Scientific reasoning helps children understand the world around them. Teaching scientific reasoning can be challenging because not all component scientific reasoning skills develop at the same age and not all children learn these skills at the same pace. Adaptive support thus seems called for. We designed two types of adaptive instruction, based…

This paper explores students' ability to analyse and interpret empirical data as inadequate data analysis skills and understandings may contribute to the renowned disappointing outcomes of practical work in secondary school physics. Selected competences, derived from a collection of leading curricula, are explored through interviews and practical…

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum…

Identifies the problems associated with the use of dry laboratories in science education, presents design considerations for the use of such practicals in science education, and presents examples of innovative nontraditional practicals. Contains 23 references. (DDR)
