For the casual learner there are a few thousand short, interesting, and educational video clips from which to learn. For teachers and students, they can log in, connect with one another and track progress. The instructor can develop a playlist, and monitor student progress, use it for remediation, or enrichment. Awards are given to motivate, and they are astronomy related! Whether you're a student, teacher, or someone wanting to learn new things, try this out for yourself. If your child is struggling, set up a coaching relationship and watch their progress, because their success is also your responsibility. It's free, easy to use, and contains a wealth of great information.
