Abstract

Computational Thinking is a skill that everyone must possess, especially students, in the face of increasingly developments. Therefore, there is a need for innovation in mathematics learning integrated with Computational Thinking. This study aims to find out about the mathematic worksheets based on Computational Thinking effectiveness of the material linear equations in two variables on problem-solving ability. The population in this study was VIII class in Ambarawa 1 State Junior High School 2021/2022, the VIII-B class obtained and became the research sample through the sampling technique, namely cluster random sampling consisting of thirty-four students. Collecting data using five essay questions about problem-solving ability test, this test is given through pre-test and post-test to research sample. Statistic analysis using Paired Sample T-Test by significance level on 5% against pre-tested data using Lilliefors Test and Fisher Test. The result of pre-tested data showed that data is normal and homogeneous seen from Lcounting-pre-test (0,105) < Ltable (0,1497) and Lcounting-postets (0,122) < Ltable (0,1497) then F_counting (1,6929) < F_table (1,7878). Based on pre-test and post-test data analyzed showing that there is an increase in the average value test, from 54 up to 78,47. Effectiveness analysis showed that there is a difference between the average pre-test value to the average post-test value, by the t_(counting ) (16,198)> t_(table ) (2,034). This study concludes that the mathematic worksheets based on computational thinking (CT) are effective in increasing Student’s problem-solving abilities. Keywords: Computational Thinking, Mathematic Worksheet, Problem-Solving Ability.
