Numbers of K-12 teacher participants and K-12 student participants who received NASA-affiliated GLOBE training and subsequently participated in data collection during fiscal years 2003 - 2011 (October 1 - September 30 of each year).
GLOBE is able to confidently report the number of teachers trained by the GLOBE community each year. However, GLOBE is not able to provide exact figures representing student participation due to the presence of unknown variables such as whether each GLOBE teacher is teaching only one classroom of students or teaches multiple classrooms (such as in middle school/high school settings), and given this, we realize that this statistic can also change over the course of a given year. Therefore, the student estimates provided below are extremely conservative estimates, assuming that teachers only work with one classroom of students, using 25 students as the average classroom size. Please note that GLOBE promotes a "team" approach to implementation within schools (forming teams of teachers within each school instead of past models that concentrated on training one teacher per GLOBE school).
We believe that the proper way to characterize these results would be:
"Total number of teachers who received recognized GLOBE training in the Fiscal Year (Oct 1 - Sep 30) and whose school then participated in GLOBE data collection."
* The green cells in the table indicate a switch on June 30, 2012 to a new GLOBE database and a new methodology of metric gathering.
** The light blue cells for 2013 in the table indicate the migration of schools and teachers to a new GLOBE database, and based on functional email addresses.
