A systematic review of design and technology components of educational digital resources

With the rise of the Internet and the proliferation of online content, the design and evaluation of educational digital resources (EDRs) are pressing and challenging issues. They warrant an investigation of what exactly are the features that increase the quality of EDRs. In a previous professional development program, we trained and supported teachers in evaluating and selecting EDRs with the support of a scientifically validated rubric. In this present study, through quantitative, qualitative, and text-mining methods, we analyzed the review data of 1200 resources produced that professional development program in order to provide a big picture of the quality of currently available products, and to identify the features that characterize quality digital resources. Our findings suggest the need for digital repositories to reflect or make visible how resources fit particular instructional design models.
