- Freelance K-5 writer/editor of interactive material (This one and the next are Quarasan virtual listings. They have a couple of freelance positions based in Chicago as well)
- On-site Freelance ELL/ESL Editor, K-12 (Says on-site, but listed as virtual)
- Middle-School Math Teacher/Curriculum Designer at Airy Labs (I can't tell if telecommute is an option. It might be)
Okay, so I didn't find much, but I did come across a new name through this post: Curriculum/Writer Instructional Designer (Raleigh - Downtown). The company is GCFLearnFree.org. This position is full-time, but they look like they might be a decent prospect for the future.
Here's another I hadn't come across before: Anaxos: An Educational Media Company. Their contact info says
