The Effect of Discovery Learning Model Assisted Based Geogebra on Mathematical Critical Thinking Abilities of High School Students
Keywords:
Discovery Learning; Geogebra Software; Mathematical Critical Thinking Ability.Abstract
This research aims to ascertain the impact of the discovery learning model assisted by geogebra software on the mathematical critical thinking abilities of first grade high school students at one of the public schools in eastern Jakarta in the school year 2023/2024. This study employs experimental research methodologies in a quantitative manner. Using a posttest-only control design and cluster random sampling as the sampling technique, the researcher implemented this research design. Class XA served as the experimental class and class X-C served as the control class for the samples that were chosen. A posttest in the form of a description test is the method utilized to collect data. This research uses data analysis techniques, namely testing the prerequisites for normality and homogeneity, hypothesis testing in the form of the t test and effect size test. From the t test data, the significance is 0,13 and the effect size test on the point estimate is 0,603, meaning that there is a large influence of the discovery learning model assisted by geogebra software at a medium level on critical mathematical thinking abilities.
