摘要

本研究旨在确定在课堂上应用合作学习的数学问题解决能力、编号头像和学生团队成绩划分的差异。从理解、计划、解决和评价四个方面解决数学问题的能力。样本随机从12个班级到2个班级中选取。这两个班将被给予不同的待遇。用于数据分析的数据分为测试前数据和测试后数据。在对这些数据进行检验后，说明了正态性和同质性。假设检验结果具有显著性水平，dk = n1 + n2 - 2 = 74, t表= 1.9953得到t count = 4.433，即-1.9953 1.9953。因此h0被拒绝，这意味着棉兰Pahlawan国立中学七班代数教材中采用NHT型合作模式教学的学生与采用STAD型合作模式教学的学生在数学解题能力上存在差异。

PERBEDAAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA YANG DIAJAR DENGAN MODEL KOOPERATIF TIPE NUMBERED HEAD TOGETHER (NHT) DAN STUDENT TEAMS ACHIEVEMENT DIVISION (STAD)

This study aims to determine differences in the ability to solve mathematical problems, in the class applied cooperative learning numbered head together and the student team achievement division. The ability to solve mathematical problems in terms of four aspects including understanding, planning, solving, and evaluating. The sample was chosen randomly from 12 classes to 2 classes. The two classes will be given different treatments. The data used for data analysis are pre-test data and post-test data. After testing these data, normality and homogeneity are stated. The results of hypothesis testing with a significance level, dk = n1 + n2 - 2 = 74, and t table = 1.9953 obtained t count = 4.433 so that -1.9953 1.9953. Thus H 0 is rejected, which means that there are differences in the mathematical problem-solving abilities of students taught by using the NHT type cooperative model and by using the STAD type cooperative model in algebra material in class VII of the Pahlawan Nasional Middle School of Medan.
