Improving college students' evaluation of text learning using idea-unit standards.

When recalling key definitions from class materials, college students are often overconfident in the quality of their responses. Even with commission errors, they often judge that their response is entirely or partially correct. To further understand this overconfidence, we investigated whether idea-unit judgements would reduce overconfidence (Experiments 1 and 2) and whether students inflated their scores because they believed that they knew answers but just responded incorrectly (Experiment 2). College students studied key-term definitions and later attempted to recall each definition when given the key term (e.g., What is the availability heuristic?). All students judged the quality of their recall, but some were given a full-definition standard to use, whereas other students first judged whether their response included each of the individual ideas within the corresponding correct answer. In Experiment 1, making these idea-unit judgements reduced overconfidence for commission errors. In Experiment 2, some students were given the correct definitions and graded other students' responses, and some students generated idea units themselves before judging their responses. Students were overconfident even when they graded other students' responses, and, as important, self-generated idea units for each definition also reduced overconfidence in commission errors. Thus, overconfidence appears to result from difficulties in evaluating the quality of recall responses, and such overconfidence can be reduced by using idea-unit judgements.
