This research aims to describe the validity and effectiveness of the TSTS-based electronic student worksheet on inheritance topic that has been developed to train students' analytical thinking skills. The development of electronic student worksheet used ADDIE method (Analysis, Design, Development, Implementation, and Evaluation). The validity was reviewed from the validation results carried out by expert validators using the validation sheet instrument which contains several aspects including didactic, construction, and technical requirements. The effectiveness was seen from students’ learning outcomes from pretest-posttest results, also students’ responses from filling out open-ended questionnaires after participating in the learning process. The implementation was carried out in a limited implementation to 16 F-phase students at SMAN 3 Sidoarjo. The results showed that the developed TSTS-based electronic student worksheet obtained an average score of 3.7 from the expert validator so that it was called very decent category in the eligibility criteria. Student learning outcomes data shows that all students’ learning outcomes were increasing with N-gain score > 0.70 with an average score 0.94, which means that they have high criteria for learning outcomes improvement. Student response questionnaire data that has been analyzed using the NVivo 12 produces a project map visualization that showed that the use of electronic student worksheet has a positive effect on improving students' analytical thinking skills. The TSTS-based electronic student worksheet that has been developed is valid and effective to train students' analysis thinking skills in inheritance topic, based on the results of validation, as well as students’ learning outcomes and responses.
