This study aims to find out whether there are differences in mathematics learning outcomes for students who are taught using the Team Assisted Individualization learning model with students who are taught using conventional learning models. The place and time used in this study was at Satu Atap Setu Middle School in Bekasi in the Even Semester of the 2013/2014 Academic Year. From these schools, three classes were selected to be used as samples in the study. Namely class VIII-A consisting of 30 students as an instrument trial class, VIII-B consisting of 30 students as a comparison class and class VIII-C consisting of 30 students as an experimental class. In the study, researchers used experimental research methods by comparing one experimental group (using the Team Assisted Individualization learning model) with a comparison group (using the Conventional learning model). In measuring learning outcomes, researchers used a written instrument (post test) which validity was first calculated. The post test consists of 25 multiple choice questions. To calculate the reliability of the instrument, researchers need to calculate the value of the correlation coefficient using the KR-20 formula, namely rcount = 0.881. Meanwhile, to calculate normality from the research data obtained, researchers used the Lilifors test with a significance level of 5%. From the results of the calculation analysis, it was obtained that the value of Lcount = 0.0976 for classes using the Team Assisted Individualization learning model and the value of Lcount = 0.1333 for classes taught by the Conventional learning model. The value of Ltable = 0.1610 is obtained from looking at the Normality Test table in accordance with the applicable provisions. Because the calculated value obtained by the two classes is smaller than the table value, the two classes are declared to be normally distributed. The homogeneity test of this study used Fisher's test and obtained the value of Fcount = 1.018 with Ftable = 1.85. Because Fcount < Ftable: 1.018 < 1.85 , the two groups are homogeneous. The hypothesis test in this study used the t-test, based on the calculation results, the value of tcount = 3.452 was obtained, while ttable for n1 = 30 and n2 = 30 was 2.01, so tcount > ttable: 3.452 > 2.01. This shows that there are significant differences in learning outcomes using the Team Assisted Individualization learning model and the Conventional Model.
