Epistemological beliefs refer to an individual’s thinking and beliefs about the nature of knowledge and knowing. The present study examined two research questions: (1) how do prospective elementary teachers’ epistemological beliefs in science change as a result of instruction specifically designed to improve their epistemological beliefs and (2) what role does the conceptual ecology for epistemological beliefs play in their development? The study was correlational with a sample of 161 prospective elementary teachers (148 female, 13 male). Self-report questionnaires tapping four dimensions of epistemological beliefs (certainty-simplicity, justification, source, attainability of truth) were given to prospective elementary teachers at two time points during an introductory science course. Results indicated that prospective elementary teachers became more sophisticated in their beliefs across all four dimensions of epistemological beliefs. It was found that one component of conceptual ecology for epistemological beliefs, thinking dispositions, was related to the development of epistemological beliefs. Prospective teachers with high thinking dispositions developed more sophisticated beliefs in comparison to prospective teachers with low thinking dispositions.  相似文献

Over the years, research on students’ epistemological beliefs has resulted in a growing common understanding but there are still some major points of discussion. Especially, the lack of consensus on the context-general and/or context-specific nature of epistemological beliefs deserves our attention.We argue that research in the field today is mainly characterized by a top-down approach that investigates students’ domain-specific beliefs from a general epistemological perspective. Alternatively, we report on one of our studies as well as some other research that takes a bottom-up approach starting from students’ domain-specific belief systems and analyzing their epistemic dimensions. Results of these studies point to the highly domain-specific nature of students’ beliefs about knowledge and knowing. Therefore, a conceptual distinction between students’ general epistemological beliefs and the epistemic dimensions of domain-related belief systems is recommended as a more appropriate way to address the context-general–context-specific discussion on epistemological beliefs.  相似文献

This study adopted a cross-sectional and correlational research design in an attempt to add our understanding of student- and teacher-level factors that help explain variability in students’ science achievement to the existing literature. More specifically, the present article examined students’ science achievement in relation to their constructivist learning environment perceptions, epistemological beliefs, and self-regulation as well as their science teachers’ characteristics. Data were gathered from both 137 science teachers and their 3281 seventh grade students via administering self-report questionnaires. Hierarchical linear modeling (HLM) analysis was conducted to analyze the two-level data (student level and teacher level). Students’ learning environment perceptions, epistemological beliefs, achievement goals, and self-regulation constituted student-level data while teachers’ self-efficacy, achievement goals, and epistemological beliefs constituted teacher-level data. The findings indicated that students’ constructivist learning environment perceptions were significant predictors of their science achievement. Additionally, students with sophisticated epistemological beliefs appeared to be more successful in science. Also, performance avoidance goals were negatively related to science achievement. Among teacher-level variables, teachers’ self-efficacy and sophisticated epistemological beliefs were found to be positively linked to students’ science achievement.  相似文献

Student teachers’ research is usually valued more for its contribution to their professional learning than for its contribution to the research topic itself. This paper reports on a research collaboration with eight student primary teachers in England, intended to build on a previously established project investigating young children’s epistemological beliefs. Analysis of the students’ written reports leads to an elaborated conceptual framework that draws attention to the need for a dialogue with all children about the interfaces experienced within, between and beyond each school context. The conclusions point to the distinctive research position held by student teachers in crossing boundaries between school and university contexts, and the particular relevance of the research topic for illuminating the out-of-school knowledge integral to children’s sense of self and learning.  相似文献

We describe the main principles of the framework theory approach to conceptual change and briefly report on the results of a text comprehension study that investigated some of the hypotheses that derive from it. We claim that children construct a naive physics which is based on observation in the context of lay culture and which forms a relatively coherent conceptual system—i.e., a framework theory—that can be used as a basis for explanation and prediction of everyday phenomena. Learning science requires fundamental ontological, epistemological, and representational changes in naive physics. These conceptual changes take a long time to be achieved, giving rise to fragmentation and synthetic conceptions. We also argue that both fragmentation and synthetic conceptions can be explained to result from learners’ attempts assimilate scientific information into their existing but incompatible naive physics.  相似文献

