Intermediate Chinese Conversation is an elective course offered by the Department of Chinese Studies for second- and third-year students at our university. It aims to help students learn basic sentence structures and grammar, familiarize them with intermediate-level Chinese conversational expressions, and naturally engage in everyday Chinese conversations. Most class activities involve speaking, but there are difficulties, such as students being relatively passive in class and not actively presenting. Using class models presented in previous literature, the present study develops a problem design, teaching-learning activity design, process evaluation, and outcome evaluation for Intermediate Chinese Conversation. By applying this design in class, this study identifies the differences between the traditional lecture-centered method used before and the new teaching method used after four weeks. It shows that the latter method — PBL helps students learn Chinese conversation more effectively. In conclusion, this study effectively tackles two issues: First, it encourages students to adopt an active learning attitude. Students who were previously not interested in Chinese conversation classes and were left out began to take interest in the class using the PBL method. Second, it helped enhance students’ problem-solving ability. Through group activities, students collaborated with each other, reaffirmed the value of working together, and sufficiently solved the problems given to them.
