PENERAPAN MODEL GROUPING INVESTIGATION UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS MAHASISWA UMMY SOLOK DALAM MATA KULIAH EVALUASI PEMBELAJARAN MATEMATIKA

Abstract

The capability of thinking critically of the students of UMMY Solok is still low on the subject Evaluasi Pembelajaran Matematika. From the previous research on this matter, the students tended to be passive on the process of learning in class, as the impact most of the students was still not able in collecting, analyzing, synthesizing the objects of the lesson, drawing conclusion from the object of the lesson, assessing and correcting the objects of the lesson with the right argumentation, and to solve the problem on the objects of the lesson. This research is aimed at improving the capability of the students through the learning cooperatively with the model of Grouping Investment. Identification of the problem in this research is can the model of learning Grouping Investigation improve the skill of thinking critically of the students of UMMY Solok seen from the indicator of capability of collecting, analyzing, synthesizing the objects of the lesson, capability of drawing the conclusion of the object of the lesson, correcting and assessing the objects of the lesson, and the capability of solving the problem on the objects of the lesson. This research is the mixing of the action research and class action research. Before conducting the class action research, the researcher doing some actions. The action research is integrated wholly to the class action research, so that this step is believed as a continuity process. The subject of this research is the students of fifth semester with the total of 35 students. The data is collected through observation sheet, problem design, field notes, and interview. The data is analyzed by simple percentage and described by descriptive analysis. The results of the research show that the learning using the model of Grouping Investigation can improve the skill of thinking critically of the students on the subject Evaluasi Pembelajaran Matematika. The improvement is shown by 100% of the students is good at collecting the objects of the lesson, 71.43% of the students is good at synthesizing the objects of the lesson, 85.71% of the students is good at analysing the objects of the lesson, 83,71% of the students is good at drawing the conclusion of the objects of the lesson, 83.33% of the students is good at correcting the objects of the lesson, and 74.19% of the students is good at solving the problem. This shows that the model of grouping Grouping Investigation can improve the skill of think critically of the students of UMMY Solok on the subject of Evaluasi Pembelajaran Matematika.
