Web 2.0: What is it and useful tools for educators - a flogram

Why should Math Educators care?

  • many students are users of these tools and subscribe to the basic core values - some of which are at odds with school values:
    • knowledge resides in the community rather than among the experts
    • knowledge is unlimited and residing on the Web rather than knowledge being scarce
    • learning is a social endeavor rather than submission to a syllabus
    • multimedia, hyperlinked, mashed up productions preferable to text
    • user interest/passion determines topics not course outline
  • Web 2.0 provides access to useful resources
  • Teachers are experimenting with using Web 2.0 tools with their students
    • wiki textbooks
    • journals using blogs
    • podcasting
    • social bookmarking
    • photo and video sharing
  • Web 2.0 tools provide easy ways to develop a web presence, visible to search engines
    • archiving of content
    • communicate with students, parents colleagues
