Published studies of intervention effects probably report effect sizes that are larger than the true effect size. There are probably many reasons for this, but one can be thought of as a "winner's curse." In this essay, I discuss evidence from two recent studies that highlight how evidence clearinghouses might inadvertently expose…

Consumers are increasingly willing to pay more for sustainably produced goods, yet many find these alternatives too costly and less effective. The fashion industry struggles to balance sustainability and performance, particularly in textiles, where synthetic fibers dominate. Education is key to informed consumer choices, and biomaterials, like…

As we design increasingly complex systems, we run up against fundamental limitations of human imagination. To support practice, it becomes essential to use authentic data and algorithms as design materials to augment designers' intuitions. Recent work has explored some dimensions of using data as a design material, suggesting the contours of a new…

In recent years, McNamara, and associates Hambrick and Oswald, conducted and published studies which purportedly showed deliberate practice exerts less powerful main effects than presented and popularized in the press, public discourse, and professional circles. Their central aim seemed to be one of correcting a particular misperception, as they…

Whereas social support contributes to individual vitality and academic performance, the theoretical process through which social support promotes performance, and for whom it is most beneficial in this respect, remain open questions. We developed a conceptual model in which social support influences academic performance by promoting vitality,…

A central factor in research guided by the Cognitive Load Theory (CLT) is the mental effort people invest in performing a task. Mental effort is commonly assessed by asking people to report their effort throughout performing, learning, or problem-solving tasks. Although this measurement is considered reliable and valid in CLT research,…

Students in the physical sciences--physics and chemistry--often take multiple-choice exams for introductory courses. Some students will write a lot on their exams, while others write very little. Does the student doing more scratch work on their exam perform better than one who does not write as much? We analyzed multiple-choice exams in physics…

Performance-based assessment is unquestionably superior to the instrumental rationality of high-stakes standardized testing and the audit culture that testing regimes inspire. It is more likely to engender opportunities to witness the un-measureable: vision, imagination, and compassion. Performance assessments must be culturally responsive in…

Educators need actionable information about student progress during the school year. This paper explores an approach to this problem in the writing domain that combines three measurement approaches intended for use in interim-assessment fashion: scenario-based assessments (SBAs), to simulate authentic classroom tasks, automated writing evaluation…

Blended learning can create flexibility for students, more efficiently utilise infrastructure, and can provide high-quality learning at scale. We investigated perceived value and learning gains associated with asynchronous eLearning and synchronous face-to-face (f2f) components of a blended learning experience. We hypothesised that individual…

This paper describes validity of quality improvement system (QIS) performance measures and longitudinal change over four years in Oklahoma 21st Century Community Learning Centers (CCLC) programs. In general, our findings indicate that the Oklahoma Afterschool Improvement Process is performing in accordance with its purposes: using accurate…

The evidence suggests that many types of summer learning programs have the potential to reduce summer learning losses and perhaps create learning gains. However, implementing a summer program does not guarantee positive effects on students' learning. A key question then is: What factors make a summer learning program effective? This article, drawn…

This is the fourth colloquium for "Contemporary Issues in Early Childhood" on the Organisation for Economic Co-operation and Development's International Early Learning and Child Well-being Study, and marks the recent publication by the Organisation for Economic Co-operation and Development of reports on the first round of this study. In…

Young girls have been dominating boys in terms of educational performance across the globe. This is a very interesting and remarkable shift observed in the global north as well as in the global south. This review paper seeks to give a succinct picture of gender differences in educational performance in the sociocultural context of various…

The release of scientific research has substantial consequences for both the research and the institution in which it was carried out. The selection of publishing methods for scientific articles, such as journal type, quartile, indexed databases, and publishing models, plays a crucial role. Various publishing models exist, including platinum,…
