2.2.2. Challenges: Expensive, generally mounted (not portable)
2.2.3. Applications to learning: i. Use the computer to “write” on displayed digital images without actually altering the original ii. Modeling, showing sample work iii. Optional microscope attachments for science iv. Point lens at students for live projection of skits, etc. v. Display text for shared reading
