Abstract: Â This study aims to determine the problem-based learning-based digital pocket book to improve problem-solving skills that reach the level of validity, practicality and effectiveness. This research method is research and development using 4-D models (Four-D Models) by Thiagarajan. The research subjects were students of class VIII SMP Negeri 12 Pontianak totaling 32 students, experts, and teachers. The instruments used in this study were validation sheets, questionnaires, and posttest questions. Based on the research results, the results of the validation of digital pocket books based on problem based learning to improve problem solving skills have a percentage of 90.44% with very valid criteria. The level of practicality of problem-based learning-based digital pocket books to improve problem-solving skills is classified as having a very practical level with a percentage of 88%. In addition, for the results of the effectiveness level of problem-based learning-based digital pocket books to improve problem-solving skills, the posttest average result is 81% with effective criteria. Thus, it can be concluded that the problem-based learning-based digital pocket book to improve problem-solving skills developed can be used because it meets the criteria of very valid validity, very practicality, and effective effectiveness.
