Critical thinking is a skill that must be possessed by students in the 21st century and the industrial revolution 4.0 era. The Problem Based Learning (PBL) model can be used by teachers to improve students' critical thinking skills. However, teachers need appropriate learning resources to develop students' critical thinking skills. This research aims to design learning resources that are compatible with PBL models which can stimulate students' critical thinking skills. This type of research uses ADDIE. Research instruments use observation guidelines, interview guidelines, and validation guidelines. This research is resulted in the design of learning modules that are compatible with PBL models. The results of the validation from media experts indicate that the module design is very good. This design can be used as a reference in developing modules. This research can be continued at the module development stage to produce modules that fit the PBL model and can stimulate students' critical thinking skills.
