Abstract: An apparatus for creating or modifying browser-renderable teaching objects for use in creating a browser-renderable textbook data object. The apparatus includes a database, a network interface for receiving a source file containing codes for creating or modifying the browser-renderable teaching objects by way of a network, and a processor configured to create or modify the teaching objects based on the codes, and store the teaching objects in the database. A first code instructs the processor to create at least one browser-renderable section object for the textbook data object, the first code including a first attribute configured to instruct the processor to configure the at least one section object such that, when rendered by a browser module, a specified section title is provided at a beginning of the at least one section object; and (2) set of codes configured to instruct the processor to create or modify the teaching objects within the at least one section object.
