THE EFFORTS TO OVERCOME STUDENTS' MISCONCEPTIONS ON SCIENCE LEARNING SUB-CONCEPT BIOTECHNOLOGY AT MTSPN 4 MEDAN

Abstract

The purpose of this study was to determine the efforts to overcome students' misconceptions in
learning science, especially in biotechnology material. The method used in this research is
descriptive method with qualitative and quantitative approaches. The research population was
all students of class IX MTsPN 4 Medan in the academic year 2021/2022, totaling 20 people.
Determination of data sources/subjects of this research is based on cluster sampling technique
because the number of informants is relatively small and random, less than 30 people. Previous
research literature is also used as additional material. Data collection techniques using test and
interview techniques. Data collection in this study used a test in the form of multiple choice
accompanied by CRI (Certainty of Response Index). The data obtained from the results of the
study were then analyzed using descriptive statistical techniques, to distinguish students who
understand concepts, misconceptions and do not understand concepts. The results obtained that
there were misconceptions about science lessons, especially biotechnology material in class IX
students of MTsPN 4 Medan in the 2021 academic year with a level of 15.46% in the subconcepts
of
basic
principles
of
biotechnology,
9.81%
in
conventional
biotechnology,
17.85%
in

modern

biotechnology. , and 18.44% in the sub-material of the application of biotechnology.
Based on the results of the study, the causes of student misconceptions can occur because of
the individual himself, the debriefing that students receive and the handbook. Efforts that can
be made to reduce the occurrence of misconceptions are the provision of material according to
the concept, detailed explanations, and discussions.
