REPORTED ARE TWO STUDIES OF THE NEWTON, MASSACHUSETTS EDUCATION DEVELOPMENT CENTER. IN ONE STUDY DATA ON WORKSHOPS TO ACQUAINT HIGH SCHOOL PHYSICS TEACHERS WITH NEW SCIENCE CURRICULUM MATERIALS ARE REPORTED. THE WORKSHOPS WERE HELD AT 23 AREA MEETINGS AND ATTENDED BY 755 HIGH SCHOOL SCIENCE TEACHERS DURING THE 1966-67 SCHOOL YEAR. THE WORKSHOPS INVOLVED A TWO-HOUR PRESENTATION AND DISCUSSION ON THE (1) HARVARD PROJECT PHYSICS (HPP), (2) ELEMENTARY SCIENCE STUDY (ESS), (3) INTRODUCTORY PHYSICAL SCIENCE (IPS), AND (4) INTERMEDIATE SCIENCE CURRICULUM STUDY (ISCS). DATA INDICATED (1) THAT HIGH SCHOOL PHYSICS TEACHERS PROFIT FROM EXPOSURE TO NEW SCIENCE CURRICULUM MATERIALS, INCLUDING THOSE DESIGNED FOR THE ELEMENTARY SCHOOL, AND THAT IN SOME CASES, THIS EXPOSURE RESULTS IN THE DEVELOPMENT OF WORKSHOPS FOR OTHER SCIENCE TEACHERS AND THE USE OF THE NEW MATERIALS BY ELEMENTARY AND JUNIOR HIGH SCHOOL TEACHERS, AND (2) THAT THERE ARE MANY SOUND SCIENCE COURSE MATERIALS, BUT THAT THESE NEW MATERIALS ARE NOT WIDELY USED. THE SECOND STUDY INVOLVED HIGH SCHOOL STUDENTS TEACHING ELEMENTARY SCHOOL STUDENTS USING THE NEW SCIENCE CURRICULUM MATERIALS. SPECIFICALLY, 16 HIGH SCHOOL PHYSICS STUDENTS TAUGHT ESS UNITS IN THE ELEMENTARY GRADES, ONE HOUR, THREE DAYS A WEEK OVER A PERIOD OF THREE WEEKS. THE RESULTS DID NOT GIVE CLEAR-CUT ANSWERS TO ANY OF THE QUESTIONS INVESTIGATED. (DS)
