  1. Incorporating Mastering for Lab Assignments • University of Alabama Usage in Chemistry Laboratories • University of Alabama Chemistry Lab Statistics • How it works • Benefits • Disadvantages Presented by Erica Livingston, University of Alabama

  2. Incorporating Mastering for Lab Assignments Advantages Disadvantages Students are not completing assignments in advance Students come to lab unprepared for the days experiment Unprepared students create an unsafe laboratory environment Excessive answers sharing among students Traditional Prelaboratory Assignments • Paper prelabs are easy to administer • Paper prelabs are easy to maintain

  3. Incorporating Mastering for Lab Assignments • University of Alabama • Beta tested system Spring 2008 with questions corresponding to the Vincent /Livingston manual 1st and 2nd Edition, accompanying the 1st and 2nd Edition Tro book • Fall 2010 • 54 sections using online pre-lab assignments through Mastering Chemistry • Approximately 1,200 students

  4. Incorporating Mastering for Lab Assignments Advantages Disadvantages Requires use of online access which may be limited for some students. Requires time to set up courses, grade and manage system issues. • Fulfills desire to equip students with a working knowledge of procedures, calculations, theory and safety concerns within each laboratory. • Requires students to look over laboratory material previous to lab time resulting in a better understanding of the laboratory material. • Allows them to look over the material at their own pace and use other resources to complete the assignments. • Allows for a more extensive laboratory experience. • Most portions are self graded resulting in less grading time required for Graduate Teaching Assistants. • Lowers the rate of sharing answers among students in sections.
