Dynamising conceptual change approach to teach some genetics concepts
Abstract
ABSTRACT
This study investigates the effect of a conceptual change approach over traditional instruction on students’ understanding of DNA, gene and chromosome concepts. 52 10th grade students belonging two different classes participated the study. One of the classes was assigned randomly to the control group, and the other class was assigned randomly to the experimental group. During teaching of the topic of DNA and gene related concepts in the biology curriculum, the conceptual change approach was applied in the experimental group whereas ‘traditional instruction’ was followed in the control group. The data were analyzed using analysis of SPSS 10.0. The results showed that the students in the experimental group performed better when compared to the control group. For the genetic concept achievement test, the posttest average percent of correct responses of the experimental group was % 79.46 and that of the control group was % 59.79 after the treatment. Add to this, it was found that students’ attitudes towards biology lessons made a statistically significant contribution to the variation in students’ understanding of DNA, gene and chromosome related concepts.
