Calculators: To Use or Not to Use

Should students use calculators or not?  Research supports the use of calculators especially for multiple step problems.  Many multiple-step problems are scored incorrect due to the increased opportunity for errors when using large numbers.  How many of us want to multiple 304 x 213 without a calculator?  Not me. An example for recommended use of a calculator would be division problems exceeding two digits into four digit combinations.  Research also indicates that understanding of algebraic concepts are enhanced when calculators are used.

Only about 1/3 of secondary educators allow use of a calculator and only 1/2 of special educators allow the use of a calculator for students with mild disabilities when completing multiple-step problems.

Important notes:

  1. Teach kids how to use a calculator, don't assume they know how to use one.
  2. When evaluating special education students who have used a calculator for several years, consider allowing them to use one on reevaluations.  Proficient calculator usage is a positive aspect to report on.
  3. Make the recommendation for use of calculator for multiple-step problems and large number computations.
