E-books are widely used as an important resource in learning. The most common way to use e-books is to incorporate them while a learning interaction is in progress. However, some learning styles are better supported inversely: e-books take the lead and are used to initiate and bind learning communications to the topics in focus. Unfortunately, existing e-book formats cannot accommodate this need effectively, potentially causing learning interactions to lose grip on the intended discussion framework. Inability to bind a conversation with the materials in the first place can also introduce overhead cost to the readers due to the burden of bringing the materials into the discussion. In this work, we add the capability of e-books to serve as an interaction platform. An e-book is considered as a collection of objects indicating topics of learning discussions. Asynchronous conversation is anchored to one or more topic, and defined by a context that specifies participants and communications among them. Communication is modeled after a reactive mechanism by using event-action pairs. The proposed framework also accommodates dynamics within discussions, as well as structured discussions commonly found in many learning environments.
