The three-year interdisciplinary curriculum focuses on the study of nations:  their cultures, history, artistic expression, and political, economic and belief systems. Students who graduate from the program develop a cultural awareness necessary for constructive relations and understanding with people of all nationalities.  This interdisciplinary curriculum forms the core program of BIHS, and covers two or three periods of a student’s day.  During the remaining periods, in addition to the option of taking electives during periods zero or seven, BIHS students select from the array of courses offered in the comprehensive school.  Students thus have flexibility in taking elective classes while benefiting from a smaller school environment. Moreover, a more integrative program suits the BIHS curriculum, which emphasizes collaboration and the construction of knowledge through well-founded pedagogical principles that are most effectively implemented when supportive and trusting relationships exist among teachers and students who know each other well.
