| Chemistry courses recognize the benefit of homework to reinforce concepts. Online homework programs, such as WebCT and Online Web-Based Learning (OWL), have gained popularity by allowing homework to be assigned while eliminating the grading and recording for the instructor. OWL can be programmed to give students the answers to questions and the solutions to questions, letting students learn from previous mistakes. Using OWL, the effect of feedback, specifically answer solutions, was investigated. A general chemistry class was divided into two groups. During an online quiz the control group received no feedback while the treatment group received feedback on the questions. An in-class quiz was given to the students after the online quiz. A survey was given to currently enrolled students in general chemistry and first semester organic students to determine the attitude toward OWL. The data from the surveys and quizzes was analyzed and the results reported. |
