Abstract
This study includes a scale development study to identify pre-service Science and Technology teachers' attitudes towards the constructivist approach. The studies concerning the pre-application form of the scale were implemented with 550 pre-service Science and Technology teachers studying in the junior and senior grades of the education faculties in eight randomly selected universities located in various regions. Since 68 pre-service teachers left some of the items unanswered and the consistency of the responses in the control items were low, the analyses were conducted with 482 pre-service teachers. As a result of the analyses performed, the scale consisted of two factors, one being positive and the other negative attitudes. The reliability of the factors was found to be .90 and .87, respectively, and the explained variances were found to be 28.39% and 23.88%. The total explained variance by the scale was found to be 52.27%; the Cronbach's Alpha reliability of the entire scale was found as .93; and the half-split reliability was found to be .83. Considering the analyses performed, it was determined that the scale has a valid and reliable structure and can be used in further studies.
