Abstract

This study was conducted with the aim of determining the influence of the Everyone is a Teacher Here learning model with the help of ice breaking on students' mathematical numeracy literacy and to find out the average numeracy literacy ability taught with the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking whether it is higher than using conventional learning on comparison material in grade VII SMP Negeri 31 Medan. This type of research is quantitative with quasi experimental design. These results show that H1 has an influence on the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking on students' mathematical numeracy literacy, judging from the t test showing sign results. (2 tailed) of 0.01 < 0.05. The H2 test has no effect of ice breaking on students' mathematical numeracy literacy, judging from the t test shows the results of sign.(2 tailed) of 0.07 > 0.05. As for H3, there is an influence of the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking on students' mathematical numeracy literacy, judging from the f test obtained sign. (tailed) by 0.00 < 0.05. In the N-Gain Score test, Ha is accepted, namely the increase in numeracy literacy taught with the Everyone is a Teacher Here (ETH) learning model with the help of ice breaking higher than students who obtain conventional learning, with an average N-Gain Score in the experimental class of 0.71 > an average N-Gain Score in the control class of 0.41.

Abstract

The purpose of this study was to determine the effect of the Team Assisted Individualization (TAI) type cooperative learning model on students' mathematical problem solving skills in learning mathematics at SMP Negeri 31 Medan. The research method used in this research is quasi-experimental method or pseudo-experiment, and the type of data used is quantitative data. This research uses Pretest-Posttest Control Group research design. The research instrument used is a problem solving ability test, while the data processing technique used in this study is a two-party t test hypothesis test with a significance value of 0.05 and the sample is taken randomly with a total of 62 students. The Lcount value of the experimental class posttest is 0.103 while the Ltabel value is 0.159 with a significance level of 0.05, so it can be concluded that Lcount < Ltabel (0.103 < 0.159) then both classes are normally distributed (HO rejected). The experimental class posttest Fcount value is 0.748 while the Ftabel value is 0.543, with a significance level of 0.05, so it can be concluded that Fcount> Ftabel (0.748> 0.543) then HO is rejected which means the sample comes from a homogeneous data group. Based on the two-party t test statistical test with dk = n1 + n2 - 2 with a significance level of 0.05, it can be concluded that there is an effect of the Team Assisted Individualization (TAI) type cooperative learning model on students' mathematical problem solving skills.
