Closed-ended questions can be used to test whether students understand the basic principles underlying the learning outcomes. The use of effective open-ended questions should be used during discussions with students to gain a deeper level of understanding. Marsh (pp. 188 – 189, 2010). Petty emphasizes that questions should encourage all students to think. He goes on to say that students should be given time to answer the question asked and praised if the correct answers are given. (2009, p. 193). But traditional questions have their limitations as it can be difficult to include the entire class. Assertive questions, on the other hand, are more active and engaging for students. It is pair or group work that makes assertive questions all-encompassing. It shares students' knowledge on a topic and helps weaker students learn by doing. (Petty, 2009, p. 282 - 284). During my classroom observation I noticed that the level of questioning with students needed to be improved. Reynolds and Muijs (1999) mention that one of the main requirements to be an effective teacher is knowledge of the content taught. Spending more time reviewing content and preparing a list of questions before each lesson would go a long way in developing your level of questioning with the instructor.
