As more archival metadata and archival records become available online, providing effective interfaces to those materials is increasingly important to give users access. This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures,…

Successful treatment of many childhood diseases once considered terminal has resulted in the emergence of long-term effects of the disease or consequences of treatment that were previously unrecognized. Many of these long-term effects involve the central nervous system (CNS) and are developmental in the way that they emerge over time. Because we…

The Landau-Kleffner syndrome (LKS) and electrical status epilepticus in slow wave sleep (ESES) are rare childhood-onset epileptic encephalopathies in which loss of language skills occurs in the context of an epileptiform EEG activated in sleep. Although in LKS the loss of function is limited to language, in ESES there is a wider spectrum of…

As part of standards-based educational reform efforts, more than 40 states will soon require students to achieve passing scores on standardized exams in order to obtain a high school diploma. Currently, many states are struggling with the design of their examination systems, debating such questions as which subjects should be tested, what should…

In times of dramatic social change, new career options emerge and old options may become obsolete. We investigated predictors of change in general career aspirations and of plans to attend a university of East German adolescents from 1989 (before German unification) to 1991 and 1995, respectively, after German unification. Higher pre-unification…

This article presents a framework for the cognitive diagnosis of learners' errors in an interactive learning activity occurring in an intelligent learning environment. The proposed framework supports the implementation of an authoring tool. This tool helps instructional designers to specify the features of a component for cognitive diagnosis. Two…

This paper reports two studies that investigate differences in comprehension monitoring skills between good and poor comprehenders. Two groups of 9- to 10-year-olds, who were matched for reading vocabulary and word recognition skills but who differed in comprehension skill, were selected. In the first study, in which the children were required to…

We use a genetically sensitive design to examine the relationship between language and nonverbal ability at 4 and a half and reading skills at 7 years of age in a sample of more than 1,000 children participating in the Twins Early Development Study. We find that nonphonological as well as phonological measures of early language make significant…

The authors tested a model of the relations among adolescents' perceptions of parents', teachers', and classmates' support for, valuing of, and beliefs about their competence in math/science; adolescents' own academic self-perceptions concerning math/science; and their academic performance. The sample included 378 middle school students; 65% were…

In this study, the author examined whether family system functioning was associated with resilience in children exposed to negative environmental stress. In a sample of 55 low-income, urban families, greater differentiation of self among mothers predicted child competence--that is, better verbal and math achievement scores and lower…

The number skills of groups of 7- to 9-year-old children with specific language impairment (SLI) attending mainstream or special schools were compared with an age and nonverbal reasoning matched group (age control [AC]) and with a younger group matched on oral language comprehension. The SLI groups performed below the AC group on every skill. They…

This article describes a longitudinal analysis of a nationally representative cohort of over 80,000 pupils in England who completed both national end of Key Stage 2 (KS2) tests and the Cognitive Abilities Test (CAT) at age 11 in 1997, national end of Key Stage 3 (KS3) tests at age 14 in summer 2000 and General Certificate of Secondary Education…

The teaching of grammar is discussed from an instrumental point of view: what beneficial effects does such teaching have for students' language abilities (especially writing)? Two ways of approaching grammar teaching are confronted with each other: the learning of explicit rules and meta-linguistic knowledge about language on one hand and learning…

International schools are increasingly identifying Functionally Multi-Lingual children in their student populations. These students, bilingual or multilingual at surface levels of conversation, have not established academic competence in any single language. In many cases, the teacher may assume that another, more robust language exists, when in…

To explore the relationship between youth and adult leadership--or the relationship between the youth leadership literature and the adult leadership literature--it is important to examine where and how youth appear in the discussions on leadership. Based on a comparison of the literature focused on adult leadership development compared to the…
