This paper reports on a case-study design experiment in the domain of fraction as number-measure. We designed and implemented a set of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. Two groups of 12-year-old students worked collaboratively using paper and pencil as well as a specially…

This research aims to explore the role of physical representations in young children's numerical learning then identify the benefits of using a graphical interface in order to understand the potential for developing interactive technologies in this domain. Three studies are reported that examined the effect of using physical representations…

Presents the listing (and documentation) for an arithmetic drill program with color graphics and sound. The program offers simple arithmetic problems illustrated by colorful dinosaurs. A buzzer sounds if an answer is incorrect while a short piece of dinosaur music is heard if an answer is correct. (JN)

Purpose: The purpose of this scientific monograph is to show new and creative approaches to different school subjects in primary and secondary level. Methodology: Interdisciplinary and international comparative approaches were used. Now according to the 7th Framework Program, the preferred form of Science Education (www.scientix.eu) is preferred…

Presents various exercises and programs to demonstrate how low-resolution graphics (for Apple microcomputers) can be utilized in the mathematics classroom. (JN)

Discusses high resolution (hi-res) graphics programing on the Apple microcomputer, emphasizing its use in the mathematics classroom. Sample programs to plot dots and diagonals as well as programs for creating more complex visuals and patterns are included. (JN)

The Logo programing language is described. Why it is useful is discussed, followed by an illustrative activity using Logo. (MNS)

Discusses the place of descriptive geometry in schools problems of teaching technical graphics to young students. Instructional materials for teaching technical graphics, graphic programs, program development, and the value of school project work are considered. Sample computer-generated drawings are included. (JN)

Presents a computer program (Atari basic) called Animath (animated math program). A modified character set is to create a sauntering gorilla who, for example, jumps up and down when a problem is correctly solved. Extensive documentation is included. (JN)

Presents a lesson developed for a Montessori Elementary Level II class using the Turtle Math program. Students used mathematics, geometry, and logical thinking to identify the basic formula for drawing stars with any desired number of points. (KB)

It is more important for children to learn concepts in mathematics than to be able to perform automatic computational functions. By permitting manipulation of the relationships among visible objects, computer graphics can make it easier for students to grasp concepts and can serve as an essential ingredient in effective computer-assisted…

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)

The use of a computer software package called "Exploring Measurement, Time and Money--Level 1" to help children explore many different arrangements of data and the effects of changing that data is presented. Activities which may be used to prepare students for this instruction are described. (CW)

Use of background grids from Logo programs is involved in this activity on angles and slopes. The value of such activities is then discussed. (MNS)

PROLOG is a relatively new programing language with graphics capability. In addition, the language has a declarative rather than a procedural structure. Two programs illustrating use of the language in the mathematics classroom are presented. (JN)
