PARTICIPANTS IN THE 1966 NDEA LANGUAGE INSTITUTE HELD AT WEST VIRGINIA UNIVERSITY WERE THOSE SECONDARY SCHOOL TEACHERS WHO HAD PREVIOUSLY ATTENDED AN NDEA INSTITUTE FOR ADVANCED TRAINING IN THEIR PRINCIPAL LANGUAGE TEACHING FIELD, BUT WHO FROM CHOICE OR NECESSITY HAD BEEN ASSIGNED FRENCH OR SPANISH AS A SECOND TEACHING FIELD. THE REPORT OF THIS INSTITUTE DESCRIBES THE PLANNING OF THE INSTITUTE, SELECTION OF PARTICIPANTS, CONTENT OF COURSES, AND INSTRUCTIONAL PROGRAM. THE PROGRAM REPORT EMPHASIZES THE VARIETY OFFERED BY THE FOUR DEMONSTRATION CLASSES IN WHICH DIFFERENT SETS OF MATERIALS WERE USED, OPPORTUNITIES WERE OFFERED FOR PRACTICE TEACHING, SPECIAL HELP WAS GIVEN TO PARTICIPANTS IN LINGUISTICS AND METHODOLOGY, AND SOLVING PROBLEMS PECULIAR TO THE TWO-LANGUAGE TEACHER WAS DISCUSSED. ROSTERS OF STAFF AND PARTICIPANTS, ALONG WITH SCHEDULES OF BOTH THE INSTRUCTIONAL PROGRAM FOR THE SPANISH AND FRENCH SECTIONS AND THE EVENING PROGRAM OF LECTURES AND FILMS WERE INCLUDED. (AUTHOR/AM)
