This paper examines why teachers use digital learning materials (DLMs) in their teaching activities, with the ultimate goal of identifying interventions to help improve the adoption of such resources. The authors use a very structured and grounded approach, by applying the integrative model of behavior prediction (IMBP). They first build an IMBP-based model of DLM usage based on a large literature review, which identifies three main variables: attitude, self-efficacy, and subjective norm. The rest of the paper describes the result of a survey of more than 1,400 teachers from primary and secondary school levels to identify the relative impact of the variables on the intention of teachers to use DLMs, this intention being considered in the IMBP as the key to improve resource usage.

The results of the survey show that the three variables are of key importance, with attitude being most important, followed by self-efficacy. From the results, the authors make a set of propositions to directly act on the most important variables and ultimately improve the adoption and usage of DLMs.

I found the paper very interesting, well written, and scientifically sound, with a large section providing a literature review. Concrete measures are proposed as an outcome of the study, while limitations and future work are also described.
