Any training aid that an instructor uses in a lecture or demonstration must reinforce the learning objectives and:

Using training aids effectively requires that they not only support the lesson content but also align closely with the learning objectives. This alignment ensures that the aids contribute meaningfully to the instructional process. When training aids reinforce lesson content, they help clarify concepts, provide visual or hands-on examples, and engage students in a way that makes the information more accessible and easier to understand. By focusing on lesson content, instructors can create a cohesive learning experience that drives home the key points they aim to teach.

While factors such as student preferences, classroom dynamics, and instructor personality can influence how a lesson is delivered, they do not serve the primary function of ensuring that the training aids directly support the objectives of the lesson. Training aids that are aligned with the lesson content enhance comprehension and retention of the material, facilitating a more effective teaching and learning environment.
