A hypermedia presentation to understand interactions between electron and solid
This paper develops some modules which help undergraduates to learn theoretical and functional aspects of characterization instruments of solids. An application is given with a scanning electron microscope (SEM) which is routinely used in many laboratories.
During the time devoted to material characterizations, students have first to learn how to used SEM, and secondly to obtain characteristic images of a subject. At any time, the CAL softwares can be used to help the students. At the end, the students have to present their observations during a poster presentation.
In this case, the application software does not replace the supervisor's action, but it increases the students' practice on a high level, expensive and single apparatus.
These applications have been created with SuperCard®. They run on the cheapest MacIntosh computers.
