In this study we develop a framework for mathematics e-textbook analysis, based on the notion of “connectivity”. We introduce criteria to assess the different aspects of connectivity and build an analysis grid for e-textbooks. We illustrate the framework proposed by analyzing two commonly used French grade 10 mathematics e-textbooks....
