Effective lecture presentation skills.

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

Medical student concentration during lectures.

A simple procedure, based on a questionnaire, was used for the assessment of student concentration during lectures. Analysis of 1353 questionnaires from 12 lectures showed that student concentration rose sharply to reach a maximum in 10-15 min, and fell steadily thereafter. The data suggest that the optimum length of a lecture may be 30 instead of 60 min. This method by which student feedback is obtained may also be used to improve lecturing performance.

Comparison of a videotape instructional program with a traditional lecture series for medical student emergency medicine teaching.

An emergency medicine faculty has reported that the use of the videotape medium for presenting curricular material to medical students is both cost effective and well suited to the educational milieu of the emergency department. In order to compare the effectiveness of videotape instruction with that of a traditional lecture, groups of students received instruction in one topic by videotape and in another topic by lecture. The students' retention of material was tested by a multiple-choice examination administered ten days later. The students scored 76.1% (683 of 898 questions) on material taught by lecture and 76.2% (673 of 883 questions) on material taught by videotape (P greater than 0.7). We conclude that videotape instruction is as effective an educational tool as the traditional lecture for an emergency medicine course.

[Health education in schools for adults: by a teacher or health education lecture?].

OBJECTIVE: To compare the results of two ways of teaching the rational use of medicines to students of centres of permanent education of adults (CPEA): one taught by the normal teachers (after training by health personnel) and one through a lecture given by the health staff. DESIGN: Intervention study without randomised distribution and with a control group. SETTING: Five CPEA in an urban centre. PARTICIPANTS: 385 students and 15 CPEA teachers. INTERVENTIONS: Three groups: a) "teachers" group: consisting of students who received education on medicines in the class-room through their teachers, who had been previously trained by health personnel; b) "lecture" group: students who had received a health education lecture on medicines given by health staff; c) non-intervention group. All three groups were administered a questionnaire before and after the intervention. Both questionnaires were paired. MEASUREMENTS AND MAIN RESULTS: 248 people completed the first questionnaire and 149 the second. Significant gains in knowledge were only found in the teachers intervention group (p < 0.01; 7.8% increase in score). Dividing the students into terciles made these gains significantly greater (11.7%) in the students of the teachers group who in the first questionnaire had intermediate scores than in the students in the other groups who had intermediate scores. CONCLUSIONS: Intervention with teachers seems more effective than either a health education lecture or no intervention, especially in the improvement in knowledge of students who already had beforehand intermediate knowledge.

Longitudinal comparison of multimedia textbook instruction with a lecture in radiology education.

RATIONALE AND OBJECTIVES: The purpose of this prospective randomized study was to compare the long-term instructional effectiveness of a computer-based radiology multimedia textbook (MMTB) with that of a traditional lecture. METHODS: Volunteer faculty/fellows and residents were randomly assigned to either a computer-based MMTB group or to a lecture group. The course content for each instructional group was the same. Pretests, posttests, and 1-year long-term retention tests were administered to both groups. The same 10 questions were on all tests. The resulting data were analyzed using analysis of variance procedures available on the Statistical Analysis System. RESULTS: A comparison of the long-term instructional effectiveness of an MMTB versus a lecture showed that the MMTB computer instructional method was at least comparable in spite of the initial short-term appearance of lecture superiority. CONCLUSION: These results suggest a promising future for MMTB and other forms of computer-based education in radiologic instruction for medical students and radiologists.

Students' perceptions of seminar and lecture-based teaching in restorative dentistry.

In an era of self-directed learning, it is important to seek the views of dental students regarding their learning experience. Using an anonymous questionnaire, clinical dental students' perceptions of seminar and lecture-based teaching in restorative dentistry were sought. 116 of 136 questionnaires circulated were returned for analysis giving a response rate of 85%. Clinical seminars as opposed to lectures were, in the opinion of the students, a more effective way of learning, more relevant to self-development and more interactive. Seminar-based learning was considered to be more amenable to self-direction than formal didactic lectures. It is concluded that the students included in this study were found to prefer seminar-based learning opportunities as opposed to more traditional styles of learning, specifically, didactic lectures.

