To examine developmental processes, intervention effects, or both, longitudinal studies often aim to include measurement intervals that are equally spaced for all participants. In reality, however, this goal is hardly ever met. Although different approaches have been proposed to deal with this issue, few studies have investigated the potential…

Based on control-value theory (CVT), we examined longitudinal relations between students' control and value appraisals, three activity-related achievement emotions (enjoyment, anger, and boredom), and math achievement (N = 1,716 fifth and seventh grade students). We assessed appraisals and emotions with self-report measures of perceived competence…

The goal of the present study was to investigate the mediating effects of reading amount and metacognitive knowledge of strategy use in the relationship between intrinsic motivation and reading comprehension among secondary school students. We hypothesized that reading amount and metacognitive knowledge of strategy use in Grade 6 will mediate the…

The purpose of the study was to determine the level of the relationship among Turkish elementary school students' personal epistemologies, motivation, learning strategies, and achievements in science. A total of 322 fifth-grade students participated in the study. Results from the structural equation modeling showed that students' personal…

In order to advance our understanding of educational processes, we present a tutorial of intraindividual variability. An adaptive educational process is characterised by stable (less variability), and a maladaptive process is characterised by instable (more variability) learning experiences from one learning situation to the next. We outline step…

The contributions of academic achievement motivation and social status to peer-reported academic influence were explored in a sample of 322 children in grades three through five. Latent moderated structural equation modeling indicated that children who value academics are more likely to be rated by peers as academically influential. Social status…

Using an expectancy-value framework, the present investigation is the first to explore the generality of this theorizing and research in the emerging regional context of the Caribbean. Given high underachievement in the Caribbean region, we addressed the need to better understand the role of engagement in students' academic motivation and…

Background: In recent research, affective learning environments and affective support have been receiving increasing attention for their roles in stimulating students' learning outcomes. Despite its raising importance, little is known about affective support in educational contexts in developing countries. Moreover, international student…

Background: Despite devotion of substantial resources and effort to increase parent/school partnerships, gaps remain between policy rhetoric and practice, especially in high-poverty communities. Current research focuses on parent involvement or effects of parent motivational beliefs on parent choice for behavior; however, it does not address the…

Although many studies have documented developmental change in mathematics motivation, little is known about how these trends predict math performance. A sample of 288 participants from the United States reported their perceived math ability, math utility value and math interest in 5th, 7th and 9th grades. Latent growth curve models estimated…

The aim of the study was to investigate the relationships between elementary students' reported use of self-regulatory strategies in mathematics and their motivational and affective determinants. Participants of the study were 344 fifth- and sixth-grade Greek students. Students were asked to complete self-reported measures regarding the strategies…

Motivations for and positive attitudes toward physical activity (PA) developed during childhood are likely to be carried over to adulthood. The purpose of this study was to examine the relationship between three psychological needs satisfaction, motivational regulations in physical education (PE), and attitudes toward participation in leisure-time…

This study examined the role of reading amount as a mediator of the effects of intrinsic and extrinsic reading motivation on higher order reading comprehension (comprised of paragraph-and passage-level comprehension) in a sample of 159 fifth-grade elementary students. A positive association between intrinsic reading motivation and reading amount…

Student motivation may have significant influences on essential academic outcomes. However, students' motivation may decline as they grow older. This study examined six motivation constructs (self-efficacy, interest, mastery goal orientation, engagement, avoidance coping, and effort withdrawal) of students from 78 schools in Singapore (N = 4214)…

This study investigated the relationship among critical motivational variables and mathematics achievement as middle grades students engaged in a reform-oriented curriculum, "Mathematics in Context." We tested 327 students in fifth, sixth, and seventh grade before and after two years of implementation. We performed a path analysis with…
