As the popularity of mobile technology rises, there is an increased emphasis to integrate these devices into the classroom. While some research has investigated its effectiveness, further research is needed to understand why teachers adopt these tools to improve teaching. Using the Unified Theory of Acceptance and Use of Technology (UTAUT), this formative assessment used an explanatory mixed-methods approach to identify the barriers and challenge teachers face in adoption. Themes of the qualitative data focused on self-engagement and self-directed learning, classroom management challenges, self efficacy and limited professional development, and lack of clear administrative vision. Implications for practice are also discussed.
