This paper derives efficiency scores for around 8,500 schools in 30 countries, using Programme for International Student Assessment 2012 data and a nonparametric approach called data envelopment analysis as method. On average, achievement scores of schools can be increased by 27%, holding inputs constant. Efficiency scores vary considerably both…

Abilities to encode and remember events in their spatiotemporal context (episodic memory) rely on brain regions that mature late during childhood and are supported by sleep. We compared the temporal dynamics of episodic memory formation and the role of sleep in this process between 62 children (8-12 years) and 57 adults (18-37 years). Subjects…

This study compared area lessons from Korean textbooks and US standard-based textbooks to understand differences and similarities among these textbooks, as well as how these textbooks address known learning challenges in area measurement. Several well-known challenges have been identified in previous studies, such as covering, array structure, and…

The question of renaming graduate psychology programs to psychological science is a timely and contentious issue. To better understand why some programs, but not others, are changing names, we surveyed chairpersons (Study 1) and faculty (Study 2) within graduate psychology and psychological science programs. Within psychology programs, a name…

In this article, the author highlights a recurrent issue related to the historical measurement and use of attendance data: The challenge of producing uniform and reliable records on school attendance. Comparing this issue in the late 1800s to nearly two centuries later, he observes that while the capacity for record keeping and analysis has…

The goal of this paper is to propose tables of contextual cognition as a tool for research and a model to facilitate the intercultural dialogue on science education in schools. The proposal arose from a qualitative case study, involving the use of tables of compared cognition in biology classes in a Brazilian public school. The results indicate…

This study aims to observe the possible negative effects that might occur on bio-chemistry and hemogram values of tennis players during the intense competition period by comparing the blood values of pre-competition period with 10 days of intense exercise. Blood samples were obtained from tennis team players who do not have any specific health…

This article offers a systematic review of the evolution of research impact assessment in Australia and the UK. We consider its inception and detail the development of relevant policy and procedures in each country. The article sets out the results of a comparative analysis of public policy documents, newspaper commentary, and academic literature…

There is a call for more transdisciplinary (TD) research, from academia, society, and funding agencies. Consequently, the field of TD research is searching for ways of proving the value and providing evidence to support the effectiveness of such research. The main challenge for evaluating TD research is attribution, that is how to link societal…

This study compared college students' (N = 260) responses on a simple dichotomous screening measure and 2 behavior checklists. Seventy-nine participants (30.4%) screened positive (i.e., endorsed nonsuicidal self-injury [NSSI] behavior) on at least 1 measure, and 37 (46.8%) screened positive on the simple screen. Participants who screened positive…

Background: Takotsubo Syndrome is a condition that causes impairment in cardiac function in the absence of significant causative coronary artery disease. Takotsubo Syndrome is most commonly reported in older women, has identical presenting symptoms to acute coronary syndrome (ACS), but differs in cause, management and outcomes. Ongoing symptoms…

While hierarchical machine learning approaches have been used to classify texts into different content areas, this approach has, to our knowledge, not been used in the automated assessment of text difficulty. This study compared the accuracy of four classification machine learning approaches (flat, one-vs-one, one-vs-all, and hierarchical) using…

Given the widespread use of non-experimental (NE) methods for assessing program impacts, there is a strong need to know whether NE approaches yield causally valid results in field settings. In within-study comparison (WSC) designs, the researcher compares treatment effects from an NE with those obtained from a randomized experiment that shares the…

We share a subset of the 41 underlying strategies that comprise five ways of reasoning about integer addition and subtraction: formal, order-based, analogy-based, computational, and emergent. The examples of the strategies are designed to provide clear comparisons and contrasts to support both teachers and researchers in understanding specific…

This study aims to identify how feasible it is to use comparative judgement (CJ) and student judges to assess the writing performance of English language learners. For this purpose, 35 paragraphs written by the students who were enrolled in a freshman Academic Writing course at a semi-private university located in the Turkish Republic of Northern…
