competition between locally mediated vasodilation and sympathetically mediated vasoconstriction. Subjective student and peer evaluations have indicated that this analogy is effective in improving student comprehension of the cardiovascular system.  (+info)

Peer instruction improves performance on quizzes. (27/726)

Peer instruction is a cooperative-learning technique that promotes critical thinking, problem solving, and decision-making skills. Benson's think-pair-share and Mazur's peer-instruction techniques are simple cooperative exercises that promote student's participation in class and increase student's interaction with each other and with the instructor in a large classroom. We borrowed concepts from Benson and Mazur and applied these concepts to enhance student involvement during the respiratory component of the medical physiology class. The medical physiology class consisted of 256 first-year medical students. The peer-instruction technique was used for 10 classes. Each class of 50 min was divided into three or four short presentations of 12-20 min. Each presentation was followed by a one-question, multiple-choice quiz on the subject discussed. Questions ranged from simple recall to those testing complex intellectual activities. Students were given 1 min to think and to record their first answer. Subsequently, students were allowed 1 min to discuss their answers with their classmates and possibly correct their first response. The percentage of correct answers increased significantly (P < 0.05) after discussion for both recall and intellectual questions. These data demonstrate that pausing three to four times during a 50-min class to allow discussion of concepts enhanced the students level of understanding and ability to synthesize and integrate material.  (+info)

Student performance and perceptions of a lecture-based course compared with the same course utilizing group discussion. (28/726)

BACKGROUND AND PURPOSE: Self-directed learning is believed to be an important aspect of the reflective clinical practitioner. This study was a comparison of student learning and student perceptions of course and instructor effectiveness, course difficulty, and amount learned between the active learning and lecture sections of a course. SUBJECTS: Participants in this study were 170 physical therapist students in 3 sections of a physiology course in the first year of their professional program. METHODS: Course grades and the results of teacher-course evaluations were compared between a lecture section and an active learning section. The students in the original active learning section were reassessed 1 year later to determine their perceptions of the course. The differences were analyzed using Kruskal-Wallis and Mann-Whitney U tests. RESULTS: Course grades were higher in both active learning sections than in the lecture section. However, the students in both active learning sections perceived that they had learned less than students in the lecture section. Students' perceptions of course and instructor effectiveness were lower in the active learning sections than in the lecture section. There were no differences between the lecture and active learning sections on the students' perceptions of course difficulty. CONCLUSION AND DISCUSSION: Although they did better in the active learning environment, physical therapist students in a basic sciences course (physiology) in the first year of their professional program perceived that they had learned less in active learning courses. They also had lower perceptions of course and instructor quality.  (+info)

Prediction of student performance on the Comprehensive Osteopathic Medical Licensing Examination Level I based on admission data and course performance. (29/726)

To predict student performance on the Comprehensive Osteopathic Medical Licensing Examination (COMLEX-USA) Level 1 examination based on academic performance during the first 2 years, stepwise regression analysis of COMLEX-USA Level 1 performance with preadmission grade point averages, Medical College Admission Test scores, and academic performance was performed on the class of 2000 to develop three formulae that were then used to predict performance on COMLEX-USA Level 1 for the class of 2001. Models ranged in accuracy of predicting the pass/fail status from 95.2% (all available data) to 96.8% (first-year grades and admissions data). A predictive model for student performance on COMLEX-USA Level 1 can be developed and has a high degree of accuracy. The model with the most variables available to choose from predicts the most failures.  (+info)

Tobacco cessation, the dental profession, and the role of dental education. (30/726)

This article describes the development of a comprehensive, interdisciplinary, tobacco cessation program based on twenty years of experience at the Indiana University (IU) School of Dentistry. It reviews the relationship between tobacco use and oral health, the nature of nicotine addiction and cessation approaches involving nicotine replacement therapy. In the early 1980s, tobacco control curriculum and cessation guidelines were introduced at the IU School of Dentistry and cooperative efforts initiated with other U.S. and Canadian dental schools. During the past decade, an interdisciplinary Nicotine Dependence Program has been developed to serve outpatients receiving treatment at all hospitals on the IU Medical Center campus. It is hoped that the models described here will be of value to other dental schools developing educational curricula and tobacco control and cessation programs.  (+info)

The impact of a clinical training unit on integrated child health care in Mexico. (31/726)

This study had two aims: to describe the activities of a clinical training unit set up for the integrated management of sick children, and to evaluate the impact of the unit after its first four years of operation. The training unit was set up in the outpatient ward of a government hospital and was staffed by a paediatrician, a family medicine physician, two nurses and a nutritionist. The staff kept a computerized database for all patients seen and they were supervised once a month. During the first three years, the demand for first-time medical consultation increased by 477% for acute respiratory infections (ARI) and 134% for acute diarrhoea (AD), with an average annual increase of demand for medical care of 125%. Eighty-nine per cent of mothers who took their child for consultation and 85% of mothers who lived in the catchment area and had a deceased child received training on how to recognize alarming signs in a sick child. Fifty-eight per cent of these mothers were evaluated as being properly trained. Eighty-five per cent of primary care physicians who worked for government institutions (n = 350) and 45% of private physicians (n = 90) were also trained in the recognition and proper management of AD and ARI. ARI mortality in children under 1 year of age in the catchment area (which included about 25,000 children under 5 years of age) decreased by 43.2% in three years, while mortality in children under 5 years of age decreased by 38.8%. The corresponding figures for AD mortality reduction were 36.3% and 33.6%. In this same period, 11 clinical research protocols were written. In summary, we learned that a clinical training unit for integrated child care management was an excellent way to offer in-service training for primary health care physicians.  (+info)

Learning preferences and learning styles: a study of Wessex general practice registrars. (32/726)

BACKGROUND: Experienced trainers know that individual registrars react very differently to identical learning experiences generated during the year in practice. This divergence reflects differences in registrars' learning styles. Only one study of United Kingdom (UK) general practitioners' learning styles has been undertaken. Learning style theory predicts that matching learning preference with learning style will enhance learning. This paper researches for the first time the evidence in the setting of UK general practice. AIM: To determine, for the general practice registrars within the Wessex Region, the nature of their learning preferences and learning styles and correlations between them. DESIGN OF STUDY: A descriptive confidential postal questionnaire survey. SETTING: Fifty-seven registrars identified in the Wessex Region with a minimum experience of six months in general practice. METHOD: The questionnaire gathered demographic data (sex, age, experience in general practice, years post-registration, and postgraduate qualifications). Learning preferences were elicited using a six-point Likert scale for learning experiences. The Honey and Mumford Learning Style Questionnaire (LSQ) elicited the registrars' learning styles. A second questionnaire was sent to non-responders. RESULTS: The response rate was 74%. Registrars report that interactive learning with feedback is preferred, but more passive learning formats remain valued. A wide range of learning style scores was found. The Honey and Mumford LSQ mean scores fell within the reflector-theorist quadrant. Evidence for correlations between learning preferences and learning styles was also found, in particular for the multiple choice question and audit components of summative assessment. CONCLUSION: A wide range of registrar learning styles exists in Wessex, and initial correlations are described between learning preferences and learning styles as predicted by style theory. This work sets the stage for a shared understanding and use of learning style theory to enhance professional learning throughout a GP's career. More research is needed in this domain.  (+info)
