Using video to convey knowledge as well as illicit information is what I’m doing since 13 years. However, I always felt frustrated about not being able to give the student a working self-assessment tool to find out if the content was understood and the message was received. I finally figured a way to address my need to have a self assessment included in our instructional videos, at least in those that are aimed on conveying procedural skills.
DREXLO is a novel non-linear video-based media format for the teaching and assessment of procedural medical skills. DREXLO has three modes, which allow for the active engagement of the learner and which allow for the assessment of the learner’s behaviors and skills in the educational process. Modes include:
OBSERVE: Playing back video clips in a predetermined sequence
NAME: Playing back random video clips out of the sequence and asking the learners to give their observations descriptive titles
DO: Asking the learners to actively build the sequence themselves, which works as follows: A descriptive title for the clip is entered in the system. The input is then analyzed and the user is provided with options. The selection of an option plays the corresponding video sequence – and the spot of this specific clip within the sequence is displayed.
See "http://webcampus.drexelmed.edu/demo/DREXLO/" for functional DREXLO-prototypes.
We have applied for a Stemmler grant to conduct research on the efficacy of DREXLO for the learning of procedural skills. They will let us know by April 7 2007 if they will fund our research project.
This presentation will show a novel video-based media type that puts the learners into an active position, and allowing them to easily self-assess if the message provided by the video is understood. Everybody who teaches procedural skills or methods could benefit from this presentation.
