A mid-1970s survey found that 72 percent of teachers and laypeople did not approve of seventh-grade students using calculators. One concern was the inability to help students understand and identify their errors, for the calculators did not log the buttons that students pressed, making it difficult for teachers to see and correct mistakes. Early research similarly found that parents were worried that their children would become dependent on the technology and forget basic mathematical skills. Doesn’t that sound familiar?
