This study aims to identify what kind of epistemological resources were activated in unproductive and productive practice by students participating in scientific argumentation, and to explore which contexts result in changes in argumentative practice. We collected transcriptions of participants' argumentative lessons and interview, participants' work sheets, and researchers' field notes. The analysis revealed that the focus group activated different kinds of epistemological resources depending on their practice; propagated, belief, and accumulation in unproductive practice and constructed, understanding, accumulation, formation and rebuttal in productive practice. We found two contextual cues that led to these changes; unfamiliar form of argumentative task was provided and emotional, epistemic, and conceptual support of the epistemic authority. This work can be provided as additional case studies to analyze changes in practice according to learner context-dependent epistemology, and we expect to contribute to discussions of productive epistemology and stabilization for students' authentic science engagement.

In the study, epistemological beliefs, metacognition, and scientific inquiry skills all directly affected the science academic achievement levels of high school students. Also, epistemological beliefs indirectly affected science academic achievement mediated by scientific inquiry skills and metacognition, while metacognition had an indirect effect on science academic achievement level mediated by scientific inquiry skills. We found that scientific inquiry skills had the biggest direct effect, while epistemological beliefs showed the most robust indirect effect on academic achievement level. Thus, we argue that students' scientific inquiry skills should be nurtured for the advancement of their academic achievement. In addition, more careful scholarly attention must be given to both epistemological beliefs and metacognition, which directly and indirectly affected academic achievement level. We believe that epistemological beliefs, metacognition, and scientific inquiry skills should all be considered in an integrative manner when developing educational programs and strategies.

This study investigated preservice teachers' understandings of the ontology and epistemology underlying constructivist notions of teaming. Throughout this study, the epistemological, ontological, and pedagogical characteristics for each teacher's developing views of learning were identified through four in-depth interviews. Data from interviews were used to create three profiles containing ontological beliefs, epistemological commitments and pedagogical beliefs. This study has demonstrated that the notion of a constructivist profile change has significant potential for informing the analysis and description of preservice teachers' beliefs changes. Major findings include: constructivist profile changes overtime, diversification of profile components over time, features of the teachers' pedagogical belief profile changes, and teachers' unawareness of their profiles. However, changes in ontological beliefs and epistemological commitments were not easy, nor were they easily internalized for these teachers. The implications of this research are that preservice teachers should be aware of coexisting different categories of their learning-to-teach profiles, and that teacher educators should provide these preservice teachers with instruction designed to change preservice teachers' profiles towards increasing constructivist views of teaching and learning and restricting other undesirable categories.

The purpose of this study is on the Shera's sociological aspect of librarianship. Jesse H. Shera, educator, philosopher, and theoretician, considered that perhaps his most significant contribution to librarianship was not a “thing” but a “concept”. Library was created to meet certain social necessities, and that its development is closely related not only to intellectual history but also to change in the organizational structure and the value system of its supporting culture. It is axiomatic, then, that the library as a social instrumentality. is, as it has always been, conditioned and shaped by the social milieu within which it function. Therefore we are concerned with the need for a new epistemological discipline, a body of new about knowledge itself.

The most difficult problem for mathematical Platonism is the epistemological problem raised by Paul Benacerraf and Hartley Field. Recently, Mark Balaguer argued that his version of mathematical Platonism, Full Blooded Plantonism (FBP), can solve the epistemological problem. In this paper, I show that there are serious problems with Balaguer's argument. First, I analyse Balaguer's argument and reveal a formal defect in his argument. Then I raise an objection based on an analogical argument. Finally, I disarm some potential moves from Balaguer.

This study considers the experiment of Inhelder and Piaget(1963) in various aspects, and reveals the characteristics of the 'the formation of a critical mind', 'the transformation into the research question', 'the translation into the experiment', and 'the interpretation of the result of the experiment' in Piaget's genetic epistemology. According to these analyses, this study discusses the educational implications that the results of the Piaget's experiment support the education which raises the student's awareness.

Science teachers need to understand what science is, how students learn, how to teach science effectively, and the rationale for their teaching methods. Along this line, this article discusses constructivist learning theory as an alternative to the traditional pedagogy and the origin of various versions of constructivism. Constructivism is defined and used in a variety of contexts including philosophical constructivism, constructivist research paradigm, sociological constructivism, and educational constructivism. Educational constructivism (or psychological constructivism) can be divided into three distinct versions (i.e., individual, radical, and social constructivism) depending on unique ontological and epistemological beliefs that underlie each version. Each version of educational constructivism supports different conceptions of science teaching and learning that are consistent with its specific ontological and epistemological beliefs. In this article, the main tenets of each version of educational constructivism are examined with regard to ontological beliefs, epistemological commitments, and pedagogical beliefs. In addition, two major criticisms on constructivist pedagogy as well as implications for research methods for each version are also discussed.

The purpose of this study was to analyze epistemological beliefs in science as perceived by elementary school students and to examine the purpose of science, the nature of scientific knowledge, the source of scientific knowledge, and the role of experimentation. The subjects of this study were 99 elementary school students. As a tool for examining epistemological beliefs in science, we used adapted questionnaires comprising elements constituting epistemological beliefs, as proposed by Elder (1999). The results of the analysis are as follows: First, in terms of the purpose of science, sixth graders had the most modern beliefs compared to other grades. Second, a statistical significance was found between fourth graders and students in other grades based on the analysis of the nature of scientific knowledge. Third, there was no significant difference in each grade's beliefs concerning the source of scientific knowledge or the role of the experiment.

This study was to explore epistemological features presented in texts of exhibit panels in the science museum located in Gyeonggi Province. Out-of-school or daily experiences allow more properly and potentially students to form informative science image, because the understandings of scientific epistemology were constructed tacitly through various experiences over a long period of time. The target for this study was panel texts of exhibits in a science museum as an of out-of-school context. The analytical framework was adopted from epistemological frameworks by Ryder et al. (1999). The research results were explored in the categories of relationship between scientific knowledge claims and the data, the nature of lines of scientific enquiry, and social dimension of science. It revealed that one exhibit might reflect the characteristics of one epistemological position: relating one data to one knowledge claim; generating knowledge claim from scientists' individual interests or from discipline's internal epistemology; scientists working as a community or an institution. Findings suggested that the exhibits of a science museum including panel texts and medium need to reflect the wide ranges of scientific epistemology.
