My Take
BrainPop is a great for introducing a concept or reinforcing what you have taught. Students navigate the videos and can repeat them if necessary. The quizzes are a great way to assess content and possible reteaching. Cute cartoon-type characters keep all student levels engaged.
How I Use It
I use it with almost all subject levels. It has a variety of resources to go along with most of the videos as well as lesson plans. Students can also access it from home if the school purchases it so it can be a homework-type tool or to reinforce what was learned at school.
