Dear Carmen Pedersen,

Research on  untangling the crucial aspects dominating  teaching strategies and their impact on the quality of learning has become increasingly important over the past few decades.  In point of fact, the specific ways in which teaching strategies drive learning has been a matter of great interest in applied linguistic research. Surprisingly,  concerned practitioners in the field of language teaching are still seeking clarity about how to develop carefully -designed instruments in order to measure the frequency and  efficiency of teaching strategies used by respective teachers. However,  we need first to specify  certain demographic information targeting secondary teachers' professional experience, attitudes, and beliefs to pinpoint the teaching strategies  they most frequently use in the  classroom context. Consequently, as these parameters change, the frequency of strategy use also changes. On this basis, by  using a  survey research and employing data collecting methods such as questionnaires, interviews , and panel discussions  addressing appropriate samples, it becomes possible to measure the most frequently used  teaching strategies  by secondary teachers.

Best regards,

Either by using observational checklist or by open or closed questionnaire..More precisely you can ask them directly in an open questionnaire then based on that questionnaire you can construct a closed questionnaire..

I asked this specific question in my dissertation research and published a related article that I hope can be of some help to you.

Best regards,

Debra
