The following lectures are included in this volume: Needed: "Turned on" Teachers; The Most Important Advantage; HILT: High Intensity Language Training; The Education Gap: Why Mexican American Children Fail in School; The Mexican American Heritage; The Invisible Poor: The World of the Migrant; and Emergence of the Mexican American. The lectures have been selected from those presented as part of the pre-service phase of a 2-year Teacher Corps training program designed to create understanding of cultural differences and to define the teacher's newly emerging role as a translator of community expectations for Spanish-speaking migrants, seasonal farm workers, and others who are disadvantaged.
