Teachers often use rubrics to communicate their expectations for student work and allow for evaluation (self-evaluation, peer-evaluation, or teacher evaluation) of that work. A typical rubric consists of a table in which the various dimensions of quality are listed one per row, and the levels of quality are the columns. In each cell is an explanation of what is expected at that level in that dimension, and possibly examples, means of evaluation, and/or points assigned for attaining that quality level. Rubrics allow for a richer evaluation than simply right/wrong (and thus for richer, more engaging assignments), help communication, and help make fundamentally subjective quality decisions clearer and more objective. Software for supporting the creation and use of rubrics would be appropriate for OLPC.
