Due to the huge growth in online learning, educators are demanding to use advanced software or social sites as online learning settings. However, they must consider how interaction with online course content impacts learning outcomes while using the unique features of software and social cites. Yet, understanding the effects of learner-content interaction on learning outcomes in blog-based learning environments is very few. Therefore, this study aims to investigate the effects of learner’s interaction with blog based learning content on learning outcome. Two research questions were tested, and data were analyzed using regression analysis. The results show that learner-content interaction is essential for learning output, and a significant relationship was found. A subsequent analysis showed that there is a significant relationship in learning performance between students’ subjective and objective learning outcomes.
