Cellular and molecular perceptions of students, skills students and biology education student teachers of genetic phenomena: a cross-sectional study

Genetic concepts are divided into three main levels, macroscopic, microscopic, and sub-microscopic. In order to study the understanding of the students of the twelfth year of the experimental field, biology graduate skills students, and biology student teachers semester 7 in the connection between the ideas and concepts of these three levels, Various questions were asked by the audience who wanted to use molecular concepts and processes to bridge the gap between these levels in understanding genetics. The results of this cross-sectional study showed that students and some student teachers can’t understand the microscopic and sub-microscopic levels of genetics. Skills students had a better cellular and molecular understanding of genetic events than the other two groups. The difficulty for students in understanding the connection of concepts is that the concepts and genetic processes belong to different levels of the organization and these people have not been able to analyze the relationship between the levels. Based on our findings, it is necessary to consider improvements in both teaching methods and curriculum content.
