I agree, generally; however, I believe the lownhanging fruit is in assistive tools for teachers.

The commenter above made a good point about the value of removing barriers to learning as a primary asset of a good teacher. People tend to focus on content knowledge/curriculum as the mark of good teaching, but removing barriers is the real, difficult work. Tools that assist the instructor in understanding their students’, their students’ knowledge, and their learning behaviors would be valuable. Don’t focus on content delivery. Focus on making in-class assessment more frequent and trustable. Focus on tools that assist an instructor understand thirty students as they might understand five.
