Research findings on the value of the use of manipulative materials seems clear: they have…

The availability of relatively inexpensive hand calculators and microcomputers is believed to be having an important effect on the teaching of mathematics and science in the United States. The appropriateness of allowing the use of this technology on standardized tests has become a concern of educators and organizations involved in testing.…

A study compared the effects of microcomputer-based software and hand-held calculators on the statistics achievement of 50 graduate students. Results showed no significant difference between computer and calculator groups or between genders but did show an interaction effect. Males using microcomputers outperformed 82% of females using…

To gather information for its response to the issue whether to allow the use of hand-held calculators on standardized mathematics tests, the staff at Educational Testing Service (ETS), under the sponsorship of the College Board, developed a questionnaire to poll teachers of college-level mathematics about calculator and microcomputer use in…
