In order to increase subjective norm, we therefore propose that a more transformational management should provide a clear vision on the importance of pedagogical DLM use, as well as a realistic ICT policy, and implementation strategy in the school. Transformational management should also provide conditions that stimulate professional development. These conditions should include removing problematic issues surrounding the skills based training programs, and require teachers to keep a portfolio so that their
progress can be monitored. Such initiatives show teachers that the pedagogical use of DLMs is a serious matter in their school, which could in turn increase the probability that these teachers feel more pressured to use DLMs
