This methodological guidance article discusses the elements of a high-quality meta-analysis that is conducted within the context of a systematic review. Meta-analysis, a set of statistical techniques for synthesizing the results of multiple studies, is used when the guiding research question focuses on a quantitative summary of study results. In…

The detailed analysis and scoring of concept maps may not be necessary in order for students to gain from their use in the classroom. A simplified recognition of different types ('species') of map may increase the likelihood of teachers employing maps in their classrooms so that more teachers and students might benefit from concept mapping on a…

Males (n = 29) and females (n = 34) performed vertical jumps. Jump height was estimated from force platform data using five numerical methods and compared using intraclass correlation ([rho]), and linear and rank regression standard error of estimate ("SEE"). Take-off velocity plus center of mass height at take-off and mechanical work…

The purpose of this study was to develop triangulation coding methods for a large-scale action research and evaluation project and to examine how practitioners and policy makers interpreted both convergent and divergent data. We created a color-coded system that evaluated the extent of triangulation across methodologies (qualitative and…

This article examines factors that could have influenced whether evaluations of U.S. government--funded foreign assistance programs completed in 2015 had considered unintended consequences. Logit regression models indicate that the odds of considering unintended consequences were increased when all or most of seven standard data collection methods…

This essay provides advice for effectively reviewing conference proposals, including how to write comments that are helpful to proposal authors, how to use the "Comments to Program Chair" box, and issues to consider when assigning proposal ratings and recommending acceptance or rejection. Several benefits of reviewing proposals are…

The purpose of this article is to share ideas from "5x5x5=creativity," a research initiative established in Bath (UK) in 2000, with the aim of developing and embedding a creative and reflective pedagogy in schools and early years settings. "5x5x5=creativity" research, in partnership with schools, educators, artists, creative…

Examination of my students' individual gains on the Force Concept Inventory (FCI) over the course of several semesters led to the realization that student pretest knowledge on certain key questions appeared to be correlated to enhanced gain during the class. Acting under the hypothesis that early intervention aimed at helping the class perform…

The idea that the emerging global society is also the age of the 'pictorial turn' is one in which the use of visual historical sources (VHS) in the teaching and learning of History in English secondary schools is situated. Yet there has been little research conducted into how such sources are experienced by teachers and students in the classroom,…

This paper describes an upper-division undergraduate exercise involving the synthesis and iodometric and infrared spectroscopic analysis of the peroxide double salt [Zn(NH[subscript 3])[subscript 4]][Mo(O[subscript 2])[subscript 4]]. Here, iodometric methods are employed to determine the peroxide content of the compound, a procedure widely used…

This paper describes a first-year undergraduate exercise involving the synthesis of an "unknown" polyiodide salt, (NMe[subscript 4])[I[subscript 5]], and the determination of its formula using the classic iodine-thiosulfate (iodometric) titration. The exercise introduces students to simple synthetic and titrimetric techniques, assists…

Competent writing eludes many school children and adolescents, especially those with developmental language and reading disorders. Language sample analysis (LSA) of writing is a powerful but underused assessment tool that can also inform instruction. Similar to LSA of oral language, writing has been analyzed at word, sentence, and text levels…

Variability is common in language sample analysis (LSA), arising from personal factors such as age or level of education, or from factors within the text such as its length and purpose. Variability can affect interpretation of results in clinical practice and research studies, as well as the ability to detect change in individuals over time. This…

The current environmental crisis has mainly a human-induced origin. In this regard, technical and vocational (T&V) graduates have an important role in the optimal use of environment and resources. Therefore, this research intends to find the best teaching method of education for sustainable development (ESD) in order to improve the behavior of…

In times of social crises, Public Religious Pedagogy is emerging as "a new paradigm in the field of Religious Pedagogy" (Manfred L. Pirner). This paper aims to strengthen this approach through a critical review. To achieve this, the theoretical foundations of Public Religious Pedagogy will be examined more closely in order to investigate…
