The Effectiveness Of Cooperative Learning Type Team Assisted Individualization Based On Constructivism Toward Ability To Think Mathematically Creative Of Student

Abstract

Abstract. Many students have difficulty and get low score in trigonometry. Some reason said this subject contains a lot
of formulas and the teachers have not used the learning system that can make students more active. This study aims to determine the effectiveness of the implementation of cooperative learning type Team Assisted Individualization (TAI)
based on constructivism towad students' ability to think trigonometry creatively. This study is an experimental study
conducted at SMA Muhammadiyah 1 Semarang. Data collection technique is student activity observation and creative
thinking ability tests of mathematical ability. The result shows classical completeness of creative thinking abilities of
students reached 85.7%. Value of creative mathematical thinking skills (KBKM) was influenced by students' activity was
78.4% and the value of Mathematical Creative Thinking Skills test experimental class was better than the control class. It
means that learning of mathematics trigonometry by applying the cooperative model type TAI constructivism based is
more effective than learning by using conventional learning models.
