Instructors are charged with the responsibility of providing students with resources that will support their learning. The rising use of technology in the classroom brings about new resources that can potentially help or even hinder students’ understanding of content. Sections of introductory chemistry utilized online homework as part of their courses. Students performance (n=297) was measured using a pretest and posttest of the 2003 California Diagnostic Exam. Academic gains were measured by evaluating the change in performance between the pretest and posttest. Academic gains of students who completed a minimum amount of online assignments were compared to those demonstrated by the students who completed less than the minimum amount of the online assignments. The differences in performance and implications for the use of online homework in introductory chemistry course will be discussed.
