Why might an instructor avoid using an instructional aid?

An instructor might avoid using an instructional aid primarily because it may distract from the main lesson focus. Instructional aids are designed to enhance learning by providing additional support or visual reinforcement of concepts. However, if they are not carefully integrated into the lesson, they can divert students' attention away from the core material being taught. The goal of any instructional activity is to facilitate understanding and retention of information, so if an aid shifts focus or leads to confusion, it undermines the intended educational outcome. Therefore, maintaining the lesson focus is crucial, and an instructor must assess whether an aid will contribute to or detract from this objective.
