Abstract

Science learning in elementary schools aims to help students understand scientific concepts through observation and real experiences. This study aims to describe the improvement of fifth-grade elementary school students' conceptual understanding related to the properties of light through the application of the STEM (Science, Technology, Engineering, and Mathematics) learning model. SDN 2 Cilumba conducted the study, employing the pre-experimental method of a one-group pretest-posttest design. The instruments used included a concept understanding test and interviews. The results of data analysis showed a significant increase in students' average scores, from 58.81 (pretest) to 78.53 (posttest). The paired t-test produced a significance value of 0.000 < 0.05, indicating that the STEM model was effective in improving students' conceptual understanding. The results of the interviews revealed that students were enthusiastic about participating in STEM-based learning, even though teachers faced time constraints and students had difficulty restating concepts. Overall, the majority of students were in the good understanding category (60.01%), excellent (26.66%), and sufficient (13.33%). These findings reinforce that the STEM approach can be an alternative to meaningful and intriguing science learning at the elementary school level.

Abstract

The This research is based on the low scientific literacy abilities of elementary school students in science learning. This is based on the results of interviews conducted with class V teachers before the research was conducted. The aim of this research is to determine the increase in students' scientific literacy using the Problem Based Learning learning model. This research was conducted using the Mix Method with The Sequential Explanatory Design. The instrument used is a test instrument for students' scientific literacy abilities. The subjects in this research were class V students in one of the elementary schools in West Bandung Regency, totaling 38 students. The research results show that there is an increase in students' scientific literacy skills using the Problem Based Learning model. This can be seen from the average N-Gain gain of 0.88 and being in the "High" category. Therefore, it can be concluded that the Problem Based Learning model is effective in increasing students' scientific literacy abilities.
