Purpose of the Study

• To make some preliminary determination on the
  effectiveness of asynchronous streaming of
  classroom-based instruction when compared to the
  traditional classroom setting

Video Was Delivered Directlyto the Students
Desktop

• We did not broadcast to studios or computer labs
  where students would have to gather to
  participate in a site-to-site modeldelivery was
  directly to the students desktop at home or in
  an office

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

12
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

13
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

14
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

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

20
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

21
Future Research

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