BOPPPS is a student-centered, goal-oriented modular teaching model. Applying the BOPPPS teaching model in the instruction of free fall motion can guide students to actively participate in the learning process through a series of investigative activities, thereby increasing classroom engagement and fostering the development of students’ core physics competencies. Concurrently, with clear and specific learning objectives as a guide, students can participate in the classroom in a targeted manner, thereby enhancing teaching effectiveness.
