Learning human anatomy: does learning occur during a lecture?

Information uptake during a formal lecture was evaluated using a sample of 43 second-year medical students to whom a topic on human developmental anatomy was presented. The sample was divided into two groups: Blue (group B) (21 students) and Red (group R) (22 students). Prior to the lecture, a pre-test of 20 multiple choice questions was administered to each group. The lecture was then delivered over 50 minutes. Both in its preparation and presentation, the lecture conformed to the principles of programmed instruction. After a 10-minute students' question-and-answer session, a post-test was served. For group B, this was group R's pretest while group R, in turn, received group B's pretest. No question in the pre-test was repeated in the post-test. Intergroup comparisons of pre-test scores and of post-test scores revealed non-significant differences (P greater than 0.05), thus confirming that the pre- and the post-tests were of comparable difficulty. In each group, the mean post-test score was significantly higher than the pre-test score (P less than 0.001). The pooled scores indicated that the percentage mastery of material presented during the lecture increased from -1.8% to 58.4%. These results demonstrate that significant learning can occur during a lecture prepared and delivered in accordance with sound pedagogical principles.     

Evaluation of a surgical simulator for learning clinical anatomy

BACKGROUND: New techniques in imaging and surgery have made 3-dimensional anatomical knowledge an increasingly important goal of medical education. This study compared the efficacy of 2 supplemental, self-study methods for learning shoulder joint anatomy to determine which method provides for greater transfer of learning to the clinical setting. METHODS: Two groups of medical students studied shoulder joint anatomy using either a second-generation virtual reality surgical simulator or images from a textbook. They were then asked to identify anatomical structures of the shoulder joint as they appeared in a videotape of a live arthroscopic procedure. RESULTS: The mean identification scores, out of a possible score of 7, were 3.1 +/- 1.3 for the simulator group and 2.9 +/- 1.5 for the textbook group (P = 0.70). Student ratings of the 2 methods on a 5-point Likert scale were significantly different. The simulator group rated the simulator more highly as an effective learning tool than the textbook group rated the textbook (means of 3.2 +/- 0.7 and 2.6 +/- 0.5, respectively, P = 0.02). Furthermore, the simulator group indicated that they were more likely to use the simulator as a learning tool if it were available to them than the textbook group was willing to use the textbook (means of 4.0 +/- 1.2 and 3.0 +/- 0.9, respectively, P = 0.02). CONCLUSION: Our results show that this surgical simulator is at least as effective as textbook images for learning anatomy and could enhance student learning through increased motivation. These findings provide insight into simulator development and strategies for learning anatomy. Possible explanations and future research directions are discussed.     

Bridging the transfer gap: laboratory exercise combines clinical exposure and anatomy review

Objectives  One of the goals of medical education is to bridge the gap between basic science and clinical practice. Students acquire basic science knowledge during their pre-clinical years, yet have limited opportunities to apply this knowledge clinically. This hands-on laboratory exercise was designed to facilitate a review of anatomy in the context of select clinical procedures, highlighting the application of anatomical concepts in clinical practice.
Methods  In 2008, Year 2 medical students participated in a clinical procedures laboratory taught by senior residents and attending physicians. Before participating, all students completed anatomy and clinical pre-tests and received syllabi detailing the select procedures and the anatomy pertinent to each. Students were organised into experimental (EG, n  = 48) and control (CG, n  = 17) groups. The EG observed and practised five procedures on cadavers and the CG participated in a traditional anatomy review laboratory with no procedural demonstrations or practice. Anatomy and clinical post-tests were administered to both groups following the 3-hour interventions. Surveys and focus sessions were used to assess student opinions.
Results  Scores on the anatomy pre- and post-tests were compared and were found to have significantly increased ( P  ≤ 0.015) in each group, with the EG performing better than the CG ( P  = 0.001). The EG also showed significant improvement in clinical post-test scores ( P  < 0.001). Clinical test scores in the CG did not improve ( P  = 0.393).
Conclusions  Review of anatomy coupled with the teaching of clinical procedures results in an anatomical review superior to that of traditional methods, enhances knowledge of clinical procedures, and heightens students' awareness of the relationships between basic science and clinical practice.     

