There is a common belief that the more the time students spend in the classroom the more they learn; a conception which has been supported by considerable empirical research. However, most of these studies are correlational, which does not provide solid support for their conclusions. In this research work we intend to go a step further in the…

In this study, we used hierarchical linear modeling to examine restricted-use 2011 National Assessment of Educational Progress (NAEP) data to explore relationships between principal-reported time spent on the different NAEP responsibilities of mathematics coaches and specialists (MCSs) and the achievement scores of approximately 37,400…

Previous studies differed largely in their findings concerning the relationship between principal leadership and students' mathematics achievement because of the complexity of principal leadership. As Hallinger and Heck's theoretical framework showed, principal leadership was comprised setting vision/goal, school management, and school climate…

The relationship between latent trait and test-taking speed is an important area of study in assessment research. In addition to contributions of such studies to psychometrics, the factors that affect both ability and speed have implications for test development and have policy consequences especially if the tests are high stakes. This study…

Students' test anxiety is known to have significant influences on essential academic outcomes, and given the increased testing of school-aged children gender differences also appear in dimensions of test anxiety: thoughts, off-task behaviors, and autonomic reactions. This study examined: (i) whether there was a pattern of correlations existing…

To test emerging narratives of principals' direct effect on student outcomes on a large scale, this study investigates whether school principals' time use for interacting with individual students is associated with academic achievement and student safety at school. Built on recent research on principals' time use, this study explores whether…

Research Findings: This study explored the moderating effect of child competence in independent learning in relations between the amount of learning assignment, length of online learning, and parent satisfaction with children's online learning during COVID-19 imposed class suspension. The data came from an online survey conducted in Hong Kong in…

We determined the relative importance of the so-called approximate number system (ANS), symbolic number comparison (SNC) and verbal and spatial short-term and working memory (WM) capacity for mathematics achievement in 1,254 Grade 2, 4 and 6 children. The large sample size assured high power and low false report probability and allowed us to…

The present study had two aims. First, we set out to evaluate the structure of processing speed in children by comparing five alternative models: two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output response model, and a timing modality model). Second, we then used the…

Highschool homework as an integral part of the study skills benefits students' learning outcomes significantly. Consistency of completing homework contributes to rising scores in any given assignment such as quizzes, regular tests, standardized tests, etc. The purpose of homework aims at different targets and it is designed for specific groups and…

There is fear that adolescents have limited control over their digital technology use. The current research examines longitudinal (Study 1) and daily (Study 2) associations between U.S. adolescents' self-control and digital technological impairment and use. Using a large sample (N = 2,104; Wave 1: M[subscript age] = 12.36, 52% female, 57%…

The purpose of the study was to explore how fixed and modifiable family, activity, and school factors affect a student's myopia risk and severity. We used national cross-sectional data from Taiwanese children in Grades 4-6. Bivariate and multivariate analyses, including logistic and ordinary least squares regression, examined factors related to…

Explicit timing is an empirically validated intervention to increase problem completion rates by exposing individuals to a stopwatch and explicitly telling them of the time limit for the assignment. Though explicit timing has proven to be effective for groups of students, some students may not respond well to explicit timing based on factors such…

This study examines associations between leisure reading and reading skills in data of 2,525 students followed from age 7 to 16. As a step further from traditional cross-lagged analysis, a random intercept cross-lagged panel model was used to identify within-person associations of leisure reading (books, magazines, newspapers, and digital…

The authors' aim was to examine the relations among mental multiplication, working memory load (WML), and automaticity by alternating the difficulty level of task characteristics. In Experiment 1, involving 30 fifth-grade students with mixed abilities, a 2 (WML) × 2 (automaticity) design was utilized. In Experiment 2, involving 21 high-achieving…
