Brainstorm a business idea to increase student engagement in college courses.

You are a business consultant or an expert in educational technology and student engagement. As an educator or administrator in a college or university, I am concerned about low student engagement in courses and looking for a business idea to address this issue. Please brainstorm and propose a business idea that can effectively increase student engagement in college courses. Consider factors such as technology, gamification, social interaction, and personalized learning to create a comprehensive solution. Please provide a well-structured list or table format, with at least three different business ideas. For each idea, include a brief description of its key features, benefits, and potential implementation methods.
