This guide explains how to incorporate a local area network (LAN) into the business education curriculum. The first section defines LAN, a communications system that links computers and other peripherals within an office or throughout nearby buildings and shares multiuser software and send and/or receive information. Curriculum planning considerations are discussed, followed by a discussion of four levels where networking is used in the curriculum: individual classes, electronic processes to network classes, networked systems incorporated in other classes and/or other schools, and curriculum support of school administration needs. The introductory course outline consists of two sections: (1) Introduction to Electronic Communications--basic communication skills, communication modes, and applied communications; and (2) LAN Software Functions--electronic mail, electronic filing, electronic calendars/scheduling, and electronic conferencing. Student application exercises are described next. They cover the following topics: (1) Electronic Mail--messages, memoranda/business notes, and document suggestions; (2) Electronic Filing, (3) Electronic Calendaring, and (4) Electronic Conferencing. Five appendixes are included: selected list of 78 publications; list of 103 simulations by publishers; 9 computer activities (banking and finance); Sports Spectrum electronic files; and proposed software using Sports Spectrum flow-of-work simulation.
