The purpose of this study was to investigate the use of blogs and wikis as constructive tools in the computer courses of prospective teachers and compare them with respect to perceived usefulness, perceived ease of use, intention, self efficacy, and anxiety. Ninety-two students who were enrolled in various teacher education programs used blog and wiki for their courses. After their experiences with blog and wiki, the data were collected by administrating the instrument developed by the researchers. The results showed that students were positive to blog and wiki usage in the teaching-learning process. However they found wiki more useful. Both perceived usefulness and self efficacy variables explain 71% of blog and wiki usage. This value points to a very high and significant correlation. Perceived usefulness has been identified as the variable that could explain intention by itself at the most. (Contains 10 tables.)
