IMPLEMENTATION OF COOPERATIVE LEARNING MODEL OF STRUCTURAL APPROACH NUMBERED HEADS TOGETHER TO IMPROVE STUDENTS’ MATHEMATICS ACHIEVEMENT IN CLASS VIII.6 SMP NEGERI 16 PEKANBARU

Abstract

This research was conducted because there are still many student learning outcomes that score below the value minimum mastery criteria (KBM) with a percentage of 10,34 % who achieve the minimum mastery criteria on the associating build flat side space of learning mathematics of class student VIII.6 SMP Negeri 16 Pekanbaru. This research aims to improve the learning process and mathematics learning outcomes by Cooperative learning structured approach Numbered Heads Together. The Classroom Action Research with two cycle, conducted in class VIII.6 SMP Negeri 16 Pekanbaru in the second semester of the 2018/2019 academic year. Research subject as many as 29 students. The research instrument consists of learning devices and instrument data collectors. The learning device consists of Syllabus, Lesson Plan and Worksheet.
