The relationship between the development of object permanence and early words was studied in three young boys, two totally blind from birth and one severely visually impaired. Subjects acquired early words within the age range for sighted children but their word usage was different. The two blind children were delayed in their development of…

Five young adult females with mild mental retardation were given match-to-sample training to develop four classes of equivalent stimuli. All subjects demonstrated development of all possible equivalence classes involving these stimuli. For four of five subjects, the classes that included auditory stimuli developed more rapidly than those that did…

This article outlines a series of skills needed by young children with disabilities to be prepared to effectively use computers later in life, and provides exercises to promote these skills. Skills emphasized include: decision-making, cause-and-effect thinking, muscle control, and directional and sequencing skills. (PB)

Concepts of fractions from an adult perspective as well as from a child's perspective are examined. Types of students' schemes for some terms related to fractions are reported. (YP)

Investigates, both quantitatively and qualitatively, the relative efficacy of textual and instructional manipulations on concept acquisition. Finds no significant differences among four treatment groups on concept comprehension and learning. Examines text-processing strategies qualitatively. Presents an instructional model of the construct of…

Investigates processes involved in helping young children acquire musical concepts. Concludes that, even though children's involvement with musical skills and activities aids concept development, the enjoyment and experience of music should be predominant. (NH)

Examines two designing traditions and their influence on architectural design education. Points out that the emphasis upon either idea or technique is often uneven in proportion even though design is, in fact, an interaction of the two. Suggests that success of a course depends upon its methodological focus as well as its content. (KO)

It is argued that number sense develops through meaningful, purposeful activities involving calculating, measuring, and estimating. Understandings that must be developed with each are discussed. More emphasis needs to be placed on thinking about the various procedures that can be used to solve problems and on interpreting the answers. (MNS)

Suggestions for incorporating number sense into lesson warm-ups, lesson development, and practice exercises are provided. Ideas for developing a positive climate for thinking numerically are given. Then when, where, and how to develop number sense are discussed. (MNS)

Presents a dialog in five articles that address the issue of whether distance education is a discipline in its own right, primarily based on a 1986 article by Holmberg. Topics discussed include adult education; adult learning; conceptual models; and the roles of theory and research. (LRW)

The use of developmental algorithms to develop skills is described. Children make the transition from using concrete materials to using a standard algorithm. (MNS)

Investigates the development of understanding of quantity in 36 children with Down's Syndrome. Findings confirmed similarities in sequence of development between Down's Syndrome children and nonretarded children. Down's children who received training recognized conservation of continuous and discontinuous quantity. (RJC)

Autistic children were tested on three tasks that were within the capability of three-four-year-old normal children and that involved the abilities to understand a mistaken belief, infer contents of a container from looking or not looking inside, and adjust answers to provide new information. (PCB)

Investigates the nature of college student difficulties with negative values of velocity by using interviews. Discusses graphical representation of negative values of velocity and interpretations of graphs involving negative values of force. Suggests some instructional implications from the discussion. (YP)

Investigates the effect of modeling analogy on learning of the concepts of electricity in grade 6, 8, and 10. Describes 2 analogies (train analogy and thermal analogy) with diagrams and examples. Discusses the accessibility, transferability, and difficulty of each analogy. Reports treatment effect and some further implications. (YP)
