Which technique is NOT effective for assessing student understanding during a lesson?

The technique of ignoring student feedback is not effective for assessing student understanding during a lesson. Student feedback provides valuable insights into their comprehension and engagement with the material being taught. By actively listening to questions, concerns, and reactions from students, teachers can gauge whether the lesson is being understood or if adjustments are needed.

Conversely, the other techniques—using questioning techniques, observing student participation, and conducting short quizzes—are all active methods that promote and evaluate student learning. Questioning techniques prompt students to articulate their understanding, while observing participation captures their engagement and reaction to the instruction. Short quizzes offer immediate feedback on what students have grasped and what areas may need further reinforcement. Together, these strategies facilitate a dynamic and responsive learning environment, whereas ignoring feedback prevents any insight into the students' learning process.
