The benefits of flexibility: the pedagogical value of instructions to adopt multifaceted diagnostic reasoning strategies

Objectives Building on the advice of previous research to avoid parsing diagnostic strategies too finely, recent studies have shown that teaching novices to utilise analytic and non‐analytic reasoning strategies yields higher diagnostic accuracy than teaching either in isolation. This study assesses the extent to which students spontaneously adopt a combined approach and compares its benefits with those experienced with a contrastive learning strategy known to enhance analogical transfer. Methods A sample of 48 naïve students were trained to identify features on electrocardiograms (ECGs) and assign diagnoses. Half the participants learned in a standard manner, encountering diagnoses (and their associated features) in sequence. The remaining participants were explicitly instructed to draw comparisons between the diagnostic category being learned and another confusable diagnostic category (contrastive learning). Half the participants in both groups were further instructed to carefully identify all features while trusting guidance provided by feelings of familiarity (a combined reasoning strategy). The remaining participants were given no instructions on how to approach the diagnostic task. Results Greater diagnostic accuracy was achieved following both contrastive learning and instructions to use a combined reasoning strategy relative to the control conditions. These variables did not interact with each other, nor did they interact with novelty of the test case. The effects were observed immediately after learning and following a 1‐week delay. Discussion The results emphasise the importance of explicitly empowering students to utilise multiple diagnostic strategies, including non‐analytic approaches. In addition, this study reveals the benefit that can be gained from contrastive learning in a medical domain.     

A case-based anatomy course

Summary. A course is described in which the students give consideration to clinical cases as they review their current knowledge, and follow a set protocol which guided them in preparing their learning. The students are required to examine a case history, put down as key words either their first answer or the knowledge they consider they would need to answer specific questions. They then select stations at which additional information, wet specimens, models and radiological images assist them in upgrading their knowledge. They complete the exercise by writing a final answer to the questions on the case. The tutor is able through examination of the key words to determine the knowledge of the students as they enter, and confirm appropriate learning by inspection of the final answer. The students are able to identify their own deficiencies, develop strategies for thinking and learning, resulting in the acquisition of expertise in problem solving, and extend their communication skills by working with colleagues. While the course was designed for second-year anatomy teaching it could be applied to other disciplines.     

Does teacher thinking match teaching practice? A study of basic science teachers

OBJECTIVE: To obtain an understanding of basic science medical teachers' conceptions of learning and their ideas for facilitation of learning. METHODS: Teaching staff at a biomedical centre (n = 62) were asked to describe their definitions of learning, their suggestions for how to solve an applied educational problem and their intended activities when teaching students. The research was carried out using a questionnaire consisting of open-ended and fixed-choice questions. RESULTS: Although 1 in 4 teachers endorsed constructivist conceptions of learning, only 1 in 8 actually reported using activating teaching strategies. Conceptions of learning did not co-vary with teaching practice. CONCLUSIONS: The assumption that conceptions of learning and teaching practice are aligned was challenged. The current questionnaire could be used as an intervention tool for educational development to map whether or not there is a match between teachers' conceptions and their practice.     

Short-term outcomes and long-term impact of a programme in medical education for medical students

Objectives  There is growing appreciation of the value of early preparation of future medical educators. Staff development programmes, conferences and workshops pertaining to the training of educators may be crucial to the pursuit of a school's larger educational mission to educate students, doctors and scholars and to provide comprehensive knowledge, research, patient care and service. This study examined the efficacy of a 1-week educational intervention aimed at preparing medical students to become effective doctor educators by building skills early in their careers. The study asked whether participation in a 5-day teacher training programme led to increased knowledge of instructional methods, more favourable attitudes towards teaching, and the integration of structured instructional design methods in a student-developed teaching project.
Methods  A mixed methods research design was employed with quantitative data captured through pre- and post-test inventories, qualitative components captured through written comments, and a 2-year post-intervention survey. Quantitative analyses included pre-/post-intervention repeated measures with calculated effect sizes. Qualitative analysis was conducted using constant comparative methods.
Results  Subjects demonstrated improved content knowledge and more positive attitudes towards motivation, teaching confidence, teacher roles, varied pedagogy, and use of assessment, instructional planning, and evaluation. Subjects were able to incorporate the programme's teaching theory and methods into their teaching projects and assessment of peers' and others' teaching in their own institutions 2 years post-training.
Conclusions  This study demonstrates that a well-designed programme for teacher preparation can be pedagogically effective for training medical students to become better educators and that this learning can be incorporated into long-term practice.     

