PENGARUH PENGGUNAAN MODEL CTL BERBASIS BUDAYA SASAK TERHADAP LITERASI MATEMATIKA SISWA KELAS III SDN 20 CAKRANEGARA TAHUN AJARAN 2024

Abstract

This research aims to encourage the influence of the Sasak culture-based Contextual Teaching and Learning (CTL) learning model on the mathematical literacy abilities of class III students at SDN 20 Cakranegara. This research uses a quantitative approach with a quasi-experimental non-equivalent control group design. The population consisted of 56 students who were divided into two classes: class III A as the experimental class and class III B as the control class. The sampling technique used was a saturated sample, where the entire population was taken as the research sample. Data was collected through observation and written tests. The research instruments include written tests and observations, which have been tested for validity and reliability. The research results show that the application of the CTL model based on Sasak culture is effective in increasing students’ mathematical literacy. This is shown by the increase in the average posttest score in the experimental class (89.94) compared to the control class (78.57), as well as the results of the N-Gain test which shows a significant increase of 83% in the experimental class. Apart from that, the independent t-test results show a sig value. 2-tailed is 0.000, which is less than 0.05 (sig. 2-tailed < 0.05), so Ha is accepted and Ho is rejected. This shows that there is a significant influence of the Sasak culture-based CTL learning model on the mathematical literacy abilities of class III students at SDN 20 Cakranegara.
