Shapiro-Wilk test was used to see whether attitude scores and grades were normal. While unpaired t-test was used for comparing attitude scores of pretest and posttest; Wilcoxon signed rank test for two dependent group comparison was used to compare grades of both exams, and scores obtained from the sample question, with a significance level of 0.05. Results: The Cronbachs Alpha Coefficient was 0.67 for pretest, 0.68 for posttest; the scale has a high reliability. The students attitude points increased at the end of the year, comparing the pretest and posttest attitude scores, a statistically significant difference was existed (p=0.019). There was no significant statistical difference between the grades of both exams (p=0.097) and the sample question (p=0.482).
