The effect of intermittent feedback and intermittent contingent access to play on printing of kindergarten children.

Intermittent grading of papers and the combination of intermittent grading with contingent access to play were evaluated as methods for increasing the accuracy of kindergarten children's printing responses. For a group of target letters, intermittent grading alone failed to produce an increase in accuracy, but when grading was paired with access to play, accuracy increased for every child. These results were then replicated with another letter.
