PROJECT ENGLISH AT PURDUE PRODUCED 14 "OPUS-CENTERED" UNITS INTEGRATING STUDIES OF LITERATURE, LANGUAGE, AND COMPOSITION. FIELD TESTING IN READING, WRITING, SPEAKING, LISTENING, AND REASONING INVOLVED OVER 1800 INDIANA, KENTUCKY, AND OHIO SEVENTH-GRADERS RANGING IN IQ FROM 80 TO 130, FROM ALL ABILITY LEVELS EXCEPT READERS RETARDED MORE THAN THREE YEARS BELOW GRADE. MEASUREMENTS INCLUDED PRE- AND POST-TESTS ON EACH UNIT, SEQUENTIAL TESTS OF EDUCATIONAL PROGRESS (STEP) TESTS IN READING AND WRITING, AND SIX INTERPRETIVE-EXPOSITORY ESSAYS. THE PURDUE ENGLISH STAFF RATED 5400 ESSAYS EACH YEAR ON A 20-POINT SCALE, AND RESULTS OF 1965-66 WERE REPLICATED IN 1966-67, SHOWING STEADY PUPIL PROGRESS ON THE FIRST FOUR PAPERS, WITH GAINS MAINTAINED ON THE FIFTH AND SIXTH PAPERS. PUPILS FROM HIGH, LOW, AND MIDDLE SOCIOECONOMIC GROUPS PERFORMED ALIKE. RESULTS OF OTHER TESTS WERE ALSO POSITIVE EXCEPT FOR THE STEP TESTS IN WRITING MECHANICS ON WHICH EXPERIMENTAL GROUPS DID NO BETTER OR WORSE THAN CONTROL GROUPS. THE 10 MOST SUCCESSFUL AND POPULAR UNITS AMONG PUPILS AND TEACHERS (IN ORDER OF DIFFICULTY FROM LOW TO HIGH) WERE "AESOP,""VISIT TO A SMALL PLANET,""DIARY OF A YOUNG GIRL, "HIROSHIMA,""TREASURE ISLAND,""THE YEARLING,""EVANGELINE,""THE BOOK OF ESTHER,""A MIDSUMMER NIGHT'S DREAM," AND "THE ODYSSEY."
