Abstract

Free, open, online, help forums connect students with volunteer helpers who provide assistance with specific problems from coursework. One of the most popular existing mathematics help forums, Cramster, is an advocate of Cognitive Load Theory (CLT), and promotes the provision of worked solutions. The purpose of this project was to ascertain the quality of the worked solutions that students are receiving, by analyzing 128 threads from the Algebra thru Pre-Calculus site archives from two perspectives. First, a rubric based on research-based design principles of worked examples was used to distinguish poor from wellstructured solutions. Second, student ratings of solutions they received were examined and compared with the research-based ratings. The results show that Cramster is providing students with responses that contain steps, and sometimes goals, as opposed to final answers only. However, there is also much misinformation in the responses, and students do not show much discernment in their ratings.
