"When was the last time you saw groups of students excited about math?" I would make the recommendation if there are other large school districts who are interesting in coming on board and providing a 21st century environment for 21st century students, they should do this..."

The Effects of Modern Math Computer Games on Learner's Math Achievement and Math Course Motivation in a Public High School Setting:
"The results also support findings from two meta-analysis, including: (a) Vogel et al. (2006) who concluded that interactive simulations and games were more effective than traditional classroom instruction on learners' cognitive gains based on a review of 32 empirical studies, and (b) Dempsey et al. (1994) who concluded that students who played math video games and attended the traditional classroom instruction achieved higher mathematics score than students who only attended traditional classrooms based on 94 empirical studies."
The use of computer and videogames for learning: A review of the literature
Link from link a NC State wiki with inforation about DimensionM:
"DimensionM is a video game that immerses students into a virtual world with the intention of teaching them mathematics concepts using familiar game constructs. This video game targets middle and high school students and covers pre-Algebra and Algebra objectives through a series of missions. In each mission the students enter a reality-based environment where they are introduced to new math concepts. Throughout the missions students challenge themselves to understand and master the math concepts to improve their performance in the game. Students cannot move from one phase to another until they have completed the math problems or tasks with 100% accuracy."