An evaluation of a workshop on educational methods for health science teachers in Lagos, Nigeria

A workshop on educational methods held at the College of Medicine, University of Lagos in 1980 was evaluated by means of questionnaires. The workshop was favourably received and enhanced the teaching practices of participants. As a result of the workshop, most participants wrote instructional objectives, used more audiovisual aids and adopted new methods of teaching and assessment of clinical skills. Although the session on the production of self-instructional packages (SIPs) was rated highly at the workshop, relatively few participants had completed a programmed text at time of follow-up. Similarly, most participants had set MCQs but few had calculated either the facility or discrimination index.
The participants themselves suggested that future workshops should be tailored to the particular educational needs of different disciplines. The authors suggest that intensive short-term workshops may be useful for content areas which require more time than an extensive workshop permits.     

Testing learning theories: the NUL hypothesis

INTRODUCTION: In the spirit of Scrooge and the Grinch, I describe the nasty unpalatable learning (NUL) hypothesis as a new theory of learning. This is an exercise to explore how difficult it would be to develop a new learning theory by reversing the social and altruistic tenets of most existing learning theories. THE NUL HYPOTHESIS: The NUL hypothesis has four propositions. These are: (1) the value of rote learning; (2) the usefulness of authority figures in teaching within a clear hierarchy; (3) the use of fear in teaching, and (4) the value of internal consistency without any necessary connection to the outside world. CONCLUSIONS: The NUL hypothesis may promote reflection not only on the construction of learning theories, but also on the design of critical experiments. It also seems to imply that efficiency may be a better measure of learning success than effectiveness.     

Martin's Map: a conceptual framework for teaching and learning the medical interview using a patient-centred approach

OBJECTIVE: At the end of training, students seem to lack a basic understanding of how to take an organised, relevant medical and social history using a patient-centred approach. The aim of developing the map described in this paper was to provide a framework for such an approach. METHODS: Action research was used to continuously modify and refine an interview map that was used by medical clerks, family medicine residents, international medical graduates and practising doctors for teaching and learning purposes over a 10-year period. CONCLUSION: 'Martin's Map' provides a realistic framework for flexibly organising and integrating medical content with process that did not previously exist. The map provides medical educators with a standardised framework for talking about the medical interview, which helps learners understand how to use their medical knowledge with a patient-centred approach. Learners are able to visually see how they can take a focused medical and social history using a patient-centred approach, which subsequently seems to help them organise their thinking and approach during the medical encounter.     

HIV/AIDS in the visual arts: applying discipline-based art education (DBAE) to medical humanities

CONTEXT AND RATIONALE: Health professions educators have been systematically attempting to insert the humanities into health professions curricula for over 4 decades, with various degrees of success. Among the several medical humanities, the visual arts seem particularly adequate for the teaching/learning of crucial aspects of medicine. Educational efforts in the arts require, however, a sound pedagogical philosophy of art education. Health professions educators need therefore to be aware of educational frameworks in the arts. Discipline-based art education (DBAE) is a recognised contemporary educational framework for the teaching/learning of the arts, which may be adapted to medical humanities. OBJECTIVE: It is the ultimate objective of this essay to share the experience of applying this educational framework to a course in a medical curriculum. METHODS: The author describes a course on the representations of HIV/AIDS in the visual arts, with explicit reference to its objectives, content, instructional features and student assessment in the light of DBAE, whose principles and characteristics are described in detail. RESULTS AND CONCLUSION: Discipline-based art education may be applied to medical humanities courses in a medical curriculum. This essay throws light on how this structure may be particularly useful for designing other pedagogically sound art courses in health professions curricula.     

Teaching sociology of medicine: the group process

As a part of any curriculum reorganization, new instructional methods are also tested. When the University of Turku sociology of medicine course was found to need renovation, its goals and objectives, content and instructional methods were closely examined and modified, in order to strengthen institutional and multiprofessional relations and reinforce sociocultural issues in doctors' competence with the patient. This paper discusses this change, emphasizing teaching and learning methodology.     

