In this study, the effectiveness of using Web Quest and collaborative learning activities to enhance the performance of EFL students in advanced grammar was examined. Participants were third-year students from the Foreign Languages and Translation faculty at Misr University for Science and Technology. The study created two groups, with 30 students in each: the control group received traditional instruction while the experimental group was presented with Web Quest and collaborative learning activities. Data was collected through pre- and post-tests on advanced English grammar, and the paired samples T-Test was used to compare the two groups' performances. The independent samples T-Test was used to determine any significant differences between the two achieving groups. The results indicated that the experimental group showed a significant improvement in performance over the control group. The study recommends the use of Web Quest and collaborative learning to boost EFL students' grammar learning results.
