Özet

In this study, it was aimed to develop a scale to determine the attitudes of students towards problem based learning. Data was gathered from two groups of students; the first group being comprised of 761 students from four medical schools and the second group being comprised of 810 students from one medical school. In the study, item-total correlation and difference of lower-upper group means based item analysis technique, t test, Kruskal Wallis analysis as well as factor analysis was used and Cronbach alpha coefficient was calculated. The reliability of the scale was found to be high (alpha = 0.95). In addition, the scale's ability to distinguish students with different attitudes was found to be statistically significant (p<0.001). In factor analysis of both studies, positive and negative items of the scale were found. to assemble in two separate dimensions and to explain the major part (61.32% in the first study, 58.87% in the second study) of the scale's total variance. The results of the study indicate that the scale has good psychometric properties.
