摘要:In addition to traditional teaching methods, project-based teaching method has been introduced to catch up with the modern trend in education in the world towards improving students' self-learning capacity. By understanding the principles of project-based teaching teachers will have more opportunities to promote the self-learning of students, thereby making teaching activities more plentiful and practical. Therefore, in this research I aim to enhance the capacity of Mathematics self-studying of high school students through learning projects. This research was done through studying documents related to capacity and Mathematics self-study ability. In addition, in order to evaluate the results of mathematics self-study capacity of high school students in Vietnam I and the teachers involved in the project designed the assessment tool set including self-studying ladder levels, and a self-assessment note. Fourteen 10-grade students were randomly selected to participate in the project. Research results: The learning project has improved the efficiency, confidence and interest of students in solving practical problems, nurturing creative talents. Students increase their self-study ability. In addition, this study is the basis for teachers, educational researchers and curriculum developers to implement a constructive approach in enabling students to understand the relationship between theory and practice, then improving students' self-studying ability.
