Sustainability awareness has become an increasingly important aspect of global education, especially in the face of environmental challenges. This approach to education with sustainable principles is needed to educate the current generation to meet their needs without risking the next generation, including the issue of food waste. The purpose of this study is to describe the profile of sustainability awareness in high school students related to the issue of food waste. This research used a qualitative descriptive method. The instrument used was a questionnaire developed from three aspects of sustainability awareness: behavior and attitude awareness, emotional awareness, and sustainability practice awareness. The results of filling out the questionnaire were analyzed by determining the mean and percentage and then categorizing the level of sustainability awareness. The results showed that 56% of students have awareness related to the issue of food waste at a moderate level. So, it can be concluded that students have an awareness of the value of sustainability at an emotional level without practicing it in everyday life.

Today's education requires students to manage their learning independently, so that students can set learning goals, set strategies, and even evaluate learning, so that students' understanding of concepts increases. This is related to the learning model used, one of which is guided inquiry. This study aims to determine the influence of guided inquiry on the understanding of the concept of evolution. This study is a quantitative research with a quasi-experimental research design with a non-equivalent pretes-postes control group design The subjects in this study are students of class XII IPA MA Miftahul Ulum Bettet Pamekasan even semester of the 2024/2025 academic year. Class XII Science B is an experimental class with 32 students, while class XII Science C is a control class with 31 students. Sampling was carried out by random sampling technique. The hypothesis test in this study uses the Unpaired T Test. The results showed that there was no influence of guided inquiry on the understanding of the concept of evolution. However, guided inquiry remains a reference for a learning model that can empower a variety of skills for students. Researchers should then consider the factors of student readiness, especially in student habits and learning styles, time factors, and teachers or researchers should have mastered the learning model to be used.

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.

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).
