gaise use technology for developing concepts analyzing data
GAISE: Use Technology For Developing Concepts & Analyzing Data
  • Not to be used for the sake of using technology
  • Allows students to focus on interpretation, not mechanics
  • Helps students analyze data, visualize concepts, and understand abstract ideas
  • Examples Include:
    • Computer software, graphing calculators, applets, websites, response systems, etc.

Using Technology
  • To help avoid using technology just to use technology consider the Triadic Approach to Technology Assessment

Activity

Technology

Outcome

Flashlight Project, The TLT Group,http://www.tltgroup.org/media/fl/Triad.htm

an example using technology

Desired Outcome

Visualize shape of binomial distribution for different values of n and p.

Recognize convergence of relative frequency to distribution function.

Select Activity

Simulate a binomial experiment 10, 100 & 1000 times.

Vary n and p.

Select Technology

10 Simulations – Low Tech

1000 Simulations – High Tech (Computer Simulation)

An Example: Using Technology

Using Technology Sessions
  • Outline
    • Part I: Analyze Data
      • Demo statistical software
      • Time for project work
    • Part II: Conceptual Understanding
      • Visualization through simulation
        • Software, Calculator, Applets
technologies for analysis
Technologies for Analysis
  • Statistical Software Packages
  • Internet-based (Java) Analysis Tools
    • StatCrunch (www.statcrunch.com)
    • Others
  • Graphing Calculators
  • Computer Response Systems
    • “Clickers”
    • TI Navigator
statistical software packages
Statistical Software Packages
  • Lots of choices – even for intro stat Look for
    • Easy to use – intuitive interface
    • Helps students focus on concepts and interpretation
    • Good price (i.e. student versions)
  • Encourage students to
    • Learn how to use the help menus and
    • Figure out some things on their own
don t forget about
Don’t Forget About
  • Using technology to create reports of their analysis
    • Importing graphs into Word/PowerPoint
    • Exposure to “standards” for writing in their discipline
    • When grading reports, develop a rubric
      • Encourages better reports
      • Important for grading
      • Helps students know what is important

  • What are appropriate ways to incorporate technology into the activity that you are developing?
  • Spend time working on this with your group.
