It is observed that teacher candidates receiving education in the department of Computer and Instructional Technologies Education are not able to gain enough experience and knowledge in "Programming Languages" lesson. The goal of this study is to analyse the effects of web 2.0 technologies usage in programming languages lesson on the academic success, interrogative learning skills and attitudes of students towards programming languages. "Pre-test-Post-test Control Group Quasi-Experimental Design Model" is used as research model in this study. Participants are divided into two groups named experimental group and control group. The work group chosen from the population for this study consists of 75 students in total receiving education in the 2nd grade of Computer and Instructional Technologies Teaching Department of Faculty of Ahmet Kelesoglu, Necmettin Erbakan University in 2015-2016 academic year. "Academic Success Test" developed by researcher, "Attitude Towards Programming Languages Scale" which is adapted into Turkish by Durak (2013) and "Interrogative Skills Scale" developed by Aldan, Kandemir and Saraçoglu (2013) are used in the study. As a result of the study, it is concluded that students receiving education within the experimental group are more successful. When analysing their attitudes towards programming languages, it is concluded that attitudes of students in experimental group are more positive than that of those in control group. Analysing the effects of students using and not using cooperative learning environment developed with Web 2.0 technologies on their interrogative learning skills, it is determined that post-test grades of experimental group are higher than those of control group. According to the result of the study, a learning environment designed with Web 2.0 technologies has high-level effects on students' academic success and attitudes towards programming languages and has medium-level effect on their interrogative learning skills.
