To write a research question, start by reflecting on your teaching experiences and identifying areas where you seek improvement or deeper understanding. Consider what aspects of student learning or instructional strategies intrigue you. Next, conduct a brief literature review to understand the current state of research in your area of interest and identify any gaps or unanswered questions.

For instance, if you are interested in the impact of active learning strategies on student engagement, your research question might be: "How do active learning techniques influence student engagement and academic performance in undergraduate biology courses?" This question is specific, clear, and researchable within a classroom setting. 

Another example could be: "What are the effects of formative assessment on student motivation and learning outcomes in college mathematics?" This question addresses a specific teaching strategy (formative assessment) and its impact on student motivation and learning, making it feasible for a classroom-based study.
