E-learning plays an important role in higher education, especially with the appearance of web 2.0. The study investigated the effects of using PBWorks, as a free web 2.0 wiki, on students' academic achievement, and students' attitudes toward collaborative learning. The study was designed as an experimental study. There was comparison between two groups. These groups were the PBWorks hybrid class environment, and face-to-face class environment. Both classes used collaborative learning. The participants in this study were 51 female students in Educational Communication Aids. Both classes had the same instructor and they studied the same material. This study was conducted in the college of education in Kuwait University. The results of the study showed that there was not a significant difference in the post academic achievement test. However, the PBWorks group made more progress than the face-to-face group when we consider the pre-test. On the other hand, the result of the students' attitudes toward collaborative learning showed there was a significant difference in the post-test in all six variables, which were monitoring working procedures, participation, monitoring group progress, helping each other, giving feedback, and the need to be monitored, and the face-to-face group had higher attitudes toward collaborative learning than the PBWorks group. Finally, one of the most important advantages of this study was that both groups had a positive increase in the academic achievement test and questionnaire that assessed attitudes toward collaborative learning.
