ANNOUNCEMENTS - Week 10

16 November 2001

  1. We anticipate that all LITs operating this semester will also run in the Spring. If this is not the case, please let us know immediately. We are planning for about the same number of or slightly more LITs for Spring 2002.

  2. Next week, 19 - 23 November is Break Week. We hope you all have a Happy Thanksgiving. The Week 10 Activities will remain on the DataStreme Homepage and the Daily Weather Summaries will contain a link to a current weather discussion and historical facts.

  3. The Fall 2001 DataStreme course is rapidly approaching the finish line. LIT leaders should be receiving materials for their final course meeting by the beginning of next week. If materials have not arrived by Monday, 26 November, contact DataStreme Central immediately. The materials include certificates and multiple copies of Today's Weather teacher guides, with an answer key, for participants to use in continuing work as Weather Education Resource Teachers. Please review this guide so that you can introduce it to your participants at your final meeting.

    There is also an End-of-Course Survey sent with the final meeting materials that we would like participants to fill out at the final meeting. PLEASE USE ONLY THIS VERSION, NOT one from a previous semester.

  4. Remind participants during the weekly mentoring interactions that this week's, Week 10, Activity A (Monday), included guidelines for writing their Plans of Action that need to be brought to the final meeting and discussed with the group. Also, participants should bring their "portfolio" or archive of materials from the course in their weather bags for review by mentors. You may need to remind them that this should include examples of DataStreme materials they have taken into their classrooms and/or student-generated artifacts that demonstrate use of DataStreme products in the classroom.

  5. The participant course evaluation form will be transmitted directly to participants via the Monday, Week 11, activity files. LIT leaders should make a few extra copies to bring to the final meeting for those participants who may have forgotten theirs.

    Participant evaluations and the final survey must be mailed by the LIT leader to DataStreme Central following the final meeting. With the Week 11 Answer Key we will transmit a separate evaluation form for LIT members so you may comment on the course from your perspective. A "checklist" of tasks for LIT leaders to wrap-up the Fall 2001 DataStreme session will be listed in the Week 11 Answer Key also.
