Problem-solving skills are an important basic competency in 21st-century learning through the Merdeka Belajar Curriculum. However, the problem-solving skills of students in Indonesia are still low. Therefore, an effective learning model is needed to improve problem-solving skills, one of which is through the development of teaching modules. This study aims to develop teaching modules based on Problem-Based Learning (PBL) assisted by e-books to improve the problem-solving skills of grade X high school students based on content, construct, and language feasibility. This research uses a development approach with the 4D model, which includes the stages of Define, Design, Develop, and Disseminate. However, this research only focuses on the development stage (Develop) by conducting module validation. The validation was conducted by three validators, namely educational expert lecturers and material expert lecturers. The results showed that the PBL-based teaching module to improve problem-solving skills had met the validity criteria regarding content, construct, and language. By using the mode value, a value of 4 and a validity percentage of 100% were obtained with a very valid category. Therefore, the teaching module developed is suitable for use in trials on students in the learning process to improve problem-solving skills. © Published under licence by IOP Publishing Ltd.
