THIS PAPER DISCUSSES THE SELECTION OF A PEDAGOGICAL NORM FOR FRENCH INTERROGATIVE STRUCTURES. SINCE THIS AREA OF FRENCH GRAMMAR IS PARTICULARLY POLYMORPHOUS, OBJECTIVE CRITERIA ARE SET UP TO MAKE THE SELECTION--FREQUENCY, COMPLEXITY, AND EXTENSIVITY. BECAUSE "EST-CE QUE" CAN BE APPLIED WITHOUT EXCEPTION TO ALL TYPES OF KERNEL SENTENCES, IT WAS CHOSEN AS THE PEDAGOGICALLY PRIMARY INTERROGATIVE STRUCTURE. QUESTIONS INVOLVING INVERSION AND OTHER LESS EXTENSIVE PROCESSES SHOULD BE INTRODUCED GRADUALLY AS THE STUDENT PROGRESSES. THIS ARTICLE APPEARED IN "THE INTERNATIONAL REVIEW OF APPLIED LINGUISTICS IN LANGUAGE TEACHING," VOLUME 5, NUMBER 1, MARCH 1967, PAGES 3-10. (AF)
