I am a teacher trying to convert from print to electronic copies of student workbooks. Currently, we prepare the workbooks in WORD and print them so that each student has her own copy. She can read and annotate text, draw diagrams and complete worksheets all in the one document. We have a website for the applets, powerpoints, podcasts etc students might use. BUT, I would like to integrate all of these into the one document, a document that will work on any device and act as a record of a student's engagement with the unit of work. Some students might like to work from a print version at school. Is InDesign and an epub format what I need? Thanks.
