The current research investigated the variability of school effects on intelligence development in considering two economically and socially distinct groups of children. The data came from a nationally representative sample of primary school children from urban and rural areas of China. Two standardised reasoning tests were used to assess fluid…

Technology change is a key factor in the change of lifestyles in the society in the 21st century. The rapid alternation of computers, the Internet, and smart phones has human beings live in the information-built environment. Information technology is also applied to measure the modernization of a nation. A lot of countries even list computer…

The authors examined the association between relational health and student adjustment to college. Data were collected from 138 undergraduate students completing their 1st semester at a large university in the mid-southern United States. Regression analysis indicated that higher levels of relational authenticity were a predictor of success during…

E. A. Hanushek points out in this commentary that applied researchers in education have only recently begun to appreciate the value of international assessments, even though there are now 50 years of experience with these. Until recently, these assessments have been stand-alone surveys that have not been linked, and analysis has largely focused on…

The second law of thermodynamics has various formulations. There is the "Clausius formulation," which can be stated in a very intuitive way: "No process is possible whose sole result is the transfer of heat from a cooler to a hotter body." There is also the "Kelvin-Plank principle," which states that "no cyclic…

Students' lives outside of college can have dramatic effects on academic outcomes (e.g., grades, persistence, graduation). However, the manner in which students' lives outside of college are referenced in college-effects models suggests some uncertainty among scholars as to which, and how, student experiences outside of an institution affect…

The ability to act jointly with another person is a fundamental requirement for participation in social life. The current study examines the development of action planning in a joint action context. In 4 experiments, 3-, 5-, and 7-year-old children as well as a group of adults (n = 196) interacted with another person to operate a novel apparatus.…

Monte Carlo simulations (MCSs) provide important information about statistical phenomena that would be impossible to assess otherwise. This article introduces MCS methods and their applications to research and statistical pedagogy using a novel software package for the R Project for Statistical Computing constructed to lessen the often steep…

We conducted an annual survey of undergraduate students taking finance courses over the past 5 years (2009-2014). Our results showed that although more than 70% of students considered the financial planning profession to some extent, the percentage of students who had seriously considered it declined over time, despite the increasing number of new…

Meta-analyses are typically used to estimate the overall/mean of an outcome of interest. However, inference about between-study variability, which is typically modelled using a between-study variance parameter, is usually an additional aim. The DerSimonian and Laird method, currently widely used by default to estimate the between-study variance,…

Students can struggle to understand and use terms that describe probabilities. Such struggles lead to difficulties comprehending classroom conversations. In this article, we describe some specific misunderstandings a group of students (ages 11-12) held in regard to vocabulary such as "certain", "likely" and…

In this work, we have investigated text readability in Bangla language. Text readability is an indicator of the suitability of a given document with respect to a target reader group. Therefore, text readability has huge impact on educational content preparation. The advances in the field of natural language processing have enabled the automatic…

Power analysis is a fundamental prerequisite for conducting scientific research. Without power analysis the researcher has no way of knowing whether the sample size is large enough to detect the effect he or she is looking for. This paper demonstrates how psychometric factors such as measurement error and equating error affect the power of…

Purpose: The aim of this study was to compare the electromyographic patterns of the lower limb muscles during a golf swing performed by low- and high-handicap golfers. Method: Ten golfers (5 low- and 5 high-handicap) performed 8 swings using a 7-iron. Surface electromyography (EMG) was recorded for the following lower limb muscles on both sides:…

The present study examined the "visual scanning hypothesis", which suggests that fluent oculomotor control is an important component underlying the predictive relationship between Rapid Automatized Naming (RAN) tasks and reading ability. Our approach was to isolate components of saccadic planning, articulation, and lexical retrieval in 3…
