Discusses two problem-solving activities combining the introduction of resistance from physical science with mathematical functions. Provides questions and answers related to the activities. (YP)

Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)

Problem solving by example is an intermediate step toward mastering problem-solving heuristics. Discussed are problem-solving processes by using two problem examples. Emphasized are heuristics cataloging in a problem-solving log, and approaches to solutions, not the solutions themselves. (YP)

Describes the environments existing in Southwestern schools having a majority of Native American students. Concludes that the schools have a potential to promote Native American participation in science and mathematics, but they have high teacher turnover and limited amounts of professional contact and communication. (YP)

Investigates superintendents' needs in mathematics and science instruction. Used was a Likert-type questionnaire covering teacher quality, teacher supply, minority access, materials and equipment, and curriculum for non-academic students. A follow-up telephone survey examined the types of materials and equipment most needed. (YP)

Reports that those who were taught proportions exhibit more of a tendency to transfer than those who were not. Investigates the relationship of previous learning and problem-solving abilities to the learning of proportionality in facilitating transfer. Shows the magnitude of effects of task assignment on transfer. (YP)

Discusses the organization and retrieval of information. Describes the tip-of-the-tongue state during mathematics problem solving. Provides five rules for a deep level of processing of new concepts. (YP)

Reviews four software packages: "Scientific Reasoning Series: Batteries and Bulbs," dialogue-type software for physics; "More Teasers from Tobbs: Fractions and Decimals"; "Personal Consultant Plus," an expert system software package; and "How the West Was One + Three X Four," problem-solving software using arithmetic notation. (YP)

Describes several phenomena in which interesting properties of numbers are demonstrated. Includes discussions of amicable, perfect, and sociable numbers. Presents computer programs for conducting a number chain search. (RT)

Describes a study to evaluate the effect of the Energy Education Curriculum Program as perceived by elementary and secondary classroom teachers. Results indicate that energy education is taught in schools when materials and information are made available to the classroom teacher. (RT)

Presents a method for using matrix algebra and computers to encode and decode secret messages. Provides examples of coding procedures, a short review of matrix multiplication, and a BASIC program for use with secret messages containing up to 1000 numbers. (RT)

Discusses an activity for the use of tangrams in which students flip, rotate, slide, or patch the pieces in order to construct a particular shape. Examples include provisions for constructing two trapezoids; transforming a scalene triangular region into quadrilaterals of equal area; and transforming a cross into a picture frame. (RT)

Outlines procedures for helping students develop and clarify their understanding of science terms and concepts. Explains the semantic feature analysis strategy, concept ladder, concept-relationship procedure, semantic mapping, and use of the word card as ways to teach reading in science. (RT)

Provides a discussion and an example of a problem which occurs in mathematical contests or entrance examinations and deals with the question of the magnitude of exponentials. Includes additional illustrative examples. (RT)

Reviews evidence in support of the primacy of the personal relevance orientation in science education. Provides a quick review of four other orientations and their shortcomings for curriculum planning. Orientation reviews focus on: (1) the development of cognitive processes; (2) social adaptation and reconstruction; (3) academic rationalism; and…
