Rabbi Gil Perl, head of school at Margolin Hebrew Academy / Feinstone Yeshiva of the South, writes about some of what he learned at the Harvard University’s Independent Schools Institute (ISI), a 3.5 day seminar which he attended along with six other veteran Jewish day school leaders under the sponsorship of the AVI CHAI Foundation. He reflects on a presentation by Professor Richard Weissbourd, a child and family psychologist of Harvard’s Graduate School of Education.
