Youtube has plenty of educational content, from Photoshop tutorials to great speeches from history, just about ever content area can be found on the site. Unfortunately, a ton of inappropriate content can be found too. How can you keep the good yet protect your students from the bad? TeacherTube may be the answer. It's a youtube-like site that has many of the same features yet has some protection built in to keep out the bad.
