The million-dollar question: blackboard or document camera? Or at least this was the question in a Math 53 class earlier this semester.

The class, according to a bSpace poll, was equally divided. Here we discuss some of the pros and cons of each:

Document Camera: (for those of you who don’t know what this is, it’s basically the 21st century equivalent of an overhead projector)

Document Camera

Pros:

• No messy erasing on the chalkboard
• Can upload notes online
• Can project things like pages from a book without any extra work

Cons:

• Can’t reuse same space
  • Which means using a lot of paper

Chalkboard:

Chalkboard

Pros:

• No additional technology that can break
• Face it: we’ve been using chalkboards forever. Something must be right.

Cons:

• Messy erasing
• Chalk breaking
• Dust
• Face it: we’ve been using chalkboards forever. They’re getting old.

Of course, there are always whiteboards…but has anyone actually seen a whiteboard in any classroom at Cal?
