"Lemonade" is one in a series of simulations designed to permit exploration of elementary concepts in economics. The nature of the simulation, problem-solving skills fostered, and suggestions for use of the program in the classroom are discussed. (Author/JN)

Examines the dimensions underlying the applied problem-solving process and describes the development of a problem-solving instrument based on factor-analysis results. Delineates initial reliability and validity estimates of the instrument. Discusses future research implications and provides a research instrument easily administered and scored.…

The author asserts that an important portion of an administrator's work is that of "problem finding." A case study and discussion of the relevant literature provide a definition of problem finding and its importance in understanding the work behavior of school administrators. (Author/MLF)

A technique for teaching the graphing of polar coordinate equations is presented. This approach involves the use of an auxiliary graph in rectangular coordinates and is thought to aid students in understanding of problem-solving situations such as in dealing with points of intersection and determination of limits of integration.

Many children do not appear to see any need to worry about the conventions for ordering operations or using brackets in algebra problems, due to the "intuitive" mode of approach they use in mathematics. The need to teach pupils the necessity of such conventions is discussed. (MP)

The needs for careful research and study in institutional evaluation are manifold, it is suggested, but it is important that educators monitor and guide the political and developmental aspects of this area. Guidelines for planning for institutional evaluation are provided. (Author/MLW)

Evaluated the possibility that three-year-olds solve small-number conservation problems by an empirical procedure whereby the sets are quantified each time presented. Children chose the more numerous of two arrays, one containing two elements and the other three elements. Results disconfirmed claims that three-year-olds can conserve small numbers.…

An approach to equation solving using calculators that promotes the trial-and-error method as a useful strategy when combined with calculators is presented. The approach is specifically geared towards the secondary schools as a way of moving to harder equations that the linear and quadratic ones traditionally used. (MP)

Some single species and two species interactions in population models are presented to show how credible examples can be used to teach an underlying, common mathematical structure within apparently different concepts. The models examined consist of differential equations, and focus on real-world issues. (MP)

Two exploratory studies of one aspect of the relation between problem solving in mathematics and the cognitive effects of games on mathematics learning are noted. Results indicated that problem solving and the playing of certain games involving mathematics are related. (MP)

Research was viewed as needed to establish a classification scheme for the major areas of difficulties individual students have in solving word problems. The results suggest that inability to read problems is a major obstacle for sixth graders, and mastery of components of problem solving ensures process mastery. (MP)

This investigation: (a) assesses developmental differences in children's estimation skills through normative data on performance on a variety of problems; (b) assesses validity of a proposed estimation model on the basis of children's performance; and (c) suggests modifications of the model as a guide to further research. (MP)

Argues for a decision-making-oriented science and technology curriculum for secondary school students which should: (1) expose students to open-ended problems within their natural setting; (2) provide students with real decision-making situations; and (3) involve students in scientific/technological social actions (in community institutions or…

To encourage students to become involved in the inventive and imaginative dimensions of biology, students are asked to invent: a useful product, way to use old newspapers, insect repellent, organism attracter, organelle separater, way to measure rate of hyphal growth, and method to measure strength of spider web. (DC)

Exploratory studies of the role of hemisphericity in creative functioning were made of graduate students. Results from instruments assessing hemisphericity, creative style or personality, and creative ability or level indicate that measures of creative style are positively related to the right hemisphere style of information processing.
