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

This study aims to determine the results of the assessment of students' spatial abilities which are very important to master to understand geometry relations, and geometry properties, and solve mathematical problems including on the material of flat-sided spaces in class VIII. This research uses descriptive research through qualitative and quantitative approaches. The sampling technique in this study used a random sampling technique with 31 students as the research sample. The research instruments used were observation and interview guidelines with qualitative analysis and spatial ability tests with quantitative analysis. The analysis of the test instrument was processed with the help of SPSS and Microsoft Excel to determine the feasibility of the instrument. Based on the results obtained through several aspects of the assessment of students' spatial abilities seen from four indicators of ability. The concept understanding indicator has increased until the last meeting, while the pattern recognition and imagination indicators tend to increase and decrease at the last meeting. The interview results also prove that the spatial ability test instrument given for five meetings is quite helpful in understanding the flat-sided space building material
