Abstract

This study aims to determine the effect of the Problem-based Learning (PBL) model on improving the scientific literacy of class X students of SMAN 1 Piyungan on environmental pollution material. The research method used is a quasi-experimental design with a non-equivalent control group design. This research was conducted at SMAN 1 Piyungan, even semester of the 2023/2024 academic year. The sample was class E1 as an experiment and class E2 as a control with the same number of students, namely 36 students. Data on students' scientific literacy abilities were obtained using multiple-choice questions. Analysis of the results of students' scientific literacy abilities was calculated using nonparametric statistics, namely the Mann Withney test. The PBL model is effective in improving students' scientific literacy abilities, as can be seen from the results of students' average scores or the results of the Mann Withney test. The average result of scientific literacy abilities in the experimental class was 77.20 with an N-Ggain value of 0.77, indicating that the increase was in the high category, while the average scientific literacy ability in the control class was 41.28 with an N-Ggain value of 0.41, indicating that the increase was in the moderate category. Based on the Mann Whitney test, the students' scientific literacy ability obtained a sig. (2-tailed) <0.05, meaning that there is a significant difference in students' scientific literacy ability between the control class and the experimental class. Based on the data analysis, it can be concluded that students' scientific literacy ability increases with the PBL model on environmental pollution material.

Abstract

The aims of this research is to develop  electronic worksheet differentiated instruction on topic of mangrove ecosystem which improve critical thinking skills. The quality of worksheet determined based on validity, effective, and practical criteria. This research is research and development (R n D and using Plomp model. The subjects are 65 students X grade Senior High School of Abu Bakar Kulon Progo. Data analysis technique uses descriptive analysis and MANOVA test. The results from implementing electronic student worksheet obtained a score of media validity is 81.67, the category is very valid, a score of material validity is 87.86 the category is very valid. The score of practicality worksheet is 97 and 80 from teachers and students, both in the very practical category. Worksheet has significant effectiveness as evidenced by a significance of 0.000 < 0.05, which means that there is a significant difference in critical thinking skills between the control and experimental classes after learning with electronic student worksheet differentiated instruction.

Abstract

Environmental literacy is important in modern education to encourage individuals to become more environmentally aware. This research aims to reveal research trends, research methods, education levels, and countries that conduct environmental literacy research. The technique used is bibliometric analysis. Sixty-eight documents indexed in the Scopus database were analyzed using VOSviewer and Biblioshiny, with publication years ranging from 2019 to 2024. The findings show that the survey method is dominant in environmental literacy research. Environmental literacy measurements in the adult group account for the largest number. Publications about environmental literacy increased significantly in 2020–2021 and 2023–2024. The United States is the leading country in environmental literacy research. Environmental education and environmental literacy are trending topics in this field of research. This shows that there is an increasing research focus on environmental issues in the educational context.
