Redesigning a course along the lines of a hybrid format that blends face-to-face and online learning brings about changes in instructional practice. This paper introduces hybrid teaching that uses multiple web-based tools to supplement the students' face-to-face learning environment in a difficult situation in Thailand. In order to examine factors related to student learning achievement in the hybrid teaching course, data regarding learning achievement score, amount of participation, comfort with technology, and course satisfaction were collected from 182 students enrolled in an English course and analyzed by using correlation coefficients and multiple regression analysis. The findings indicated that students had a moderate level of satisfaction with the hybrid course and comfort with technology use, and previous experience of hybrid courses did not have an effect on their satisfaction. Student learning achievement was positively correlated with how much participation students had, but was negatively correlated with students' comfort with technology. There were no correlations between student learning achievement and how satisfied they felt with the hybrid course. In addition, an analysis of benefits and drawbacks of this hybrid course allowed teachers insights into what changes were needed when adjusting the hybrid course for language teaching.
