Kemampuan Computational Thinking Peserta Didik Kelas VII Dalam Menyelesaikan Soal Numerasi Materi Bilangan Bulat

Abstract

Computational thinking abilities are considered basic abilities (reading, calculating, writing) that are needed by everyone to face the problems that exist in the 21st century. This research aims to describe the computational thinking abilities of class VII students in solving numeration problems on integer material. This research is a descriptive type of research with a qualitative approach. The research subjects were 29 students in class VII.1 of SMPN 32 Palembang. The data collection techniques used are tests and interviews which contain 4 indicators of computational thinking, including (1) decomposition, (2) pattern recognition, (3) abstraction, and (4) algorithms. The results of data analysis in this study show that students' computational thinking abilities are in the medium category with an average of 56.22. Almost all students in the high, medium and low categories can produce all indicators, but with different values. The indicators that appeared most were decomposition with an average of 64.36 and abstraction with an average of 63.60. Meanwhile, the indicators that appear the least are pattern recognition with an average of 53.63 and algorithms with an average of 43.29. At the pattern recognition stage, only a few students can answer correctly and appropriately to be used in solving problems. Meanwhile, regarding the algorithm indicators, several students who brought up this indicator in their answers were incomplete.
