In recent years, most students in my project-based AP Government classes have indicated, in both class discussions and anonymously on surveys, that they prefer project-based learning to a more traditional classroom experience. They find PBL more fun and believe that it leads to deeper learning. However, two types of students often resist this model. Students of the first type generally do not enjoy school at all, and are looking for the path of least resistance. Because a PBL classroom is student-centered and calls on students to produce, less-motivated students will find it more difficult to "hide" and be left alone. The second type of student has already been very successful in traditional classrooms and is deterred by the challenges of this new model. These students are often highly motivated by grades, and worry that the project cycles will detract from direct content delivery.
