Western Pacific educational institutions are investing heavily in technology in classrooms to meet the needs of K-12 students. Measuring the effective use of digital technologies in the learning environment has become a routine part of monitoring and evaluating classroom instruction. One area of technology integration that has seen tremendous growth is digital game-based learning (DGBL). The researcher is interested in examining K-12 western Pacific teachers' willingness to adopt DGBL through a modified Technology Acceptance Model. This study aims to examine the extent to which teachers' perceived usefulness, perceived ease of use, and technology self-efficacy effects attitude toward adopting DGBL methods. The study will also explore teachers' perceived benefits and limitations in response to a DGBL professional development provided to them in a western Pacific school district.
