Calculators, Computers, and Classrooms.

Suggestions for using four-function calculators, programmable calculators, and microcomputers are considered in this collection of 36 articles. The first section contains articles considering general implications for mathematics curricula implied by the freedom calculators offer students from routine computation, enabling them to focus on results and relationships, and is balanced by Section Two, exploring inappropriate ways calculators can be used. Freedom from thinking about routine calculations provides freedom for thinking about problem solving is the theme of Section Three. Articles in Section Four include some specific lesson ideas for using calculators in the classroom. Section Five focuses on programmable calculators. Section Six contains articles which consider ways in which microcomputers can be introduced into schools, addressing physical, economic, and political issues. Section Seven explores implications of the computer on mathematics curricula, considering both new topics and new approaches to old topics (such as computer assisted instruction). Computer literacy is the theme of Section Eight, suggesting that although all students need to know about computers, "what" they need to know is debatable. The ability to simulate real-world events (computer simulations) is considered in the final section, suggesting that this ability opens new areas for mathematical exploration. (Author/JN)
