Presents a comparison of Thai and American fifth and eighth

Control group students (receiving descriptive, non-inquiry science) and experimental group students (using Science Curriculum Improvement Study-SCIS "Interaction and Systems" materials) were later combined in grade 4 for instruction with SCIS "Subsystems and Variables" materials. Results show similar difficulties in learning…
