1. A method for use in connection with coursework submissions, the method comprising:

  • retrieving from storage, media content to be used in evaluating or organizing the coursework submissions, wherein at least some instances of the retrieved media content constitute, or are derived from, respective ones of the coursework submissions;

    for each instance of the media content, extracting a set of computationally defined features, wherein a set of values for the extracted computationally-defined features together constitute a k-dimensional feature vector that characterizes the corresponding instance of media content;

    initializing elements of an n-dimensional map, n less than k, with current feature vectors; and

    assigning successive instances of the media content to respective elements of the map to which they most closely correspond and iteratively morphing the current feature vectors to produce a self-organized mapping wherein individual instances of the media content are distributed over the map and associated with respective elements thereof.
