Abstract
Physics learning in the class has not been able to improve student^s 21st skills due to the learning process still focusing on teachers and the lack of using innovative and variative teaching models. Critical thinking skill is one of the 21st skills which will be analysed in this study after utilizing the Inductive learning model by assisting student worksheet towards Student^s critical thinking skill. This study employed a quasi-experimental with non-equivalent control group design at State Senior High School in Kupang, Nusa Tenggara Timur, Indonesia. The research subjects consisted of 26 students on experimental class and 29 students on control class. Student^s critical thinking skill was measured through 7 essay question items which had been measured their validity and reliability on the Optic Tools of 11th grade students. The data were firstly analysed by Bartlett^s test and Chi Square test to show that they were qualified for further test. Furthermore, the hypothetical test results were conducted by comparing n-gain values of student^s critical thinking skills before and after conducting inductive learning model with student work sheet which were different. Therefore, it seems that the application of the model on experimental class could effectively and significantly enhance student^s critical thinking skills.