Using standardised students in faculty development workshops to improve clinical teaching skills

PURPOSE: We describe the use of standardised students (SSs) in interdisciplinary faculty development programmes to improve clinical teaching skills. Standardised students are actual health professions students who are trained to portray a prototypical teaching challenge consistently across many encounters with different faculty participants. METHODS: The faculty development programmes described focused on the skills of providing feedback and brief clinical teaching. At the beginning of each session, each participant was videotaped in encounters with 2 different SSs. Using microteaching (an instructional method in which learners view short segments of their own videotaped performance and discuss the tapes with a facilitator, consultant or other workshop participants), each group of participants and instructors reviewed the tapes and reflected on the encounters, providing immediate feedback to participants and modelling different approaches to the same teaching problem. The same process was repeated with more complicated scenarios after 2 weeks and again after 6 months offering reinforcement, further practice and more sophisticated development of the strategies learned. Participants completed post-session evaluations and a follow-up telephone survey. RESULTS: A total of 36 faculty members from the colleges of medicine, dentistry, pharmacy and nursing participated in workshops in 2000-01. The workshops were rated as highly relevant to participants' teaching, and most participants reported that they had learned a great deal. Participants most appreciated reviewing the videotaped interactions, the feedback they received, the interactions with their colleagues, the interdisciplinary nature of the groups and the practical focus of the workshops. CONCLUSIONS: Standardised students provide a high fidelity, low risk, simulated environment in which faculty can reflect on and experiment with new teaching behaviours. Such encounters can enhance the effectiveness and impact of faculty development programmes to improve clinical teaching skills.     

Introducing resident doctors to complexity in ambulatory medicine

Objectives Medical education instructional methods typically imply one ‘best’ management approach. Our objectives were to develop and evaluate an intervention to enhance residents’ appreciation for the diversity of acceptable approaches when managing complex patients. Methods A total of 124 internal medicine residents enrolled in a randomised, crossover trial. Residents completed four web‐based modules in ambulatory medicine during continuity clinic. For each module we developed three ‘complex cases’. Cases were intended to be complex (numerous variables, including psychosocial and economic barriers) and to suggest multiple acceptable management strategies. Several experienced faculty members described how they would manage each case. Residents reviewed each case, answered the same questions, and compared their responses with expert responses. Participants were randomly assigned to complete two modules with, and two modules without complex cases. Results A total of 76 residents completed 279 complex cases. Residents agreed that complex cases enhanced their appreciation for the diversity of ‘correct’ options (mean ± standard error of the mean 4.6 ± 0.2 [1 = strongly disagree, 6 = strongly agree]; P < 0.001). Mean preference score was neutral (3.4 ± 0.2 [1 = strongly favour no cases, 6 = strongly favour cases]; P = 0.72). Knowledge post‐test scores were similar between modules with (76.0 ± 0.9) and without (77.8 ± 0.9) complex cases (95% confidence interval for difference ? 4.0 to 0.3; P = 0.09). Resident comments suggested that lack of time and cognitive overload impeded learning. Conclusions Residents felt complex cases made a valuable contribution to their learning, although preference was neutral and knowledge scores were not affected. Methods to facilitate trainee comfort in managing medically complex patients should be further explored.     

Participants' opinions on the usefulness of a teaching portfolio

BACKGROUND: Whether teaching portfolios achieve their aim of stimulating teachers' professional development is favourably affected by the incorporation of a balanced structure and effective social interactions, such as coaching. We explored teachers' experiences with a teaching portfolio that was structured by teaching roles, portfolio assignments and conversation protocols. The related social interactions consisted of meetings with peers and personal coaches. Teachers' and coaches' opinions were sought about the benefits and the enabling and disabling factors of the portfolio structure and the social interactions involved. METHOD: Five teachers and their personal coaches were individually interviewed about their experiences with the portfolio. Protocols were analysed using a top-down strategy. RESULTS: The teaching roles were helpful in analysing teaching, but the assignments and the conversation protocols were too detailed and directive. The social interactions were perceived as very valuable for professional development, particularly the meetings with personal coaches. CONCLUSIONS: The portfolio structure and social interactions, especially personal coaching, appeared to be helpful for teachers in analysing their teaching practice. The assignments and protocols, however, were too detailed and directive. This may be resolved by using assignments and conversation protocols more flexibly and enabling adjustment to personal learning needs. The high appreciation of personal coaching might be related to the freedom for teachers to choose their own coach. The results can be used by portfolio designers as guidelines for how to achieve a balanced structure and effective social interactions and how these might be combined to increase the benefits of working with a portfolio to teachers.     

