Problem-based learning is sophisticated because it offers students the opportunities to learn by playing the role of working professionals in a simulated organization. Also, sophistication is achieved by integrating modern technology such as digital engineering, 3D printing, graphic design, and website creating. In the Biodiversity PBL, students play the role of engineers in an engineering firm by offering digitally engineered proposals (one proposal per engineer) for an educational oasis off of a nature trail in a local park, for the purpose of promoting environmental advocacy. The problem was presented to students that without forming environmental advocates in the community, then biodiversity will drastically decrease. Environmental advocates can do things like asking city council representatives, and other elected officials, to vote for conservation of habitats.
