This type of research is quantitative descriptive research with a one-group pretest-posttest design. This research data was analyzed based on acquiring initial and final test scores and increasing mastery of material using the average normalized gain. The data analysis showed that all students' initial material mastery ability was in the failed qualification (100%), with an average score of 21,19. This situation shows the low ability of students' initial knowledge of heat and transfer material. After applying the problem-solving learning model, students obtained an average final test score of 85.08 with good qualifications.