The quality of medical teaching and learning in rural settings: the learner's perspective

Summary. During 1992–93, the authors produced a video-based teacher development resource kit for rural and isolated general practitioners and hospital medical personnel who are involved in medical teaching. As part of the development process, we surveyed 240 medical undergraduate students of the University of Queensland about their experiences and perceptions of teaching and learning in rural settings in Queensland. For approximately 90% of undergraduate learners, the experience with a rural medical practitioner was extremely positive. The major positive features identified by students were: being treated as a colleague; being allowed/encouraged to work independently; receiving feedback on their work; and being given ample 'hands-on' minor procedural experience and/or teaching. The 10% of students who reported unfavourably on their rural terms identified lack of opportunities to carry out solo consultations/work independently, lack of structure in teaching/learning experiences, and lack of hands-on experience as the major disappointments. The results demonstrate clearly how and why the majority of rural medical teachers in Queensland are effective facilitators of undergraduate learning.     

Trialling a new way to learn clinical skills: systematic clinical appraisal and learning

AIM: To describe and evaluate the effectiveness of a new method of teaching clinical skills designed to increase students' active and self-directed learning as well as tutor feedback. METHODS: A total of 22 consenting Year 4 medical students undertaking general practice and general surgery clinical experience were involved in a pre- and post-test research design. In the initial period of the study, students were taught clinical skills in a traditional manner. In the second phase a clinical teaching strategy called systematic clinical appraisal and learning (SCAL) was utilised. This learning strategy involved active and self-directed learning, holistic care and immediate feedback. Students independently saw a patient and were asked to make judgements about the patient's potential diagnosis, tests required, management, psychosocial needs, preventive health requirements, and any ethical problems. These judgements were then compared with those of the clinical supervisor, who saw the same patient independently. Students recorded details for each consultation. Comparisons were made of the two study periods to examine whether the use of SCAL increased the number of students' independent judgements, perceived student learning, tutor feedback and self-directed learning. RESULTS: During the SCAL learning period, students reported making a greater number of statistically significant independent judgements, and receiving significantly increased tutor feedback in both general practice and general surgery. The number of learning goals set by students was not found to differ between the two periods in surgery but significantly increased in general practice in the SCAL period. Students' perceptions of their learning significantly increased in the SCAL period in surgery but not in general practice. During the traditional learning period in both settings, there was limited student decision-making about most aspects of care, but particularly those relating to prevention, psychosocial issues and ethics. CONCLUSIONS: The SCAL approach appears to offer some advantages over traditional clinical skills teaching. It appears to encourage active and independent decision-making, and to increase tutor feedback. Further exploration of the approach appears warranted.     

A teachers' guide to teaching medical interviewing

Success in teaching a course in medical interviewing requires competence on the part of instructors, who also need training, and have to provide a structured approach. Problems encountered by course coordinators at the Department of Family Medicine, University of Miami School of Medicine, Miami, Florida have been: (1) a shortage of skilled teachers; (2) inadequate motivation of instructors for teaching the course; (3) differences in content, teacher's style, and outcomes from small groups; and (4) ambiguities in structure or guidelines provided for teachers. The development of a teacher's guide, giving specific objectives and step-by-step methods for teaching significantly improved teacher satisfaction and commitment to the course, as well as student learning.     

Anatomy 1999–2000: the curriculum,who teaches it and how?

