REPORTED ARE THE RESULTS OF A CURRICULUM RESEARCH PROJECT OF THE MICHIGAN SCIENCE CURRICULUM COMMITTEE JUNIOR HIGH SCHOOL PROJECT FOR USE IN TEACHING JUNIOR HIGH SCHOOL UNIFIED SCIENCE. THE COMMITTEE USED PREVIOUS RESEARCH DATA, PARTICULARLY IN THE AREA OF INSTRUCTION AND INQUIRY TRAINING, TO DEVELOP 13 UNITS INCLUDING 55 OPEN-ENDED LABORATORY EXPERIENCES. EACH EXPERIENCE IS DIRECTED TOWARD ONE OR MORE OF 13 INTERDISCIPLINARY IDEAS WHICH ARE GROUPED UNDER TWO BASIC ASSUMPTIONS--(1) SCIENTISTS EXPECT NATURE TO BE DYNAMIC AND TO SHOW VARIATION AND CHANGE, (2) SCIENTISTS THINK OF THE WORLD, AND OF THE PHENOMENA IN IT, AS CONSISTING OF SETS OF RELATIONSHIPS RATHER THAN ABSOLUTES. EVALUATION WAS BASED ON STUDENTS' QUESTIONS SUBMITTED TO THE INSTRUCTOR AFTER THEY HAD COMPLETED INSTRUCTION RELATIVE TO A PARTICULAR IDEA. THESE QUESTIONS WERE THEN DIVIDED INTO TWO GROUPS, THOSE WHICH POINTED TOWARDS THE IDEA AND THOSE WHICH DID NOT. STUDENTS ALSO RESPONDED ON AN OBJECTIVE TEST WHICH REQUIRED THEM TO DISTINGUISH WHETHER A QUESTION DID OR DID NOT POINT TOWARD THE IDEA INVOLVED. FURTHER EVALUATION IS PROJECTED. THEY BELIEVE THAT THIS CAN BE USED, IN WHOLE OR IN PART, WITH ANY CURRICULUM PLAN SO LONG AS THE SUBJECT MATTER INCLUDED CAN BE MATCHED WITH ONE OR MORE OF THE IDEAS INCLUDED IN THE PROJECT MATERIALS. EACH OF THE 13 UNITS IS INCLUDED IN THE TEACHER'S GUIDE. CRITERIA FOR WRITING LABORATORY EXPERIENCES, SUGGESTED PROCEDURES FOR USING THE MATERIALS, AND THE TESTS DEVELOPED WITH THE PROJECT ARE ALSO INCLUDED. (DS)
