Previous research has demonstrated conflicting findings concerning orthographic access in older age. The current study examines whether older adults rely more heavily on stored knowledge while spelling, through testing of word concreteness. Forty-one younger (age 20-29), 41 middle age (age 45-55), and 40 healthy older adults (age 70-80) spelled 60…

This study explores whether and to what extent the background information supplied by 10,155 immigrants who took an official language test in Norwegian affected their chances of passing one, two, or all three parts of the test. The background information included in the analysis was prior education, region (location of their home country),…

Effective communication requires knowing the "right" amount of information to provide; what is necessary for a naïve learner to arrive at a target hypothesis may be superfluous and inefficient for a knowledgeable learner. The current study examines 4- to 7-year-olds' developing sensitivity to overinformative communication and their…

Children recognize that people who know more are better informants than those who know less. How does an individual's prior knowledge affect children's decisions about whom to inform? In 3 experiments, 3- to 6-year-old children were invited to share a novel piece of information with 1 of 2 potential recipients who differed in their recent history…

When teachers or instructors create computer-based learning environments, they often solely consider technical aspects of interactivity. As a consequence, learners' main role is to respond to requests of the learning environment (e.g. by answering multiple-choice questions). This aspect of interactivity is, however, not sufficient to understand…

The contributions of domain-general abilities and domain-specific knowledge to subsequent mathematics achievement were longitudinally assessed (n = 167) through 8th grade. First grade intelligence and working memory and prior grade reading achievement indexed domain-general effects, and domain-specific effects were indexed by prior grade…

High dropout rates are still a problem with online training. It is strongly suggested that learner characteristics influence the decision to persist in an online course or to drop out. The study explored the differences in domain-specific prior knowledge, motivation, computer attitude, computer anxiety, and learning skills between dropouts and…

This paper surveys the consequences of pupils' participation in the extra-curricular environmental education (EE) programme Club P.A.N. (Peoples, Animals and Nature) by monitoring changes in their respective knowledge as well as in their environmental attitudes. The programme was conducted in Côte d'Ivoire in West Africa with the help of the local…

In the context of "academic momentum," a longitudinal study of university students (N = 904) showed high school achievement and ongoing university achievement predicted subsequent achievement through university. However, the impact of high school achievement diminished, while additive effects of ongoing university achievement continued.…

It is argued that multimedia technology affords an opportunity to better visualise complex relationships often seen in chemistry. This paper describes the influence of chemistry simulation design facets on user progress through a simulation. Three versions of an acid-base titration simulation were randomly allocated to 36 volunteers to examine…

In this review of literature we examine empirical research of individual differences in younger readers' knowledge and use of expository text structures. The goal of this review is to explore the influence of reader and text characteristics in order to better understand the instructional needs of elementary school readers. First we review research…

In the field of children's knowledge of the earth, much debate has concerned the question of whether children's naive knowledge--that is, their knowledge before they acquire the standard scientific theory--is coherent (i.e., theory-like) or fragmented. We conducted two studies with large samples (N = 328 and N = 381) using a new paper-and-pencil…

This study evaluated the influence of general and mathematics-specific classroom instructional quality on the mathematical development of a sample of Head Start preschool children. It also examined whether children's age, pre-test mathematical knowledge, and English language learner status influenced the quality of their curricular…

Prior computer expertise represents one of the most important predictors of performance when interacting with ICT (Information and Communication Technologies) and acquiring computer skills. Due to demographic changes, the older adult will become increasingly important as a potential user. However, there is a lack of instruments for the assessment…

Three experiments examined how 4- to 10-year-olds' domain knowledge and observation of exemplars interact during concept acquisition and how exposure to novel exemplars causes knowledge revision. In all experiments, prior knowledge and exemplar observation independently influenced children's categorization judgments. Use of prior knowledge was…
