Project-based learning (PBL) can effectively mobilize student interest by engaging them in hands-on projects that relate to real-world challenges. This method encourages active participation, collaborative work, and critical thinking, making learning more meaningful and relevant. By allowing students to explore their interests within a structured framework, PBL fosters intrinsic motivation and enhances retention of knowledge. Moreover, it develops problem-solving skills and encourages creativity, preparing students for practical applications beyond the classroom.
