• A. Action research
• B. Achievement test
• C. Text as a Vehicle for Information
• D. Text as a Stimulus for Production

Answer: (A)

Action research is a development tool for teachers that involves studying one’s own classroom practice to improve student learning. It relies on gathering data directly from the class to understand what’s working and what isn’t. Using interviews, case studies, and questionnaires fits this approach perfectly because each method provides different angles: interviews capture personal insights and experiences, case studies illuminate how teaching and learning unfold in specific situations, and questionnaires offer broader, systematic input from many students or colleagues. The whole process is cyclical: plan a change, implement it, observe the effects, and reflect to refine the approach. This data-driven, reflective cycle is what distinguishes action research as a professional development method for teachers. By contrast, an achievement test measures student performance, not the teacher’s practice; texts used as information or as production prompts are about materials and pedagogy, not about collecting classroom data to drive improvement.
