TeacherTube is a great tool because:

• It has an almost endless array of videos.
• It's simple to navigate.
• It's easy to use.

It will improve the effectiveness of learning by:

• Teaching students visually.
• Helping students to understand be reinforcing ideas.

I can use this in the classroom by:

• Showing students different videos in class.
• Having the students find a video which is relevant to whatever we're discussing in class.
