Schools have introduced numerous programs and activities, intended to recognize the achievements of ethnic groups, in the belief that a multicultural education prepares students for life in an ethnically diverse society and also results in cognitive and affective benefits. Multicultural activities have the following goals: (1) to remedy ethnocentrism in the traditional curriculum; (2) to build understanding among racial and ethnic groups, and appreciation of different cultures; (3) to defuse interracial tensions and conflicts; and (4) to make the curriculum relevant to the experiences, cultural traditions, and historical contributions of minority groups. Studies also indicate links between multicultural education and improved academic achievement for African American and Hispanic American students. Most multicultural learning activities consist of discrete lessons organized around particular events. These activities may be confined to a particular classroom or can involve the entire school. Project Respecting Ethnic and Cultural Heritage (REACH) is a comprehensive, discipline-based multicultural program that infuses information on the history and culture of various groups into the middle school curriculum. Portland (Oregon) and Albuquerque (New Mexico) have also developed programs that integrate multicultural activities throughout the curriculum. The following considerations in developing interdisciplinary programs are outlined: (1) needs assessment; (2) goals; (3) curriculum development; and (4) staff development. A list of nine references and a list of four resources are appended. (FMW)
