Development of A Guided Inquiry Model Mathematics Learning Tool to Improve Students' Analytical Skills in Social Arithmetic

This study aims to develop a guided inquiry model of mathematics learning tools to improve students’ analytic abilities in social arithmetic material. The study used the Research and Development (R&D) method with a 4D model that includes the define, design, develop, and disseminate stages. The developed tools consist of a user manual, teaching modules, LKPD, and test packages. The trial subjects were 28 seventh-grade students of SMP Negeri 14 Jember. Data were obtained through validation sheets, observations of learning implementation, observations of analyticity behavior, student response questionnaires, and pretest and posttest tests. The results showed that the learning tools met the valid criteria with an average validity score of 3.72–3.85, practical with an average implementation score of 3.33, and effective based on classical completeness of 82.14%, a high category of N-Gain increase, good category of analyticity behavior, and positive student responses of 89.7%.
