Some blog followers might be interested in an article “Bao et al.’s Comparison of Learning And Scientific Reasoning In Chinese & U.S. Schools: Alternate Conclusions and Recommendations” [Hake (2012)]. The abstract reads:
The features, findings, conclusions, and recommendations of the valuable 2009 Science report “Learning and Scientific Reasoning: Comparisons of Chinese and U.S. students show that content knowledge and reasoning skills diverge” by Bao et al. are summarized.
The primary feature is that Chinese and U.S. students enrolled in introductory physics courses for science and engineering majors in medium-rated universities were tested near the start of classes with the Force Concept Inventory (FCI), the Brief Electricity and Magnetism Assessment (BEMA), and the Lawson Classroom Test of Scientific Reasoning (LCTSR).
The primary finding is that although Chinese students’ averaged scores on the FCI and BEMA indicated good conceptual understanding of basic physics areas, and were, respectively, 1.9 and 2.9 standard deviations above those of U.S. students, their scores on the LCTSR were about the same as those of the U.S. students: at the low end of Lawson’s hypothetical-deductive reasoning range.
Bao et al. draw the conclusion that “current education and assessment in the STEM disciplines often emphasizes factual recall over deep understanding of science reasoning” and recommend that researchers and educators (1) “invest more in the development of a balanced method of education, such as incorporating more inquiry-based learning,” and (2) measure “not only content knowledge but also other factors so as to obtain a more holistic evaluation of students.”
I criticize the Bao et al. report on two counts: (1) the conclusion doesn't follow from the findings; and (2) the recommendations are either ambiguous, problematic, or invalid.
A conclusion consistent with the findings is: Average scores by both Chinese and U.S. freshmen on FCI, BEMA, and LCTSR indicate that K-12 STEM education in both those countries emphasizes factual recall over conceptual understanding and scientific reasoning.
Recommendations that are, in my view, less ambiguous, less problematic, and more valid are: K-12 educators should (1) utilize interactive engagement, inquiry, cognitive enhancement methods, and tests of reasoning; (2) emphasize a few fundamental concepts of STEM; and (3) develop age-appropriate assessments of concepts, epistemological beliefs, learning attitudes, and reasoning so as to formatively assess the effectiveness of their teaching methods. In addition, in the U.S. efforts should be made to (4) reduce poverty, (5) upgrade the education, salary, and prestige of K-12 teachers, and (6) establish National Education Standards.
