An intensive discussion of the immediate phonetic correction approach in second language instruction looks at the rationale for phonetic correction, describes the immediate method, and refines it into seven specific methods. The first chapter, on phonetic correction in general, examines the past and present reasons for using the technique, its ideal function in language teaching, its usefulness, and its history. The second chapter introduces the immediate method by comparing it with the verbo-tonal method, outlining key concepts, facts, and attitudes, and answering specific questions about it: what, when, and how to correct. Chapter 3 presents in greater detail the seven basic methods of immediate phonetic correction: by auditory discrimination, articulatory and acoustical composition, intonation, rhythm, modification, combinatory phonetics, and sensory procedures. Two final chapters provide a brief conclusion and a 175-item bibliography. (MSE)