Concordance between undergraduate dental students and their lecturers in their attitudes towards difficult patients.

The 'difficult' patient syndrome is caused by an imbalance in the dentist-patient relationship which may be influenced by human, cultural and psychosocial factors. The aim of this study was to compare the concordance between undergraduate dental students and lecturers in the degree of difficulty assigned to vignettes describing 'difficult' patients and to describe the extent to which ratings are influenced by gender, place of study and experience of specific 'difficult' patients. A questionnaire with 21 patient-stereotypes identified as difficult from the specialized literature was prepared. Both students and lecturers had to determine the degree of difficulty of each stereotype on a Likert-like scale. The students selected were in the final 2 years before graduation in Santiago de Compostela (Spain) and Porto (Portugal) Dental Schools. Lecturers were selected by simple random sampling method. Both lecturers and undergraduate students found more difficulty in those patients classified as aggressive, manipulative help-rejecters or patients with invasive companions. On the other hand, drug abusers and HIV-positive patients were ranked as presenting low levels of difficulty. Our results seem to point to the need of improving undergraduate teaching and learning of specific procedures for the management of aggressive or stubborn patients and those with invasive companions.

Comparing lecture and e-learning as pedagogies for new and experienced professionals in dentistry.

OBJECTIVE: To evaluate the relative effectiveness of e-learning versus lecture learning in VDPs and trainers. DESIGN: Experimental comparison of two groups' learning retention. SETTING: VDPs and trainers from two regions were assessed by independent researchers. METHOD: One region's VDPs and trainers received e-learning; another's received a traditional one hour lecture. Retention and understanding were tested and compared. Personal preference was assessed in group interviews. RESULTS: Significantly greater retention for the trainees occurred from lecturing rather than e-learning, and for the trainers e-learning was significantly more successful than lecturing. CONCLUSIONS: Small numbers in this study preclude wide generalisation. However, the results point to the benefits of face-to-face interaction for inexperienced staff, and the benefits of the speed and manageability of e-learning for busy, more experienced staff. The need for a discussion facility to be incorporated into ICT innovations to CPD (via, for example, online 'chatrooms') is also highlighted, with the potential of greatly enhancing e-learning efficacy.

Comparison of problem-based learning and lecture format in continuing medical education on headache diagnosis and management.

The purpose of the study was to compare the impact of continuing medical education for primary care physicians in Halifax, Nova Scotia, Canada, delivered through a problem-based learning (PBL) format with that of a lecture-based format, in the clinical area of headache diagnosis and management. From January to June 1995, 38 physicians participated in three problem-based learning sessions, and 49 in a lecture-based session in the clinical area of headache. Pre- and posttest assessments of knowledge were made of each group before and immediately after the educational sessions. A second evaluation using Key Features Problems (KFP) to measure clinical reasoning was administered to both groups 3 months later. Analysis of covariance between groups on the post-test, using the pre-test result as covariate, showed significantly greater knowledge in the PBL group. Mean post-test KFP scores also were significantly higher for the PBL group. The PBL group's satisfaction with several programme dimensions was significantly higher than that of the lecture group. These results must be viewed in the context of differing amounts of exposure for the two groups. Problem-based learning in continuing medical education in the area of headache management was associated with greater knowledge acquisition and with greater improvement in clinical reasoning skills than in a lecture-based approach. Problem-based learning also was preferred by family physicians. However, the cost-benefit of this approach was questioned, since the PBL group had more exposure. Several factors limit the generalizability of this study, e.g. the impossibility of randomly composing the two experimental groups. Further research is required to determine if the results are generalizable and whether a PBL approach results in change in practice behaviour.

A randomized, controlled, single-blind trial of teaching provided by a computer-based multimedia package versus lecture.

