Does the introduction of Non-Traditional Teaching Techniques Improve Psychology Undergraduates' Performance in Statistics?

We report a study in which five non-traditional teaching techniques were applied to an introductory statistics course for psychology undergraduates: active and implicit learning, use of breaks, mastery learning, peer tutoring and problem-based learning. Collectively, these techniques improved students' scores in a statistics examination by ten percent compared with a matched control group and this improvement was statistically significant. Students' responses to the new course were positive.

A structured PBL tutorial involving small teams for teaching the human nervous system

BACKGROUND

The Human Nervous System and Behavior course at Harvard Medical School (HMS) incorporates a hybrid model of problem-based learning. Student preparation for and participation in the tutorial seemed to be insufficient.

AIMS

We sought to increase student engagement in tutorial by creating a structured approach, which included assigned roles for students, weekly testing, formal cornerstone presentations, and a weekly self-assessment exercise. We wished to determine the students' and tutors' satisfaction with this structured approach as compared with the more traditional tutorial experienced in other courses at HMS.

METHODS

For the first 4 years of the course, students (n = 160) were surveyed concerning their impressions of the quality of the structured approach in comparison with the traditional tutorial. In addition, they were surveyed concerning the cornerstone presentations and the self-assessment exercise. Tutors (n = 10) who had taught in both the traditional and structured tutorial formats were surveyed about their impressions of student performance as well as their own enjoyment in the structured format.

RESULTS

Students and tutors found the structured approach superior to the previous method. Both groups noted increased student preparation, participation, and accountability. Tutors preferred teaching in the structured format.

CONCLUSIONS

The structured approach increased student accountability, preparation, and participation. Students and tutors preferred this tutorial experience over the previous approach.

Problem-based learning: where are we now?

The definition of problem-based learning (PBL) as an educational concept is as elusive in 2008 as it has been since the concept was first expressed over forty years ago. A definitive guide to the practice of PBL is equally elusive. Like all worthwhile educational ideas, PBL has proved attractive to those teachers who seek improvements for their courses. Its appeal has transcended the traditional boundaries in formal education so that there are examples of PBL from primary to tertiary education, and across many disciplines within these. Dissemination, however, has wrought confusion in understanding and practice, and consequent difficulties for researchers in evaluating its efficacy, and lack of clear advice for those who would like to adopt PBL. Rather than attempting to be definitive, this Guide explores the various interpretations and practices that claim the label PBL, and critiques these against the original concept and practice. The primary aim is to provide insight into the causes of the confusion about PBL in 2008. The second aim is to point a feasible way forward so that, where appropriate, the potential of PBL as a whole-of-curriculum concept may be realised; and, where it is not possible to implement the whole concept, worthwhile educational principles that have been associated more or less with PBL may be recognised as such and given value in their own right.

Viewpoint: leaving the "empty glass" of problem-based learning behind: new assumptions and a revised model for case study in preclinical medical education

The popularity of problem-based learning (PBL) reflects medical educators' recognition that case study can enhance the preclinical medical school curriculum. However, the PBL method itself has features, particularly its reliance on small-group work with tutor-facilitators, that are expensive to implement and that limit the potential educational value of case study. The author systematically analyzes specific aspects of the PBL methodology and concludes that the PBL approach misuses the faculty, tends to compromise the authenticity of cases, and results in an unnecessarily varied and impoverished educational experience for students. Approaches to case study with different assumptions need to be devised. A model is proposed that shifts the goal of case study from development of problem-solving skills to development of ideas that allow meaningful engagement in sophisticated discussions of medicine. In this model, the method shifts from self-directed learning to independent study guided by the expertise of the faculty. One possible approach to case study based on this model is briefly described. It consists of reading published cases from the medical literature, with analysis and discussion of the cases led by faculty experts in large-group format. The approach immerses students in an authentic, state-of-the-art discussion of medicine and is easily incorporated into any curriculum structure at limited cost. The author argues that, contrary to the claims of proponents, the glass is "mostly empty" for PBL and that we can generate the higher-level discussion that case study merits only by moving away from PBL's extraneous assumptions.

The small group in problem-based learning: more than a cognitive 'learning' experience for first-year medical students in a diverse population

In problem-based learning (PBL) curricula, first-year students need to adapt to a new learning environment and an unfamiliar new pedagogy. The small-group tutorial potentially offers a learning environment where students can become self-directed learners, collaborating with other group members to achieve individual and group learning goals. At the end of the first six-week theme in a relatively new PBL curriculum, new medical students were canvassed about coping with PBL (self-directed learning; content; time management; resources) and the value of the small-group tutorial, the latter of which is currently being reported. Almost 84% of students (n = 178) responded. The benefits of participating in small groups were categorized into three domains-cognitive, affective and social-as identified from student responses. Results were analysed in terms of gender and prior educational experience (secondary school vs. prior tertiary educational experience). For almost 94% of students, the small-group tutorial provided a conducive learning environment that influenced their personal development (i.e. tolerance, patience) and socialization into the faculty. Significantly more males indicated that they had developed social skills, while more school-leavers (matriculants) than mature students felt more receptive to the views of others. More mature students claimed to have made friends. Irrespective of some conflicting opinions in the literature, the present results suggest that the PBL tutorial may be important in facilitating student socialization into a new and unfamiliar academic environment, particularly when the pedagogy differs markedly from their past educational experiences. Through interacting with fellow students from diverse origins who hold different views in the intimate setting of the small group, students felt that they had not only increased their knowledge but had also developed personally and socially. It is proposed that the small group may be useful for integrating a diverse population of students into a new academic environment.

Trends in medical education research

The medical education community is reflecting increasingly on the role and nature of research in the field. Useful sources of data to include in these reflections are a description of the topics in which we are investing our energies, an analysis of the extent to which there is a sense of progress on these topics, and an examination of the mechanisms by which any progress has been achieved. This article presents the results of a thematic review of the medical education research literature in four key journals since the turn of the 21st century. It describes four examples of areas in which the community appears to be investing its energies: curriculum and teaching issues, skills and attitudes relevant to the structure of the profession, individual characteristics of medical students, and the evaluation of students and residents. A discussion of the recent publications in these domains highlights a distinction between thematic categories of research, in which many members of the community are working on the same topic, and programmatic lines of research, in which members of the community are working together toward the shared goal of consensual understanding. The author suggests that community-level, programmatic lines of research are necessary to build knowledge and understanding of a domain and that, in the absence of such communal effort, the value of research is limited to the uncoordinated accrual of information.
