Reports on a small-scale study of 13 dyads working at number tasks that found "sidework," a modified form of associative interaction, gave rise to more high order talk and to more posttest learning than did collaboration. Suggests sidework may have greater potential to enhance students' learning than the collaborative mode. (TJQ)

Describes a paradigm for generating a variety of problem situations in middle school mathematics, ranging from combining a single mathematical concept or process with a single context, to combining multiple concepts or processes with multiple contexts. Offers several illustrative examples. (SR)

A more fragmented approach to assessment of global ability concepts than is generally advocated is suggested, based on the assumption that decomposing a complex ability into cognitive components and tracking performance across multiple measures will yield valid and instructionally useful information. Specifications are suggested for designing…

Practical Geriatrics, 10 continuing medical education programs, combine lecture, role models on videotape, problem-based learning, and commitment for change. Tests with four groups of community practitioners (n=83) demonstrated the program's effectiveness in inducing change and sparking participant enthusiasm. (SK)

Presents case study exemplifying use of curriculum-based measurement (CBM) in educational decision making. CBM is portrayed as more than just set of brief fluency tests with strong conceptual ties to three related assessment models (behavioral, ecological, and problem-solving assessment). Delineates key elements of each model. Case study shows how…

Polynomial algorithms are presented that are used to solve selected problems in test theory, and computational results from sample problems with several hundred decision variables are provided that demonstrate the benefits of these algorithms. The algorithms are based on optimization theory in networks (graphs). (SLD)

A six-step method is presented for using problem-solving activities to promote language acquisition in hearing-impaired students. The method emphasizes the communicative uses of language rather than the structure of language. A list of sample problem-solving activities is included. (JDD)

The drawn ideas of inventors Edison and Bell are analyzed in a systematic way to help understand the inventive process and how inventors think. By storing sketches on a computer the researchers have been able to recreate the probable lines of reasoning used by the inventors. (KR)

Describes the "Two-Eight" instructional model for students who have arithmetic computational skills but lack the ability to select appropriate strategies to solve problems. Offers examples showing the replacement of the actual values used in a word problem with the simple numeric values of 2 and 8 to create a parallel, solvable problem. (DMM)

A model for solving very large item selection problems is presented. The model builds on binary programming applied to test construction. A heuristic for selecting items that satisfy the constraints in the model is also presented, and various problems are solved using the model and heuristic. (SLD)

Proposes that teaching methods be changed to move away from a positivist model toward an ecological model. Discusses three assumptions for future practice involving holism in environmental studies; the role of values in environmental studies; and the process of learning. (Contains 26 references.) (MDH)

Discusses suggestions for the learning and teaching of mathematics based on a study examining the mathematics practices of carpet layers. Suggestions are made from the areas of (1) the school mathematics curriculum; (2) the methods used to teach school mathematics; and (3) research in mathematics education. (MDH)

Presents a lesson that introduces students to polarized light using a problem-solving approach. After illustrating the concept using a slinky and poster board with a vertical slot, students solve the problem of creating a polarized light show using Polya's problem-solving methods. (MDH)

Discusses a strategy to present girls with models of hardy female personalities through examples of young problem solvers found in children's literature to nurture and build the strength in female students to tackle problem-solving situations. Contains 17 references. (ASK)

Evaluated 9-, 14-, and 19-month olds' strategies as they grasped and used spoons presented with the handle alternately oriented to left or right. Found that younger children reached with their preferred hand, disregarding the item's orientation. Older children anticipated the problem, alternated the hand used, and achieved an efficient radial grip…
