Based on classroom demonstration experiment, college physics teaching reform is carried out. First, according to the content of college physics teaching, a college physics demonstration experiment project library is constructed by modules and chapters. Combined with all aspects of BOPPPS teaching, demonstration experiment is integrated into classroom teaching to promote curriculum reform and realize participatory learning. Specific measures include: using demonstration of physical phenomena to introduce new lessons and stimulate interest; using demonstration experiments to establish abstract physical concepts and break through difficulties; using group experiments to explore, summarize, and induce physical laws, achieving deep-level interaction; reserving military case problems or academic competition questions in the post-class test link, encouraging students to solve practical problems through experimental exploration, setting up a “five-minute physics” activity to showcase and exchange learning outcomes, achieving the goal of applying what has been learned. The teaching practice shows that the teaching reform of “BOPPPS+ demonstration experiment” enhances the interest and challenge of the course, improves the students' scientific literacy and innovation ability, and promotes the construction of the teaching team and personal development.

According to the war-oriented requirement of college physics course in military academics,this paper updates the database of physics military application cases and adopts relevant demo experiments so as to contribute to teaching under combat situation. Improving teaching via competition,the course integrates the concept and mode of discipline competition into actual teaching, and forms the teaching model of military application case in college physics, i.e military application case-experimental exploration-theoretical analysis-problem solving-expansion and improvement,with the purpose of improving the ability to analyze and solve issues under combat situation by applying physical knowledge and theories. A SPSS analysis of the survey of learning self-efficacy suggests that this teaching reform practices which is guided by war and promoted by competition plays a significant role in improving cadets' learning self-efficacy,especially in self-efficacy concerning the ability to learn.
