comment Evolution education is a complex landscape Researchers in various contexts have long struggled with an apparent disconnect between an individual’s level of understanding of biological evolution and their acceptance of it as an explanation for the history and diversity of life. Here, we discuss the main factors associated with acceptance of evolution and chart a path forward for evolution education research. Ryan D. P. Dunk, M. Elizabeth Barnes, Michael J.

In the context Son what is known about the current acceptance: understanding the nature of of evolution education, it is clear (and research on evolution acceptance and where science (the means, aims, processes, and confirmed by research) that certain religious further work is needed.

Earlier uses appropriate strategies to reduce who understands little about the evidence research in the field searched for a conflicts and obstacles induced by such for evolution might accept it as a matter of relationship between evolution acceptance experiences18–20. This approach should lead scientific consensus, while another person and understanding but found contradictory to an increase in both understanding and might reject evolution on religious or other results1,10–13. However, more recent acceptance of evolution—indeed, in one non-scientific grounds despite having a studies employing multifactorial models study, identification with evolution acceptors good understanding of the concept. have shown an independent significant was found to be the only factor significantly As a result, ever since evolution became association between evolution knowledge related to change in evolution acceptance21. a dominant paradigm in biology, evolution and acceptance when controlling for other Along with teaching in a culturally educators have faced a distinctive challenge: variables6–8,14, although the strength of this competent manner, the demonstrated how to cope with religious and other non- association varies between studies.

Here, While an instructional approach focused acceptance, learning and understanding we use our collective knowledge and almost exclusively on evolution knowledge more about the scientific enterprise could experience to summarize what is known may increase acceptance of evolution for help students become better-informed about acceptance of evolution, describe students without religious barriers15, such citizens and more aware of the processes a path for further exploration, and offer an approach may isolate and discourage common to all scientific disciplines.
