This study aims at developing worksheet on problem-based chemical bonding material to determine quality, critical thinking ability and learning outcomes on the worksheet. Research and development (R & D) was used in this study. The population in this study were all students at X science class at senior high school Banda Aceh, Indonesia in 2018/2019 academic year. Sample selection in this study was done using random sampling with students at X science2 class and X science3 class. Data were analyzed using N-Gain test and t-test after the test showed that problem-based worksheet can improve student’s critical thinking skill (CTS). This can be seen from the N-Gain value from each indicator with the high category; and it was also strengthened with the Z test on each t-test indicator that showed the value of ttest = 5.08 and t table = 1.68. It can be concluded that there are differences of the increase students’ learning outcomes between experimental class and control class through the development of problem-based worksheet on chemical bonding material.
