Design a psychological experiment to answer the following question:
Which of the following is better at improving the academic performance of second grade students . . .
(a) using rewards and positive reinforcements.
(b) using negative consequences (punishments).
IN ADDITION, your experimental design should contain a deliberate flaw . . . you must either include a mistake in your experimental design that would make the results unreliable or you must deliberately include a design element that would make your experiment unethical (morally wrong).
You may be called on to share your design to see if your classmates are able to identify the error that you have deliberately included in your experiment.
