Oklahoma students know less about evolution after Biology I than they did before taking it

A study published in the latest edition of Evolution: Education and Outreach demonstrated “the average student…completed the Biology I course with increased confidence in their biological evolution knowledge yet with a greater number of biological evolution misconceptions and, therefore, less competency in the subject.”

The study, conducted by Tony Yates and Edmund Marek, tested biology teachers and students in 32 Oklahoma public high schools via a survey the pair called “the Biological Evolution Literacy Survey.” The survey was administered to the teachers first, to get a benchmark of their grasp of evolutionary theory. The survey was then administered twice to the students — once before they took the required Biology I course, and once after they had completed it.
