Responding to questions allows students to practice recently acquired knowledge. Questions can help students become aware that they do not really understand something. If questions are followed by information about the correct response, they should have direct instructional effects, increasing motivation to learn from subsequent sections of the lecture. Questions that require students to respond may heighten their attention during a lecture. Questions that act as a diversion can reduce the rate of the delivery of new materials and allow more processing time of older materials.
Questions can force students to review all of the information that the teacher has presented.
After a week of asking a higher number of questions before, during, and after a lecture, I noticed that students were slightly more attentive to what was going on in the class. Most students attempted to answer whether right or wrong. I consulted several books on the subject of questioning to help me learn how to better deal with students who gave wrong answers. I wanted my students to not be afraid to give answers whether right or wrong. I wanted everyone to feel comfortable during the questioning sessions.
