The aims of this study are to: (1) to describe the effectiveness of the REACT strategy viewed from Mathematics Learning Achievement, Mathematics Problem Solving Ability, Mathematics Connection Ability, and Student Self efficacy of State Senior High School 4 Magelang Students, and (2) determine a more effective learning strategies between REACT strategy and conventional learning in the derivative function instruction viewed from mathematics learning achievement, mathematical problem solving ability, mathematical connections ability, and self-efficacy of State Senior High School 4 Magelang Students.This study was a quasi-experimental research. Collecting data technique are test and nontest. Analyze data technique using one-sample t-test, Hotelling's T2-test, and t-Bonferroni test. The results show that: (1) The REACT strategy is effective in derivative function instruction viewed from mathematics learning achievement, mathematical problem solving ability, mathematical connections ability, and self-efficacy of State Senior High School 4 Magelang Students, and (2) REACT strategy is more effective than conventional learning in derivative function instruction viewed from mathematics learning achievement, mathematical problem solving ability, mathematical connection ability, and self-efficacy of State Senior High School 4 Magelang Students
