Blended learning is a hybrid of traditional face‑to‑face and
different types of online learning services. Blended learning offers
synchronous and asynchronous learning experiences that combine the
conveniences of online courses while maintaining in‑person contact.
Blended learning addresses the needs of students who are unable to
attend classes entirely, but who nonetheless demand opportunities
for personal interaction. The appropriate instructional content
design becomes one of the crucial components to support the success
of blended learning activities. This study proposed the development
and practical use of document‑based rich and interactive content in
EPUB3 to provide an exciting instructional content model. EPUB3 is a
digital publishing standard with prosperous features and flexible
implementation that is widely accepted in academic and industry. The
EPUB3 digital book content was integrated into a Moodle learning
management system to support synchronous and asynchronous blended
learning environments. A questionnaire was applied to find out the
learners' responses and involved 155 undergraduate students at The
State University of Malang, Indonesia. The questionnaire results
showed the developed content model was feasible and suitable to be
implemented in a blended learning environment. Students seem
interested and enthusiastic about being involved in various learning
activities that add new experiences.
