THE EFFECT OF ETHNOSCIENCE INTEGRATED PHENOMENON BASED LEARNING WITH PBL ON STUDENTS' SCIENTIFIC LITERACY ON TEMPERATURE, HEAT AND EXPANSION MATERIAL AT SMP NEGERI 27 MEDAN TP 2023/2024

This research aims to determine the influence of the ethnoscience-integrated phenomenon based learning with PBL on students' scientific literacy abilities in the material heat temperature and expansion at SMP Negeri 27 Medan T/P 2024/2025. The research used a quasi-experimental design with a Pretest and Posttest Control Group Design. The sample consists of two classes, namely class VII-2 (Experimental Class) with ethnoscience-integrated phenomenon based learning with PBL and class VII-3 (Control Class) using the PBL learning model. Sampling was carried out using the Random Sampling technique. Data collection was carried out using tests, observations, interviews and documentation. Data were analyzed by testing the hypothesis using the Independent Sample t-test and effect size test. The hypothesis of this research was tested using the t test and it was obtained that tcount= 4.449 was greater than ttable=1,670 with =0.05 with a significance level of 95%, so tcount>ttable then Ha was accepted and Ho was rejected. Meanwhile, the calculation effect test obtained 1.13 in the Very high category. Based on the hypothesis test, it can be concluded that the ethnoscience-integrated phenomenon based learning with PBL on heat temperature and expansion material has an effect on the scientific literacy abilities of class VII students at SMP Negeri 27 Medan.
