Abstract

Scientific literacy plays a role as scientific knowledge and skills to be able to identify questions, acquire new knowledge, explain scientific phenomena, and draw conclusions based on facts, understand the characteristics of science, awareness of how science and technology shape the natural, intellectual, and cultural environment, as well as the willingness to be involved and concerned with science-related issues. Science plays an important role in the development of Science and Technology, therefore scientific literacy needs to be introduced from an early age and taught in primary, secondary and higher education so that knowledge, understanding, and science skills are embedded in children, both in the form of critical thinking skills, hard skills as well as soft skills. Scientific literacy is required in various branches of science. Learning Plant Physiology which is one part of the biological sciences, the inclusion of scientific literacy is a necessity, so that the Learning Outcomes of Courses (CPMK) and Graduate Learning Outcomes (CPL) are maximized. Improving scientific literacy in plant physiology learning can be applied through various innovative learning models including: (1) Project Based Learning (PjBL) learning model, (2) Problem Based Learning (PBL) learning model, (3) Experimental learning model to explore the surrounding environment ( EJAS), (4) Discovery Learning model, (5) Service Learning model, (6) Inquiry learning model. All of these learning models are constructivist, so they can improve critical thinking skills, problem solving skills, higher order thinking skills and the ability to interact socially humanities

Abstract

Indonesia is a tropical country that has a variety of soil types, types of climate, both macro and micro climates and other environmental factors, causing Indonesia to have a diversity of biological resources arranged in a high diversity of ecosystems, both natural and artificial ecosystems. Agriculture is an artificial ecosystem that functions to support the lives of farmers socio-economically. An agricultural ecosystem that is less stable will result in a decline in agricultural production and a decline in the health of people who consume agricultural products as the main food ingredient. In agricultural cultivation, controlling pests and plant diseases is absolutely necessary to increase agricultural yields. Vegetable pesticides are pesticides whose active ingredients come from plants or plants and other organic materials which are effective in controlling pest attacks and plant diseases. The ingredients for these vegetable pesticides are sourced from various types of existing plants. The active compounds in these botanical pesticides are biodegradable so they are safe for the health of the environment and consumers.

Abstract

Biology is the study of living things, both existing and extinct. Biology learning becomes more contextual when conducted within a school environment. In relation to the immersive learning approach, environment-based learning can increase awareness, meaning, and enjoyment. These three learning principles are implemented through thought, heart, feeling, and exercise. These four efforts are an integral part of education that shapes the whole person (personality or character). The Teaching Assistance Program in the Biology Education study program is crucial for implementing school-based learning within high school (SMA) units. Every essential material in each phase is taught by maximizing the school environment. This article is based on the concept of learning activities carried out for each essential material in phases E and F of high school (SMA) units.

Abstract

The STEM (Science, Technology, Engineering, and Mathematics) approach significantly enhances literacy and numeracy learning by integrating multiple disciplines to solve real-world problems. This integration fosters critical thinking, problem-solving skills, and deeper contextual understanding of scientific and mathematical concepts. This study aims to develop a STEM-based assessment framework for literacy and numeracy at the senior high school level, guided by indicators from the Programme for International Student Assessment (PISA). The research focuses on analyzing the characteristics of STEM-oriented literacy, science, and numeracy items, and constructing an assessment model tailored for schools targeted for PISA-level improvement. A mixed-methods approach was employed, comprising three stages: (1) exploration and analysis of STEM-based PISA item characteristics, (2) development and pilot testing of STEM-based assessment instruments, and (3) design of a comprehensive STEM-based literacy and numeracy assessment concept for broader implementation. The study involved instrument development, initial trials in selected partner schools, and item analysis to evaluate validity and reliability. Findings indicate that the developed instruments have strong potential to identify students’ critical thinking and problem-solving skills in alignment with the PISA framework Pendekatan STEM (Science, Technology, Engineering, and Mathematics) memberikan kontribusi signifikan dalam pembelajaran literasi dan numerasi dengan mengintegrasikan berbagai disiplin ilmu untuk menyelesaikan masalah kontekstual dunia nyata. Integrasi ini mendorong pengembangan kemampuan berpikir kritis, pemecahan masalah, serta pemahaman yang lebih mendalam terhadap konsep-konsep sains dan matematika. Penelitian ini bertujuan untuk mengembangkan konsep asesmen literasi dan numerasi berbasis STEM di tingkat Sekolah Menengah Atas dengan merujuk pada indikator Programme for International Student Assessment (PISA).
