Linked tutorial teaching by teleconference and videocassette.

Abstract

A system for linked tutorial teaching involving several groups of students at different locations has been introduced successfully into the teaching resources of the University of Wales College of Medicine. It utilizes standard telephone equipment supplemented by specially prepared videocassette material. The results of an evaluation questionnaire given to students indicate that the format as currently used is very acceptable and interesting. Students feel more involved than in larger group teaching sessions and value the discussion periods. This teaching method has the potential to overcome several weaknesses in existing formal teaching programmes, especially when students are based at several sites. In particular, it minimizes travelling, allows more time for clinical experience and makes optimal use of teaching expertise. The system is being developed further to encompass postgraduate centres in Wales.

Conditional reliability of admissions interview ratings: extreme ratings are the most informative.

CONTEXT: Admissions interviews are unreliable and have poor predictive validity, yet are the sole measures of non-cognitive skills used by most medical school admissions departments. The low reliability may be due in part to variation in conditional reliability across the rating scale. OBJECTIVES: To describe an empirically derived estimate of conditional reliability and use it to improve the predictive validity of interview ratings. METHODS: A set of medical school interview ratings was compared to a Monte Carlo simulated set to estimate conditional reliability controlling for range restriction, response scale bias and other artefacts. This estimate was used as a weighting function to improve the predictive validity of a second set of interview ratings for predicting non-cognitive measures (USMLE Step II residuals from Step I scores). RESULTS: Compared with the simulated set, both observed sets showed more reliability at low and high rating levels than at moderate levels. Raw interview scores did not predict USMLE Step II scores after controlling for Step I performance (additional r2 = 0.001, not significant). Weighting interview ratings by estimated conditional reliability improved predictive validity (additional r2 = 0.121, P < 0.01). CONCLUSIONS: Conditional reliability is important for understanding the psychometric properties of subjective rating scales. Weighting these measures during the admissions process would improve admissions decisions.
