Objective: To examine the habit of napping and its relationship with nighttime sleep in college students. Participants: Four hundred and forty undergraduate students who responded to an anonymous online survey in April 2010. Methods: Three questions were asked to determine the frequency, length, and timing of napping during the past month. Sleep…

The purpose of this study was to examine the extent to which the pedagogical approaches used in the course were related to improvements in students' attitudes toward statistics in a Quantitative Methods course for psychology undergraduate students in a Malaysian University. The study examined whether increasing availability of the instructor and…

In the present scenario academic achievement poses a big challenge to the educationist and psychologists everywhere. It is especially of great concern in India where population explosion, multi-cultural societies and an extraordinary rush for education has led to marvelous quantitative growth of education at all the stages without consistent…

Previous research has established that attracting and retaining members is a significant challenge associated with the formation and maintenance of interest groups. Research has also established that interest groups play a significant role in the formation of educational policy. This study will attempt to provide insight as to those factors that…

Understanding of the persistence of student-athletes in athletics at the D-III level is complex. This research study investigated the issue of student-athlete retention by focusing on Division III (D-III) student-athlete persistence in athletics by asking the following research question, "To what extent do freshman student-athletes persist in…

Low-stakes assessments are commonly used in educational institutions as measures of student learning, but suffer from some threats to validity. Low-student motivation is one issue facing the validity of these assessments, as research has found student motivation to impact performance on low-stakes exams. The current study aimed to determine (a) if…

Recent events demonstrate the need for better pedagogical preparation, particularly for online instruction. There has been a sudden burst of professional development nationwide in light of the glaring need. But across higher education more broadly, questions still persist: Isn't teaching more art than science? Will faculty learn about and…

Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N =…

The van der Linden article (this issue) provides a roadmap for future research in equating. My belief is that the roadmap begins and ends with collecting auxiliary data that can be utilized to provide improved equating, especially when data are sparse or equating beyond simple moments is desired.

This article focuses on four-parameter logistic (4PL) model as an extension of the usual three-parameter logistic (3PL) model with an upper asymptote possibly different from 1. For a given item with fixed item parameters, Lord derived the value of the latent ability level that maximizes the item information function under the 3PL model. The…

There is increasing use of functional imaging data to understand the macro-connectome of the human brain. Of particular interest is the structure and function of intrinsic networks (regions exhibiting temporally coherent activity both at rest and while a task is being performed), which account for a significant portion of the variance in…

Political indicators are widely used in academic writing and decision making, but remain controversial. This paper discusses the problems related to the aggregation functions they use. Almost always, political indicators are aggregated by weighted averages or summations. The use of such functions is based on untenable assumptions (existence of…

Background: Government projections in the USA indicate that the country will need a million more science, technology, engineering, and mathematics (STEM) graduates above and beyond those already projected by the year 2022. Of crucial importance to the STEM pipeline is success in Calculus I, without which continuation in a STEM major is not…

Deaf and hard of hearing school-aged children are at risk for delayed development of emotion understanding; however, little is known about this during the preschool years. We compared the level of emotion understanding in a group of 35 4-5-year-old children who use hearing aids to that of 130 children with typical hearing. Moreover, we…

Continuing engineering education (CEE) is important to ensure engineers maintain proficiency over the life of their careers. However, relatively few studies have examined designing effective training for working engineers. Research has indicated that both learner instructional preferences and prior knowledge can impact the learning process, but it…
