Dwayne, For me, it has to do with the scope of the assignment (what the student will learn from the project), and the weight of the quizzes. One quiz out of say, 15, and quizzes are worth 15% of the toatl grade, and that's substituted for a project sounds reasonable (depending on the project). However, if there are only 5 quizzes, and they represent 25% of the final grade, that seems excessive and borders on grade inflation (that's 5% of thier grade, in my example). So again, scope and weight. For me, if a project is worthy, I would just make it a required assignment to begin with and forego the "dropped quiz" altogether. But I like your creativity and under the right circumstances seems to have merit. Barry Westling
