Arguing that the most effective types of managerial computer software for teacher use are word processing, database management, and electronic spreadsheet packages, this paper uses Apple Writer, PFS File, and VisiCalc as examples of such software and suggests ways in which they can be used by classroom teachers. Applications of Apple Writer that are described include use as an instructional tool to improve student writing skills; the design of form letters and class mailing lists; and the design and formatting of frequently used curriculum materials, including written examinations, syllabi, outlines, biographies, and assignments. Suggested applications of PFS File include the creation of longer mail lists; creation and sorting of class lists with students' addresses, parents' names, grades, and assignments; and generation of address labels. Uses for ViciCalc include keeping records of student grades and averaging grades at report card time. Samples of some materials produced using such software packages are attached. (RP)
