博士 === 國立師範大學 === 科學教育研究所 === 82 === The purpose of this study was threefold: to differentiate the narrow and the wider definition of anomaly from to analyze their different functions in science development; to design experimental activities based on the narrow and the wider definition of anomaly to explore how students engaged in argument to anomalous scientific data; and to integrate postpositivist, constructivism, and social constructivism to understand the dynamic development model of knowledge of scientific student community. The subjects were science majors of 137 in grade 11 and 127 freshmen. The instruments used in this study included the Knowledge Restructuring Open Test on the method of multidimension clinical exploration and the Cornell Critical Thinking Test (Level X). The major finding of the study was that scientific student community restructed their knowledge with six stages: (1)to question, distinguish, and understand anomalous scientific data;(2)to reflect, judge, and decide the informations from the interaction of subject and object; (3)to use analogical reasoning formulating auxiliary hypotheses based on exemplar, or to use abductive reasoning formulating new hypotheses different to exemplar; (4)to use deduction and induction rationalizing auxiliary hypotheses or new hypotheses; (5)to give a decision for information selection, and formulate an effective community of opinions; (6)to make a weak restructur- ing or radical restructuring according to community of opinions. Based on the results, suggestions were made for future implementation.
