Abstract This study aims to produce an electronic module or interactive e-module based on Process Oriented Guided Inquiry Learning (POGIL) in chemistry learning stoichiometry material to improve students^ critical-thinking skills. This type of research is a mixed method research. Qualitative methods are carried out with the Borg and Gall model RnD approach, from the e-module product development stage to the feasibility test of teachers and students. The quantitative method was conducted at the implementation stage of e-modules in learning. This research was conducted at SMAN 71, SMAN Muhammadiyah 11 Jakarta, and SMAN 40 Jakarta from November 2021 to June 2024. Product implementation used a purposive sampling design in experimental and control classes to test the effectiveness of e-module products. The results showed that the interactive e-module on stoichiometry material was feasible as a learning media. The average results of the experimental class in the pre and post tests were increased from 44.2 to 80.7. Statistical tests conducted with the Mann-Whitney Test showed a U-value of 113, a W value of 578, and a Sig or P-Value of 0.000 <0.05. The test results illustrate that learning chemistry by utilizing POGIL-based interactive e-modules makes a significant difference in students^ critical-thinking skills on stoichiometry material.
