Contextual Biology Learning On Hemodialysis And Nutrition To Enhance Students’ Scientific Literacy And Nutritional Awareness: A Systematic Review

Abstract

 Scientific literacy and nutritional awareness are essential 21st-century competencies that should be reinforced in biology education. This study aims to examine the effectiveness of contextual biology learning using the topics of hemodialysis and nutrition to enhance students’ scientific literacy and nutritional awareness through a systematic literature review. Relevant scientific articles from 2018 to 2024 were selected from databases such as Google Scholar and Publish or Perish. The findings indicate that contextual approaches, including the REACT model, Problem-Based Learning (PBL), and Socio-Scientific Issues (SSI), are effective in improving conceptual understanding, critical thinking skills, and awareness of health and nutrition issues. Hemodialysis and nutrition as instructional themes successfully connect biological material to real-world problems, thereby increasing learning relevance and promoting scientific application in daily life. Thus, integrating contextual topics in biology education is a strategic approach to fostering scientific literacy and nutritional awareness at the secondary education level.
