Old wine in new skins: customising linear audio cassettes into an interactive CDROM format

An audio cassette from the Educational Techniques Group Trust’s ‘Chemistry Cassettes’ series entitled ‘Entropy – the driving force of change’ has been adapted from a linear format into an interactive CDROM format. Details of this process are described together with a student evaluation process of this topic. The results of the evaluation were encouraging in terms of acceptance by the students and their performance for the numerical parts of the topic, though difficulties with the abstract aspects were still encountered. It was encouraging that a large number of students asked that more topics from the ‘Chemistry Cassettes’ series should be produced in interactive CDROM or on-line format.
