Successful Problem Solving In Genetics Varies Based On Question Content

Problem solving is a critical skill in many disciplines but is often a challenge for students to learn. To examine the processes both students and experts undertake to solve construct-ed-response problems in genetics, we collected the written step-by-step procedures indi-viduals used to solve problems in four different content areas. We developed a set of codes to describe each cognitive and metacognitive process and then used these codes to de-scribe more than 1800 student and 149 expert answers. We found that students used some processes differently depending on the content of the question, but reasoning was consis-tently predictive of successful problem solving across all content areas. We also confirmed previous findings that the metacognitive processes of planning and checking were more common in expert answers than student answers. We provide suggestions for instructors on how to highlight key procedures based on each specific genetics content area that can help students learn the skill of problem solving.
