(1) Oral questions
Oral questions refer to the method of asking trainees questions during class. This way, you can measure the degree of understanding of what you have taught on the spot and know whether to proceed as planned or to provide additional instruction, which enables prompt decisions on the development of the class. For this purpose, it is necessary to decide what to ask when making a class plan.
Oral questions have another advantage of making the class lively by adequately mixing questions into one-way explanations as is the case of lectures.
