The graphing calculator affords the student in analysis a powerful tool to extend visualization, which was previously limited to textbook illustrations and time-consuming constructions. Provides illustrative examples used in initial classroom presentations of several topics including convergence and in student explorations of these topics. (ASK)

Presents three geometric problems from a workshop for in-service algebra teachers to help them make connections between the mathematical concepts that they know and the drawings that they were required to display on their graphing calculators. (ASK)

Describes two stages of potential development that could make multimedia the core of an information infrastructure for educational reform: (1) incorporating hypermedia to enable knowledge construction by learners; and (2) using visualization and virtual communities to create artificial worlds. (16 references) (MES)

Investigates the effectiveness of using trimetric pictorials instead of isometric pictorials on the Purdue Spatial Visualization Test - Visualization of Rotations (Guay, 1977). Records student responses and response times as well as information on gender, current major, and number of previous graphics courses completed. (Contains 18 references.)…

Imaging and visualization tools have assisted Earth scientists in answering age old questions by changing their orientation while reshaping the questions they ask. Imaging and visualization are powerful instructional tools still in the early phases of curricular infusion in the science education setting. This paper calls for a collaboration…

Considers cognitive development in mathematics and its relationship to computer technology with special emphasis on the use of visual imagery and symbols and the later shift to formal axiomatic theories. Presents empirical evidence to show how these forms of thinking are enhanced, changed, or impeded by the use of technology. (Contains 36…

Latest digital technologies play an important role in teaching writing and preparing students to write in the 21st century. The different technologies used to teach writing such as using visual imagery and envisionment are described.

This project description is designed to show how graphing calculators and calculator-based laboratories (CBL) can be used to explore topics in the physics of sound. The activities address topics such as sound waves, musical notes, and chords. Teaching notes, calculator instructions, and blackline masters are included. (MM)

There are several possible approaches in which dynamic computerized environments play a significant and possibly unique role in supporting innovative learning trajectories in mathematics in general and geometry in particular. Describes an approach based on a problem situation and some experiences using it with students and teachers. (Contains 15…

The benefits of visualizing mathematics by using technology such as TI-92+ and mathematically oriented software (DERIVE 5 and CABRI II) are indisputable. On the basis of some examples we would like to show that visualizing techniques can help students to analyse certain mathematical problems better and give them strong support in finding formal…

These proceedings contain the papers of the International Conference on Mobile Learning 2013, which was organised by the International Association for Development of the Information Society, in Lisbon, Portugal, March 14-16, 2013. The Mobile Learning 2013 International Conference seeks to provide a forum for the presentation and discussion of…

The relationship between college students' preferred mode of processing mathematical information--visual or nonvisual--and their performance in calculus classes with and without technology was investigated. Students elected one of three different versions of an introductory differential calculus course: using graphing calculators, using the…

Describes a study conducted in undergraduate science classes in Singapore using computer modeling and simulation. Reports that the use of computer models and simulations proved to be valuable in explaining many aspects of science. Students reported that three-dimensional images helped them in their understanding. Contains 22 references.…

A small class of functions is described that easily lend themselves to two-dimensional and three-dimensional visualizations at the basic calculus level. The intended audience is those educators involved in the instruction of elementary calculus. This note is an educational piece that begins with the question: "What happens if a function defined on…

Geographic information systems (GIS) are computer-based tools for geographic data analysis and spatial visualization. They have become one of the information and communications technologies for education at all levels. This article reviews the current status of GIS in schools, analyzes the requirements of a GIS-based learning environment from…
