Many education institutions and teachers are recognizing and applying online learning and related educational technologies to help students achieve satisfactory learning performance. Due to the free entertainment on the Internet that may distract students' attention from online courses and with the purpose of developing students' teamwork abilities, the author in this study adopted team-based learning (TBL) and co-regulated learning (CRL) to develop students' involvement in a blended computing course. The subjects in this study were 111 first-year students from three classes taking a compulsory course titled "Applied information technology: data processing". The first group (G1, which received online TBL and CRL) and the second group (G2, which received online TBL only) were the experimental groups. The last group (CG), which received the traditional teaching method in a blended learning environment, served as the control group. The results in this study indicate that students who receive the online TBL have significantly higher involvement than those without. However, the online CRL does not contribute to better development of students' involvement in the implementation of TBL. The insights for teachers who plan to adopt e-learning, and the reasons for the ineffectiveness of CRL, are discussed in this study.
