These guidelines were developed to provide assistance to Alberta schools in the development of policy for the use of calculators in classrooms, and also to provide some assistance to teachers in planning appropriate experiences for students. A position statement advocating the use of calculators as both instructional and computational aids is presented. Guidelines for their use are then given by level (primary, intermediate, junior high, high school). A research summary is included as Appendix A; Appendix B contains suggestions for calculator selection; Appendix C details the National Council of Teachers of Mathematics recommendation on calculators; and Appendix D provides summaries of some individual research reports. Finally, Appendix E presents the policy statement on the use of calculators on provincial examinations. (MNS)
