The Pittsburgh Teachers Institute, through its seminars, offers teachers the opportunity to develop curriculum units for their classrooms while drawing on the academic expertise of college and university professors and utilizing the research facilities of higher education institutions. Each curriculum unit is utilized by its author in the year immediately following the seminar in which it was developed. In addition, all curriculum units are made available for use by other teachers by placing them on-line here (each year the units are also bound and distributed to all Pittsburgh public schools).
