Piagetian Formal Operational Tasks: A Crossover Study of Learning Effect and Reliability

Lawson, Anton E.; And Others

Science Education, 58, 2, 267-276, Apr-Jun 74

The general purposes of this study were to analyze responses on five Piagetian formal operational tasks in a test-retest situation to determine the extent to which taking a pretest effected scores on posttests and to determine task and examiner reliabilities. Significant test score gains on Piagetian tasks appeared to result from test-retest effects. (PEB)
