Model Knisley: Brainstorming: Berpikir Kritis

Abstrak

This study aims to examine the application of Knisley Mathematics Learning Model (MPMK) with Brainstorming Method (MB) to the achievement and improvement of mathematical critical thinking ability. The method in this research is quasi experiment with non-equivalent control group design. Subject in this research are the students of X MIPA 3 class in SMAN 2 Sukabumi as the experimental class and the students of X MIPA 4 class in SMAN 2 Sukabumi as the control class. The instrument used in this research are a description of mathematical critical thinking ability test. Data analysis of mathematical critical thinking ability using independent sample t-test through SPSS 20.0 for Windows and continued with Scheffé test use Microsoft Excel as well as questionnaire of mathematical anxiety data analysis, where data is converted into quantitative data with MSI (Method of Successive Interval). Based on the data analysis, it can be concluded that: 1) the achievement of mathematical critical thinking ability students who get MPMK+MB is better than the students who get the Ordinary Learning; 2) the improvement of mathematical critical thinking ability students who get MPMK+MB is better than the students who get the Ordinary Learning; Therefore, the MPMK+MB can be used as an alternative for teachers in implementing mathematics learning in the classroom.
