The Relationship Between the Proportional Reasoning Ability of Ninth Graders and Their Achievement of Selected Math and Science Concepts.
McBride, John W.; Chiappetta, Eugene L.
Investigated was the relationship between proportional thinking and students' ability to demonstrate knowledge and understanding of concepts related to simple machines, structure of matter, and equivalent fractions. The study involved a random sample of 136 ninth-grade physical science students. Each student's proportional reasoning skills were assessed using two Piagetian tasks: the Balance and the Quantifications of Probabilities. The students were classified into four groups according to their proportional reasoning ability. Students' achievement of the selected science and mathematics concepts was assessed at the knowledge, comprehension, and application levels using a paper/pencil test. The study indicated that proportional reasoning appeared to be an underlying factor associated with achievement of simple machines, structure of matter and equivalent fractions concepts among ninth-graders. Achievement of the concepts increased as proportional reasoning increased. Also, as the general level of achievement increased, proportional reasoning appeared to be more critical for understanding subject matter. (Author/GA)
