Facilitation of the acquisition and retention of sight-word vocabulary through token reinforcement.

The researchers worked with second-grade classes.

They compared two ways to teach sight words.

One group got flash cards plus praise.

The other group got flash cards, praise, and plastic tokens.

Kids could trade tokens later for small prizes.

Both groups had the same number of practice trials.

The token group learned new words faster.

They also remembered more words after a delay.

Praise alone helped, but tokens plus praise worked better.

The gap stayed big even weeks later.

Kirby et al. (1981) copied the idea and added a bingo game.

Kids still earned tokens, and accuracy jumped to over 90%.

The game twist shows the same principle works when practice is fun.

Kupzyk et al. (2011) swapped tokens for a special flash-card drill called Strategic Incremental Rehearsal.

They still beat plain flash cards, proving faster learning can come from either richer reinforcement or smarter drill design.

Clark et al. (1973) did the same thing a year earlier with pennies and praise for reading comprehension.

Together these papers build a chain: add something extra—tokens, games, or better drill—and kids learn more words in less time.

If you run sight-word drills, drop a token board on the desk.

Hand a token for every correct response, let kids trade ten for a sticker.

You will see faster mastery and stronger recall with almost no extra prep.

It is a five-minute setup that pays off for weeks.
