Age-classes are a salient feature of modern schooling. Yet how did age-grouping come to prevail in entire school systems? And how was this form of grouping related to educational and pedagogic discussions at the time of its emergence? The article addresses these issues by looking at the historical context within which age classes came to a…

Globally, science interest in diminishing among students, and as a result the science career field has begun to suffer from a lack of science career aspirations. The issue is especially relevant in developed countries, such as the United States, Japan, and South Korea, because of their policies and efforts to promote science and science education…

Purpose: We investigated developmental differences in a dual task involving rhyming and tone judgment/decisions and the effects of varying cognitive demands on task performance. Method: Participants were 7- to 11-year-olds, 12- to 15-year-olds, and adults between 18 and 40 years (n = 19 per group). The rhyming task consisted of three stimuli…

Data from the standardization sample of the Woodcock-Johnson Psychoeducational Battery--Third Edition (WJ III) Cognitive standard battery and Test Session Observation Checklist items were analyzed to understand the relationship between g (general mental ability) and test session behavior (TSB; n = 5,769). Latent variable modeling methods were used…

Annual age grouping of children according to their birth year is a common practice of the educational systems of many countries. This variation in birth dates among children grouped in the same generation is known as relative age and its implications on different developmental outcomes are referred to as relative age effects (RAEs). The previous…

The purpose of this study was to investigate the preferred method of learning about heart disease by adult learners. This research study also investigated if there was a statistically significant difference between race/ethnicity, age, and gender of adult learners and their preferred method of learning preventative heart disease care. This…

By utilizing inquiry processes, such as observing and questioning, young children learn to investigate and use evidence to evaluate information. Through intersubjectivity, or social collaboration and mutual focus, children coconstruct an understanding of the world. Children's inquiry and intersubjectivity were observed in a range of activities in…

This study investigated a sample of California elementary, intermediate, and high school employed teachers (N = 247) to assess the effects of retirement perceptions on career commitment among teachers who are in different age groupings. Using path analysis, the influence of five retirement perceptions variables was examined: concerns about…

In sports, the relative age effect (RAE) refers to performance disadvantages of children born late in the competition year compared to those with birthdays soon after the cutoff date. This effect is derived from age grouping, a strategy commonly used in youth sport programs. The purpose of age grouping is to decrease possible cognitive, physical,…

The Adult-Oriented Sport Coaching Survey (AOSCS) is a valid and reliable measure of coaches' and Masters athletes' perspectives of how often adult-oriented coaching practices are used. However, Masters athletes' heterogenous traits have been acknowledged as barriers to generalizing research findings on coaching behaviors. Therefore, this study…

Annual age cohort groupings promote relative age effects (RAEs), which often, inadvertently, create participation and attainment biases between relatively older and younger players within the same age cohort. In a globally evolving sport, women's rugby team selection practices may potentially bypass qualified players as a result of maturational…

This study examines the differences that exist among various age cohorts attending a post-secondary educational institution. Respondents were from the New Brunswick Community College's six separate campuses (n = 251). Significant differences were found to exist predominantly around social and family issues. Although differences did appear based on…

Grouping children of different ages in the same preschool classroom (i.e., mixed age) is widespread, but the evidence supporting this practice is mixed. A factor that may play a role in the relation between classroom age composition and child outcomes is peer skill. This study used a sample of 6,338 preschoolers (ages 3-5) to examine the influence…

Relative Age Effects (RAEs), describing attainment inequalities as a result of interactions between biological age and age-grouping procedures, have been demonstrated across many sports contexts. This study examined whether an additional individual characteristic (i.e., handedness) mediated RAEs in tennis. Relative age and handedness distributions…

The study examined the impact of students' absolute age-position at the time of testing by grade level and gender on their achieved level of mathematics, reading and science performance. An analysis was conducted based on a sample of 11,500 15-year-old pupils in the United Arab Emirates who participated in the OECD's Programme for International…
