Web-Supported Chemistry Education: Design of an Online Tutorial for Learning Molecular Symmetry

  • Ali Korkmaz
  • William S. Harwood


This paper describes our use of the ADDIE protocol to design and develop an interactive tutorial for students learning molecular symmetry operations and point groups. The tutorial provides a 3-D environment where students can examine molecules, structures, and symmetry elements. Most such tutorials are connected to courses or instructors in ways that make them difficult for others to use. Our goal was to create a freely available tutorial that would be independent of course, textbook, or instructor but would scaffold student learning of these abstract concepts. A usability study was also conducted in order to assist the designers in creating or improving key features of the tutorial and to determine whether the tutorial would be viewed as valuable to students. We found that students appreciated the features, especially mouse-overs and applets that afforded the opportunity to freely rotate accurate images of molecules.
