Abstract

This study determined the level of conceptual understanding and genetic misconceptions among Grade 12 STEM students and served as the basis for a proposed Genetics Misconception Remediation Worksheet (GMRW). The study employed a quantitative descriptive-comparative research design involving Grade 12 STEM students selected through simple random sampling. Data were gathered using a researcher-made Genetics Conceptual Understanding and Misconception Test (GCUMT) with a Certainty of Response Index (CRI). Findings revealed that students generally understood genetics concepts but demonstrated misconceptions in molecular genetics, DNA replication, protein synthesis, and genetic engineering. Based on the findings, a remediation worksheet was proposed to address identified misconceptions and improve conceptual understanding in genetics
