This paper explains how educational technology and multimedia materials can enhance teaching and learning for today's diverse students. The United States still carries the Puritan influence in education (attempting to build a single culture), with little recognition of the need to address diversity in California's K-12 classrooms. Recently, California legislative mandates developed a policy of banning curriculum materials in Spanish, yet in over half of all California school districts, 20 percent of students are non-English speakers. Data on changing ethnic compositions and achievement scores show that discrimination has not disappeared. Teachers must understand and recognize the prejudicial myths and stereotypes embodied in the dominant U.S. culture. A significant impediment to multiculturalism is the dysconscious racism that still lingers in the dominant culture. It is important to investigate different cultures to get away from negative stereotypes. Multimedia and computer technologies provide the capacity for presentations with high-tech graphics and engaging interactivity. Teacher training can focus on relatively low-cost, new multimedia technologies to enhance learning. Multimedia instructional materials address different learning styles and allow congruence and cultural consonance with learning styles. Modern technology can enhance the social construction of knowledge. (SM)
