PENERAPAN MODEL KOOPERATIF STAD (STUDENT TEAMS ACHIEVEMENT DIVISION) UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS

Abstract

The purpose of this study is to learn how the cooperative delivery division model (student vocachievement division) can improve the critical mathematical ability of class iv educated at state's 019 estuary uwai kab kampar, prov. Riau. This method of research is the study of class action (PTK), with two cycles including planning, execution, observation and reflection. The stage is a alternating silkus run by similar steps and is focused on the cooperative targeting model of stad type. The subject of this study is the fourth grade student of the country 019 estuary uwai, which consists of 15 trainees. The data-gathering techniques used in the study by observing teachers and learners during the learning process and using tests of issues performed at the end of the cycle and documenting during the graduate process. The results of this study are known to be that the efficiency of the I cycle is 66% and the efficiency of the second cycle at 91.66%, where success has reached the criteria for success. Based on these results, there is an increase in the mathematical critical thinking ability of class iv students through a cooperative spending model of stad in the country's 019 estuary uwai. The suggestion of this design should be a cooperative advertising model, a type of stad being used in a mathematical coincidence because itis shown by this method could increase the critical mathematical ability of class iv educated.
