Teaching and learning under the credit-based system has become widespread in the higher education system of Vietnam. The assessment of learning outcomes through credit-based education not only relies on the foundational knowledge accumulated in the classroom but also evaluates the process of self-study and research of learners. Besides spending time studying and researching at the university, students are required to allocate a significant amount of time to conduct self-research and participate in group discussions to address issues related to the subject matter. Although most students demonstrate a high level of self-awareness during the learning process, there are still instances of a lack of self-awareness. Recognizing this issue, the question arises: how to guide students to apply self-research methods effectively and how to objectively evaluate the results of the self-research process? Drawing on practical experience in teaching the Computer Networking course under the credit-based system for students of the K22 cohort, belonging to the Faculty of Information Technology, Thai Nguyen University of Information and Communication Technology, the authors have conducted exchanges and proposed methods, organizing techniques, and assessment tools for evaluating the results of the self-research process of the course content, aiming to enhance the quality of education and encourage students to actively engage in the learning and in-depth research process.
