Final answer:
The teaching approach of describing, demonstrating, and then having the client perform an exercise is known as observational learning or modeling and aligns with Bandura's social learning theory.
Step-by-step explanation:
When teaching a client a new exercise, the approach involving description, demonstration, and then execution by the client is known as observational learning or modeling. This method is based on Bandura's social learning theory, which suggests that people can learn through observation, imitation, and modeling. Firstly, the trainer describes the correct technique, which aligns with the concept of praxis, where the client is supposed to understand verbal instructions and translate them into actions. Secondly, a demonstration of the proper movement is given so the client can visualize and understand the movement pattern. Lastly, the client is allowed to perform the exercise, applying what they've been taught and receiving sensory feedback to adjust their technique as needed.
