Abstract

This research aims to develop a PISA-Like mathematical literacy test based on Yogyakarta socio-culture that is valid, practical and effective. The research method used is Research and Development (R&D) with the Plomp development model. The subjects of this study were 18 students of class VIII of SMP Teladan Yogyakarta. The instruments used included validation sheets, teacher response questionnaires, student response questionnaires, and test instruments. The results of the study showed: (1) the expert validation results obtained a V-Aiken value of 0.75 with a fairly valid category, (2) There were 7 valid and reliable questions, (3) The teacher's response was very good with a score of 50.67, (4) Student responses to test questions obtained 78% of students obtained a score of 38.1 with a good to excellent category, and (5) 72% of students obtained a mathematical literacy test score with a sufficient to good category. Based on the overall data analysis, it can be concluded that the development of a mathematical literacy test instrument based on PISA-Like with the socio-cultural context of Yogyakarta is declared valid, practical, and effective for measuring the mathematical literacy of class VIII students of SMP Teladan Yogyakarta at the prediction level 3.

Abstract

This study aims to understand the students’ computational thinking skills in statistics. The type of research is descriptive with a qualitative approach. The data collection techniques in this study include 1) Tests; 2) Interviews; 3) Documentation; and 4) Validation Sheets. The data analysis in this study involves: 1) Data condensation; 2) Data presentation; 3) Verification; and 4) Conclusion drawing. The validity of the data in this study is ensured using the technique of triangulation. Subjects were selected using purposive sampling. The instruments used were two statistical problem-solving questions. The results showed that in solving the first and second questions, the respondents could address the problems using the components of Computational Thinking, starting with decomposition, abstraction, and algorithm tasks. However, the pattern recognition component was not evident in the problem-solving process, even though some respondents gave incorrect answers. This was because the respondents did not fully understand the questions. They only read the questions once or twice, so the information was not fully comprehended. Additionally, the respondents only considered the simplest path and overlooked more complex paths in solving the second question. Students can carry out abstraction and algorithmic tasks, but they still struggle with decomposition and pattern recognition.
