Sabrina, The research continues to show strong increases in online course and program enrollments so you are right for the forseeable future those numbers should continue to rise. Let me be the devil's advocate on the statement about math instruction online. What if the course was a synchronous course and everyone had tablets with a stylus. Most synchronous tools have built in whiteboard where the instructor and students can write just like a whiteboard in the classroom. Or the instructor could use an attached document camera and paper to work out problems. Collaboration tools that mimic these traditional classroom interactions do exist. Based on that information do you think that students could do math effectively online? Why/Why not? Herbert Brown III
