The Effectiveness of Cooperative Learning Models Tai and Stad Type in Improving Student's Critical Thinking

Abstract

This study aims to determine the level of effectiveness of the
cooperative learning model type TAI "Team Assisted
Individulization" and type STAD "Student Teams Achievement
Divisions" as a learning model in improving the critical thinking of
elementary school students of class V in science subjects. This
experimental research was in the form of a Quasi Experimental
Design. The research design used is a quasi-experimental research
using the nonequivalent control group design pattern. This research
is an experimental research conducted at SD Negeri Polobogo 03
and SD Negeri Polobogo 02 which are located in Polobogo Village.
The research was conducted from February to March in the second
semester of the academic year 2021/2022 which was carried out in
class V. The samples in this study were obtained through probability
sampling techniques with purposive random sampling type. Based
on the research results, the effectiveness of the cooperative learning
model type TAI "Team Assisted Individulization" showed an
average increase of 28.57% greater than the cooperative learning
model type STAD "Student Teams Achievement Divisions" which
was 26.75%. Based on the results of the research hypothesis test
using the mean difference test on the independent sample t-test, it
shows that there is a significant difference between the cooperative
learning model of the TAI type "Team Assisted Individulization" and
the cooperative learning model of the STAD type "Student Teams
Achievement Divisions" in terms of ability results. critical thinking
of students in science subjects.
