Giving maximum 5 points per slide helps the student not get overwhelmed with information.
There are a lot of new and innovative mediums as technology and the internet continue to evolve. PP is somewhat of an original but the idea is well founded. Keep it simple; makes it better for the presenter and the receiver.

The 10-20-30 PPT implementation rule.
Using a variety of visuals helps reach all students, keep them engaged and creating a great learning environment!
