Lack of student participation during discussions causes students to become inactive when learning, and difficulty in answering teacher questions because the information the teacher conveys is not understood by students. This results in student scores still below the KKM in Global warming is one of them. The minimum completeness criteria set at SMPN 2 Lembah Gumanti is 65. The purpose of the study was to determine the effect of the application of the guided inquiry model with video media on the biology learning outcomes of seventh-grade students of SMPN 2 Lembah Gumanti, Solok Regency. The type of research is an experiment with a research design Randomized Control Group Posttest Only Design. The use of t-test is used in the affective domain as a data analysis technique and the t-test was used in the cognitive and psychomotor domains for data analysis techniques. 1 the experimental class has an average score of 62.38 with a predicate of C (Enough) while the control class has an average value of 53.22 with a predicate of D (Less). Hypothesis test 0.05 obtained t-count 2.90 > t-table 1.67, meaning that H1 is accepted. The guided inquiry learning model accompanied by video media can improve the biology learning outcomes of class VII students of SMPN 2 Lembah Gumanti, Solok Regency.

This study aims to describe and determine the differences in students' physics process skills through the LKS based on Natural Exploration (JAS) on temperature and heat at SMAN 2 XIII Koto Kampar. The research design used in this study was an intact-group comparison design. The data collection technique in this study was giving tests to the experimental and control classes, after learning through LKS based on Exploring the Surroundings. The average absorption power of the experimental class is 80% in the good category, while the control class is 74% in the good category. Based on students' absorption, it can be said that learning in the experimental and control classes is effective. Classical student learning completeness in the experimental class is 84% and in the control class is 62.5% otherwise incomplete. The classical completeness of the process skill indicator in the experimental class is 100% and in the control class is 75%. In classical completeness, the indicator of process skills in the experimental class is declared complete and the control class is declared incomplete. After the t-test was conducted, it was found that there was a significant difference in physics process skills through LKS based on Exploring the Surroundings by using ordinary LKS.

Giving students the knowledge and skills they need to support sustainable development is one way that sustainability literacy is being promoted. To enhance the material on sustainability literacy, this article maps perspectives on sustainability literacy and the relationship between the Education for Sustainable Development (ESD) idea and chemistry education. The study's objectives are to: (1) map out the body of research on sustainability literacy; and (2) examine how the ESD idea relates to chemistry education to promote sustainability literacy. According to Kitchenham, the approach is Review. 31 international journals published between 2012 and 2023 were the sources of the papers used; they were retrieved from the Google Scholar database and Scopus-indexed. The study's findings demonstrate the widespread applicability of sustainability literacy across a range of scientific domains and application foci. Many well-researched ESD implementation approaches in chemistry education might serve as a guide when creating ESD in the classroom. An overview of the content of sustainability literacy that is pertinent to chemistry education as well as how it may be applied to different learning domains is given in this paper. It also offers perspectives for scientists, chemical instructors, and ESD developers.

The abstract nature of the topics is easily understood while learning chemistry through guided inquiry. This article employs the A Review (SLR) technique to review eleven papers released between 2018 and 2023 that deal with teaching chemistry using various guided inquiry models. Three online article databases—ERIC, Scopus, and Google Scholar—were used to retrieve articles methodically. The information in this review will be helpful to educators and researchers who work in chemical education in understanding guided inquiry models, how they impact chemical learning outcomes, and how to apply them to improve students' comprehension of chemistry. The review's conclusions show how various guided inquiry strategies immerse students in a problem, offer them an investigation to work through and provide guidance on how to solve the problem. Guided inquiry models influence chemistry learning outcomes by enhancing metacognition, concept understanding, critical thinking skills, science process skills, learning outcomes, creative thinking abilities, and reducing misconceptions. Many learning models or strategies, including guided inquiry, guided inquiry-based on blended learning, guided inquiry-based on the flipped classroom, guided inquiry model integrated with STEM, and guided inquiry and task hierarchy analysis model in cooperative learning strategy, have also used different chemistry learning models.
