Abstract : The lack of teaching material on Newton's law of gravity that contains creative problem solving models that can improve problem-solving skills. This study aims to describe the validity of the teaching material. The method used is research and development with the ADDIE model. The research design is pre experiment design (the one group pretest-posttest design). The subjects of the trial, namely 17 students of class X MIPA 2 SMAN 1 Amuntai. The data collection technique was obtained through the instrument of validity of teaching materials which were validated by 2 academic experts and 1 practitioner expert. The data analysis technique is calculated by averaging the total score for each aspect assessed and the reliability of the validation results is calculated using the Cronbach-Alpha formula. The results showed that the validity of the teaching material with an average score of 3.45 categories was very valid with a reliability of 0.79 good categories, so that the teaching material of Newton's law on gravity through a creative problem solving model to improve problemsolving skills was declared valid for use in learning.
