This paper details the challenges encountered by authors summarizing evidence from a primary study to describe a treatment's effectiveness using an effect size (ES) estimate. Dilemmas that are encountered, including how to calculate and interpret the pertinent standardized mean difference ES for results from studies of various research designs,…

A hotly debated topic in oropharyngeal dysphagia is the Clinical Swallowing Examination's (CSE) importance in clinical practice. That debate can profit from the application of evidence-based medicine's (EBM) principles and procedures. These can guide both appropriate data collection and interpretation as will be demonstrated in the present report.…

The article presents empirical evidence for the effectiveness and efficiency of a modified version of Trochim's (1989a, b) concept mapping approach to define the characteristics of an adaptive learning environment. The effectiveness and the efficiency of the method are attributed to the support that it provides in terms of elicitation, sharing,…

The data discussed in this paper are from the television game show "Friend or Foe", and can be used to examine whether age, gender, race, and the amount of prize money affect contestants' strategies. The data are suitable for a variety of statistical analyses, such as descriptive statistics, testing for differences in means or proportions, and…

We live in an era where IC&T generates numerous transformations to the classic way of learning. The most known results of these transformations concretise in two means of learning through IC&T: e-learning and computer assisted learning. Just like the classical ones, these models assume the existence of an efficient learning process based…

Science tends to find a solution to the problem of the unreliability of human perception by understanding objectivity as the absence of subjectivity. However, from a phenomenological point of view, subjectivity is not so much a problem as an inevitable starting-point. That does not mean that the problem of the correctness of people's accounts of…

Educational improvement through data-based decision-making using high-quality data is a longstanding goal of policymakers and practitioners, and ensuring the quality of the evidence available to inform such decisions is a key part of the No Child Left Behind Act of 2001. The evidence-based education that such initiatives promote involves the…

The purpose of this study was to understand the relationship of student entry data to current English language learning status. District-level data was obtained for 1,942 K-5 native Spanish-speaking elementary-level students administered the oral Spanish and English Language Assessment Scale (Pre-LAS). Canonical correlation analysis was used to…

This article examines how service-learning provides undergraduate teacher candidates opportunities to cultivate deeper understandings of diversity, social justice, and themselves. Participants were from a mid-Atlantic university and a rural southeastern university. Although from different regions, the teacher candidates shared predominantly White,…

Some scholars have suggested that a negative consequence of strengthening child support enforcement is to encourage fathers to shift from regular sector to underground employment. We employ data from the Fragile Families and Child Wellbeing Study to investigate the relationship between the strength of child support enforcement (CSE) and levels of…

This article presents a learning cycle with the aim of helping students understand the evidentiary basis of scientific claims. Students consider data and interpretations as used to support contradictory views in the debate surrounding the causal relationship between human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS).…

This present study investigated engineering students' conceptions and misconceptions related to derivative, particularly interpreting the graph of a function and constructing its derivative graph. Participants were 147 first year engineering students from four universities enrolled in first year undergraduate calculus courses with or without the…

There is a cross-national trend towards unified curriculum and qualifications frameworks in upper secondary education, but such reforms face epistemological, political and institutional barriers and "unification" remains a contested issue in many countries, including England. This article examines the experience of the Scottish Higher…

Prior research on oppositional culture theory has generally focused on beliefs about the opportunity structure, or the "acting white" hypothesis, as an explanation for racial differences in school achievement. However, little attention has been given to the mechanism by which these beliefs affect achievement: schooling behaviors. The authors posit…

This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…
