1. Backward shaping is a teaching procedure whereby the last step in a learning sequence is taught first and mastered. Then the next to last step is taught, mastered, and then built onto the final step. The process is systematically added on back to the initial stage of the sequence. The desired sequence is taught in reverse.
2. This does not teach someone to perform the movement backwards. The procedure starts with the end point action and merely develops or shapes the movement from that stage. Everything is focused on building into the final point. Gradually the form of the entire action takes place.
3. The probability of learning interference from previously mastered skill is eliminated.
