Background: Phonological processing skills have been found to contribute to spelling development across different orthographies; however, less is known about the role of orthographic knowledge. This longitudinal study explores the contribution of phonological and orthographic knowledge to spelling development in a semi-transparent orthography…

This study aims to investigate the relationship between learning styles and the efficacy of routine and non-routine problem solving. It also compares these relationships with respect to routine and non-routine problem types. The study sample consisted of 356 eighth-grade students in four different schools. In this study, correlational and…

The purpose of this study was to explore career outcomes in young adulthood among adolescents with ADHD and/or high abilities. The sample included respondents who had the ability and ADHD measures from Waves 1 (1995), 3 (2002), and 4 (2009) of the National Longitudinal Study of Adolescent and Adult Health in-home questionnaire. Using multiple…

This correlative study examined the role of teacher qualities and working conditions in 4th- and 8th-grade Turkish students' mathematics achievement in TIMSS 2019. Teacher qualifications were defined based on the teacher questionnaire used in TIMSS 2019 and were discussed in three categories: personal characteristics, teacher qualifications, and…

Validity is one of the psychometric properties of the achievement tests. To determine the validity, one of the examination is item bias studies, which are based on differential item functioning (DIF) analyses and field experts' opinion. In this study, field experts were asked to estimate the DIF levels of the items to compare the estimations…

Models of achievement goals suggest that different tasks and contexts influence the goals students adopt at a given time. However, many studies of achievement goals rely on measures assessed at the class level, analyze results with a variable-centered approach, and employ self-report questionnaires, which may reduce understanding of the contextual…

Students' intelligence and self-concept of ability are critical predictors of school achievement. However, studies focusing on the relative importance of both achievement predictors have produced mixed results. To clarify these inconsistencies, the present study investigated whether the relative predictive power of students' intelligence and…

The overall objective of this study was to investigate self-efficacy, locus of control, and academic procrastination as predictors of academic achievement in students identified as gifted or non-gifted. Another purpose of the study was to analyze whether there was a difference between the self-efficacy, locus of control, and academic…

This brief examined the patterns of reading achievement using statewide data from all students (Grades 3-10) in multiple years to examine gaps based on student, school, and district characteristics. Results indicate reading achievement varied most between students within schools and that students' prior achievement was the strongest predictor of…

Purpose: This study investigated the relative utility of linguistic and nonlinguistic processing speed tasks as predictors of language impairment (LI) in children across 2 time points. Method: Linguistic and nonlinguistic reaction time data, obtained from 131 children (89 children with typical development [TD] and 42 children with LI; 74 boys and…

Background: Recent research investigating the conditions under which science teachers can successfully implement science education reforms suggests that focusing only on professional development to improve content knowledge and teaching skills--often referred to as human capital--may not be enough. Increasingly, possessing social capital, defined…

TIMSS routinely presents very powerful evidence showing that students with more positive motivation toward learning science have substantially higher achievement. The results from TIMSS 2011 are consistent with previous assessments. This study explored the predictive effects of motivation toward learning science on science achievement among…

The main objective of this study is to determine the predictive power of mathematics self-efficacy resources and perception of science self-efficacy on academic achievement. The study, adopting a relational screening model, was conducted with a total of 698 students in sixth, seventh and eighth grade level of a state secondary school. Mathematics…

In order to enhance our understanding of inter-individual differences in scholastic motivation, this study examined if self-determination predicts the school engagement of four different motivation types (MT) in a large sample of adolescent students (N = 1088) from Brandenburg, Germany: (1) peer-dependent MT, (2) teacher-dependent MT, (3)…

The present paper (1) examined variables, which could predict traditional bullying, cyberbullying, traditional victimization and cybervictimization and (2) looked at persons to examine whether academic, socio-emotional and demographic characteristics differed between traditional, cyber and mixed bullies, victims and bully-victims. A sample of…
