Daftar Isi:
- The aim of this research was to find out the influence of discovery learning model toward students’ critical thinking ability. The research design was pretest-posttest non equivalent. The samples of this research were the students of class VIID and VIIA SMP Kartika II-2 Bandar Lampung who were chosen by using purposive sampling. The quantitative data were obtained from the average score of pretest, posttest and N-gain which was tested by using T-test and U-test. The qualitative data were the students learning activities which were analyzed by descriptive analysis had an increase viewed from the average of N-gain of experiment class was 57,08. It is significantly different from control class was 25,33. The average of increase of students’ activity from the indicator of giving a simple explanation, building the basic creativity, giving further explanation and concluding had high criteria.
