					                   What Is it?
• Calculators are a very
    important technology
    found in the
    classroom
•   They have many
    positive aspects in the
    classroom
•   Calculators also have
    some negative effects
    on students
The Debate




 The Debate
        Why is it Important?

• Calculators are tools used to solve
 problems faster

• Students can answer problems more
 accurately
Why is it Important Continued…

• Calculators can be handheld or found
 online

• There are many lessons that teachers can
 use that involve calculators
   Classroom Example



Example: Parabolic Shapes Video
               Research
            Positive Aspects
• Calculators save time when it comes to
 solving problems quickly

• This leads to giving students more time
 for learning
              Research
    Positive Aspects Continued…
• Calculators give students more confidence
  – Students who are not confident in their own
    abilities can use a simple calculator and
    receive an answer
• Students who used calculators everyday
 scored higher on the SAT’s than students
 who did not
                Research
             Negative Aspects
• Students are not learning the basics
  – Students in the lower grades are using calculators
    and are not learning the underlying concepts of math
• Students confidence will suffer when the
  calculator is taken away
  – Students do not always have the opportunity to use a
    calculator and when they are dependent on a
    calculator, their confidence is lowered when they do
    not have it
              Research
    Negative Aspects Continued…
• A lot of teachers do not know how to use
  the calculator in a lesson
  – Because of this, students are at a
    disadvantage
• Students are losing skills
  – Students are solely using the calculator
    instead of using pencil a paper techniques
 Overcoming the Negative Aspects

• The calculator is really just a tool
  – Students do not need them, calculators just
    help
  – Students need to be taught whether using a
    calculator or using their head is more
    appropriate
 Overcoming the Negative Aspects
          continued…
• Students need to be taught the basic
 methods
  – Math builds upon what students already know
  – Students that do not know multiplication will
    have trouble with factoring
• Teachers also need to be taught how to
 use calculators in lessons
                  Myths

• There are a lot of myths about calculator
  use
• Schools are getting questions from
  parents
• Schools are responding with newsletters
School Letter to Parents




     Calculator Myths
                 Conclusion
• “The calculator should
  be used as a
  supplement to
  learning, not as a
  replacement for
  learning
  computational
  algorithms.”
  (McCauliff )
