The presentation will be an elementary introduction to creating Math exercises in STACK (= the System for Teaching and Assessment using a Computer algebra Kernel). STACK system offers random generation of questions with wide variety of input types, e.g. mathematical expressions so that the options are not limited to multiple choice. The student’s input is automatically checked with Maxima program so that answers algebraically equivalent to the correct one are accepted. This workshop is a useful prerequisite for the more advanced workshop in which we will combine STACK with JSXGraph.
