Adding value to educational content by applying MRA filtering

To support the creation of quality online teaching material by nontechnical domain experts, the availability of intelligent specialized user interfaces is of an essence. We introduce a filtering algorithm allowing to constructively apply the multiple representation approach (MRA) best practice guidelines for media object combinations, so that educational content units are brought in compliance without any effort on the part of the user. Content enrichment based on MRA filtering is illustrated by implementing a proof-of-concept prototype.
