  This paper shares my journey (tools used, design principles derived and
modeling pedagogy implemented) when creating electronic books-chapters (epub3
format) for computers and tablets using Easy Java/JavaScript Simulations, (old
name EJS, new EjsS) Modeling Tool. The theory underpinning this work grounded
on learning by doing through dynamic and interactive simulation-models that can
be more easily made sense of instead of the static nature of printed materials.
I started combining related computer models with supporting texts and
illustrations into a coherent chapter, a logical next step towards tighter
support for teachers and students ,developing prototypes electronic chapters on
the topics of Simple Harmonic Motion and Gravity customized for the
Singapore-Cambridge General Certificate of Education Advanced Level (A-level).
I aim to inspire more educators to create interactive and open educational
resources for the benefit of all. Prototypes:
