Pare down the problem and present the issues students should consider when trying to solve the problem. It is important to assess students as they work through their problem-based learning project. There are a variety of ways that you can do this. Most problem-based learning units are completed in groups, but it is important to assess students both individually and as a group. Before students begin the unit, tell them how they are going to be assessed, and share any rubrics that you have developed.
Students realize that their situation is one that real professionals encounter in society.
Assess students in the same way that the problem-based instruction was structured. In other words, if you ask students to create a model building, then you should not give them a multiple choice test. Rather, you might evaluate them as an architect or a building inspector. Provide students with reasonable guidelines and expectations. Most real-world problems can be solved in many different ways.
