Öz-belirlenimli Öğrenme (Hetagoji) Becerileri Ölçeğinin Geliştirilmesi: Geçerlik ve Güvenirlik Çalışması

The objective of this research was to create a reliable and valid measurement tool for measuring self-determined learning skills among university students. The research was conducted with the participation of 574 university students. In line with expert opinions and suggestions, 30-item trial form of the scale was developed. The collected data were subjected to Exploratory Factor Analysis (EFA) and a structure that explained 42.17% of the total variance was obtained. It has been determined that the Self-Determined Learning Skills Scale (SDLSS) consists of 22 items and four dimensions. In addition, as a result of Confirmatory Factor Analysis (CFA), it was seen that the fit indices of the scale were between excellent and acceptable values, and the four-factor structure of the scale consisting of 22 items was confirmed. The Cronbach Alpha internal consistency coefficient of the scale is .86, and the reliability coefficient calculated by the split-half method is .80. To determine the distinctiveness of the items in the scale, the corrected item-total correlation was calculated, and 27% lower-upper group comparisons were made. Findings from item analysis showed that all the scale items were distinctive. As a result, it can be said that the “SDLSS” developed is a valid measurement tool and will provide reliable scores in determining self-determined learning skills.
