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…

Effective regulation of motivation can be theoretically explained by both the extent of motivational regulation strategies used (quantity) and their optimal implementation (quality). Researchers have not yet analysed the significance of both aspects for learning success simultaneously. In the present study, 188 students were presented with…

The aim of the present study was to examine the interplay between test anxiety (i.e. worry and emotionality) and learned helplessness in a sample of adolescents (N = 845, aged 13-17 years) in secondary schools in Germany. In accordance with the buffering hypothesis, it was hypothesised that the detrimental association between both components of…

This study examined the incremental validity of different information and communication technologies (ICT)-related person characteristics over and above intelligence and and prior achievement when predicting ICT literacy across a period of three years. Relative weights analyses were performed to determine the relative contribution of each…

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…

Based upon self-concept and self-determination theory, the present study aimed to examine the measurement separability of young children's math self-concept (MSC) and six specific types of motivation, namely, intrinsic motivation (INTR), integrated motivation (INTEG), identified motivation (IDENT), introjected motivation, extrinsic motivation…

In this study, we investigated effects of the proportion of language minority students in classrooms on the development of students' intrinsic motivation in language lessons and the mediating role of instructional climate (e.g., teacher support, focus on student interests). In addition, we explored the interaction between the proportion of…

Self-concepts of ability (SCA) and intrinsic task values (ITV) are key determinants of students' choice of study program and dropout. Both constructs are multidimensional (i.e., specific to curricular learning content) and hierarchically structured (i.e., aggregate into one or more higher-order factors). The present study investigated German…

Expectancy-value theory of achievement motivation identifies two classes of beliefs that are important predictors of educational choices and achievement: expectancies and values. It is well known that high achieving peers can have a negative impact on self-concept and other measures of expected success: holding individual achievement constant,…

Introduction: Multiple imputation (MI) is one of the most highly recommended methods for replacing missing values in research data. The scope of this paper is to demonstrate missing data handling in SEM by analyzing two modified data examples from educational psychology, and to give practical recommendations for applied researchers. Method: We…

Reading comprehension is a self-regulated activity that depends on the proactive effort of the reader. Therefore, the authors studied the effects of personal initiative (PI) on the development of reading comprehension, mediated by reading strategy knowledge. Structural equation modelling was applied to a longitudinal study with two data waves…

It is now well known that adolescence is frequently marked by a decline in students' achievement motivation, which in turn is often associated with a decline in individual school self-concept. Less is known about the mediating role of socio-motivational support in the association between individual school self-concept and achievement motivation.…

This study investigated the relationship between teachers' beliefs about gifted students' characteristics compared to students with average-ability and the teachers' motivation (i.e., enthusiasm, self-efficacy). We investigated pre-service teachers' beliefs and motivational orientations as substantial components of their professional competencies…

Although positive teacher-student relationships are known to aid students' academic self-regulation, the emotional aspects of teacher liking are often neglected within research. The present study used a large sample of seventh- and eighth-grade students (N = 1,088; M[subscript Age] = 13.7) in secondary schools in Germany to investigate whether the…

This study addressed the role of reading motivation as a potential determinant of losses or gains in reading competence over six weeks of summer vacation (SV). Based on a sample of 223 third-grade elementary students, structural equation analyses showed that intrinsic reading motivation before SV contributed positively to both word and sentence…
