Presented is a set of mathematics problems associated with the characteristics, production, and consumption of chicken eggs. Student assignment sheets are included. (CW)

Provided are three program listings which may be used to illustrate this fractal figure. Extensions of these algorithms and their use in the study of chaos and fractals are suggested. (CW)

Presented is an activity designed to develop a concrete linear model to assist students in estimating answers to percentage problems and developing an understanding of the concept of percentage. (CW)

Teaching methods which can be used to teach statistics at the primary, intermediate, and middle grades are described. Teaching data analysis and problem solving in this context are discussed. (CW)

Reports research findings regarding the learning and teaching of proportional reasoning. Presents four tasks devised to assess students' proportional reasoning and describes four solution strategies for solving these tasks based on the analysis of seventh and eighth graders' correct responses. (MDH)

This article explores the multiple representations (verbal, algebraic, graphical, and numerical) that can be used to study the golden ratio. Emphasis is placed on using technology (both calculators and computers) to investigate the algebraic, graphical, and numerical representations. (JAF)

Emphasizes a real-world-problem situation using sine law and cosine law. Angles of elevation from two tracking stations located in the plane of the equator determine height of a satellite. Calculators or computers can be used. (LDR)

Presents a lesson that connects basic transformational concepts with transformations on a Cartesian-coordinate system, culminating with the application of matrix operations to perform geometric transformations. Includes reproducible student worksheets and assessment activities. (MKR)

Discusses the mathematics and science underlying Eratosthenes' measurement of the circumference of Earth in about 200 B.C. and provides a lesson plan so that small groups of high school students can duplicate the measurements. Equipment needed and related Web sites are listed, and a model chart to record measurements is provided. (PEN)

Examined whether 11th-grade girls and boys enrolled in advanced mathematics courses nationwide were socialized in similar ways, using Campbell's differential socialization paradigm. Results uncovered a gender gap favoring boys. Self-imposed pressure and persistence had important direct effects on achievement. Self-concept had important direct…

Reports on a study of the effects of training in the use of social and cognitive strategies on the learning outcomes of students in secondary mathematics education. Results with 511 Dutch students show the positive effects of teaching cognitive and social strategies, with particular benefits for low-achieving students. (SLD)

Results of the Third International Mathematics and Science Study (TIMSS) illustrate the urgency of strengthening mathematics education. School leaders can determine whether more of Title I funds should be shifted to mathematics programs. Title I can be a key resource for raising expectations for students, professional development, and the use of…

Analyzes the construction of mathematical concepts and techniques developed by high school algebra students in computer-assisted instruction; examines learning styles of the most inventive students; and discusses the use of student-generated mathematical techniques in the development of new software intended to cultivate mathematical inventiveness…

Presents a mathematics activity to model the exponential growth of the common cold, AIDS, or any other communicable disease. Underscores the effect that a friend's or partner's previous behavior may have on a current relationship and on society at large. (ASK)

Investigates practices of high schools that encourage or discourage students' enrollment in advanced mathematics courses. Uses data from transcripts of more than 22,000 graduates of 305 public high schools. Important findings concern the effects of graduation requirements and course offerings on the courses taken by all students and by particular…
