The validity of learning devices with generative learning models to improve mathematical problem-solving ability

Abstract

This validity aims to determine the validity of mathematics learning tools based on generative learning models to improve students' mathematical problem-solving abilities. The validity seen is constructed validity and content validity. Construct validity is the suitability of the product that is developed with theories that are the basis of product development, while content validity is the suitability of the product developed with the established curriculum. Validated learning devices are Learning Implementation Plans and Student Worksheets class VII junior high school. This learning tool is validated by 5 Expert Experts consisting of 3 Mathematical Experts, 1 Indonesian Language Expert, and 1 Educational Technology Expert. Validity test data was obtained from the results of validation by experts using the instrument validity test sheet form questionnaire. The results of the experts' validation indicate that the learning device meets valid criteria.
