SUMMARY
The purposes of this study were to develop a blended learning model using Edmodo as a learning tool in language learning and examine the effectiveness of the model implemented in an English course regarding oral proficiency, motivation, and attitude. To achieve these purposes, a quasi-experimental design was employed to collect data using the tests and questionnaires. The samples in this study were the second-year students enrolled in an intermediate English course. The samples were from two classes, each of which contained 42 students. One class was used for the control group; another one for the experimental group. In the control group, students were only taught in a face-to-face learning environment using the PPP model whereas the experimental group studied through the PPP model in class supported by online learning using Edmodo. The findings indicate that blended learning was more effective than traditional learning. That is, students in the experimental group not only outperformed those in the control group in oral proficiency, but they also exhibited higher learning motivation. Although students in both groups did not differ in their attitude toward the PPP model, those in the experimental group expressed a positive attitude toward Edmodo. The findings of this study have implications for English language instructors, encouraging them to see how technology can facilitate learning and help learners produce better academic performance.
