Abstract

This study aims to determine the increase in the ability to understand the concept of grade V elementary students through the TGT learning model. Quasi experimental research method and Nonequivalent Control Design Group design. Participants in this study were the fourth grade students of SD who were 40 students. Sampling in this study uses Nonprobality and saturated sampling techniques. Data analysis in the study used the ability to understand students' mathematical concepts, and documentation. From the results of the understanding of mathematical concepts ability of elementary school students in Purwakarta experienced a significant increase after obtaining learning with the TGT model. This is evidenced by the results of the calculation of the N-gain test data obtained P-Value (Sig-tailed) of 0.000 <0.05. The acquisition of the results of the average value of the experimental class Posttest is 60.25 and the results of the control class average Posttest score are 23.75. This means that an increased understanding of the experimental class mathematical concepts is higher than the control class. Thus it can be concluded that the TGT learning model is recommended as an alternative learning model in improving understanding of the mathematical concepts of elementary students in Purwakarta

Abstract

Scaffolding is a learning strategy that is used in learning by providing assistance to taste to students based on the difficulties experienced by students. The purpose of this research is to know the influence of scaffolding strategies against the ability of mathematical understanding of grade III SD in Purwakarta. This research uses a quantitative approach with quasi experimental research methods and research designs The Nonequivalent Control Group Design with techniques of sampling Non Probability Sampling the sampling type is saturated. The object of this research is the whole grade 3 SD 2017/2018 school year with a total of 48 students (Male = 23, female = 25). Data collection techniques in the study using this type of test in the form of sheets of matter and types of the non test in the form of observation and documentation. Data analysis in this study uses the construction and validity testing of the validity of the content. The results showed there is the influence of the use of scaffolding strategies against the mathematical understanding of the capabilities of the students. This calculation results obtained from test-t with P-Value calculation results (Sig 2-tailed) for 0.000 which means less than 0.05 significant level. The earnings results of the pretest average score at 29.92 while IE experiment class results average value of experimental class posttest was 73.92. Then for obtaining the value of an average pretest classes control i.e. 30.96 while the average value of posttestnya was 55.17. The use of scaffolding strategies can be used by subsequent researchers to conduct research in the subject matter, having regard to the appropriations used and skills of teachers in the conditioning classes, to obtain maximum results.
