Video Was Delivered Directlyto the Student’s Desktop
  • We did not broadcast to studios or computer labs where students would have to gather to participate in a site-to-site model—delivery was directly to the student’s desktop at home or in an office

study design
Study Design
  • This study used a quasi-experimental design with students in the face-to-face classroom section as the control group and students in the online asynchronous streaming video section of the course as the treatment group
  • An independent t-test was used to compare the means of the control and treatment group results

Sawa and Flower, “Asynchronous Streaming Video”

hypothesis
Hypothesis
  • It was hypothesized that the results of this study would show no significant difference between the student grades of the control (classroom students) and treatment group (students viewing asynchronous video), or, that the grades of the participants in the treatment group would be significantly higher than those of the control group

methodology 1
Methodology (1)
  • Using the streaming video system we designed and built, we taught “Computer Skills for Administrators” during the Spring of 2005
  • There were 8 students in the classroom and 10 students viewing asynchronous streaming video of classroom activities
  • Course is an elective with no pre-requisites offered in the Professional Studies Division

Sawa and Flower, “Asynchronous Streaming Video”

methodology 2
Methodology (2)
  • Both groups had the same class presentations, readings, and assignments, wrote the same reports, took the same tests, and worked on similar projects
  • Both groups could watch the archived class video files that were posted the next day

grade score components
Grade Score Components
  • Testing throughout the semester: 45%
  • Final exam: 20%
  • Class participation/Quality circle participation: 10%
  • Group presentation/Group presentation contribution: 15%
  • Critical review of Visions: How Science Will Revolutionize the 21st Century by Michio Kaku: 10%

results
Results
  • Statistical analysis of the student grades showed no significant difference in four out of the five categories examined
  • The online students scoring significantly higher in the fifth category (Exam 3)
  • Low cost narrow bandwidth asynchronous streaming of classroom-based instruction appears to be as effective as the traditional classroom environment in this instance

Sawa and Flower, “Asynchronous Streaming Video”

methodological data problems
Methodological/Data Problems
  • Groups are not random
    • Groups are self-selected by enrollment in a classroom or online section
    • Neighbor Island students have no choice; they must enroll in an online section
  • Population may not be representative of all college students
  • Not “blind”; instructor knows who is in each group

Sawa and Flower, “Asynchronous Streaming Video”

future research
Future Research
  • More rigorous study and analysis of classroom-based asynchronous streaming video needs to be performed to confirm these preliminary findings
