Describes the use of a soroban, a base-10 computer which is a relative of the Chinese abacus, for developing concepts of number sense, place value, operation sense, and mental computation. Provides pictures of the soroban. (MKR)

A study of 331 elementary school children tested the reliability of a computer resident interactive arithmetic test and found high levels of reliability, using single sitting and parallel forms methods. The study also tried to determine the validity of the interactive test by comparing it with arithmetic subtests of the Key Math Test (KMT). (PEN)

Presents information on a project to promote young students' mathematical thinking in which teachers attempt to explore ways to foster students' mathematical development by watching a CD-ROM containing student interviews. Discusses the role that technology might play as a catalyst for teachers to reflect upon their teaching experiences against the…

Examines the idea that the arithmetic calculator can act as a cognitive tool, supporting the amplification or reorganization of systems of thought. Examples were found in which use of the calculator helped pupils work with unusual problem representations and adapt solution strategies in which they focused on planning and monitoring computations…

Three activities which require a calculator with integer division capabilities are presented. In each activity, procedures and questions for discussion are included. Game boards, samples, and answers are included where appropriate. (CW)

The Calculators and Mathematics Project, Los Angeles (CAMP-LA), funded by the National Science Foundation for developing use of technology in the classroom, developed curriculum materials focused solely on the use of calculators in three stages. The first stage studied the mathematics curricula from different states and identified topics that are…
