Student’s Misconception Profile of First Semester 10 th Grade on Biology

Abstract

This research aims to describe the student's misconception of first semester on biology subject at 10 th grade senior high school. There are seven concepts on first semester such as scope of biology, biodiversity, classification of living things, virus, bacteria, protist, and fungi. The participants consisted ten students from public and private schools. The data collection instrument contains 35 biology test items. The diagnostics instrument were valid and reliable tested on Lawshe's CVR and Aiken's V. Initially determined of Lawshe's CVR that only one item lacked interrater proportion agreement (CVR =-0,2) and Aiken's V analysis of validity shows only three items had low coefficient of content validity. The findings confirm the results, majority of the students in science class have misconceptions which were caused by incorrect understanding on biology concepts. Highly misconception happens in the protist concept and followed by biodiversity concept.
