This study empirically tests the feasibility and effectiveness of video lectures as a form of video instruction that enables a comprehensive teaching strategy used throughout a traditional classroom course.It examines student use patterns and the videos' effects on student learning, using qualitative and nonparametric statistical analyses of survey responses and student grades.Groups of student course grades are compared with and without video lectures available.Enabling a Comprehensive Teaching Strategy IIP -72 of learning style preferences to which video lectures appeal.A statistically significant 68.5% of students using the videos said they helped understand course information and prepare for midterm exams.A statistically significant 72.2% said the videos helped do homework and prepare for weekly exams.Moreover, a statistically significant 63% of students said they provide tutoring help.These use patterns indicate broad acceptance of the computer-based instruction in video lectures, delivered by the course instructor, as a supplementary resource in a traditional course.They indicate that video lectures appeal to many students for a variety of purposes, and are effective for learning.Regarding course grades, survey responses indicate that the video lectures helped 20.4% of students pass the course.Observing grade data, 24.2% of students without the videos failed the course.This rate dropped to 6.8% for the sample group with the videos available -a substantial improvement.Evaluating video lectures as a study resource for comprehensive final exams, they provide an entire semester's lectures delivered by the instructor.Final exam data show that the availability of video lectures improves final exam grades for all grade ranges.
