Presents six learning exercises that introduce students to the mathematics used to control and track spacecraft attitude. Describes the geocentric system used for Earthbound location and navigation, the celestial sphere, the spacecraft-based celestial system, time-dependent angles, observer-fixed coordinate axes, and spacecraft rotational axes.…

Demonstrates a laboratory to teach the concept of moment of inertia in which students are asked to identify four objects of equal mass sealed in unopenable containers by identifying the mass distribution of each object. Gives instructions to build an instrument to determine relative distribution of mass. (MDH)

Discusses the role of teacher questioning in the development of a child's concepts of and about mathematics. Proposes the development of mathematical concepts and procedures in problem-solving situations through questioning that engages student thinking and decision making. (MDH)

Discusses hypermedia; examines cognitive theories of learning and hypermedia; and describes hypermedia applications in science education, including physical delivery of information, curriculum design, and promotion of scientific inquiry. Research projects at Vanderbilt University dealing with aspects of science education, including elementary…

Reports a correlational study to determine whether teacher's mathematics anxiety might inhibit the introduction of more problem solving and abstraction in elementary schools to enable more ninth graders to enroll in algebra. Correlations on 19 variables for 116 teachers indicated that anxiety decreased with increased mathematics content studied…

Describes an eight-day graphing unit for grades four through six using data collected from a local cemetery. Provides the activities of each day and excerpts of discussions taking place during the lessons. Concludes that working with real data helps students construct meaningful graphs. (MDH)

Describes the design and use of SCORE (Sales and Customer Service Occupational Readiness Education), courseware developed by AT&T to provide midliterate adult customer service representatives with computer-assisted instruction. Topics addressed include job simulations; skills in reading, writing, math, problem solving, and critical thinking;…

Describes a study that examined problem-solving strategies selected by African-American preschool students with differing cognitive styles using LOGO computer software. Highlights include spatial development, minority performance and cross-cultural differences in cognitive style, and differences in field-dependent/field-independent children in…

Investigated gender-related differences in the process of solving routine word problems using a nine-step strategy in (n=153) sixth- and (n=149) eighth-grade students. Females were slightly better than males at following the prescribed problem-solving process. Includes test items. (39 references) (MKR)

Discussion of expert systems and how they can be used focuses on recent research and empirically validated interface features. Highlights include immediate feedback; text brevity; graphics; explanations and human information processing abilities; novice user learning styles; multioption displays; users' mental models; incidental learning; and…

Maintains that educational reform is related directly to issues of creativity and critical thinking. Contends that the creative dimension of thinking is fostered best by joining it with the critical dimension. Includes a figure and eight basic conditions implicit in creative, critical acts of the mind. (CFR)

The idea that studying part-whole number relationships can foster a better understanding of number concepts, addition, subtraction, fractions, decimals, ratios, and percentages depending on the age of the student is discussed. Activities that incorporate number relationships and representations are presented. (KR)

This article discusses the analysis of a decision-making process faced by contestants on the television game show "The Price is Right". The included analyses of the original and related problems concern pattern searching, inductive reasoning, quadratic functions, and graphing. Computer simulation programs in BASIC and tables of…

Discussed is the success of a small university in placing African Americans into medical school and pharmacy school. Described are precollege enrichment programs for mathematics and science that emphasize problem solving, homework, daily quizzes, development of vocabulary and reading skills, peer support groups, role models, and parental…

Described is the use of story telling as a context to introduce mathematical concepts by providing a model, offering problem-posing situations, stimulating investigation, and illustrating concepts. Examples of appropriate stories are given for the primary and low secondary levels. (MDH)
