ANNOUNCEMENTS - Week 2

22 September 2000

  1. Congratulations! Our preliminary estimate is there will be just over 80 LITs operating this semester although course registration forms are just now coming in. We expect this semester will have an enrollment near 600. Leaders should have received an email confirmation of receipt of SUNY registrations from Bob Weinbeck. If not notified and you mailed the forms at least a week ago, please contact DataStreme Central. If you have not yet sent in forms, please have originals mailed immediately and fax copies to DataStreme Central.

  2. By now all mentors should have established a pattern of time and place for interacting with their mentees. While it should be the responsibility of the participant to initiate each week's contact, mentors may need to firmly, but gently, "prod" a few to develop that habit. This early period of the course is critical in keeping participants from falling behind so as to avoid later difficulties. It is also very important to support those teachers who appear to lack confidence in themselves.

  3. We are pleased to have seen quite a few "Reports From the Field" so far this semester. These reports emphasize the human dimension of weather impacts. LIT leaders and members should remind participants that we welcome such newsworthy weather impacts and stories. They may be emailed to Dr. Ed Hopkins (address at bottom of Summary and Supplement files) for possible inclusion in an upcoming "Reports from the Field" section of the Summary.

  4. We are shipping materials (NOAA Weather radios, Hands-On Meteorology, and temperature strips, etc.) to LIT leaders for distribution at the second meeting as we receive registration forms and know of LIT numbers. We must ship based on exact numbers of participants in each LIT in an economical manner. Radios can be given to precollege participants only (NSF regulations), however books should be provided to new LIT members who have not previously received copies.

  5. In response to questions on usage of DataStreme materials by participants, a note was included in this week's (Wk 2) Wednesday, Activity B giving permission for educational use. This notice reiterates the statement of the Preface page to Part B: Applications. Also, participants should consider making copies of activities if they wish to have a "clean copy" for use with their classes.

  6. Due to a changeover of data formats from the University of Wisconsin and difficulties at COMET in updating software, there have been some interruptions in radar and satellites images this past week. We are working with COMET to correct this.
