Abstract

The ability to think computationally is a new thing assessed in PISA 2022. In mathematics, Indonesia ranks 70 out of 81 countries with an average score of 366, while the global average is 472. This shows the need for improvement in mathematics learning, one of which is through learning models that support computational thinking skills. This study aims to improve students' computational thinking skills on set material using the Problem-Based Learning model by considering students' prior knowledge. This study used a pseudo-experimental method with a nonequivalent control group design. The study population consisted of 224 grade X students in Bantul High School, and the sample was taken randomly using the cluster random sampling technique, resulting in two classes with a total of 64 students. Data were obtained from pretest and posttest, then analyzed descriptively and with two-way ANOVA and effect size. The results showed that prior knowledge did not significantly affect computational thinking ability. However, the PBL model had a significant moderating effect on students' general computational thinking ability. These results indicate that the problem-based learning model effectively improves these skills.

Abstract

The ability to think critically is one of the abilities students must possess. Students critical thinking skills have not been encouraging. There is a need for learning that can improve this ability, one of which is advocacy learning. The study aims to increase students critical thinking skills with open-ended mathematical problems in advocacy mathematics learning. This study is a nonequivalent control group design with a pre-test post-test control group. Sampling using cluster random sampling, randomization was carried out in classes at Junior High School 4 Bandung by taking two classes. Data analysis used Mann-Whitney, one-way ANOVA, and Tukey. The results showed that students treated with an advocacy approach by giving open-ended questions had better mathematical critical thinking skills than those who received conventional learning. Also, students with high prior knowledge had better critical thinking skills compared to the other two groups. This research implies that the advocacy can be used as an alternative to learning mathematics for students with high prior knowledge.
