Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

Achievement in science depends among other factors on hypothetico-deductive reasoning ability; that is, on the developmental level of the students.
