More effective practical work for A-level chemistry
Distillates: David Read looks at some recent chemical education research
For most A-level chemistry students, practical work involves 'following a recipe' in what are known as expository activities. This is also the case in many university labs, although in recent years there has been a shift towards a 'problem-based learning' (PBL) approach for at least part of the practical programme in many institutions. The reported benefits of PBL include the development of transferrable skills such as team-working and communication, as well as improved independent learning. In her role as an RSC school teacher fellow, Catherine Smith has developed and evaluated a suite of PBL practical investigations to support A-level chemistry teaching.
A total of 10 activities have been developed, all accompanied by pre-lab exercises and appropriate support materials to help students tackle the problem. Each activity is based on a 'real world' context, and is intended to deepen students' understanding of the laboratory techniques involved.
David Read summarises and reviews the research.
