In this paper, we describe a classification framework which we developed and that practitioners find useful and usable in the design and evaluation of technology-enhanced resources and that incorporates factors which impact on student engagement with such resources. The classifications in the TeRMEd framework were derived from an evaluation of technology-enhanced resources, trialled within non-specialist first-year undergraduate mathematics modules. The theoretical foundation included a literature review, detailed analysis of resource trials and outcomes of the resource evaluations. Subsequently, the TeRMEd framework was evaluated by lecturers involved in the resource trials. Using the TeRMEd framework for technology integration was shown to be beneficial in terms of both design and evaluation. By carefully considering the classifications, practitioners can also encourage student engagement with resources.
