Shows that the construction of mental representations that capture a situation based on the comprehension of a diagram are mediated by the possession of appropriate background knowledge. Indicates that background knowledge deficiencies may make it difficult for beginning students of a domain to construct suitable mental representations from…

The purpose of this paper is to show how data mining may offer promise as a strategy for discovering and building alternative representations for the data underlying asynchronous discussion forums. Presently, the instructor's view of the output of a threaded forum is limited to reviewing a transcript or print version of the written dialogue…

The present study extends the literature base that is answering the call to examine the validity of J. L. Holland's (1959, 1997) 6 types of themes (realistic [R], investigative [I], artistic [A], social [S], enterprising [E], and conventional [C]) in his typology when applied to populations that are culturally different from the populations with…

Whereas some research on immediate recall of verbal lists has suggested that it is limited by the number of chunks that can be recalled (e.g., N. Cowan, Z. Chen, & J. N. Rouder, 2004; E. Tulving & J. E. Patkau, 1962), other research has suggested that it is limited by the length of the material to be recalled (e.g., A. D. Baddeley, N. Thomson, &…

The authors examined the prioritization of abruptly appearing objects in real-world scenes by measuring the eyes' propensity to be directed to the new object. New objects were fixated more often than chance whether they appeared during fixations (transient onsets) or saccades (nontransient onsets). However, onsets that appeared during fixations…

Charlotte, the author's 11-year-old daughter, was born with Down syndrome, and is currently attending the local middle school. In terms of her disability Charlotte is developing very well and has a reading age of 9+, however her maths skills age is approximately 4 years. It is not necessarily the case that if a child has good language and literacy…

The notion of optimality is often invoked informally in the literature on metacognitive control. We provide a precise formulation of the optimization problem and show that optimal time allocation strategies depend critically on certain characteristics of the learning environment, such as the extent of time pressure, and the nature of the uptake…

Seriation refers to the process of ordering objects along single or multiple magnitude dimensions such as length, weight, and color. The ability to order objects in terms of some attribute is essential for the child's understanding of the properties of numbers. This study investigated the effect on seriation performance of increasing both the…

Human behavior shows a variety of serially ordered action sequences. This paper presents a theory of serial order which describes how sequences of actions might be learned and performed. In this theory, parallel interactions across time (coarticulation) and parallel interactions across space (dual-task interference) are viewed as two aspects of a…

This booklet describes basic counting principles and provides activities designed to develop basic skills in: (l) stable ordering; (2) one-to-one matching; (3) total number; (4) different objects; and (5) different order. These are extended to more advanced strategies aimed at building counting skills strong enough to provide a basis for adding,…

This study investigates (1) the relationship of two potentially valuable measures of sequential processing to each other and to a measure of digit span, and (2) the relationships among tests of sequential processing and other measures of cognitive functioning. Subjects were 188 first grade students who had been screened in kindergarten for risk of…

This study investigated the effects of the direction of print on learning-disabled students' and normal students' abilities to learn the sequence in which sentences are presented, to comprehend sentences, and to recognize relationships among sentences. Four groups of 12 learning-disabled pupils and four groups of 12 normal pupils between the ages…

Language as an identifiable cognitive behavior must be studied in relation to identity and memory, all of whose structures undergo progressive changes as the child develops. The organization of the development of the organism depends upon relatively ordered structures of growth, following foreseeable pathways or creodes. The processes occurring…

Forty-eight grade-three children and 48 grade-eight children were presented respectively with six- and eight-letter sequences for written free recall. The older children, as had adult subjects in previous studies, showed a greater tendency to recall serially with a four-letters-per-second presentation rate than with a half- or…
