Abstract

The study aims to see the effect of the application of discovery learning model in improving the ability of critical thinking mathematically and students self-confidence. The population of this research is high school students in East Bogor Regency. The sample of the research is the students of 10 th grade Science Major from 116 students. This research is a quasi experimental research with pretest and postest control group research design. The instrument used is a matter of mathematical critical thinking and self-confidence questionnaire test. Data analysis was performed on the normalized gain level between the two sample groups. The result of this research are (1) There is an improvement of mathematical critical thinking ability of students who are treated with discovery learning model is better than students who get conventional learning; (2) There is an interaction between learning model and early math ability (KAM) to improving students' mathematical critical thinking ability; (3) There is an improvement of mathematical critical thinking ability in students with high KAM; (4) There is no improvement of mathematical critical thinking ability in students with low KAM; (5) Increased self-confidence of students who are treated with discovery learning model is better than students who received conventional learning; (6) There is an interaction between learning model and math early ability to increase student self-confidence; (7) There is an improvement of self-confident in students with high KAM; (8) There is no improvement of self-confidence in students with low KAM.
