Which approach would be least effective in promoting student responsibility for their learning?

Limiting student choices in assignments would indeed be the least effective approach in promoting student responsibility for their learning. When students are given limited options, it can diminish their sense of ownership and investment in their learning process. Autonomy is crucial for motivation, and when learners feel they have no choice, they may engage less deeply with the material.

In contrast, engaging students in self-assessment allows them to reflect on their work and understand their strengths and areas for improvement. Providing regular feedback keeps students informed about their progress and reinforces their involvement in their learning journey. Encouraging goal-setting based on personal interests fosters intrinsic motivation, making learning more relevant and meaningful to students. Each of these approaches empowers students and encourages a proactive stance towards their education, whereas limiting choices tends to stifle their initiative and engagement.
