Cristal rushes through her spelling assignments and her seatwork. she likes to finish first and read, but she makes careless mistakes and turns in incomplete work. her teacher has tried several strategies that have not worked with cristal. now she plans to use applied behavior analysis. she tells cristal that the goal is for her to complete the seatwork with fewer than three errors and no incompletions. she tells cristal she will give her a token each time she meets the goal. if she achieves five tokens in a week, she will choose a reward from the surprise basket. now what does the teacher need to do?

The teacher is using a token economy.

Explanation:

A token economy is a type of behavioral strategy that involves the use of certain reinforcements with the aim of modifying an individual's behavior - either to remove undesired behaviors or incite appropiate ones.

By complying with the therapist's instructions, the individual will receive tokens that can be traded for rewards.

In this case, the teacher wants Cristal to turn in complete assignments. This is achieved by offering Cristal a reward inside the basket in exchange of the proposed task.
