Riipen's model of project-based experiential learning can work for any class size, and we'll work with instructors to design the right format. We've worked with class sizes of up to 1500 students.
In large classes, it likely will not be feasible for every student team to work with their own company. We will usually recommend that for large classes, many teams work on a single project. To keep things manageable for the company, communication goes through the instructor, or a lead contact selected from the students. The company will often introduce the project to students through an initial web or in-person presentation, so that everyone starts off on the same footing.
Students can select the top projects from their peers to pass on to the company representative, so that a limited number of teams can still receive direct feedback from the company.
