What technique should an instructor use to ensure proper habits and correct techniques during training?

The building-block technique is particularly effective for ensuring proper habits and correct techniques during training because it systematically introduces skills and concepts in a progressive manner, starting with foundational elements and gradually increasing complexity. This approach allows learners to master each building block before advancing to more challenging tasks, thereby reinforcing correct techniques and encouraging the development of good habits.

By using this method, instructors can help students understand and apply fundamental principles, which are essential for more advanced skills. It also allows for continuous reinforcement and correction, ensuring that mistakes are addressed early in the learning process, which is crucial for skill retention and confidence.

In contrast, while the other methods like feedback technique, interactive learning, and collaborative learning have their own merits, they may not focus as deliberately on the gradual skill accumulation essential for developing proper techniques. Feedback techniques aim to refine skills through guidance, interactive learning emphasizes participation and engagement, and collaborative learning promotes teamwork and shared knowledge, but none of these necessarily structure the learning process in the step-by-step manner that the building-block technique does.
