Homework assignments, consequences, and classroom performance in social studies and mathematics.

Teachers gave daily homework in math and social studies. They added a simple rule: hand in work that is at least 80 % correct and you get a small prize or praise the next day.

The study ran in two elementary classrooms. The researchers counted homework turned in, accuracy scores, and how kids answered questions the next day in class.

When the consequence started, homework return jumped from about 50 % to over 90 %. Accuracy also rose from 60 % to above 85 %.

Better homework scores carried into class. Kids gave more right answers during math and social-studies lessons on the days after accurate homework earned a reward.

The result lines up with Clark et al. (1970) and Hall et al. (1970). Those early studies also used token-style rewards in classrooms and saw quick gains in attending and teacher contact.

Fluharty et al. (2024) extends the idea. They let the class pick their own high-prize reinforcer before tying it to a group goal. Both papers show that the prize must matter to the students or the boost fades.

Alba et al. (1972) looks like a contradiction at first. They tried making university lecture attendance depend on finishing prior work, and it failed. The difference is timing: E et al. withheld the grade until the end, while W et al. gave the reward the very next day. Immediate consequences win.

If you run homework programs, do not just collect it—check it and deliver a quick, small reinforcer for accuracy. A sticker, point, or verbal praise the next morning is enough. The payoff is double: more papers come back correct and next-day class answers improve. Start tomorrow by picking one class, set an 80 % correct rule, and hand out a preferred item only to those who meet it.
