Abstract

Abstract: This research is is based on the issue of students' low critical thinking skills, especially in science education. The aim of this study is to determine whether the PjBL learning model based on education for sustainable development can affect students' critical thinking skills. The method used in this study is a quasi-experimental design with a non-equivalent control group type, with a research population of 56 students. The sample consisted of 23 class IV A students (experimental group) and 23 class IV B students (control group). This research sample was selected using a purposive sampling technique. The data collection method used is a test. Based on data analysis, the PjBL model based on education for sustainable development has a significant influence on the critical thinking abilities of fourth grade elementary school students. This is based on the results of the independent t test showing a sig value of 0.000 indicating a sig value <0.05 which can be concluded that  is rejected and  is accepted. Thus, the PjBL model based on education for sustainable development has an effect on students' critical thinking abilities.

Abstract

This study explores the role of real-world contexts in developing students’ mathematical understanding through the Realistic Mathematics Education (RME) approach at Gunung Sekar Elementary School, Sampang. The background of this research lies in the low mathematical comprehension of elementary students, largely due to abstract, teacher-centered instruction. Using a qualitative exploratory case study, data were collected through classroom observations, interviews, and documentation involving 25 sixth-grade students, with six selected for in-depth analysis. The findings revealed that implementing RME by introducing contextual problems such as daily life situations involving division, measurement, and fractions significantly enhanced students’ conceptual understanding, engagement, and confidence in mathematics learning. Students demonstrated improvements in explaining concepts, using multiple representations, and applying mathematical ideas to new contexts. Moreover, the learning process promoted active participation, collaboration, and critical thinking. Teachers transitioned from information providers to facilitators who guided exploration and reflection. The study concludes that the integration of real contexts within RME makes abstract concepts more meaningful and accessible to students, thereby improving both cognitive and affective learning outcomes. These results emphasize the potential of RME as an effective pedagogical strategy to strengthen mathematical literacy and cultivate positive attitudes toward mathematics in Indonesian elementary education.
