This publication presents four suggested language arts curriculum units. They represent a cross-section of materials that have been developed to deal with the learning problems of students with special language difficulties. Originally developed for grades 7-12, these units may be adapted for use in adult education or at other grade levels. They are primarily designed for use with students learning English as a second language, and are directed to the purpose of developing habits of proper usage in English. The four units are: (1) Common and Proper Nouns; (2) Homonyms; (3) Singular and Plural Nouns; and (4) The Use of the Dictionary. Each unit includes: (1) information for the teacher in the form of the principal idea to be communicated, behavioral objectives, and the rationale of the unit, (2) an information sheet which outlines the main points to be taught, (3) exercises, (4) a pretest and a posttest, and (5) the answer key. A bibliography follows the units. (Author/CLK)
