Calculator use in the mathematics classroom

  1. 1. Calculator Use in the Mathematics Classroom By: Christina Jowell
  2. 2. <ul><li>Is the use of a calculator taking away from students learning the math? </li></ul><ul><li>Should calculators only be used in a secondary math classroom? </li></ul><ul><li>Is the use of calculators preparing our students for the future of math? </li></ul><ul><li>Are calculators enhancing or hindering learning? </li></ul>
  3. 3. Problem Statement <ul><li>The purpose of this research is to compare research to show calculator use in a mathematics classroom can enhance student learning and the benefits to our students learning to use a calculator. </li></ul>
  4. 4. The significance of this research <ul><li>To know the positive outcomes of using a calculator in the classroom </li></ul><ul><li>To know effective strategies to using a calculator in the classroom </li></ul><ul><li>To know the purposes of teaching students how to use a calculator </li></ul>
  5. 5. Calculators in the classroom over time <ul><li>First affordable basic calculators were widely used in classrooms </li></ul>First graphing calculators used in the classroom Basic hand-held calculator first used in a classroom 1970’s 1980’s 1985 The abacus was widely used before calculators came along More on the history of calculators
  6. 6. According to the National Council of Teaching Mathematics (NCTM) <ul><li>“the use of calculators along with the traditional paper-and-pencil instruction enhances the learning of basic skills.” </li></ul><ul><li>“the integration of the calculator into the school mathematics programs at all grade levels in class work, homework, and evaluation” is something the NCTM supports. </li></ul>
  7. 7. Benefits to using a calculator <ul><li>Allows students to focus on problem solving rather than the basic computations </li></ul><ul><li>Allows students to try new math concepts they may not have tried because of the computations involved </li></ul><ul><li>Makes students more confident in their abilities </li></ul><ul><li>Time - students can solve problems at a more reasonable time frame </li></ul><ul><li>Allows students to practice the skill being taught rather than the computations </li></ul><ul><li>Prevents silly mistakes in computation </li></ul><ul><li>Prepares them for the future whether introducing them to a calculator before high school or for a standardized test or for a profession </li></ul>
  8. 8. Evidence of the effectiveness of calculators in the math classroom <ul><li>Children who use calculators on tests have higher scores in both basic computation skills and problem solving. </li></ul><ul><li>Students who use calculators within a mix of instructional styles do not lose their paper and pencil skills. </li></ul><ul><li>Calculator use in the classroom improves the paper and pencil skills of students regardless of their ability levels. </li></ul><ul><li>Those who use calculators in class have better attitudes toward mathematics than children who do not use them. </li></ul><ul><li>- According to a 1986 study done in the Journal for Research in Mathematics Education </li></ul>
  9. 9. How does calculator use in the classroom translate to calculators in the adult world? <ul><li>According to SEDL, a website committed to researching to improve education </li></ul><ul><ul><li>“Even a part-time job at the corner fast-food chain requires the use of a calculator in some form. If schools do not teach students to use these devices from an early age, the rising generation will lack necessary work skills . Calculators are one tool almost every employer expects employees to use. Calculators are ubiquitous in the work world and as important for employees as voice mail and word processing.” </li></ul></ul>
  10. 10. <ul><li>According to www.xpmath.com </li></ul><ul><ul><li>There are over 100 jobs that require calculators for basic mathematics </li></ul></ul><ul><ul><li>There are over 40 jobs that require scientific calculators </li></ul></ul><ul><ul><li>Click on the calculator for a list of jobs that require calculators </li></ul></ul>
  11. 11. Conclusion <ul><li>Though calculator use in the classroom is still under debate with many educators there are many benefits to their use. </li></ul><ul><li>A balance is needed of calculators and pencil-and-paper in the classroom. </li></ul><ul><li>The use of calculators can enhance a math classroom and prepare students for the future. </li></ul>
