As one of five modules focusing on writing skills, this module on punctuation, capitalization, and abbreviations is intended for use in a one-semester course on written communication or as a supplement to other courses where written communication skills are included. The materials, designed so that they may be used in either teacher-directed or individualized learning situations, include learning objectives, notes to the teacher, suggested activities, information sheets, and six assignment sheets for the study of periods, question marks, exclamation points, quotation marks, apostrophes, parentheses, semicolons, colons, commas, capitalization, and abbreviations. Answers to these assignment sheets are provided, as are a pretest, two posttests, and their answers. (RL)