Training medical students in HIV/AIDS test counselling: results of a randomized trial

The study assessed the effectiveness of a programme aimed at increasing medical students' skills in counselling patients presenting for HIV testing/AIDS information. Senior medical students were randomly assigned to receive a short course in pre- and post-test counselling, or to a control group which received the usual curriculum. The students' performance in counselling simulated patients was videotaped at baseline and after 3 months. A subsample was also assessed at 12 months. Students receiving the programme showed significantly greater improvement in pre- and post-test counselling skills over 3 months than did the controls. For the subsample continuing to 12 months, a significant effect over time was found; however, there was no significant difference between the groups. This may have been influenced by the small sample sizes used for the 12-month assessment. General interactional skills improved for the overall sample over 3 and 12 months, but again there were no significant differences between groups. Those exposed to the programme did not show significantly greater changes in either knowledge or attitude scores over either time frame, compared with controls. When taught in addition to the usual undergraduate curriculum at Newcastle University, this short interactional skills course significantly enhanced students' ability to provide pre- or post-test counselling for HIV/AIDS.     

Website navigation and surgical education

We evaluated the way in which medical students interacted with a surgical education Website. Ten medical students on their paediatric surgery rotation were asked to study online a chapter on intussusception in young children, for a period of 1 h. The computer was connected by video link to a video-recorder that recorded their navigation movements, i.e. navigation time, time spent in front of each page, stepwise, progressive exploration of the surgical contents, and use of interactive links. The students were asked to complete a questionnaire to identify their overall competency in computers and Internet navigation capabilities. The mean time spent viewing the entire Website was 48 min (range 31-63) and the mean time spent on the assigned chapter was 38 min (range 8-53). Each page out of 14 within the chapter was visited a mean of 1.8 times (range 0-10). Access to video selections occurred after a mean of 10 min after beginning the session. A connection was made to the video a mean of 2.3 times per session. The mean time spent viewing video footage was 9 min (24% of the time spent viewing the chapter). The questionnaire results showed that few students regularly accessed the Internet for educational purposes.     

Interactional skills of students from traditional and non-traditional medical schools before and after alcohol education

OBJECTIVE: To compare alcohol-related intervention and general interactional skills performance of medical students from a traditional (Sydney) and a non-traditional (Newcastle) medical school, before and after participation in an alcohol education programme about brief intervention. DESIGN: In two controlled trials, students received either a didactic alcohol education programme or didactic input plus skills-based training. Prior to and after training, all students completed videotaped interviews with simulated patients. SETTING: The Faculties of Medicine at the University of Newcastle and the University of Sydney, Australia. SUBJECTS: Fifth-year medical students (n=154). RESULTS: Both alcohol-related intervention and general interactional skills scores of the Newcastle students were significantly higher than those of the Sydney students at pre-test but not after training. Although alcohol-related interactional skills scores improved after training at both universities, they did not reach a satisfactory level. The educational approach used had no effect on post-test scores at either university. CONCLUSIONS: Significant baseline differences in interactional skills scores favouring non-traditional over traditional students were no longer evident after both groups had been involved in an alcohol education programme. Further research is required to develop more effective alcohol intervention training methods.     

Videotaped vs traditional lectures for medical students

Closed-circuit television (CCTV) provides medical departments with alternatives in instructional formats. Concern, however, has been voiced about teaching via TV because the medium itself might cause inattention. This study investigated whether TV will lower the test scores of medical students. Sixty-one students were randomly divided into two groups. The lecture (control) group received the information via traditional lectures, including use of 2”× 2” transparencies. The video group received concurrently the same information via CCTV. Multiple-choice examinations were given after each of the six sessions. The cumulative mean scores were similar: lecture group = 87.56%, video group = 87.99%, i.e., no significant difference (P=0.77). To detect attitudinal differences toward the two formats, the students were surveyed at the end of the series and intragroup agreement on specific questions was calculated. The students rated the lecture format more highly. In response to the question ‘Did the audiovisual materials used by the instructor aid your learning?’, the mean rating from the lecture group was 7.37 (scale of 0–9) compared to a mean rating of 5.93 from the video group (P< 0.0003).

