	The Future City Competition is an example of problem-based learning with computer simulation, in STEM (Science, Technology, Engineering, and Mathematics) education. The program asks 6th, 7th and 8th grade students from around the nation to team with engineer-volunteer mentors to create – first on computer and then in three-dimensional models – their visions of the city of tomorrow. A program of the DiscoverE organization, it has been operating since 1992 and currently serves over 40,000 students.