Over the last decade, research related to personal epistemological beliefs has offered insight into how to promote effective teaching and learning across educational settings. Personal epistemological beliefs reflect an individual's views about what knowledge is, how knowledge is gained, and the degree of certainty with which knowledge can be held. However, there has been no research that specifically investigates the relationship between such epistemological beliefs and early childhood practice. This paper draws together current research findings on epistemological beliefs and tertiary learning to provide a conceptual framework which can be used in early childhood teacher education programs to provide a basis for investigating early childhood teachers' understanding about their own learning and how they use this knowledge in their practice.  相似文献

In recent years, there has been an increasing interest among educational researchers in exploring the relationships between learners’ epistemological beliefs and their conceptions of learning. This study was conducted to investigate these relationships particularly in the domain of science. The participants in this study included 407 Taiwanese college science‐major students. All of them responded to two major questionnaires, one assessing their scientific epistemological beliefs (SEBs) and the other one probing their conceptions of learning science (COLS). The SEB questionnaire included four factors: “certainty,” “source,” “development,” and “justification” of science knowledge. The COLS survey consisted of six factors in a hierarchical order, that is, learning science as “memorizing,” “preparing for tests,” “calculating and practicing,” “increasing one’s knowledge,” “application,” and “understanding and seeing in a new way.” The students’ confidence and interest toward learning science were also assessed by additional questionnaire items. Stepwise regression analyses, in general, showed coherence between students’ SEBs and their COLS, indicating that the sophistication of SEBs was consistent with less agreement with lower‐level COLS (such as “memorizing” and “preparing for tests”) as well as more agreement with higher‐level COLS (such as “understanding and seeing in a new way”). However, the SEB’s “justification” factor was positively related to almost all of COLS factors from the lower‐level to higher‐level. This study finally found that among all of the SEB and COLS factors, the “preparing for tests” factor in COLS was the solely significant variable for predicting students’ interest in science and confidence toward learning science.  相似文献

A large body of research in the conceptual change tradition has shown the difficulty of learning fundamental science concepts, yet conceptual change schemes have failed to convincingly demonstrate improvements in supporting significant student learning. Recent work in cognitive science has challenged this purely conceptual view of learning, emphasising the role of language, and the importance of personal and contextual aspects of understanding science. The research described in this paper is designed around the notion that learning involves the recognition and development of students’ representational resources. In particular, we argue that conceptual difficulties with the concept of force are fundamentally representational in nature. This paper describes a classroom sequence in force that focuses on representations and their negotiation, and reports on the effectiveness of this perspective in guiding teaching, and in providing insight into student learning. Classroom sequences involving three teachers were videotaped using a combined focus on the teacher and groups of students. Video analysis software was used to capture the variety of representations used, and sequences of representational negotiation. Stimulated recall interviews were conducted with teachers and students. The paper reports on the nature of the pedagogies developed as part of this representational focus, its effectiveness in supporting student learning, and on the pedagogical and epistemological challenges negotiated by teachers in implementing this approach.  相似文献

This study investigated preservice elementary science teachers’ (PSTs) informal reasoning regarding socioscientific issues (SSI), their epistemological beliefs, and the relationship between informal reasoning and epistemological beliefs. From several SSIs, nuclear power usage was selected for this study. A total of 647 Turkish PSTs enrolled in three large universities in Turkey completed the open-ended questionnaire, which assessed the participants’ informal reasoning about the target SSI, and Schommer’s (1990) Epistemological Questionnaire. The participants’ epistemological beliefs were assessed quantitatively and their informal reasoning was assessed both qualitatively and quantitatively. The findings revealed that PSTs preferred to generate evidence-based arguments rather than intuitive-based arguments; however, they failed to generate quality evidence and present different types of evidence to support their claims. Furthermore, among the reasoning quality indicators, PSTs mostly generated supportive argument construction. Regarding the use of reasoning modes, types of risk arguments and political-oriented arguments emerged as the new reasoning modes. The study demonstrated that the PSTs had different epistemological beliefs in terms of innate ability, omniscient authority, certain knowledge, and quick learning. Correlational analyses revealed that there was a strong negative correlation between the PSTs’ certain knowledge and counterargument construction, and there were negative correlations between the PSTs’ innate ability, certain knowledge, and quick learning dimensions of epistemological beliefs and their total argument construction. This study has implications for both science teacher education and the practice of science education. For example, PST teacher education programs should give sufficient importance to training teachers that are skillful and knowledgeable regarding SSIs. To achieve this, specific SSI-related courses should form part of science teacher education programs.  相似文献

