This guide, updated for use with the Sixth Edition of the Publication Manual of the American Psychological Association®, is designed to help improve students' understanding and use of APA Style® before they begin writing term papers and research reports, allowing instructors in academic settings to concentrate more on course material and less on correcting style errors in students' papers. Mastering APA Style: Instructor's Resource Guide contains eight multiple-choice assessment surveys, correction keys, and answer sheets, along with informative instructions on how to incorporate this material into a curriculum. This essential APA Style resource also enables editorial trainers to help copy editors polish their skills as they gain a thorough knowledge of APA Style and the Publication Manual. Included within each mastery test are multiple test questions relating to key APA Style points on references and citations, grammar, headings, serialisation, statistical and mathematical copy, italics and capitalisation, numbers style and table formatting. This guide is an effective learning tool for instructors and students to use in the classroom or as guided or independent study.
