Final answer:
To stimulate interest and involvement when presenting a new assignment, it's important to include motivational elements, create a respectful environment that supports student control, and offer engaging, purposeful tasks.
Step-by-step explanation:
Presenting a new assignment in a way that stimulates interest and involvement typically includes adding motivational elements. These elements foster an environment where students feel respected and in control, leading to increased intrinsic motivation. Activities should not only provide a challenge but also be achievable and come with a purpose, making the tasks more engaging. Implementing these approaches, rather than strict, teacher-centered methods, encourages a more inclusive and collaborative learning experience, as exemplified by the Criminal Law professor in the provided scenario, who favors discussions, debates, and a research project over intimidating questioning and an emphasis on exams.
