The Effectiveness of Video Quizzes in a Flipped Class

ABSTRACT

The use of online videos and flipped classrooms is a natural fit for many CS courses, especially in the introductory sequence, and the use of these techniques is growing. However, the benefits of these techniques depend heavily on student preparation before class meetings. This paper presents tests of the effectiveness of basic multiple choice quizzes as gateway checks in a flipped classroom by looking at the impact they have on student grades. Programming aptitude and learning approaches were considered as additional factors. Ignoring aptitude and learning approaches, statistical analysis of the student grades did not support our hypothesis that the gate-check video quizzes would be beneficial. Nor did it support our hypothesis that the benefit of quizzes would be greatest for students who had lower aptitudes entering the class. However, there was some evidence that it might have helped raise the grades of students who have a propensity toward surface learning.
