The objective of this study is to empirically compare alternative meta-analytic methods for combining dose-response data from epidemiological studies. We identified meta-analyses of epidemiological studies that analyzed the association between a single nutrient and a dichotomous outcome. For each topic, we performed meta-analyses of odds ratios…

In this third and concluding discussion on analytics, the author notes that we live in an information culture. We are accustomed to having information instantly available and accessible, along with feedback and recommendations. We want to know what people think and like (or dislike). We want to know how we compare with "others like me."…

This study examined the differing conclusions one may come to depending upon the type of analysis chosen, hierarchical linear modeling or ordinary least squares (OLS) regression. To illustrate this point, this study examined the influences of seniors' self-reported critical thinking abilities three ways: (1) an OLS regression with the student…

Simple numerical data analysis is described, using a standard spreadsheet program, to determine distance, velocity (speed) and acceleration from voltage data generated by a skateboard/longboard speedometer (Hare 2012 "Phys. Educ." 47 409-17). This simple analysis is an introduction to data processing including scaling data as well as…

The two most commonly used parameters of crater shape are the diameter of the rim crest (D) and the floor to rim depth (d). However, the widespread application of d/D has limitations. This paper provides high ability students with the opportunity to use real scientific data to derive the depth/diameter ratio of rimmed (d:D) and rimless craters…

The present study investigated the problem-solving performance of 101 university students and their interactions with a computer modeling tool in order to solve a complex problem. Based on their performance on the hidden figures test, students were assigned to three groups of field-dependent (FD), field-mixed (FM), and field-independent (FI)…

The purpose of this study was to investigate the effect of complex structure on dimensionality assessment in noncompensatory multidimensional item response models using dimensionality assessment procedures based on DETECT (dimensionality evaluation to enumerate contributing traits) and NOHARM (normal ogive harmonic analysis robust method). Five…

The demand for master's level counseling scholarship is on the rise as a call for evidenced based practices persist (Benishek, 1998; Briggs & Pehrsson, 2008; Huber & Savage, 2009). Although there is a demand to increase the amount of counseling produced scholarship, little examination exists regarding how the profession can begin to…

A dissertation study looking at preservice teachers' alternative conceptions in earth science was completed by one of the authors. The data used for this study from the dissertation were a series of eleven interviews. (Purpose) The authors of this manuscript wanted to provide more in-depth analysis of these interviews, specifically to provide a…

This report summarizes the outcomes of a discussion among a group of State and district officials, teachers and principals, and external experts in educator evaluations and strategic communications who gathered in the District of Columbia to examine early results from evaluation systems in two States.

In April 2010, President Obama issued a directive to the Secretary of Health and Human Services (HHS) regarding patient visitation, advance directives, and other initiatives to improve the lives of lesbian, gay, bisexual, and transgender people and their families. The HHS response to this directive has implications for hospital social workers. The…

Educational legislation and policy can lead to effective educational practices, especially for student populations that have had equal access to education addressing their needs, such as students with disabilities and gifted students. This study was an examination of state legislation and policy related to twice-exceptional learners in the United…

This paper presents the findings of a mixed methods study conducted in the context of Higher Education Institutions (HEIs). More specifically, it focuses on the staff development needs of tutors who teach in blended and online environments, the ways HEIs in the United Kingdom (UK) address these needs and institutional issues around the deployment…

Programmatic-level comparisons are made between the certified public accountant (CPA) exam outcomes of two types of accounting programs: online or distance accounting programs and face-to-face or classroom accounting programs. After matching programs from each group on student selectivity at admission, the two types of programs are compared on CPA…

Considering scoring validity as encompassing both reliable rating scale use and valid descriptor interpretation, this study reports on the validation of a CEFR-based scale that was co-constructed and used by novice raters. The research questions this paper wishes to answer are (a) whether it is possible to construct a CEFR-based rating scale with…
