Pengembangan Modul Ajar Pembelajaran Berdiferensiasi dengan Strategi REACT untuk Mengembangkan Kecakapan Numerasi dan Disposisi Matematis Peserta Didik

Abstract

This study aims to produce differentiated learning teaching modules with REACT strategies that are valid, practical, and effective in learning Mathematics on Statistics material. The type of research used is development research. The development procedure is carried out using Four-D steps with simplification into three stages which include define, design, and develop. Product validity is determined based on expert judgment. The practicality of the product is determined based on the responses of students and the results of observations of fellow teachers on the application of learning in class. Product effectiveness is determined based on the achievement of learning outcomes and the level of students' mathematical disposition. The results of the study show that the teaching modules developed: (1) have a very high level of validity with an average score of 4.65; (2) it is practical with an average score of student responses of 4.63 and an average score of observations of fellow teachers of 4.52; and (3) effectiveness is shown by the average score of learning outcomes assessment of 81, the percentage of completeness is 78% and the average score of mathematical disposition is 4.29.
