In the current educational research, it is crucial to investigate how to reasonably and effectively use teaching methods to complete classroom teaching tasks. The problem-based learning method, which takes “problems” as the carrier, creates problem situations, raises problems, analyzes problems, and solves problems, which is more effective for implementing teaching. This paper reviews the applications of PBL in science teaching in China’s senior high schools in recent years. The findings of the thesis are the following: 1) PBL teaching mode not only stimulates students’ learning interest and initiative but also improve students’ abilities to analyze and solve problems. 2) PBL teaching method improves students’ language expressive abilities. 3) adopting PBL teaching method can improve students’ critical thinking. Nevertheless, in the process of using PBL there are some shortcomings. From the perspective of most teachers, they are influenced by the traditional teaching mode so it is difficult for them to use PBL. Due to the limited teaching time, the assessment mode of PBL is too simple. Therefore, this study put forward some suggestions to improve PBL classes. First, teachers should look for the life phenomena related to the subject and find some teaching materials. Second, schools need to provide experimental equipment to encourage students to practice. Third, teachers should design questions with difficult coefficients to inspire students’ thinking. This paper objectively summarizes the examples of PBL science teaching in Chinese high schools, analyzes the advantages and disadvantages, and puts forward suggestions for improvement, which is conducive to promoting teachers’ thinking about PBL science teaching and promoting the applications of PBL teaching mode in Chinese high schools’ science classes. |
