Suggested is the presentation of problems for which student teams are to write computer programs which will reveal the results of guesses at the answer by users of the program. Illustrative problems and programs are included. (MNS)

Four types of computational estimation were explored in relation to other mathematical skills and sex differences with 309 eighth graders. Open-ended estimation was the most difficult, followed by estimation relative to a reference number and estimation within an order of magnitude. (MNS)

Three innovative features of the new Caribbean mathematics examinations are discussed: increased information on candidates' performance, breadth of consultation and concern with social needs in the development of the syllabus, and conception and implementation of the syllabus as a curriculum. Appended are examples from the syllabus and…

Included in this section are brief articles on an algebraic puzzler, periodic decimal fractions with computers, and the arrow method of teaching logarithms. (MNS)

Answers and justifications for an interesting problem on the Advanced Placement Calculus AB Examination are discussed. The problem provides diverse ways in which students can gain appreciation and understanding for the subject. (MNS)

Reviews research which indicates that students performed better on problems when extraneous information was absent than when extraneous information was present. However, recommends that teachers embed word problems with realistic contexts, that is, contexts that contain extraneous bits of information to help students transfer their problem-solving…

Describes a system of computer assisted instruction geared primarily toward high school and university students involved in numerical analysis and optimization. Also describes (in detail) one of its modules to illustrate the general philosophy of the system. This module focuses on the simplex method. (JN)

A first computer lesson in algebra is described, with illustrations of programing by students. Standard algebraic notation with BASIC are discussed, and further activities described. The purpose is to use the computer so that it develops a rational understanding of the mathematical concepts involved. (MNS)

Lists and describes a program (Microsoft Basic) which: computes the value of a numberic function of two variables (x/y); uses x/y values to determine a spot on the screen; uses the function value to designate a color; and displays the color at the proper spots on the screen. (JN)

An application of transformation geometry to special relativity is described. No knowledge of physics is required, but the application uses transformation ideas in a nontrivial way. A comparison is given of reflections in the Euclidean and Minkowski (non-Euclidean) planes. (MNS)

Describes eight increasingly sophisticated and efficient sorting algorithms including linear insertion, binary insertion, shellsort, bubble exchange, shakersort, quick sort, straight selection, and tree selection. Provides challenges for the reader and the student to program these efficiently. (JM)

The authors contend their study and criticism of the Benbow and Stanley results were valid. Benbow and Stanley's clarification that their conclusions pertain only to intellectually talented students and competency in mathematical reasoning ability resolves this disagreement. (DWH)

Reviews four commercially produced software packages for high school mathematics. Topic areas include: equations (tutorial); algebra (tutorial, drill and practice); general mathematics (tutorial, drill and practice); and graphing of algebraic equations (arcade games). Program name, hardware needed, format, current price, and source are provided.…

A New York City project to help high school students from minority groups prepare for mathematics-based careers is described. Bridge Projects, field trips and seminars, a summer institute, and other interventions are discussed. (MNS)

Results from a large-scale study of sixth-form and college students' understanding of elementary calculus and mathematical ideas underlying calculus are presented. Difficulties with speed, tables, linear graphs, curves and differences, the tangent as the limit, and the average rate of change are each discussed. (MNS)
