Early reading skills are fundamental competencies that must be mastered by elementary school students, as they serve as the foundation for future academic success. However, conventional teacher-centered instruction often fails to maximize students’ active engagement in learning. This study aims to analyze the effectiveness of the Project Based Learning model assisted by mind mapping media in improving the early reading skills of second-grade elementary students. This research employed a quantitative approach with an experimental design. The participants were second-grade students who received instruction through the Project Based Learning model assisted by mind mapping media. Data were collected using reading skill tests administered before and after the treatment. The data were analyzed to identify differences in students’ reading abilities following the implementation of the learning model. The findings indicate that the implementation of Project Based Learning assisted by mind mapping media has a positive effect on students’ early reading skills. The model promotes active student participation, enhances critical and creative thinking skills, and facilitates comprehension through structured visual representation of concepts. Furthermore, the learning environment becomes more interactive and meaningful, increasing students’ motivation to engage in reading activities. Therefore, the Project Based Learning model assisted by mind mapping media is recommended as an alternative instructional strategy to improve early reading skills in elementary schools.

Education is a crucial foundation for shaping a generation with strong character, faith, intelligence, and responsibility as mandated by Law Number 20 of 2003. In the 21st century, one of the most essential competencies to be developed is critical thinking, which can be effectively nurtured through Project Based Learning (PjBL). This approach actively engages students in planning, inquiry, problem-solving, and reflection within project-based tasks, making learning more meaningful. This study examines the effect of PjBL on the critical thinking skills of fifth-grade students in Natural and Social Sciences (IPAS) at SD Islam Istiqomah, Ungaran Barat, Semarang Regency. Employing a quantitative method with a quasi-experimental Nonequivalent Control Group Design, the study involved 76 students divided into experimental and control groups. Data were collected using a validated and reliable essay test on critical thinking skills. Results showed that the experimental group achieved a higher mean posttest score (84.16) than the control group (74.74). The point-biserial correlation was rpb = 0.676, and the t-test result (tcount 7.891 > ttable 1.993, p < 0.05) confirmed a significant difference. These findings demonstrate that PjBL substantially improves students’ critical thinking and emphasize its continued implementation to foster contextual and meaningful IPAS learning.

This research was conducted on fourth-grade students of SD Negeri 01 Karang with the aim of analyzing the effect of the implementation of the Javanese culture-based Project Based Learning (PjBL) model on students' communication skills in the 2025/2026 academic year. The research subjects were 25 students, consisting of 12 male students and 13 female students. This type of research is quantitative with a One Group Pre-Test Post-Test Design. The research procedure began with the administration of a pre-research questionnaire to determine the level of instrument validity, and the results of the validity test showed that there were 10 questionnaire items that met the valid criteria for use in data collection. Data analysis was carried out through a normality test using the One-Sample Shapiro-Wilk formula and a hypothesis test using the Paired Sample T-Test formula. The results of the analysis showed a significance value <0.000 with a probability <0.05, so it can be concluded that the research hypothesis is proven, namely there is a significant effect of the implementation of the Javanese culture-based PjBL model on improving the communication skills of fourth-grade students. These findings confirm that project-based learning linked to local cultural contexts not only improves communication skills but also helps students better understand and appreciate their local cultural values. Thus, cultural integration in the PjBL model is an effective strategy for improving the quality of learning, both academically and strengthening students' cultural identities.
