The critical and creative thinking skills (CCTs) of junior high school students remain at a low level. Following this phenomenon, this research was conducted to explore the potential of the Problem Based-Learning model (PBL) to enhance students' CCTs, using a single class with a single group pretest-posttest design involving the ninth-grade students from State Junior High School in Malang, Indonesia. The sample was selected using the purposive sampling technique. Data was gathered through evaluation instruments in the form of pretest and posttest results. In addition to the aforementioned instruments, teaching modules and student worksheets were employed in the data collection process. The data analysis was performed using a number of tests, including the Shapiro-Wilk data normality test, Wilcoxon test, and N-Gain test. In particular, these tests were carried out to evaluate changes in scores. The research findings indicated that the implementation of PBL was effective and significantly successful in improving students' thinking skills, especially their CCTs. This is evidenced by the Wilcoxon test results, which resulted a significance value of less than 0.05, as well as a high N-Gain increase for critical thinking (0.7001) and a medium category for creative thinking (0.5826). Therefore, these findings can serve as recommendations concerning the role of PBL in improving students' two thinking skills (CCTs).

The objective of this study was to ascertain the impact of critical thinking skills on the learning outcomes of junior high school students, with the Self- Organized Learning Environment (SOLE) learning model serving as the experimental framework. The research methodology employed was quasi- experimental, with a research design of nonequivalent control group design. In this study, the experimental class was Grade 8 A Class, while the control class was Grade 8 C class. The SOLE learning model demonstrated a statistically significant effect on critical thinking skills and learning outcomes, as evidenced by the t-test results with a value of 0.05 < 0.000. The N-gain score for the SOLE learning model revealed that 51.5% of the learning outcomes were less effective, while 56.8% of the critical thinking skills were moderately effective. In contrast, the control class in the Discovery Learning learning model achieved 32.3% in learning outcomes and 38.2% in critical thinking skills, both of which were ineffective. The results of the research indicate that critical thinking skills and junior high school science learning outcomes are significantly influenced by the SOLE learning model.

This study investigates science learning outcomes on the topic Matter and Its Changes among seventh-grade students at MTs, with a focus on gender differences. Using a descriptive survey method, the entire population of 77 students (two male classes and two female classes) was involved. Data were collected through post-tests, questionnaires, observations, and interviews, and analyzed quantitatively using the Mann-Whitney U test. The results show that female students had significantly higher average learning outcomes (64.04) compared to male students (45.50). Further analysis revealed that female students performed better at cognitive levels C3, C4, and C5, as well as across all subtopics. Qualitative findings from teacher interviews suggest that this difference is consistent and may be attributed to female students’ ambition and logical reasoning, as observed in class. However, questionnaire data indicate that male students report higher self-confidence. The study concludes that gender differences significantly influence science learning outcomes, with implications for instructional strategies and gender-responsive teaching practice

Critical thinking and learning motivation are essential competencies for 21st-century students; however, these skills remain relatively low in science education due to teacher-centered instruction and the limited use of engaging media. To address this issue, innovative approaches that integrate effective learning models with appealing learning resources are required. This study investigates the effect of incorporating a Problem-Based Learning (PBL) science magazine on junior high school students’ learning motivation and critical thinking skills in ecology and biodiversity. A quantitative research design was applied using a pretest–posttest control group design, involving two groups of students including an experimental class that used a PBL-based science magazine and a control class that employed a discovery learning worksheet. The results of the independent sample t-test revealed statistically significant differences between the two groups. Furthermore, the N-Gain test demonstrated high effectiveness, with an N-Gain score of 0.71 for learning motivation and 0.70 for critical thinking skills. These findings suggest that the integration of PBL-based science magazines has a substantial positive impact on students’ learning motivation and critical thinking, highlighting the potential of combining innovative models and media to strengthen science learning outcomes.

Science education in Indonesia faces challenges in improving students’ science literacy skills, which are often still low. The objectives of this study are to assess the impact of using the “ELGASE” learning media on improving students' science literacy skills and to identify differences in science literacy skills before and after the implementation of the “ELGASE” media. The method in this study was pre-experimental involving 22 students of class VIII. Data were obtained through observation, testing, and documentation collection methods, then analyzed using the normality test and the N-Gain test to evaluate changes in scores. The results showed that the use of “ELGASE” media provided a significant increase in students’ science literacy skills. This improvement is measured through a nonparametric test (Wilcoxon), which indicates the difference or comparison of pretest and posttest scores on each indicator. The study results indicate that the use of “ELGASE” media significantly improved students’ science literacy skills, with the N-Gain score for the first indicator being 0.80 (80%) and for the third indicator 0.92 (92%), classified as “Effective” and “Highly Effective”, respectively. Additionally, the second indicator showed an increase of 0.58 (58%), falling into the “Moderate” category, which demonstrates a medium level of effectiveness in enhancing students’ understanding of the taught material. The conclusion of this research is that the “ELGASE” media is proven effective in improving students’ science literacy skills and can be recommended for use in science learning.