Virtual reality and brain anatomy: a randomised trial of e-learning instructional designs

CONTEXT: Computer-aided instruction is used increasingly in medical education and anatomy instruction with limited research evidence to guide its design and deployment. OBJECTIVES: To determine the effects of (a) learner control over the e-learning environment and (b) key views of the brain versus multiple views in the learning of brain surface anatomy. DESIGN: Randomised trial with 2 phases of study. Participants Volunteer sample of 1st-year psychology students (phase 1, n = 120; phase 2, n = 120). Interventions Phase 1: computer-based instruction in brain surface anatomy with 4 conditions: (1) learner control/multiple views (LMV); (2) learner control/key views (LKV); (3) programme control/multiple views (PMV); (4) programme control/key views (PKV). Phase 2: 2 conditions: low learner control/key views (PKV) versus no learner control/key views (SKV). All participants performed a pre-test, post-test and test of visuospatial ability. MAIN OUTCOME MEASURES: A 30-item post-test of brain surface anatomy structure identification. RESULTS: The PKV group attained the best post-test score (57.7%) and the PMV group received the worst (42.2%), with the 2 high learner control groups performing in between. For students with low spatial ability, estimated scores are 20% lower for those who saw multiple views during learning. In phase 2, students with the most static condition and no learner control (SKV) performed similarly to those students in the PKV group. CONCLUSIONS: Multiple views may impede learning, particularly for those with relatively poor spatial ability. High degrees of learner control may reduce effectiveness of learning.     

Objective-structured teaching of undergraduate neurology

Medical students at two teaching institutions were given an objective list containing information thought to be of maximum neurological teaching value. The usefulness of the objective list was assessed by giving the students pre- and post-tests containing questions that were derived from the objective list. Irrespective of the disparity in the clinical teaching programme, there was no significant difference between test scores of students who rotated at the two institutions. Comparison of pre- and post-test scores showed a highly significant improvement (P less than 0.005) in test scores. An objective list should be part of an effective undergraduate teaching programme in neurology.     

Does computer‐assisted instruction really help to improve the learning process?

OBJECTIVES: We have developed both a computer-assisted instruction (CAI) multimedia program and a textbook on arterial blood gas interpretation with the same content as formal didactic instruction. A prospective, randomized study was designed to compare the outcomes of self-learning using the software and using the textbook. METHODS: 80 third-year medical students were randomly allocated to two groups: the CAI (n=40) and text group (n=40). A 30-item, type-K examination was administered as the pre-test. After the pre-test, the volunteers in the CAI group studied the software program, whereas those in the text group spent their time reading the textbook covering the same material. The post-test was held immediately at the end of a full day of study, and 3 weeks later, the final test was performed without prior notice. A P value of <0.05 was considered to be a statistically significant difference. RESULTS: Students in the text group seemed to fulfil their assignments and improved their scores post-test better than those in the CAI group. After 3 weeks, the final test scores of both groups demonstrated a significant decrease, but showed an insignificant difference between the two groups. CONCLUSION: Text-based learning seems to be a convenient method of education where time is limited. However, with more time available, use of software may be as good as the conventional learning method and can be an alternative tool. The computer-assisted instruction program seems to enhance the learning process.     

Impact of a new course on students' potential behaviour on encountering ethical dilemmas

OBJECTIVE: To evaluate the effectiveness of small-group ethics teaching in an integrated medical curriculum. DESIGN: A quasi-experimental, pre- and post-test, non-equivalent control group design. SETTING: University of Glasgow Medical School. SUBJECTS: 111 first-year students from Glasgow University's new learner-centred medical curriculum, with a control group of 51 students from the last year of the traditional curriculum. MAIN OUTCOME MEASURE: Student answers consistent with consensus professional judgement on the ethical dilemmas posed by the vignettes of the Ethics and Health Care Survey Instrument. RESULTS: There was a significantly greater increase in the number of post-test consensus answers in the experimental group (P=0.0048): the odds ratio for obtaining the post-test consensus answer in the experimental group compared with the control group was 1.73 (95% confidence interval 1.28-2.33). Significant movement towards consensus occurred in the areas of autonomy, confidentiality and consent. Among controls there was a significant move away from consensus in the area of "whistle blowing" on colleagues (P=0.017). CONCLUSION: Small-group ethics teaching, in an integrated medical curriculum, had a positive impact on the first-year students' potential ethical behaviour. It was more effective than a lecture and a large-group seminar-based course in developing students' normative identification with the profession of medicine.     

