UNITS CONTAIN DESCRIPTIONS OF COURSE CONTENT AND SUCCESSFUL TEACHING METHODS, SUGGESTED DISCUSSION QUESTIONS, AND EXERCISES FOR THE TEACHER'S USE IN PRESENTING THE SUBJECT MATTER. PROCEDURES ARE SUGGESTED BY WHICH STUDENTS MAY SPECULATE ABOUT THE NATURE OF LANGUAGE AND FORMULATE INDIVIDUAL DEFINITIONS OF IT. THE FOLLOWING UNITS ARE INCLUDED--"WHAT IS LANGUAGE,""SO WHAT'S A DICTIONARY FOR,""HOW WORDS ARE FORMED,""HOW WORDS CHANGE MEANING IN TIME AND CONTEXT,""AN INTRODUCTION TO PHONETIC ALPHABETS AND TO MORPHEMES THROUGH PREFIXES AND SUFFIXES,""AMERICAN DIALECTS,""WHY WORRY ABOUT MEANING,""A SUGGESTION FOR A UNIT ON THE HISTORY OF THE ENGLISH LANGUAGE,""LEXICOGRAPHY FROM CAWDREY TO 'WEBSTER'S THIRD'," AND "NOTHING MOVES WITHOUT TRANSLATION."
