  • Memory Helper is an illustration of a made up dietary supplement. Because the supplement is named Memory Helper, and because a picture of a brain is placed on the label, consumers might believe that the supplement is a memory aid. We add the footnote “tested?” to suggest that consumers should take a closer look.

    In-class peer grading of daily quizzes increases feedback opportunities

    Learning Objectives
    Each of these objectives are illustrated with a succinct slide presentation or other supplemental material available ahead of class time through the course administration system. Learners found it particularly helpful to have video clips that remind them of mathematical manipulations available (in the above example objective c). Students understand that foundational objectives tend to be the focus of the quiz (objectives a-d) and that others will be given more time to work on together in class (objectives e-g), but I don't specify this exactly to reduce temptation that 'gamers' take a shortcut that would impact their group work negatively later on. However, the assignment for a focused graded group activity is posted as well, so it is clear what we are working towards; if desired individuals could prepare ahead of the class.
