This study uses an action research approach to investigate how different modes of pre-laboratory preparation contribute towards a fruitful laboratory experience for first year students on an access programme. We considered the experience to be fruitful if the students successfully acquired procedural understanding, communicative competence and were able to apply the conceptual understanding to make the purpose of the labs meaningful. A group of students was observed by participant observers during 1996. Data was gathered during laboratory sessions and from written pre-laboratory work. These data were analysed and changes were instituted in the running and conceptualization of the laboratory in the subsequent year. A group of students was again observed and data collected. Two important factors emerged from the analysis of the data. One finding was the importance of adequate student preparation for the laboratories, regardless of the mode of preparation employed. Another was that the ability to prepare depended on the conceptual and procedural understanding of the laboratory as a whole. Preparedness is also important if conceptual benefit is to be obtained from the practical experience.

... However, some techniques are best illustrated by video and students find this a very useful way to construct a clear idea of what they will need to do in the laboratory. Some first year students have a very limited experience of glassware and general laboratory apparatus and seeing, for example, how to set up a Büchner filtration gives them confidence and saves them from having to ask a demonstrator who is then free to engage in much more productive activities with the students such as in-lab assessment (Rollnick et al., 2001b). Also contained within the DLM is a library of online tutorial material (much of it interactive) to assist students in their understanding of a range of analytical and spectroscopic techniques which they encounter in the laboratory. ...
