Pre and post essay distributions at each institution. Horizontal stacked bars indicate the proportion of essays that fell into each of the broad categories before (pre = prompt 1) and after (post = prompt 2) intervention. “Full Acceptance” refers to any response in which the student expressed an acceptance of evolution with no indication of any rejection of individual components (e.g., human evolution). “Limited Acceptance” refers to any response in which the student acknowledged that evolution occurs but took specific issue with one or more components of the theory (most common components included human origins and speciation events or macroevolution). “Rejection” refers to any response in which the student denied the validity of evolution. Other refers to any response that could not be categorized into any of the first three.
