Effectiveness of guided inquiry based on blended learning in physics instruction to improve critical thinking skills of the senior high school student

This research is aimed to determine the effectiveness of guided inquiry based on blended learning to improve critical thinking skills of students on optics subject matter. This research was conducted in SMAN 1 Bolo in Bima, NTB. The samples include 70 students of 11th class of senior high school who selected by cluster sampling technique. The research method used quasi-experimental with pretest-posttest control group design. The data of students critical thinking obtained by test and be analyzed by analysis of variance. The result of data analysis showed that p-value score < 0.05. This result indicates that the guided inquiry in physics instruction effective to improve student critical thinking on optics subject matter.
