Scheduling math practice: Students' underappreciation of spacing and interleaving.

Many randomized controlled experiments in the classroom have found that mathematics learning is improved dramatically when practice problems of one kind are distributed across multiple assignments (spaced) and mixed with other kinds of problems (interleaved). In two studies, we investigated students' knowledge of spacing and interleaving. In Study 1, 193 undergraduates designed learning schedules for a hypothetical math class.

Do Gender Differences in Perceived Prototypical Computer Scientists and Engineers Contribute to Gender Gaps in Computer Science and Engineering?

Women are vastly underrepresented in the fields of computer science and engineering (CS&E). We examined whether women might view the intellectual characteristics of prototypical individuals in CS&E in more stereotype-consistent ways than men might and, consequently, show less interest in CS&E. We asked 269 U.

The contribution of judgment scale to the unskilled-and-unaware phenomenon: how evaluating others can exaggerate over- (and under-) confidence.

The unskilled-and-unaware phenomenon occurs when low performers tend to overestimate their performance on a task, whereas high performers judge their performance more accurately (and sometimes underestimate it). In previous research, this phenomenon has been observed for a variety of cognitive tasks and judgment scales. However, the role of judgment scale in producing the unskilled-and-unaware phenomenon has not been systematically investigated.

General knowledge monitoring as a predictor of in-class exam performance.

Background: Current theories of self-regulated learning predict a positive link between student monitoring accuracy and performance: students who more accurately monitor their knowledge of a particular set of materials are expected to more effectively regulate their subsequent study of those materials, which in turn should lead to higher test performance.

Aims: The present study further explored the link between monitoring accuracy and performance by investigating whether monitoring of one set of materials would predict performance on a different set of materials.

Sample: The participants were college students (N= 379) enrolled in an educational psychology course.

Study strategies of college students: are self-testing and scheduling related to achievement?

Previous studies, such as those by Kornell and Bjork (Psychonomic Bulletin & Review, 14:219-224, 2007) and Karpicke, Butler, and Roediger (Memory, 17:471-479, 2009), have surveyed college students' use of various study strategies, including self-testing and rereading. These studies have documented that some students do use self-testing (but largely for monitoring memory) and rereading, but the researchers did not assess whether individual differences in strategy use were related to student achievement. Thus, we surveyed 324 undergraduates about their study habits as well as their college grade point average (GPA).

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).

Using standards to improve middle school students' accuracy at evaluating the quality of their recall.

When recalling key term definitions from class materials, students may recall entirely incorrect definitions, yet will often claim that these commission errors are entirely correct; that is, they are overconfident in the quality of their recall responses. We investigated whether this overconfidence could be reduced by providing various standards to middle school students as they evaluated their recall responses. Students studied key term definitions, attempted to recall each one, and then were asked to score the quality of their recall.
