Down-sizing in DOS

摘要

MENU is a DOS-based set of C programs which permit an instructor to create interactive computer-aided learning modules on any subject. Less than a megabyte in size, the controlling program permits a teacher with no formal computer training to prepare and modify all elements of the module---topics, subject matter, sequencing and the availability of computer tools and devices. The program displays all materials immediately and permits spontaneous and continuous modification in creation mode where lessons can be linked to each other in larger units, run separately and linked to any executable, batch or graphics files to permit easy integration of other CAL and computer facilities. Users work within, and can be tested on, each MENU lesson and students can become participants in lesson creation and the preparation processes and of any text files within them. A "definition" option permits instructors to expand on and enrich terms within a file or globally throughout the lesson and to link ideas throughout the module.

MENU is designed to run on very basic systems to support individuals in the preparation and learning of subject matter and to be integrated into large networks, with tutorial and mail facilities, for classes and students working on group projects. Hyperlinks permit connections among all levels of information and across topics. Help facilities are context-specific and can be created or modified by instructors at each point in the module. The creation elements include display screens, an ascii editor for both lesson creation and as the medium through which instructors and users prepare information within the lessons. Instructors can adapt, modify and expand existing materials and link these to larger modules and all movement within the lesson is accomplished by the cursor. ESC and Enter keys or a mouse. The .dat file within the MENU program permits instructors to make direct connections to display files as their familiarity the creation process increases.

MENU permits instructorsto create materials specific to their needs and teaching style, to integrate existing lessons, tools and subject matter into modules relevant to their courses and to quickly incorporate students in the preparation of both subject matter and the structuring of lessons for their own projects and to prepare materials for other classes.
