The aim of the present study was to examine the kinds of developmental profiles of arithmetic fluency skills that can be identified across Grades 1-9 (ages 7-16) in a large Finnish sample (n = 2,518). The study also examined whether membership in the developmental profiles could be predicted using a comprehensive set of kindergarten-age factors,…

The gender difference in reading achievement in favor of adolescent girls is a robust finding in the literature, but the evidence is mixed when considering younger children. The present study followed the development of reading skills among Finnish children (N = 1867) from kindergarten age (6 years) to 18 years of age to determine the onset of…

The present study extends research on classroom quality profiles by examining the differences between profiles with respect to children's development in pre-academic skills and motivation across the kindergarten year. Teacher-child interactions were observed in 49 Finnish kindergarten classrooms using the CLASS Pre-K instrument. Based on prior…

This longitudinal study investigated the associations among children's externalizing problems, task-avoidant behavior, and academic performance in early school years. The participants were 586 children (43% girls, 57% boys). Data pertaining to externalizing problems (teacher ratings) and task-avoidant behaviors (mother and teacher ratings) were…

The majority of previous research on academic skills, self-concept of ability and interest has deployed the variable-oriented approach and focused on self-concept, or ability, or interest only. This study examined the patterns and dynamics of pattern change in Finnish children's word reading skill, self-concept of ability and interest from…

A latent profile analysis approach was used to examine the developmental profiles of task-avoidant behaviour and reading skills in Grades 1 and 2, as well as their antecedents in kindergarten. The participants in this study were 448 children. Four different developmental profiles of task-avoidant behaviour and reading skills were identified. Our…

This study examined the extent to which first grade teachers adapt their reading instruction to the literacy skills of particular children in their classroom, and investigated whether teacher and classroom characteristics influence such adaptation. Three hundred seven Finnish children were tested with regard to their literacy skills at the end of…

This study examined cross-lagged associations between positive teacher and peer relations and academic skill development. Reading and math skills were tested among 625 students in kindergarten and Grade 4. Teacher reports of positive affect toward each student and classmate reports of peer acceptance were gathered in Grades 1-3. The results…

This study examined the associations between parenting styles, teacher interactional styles, and children's reading and spelling skills. The sample consisted of 864 Finnish-speaking children and their parents (864 mothers, 864 fathers) and teachers ("N" = 123). Children's risk for reading disabilities and reader status were assessed in…

This longitudinal study investigated the cross-lagged associations between children's academic skill development, task-avoidant behaviour in the context of homework, and parental beliefs about their child's success from kindergarten to Grade 2. The participants were 1267 children. The children's pre-skills were assessed at the end of the…

This longitudinal study examined the predictive associations between cumulative multidomain risk factors and cognitive (IQ), academic (reading fluency), and social adaptive outcomes at 8 to 9 years among 190 children with or without familial risk for dyslexia. Other risk factors included parental and neurocognitive risks assessed when the children…

The development of phonological awareness (PA) before school age was modeled in association with the development of vocabulary and letter knowledge, home literacy environment (HLE), children's reading interest, and beginning reading skill in children with and without familial risk of dyslexia. A total of 186 children were followed from birth to…

The present findings are drawn from the Jyvaskyla Longitudinal Study of Dyslexia (JLD), in which approximately 100 children with familial risk of dyslexia and 100 control children have been followed from birth. In this paper we report data on the reading development of the JLD children and their classmates, a total of 1,750 children from four…
