Presents two lesson plans for use when introducing computerized spreadsheet programs to high school students and discusses behavioral objectives, necessary equipment, teacher preparation, and learning activities for each lesson. Student handouts for use with the lessons are included. (MBR)

Computer algebra systems (such as MACSYMA and muMath) can carry out many of the operations of calculus, linear algebra, and differential equations. Use of them with sketching graphs of rational functions and with other topics is discussed. (MNS)

The focus is on the ability to create and relinquish hypotheses in problem solving. Given are activities that illustrate how to stress the importance of producing and evaluating new ideas. A hidden rule game, microcomputer software, and an attribute game are described. (MNS)

In one school, algorithmic development has been infused in the mathematics curriculum. An example of what occurs in mathematics classes since the teachers began using the computer is given, with two students' conjectures included as well as the algebraic justification. (MNS)

The project described in this article grew from the observation that many geometry students are unable to see anything in a diagram beyond a static presentation. A computerized microworld called "Motions" is described, with illustrations. (MNS)

A problem from a course called "Introduction to Gambling" is described. A flowchart and a computer program are included. (MNS)

We explore how 13 year-olds construct meanings around the notion of curvature in their classroom while working with software that combines symbolic notation to construct geometrical figures with dynamic manipulation of variable. The ideas of curve as intrinsic dynamic construction, and curve as object with properties related to its positioning on…

Mathematics is not only about learning problem-solving methods; it is also about gaining a deeper understanding of their purpose, advantages and disadvantages. Frequently, the same problem can be solved by applying several different methods. Mathematics education should also include clues to those best fitting to the person's aim. To achieve that…

Instructional resources that employ multiple representations have become commonplace in mathematics classrooms. This study will present computer software, LaborScale which was designed to improve seventh grade students' word problem-solving skills through computer-based multiple representations including graphic, symbolic, and audio…

Describes how students in a 10th-grade geometry class discovered relationships that led to the development of conjectures, theorems, and directions of proofs regarding the centroid of a triangle. (ASK)

Presents an activity on the sum of the measures of the interior angles of a five-pointed star by using The Geometer's Sketchpad. (ASK)

Differences in computer languages are noted. Symbol-based languages offer some distinct advantages over number-based languages, both in the form and the content of the student's interaction with the computer. Some of these advantages are explored and their applications to teaching mathematics described. (MNS)

Investigates using computer spreadsheets in math classes. Describes current spreadsheets on the market. Summarizes how the spreadsheets work and provides information to build a template to find function maximums and minimums. Lists step by step instructions. (MVL)

Examined is the effectiveness of a computer software package designed to be consistent with a fraction strip chart model. The materials are described; they were used with three fourth-grade classes, while two other classes acted as controls. (MNS)

Presents the geometric, software-ergonomic, and educative standards for interactive graphics systems envisioned for planimetric constructions and calculations in secondary mathematics instruction. Describes the geometric-didactic potentials of the MS DOS-Version 1.6 of CABRI-Gomtre which is an Intelligent Tutoring System with the possibilities for…
