The Influence of the Two Stay Two Stray (TSTS) Model on the Learning Achievement of the Material Properties of Light in Elementary School 2 Sukamulya

Abstract

The study aims to determine the influence of the Two Stay Two Stray (TSTS) learning model on the learning science at fourth grade in SDN 2 Sukamulya. The problem in this study is that there are several obstracles in learning the material of science. Those are less attractive in learning the material the characteristics of radiance because it tends to use conventional learning, lack of use media-aided so students are less active, lack of implementing the learning model used in the learning process, low cognitive in learning achievement of students. In overcoming the problems that by using two stay two stray learning model (TSTS). In this learning model, students can be active in science learning and learn the material by using media-aids to make them understood easily. The research method used the quasi experimental with the design method using non-equivalent group design. The sampling technique uses total sampling, for the distribution of the control class and the experimental class selected randomly. There where each class is 20 students in class IV A, and also IV B were 20 students. Data collection techniques used unstructured interviews, test and documention, data analysis techniques used the normality test with the Shapiro-wilk formula, homogeneity test with one-way anova formula, and statistical hypotheses using the t-test formula. In the experimental class IV A SDN 2 Sukamulya as class experimental showed mean of pretest was 68,00 and the mean posttest value was 81,25. Moreover, in class IV B SDN 2 Sukamulya as control class. It showed the mean of pretest was 56,75 and the mean of posttest was 66,25. The results of the hypothesis test showed that the significance value is 0,000 < 0,05. It can be concluded that there is an influence of the TSTS learning model in the learning achievement of learning the material the radiances's characteriatics at class IV Sukamulya SDN 2.
