Discussed are experiences with students having mathematics anxiety. Describes how to increase the students' confidence and a method of guided practice. (YP)

Discusses common error-detecting identification codes using linear algebra terminology to provide an interesting application of algebra. Presents examples from the International Standard Book Number, the Universal Product Code, bank identification numbers, and the ZIP code bar code. (YP)

Provides an activity for determining the relationship between the displacement of light rays passing through a plate of transparent material and the angle of refraction for the material. Describes related concepts and skills, prerequisites, objectives, rationale, content background, lesson outline, worksheet, evaluation, teacher notes, and…

Discusses solving inequality problems involving linear programing. Describes the usual and alternative approaches. Presents an intuitive approach for finding a feasible solution by maximizing the objective function. (YP)

Examines the relationship between visualization and the middle school mathematics curriculum. Gives an overview of where and how visualization interacts with the curriculum. Investigates the role of visualization in developing inductive/deductive and proportional reasoning. (YP)

Suggests activities involving the use of indices. Provides five activities with examples for routine practice, pattern recognition, prediction, conjecture, generalization, factorization, and limit concept. (YP)

Investigates English students' strategies for addition and subtraction problems. Suggests some teaching methods for the results. (YP)

Examples used to illustrate Simpson's paradox for secondary students include probabilities, university admissions, batting averages, student-faculty ratios, and average and expected class sizes. Each result is explained. (DC)

The origins of the emphasis on formal proof are discussed as well as more recent views. Factors in acceptance of a proof and the social process of acceptance by mathematicians are included. The impact of formal proof on the curriculum and implications for teaching are given. (DC)

Reports students were more successful in estimation for a problem in context than for the pure computation. Describes students' strategies to make estimates in context. Discusses how to teach estimation. (YP)

Discusses research on the tensions in becoming a better mathematics teacher, including perspectives on the nature of mathematics, conceptual and procedural knowledge, and managing competing responsibilities. Implications for teachers and teacher preparation include revision of undergraduate mathematics courses, collaboration among mathematics…

Discusses the use of mathematics notebooks to help students organize homework, projects, and notes. Contains the notebook assignment description given to students, notebook table of contents, and notebook grading sheet. (MKR)

Describes two thought experiments, involving visualizing the behavior of functions, that can be turned into computer experiments. (MKR)

Two scheduling problems, one involving setting up an examination schedule and the other describing traffic light problems, are modeled as colorings of graphs consisting of a set of vertices and edges. The chromatic number, the least number of colors necessary for coloring a graph, is employed in the solutions. (MDH)

Partnership for Access to Higher Mathematics uses fiber-optic technology in a partnership program among Southwest Texas State University, the San Marcos School District, the telephone company, and the community to significantly improve the mathematical skills of at-risk students. (MLF)