BACKGROUND: Computer-based teaching may allow effective teaching of important psychiatric knowledge and skills. AIMS: To investigate the effectiveness and acceptability of computer-based teaching. METHOD: A single-blind, randomized, controlled study of 166 undergraduate medical students at the University of Leeds, involving an educational intervention of either a structured lecture or a computer-based teaching package (both of equal duration). RESULTS: There was no difference in knowledge between the groups at baseline or immediately after teaching. Both groups made significant gains in knowledge after teaching. Students who attended the lecture rated their subjective knowledge and skills at a statistically significantly higher level than students who had used the computers. Students who had used the computer package scored higher on an objective measure of assessment skills. Students did not perceive the computer package to be as useful as the traditional lecture format, despite finding it easy to use and recommending its use to other students. CONCLUSIONS: Medical students rate themselves subjectively as learning less from computer-based as compared with lecture-based teaching. Objective measures suggest equivalence in knowledge acquisition and significantly greater skills acquisition for computer-based teaching.

A perplexing document in the early history of Gilles de la Tourette Syndrome: Melotti's rendition of a "Lecture of Charcot" (including a complete translation from the Italian with commentary).

In 1885, Dr. Guilio Melotti published an Italian translation of a lecture on "Convulsive Tics with Coprolalia and Echolalia" given by Jean-Martin Charcot. Although this lecture often has been cited as an authoritative statement of Charcot's view, until now it has not been translated into English. The lecture presents a number of statements that appear nowhere else in Charcot's published corpus, including some that seem to contradict Charcot's other pronouncements on maladie des tics. Although the Melotti-Charcot lecture may portray Charcot's position accurately in many passages, the article most likely is a compilation from a variety of sources.

Assessment of the quality of interaction in distance learning programmes utilizing the Internet or interactive television: perceptions of students and lecturers.

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

A model for the improvement of medical faculty lecturing.

The development of a program designed to improve the teaching effectiveness of faculty members of a new Introductory Psychopathology course at the University of Washington School of Medicine is described. Two consultants from the Office of Research in Medical Education worked closely with the faculty in designing the evaluation program during the preparation of the course. The literature on lecture effectiveness is reviewed, as are existing instructional evaluation instruments. The integration of this information and the needs of the involved faculty produced a lecture observation schedule designed to facilitate the observation of a lecture and the immediate feedback which followed each of the 15 lectures evaluated. The process of using this instrument to assist the faculty in self-improvement is discussed. While the specific evaluation method described may not be appropriate for all situations, it may serve as a model for the development of similar programs in other settings.

Information about barriers to planned change: a randomized controlled trial involving continuing medical education lectures and commitment to change.

PURPOSE: To determine whether practicing physicians receiving only clinical information at a traditional continuing medical education (CME) lecture (control group) and physicians receiving clinical information plus information about barriers to behavioral change (study group) would alter their clinical behaviors at the same rate. METHOD: In a randomized controlled trial, the investigators matched 13 pairs of U.S. and Canadian medical schools, assigning one school from each pair to study or control conditions. Following the commitment-to-change model, the investigators asked the primary care physicians attending control or study lectures on the management of cardiovascular risks whether they intended to make behavioral changes as a result of participating in the lectures and, if so, to indicate the specific changes. Thirty to 45 days later, the investigators surveyed the responding physicians to learn whether they had implemented those changes. RESULTS: Information about barriers to change did not increase the likelihood that physicians in the study group would report successful changes; they were no more likely to change than those in the control group. However, the physicians in both study and control groups were significantly more likely to change (47% vs 7%, p < .001) if they indicated an intent to change immediately following the lecture. CONCLUSIONS: Successful change in practice may depend less on clinical and barriers information than on other factors that influence physicians' performances. To further develop the commitment-to-change strategy in measuring the effects of planned change, it is important to isolate and learn the powers of individual components of the strategy as well as their collective influence on physicians' clinical behaviors.

The instructional effectiveness of a radiology multimedia textbook (HyperLung) versus a standard lecture.

