Each teacher participating as a Fellow in a League Teachers Institute seminar or a national seminar prepares a curriculum unit to be taught the following year, and to be shared with other teachers. Since the inception of the New Haven Institute in 1978, Fellows have written 1,694 curriculum units in the humanities and the sciences. Between 1999 and 2008, Fellows in the Houston Teachers Institute wrote 688 curriculum units in the humanities and the sciences. In 2006 and 2007, Fellows in the Teachers Institute of Philadelphia wrote 78 curriculum units in the humanities and the sciences. These units contain four elements: objectives, teaching strategies, sample lessons and classroom activities, and lists of resources for teachers and students.

Beginning in 2005, teachers from cities participating in the Yale National Initiative became National Fellows and developed curriculum units through national seminars.

We encourage teachers who use these curriculum units to provide comments on the worth of the units and on student response. Selected comments by unit users will appear on the Yale National Initiative Web site.
