Abstract

The purpose of this study was to find out the validation and reliability of strategy instrument test The Firing Line with Process Oriented Guided Inquiry Learning (POGIL) Modified on the solving ability of junior high school students. The subjects of this study were 4 experts. The instruments used are RPP, LKPD, about problem solving abilities and mathematical representations. The results of the expert test using the Aiken^s Validation formula concluded that RPP 0.922, LKPD 0.924, problem solving questions 0.893, mathematical representation questions 0.896, while reliability using Anava Hoyt showed RPP 0.710, LKPD 0.730, problem solving questions 0.720, and mathematical representation instruments 0.752 with reliable interpretation tall. This shows that the results of the expert^s assessment of the RPP, LKPD, problem solving and representation instruments are feasible to use.
