DESIGNED TO UPDATE THE CONTEMPORARY LANGUAGE TEACHER'S KNOWLEDGE OF THE INNOVATIONS IN HIS FIELD, THIS BOOK INTRODUCES SOME OF THE ESSENTIAL MAJOR AREAS OF WHICH HE SHOULD HAVE AN UNDERSTANDING TO APPROACH HIS WORK SCIENTIFICALLY. PART ONE, DEALING IN GENERAL TERMS WITH LANGUAGE AND LANGUAGE LEARNING, SETS THE TONE OF THE BOOK WITH DISCUSSIONS OF THE RELATIONSHIP OF LANGUAGE TO LINGUISTICS AND CULTURE AND THE LEARNING THEORY FROM WHICH THE NEW SCIENTIFIC APPROACH TO LANGUAGE TEACHING HAS EVOLVED. PART TWO SYSTEMATICALLY TREATS SUCH MODERN PRINCIPLES OF LANGUAGE TEACHING AS--(1) THE UTILIZATION OF LINGUISTIC KNOWLEDGE IN THE CONTROL OF THE SOUNDS AND STRUCTURES OF TARGET LANGUAGES, (2) THE ASSOCIATION OF LEXICAL UNITS WITH CONTENT OR MEANING, (3) THE POSTPONEMENT OF THE INTRODUCTION OF READING AND WRITING SKILLS UNTIL AFTER THE BASIC LANGUAGE HAS BEEN CONTROLLED AUDIOLINGUALLY, AND (4) THE USE OF TESTING TECHNIQUES APPROPRIATE TO THE LINGUISTIC PROBLEMS BEING TESTED. RELEVANT TO TECHNOLOGICAL TEACHING DEVICES, PART THREE DISCUSSES THE LANGUAGE LABORATORY, VISUAL AIDS, AND TEACHING MACHINES AND PROGRAMED LEARNING. A GLOSSARY OF USEFUL TERMS, A BIBLIOGRAPHY, AND A CHART OF THE MODERN LANGUAGE ASSOCIATION QUALIFICATIONS FOR SECONDARY SCHOOL LANGUAGE TEACHERS COMPRISE THE APPENDIXES.
