Transcript

  • 1. Data Tools for Critical Thinking INTC 3610 Fall 2010
  • 2. What is data?
    • Data comes in two basic forms:
      • Numerical – numbers
      • Textual – words
    • Data comes from many sources
    • Let’s brainstorm a few…
      • First open a program called Inspiration
      • Now let’s name sources
  • 3. Where do we get data?
    • Sources include:
      • Existing statistical sites online
        • Real time data sites
      • Repositories of events like encyclopedias and books
      • Our own experiments
      • Surveys and questionnaires
      • All around us in all kinds of forms
        • Text
        • Visuals
  • 4. Tools for Managing Data
    • What is difference between your memory and a computer when it comes to managing data?
        • How many e-mail contacts can you recall from your address book?
        • If you read long speech, how long does it take you to determine the key themes?
        • If you take notes from a lecture, how do you determine the most important information?
  • 5. Tools for numbers
    • Spreadsheet programs like Microsoft Excel
      • Keep track of numerical data
      • Allows you to sort or filter data
      • Allows you create formulas to answer questions
      • Allows you to display and communicate data visually through charts and graphs
      • Also has a way to grab real-time data (search Google for “Real time data sites”)
    • Online programs such as Many-Eyes let you visually represent numerical data in powerful ways
    • Google Maps and Google Earth can utilize data for modeling many types of data
  • 6. Tools for text
    • Inspiration and Kidspiration let you link text
      • Draws out connections
      • Visually shows the important data
      • Add images to enhance understanding
    • Many-Eyes and Wordle are online tools to help express text data visually for analysis
    • Wikis are also a way to capture text data in the form of an encyclopedic form
  • 7. Tools for both text and numbers
    • Sometimes you want to capture both types of data
    • In that case it really requires you to use a database program like Microsoft Access
      • One caveat is that database programs sometimes have steep learning curves to do right
      • Tool Factory has a program for kids that is much easier but costs more
      • Could also use a wiki in a similar manner, but hard to extract the numerical data for further analysis
  • 8. Your Assignment
    • Develop a lesson/activity relevant to your discipline, topic, and grade level that involves data analysis using one of the tools.
    • May want to tie it in with your Web Quest
      • Have students take data collected via the Web Quest and analyze it in support of their task(s)
