Presents various shortcomings of applying a per-pupil cost structure for determining teaching cost. A proposed alternative approach determines the cost of providing teaching capacity separately. It is applied to a number of situations and the comparative results are presented. (JMF)

The performance of 76 students (ages 10 to 15) with learning disabilities on four tasks of arithmetic computation within each of the four basic operations was examined. Tasks varied in difficulty level and number of strokes needed to complete all items. Intercorrelations between task sets and operations were examined as was the use of…

Presents a computational framework for modeling cognitive development that provides a language paradigm with which to compare and contrast different facets of children's knowledge. Describes the generative connectionist algorithm "cascade-correlation," the successful use of the algorithm to model cognitive development in various…

Examined children's mathematical competencies between ages 7 and 9. Found no differences in developmental rate between children with math difficulties only (MD), math and reading difficulties (MD-RD), reading difficulties only (RD), and normal math/reading achievement (NA). Found that at end of Grade 3, MD group performed better than MD-RD group…

Discusses the effects technology may have on human intelligence. Topics include the use of computational devices, including calculators, in schools; the changes word processing has brought about in writing; the use of television; and the effects of weapons on children. (LRW)

Describes a professional development project to increase teachers' understanding of proportional reasoning, the thinking patterns associated with proportional reasoning, and the applications of proportional reasoning across the middle-grades curriculum. (YDS)

Described is the Delaware Elementary Mathematics League; a state mathematics competition for grades 4-6. Included are specific sample test items and a discussion of how they can nurture the development of problem-solving skills. Sample tests are also discussed. (CW)

Described is a study in which three instructional approaches were applied in second grade classes. Discussed are proportional materials, nonproportional materials, nonproportional materials with pictorial models. Findings, results, and recommendations are presented. (CW)

One teacher's approach to the development of number sense while using calculators is outlined. The relationship between number sense and calculation is discussed. Teaching strategies and two worksheets used in this approach are presented. (CW)

Presented are three physics problems from the New Zealand Entrance Scholarship examinations which are generally attempted by more able students. Problem situations, illustrations, and solutions are detailed. (CW)

Presented are ideas for the utilization of Microsoft Works in the secondary mathematics classroom. The spreadsheet and graphing capabilities of this software package are demonstrated for several topics including the concept of slope for first year algebra, and creating and interpreting graphs for a general mathematics class. (Author/CW)

Explores developmental (age) differences in meaning that children at four grade levels assign to count and relational quantifiers. Results indicated 92 percent of the children demonstrated understanding of all count quantifiers. For relational quantifiers, mean numerical values assigned to four terms followed expected patterns; understanding of…

Reports examples of the behaviors, including kinetic and vocal, used to facilitate problem-solving based on observations of four seventh-grade students. Discusses the use of the behaviors in problem-solving teaching. (YP)

Describes four activities designed to discover numerical patterns using a calculator or paper and pencil. Provides tables and figures for the activities. (YP)

Investigates children's behaviors and conceptual achievements in the transition from informal calculation strategies to a written division algorithm. Describes five different strategies observed in the solution of division problems. Discusses the implications of the children's behavior. (YP)
