The Development of Instrument Tests to Measure Students' Computational Thinking on Number and Sequence Pattern Topics

Abstract

Mathematics learning in the 2013 curriculum emphasizes the pedagogic dimension, which aims to create active students so that they are able to develop their mindset and accustom them to finding solutions to their own problems. Computational thinking is the ability to form a frame of mind that can solve problems by forming effective and efficient solutions based on the knowledge and information obtained. This research aims to develop a test instrument to measure computational thinking on number and sequence pattern material in SMP Negeri 2 Sungguminasa that meets valid and practical criteria. This study aimed to determine the process of developing a test instrument to measure computational thinking on number and sequence pattern material in SMP Negeri 2 Sungguminasa. This research is a type of Research and Development (R&D) that focuses on the development model of B&G (Borg & Gall), which contains 4 stages: the information gathering stage, the planning stage, the development stage, the validation, and the trial stage. The subjects of the trial were students of class VIII SMP Negeri 2 Sungguminasa. The instruments used in this study were the validation sheet and the teacher response questionnaire. The study results found that (1) the validation results for the test instrument to measure computational thinking were 4,46, so they only used a teacher response questionnaire for all aspects in the very positive category with a percentage of 90,6%. It can be concluded that the test instrument to measure computational thinking on number and sequence pattern material in SMP Negeri 2 Sungguminasa meets the validity and practicality criteria.
