The effectiveness of student worksheets based on computational thinking to the problem-solving skills of elementary school students in science learning

This study aims to determine the effectiveness of student worksheets based on computational thinking in science learning on the problem-solving skills of fourth-grade elementary school students. The type of research used is a quasi-experiment, namely by using an experimental group and a control group. The experimental group is a class that uses student worksheets based on computational thinking, while the control group is a class that does not use student worksheet-based computational thinking. The sampling technique used was purposive sampling with a sample of 40 students. Data collection was carrying by giving a pretest and posttest containing several problem-solving ability questions. Data analysis was carrying by using descriptive and inferential statistical analysis. The results showed that, compared to the control groups whom did not use a student worksheets based on computational thinking, there was an increase in average test scores for higher problem-solving skills among experimental students. In addition, the results of the t-test also showed a significant difference in problem-solving ability between classes that used student worksheet-based computational thinking and classes that did not use student worksheet-based computational thinking. Thus, it concluded that student worksheet-based computational thinking is effectively able to improve the problem-solving skills of elementary school students in science learning.
