Content Creation / Development for Educational purposes

I'm just curious, if I was looking to put out educational content (potentially for classroom use), what would be the best away of approaching this?  I'm not strong on 3d modelling, but I do have application programming experience.  I was wondering if there was anything already made or in pre-production with the ability to pre-render content (e.g. record a 3d math lesson)? Anything people are using already to make educational materials?  I feel like math and physics could really be well served with some great visuals and would work well in 3d, especially in terms of keeping people from getting bored.

Any advice would be appreciated.
