Final answer:
Whether an instructor should demonstrate poses the entire time in classes depends on the educational goals. Live demonstrations are crucial for teaching correct postures, but students also need practice time. Symbolic modeling shows that learning can occur without a live model present.
Step-by-step explanation:
The statement "we should demo poses the whole time in our classes" can be true or false depending on the context and goals of the class. From the provided information, it appears the emphasis is on the utility of live demonstration (live model) and symbolic modeling for learning purposes, especially in physical activities such as yoga.
In some classes, continuous demonstration by an instructor is beneficial for students to learn the correct postures and movements. As indicated in Figure 6.17 (a), observing a live model can be incredibly effective for learning in a physical activity setting. However, the presence of the instructor as a model throughout the entire class might not be necessary; students also need time to practice on their own and develop self-awareness in their movements. Additionally, as shown in Figure 6.17 (b), learning can also take place through symbolic modeling, such as watching demonstrations on television or other media, suggesting that the physical presence of a model is not always required for learning.
Ultimately, the approach should balance live demonstrations with opportunities for students to engage in self-guided practice, thereby utilizing both demonstration and independent learning. This balance helps students in classes to integrate the observed techniques into their own practice, potentially improving their skills more effectively than continuous demonstration alone.
