Uses rectangular models for illustrating products of numbers to solve mixture word problems. (MKR)

The common goal of the empirical studies discussed in this analysis was to assist children in developing a meaningful understanding of the rational number construct, founded on durable fraction concepts. Some research has focused on partitioning; some on ratio and proportion. Contains 59 references. (Author/MKR)

Four experiments investigated conceptual categorization in 7- to 11-month-old infants. Data revealed global differentiation of animals and vehicles, with lack of differentiation of basic level categories within the animal domain, in contrast to data from other studies designed to assess perceptual categorization. Results suggest that infants may…

Proposes a model of mathematics conceptual development consisting of two phases: abstraction and generalization. Illustrates model by references to the development of multiplication and angle concepts. (19 references) (MKR)

Within a small bounded space, the location of a hidden object can be coded in terms of distance information, general area of hiding, or the boundary of the space. The use of these three coding strategies by infants was examined using a visual search task. Results indicated boundary information and the nature of the change influenced coding of…

Proposes a theory of thinking based on a concept of dispositions that emphasizes individuals' inclinations, sensitivity, and abilities. Argues that seven dispositions are collectively sufficient and individually necessary to characterize thinking. (BC)

The study, with 57 children (ages 3-6) enrolled in 3 Head Start classes, demonstrated that short-term, large-group basic concept instruction combining direct instruction with interactive and incidental teaching techniques resulted in significantly improved scores on the Boehm Test of Basic Concepts-Revised. (Author/DB)

Poses solutions for our failure to show students how well mathematics interlocks with the physical structures of the Universe. Some examples are provided to illustrate the natural integration of mathematics and science. (ZWH)

An edited transcript of the recorded discussion among panel members at a symposium at the 1993 meeting of the American Educational Research Association pertaining to changes in standards across time and jurisdiction is presented. Participants' comments reflect concern about the validity and reliability of standards. (SLD)

Experiments with 251 male and 280 female college students demonstrated that subjects' representations of the water levels in a tilted container could be influenced by problem presentation. Subjects who did not appear to know that water remains horizontal were attempting to solve an object-relative, rather than environment-relative, problem. (SLD)

Three experiments examined the modes of processing that children and adults use in learning family-resemblance categories. Children and adults exhibited primarily analytic, rather than holistic, modes of learning. (PCB)

Comments on the research by Anglin reported in this monograph by considering two points. First, discusses possible problems in defining what a word is. Second, examines some problems with the methodology in vocabulary development research that involves testing individuals' knowledge of words by sampling words from dictionaries. (BC)

Describes a project which increased motivation for reading by involving students in real-world problems using the Concept-Oriented Reading Instruction approach. (SR)

Proposes a three-phased model of psychotherapy that entails progressive improvement of subjectively experienced well-being, reduction in symptomatology, and enhancement of functioning. A study suggests that improvement in well-being precedes and is probabilistically necessary for reduction in symptomatic distress and that symptomatic improvement…

Introduces a new way of looking at concepts called Hazyspace that focuses on the messiness of real life and the indeterminancy of concepts as key features in understanding the conceptual domain of human beings. Although Hazyspace has general applicability to education, this discussion focuses on use of the term to describe how new users…
