Each teacher who participates as a Fellow in a League Teachers Institute seminar or a national seminar prepares a curriculum unit to teach the following year and to share with other teachers. Since the inception of the New Haven Institute in 1978, Fellows have written 1,856 curriculum units in the humanities and the sciences. Since 2006, Fellows in the Teachers Institute of Philadelphia have written 275 curriculum units. In 2011, Fellows in the new Delaware Teachers Institute in New Castle County wrote 27 curriculum units.

Beginning in 2005, teachers from Institutes and school districts participating in the Yale National Initiative have become National Fellows and have developed curriculum units through national seminars.

These local and national units contain five elements: content objectives, teaching strategies, sample classroom activities, lists of resources for teachers and students, and appendices on the school district academic standards the units implement.

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