Solve real-world problems.

The PBL Clearinghouse contains problems from a wide variety of disciplines. As the problems and supporting materials are covered by the Creative Commons Attribution-NonCommercial 4.0 International License, you are welcome to borrow and adapt these problems for your classroom. Because these files are open sourced, your students may search and discover the teaching notes and solutions. We encourage you to make changes, adapt the problems to your specific goals and classroom contexts and thereby discourage your students from “borrowing” solutions or otherwise circumventing your instructional goals.

To browse the problems available for use, see the problems table. You can sort on any of the column headings.

If you are interested in contributing to the Clearinghouse, see the Instructions for Authors page.
