Engagement Theory focuses on three areas: related, creative, and donate. It emphasizes teamwork, communication, and social skills. Students must define their own projects and apply ideas to specific contexts. The theory also stresses making useful contributions. Scholars use theory to formulate research questions, design studies, choose participants and settings, define their role, collect and analyze data, and interpret and apply findings. A theory provides a systematic framework to explain phenomena, identify factors, guide research, and be tested in practical application and further studies.
