The purpose of this study was to analyze the effects of the flipped-classroom approach in teaching mathematics using Khan Academy, an open-source learning platform, and to examine students’ views about their experiences. The experiment was evaluated in both qualitative and quantitative ways. After introducing Khan Academy environment to a group of students at a private school in Hanoi, we organized several high school mathematics teaching units. The students were then observed as they learned the material in the flipped-classroom format. The different types of assessment such as formative and summative assessment designed and integrated within the environment were analyzed in light of competency-based assessment approach. The research found that the flipped-classroom approach using Khan Academy boosted student achievement in mathematics while the diverse tests such as QCM, open-end question on the platform played a vital role in the learning process. We also found that teachers need to design additional teaching resources to better integrate Khan Academy environment into the Vietnamese classroom.