AIM: To review the impact of Tomorrow's Doctors on anatomical teaching in the UK and Ireland. To establish in particular whether a consensus has emerged on: (a) the duration and format of teaching, and (b) the impact on staffing and on the four main anatomical disciplines of gross anatomy, histology, embryology and neuroanatomy. METHOD AND RESULTS: A postal survey of 28 anatomy departments was carried out. This yielded a response rate of 75%. Twelve departments used systems-based curricula, five used problem-based curricula, and four used a traditional regional format. There were variable levels of integration between the anatomical disciplines and subjects outside anatomy. Dissection taught over the first 2 years was retained in 76% of the courses, frequently supplemented with demonstrations, with an average of 2 hours of practical work for every hour of lecture. Staff/student ratios varied with the type of curriculum: dissection room teaching and problem-based curricula were associated with higher numbers of either full or part-time clinically qualified teachers. Teaching was supported by a high proportion of part-time clinically qualified staff, giving an overall average staff/student ratio of 19.8 in a dissection class. CONCLUSIONS: There is considerable variation in duration and staffing of anatomy teaching, according to the type of curriculum. This suggests there may well be substantial variation in the level, content and depth of anatomical curricula across the country, and that this should be quantified.     

Continuing Medical Education Case Study Series

Increasing interest in continuing medical education is reflected in greater demand for educational programmes. Content and educational strategies should be appropriate to the needs of the target audience. Proper matching of content and strategies to target needs of users requires the instructional design to be carefully planned and based on a needs-assessment study. We illustrate the influence of educational needs on content and learning strategies through an educational programme for general practitioners on the subject of malignant melanoma. Its design includes: i. a trigger leaflet; ii. a core text; iii. a set of interactive case studies; iv. a job-aid card; v. a follow-up leaflet; and vi. recorded messages available by telephone. It addressed, in particular, the key decision to be taken by the general practitioner: ‘When should I refer a patient with a suspected early melanoma: when should I merely reassure the patient?’ Doctors were invited, in the programme, to make decisions about referral of patients. They received immediate feedback on their decisions. Various strategies reinforced this feedback.     

Teaching doctors how to diagnose paroxysmal events: a comparison of two educational methods

Objectives  Two educational methods, facilitated case discussion and a computerised tutorial, were compared for teaching about childhood epilepsy. We used a comprehensive and clinically relevant assessment method to evaluate the hypothesis that a computerised tutorial more effectively increases knowledge acquisition than a facilitated case discussion.
Methods  Paediatric trainees ( n  = 66) were arbitrarily allocated to facilitated case discussion or computerised tutorial. The analysis of paroxysmal events was taught by the same teacher, using a standardised protocol and principles of active learning. Outcome measures included knowledge acquisition, clinical confidence and usefulness pre- and post-teaching, and at 3 months follow-up.
Results  Computerised tutorial participants scored significantly higher on knowledge acquisition post-teaching. There was gain in clinical confidence in both modalities post-teaching which did not differ between the groups. Confidence and knowledge were not related post-teaching. Both groups found the teaching relevant to clinical practice. However, facilitated case discussion participants rated the session as more enjoyable, and more useful in reinforcing and acquiring knowledge, and felt more motivated for further learning. At 3 months follow-up, participants in both modalities showed significant increases in knowledge acquisition, with no difference between modalities.
Conclusions  The computerised tutorial more effectively imparted knowledge immediately post-teaching. However, facilitated case discussion is the preferred modality in terms of participant enjoyment and perceived usefulness.     

Effectiveness of using blended learning strategies for teaching and learning human anatomy

OBJECTIVES: This study aimed to implement innovative teaching methods--blended learning strategies--that include the use of new information technologies in the teaching of human anatomy and to analyse both the impact of these strategies on academic performance, and the degree of user satisfaction. METHODS: The study was carried out among students in Year 1 of the biology degree curriculum (human biology profile) at Pompeu Fabra University, Barcelona. Two groups of students were tested on knowledge of the anatomy of the locomotor system and results compared between groups. Blended learning strategies were employed in 1 group (BL group, n = 69); the other (TT group; n = 65) received traditional teaching aided by complementary material that could be accessed on the Internet. Both groups were evaluated using the same types of examination. RESULTS: The average marks presented statistically significant differences (BL 6.3 versus TT 5.0; P < 0.0001). The percentage pass rate for the subject in the first call was higher in the BL group (87.9% versus 71.4%; P = 0.02), reflecting a lower incidence of students who failed to sit the examination (BL 4.3% versus TT 13.8%; P = 0.05). There were no differences regarding overall satisfaction with the teaching received. CONCLUSIONS: Blended learning was more effective than traditional teaching for teaching human anatomy.
