Abstract

Abstract The research aims for students’ critical thinking skills enhancement through utilizing the TTW (Think-Talk-Write) instructional model in the use of pictorial riddle-aided student worksheets. This research used an experimental method with a single-group pretest-posttest design. The instrument consisted of the Learning Implementation Plan, worksheet and essay test. The research had implemented in Senior High School 1 Prambanan, Yogyakarta. The subject research used 48 students with two different groups (groups A and B). But both groups have the same treatment and the only difference is the instructor who carries out treatment in the class. Data analysis used the normality test, descriptive statistical test and Wilcoxon test. The normality test result presented that only the posttest data values for class A were normally distributed. The mean value of pretest to posttest for both classes increases significantly. The mean value of N-gain students in class A is 0.432 and class B is 0.406, which in the “moderate” category. Besides, the Wilcoxon signed-rank test result obtained sig. (2-tailed) value less than 0.05 (0.00 < 0.05). So, this research knows that utilizing the TTW model in the use of the pictorial riddle-aided student worksheet can influence students’ critical thinking skills enhancement.