RATIONALE AND OBJECTIVES: Information overload is a significant problem for the modern radiologist. This prospective study compares the instructional effectiveness of a multimedia textbook (HyperLung) with a lecture. HyperLung is a radiologic multimedia textbook about imaging diffuse lung disease created using a multimedia authoring tool, the Annotator (the University of Iowa Second Look Computing, Iowa City, IA), on the Apple Macintosh computer (Apple Computer, Cupertino, CA). METHODS: Forty-nine staff physicians and residents in the Department of Radiology were randomized to receive instruction either by HyperLung or by a lecture. The instructional content was the same in both groups, and both groups were tested before and after instruction. The actual time spent in each instructional situation was recorded. RESULTS: The instructional effectiveness of the multimedia textbook and lecture was equal. The instructional efficiency of HyperLung was only 60% of the lecture. Users of the multimedia textbook found it enjoyable and straightforward to use. CONCLUSIONS: Multimedia textbooks have a promising future in radiology education.

Small-group discussion versus lecture format for third-year students in obstetrics and gynecology.

OBJECTIVE: To compare lecture and small-group discussion for third-year medical students in obstetrics and gynecology. METHODS: Over a 2-year period, 91 third-year medical students in the obstetrics and gynecology clerkships were given educational sessions on diabetes and hypertension in pregnancy by a single instructor, either in a traditional lecture format or in a small-group discussion. After the instructional sessions, students anonymously completed a 20-question multiple-choice examination on the covered topics. They also completed an evaluation form on the instructional format, using a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). At the completion of each clerkship, students repeated the same multiple-choice examination. RESULTS: There was a significantly higher level of enjoyment (median value 5 versus 4, P <.001) and sense of educational stimulation (median value 5 versus 4, P <.001) in the discussion group, and students in the discussion group were less desirous of the alternate instructional format than those in the lecture group (median value 2 versus 3, P <.001). However, there were no differences in the test scores, either immediately after the instructional sessions or at the end of the clerkships. There was a 90% power to detect a 15% difference in postinstructional test scores. CONCLUSION: Third-year medical students learning about hypertension and diabetes in pregnancy during their obstetrics and gynecology clerkship strongly preferred small-group discussions over traditional lectures. However, this preference did not lead to improved test scores on these subjects.

Lecturer practitioners in UK nursing and midwifery: what is the evidence? A systematic review of the research literature.

BACKGROUND: Lecturer practitioner roles have been widely established in the UK, and are seen as having the ability to overcome the theory-practice gap in nursing, as well as offering other benefits including functioning as a link between education and practice. AIMS AND OBJECTIVES: This article systematically reviews the research literature on UK lecturer practitioner roles in nursing and midwifery, in order to construct a picture of the themes that emerge from their national implementation. CONCLUSIONS: Only eight published research studies meeting the inclusion criteria were identified in journals, and five more included from the 'grey literature', totalling 13 suitable research reports. Of these 13 papers, six involved nurses and midwives. Key themes from the literature are outlined and discussed. There is an overwhelming preference for qualitative methodologies, although there is a strong argument for quantitative work in mixed-methods studies. RELEVANCE TO CLINICAL PRACTICE: Lecturer practitioner roles can make an important contribution to nursing and midwifery education, but this is problematic. It is essential that managers clarify the purpose, responsibilities, support and review of lecturer practitioner roles if they are to be successful.

Introducing a lecturer-practitioner: the management perspective.

The West Midlands Regional Health Authority Department of Nursing funded a 1-year study to look at 'Implementation aspects of the lecturer-practitioner role (in nursing)'. A feasibility study was carried out from November 1992 to October 1993 to address the issue and highlight areas requiring more in-depth study. Twenty-nine subjects working as or with lecturer-practitioners were interviewed using a semi-structured questionnaire. The interview was divided into two discrete parts. The first section contained a mixture of open and closed questions and the second section adopted a modified repertory grid technique. This paper provides the main results from the first half of the interview. The study describes in practical terms how managers need to plan for the introduction of a lecturer-practitioner post; the key responsibilities of the role; and a person specification. The work identifies clear prerequisite criteria for job role and gives guidance on lecturer-practitioner management and function.
