Analysis of critical thinking questions on theoretical and mathematical topics found in physics textbooks.

This research has been carried out to obtain the overviews of critical thinking questions found due to theoretical and mathematical physics topics found in senior high school physics textbooks. This research is a descriptive research, in which the data was collected through observation by doing document analysis and interviews. Observation was done to physics textbooks currently used in Indonesia, i.e. physics textbooks which have passed the assessment of the national education standard body (BSNP), that are regulated by the Decree of Education and Culture Minister 148/P/2016 on Determination of the Titles of Textbooks for Specialization Courses at Senior High Schools Level. The interviews were done with teachers and students enrolled at tenth, eleventh, and twelfth grades of a senior high school in Bandung District in academic year of 2020/2021. The interviews were oriented to reveal the physics topics that are considered to be theoretical and mathematical by teachers and students. Critical thinking analysis to questions found in physics textbooks was based on the critical thinking indicators developed by Tiruneh et al (2016). Based on the data analysis, it was found that: 1) tenth grade physics topics which are considered to be theoretical and mathematical are vectors, two dimensional motion, and harmonic oscillation, 2) eleventh grade physics topics which are considered to be theoretical and mathematical are kinetic theory of gases, thermodynamics, and light, 3) twelfth grade physics topics which are considered to be theoretical and mathematical are theory of relativity, quantum phenomena, as well as atom and radioactivity, 4) the availability of critical thinking questions (CTQs) in such theoretical and mathematical physics topics found in the physics textbooks in Indonesia is relatively minimum, 5) CTQs mostly found in every physics textbook are CT questions dealing with the aspect of likelihood and uncertainty analysis, especially for indicator of predicting the probability of event, and 6) CTQs dealing with the aspect of problem-solving and decision-making were not found in all physics textbooks.
