A guide for teachers, counselors, and administrators of Manitoba high school programs enrolling limited-English-proficient (LEP) students is designed to provide background information and resources for helping these students develop English language skills for success in school and beyond while receiving a sound basic education in a full range of subjects. Guidelines for the reception, orientation, placement, integration, and follow-up of immigrant and Canadian native students in the school are outlined. Recommended course outlines for the English language component of LEP student programs are presented, including two levels of English as a second language, a transitional course, a functional literacy program, and special needs programming. A section on accommodating diverse cultural backgrounds suggests teacher and staff behaviors to support student needs. A language development approach to instructing LEP students in any subject is described, suggesting classroom techniques for enhancing the learning experience. Recommendations are made for developing each of the four language skill areas: listening, speaking, reading, and writing. The concept of language across the curriculum is discussed, and sample literature, science, mathematics, and social studies lessons are provided. A chapter on student assessment is also included, and an appendix contains support materials. (MSE)