Use of commercial ''authoring systems'' for medical education

A recent development in computer-assisted medical instruction has been the introduction of 'authoring systems'. Authoring systems are computer programs which can allow an instructor to prepare computer-based medical instructional materials without the need to know programming languages or have more than minimal familiarity with the computer hardware. This report documents the use of a commercially available authoring system that was used to prepare a tutorial for medical student instruction. This lesson presented information about paediatric developmental disabilities in both a text and question-and-answer format. Significant improvement in knowledge was demonstrated by the pre- and post-test results of the study group compared to the control group. The control group consisted of students who did not view the tutorial but had been assigned to a paediatric developmental disabilities clinic. The medical students who viewed the tutorial generally had very favourable comments about the use of such a system for the presentation of new information.     

Changes in moral reasoning and the teaching of medical ethics

Courses in medical ethics are becoming an integral part of many medical school curricula in Europe. At the medical school of the University of Copenhagen, a course on philosophy of medicine has been compulsory for all medical students since 1988. The effect of such courses on the ethical awareness and reasoning of medical students is not well understood and we have therefore found it of interest to study the effects of the Copenhagen course. For the study, we used a Danish version of the Defining Issues Test (DIT) which measures development in moral reasoning (Rest J R, 1979 Development in Judging Moral Issues. University of Minnesota Press, Minneapolis).
The study was conducted as a pre- and post-test study without a control group, and the subjects were all medical students attending the course in the autumn of 1993.
The results show that moral reasoning scores measured by the DIT increase significantly, and we argue that this increase can only be explained as an effect of the course.     

The use of an objective structured clinical examination (OSCE) for formative and summative assessment in a general practice clinical attachment and its relationship to final medical school examination performance

OBJECTIVES: To report the use of OSCEs for both formative and summative purposes within a general practice undergraduate clinical attachment and to compare student performance in the departmental OSCEs with that of their final medical school examinations. METHODS: Twenty-eight students rotated through the attachment and undertook pre- and post-attachment OSCEs of similar format but different content. Results were analysed to determine relationships between mean scores in the two OSCEs and student performance in their final medical school MBBS examinations. RESULTS: There was a marked improvement in all OSCE station scores. Pre-attachment scores for those stations measuring physical examination and problem-solving skills were unrelated to prior clinical experience. Post-attachment OSCE mean scores were significantly correlated with final examination OSCE and total mean scores. CONCLUSION: The general practice attachment appears to upgrade those clinical skills measured by the pre- and post-attachment OSCE, however, there was no control group of students. Problem-solving and focused physical examination skills need to be targeted by all undergraduate clinical departments. The department's post-attachment OSCE and total assessment results are predictors of final examination OSCE and total results. The use of pre- and post-attachment OSCEs facilitates both students' formative learning processes and the department's evaluation of its educational programme.     

Medical students' viewpoint regarding the integrated module of basal ganglia

Integration is an important educational strategy in medical education. Considering this idea, the goal of the present study was to design and implementation of longitudinal and vertical integrated education of anatomy, physiology, pharmacology, neurology and neuropsychiatry subjects of brain's basal ganglia by a multidisciplinary team. Kern's approach to curriculum development was used. Participants were 20 medical students at basic science level who contribute in a 10 stations of pre-test exam at Medical School's Skill Lab. After the implementation of the module by a multidisciplinary team, post-test were done. A structured questionnaire was designed to assess student opinions about adequacy, usefulness of the module using a Likert scale with 5 categories ranging from "completely agreement" to "completely disagreement". The result of pre and post-test were also compared. Twenty questionnaires were completed, giving a 77.63% satisfaction rate. Seventy-five percent of students found it useful and appropriate at basic science level. About fifty percent of students suggested the implementation of this module for other medical students. The score of post-test was significantly (14.52 ± 0.47 vs 6.32 ± 0.62, P < 0.05) higher than pre-test results. The viewpoints of medical students were positive and they value the module highly. Since it is not easy to change the style we teach, these results suggest necessitate of supporting the faculty member's participation in these modules.     

