It is virtually impossible to control all the factors involved in even if we know【M7】______ how to identify them in the first place, particularly such factors as motivation, previous knowledge, aptitude, learning outside the classroom, teacher performance. Consequently the conclusions to be drawn from such experiments can, with confidence, be generalized to other【M8】______ teaching situations. The results are, strictly spoken, only valid for the【M9】______ learners, teachers and schools in what the experiment took place.【M10】______
