Fast and accurate control of the information flow is vital for active reading. Mathtalk uses structured browsing functions and a specially developed command language to achieve this active reading. Finally, an audio glance called algebra earcons is introduced that enables readers to get a high-level view of an expression and plan the reading process. The models can be customized and used for educational and research purposes. Several models built using four different scales are described.
Surface textures are varied to allow atom types to be distinguished.
The nature of computers as information processing tools, the role of computer technology in user-friendly interactive learning environments, and the possibility of designing instructional tools to meet individual needs of students, make computers potentially powerful tools for assessment. Computer-based assessment applications used in science, such as Computerized Adaptive Testing, Figural Response Item Testing, Computer Simulations, and Anchored Assessment can be appropriated for assessing students with learning disabilities. All rely on the availability of information in high-level electronic form. A brief review of methods for storing high-level information and an example of their use in printing Dotsplus documents are given. Technology can have a positive affect on all of these factors and help open doors to new areas of study and employment.
