Abstract
The purpose of this study was to evaluate the educational process of students in terms of fundamental principles and approaches based on the constructivist approach in Turkey. In this study, which was carried out using quantitative methods, the internal consistency coefficient of the scale developed was estimated to be high. Cronbach's alpha values ranged between α= .86 (teaching process), and α= .69 (gains), and the alpha value for the total scale was calculated as α= .75. The population of the research comprised students continuing their education in three public and three private science high schools in Istanbul. The initial number of items in the student scale was 25. As a result of the pilot test, the student scale was reduced to 19 Items. In the exploratory factor analysis of the scale used in this study 5 factors emerged. Keywords: constructivist, educational process, evaluation, high school, science, scale development.
