Mobile devices have been increasingly utilized in informal learning because of their high degree of portability; mobile guide systems (or electronic guidebooks) have also been adopted in museum learning, including those that combine learning strategies and the general audio-visual guide systems. To gain a deeper understanding of the features and…

Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue…

Proposes a criterion for selecting a sequence of objectives from a learning hierarchy and describes a sequence generating algorithm which is designed to generate a minimal memory load sequence from a learning tree. Its effectiveness in generating low memory load sequences from hierarchies that are not trees is also discussed. (RP)

Provided is an analysis of Turtle Geometry using van Hiele levels of development and understanding. The author also relates a language use framework, suggested by the work of Fry (1982), to the language activities of Turtle Geometry. Research supporting the analysis is discussed. (RH)

This study investigated the effects of sequence and synthesis prescriptions from the Elaboration Theory by teaching the parts of a microcomputer system based on a parts-conceptual structure. A 2x3 factorial design was used which incorporated two sequences, general-to-detailed and detailed-to-general, and three levels of synthesizer, i.e., no…

Nine students (ages 7 to 11) with math disabilities were effectively taught using an instructional sequence that moved from the concrete to the semiconcrete to the abstract. Subjects needed between three and seven lessons using manipulative devices and pictures before being able to do abstract-level problems. (Author/DB)

The relationship between language and symbolic play was studied in a sample of children identified as referential in style (multiple noun utterances exceeded pronoun or no-noun utterances), as compared with a sample identified as expressive in style (pronoun utterances or no-noun utterances exceeded multiple noun utterances). Children were…

Describes probabilistic document retrieval systems as a sequential learning process, in which the system learns the parameters of probability distributions describing the frequencies of feature occurrences in relevant and nonrelevant documents. Several techniques for estimating the parameters of distributions are described and the results of tests…

Two studies, one within subjects and the other across subjects, evaluated the efficacy of teaching sounds in developmental sequence to nine young children (ages three to five). Treatment of later-acquired phonemes led to systemwide changes in untreated sound classes, whereas treatment of early-acquired phonemes did not. Findings suggest…

Nineteen children with developmental delays in the first stage of language learning conversed with their parents in a laboratory setting. Adult utterances were coded for topic, question type, and nonquestions. Child utterances were coded for topic. Child topic continuations were more likely to follow adult continuing questions than any other type…

Measures children's attention to television programs varying in pace and continuity and assesses recall of the temporal sequence of program events. Attention and comprehension covaried more in animated than in live shows. Age, continuity, and pace effects on recall were not fully accounted for by their effects on attention. (Author/AS)

Nine children participated in one of three groups: children diagnosed as both sensory and language impaired, children diagnosed as language impaired, and normally developing children matched for language level. Sensory integration activities prior to language intervention resulted in significant changes on the Battelle Developmental Inventory for…

Analysis of Kaufman Assessment Battery for Children (K-ABC) Sequential and Simultaneous Processing scores of 94 children (ages 6-12) with learning disabilities produced factor patterns generally supportive of the traditional K-ABC Mental Processing structure with the exception of Spatial Memory. The sample exhibited relative processing strengths…

This study investigated the effects of different structures of a synthesizer and formats of the generality component on the application and remember levels of learning. Seventy-three undergraduates participated. Four treatment groups were formed by combining two types of structure (complete versus partial) with two types of format in generality…

Using the Component Display Theory as an analyzing tool, this study compared the effects of expository and discovery methods of instruction on two learning outcomes, application and transfer. One hundred ninth grade students in each of four earth science classes were randomly assigned to five groups--four experimental groups designed to test four…
