“…For example, given the positive effect of teacher comments on student achievement in many studies (Cavanaugh et al, 2005;Dickson, 2005;Ferdig et al, 2005;Peters, 1999), the negative effect of this factor in Algebra II (first half) group found in this study emphasises the need for more examination of the form and content of teacher comments or feedback for more insightful explanation. It is also surprising to the authors that the number of times students logged into the LMS was found to be negative and significant on student final score in Algebra II (both first half and second half) groups, because other studies (for example, Dickson, 2005;Dietz, 2002) have found that this factor can positively predict student success in online learning. Future study can be conducted on the activities in which students are engaging each time they log into the LMS for finer explanation of these findings.…”
