"A central concept in the No Child Left Behind Act of 200 1(PL 107-110) is that federal funds should support programs and strategies that are backed by scientifically based research," said U.S. Secretary of Education Rod Paige. This information presents a summary of the research that demonstrates the effectiveness of using video to supplement the educational curriculum. The e-Mod Interactive Digital Video System meets this requirement.
Federal Definition
SCIENTIFICALLY BASED RESEARCH - The term scientifically based research:
(A) means research that involves the application of rigorous, systematic, and objective procedures to obtain reliable and valid knowledge relevant to education activities and programs; and
(B) includes research that:
(i) employs systematic, empirical methods that draw on observation or experiment;
(ii) involves rigorous data analyses that are adequate to test the stated hypotheses and justify the general conclusions drawn;
(iii) relies on measurements or observational methods that provide reliable and valid data across evaluators and observers, across multiple measurements and observations, and across studies by the same or different investigators;
(iv) is evaluated using experimental or quasi-experimental designs in which individuals, entities, programs, or activities are assigned to different conditions and with appropriate controls to evaluate the effects of the condition of interest, with a preference for random-assignment experiments, or other designs to the extent that those designs contain within-condition or across-condition controls;
(v) ensures that experimental studies are presented in sufficient detail and clarity to allow for replication or, at a minimum, offer the opportunity to build systematically on their findings; and
(vi) has been accepted by a peer-reviewed journal or approved by a panel of independent experts through a comparably rigorous, objective, and scientific review.
Research Synopsis
The most recent research on the effectiveness of utilizing videos to enhance classroom instruction was conducted by Cometrika, Inc. during 2002. This study assessed the impact of using video clips, delivered over the Internet. Third and eighth-grade students in Virginia were shown selected video clips related to state learning standards in science and social studies. Participating teachers received training in use of the video technology, prior to beginning instruction. Control groups covered similar content, but without exposure to the video clips.
All students were pre- and post-tested on a project-developed measure of the Virginia Standards of Learning. Differences between experimental group pre- and post-tests scores were compared with control group pre- and post-test differences. Experimental groups for 3rd grade science, 3rd grade social studies, and 8th grade social studies showed a significantly greater increase in scores on the post-tests over pre-tests than did the control groups. No significant difference existed between the 8th grade science group and the control group, a result possibly due to a lag time between the teacher training and implementation for that experimental condition. Overall, the students exposed to the video clips exceeded the control group post-test scores by 12.6%, an effect size that was about .66 of a standard deviation unit.
The results of this study demonstrate the effectiveness of using video in the classroom to enhance learning.
