Realizing the ongoing need to develop pedagogy in public speaking, these researchers investigated the learning achieved by asking students to repeat one of their speech assignments. They assessed the value of this practice from the students' viewpoint as well as the statistical change in performance outcomes. Across the eight competencies evaluated, students' average scores increased significantly on the repeated speech. Students who scored in the lower quartile on the first speech benefited most from the second opportunity. The researchers conclude that allowing students to repeat a speech appears to have pedagogical and practical merit.
