Last fall, researchers at Bellwether Education Partners began research on how standard authorizing practices could discourage or disadvantage charter schools with nontraditional models, such as dual language immersion, Montessori, and competency-based education models. Throughout the course of their research, the authors spoke to dozens of school…

Expert skill in music performance involves an apparent paradox. On stage, expert musicians are required accurately to retrieve information that has been encoded over hours of practice. Yet they must also remain open to the demands of the ever-changing situational contingencies with which they are faced during performance. To further explore this…

In an effort to understand the process of skill acquisition and decline, researchers have largely neglected a critical aspect of this development--maximizing time at the highest levels of achievement. This study examined length of career for professional athletes in basketball, football, ice hockey, and baseball and considers whether career length…

There have been several rather counterintuitive phenomena observed in different fields of research that compared the performance of experts and novices. For example, studies of medical expertise demonstrated that less experienced medical students may in some situations outperform seasoned medical practitioners on recall of specific cases. Studies…

Background: Worked examples are very effective for novice learners. They typically present a written-out ideal (didactical) solution for learners to study. Aims: This study used worked examples of patient history taking in physiotherapy that presented a "non"-didactical solution (i.e., based on actual performance). The effects of model expertise…

A performance theory for conflict detection in air traffic control is presented that specifies how controllers adapt decisions to compensate for environmental constraints. This theory is then used as a framework for a model that can fit controller intervention decisions. The performance theory proposes that controllers apply safety margins to…

The purpose of this study was to identify and examine the methods that professional dancers use to engage fully into their work as artists. Participants (N=15) were professional dancers from five European nationalities, (7 females; 8 males), currently performing for three major Scotland-based dance companies, including two professional free-lance…
