| Abstract |
|
Characteristic for most university chemistry curricula is the division in lecture courses, where students are supposed to learn theoretical subjects, and laboratroy courses, where practical skills are taught. An important question is how theory and practical work can be integrated.
In a research and development project we observed that first year students hardly used their knowledge of phase theory in the design and performance of distillations. A content analysis learned us that there are important contextual differences between phase theory and laboratory distillations. For instance, We decided to develop a video film in which we confront students with the boiling properties of liquid mixtures. In the video following issues are treated:
- how the composition of a mixture influences its boiling point (both for non-azeotropic and for azeotropic mixtures),
It is important to stress that the video diusplays the results of real measurements, so that it may be considered as an extension of the experiences of the students.
