Riipen's model of project-based experiential learning can work for any class size, and we will work with instructors to design the right format. We have 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 usually recommend that for large classes, many teams should 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 video-conference.
Students can select the top projects amongst their peers to submit to the company, so that a limited number of teams can still receive direct feedback from the employer.
