Calculator use in the mathematics classroom Calculator use in the mathematics classroom Presentation Transcript

  • Calculator Use in the Mathematics Classroom By: Christina Jowell
    • Is the use of a calculator taking away from students learning the math?
    • Should calculators only be used in a secondary math classroom?
    • Is the use of calculators preparing our students for the future of math?
    • Are calculators enhancing or hindering learning?
  • Problem Statement
    • 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.
  • The significance of this research
    • To know the positive outcomes of using a calculator in the classroom
    • To know effective strategies to using a calculator in the classroom
    • To know the purposes of teaching students how to use a calculator
  • Calculators in the classroom over time
    • First affordable basic calculators were widely used in classrooms
    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
  • According to the National Council of Teaching Mathematics (NCTM)
    • “the use of calculators along with the traditional paper-and-pencil instruction enhances the learning of basic skills.”
    • “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.
  • Benefits to using a calculator
    • Allows students to focus on problem solving rather than the basic computations
    • Allows students to try new math concepts they may not have tried because of the computations involved
    • Makes students more confident in their abilities
    • Time - students can solve problems at a more reasonable time frame
    • Allows students to practice the skill being taught rather than the computations
    • Prevents silly mistakes in computation
    • Prepares them for the future whether introducing them to a calculator before high school or for a standardized test or for a profession
  • Evidence of the effectiveness of calculators in the math classroom
    • Children who use calculators on tests have higher scores in both basic computation skills and problem solving.
    • Students who use calculators within a mix of instructional styles do not lose their paper and pencil skills.
    • Calculator use in the classroom improves the paper and pencil skills of students regardless of their ability levels.
    • Those who use calculators in class have better attitudes toward mathematics than children who do not use them.
    • - According to a 1986 study done in the Journal for Research in Mathematics Education
  • How does calculator use in the classroom translate to calculators in the adult world?
    • According to SEDL, a website committed to researching to improve education
      • “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.”
    • According to www.xpmath.com
      • There are over 100 jobs that require calculators for basic mathematics
      • There are over 40 jobs that require scientific calculators
      • Click on the calculator for a list of jobs that require calculators
  • Conclusion
    • Though calculator use in the classroom is still under debate with many educators there are many benefits to their use.
    • A balance is needed of calculators and pencil-and-paper in the classroom.
    • The use of calculators can enhance a math classroom and prepare students for the future.
