Applying optimal stimulation theory, the present study explored the development of sustained attention as a dynamic process. It examined the interaction of modality and temperament over time in children and adults. Second-grade children and college-aged adults performed auditory and visual vigilance tasks. Using the Carey temperament…

Data from a population-based repository in Manitoba showed that students who are male, young for grade, and in Grades 1, 2, 7, and 8 were the most likely to be retained. After controlling for key student factors including socioeconomic status, school changes, and key school characteristics including stability of the student body, retention was a…

A total of 46 children in Grades 2 and 3 with low word-level skills were randomly assigned to 1 of 2 groups that received supplemental phonics-based reading instruction. One group received intervention October through March (21.5 hours), and one group served as a control from October through March and later received intervention March through May…

This study examined the effects on 6- and 8-year old children (n = 160) of rejection versus acceptance by an initial group, the reason for the rejection or acceptance (personal versus category-based), and the norms (inclusion versus exclusion) of a new group to which the children were assigned, on their negative affect and attitudes towards the…

The research deals a problem of primary pupils' preconceptions about a child prenatal development. Even the pupils cannot experience the phenomenon and can get only mediate information; their idea about the prenatal development is quite well constructed. The quality of the preconceptions depends mainly upon variety of informational sources kept at…

English spelling is highly inconsistent in terms of simple sound-to-spelling correspondences but is more consistent when context is taken into account. For example, the choice between "ch" and "tch" is determined by the preceding vowel ("coach," "roach" vs. "catch," "hatch"). We investigated children's sensitivity to vowel context when spelling…

This study focuses on the shared variance between reading comprehension and word-level reading skills in a population of 534 Greek children in Grades 2 through 4. The correlations between measures of word and pseudoword accuracy and fluency, on the one hand, and vocabulary and comprehension skills, on the other, were sizeable and stable or…

The present study aimed to determine which anxiety symptoms in children are associated with teacher awareness and whether teacher awareness differs according to student age and gender. The Multidimensional Anxiety Scale for Children (MASC) was completed by 453 second through fifth grade students and teachers nominated the three most anxious…

In the present study, the authors investigated age differences in children's understanding (a) that a person's behavior may contribute to the formation of a shared opinion within the peer group and (b) that origins of a reputation can be direct or indirect. The authors read stories in which a target character engaged in either prosocial or…

Previous research (e.g., De Bock, 2002) has shown that--due to the extensive attention paid to proportional reasoning in elementary and secondary mathematics education--many students tend to overrely on proportional methods in diverse domains of mathematics (e.g., geometry, probability). We investigated the development of misapplication of…

Two experiments examined kindergartners', first graders', and second graders' numerical estimation, the internal representations that gave rise to the estimates, and the general hypothesis that developmental sequences within a domain tend to repeat themselves in new contexts. Development of estimation in this age range on 0-to-100 number lines…

In this article, I present a study conducted with 10 Southeastern US early childhood teachers on their views concerning problem behaviour, in general, and the practice of diagnosis and pharmaceutical treatment for Attention/Deficit Hyperactivity Disorder (ADHD), in particular. Themes that emerged from the interview data included: (1) teachers'…

In a pair of recent studies, Fryer and Levitt (2004a, 2004b) analyzed the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) to explore the characteristics of the Black-White test score gap in young children. They found that the gap grew markedly between kindergarten and the third grade and that they could predict the gap from…

The aim of the present study was to investigate the performance in arithmetic related to achievement levels in reading and mathematics. Basic arithmetical facts and multi-step calculations were examined. The participants were 941 pupils aged 8 (N = 415), 10 (N = 274) and 13 (N = 252) years. The pupils were divided into four groups by standardized…

This article describes a unit of instruction designed to promote algebraic thinking in second graders. Students examined second- and fourth-grade students' ages and heights on a table and graph and described the patterns that they observed in the data.
