To increase student learning
Oral assessments have been shown to improve student conceptual understanding, student grades, and increase the number of students passing the course at the University of Colorado (see Assessment, below). Prior research has also shown that both testing and feedback are crucial to improving learning (Karpicke and Roediger, 2008; Nicole & Macfarlane-Dick, 2006; Gibbs & Simpson, 2004).
To increase student engagement
Oral assessments are by nature student-centered, active-engagement activities. Additionally, oral assessments have improved course attendance. During the assessment students learn to help each other by asking questions and other active techniques rather than working problems for one another.
To emphasize sensemaking and reasoning
Oral assessments emphasize the reasoning behind answers, providing individualized feedback on student thinking. A major goal of the orals is to help students articulate their thinking, make sense of ideas and make mathematical connections.
To learn more about student thinking
By using oral assessments, instructors, Teaching Assistants and Learning Assistants learn more about how students are thinking about the material and see firsthand the power of active learning.
