At the beginning of the school year, Mr. Webber is concerned that Frances rarely does her independent seatwork. He begins praising Frances for each seatwork assignment she completes, and by January she is completing her assignments regularly. To make sure that the behavior continues in the years to come, what would behaviorists tell Mr. Webber to do now?

Praise her for only some of her completed assignments.                                                                                  

Explanation:

Operant conditioning: In psychology, the term "operant conditioning" was proposed by a psychologist named B. F. Skinner as a way of explaining the study that has been done by Ivan Pavlov on laboratory dogs.

Operant conditioning is also referred to as instrumental conditioning and is described as one of the different types of "associative learning processes" according to which the "strength" of a specific behavior is being modified or altered via punishment or reinforcement.

In the question above, Mr Webber would praise her for only a few completed assignments.
