In the past, students who knew only a little English (called limited English proficient, or LEP), were usually taught only low-level science and mathematics. Now, new science and mathematics teaching methods can help LEP students get a good education in both fields. This guide will help parents know if their children are learning as much as possible. A preschool curriculum should make connections between the children's present lives and the lives of their ancestors and should draw on experience with plants and animals and nutrition and health instruction. Elementary and high school science lets students see and feel the meaning of the words instead of just hearing descriptions. Science taught to LEP students should be the same as that taught to others, and examples from the students' cultures should be used to make science learning easier. Use of common themes and cultural awareness can make improving English an accompaniment to science instruction. Group work, the application of mathematics, and the use of computers can all help an integrated program that teaches students science, mathematics, and English together. (SLD)
