Constructivist,Problem-Based Learning Does Work: A Meta-Analysis of Curricular Comparisons Involving a Single Medical School

Effects of problem-based learning as reported in curricular comparison studies have been shown to be inconsistent over different medical schools. Therefore, we decided to summarize effects of a single well-established problem-based curriculum rather than to add up sometimes-conflicting findings from different problem-based curricula. Effect sizes were computed for 270 comparisons. The results suggest that students and graduates from the particular curriculum perform much better in the area of interpersonal skills, and with regard to practical medical skills. In addition, they consistently rate the quality of the curriculum as higher. Moreover, fewer students drop out, and those surviving need less time to graduate. Differences with respect to medical knowledge and diagnostic reasoning were on average positive but small. These outcomes are at variance with expectations voiced in recent contributions to the literature. They demonstrate that constructivist curricula can have positive effects on learning even if they deemphasize direct instruction.     

Test “Oppression” and Recovery

How can we avoid the "why new teachers cry" phenomenon and the high dropout rate for beginning teachers? Start teacher preparation with an introductory foundations class that is experience based and allows students to study themselves and their preferences for teaching styles, learning styles, and classroom management by living through case studies of sample lessons and classroom simulations. The author describes the nature of the course and presents research showing the effectiveness of the course for five academic years: 2000-1 through 2004-5.     

Assessment of attention in school children: teachers' ratings related to tests of attention

The paper provides (1) a teacher-administered rating instrument for inattention without confounding the rating with hyperactivity and conduct disorder, and (2) evidence that the ratings correlate with the scores obtained from cognitive tests of attention. In Study I, the first objective was to investigate the construct validity and the inter-rater reliability of the Attention Checklist (ACL) by factor analysing the teacher ratings of 110 Grade 4 children, obtained by using the ACL. The second objective was to investigate the predictive validity of the ACL by examining the relationship between the scores obtained for the participants from teachers' ratings using the ACL and the scores obtained by participants in the lab-type attention tests. The results of factor analysis showed that a single factor labelled ‘inattention’ underlies the 12 items in the ACL. Examining the differences in performance on attention tests, the ‘low attention’ children as rated by the teachers on the ACL scored lower than the ‘high attention’ children on the objective tests of attention. These findings were replicated in Study II, which was conducted to test further the construct validity and predictive validity of the ACL. This time, only those two tests (Auditory Attention and Visual Attention) that had shown relatively poor discrimination between the high and low attention groups in Study I were, again, administered to another cohort of 97 Grade 4 children, as it was our intention to further challenge the reliability of the ACL. Overall, the results of both studies suggest that comprehensive assessment of attention skills should include both ACL and objective measures of selective attention.     

The semantics of 'truth': a counter-argument to some postmodern theories

This article reviews a number of claims made by postmodernist writers on the education of adults, who deny the existence of objective truth. It is argued here that such claims are asserted without supporting evidence and that they fail to take into account the semantic structures of language and actual linguistic usage. The article tries to show that analysis of semantic structure reveals a concept of truth embedded and presupposed in language and that truth and meaning are interrelated.     

Distance education for the gifted and talented: An interactive design model

In 1994, the New South Wales Board of Studies, Australia, introduced three high level Distinction Courses for gifted and talented students: comparative literature, cosmology, and philosophy. All are offered by distance education but the cosmology course employs an interactive design model and an extensive communication system that differentiates it from the other two. This article explains the model and the way it is used in practice to organize, sequence and deliver the course. Discussion addresses ways in which the model might be used to design a wider range of courses for gifted and talented students.
