Integrating MapReduce concepts into core CS curricula

There is little debate regarding the necessity to include parallel and distributed (PDC) concepts in the undergraduate computer science (CS) curriculum. However there may be debate as to the best way to do so; the extent of coverage necessary; and the best approach to accomplishing one's specific goals. At Wake Forest, our approach has been to develop PDC modules for use in existing courses rather than adding PDC courses to our core requirements. We have previously developed and employed modules built on a message passing paradigm. In the current work we report on efforts to develop MapReduce-based instructional modules for introductory and intermediate level courses. With this module approach we can introduce students to important PDC concepts earlier in their studies. This early introduction to MapReduce can be very beneficial to CS majors but also to students pursuing programs in business, engineering, and the social sciences.
