This unit of the Flexible Learning System (FLS) designed for adults who work with children aged 4-8, offers a means of analyzing, evaluating, and selecting books and other educational materials for use in culturally pluralistic classrooms and with young children of Mexican-American heritage. Research which explores the impact of books on children's self-concept and attitudes toward other ethnic groups is reviewed. Criteria for the analysis and evaluation of written text and illustrations in children's books are presented in two sections. The first section includes guidelines for detecting culturally-negative biases in terms of overgeneralization, evaluative and demeaning statements and ethnic stereotypes. The second section underlines the importance of understanding the history, culture, and language of the Chicano, and focuses on recognizing culturally accurate information, language appropriateness, accurate source and treatment of materials, and factual errors. Each section contains evaluation of pictures and text taken from literature often recommended for use with the Chicano child. The unit concludes with self-assessment activities in which sample paragraphs are presented for revision along the lines specified in the guidelines. Bibliographies are included.
