Recently, Nissen et al. argued in this journal for the use of Cohen's d, in place of the more commonly used normalized gain, in the analysis of preinstruction and postinstruction scores on concept inventories used to measure the effectiveness of instruction. Their reason for advocating such a change is that they say normalized gains are…

The design of the Cognitive Tutor Algebra I (CTA1) intelligent tutoring system assumes that students work through sections of material following a pre-specified order, and only move on from one section to the next after mastering the first section's skills. However, the software gives teachers the flexibility to override that structure, by…

To plan cluster-randomized trials with sufficient statistical power to detect intervention effects on student achievement, researchers need multilevel design parameters, including measures of between-classroom and between-school differences and the amounts of variance explained by covariates at the student, classroom, and school level. Previous…

Objective: This study explored maternal knowledge of pertussis and Tdap vaccine and the use of a Tdap Vaccine Information Statement (VIS) to improve that knowledge. Design: Prospective cohort study. Setting: Two outpatient obstetric clinics at a US academic medical centre. Methods: An electronic survey was administered to pregnant women who…

The present study furthered the concept of simulation-based medical education by applying a personalized active learning component. We tested this novel approach utilizing a noninvasive hemodynamic monitor with the capability to measure and display in real time numerous hemodynamic parameters in the exercising participant. Changes in medical…

Background: Training middle school students to perform hands-only cardiopulmonary resuscitation (HOCPR) is a potential method to increase overall rates of bystander cardiopulmonary resuscitation (CPR). We aimed to examine the feasibility of teaching this population CPR using teacher-implemented education sessions guided by American Heart…

Research focused on the relationship of emotional intelligence (EI) to academic and professional success in education, and whether and how it might be taught and learned, is inconclusive. The purpose of this study was to examine the degree to which undergraduate music education majors experienced a change in EI after implementing strategies from…

This study examined whether children 4- and 5-years-old (N = 156) can revise a physical science misconception from different types of picture books. A realistic fiction book and informational book with identical images matched in word count and reading difficulty level were compared to a control book about plants. In the pretest and posttest,…

This experimental study examines the role of oral and written repetition strategies in consolidating new vocabulary in the classroom context. The participants in this study were divided into three treatment groups: oral, written and oral+written. A pretest and three delayed post-tests given at one day, one week and six weeks intervals were…

Purpose: Although motor skill interventions often improve fundamental motor skills (FMS) during preschool, the extent of individual children's success in development of FMS still varies among children receiving the same intervention. Temperament is multifaceted and includes negative affect (high levels of frustration or anger), effortful control…

This research examined the effects of structured group supervision (SGS) on counsellors' self-efficacy, counselling competency, and job involvement in Singapore. Twenty-one counsellors participated in six, 3- hour SGS sessions over 12 weeks with one qualified counselling supervisor. The counsellors had at least six months' experience working as…

We compared students' performance on a paper-based test (PBT) and three computer-based tests (CBTs). The three computer-based tests used different test navigation and answer selection features, allowing us to examine how these features affect student performance. The study sample consisted of 9,698 fourth through twelfth grade students from across…

In recent years, a number of insights have been gained into the cognitive processes that explain how individuals overcome misconceptions and revise their previously acquired incorrect knowledge. The current study complements this line of research by investigating the moment-by-moment emotion processes that occur during knowledge revision using a…

Outdoor adventure education (OAE) is philosophically rooted in Western values, yet it has been implemented in non-Western cultures, such as East Asia. This paper examines how OAE functions in East Asia, through data from Hong Kong. Although some cultural differences are clear, there is no compelling evidence that OAE cannot provide benefits in…

The Implicit Association Test (IAT) is increasingly used in developmental research despite minimal evidence of whether children's IAT scores are reliable across time or predictive of behavior. When test-retest reliability and predictive validity have been assessed, the results have been mixed, and because these studies have differed on many…
