Asserts that infringements on the freedom to research and teach detracts from effective teaching and unbiased research. Suggests that some sociologists permit infringements out of confusion over possible outcomes and fear of being punished for noncompliance. (CFR)

Examines the importance of learning environments as sites for change in science education, describing work with elementary teachers in which researchers are designing learning environments featuring guided inquiry. After explaining how to plan and enact guided inquiry instruction in science, the paper reflects on experiences implementing it in…

Two studies investigated ways in which computer and video technology can support expert human coaches in order to reduce instructor time and increase learner-centered environments; the goal was to train undergraduate students to facilitate others' interpersonal problem solving. Results indicate that the technology-supported methods can decrease…

Contends that the nature of U.S. urban life has created profound challenges for urban schools. Asserts that music educators must examine innovative trends in policy, programming, and curricula to determine how music can contribute to better schools and a better quality of life in urban areas. (CFR)

This paper presents the educational method of role taking as a means of teaching communicative competence in a second language. The method calls for encouragement of student "creative work" and "coping with" the learning material. A sample lesson used in South Africa with students (ages 11-13) learning English as a Second…

Abstract ideas in linear algebra are illustrated at different levels of difficulty through the investigation of the solution to a well-known puzzle. Matrices are used to model the puzzle and the concepts of rank, underdetermined systems, and consistency are employed in the solution to the problem. (MDH)

Presents an approach to the concept of absolute value that alleviates students' problems with the traditional definition and the use of logical connectives in solving related problems. Uses a model that maps numbers from a horizontal number line to a vertical ray originating from the origin. Provides examples solving absolute value equations and…

Discusses the equation and proportion methods for teaching how to solve percent problems. Supplements the teaching of each method by introducing a representational model that enhances understanding when solving percent problems. (MDH)

Explores alternative strategies to solve algebraic equations that do not lend themselves to traditional methods. Examines one nontraditional equation by a graphical approach using a graphing utility and by a numerical approach using spreadsheets. Discusses new basic skills for algebra utilizing technology. Provides a computer program to solve…

Presented is the idea that art can be used to present early concepts of geometry, including the notion of the infinite. Discussed is the symbiosis that exists between the artistic and mathematical views of points, lines, and planes. Geometric models in art and using art in the classroom are discussed. (KR)

Presented is a way to provide students with a review and an appreciation of the versatility of pointers in data structures by improvising with binary trees. Examples are described using the Pascal programing language. (KR)

Discussed are the possible uses of spreadsheets in the undergraduate curriculum in chemical engineering classes. The advantages and flexibility of spreadsheets, spreadsheet instruction, graphing capabilities, assignment examples, and conclusions are described. (KR)

This article reviews studies that have attempted to increase three types of social skills in blind and visually impaired individuals: assertiveness training, interactional skills, and skills in physical expression. Most of the studies reported increased social skills following intervention; however, many did not report empirical evidence of…

Discusses the use of computer-assisted programs that allow chemical engineering students to study textbook thermodynamics problems from different perspectives, including the classical graphical method, while utilizing more than one property correlation and/or operation model so that comparisons can be made and sensitivities determined more…

Described is an activity that categorizes a two-digit number as "sneaky" if the continued process of taking the difference of the squares of its digits leads to a difference of zero. Other categorizations are determined by whether the difference process ends in a one-digit number or continues in a loop of numbers. (MDH)
