By combining traditional course content written by educators at ChildU and the latest multi-media techniques in Macromedia Flash, students access lessons such as math, language arts, science, and social studies on the web at any time.

Each lesson allows students to work at their own pace with the help of Oncall's custom animated characters who speak to the students and walk them through each learning activity, much like a teacher in a traditional classroom.  The games, quizzes and other interactive activities promote lesson retention, and teachers supplement the student's experiences in the classroom.
