Premo, Joshua; Cavagnetto, Andy; Honke, Garrett; Kurtz, Kenneth J. – Journal of Research in Science Teaching, 2019
The idea that characteristics acquired by an organism during its lifetime can be inherited by offspring and result in evolution is a substantial impediment to student understanding of evolution. In the current study, we performed a preliminary examination of how acquiring physical changes in a question prompt may differentially cue intuitive and…
