This paper advocates the use of symbolic computation packages as another aid in teaching geometry. The need for such packages and their use in computerized proofs are demonstrated by a problem in high school planar geometry. (LZ)

Two technology guidelines are contributed by Robin Rider of East Carolina University based on the TI-Interactive software she had introduced. The two guidelines to use for this software consist firstly of data gathering with a Calculator-Based Laboratory (CBL) and Calculator-Based Ranger (CBR) without a graphing calculator, and secondly the…

Archimedes' method for estimating the value of pi is developed and compared with the Gregory-Machin infinite series method. Programs for the TI-81 calculator for finding the upper and lower bounds using the classical method and estimating pi using infinite series are provided.(Author/MKR)

Presents a problem and a line of reasoning inspired by working in dynamic geometry environments and allowing students to make a geometric construction on the computer and then manipulate the construction by dragging points, lines, and segments. (MKR)

Discusses several dynamic geometry constructions with rectangles. Advocates use of software like Geometer's Sketchpad and Cabri Geometry for fostering fresh insight into traditional geometric theorems. Illustrates problem-solving methods not possible with pencil and paper. (MTE)

Presents an application of the software tool DERIVE in the exploration and visualization of a relationship between logarithmic and exponential functions. (Author/MKR)

The question "What shape will have the largest area for a given perimeter?" identifies an important relationship between area and perimeter that has long been intuitively realized in many cultures. Historically, numerous cultures have made use of this relationship between area and perimeter when struggling to build dwellings with shapes…

Discusses the use of software created for practical, real-world applications to connect mathematics to other subjects and to the world outside the classroom. Software presented includes Design Your Own Home, Bridgebuilder, Physics Explorer, Aldus Superpaint, and Sprout. (MKR)

Provides an overview of a Vygotskian perspective for learning from hypermedia. Utilizes a Microsoft Dinosaurs teaching-learning episode to pose questions concerning the use of hypermedia for learning of mathematics and science. (Author/MKR)

Simple graphing activity helps primary students make the jump from counting concrete objects to understanding abstract symbols. As part of the activity, students vote for their favorite season, then stand up and become a graph of the data they collect. The activity requires the Graph Club Classroom Kit software program. (SM)

Demonstrates and compares three commercially available statistical software packages, Statistics Workshop, Data Insights, and Data Desk, using a five-component investigation model to analyze a problem about hat sizes. (MKR)

Suggestions are made for overcoming the problem posed by available mathematics computer software, which is primarily drill and practice and intended for use by one student at a time. Three commercial software programs are reviewed. (JD)

Explores families of parabolas that result from the graphs of quadratic functions. Computer software allows students to quickly depict a series of graphs and make conjectures about emerging patterns. Discusses cases in different parameters in the quadratic are varied to produce different effects in which the parabolas. (MDH)

Argues that students should have dynamic perceptual experience with the concepts central to circular functions. Includes a computer program, designed for Apple II, to provide such experience. (PK)

Use of computers in problem solving is highlighted. Several software programs are discussed and specific questions and activities are suggested. (PK)
