Grades, Tutoring and Student Perception: Do Embedded Videos Make a Difference in an Asynchronous Online Course?

Three years of data were examined for an introductory college statistics course comparing results pre and post implementation of videos in support of discussions, assignments, homework, quizzes, and exams. Frequency of external tutoring was significantly reduced (55%) and the number of tutoring hours was reduced by 51% for the course sections that included embedded videos.
