There is fear that adolescents have limited control over their digital technology use. The current research examines longitudinal (Study 1) and daily (Study 2) associations between U.S. adolescents' self-control and digital technological impairment and use. Using a large sample (N = 2,104; Wave 1: M[subscript age] = 12.36, 52% female, 57%…

The aim of this study was to examine the contribution of transcription skills, oral language skills, and executive functions to growth in narrative writing between fourth and sixth grade. While text length and story content of narratives did not increase with age, syntactic complexity of narratives showed a clear developmental progression. Results…

Learning to write in middle school requires the expansion of sentence-level and discourse-level language skills. In this study, we investigated later language development in the writing of a cross-sectional sample of 235 upper elementary and middle school students (grades 4-8) by examining the use of (1) lexico-grammatical forms that support…

The acquisition by preadolescent and late adolescent students of two kinds of information from brief texts was assessed: premise information and inference information. Age differences were obtained in inference performance. However, when the texts provided sufficient contextual support, the inference performance of preadolescents was equivalent to…

Age-related changes in children's performance on simple division problems (e.g., 6 divided by 2, 72 divided by 9) were investigated by asking children in Grades 4 through 7 to solve 32 simple division problems. Differences in performance were found across grade, with younger children performing more slowly and less accurately than older children.…

The developing relationship between children's metacognition and reading comprehension was examined for 87 third and 84 fifth graders. Students using the experimental curriculum--Informed Strategies for Learning--made significant gains in metacognition and the use of reading strategies when compared with control students. (TJH)

Fourth and sixth grade children differing in reading proficiency read and commented on brief expository passages containing three different types of embedded problems (nonsense words, prior knowledge violations, and internal inconsistencies). Half of the children were specificially instructed as to the types of standards they should apply in order…

Preschool children (N=23) and fifth-grade children (N=23) and their mothers judged the acceptability of corporal punishment as a function of the type of transgression (acting danerously, violating a social rule, or violating a moral precept) and discipline agent. Children of both ages and their mothers discriminated among different types of…

Being older rather than younger than most of one's classmates is presumed to provide benefits to students throughout elementary and secondary school. The present study investigated this age status hypothesis among students before and after the transition to middle school in sixth grade with respect to school strain, self-esteem, and grade point…

A total of 230 second through fifth grade boys and girls from five private schools in the San Francisco Bay area were asked to keep a record of the books they read for pleasure over the period of a month to determine whether there were differences between the books chosen across the grades and between sexes. The students recorded the books on a…

Predicting that when presented with a general context children and adults would produce different specific inferences, a study examined children's and adults' script representations of a common event and the use of representation in comprehension. In the first phase of the study, 23 fourth grade and 48 college students were asked to generate…

The development of conceptual knowledge about the earth among 60 elementary school students in grades 1, 3, and 5 was studied through questions about its shape. In the process of knowledge acquisition, children appear to modify their initial models to make them more consistent with the culturally accepted model. (SLD)

A year-long thematic unit for fifth-graders combines critical thinking and whole language frameworks to help students retain, understand, and make active use of knowledge within and across domains. Using systematic instruction in critical thinking, students explore the fundamental human concepts of race, sex, age, and power. David…

The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…

Investigated in this study were the influences of race, sex, and grade level on children's judgments of the acceptability of various intervention methods for dealing with two classroom problem behaviors: disturbing other students and destroying other students' property. In addition, the developmental applicability of the Children's Intervention…
