Comparison Of The Impact Of Pre And Post Lecture Quizzes On Student Learning In An Engineering Economics Course

In the past, the author has occasionally used the WebCT course delivery system to administer quizzes to encourage students to read the text before lecture. These quizzes have focused on the highlights of the material and were intended to encourage the student to come to class prepared for the lecture. During the Spring 2004 offering of Engineering Economics at the University of San Diego this practice was modified to determine whether these pre-lecture quizzes affected student learning. One half of the class completed the quizzes before hearing the lecture on the material. The other half of the class completed the quizzes after hearing the lecture. Students also completed brief surveys assessing how well they understood each lecture immediately after the lecture. In this paper, the relationship between the timing of the quizzes and student perceptions of their understanding of the lectures is explored. The effects of quiz timing and lecture comprehension on homework and exam grades are also examined. The results of this work show that the students who read the text before the lecture tended to understand the lecture better than students who did not complete the reading assignments, and that they also performed better on exams and in the course.
