Convexity.
Peer reviewed Peer reviewed
Berger, Marcel – American Mathematical Monthly, 1990
Discussed are the idea, examples, problems, and applications of convexity. Topics include historical examples, definitions, the John-Loewner ellipsoid, convex functions, polytopes, the algebraic operation of duality and addition, and topology of convex bodies. (KR)

Polygonal Numbers and Recursion.
Peer reviewed Peer reviewed
Miller, William A. – Mathematics Teacher, 1990
Presented is a lesson in which the patterns that occur within and between sequences of polygonal numbers present an opportunity for students to analyze, represent, and generalize relationships. Materials, objectives, levels, and directions for this activity are discussed. Worksheets to accompany the activities are provided. (CW)

Has Progress in Mathematics Slowed Down?
Peer reviewed Peer reviewed
Halmos, Paul R. – American Mathematical Monthly, 1990
Reported is whether and how mathematics has changed during the 75 years of the Mathematical Association of America's (MAA) existence. The progress of mathematics is organized into 9 concepts, 2 explosions, and 11 developments. (KR)

A Review of Selected Microcomputer Software Packages with Lessons for Teaching Mathematics Grades 8-12. [Volume 1.] A Curriculum Development Project of the Project To Increase Mastery of Mathematics and Science (PIMMS).
Cetorelli, Nancy; And Others – 1987
The purpose of this project is to help teachers of mathematics use the computer to aid the teaching and learning of many mathematical concepts in a meaningful way. To this end, commercially available software packages are described which are versatile, cost effective, and easy to use. A review and several lessons, each including homework…

RATGRAPH: Computer Graphing of Rational Functions.
Peer reviewed Peer reviewed
Minch, Bradley A. – Journal of Computers in Mathematics and Science Teaching, 1987
Presents an easy-to-use Applesoft BASIC program that graphs rational functions and any asymptotes that the functions might have. Discusses the nature of rational functions, graphing them manually, employing a computer to graph rational functions, and describes how the program works. (TW)

Beyond the Evident Content Goals Part III. An Undercurrent-Enhanced Approach to Trigonometric Identities.
Peer reviewed Peer reviewed
Dugdale, Sharon – Journal of Mathematical Behavior, 1990
The third in a series of 3 articles, a study of 30 students was conducted to test the effect of restructuring a unit on trigonometric identities around microcomputer activities based on the themes of educational undercurrents identified in Part II. Experimental-group students scored significantly higher relating trigonometric functions to their…
