Assessing understanding in biology

Abstract

This paper discusses several new assessment strategies that encourage meaningful learning and conceptual understanding in the biological sciences. Our purpose is to introduce a handful of evaluation and measurement techniques that help students assimilate well-integrated, strongly cohesive frameworks of interrelated concepts as a way of facilitating ‘real understanding’ of natural phenomena. Among these methods are concept maps, V diagrams, SemNet software, image-based test items, clinical interviews, portfolios, written products, performance measures, and conceptual diagnostic tests. Evidence suggests that these methods are most useful at highlighting ‘alternative conceptions’ and assisting students who wish to ‘learn how to learn’.
