  • This is the questionaire for the teachers. I’m not even going to report any of the responses (because there aren’t enough to mean anything) but I can say that the responses have been very positive. They have been things like, “Thanks for helping me to get my students to interact with people that I couldn’t have gotten into my classroom otherwise.”
  • I’m looking specifically at the process and the possibilities of using web-based videoconferencing. But I hope that in the future I (or someone else) can look at specific curricular implications of this technology

    14. 14. Pilot Project Goal: Find an economic and effective way to connect students anywhere with experts from around the world Assumption #1 There are “experts” in the field that would be willing to speak to students in remote areas Assumption #2 The “experts” are not willing to put in the time and costs involved with traveling to a school without any compensation.

    16. 18. Evaluation - Teacher Questions <ul><li>How do you think the videoconference presentation of the material changed student performance? </li></ul><ul><li>How does this method compare to traditional (face to face) presentation? </li></ul><ul><li>Were students as interested in the presentation as if the presenter had been in the classroom in person? </li></ul>
    17. 19. Evaluation - Presenter Questions <ul><li>How do you think the videoconference presentation of the material changed student performance? </li></ul><ul><li>How does this method compare to traditional (face to face) presentation? </li></ul><ul><li>Were students as interested in the presentation as if the presenter had been in the classroom in person? </li></ul>
    18. 20. Study Plans <ul><li>Between 20-30 participating teachers from US/international sites </li></ul><ul><li>Question #1: Does web-based videoconferencing compare to traditional (face to face) instruction? (Data from teacher and presenter responses) </li></ul><ul><li>“ To take an ironic example, the Bill and Melinda Gates Foundation's &quot;State Challenge Grants for Leadership Development&quot; are remarkable for their de facto endorsement of the status quo ante (Microsoft) in adult learning. Yes, PowerPoint has replaced overhead transparencies, but the foundation's technology leadership development activities still rely on convening educators face to face—school people as passive spectators in a delivery mode older than DOS. </li></ul><ul><li>Question #2: Do teachers perceive the potential for curriculum changes based on the use of web-based videoconferencing (data on teacher’s perception of curriculum change possibilities as a result of the technology) </li></ul>
    19. 21. Future Possibilities <ul><li>Student to student (e-pals) </li></ul><ul><li>Teacher training </li></ul><ul><li>Classroom observation </li></ul>
