  The e-book market is currently in a strong upswing. This research study deals
with the question which practical uses the e-book format EPUB3 offers for
(higher) education. By means of a didactic content analysis, a range of
interactive exercise types were developed as a result of conversations with
teachers. For this purpose, a didactic and technical concept has been
developed. Different kinds of exercises were prototypically implemented in an
e-book. Finally, a brief overview reflects the present state of the current
e-book readers. A subsequent discussion illuminates the strengths and
weaknesses of the format. In summary, it can be remarked that EPUB3 is suitable
for a variety of different exercises and that it is able to serve as a basic
format for forthcoming digital textbooks. Furthermore the openness of EPUB3
will assist Open Learning and Teaching in a meaningful way.
