Covid-19 also greatly affected education. Thermochemistry is abstract and difficult to understand, so Project Based Learning (PBL) models are needed. This study developed project-based electronic student worksheets (e-SW) using the Plomp model. Validation results (Aiken?s V) were 0.88 and 0.89 (very valid). Practicality results were 89.86% (small group), 87.21% (students), and 89.03% (teachers), all in the very practical category.
