The Effect Of A Realistic Mathematics Approach On Students' Mathematical Critical Thinking Ability

Abstrak

This study aims to determine the effect of a realistic mathematical approach on students’ mathematical critical thinking skills in the flat-sided geometry material at SMP Negeri 1 Stabat. This reasearch is a quantitative reasearch, with the type of experimental research. The population is all class VIII students, totaling 118 people. The sample used by the reasercher is class VIII-1 and class VIII-2 with 30 students each to serve as an experimental class determined by purposive sampling technique. Data collection techniques  by  giving  pre-test  and  post-test  to  determine  students’  ability  to  think critically mathematically. The data analysis technique in this reaserch is using hypothesis testing. Reseach hypothesis testing using t test. Based on the results of the research and hypothesis testing, the researcher can conclude as follows: (1) There is a significant effect on the t test, namely t count > t table with t count = (7.330) and t table = (1.669). it can be concluded that there is a significant effect of the realistics mathematics approach on students’ mathematical critical thinking skills in the flat-sided geometry material at SMP Negeri 1 Stabat.