Learning basic surgical skills with mental imagery: using the simulation centre in the mind

Context  Although surgeons and athletes frequently use mental imagery in preparing to perform, mental imagery has not been extensively researched as a learning technique in medical education.
Objective  A mental imagery rehearsal technique was experimentally compared with textbook study to determine the effects of each on the learning of basic surgical skills.
Methods  Sixty-four Year 2 medical students were randomly assigned to 2 treatment groups in which they undertook either mental imagery or textbook study. Both groups received the usual skills course of didactic lectures, demonstrations, physical practice with pigs' feet and a live animal laboratory. One group received additional training in mental imagery and the other group was given textbook study. Performance was assessed at 3 different time-points using a reliable rating scale.
Results  Analysis of variance on student performance in live rabbit surgery revealed a significant interaction favouring the imagery group over the textbook study group.
Conclusions  The mental imagery technique appeared to transfer learning from practice to actual surgery better than textbook study.     

Probabilistic atlas and geometric variability estimation to drive tissue segmentation

Computerized anatomical atlases play an important role in medical image analysis. While an atlas usually refers to a standard or mean image also called template, which presumably represents well a given population, it is not enough to characterize the observed population in detail. A template image should be learned jointly with the geometric variability of the shapes represented in the observations. These two quantities will in the sequel form the atlas of the corresponding population. The geometric variability is modeled as deformations of the template image so that it fits the observations. In this paper, we provide a detailed analysis of a new generative statistical model based on dense deformable templates that represents several tissue types observed in medical images. Our atlas contains both an estimation of probability maps of each tissue (called class) and the deformation metric. We use a stochastic algorithm for the estimation of the probabilistic atlas given a dataset. This atlas is then used for atlas‐based segmentation method to segment the new images. Experiments are shown on brain T1 MRI datasets. Copyright © 2014 John Wiley & Sons, Ltd.     

Online diabetes education: design and evaluation with prospective diabetes camp counsellors

An educational Website was designed by the Florida Initiative in Telehealth and Education group, and an online diabetes education test was developed using a sample of 60 children and young adults aged 8-22 years, all of whom had diabetes. The 31 items were analysed for item difficulty. Eight test items were eliminated as being unsuitable. The test was then used in 67 prospective diabetes counsellors (23 men, 44 women) who volunteered for a summer camp. Camp counsellors ranged in age from 17 to 33 years (mean 22 years, SD 3). The counsellors' mean pre-test scores were 80% and their mean post-test scores were 92%. There was a significant improvement (P=0.001) of approximately 1.25 questions from pre- to post-test. This supports the use of the online educational Website for training individuals working with children with diabetes. The Website may prove to be useful for online education in other areas of diabetes management.     

Effect of Concept Mapping Education on Critical Thinking Skills of Medical Students: A Quasi-experimental Study

BackgroundFostering critical thinking (CT) is one of the most important missions in medical education. Concept mapping is a method used to plan and create medical care through a diagrammatic representation of patient problems and medical interventions. Concept mapping as a general method can be used to improve CT skills in medical students. The aim of this study was to explore the effect of concept mapping on CT skills of medical students.MethodsThis quasi-experimental study was conducted on 100 second-year medical students which take an anatomy course. Participants were randomly assigned into a control group (lecture-based) and an intervention group (concept mapping). CT levels of medical students were assessed using the California Critical Thinking Skills Test. Data were analyzed using independent sample t-test.ResultsBefore intervention, CT scores of the intervention and control groups were 6.68 ± 2.55 and 6.64 ±2.74, respectively, and after intervention, they were 11.64 ±2.29 and 10.04 ± 3.11, respectively. Comparison of mean score differences for both groups before and after intervention demonstrated that CT scores in the experimental group significantly increased after intervention (P=0.021).ConclusionsMedical students who were taught through concept mapping showed an increase in CT scores, compared with those in the control group. Medical students require effective CT skills in order to make sound knowledge-based assessment and treatment choices during patient care. Therefore, instructors and planners of medical education are expected to apply this educational strategy for developing CT skills in medical students.
