Final answer:
Encouraging students to take risks and try new strategies is an example of providing the optimal level of challenge from competent supportive behaviors. Giving students tasks that are too easy or too difficult and providing step-by-step instructions and guidance are not examples of providing the optimal level of challenge.
Step-by-step explanation:
An example of providing the optimal level of challenge through competent supportive behaviors is encouraging students to take risks and try new strategies. By doing so, students are pushed out of their comfort zones and are given the opportunity to grow and learn from their experiences. This approach helps them develop problem-solving skills and resilience.
On the other hand, giving students tasks that are too easy or too difficult does not provide the optimal level of challenge. Tasks that are too easy may lead to boredom and lack of engagement, while tasks that are too difficult may result in frustration and discouragement.
Providing step-by-step instructions and guidance is another example of competent supportive behaviors. This allows students to understand the process and build confidence as they work through the task.
