Israeli Jewish and Arab experts within Israel have developed innovative intergroup relations programs, educational efforts designed to improve relations between Israeli Jews and Israeli Arabs. Social scientists, educators, and practitioners on both sides of the Arab-Jewish conflict have dedicated themselves to lessening the hostility between these two groups within Israel through coexistence educational training. This issue presents theory, methods, and data from these coexistence educational programs. The introductory article presents a brief history of this conflict; the groups' differing perceptions regarding the dispute; some information about the role of culture, socioeconomic status, and ethnicity in the discord; and some of the social psychological processes that perpetuate and recreate the hostilities. Last, it provides a brief preface of this issue's articles.
