The Development of Cooperative Learning Tools with Teams Games Tournament (TGT) Types to Overcome Students’ Mathematical Anxiety in Algebraic form Material for The Seventh Grades of Junior High School Students

This research was aimed to (1) describe the development the good cooperative learning tools with TGT types on algebraic form material and (2) know the effectiveness of the learning on algebraic form material using TGT to reduce the students’ mathematical anxiety. This research was a development research. Development model of the equipment in the current research was an ADDIE, involving Analysis, Design, Development, Implementation, and Evaluation. The subjects of this research were seventh grader of SMP N 1 Rengel-Tuban who experienced mathematical anxiety in learning. In order to investigate the occurrence of students’ mathematical anxiety, students were given mathematics anxiety test. The products of this research were lesson plan, worksheets, and an achievement test. The results showed that (1) the develop cooperative learning tools with TGT types have met the good quality criteria as they were valid, practical, and effective, and (2) the learning process applying TGT was effective to overcome students’ mathematical anxiety in learning. The effectiveness was known from the ability of the teacher to organize the learning process which was considered good; students’ activities in learning were effective; the students’ responses are positive; and the classical mastery of the learning reaches by 100%. Moreover, the students’ mathematical anxiety problem in learning was reduced
