Based at the University of Delaware, this set of peer-tested and vetted educational resources asks the important question: "How can I get my students to think?" Their educational philosophy places a premium on problem-based learning (PBL), which is an instructional method that asks students to work cooperatively in groups in order to seek solutions to real world problems. First-time visitors can take a look at some sample PBL problems. These sample problems include several group exercises that deal with everything from household wiring to a case study problem in molecular evolution. College instructors will want to definitely visit the "PBL Courses and Syllabi" area, where they can take a look at sample syllabi that draw inspiration from the problem-based learning perspective. Finally, visitors can also browse through the PBL Clearinghouse and look over a list of related educational sites.
