Abstract

This study was conducted because some students are still less able in learning multiplication or have not memorized multiplication from 1 to 10 and students who still think that multiplication operations are difficult to memorize, so that their multiplication calculation ability is still quite low. This study aims to determine the effectiveness of the jarimatika method with the Problem Based Learning (PBL) model on the multiplication calculation ability of grade 3 students of SD Negeri Pangarangan V. This study uses a quantitative descriptive research type with a descriptive model and a pre-experimental design approach. The sample in this study used 30 grade 3 students. Data collection techniques used in this study were observation, interviews, documentation and tests. Hypothesis testing requires data collection, in this study the researcher used a test (pretest-posttest). The implementation of the pretest and posttest can be seen from the average. The average pretest score obtained by students was 60.33 and the posttest score obtained by students was 80.00. Furthermore, the prerequisite test, namely the normality test, the researcher used the Shapiro Wilk technique. Based on the results of the normality test, the P-value at Sig. (2-tailed) in the pretest is 0.062 <0.05 and the P-value at Sig. (2-tailed) in the posttest is 0.065 <0.05. Next is the hypothesis test using the t-test (paired sample t-test), the results of the t-test calculation (paired sample t-test) using the help of SPSS 26 computer software show the P-value results at Sig. (2-tailed) of 0.000 which means <0.05 means H0 is rejected and Ha is accepted. Thus, the results of the hypothesis test state that the jarimatika method with the Problem Based Learning (PBL) model is effective for the multiplication calculation ability of grade 3 students at SDN Pangarangan V.

Abstract

This research was conducted due to the low learning outcomes in the science subject at SDN Lalangon I. This research aims to determine the effectiveness of the contextual teaching and learning (CTL) model on the science learning outcomes of class V on the material of light and its properties. This research uses a quantitative approach of the experimental type. The research model used is true experimental with a pretest-posttest control group design. The sample in this research used a simple random sampling technique, namely 42 students of SDN Lalangon I which were divided into class VA as many as 21 people as the control class and class VB as many as 21 people as the experimental class. The data collection techniques used are observation, tests, and documentation to determine student learning outcomes in the learning process. The data analysis used includes prerequisite tests and hypothesis tests. Based on the data analysis that has been done, it can be seen that the average score of the experimental class is 80,47 and the control class is 66,19. From these results it can be seen that the average of the experimental class is higher than the control class. In addition, the hypothesis test through the t-test also showed a significant value (2-tailed) of 0,000 which means less than 0,05 (0,000 <0,05). Through the manual, the t-count value was obtained at 15,565 and the t-table was 2,016 which means the t-count value> t-table (15,565> 2,016), so Ha is accepted and Ho is rejected. In the n-gain score test, the mean n-gain percent value obtained a result of 67,56% which indicates an effective category. It can be concluded that the contextual teaching and learning (CTL) model is effective for the science learning outcomes of class V on the material of light and its properties.
