<![CDATA[Chemistry learning requires electronic student worksheets that support conceptual understanding, mathematical reasoning, and problem-solving skills. This study aimed to develop an electronic student worksheet (E-LKM) based on the Search, Solve, Create, and Share (SSCS) model for chemical equilibrium for Grade 11 at senior high schools, Islamic senior high schools, and equivalent institutions and to evaluate user responses to the developed product. The study employed a research and development method using the ADDIE model, limited to the analysis, design, development, and formative evaluation stages. The product was developed using the Liveworksheets platform by integrating the Search, Solve, Create, and Share stages. The study participants included two subject-matter expert validators, one media expert validator, two chemistry teachers, six students in one-to-one trials, and 20 students in small-group trials. Data were collected using validation forms, teacher and student response questionnaires, and the results of students’ work on the E-LKM. The final validation results showed assessment percentages of 96.12% for the subject-matter experts and 100% for the media expert, both of which fell within the valid category. Teacher responses reached 98.26%, and student responses reached 93.13%, each classified as very good. The one-to-one trials yielded a mean completion score of 94.83 and a mean completion time of 49.88 minutes. These findings indicate that the SSCS-based E-LKM on chemical equilibrium meets the validity criteria and has received very good user responses. This product provides an alternative electronic teaching resource for chemical equilibrium instruction, but its effectiveness still needs to be tested through implementation on a broader scale.]]>