In this study we present the structure and implementation of a model-based inquiry teaching–learning sequence (TLS) integrating expressive, experimental and exploratory modelling pedagogies in a cyclic manner, with the aim of enhancing primary education student teachers’ epistemological beliefs about the aspects, nature, purpose and change of models as well as their conceptual understanding of light phenomena related to properties of optical fibres. The subjects were 16 prospective primary teachers involved in modelling activities, employing both hands-on experiments and computer modelling activities, based on the application of the ray model. Student teachers were tested before and after the implementation of the TLS by semi-structured interviews and a written questionnaire. Results show that before the TLS most students adopted epistemologically naïve realistic beliefs about models, whereas after the TLS there was an overall significant transition from naïve to more sophisticated epistemological beliefs, as well as significant improvements in their conceptual knowledge about light phenomena. Nevertheless, the relation between epistemological beliefs and conceptual understanding seems to be aspect-dependent, so our evidence suggests that more educational effort is required in order to establish a coherent relationship between them.  相似文献

The purpose of this paper is to investigate the impact of problem-based learning (PBL) on freshmen engineering students’ beliefs about physics and physics learning (referred to as epistemological beliefs) and conceptual understanding of physics. The multiple-choice test of energy and momentum concepts and the Colorado learning attitudes about science survey were used to collect the data. The sample consisted of 142 students enrolled in the PBL and traditional lecture classes in the engineering faculty of a state university in Turkey. The analyses showed that the PBL group obtained significantly higher conceptual learning gains than the traditional group and the change (improvement) in the PBL group students’ beliefs from the pre- to post test were significantly larger than that of the traditional group. The results revealed that beliefs were correlated with conceptual understanding. Suggestions are presented regarding the implementation of the PBL approach.  相似文献

This study was conducted to explore the interplay between students’ scientific epistemological beliefs and their perceptions of constructivist learning environments. Through analysing 1,176 Taiwanese tenth-graders’ (16-year-olds) questionnaire responses, this study found that students tended to perceive that actual learning environments were less constructivist orientated than what they preferred. Students having epistemological beliefs more orientated to constructivist views of science (as opposed to empiricist views about science) tended to have a view that actual learning environments did not provide sufficient opportunities for social negotiations (p < 0.01) and prior knowledge integration (p < 0.01); and moreover, they show significantly stronger preferences to learn in the constructivist learning environments where they could (1) interact and negotiate meanings with others (p < 0.001), (2) integrate their prior knowledge and experiences with newly constructed knowledge (p < 0.001) and (3) meaningfully control their learning activities (p < 0.001). The main thrust of the findings drawn from this study indicates that teachers need to be very aware of students’ epistemological orientation towards scientific knowledge, and to complement these preferences when designing learning experiences, especially to provide constructivist-based lessons to enhance science learning for students who are epistemologically constructivist orientated.  相似文献

Compared with research on the role of student engagement with expert representations in learning science, investigation of the use and theoretical justification of student-generated representations to learn science is less common. In this paper, we present a framework that aims to integrate three perspectives to explain how and why representational construction supports learning in science. The first or semiotic perspective focuses on student use of particular features of symbolic and material tools to make meanings in science. The second or epistemic perspective focuses on how this representational construction relates to the broader picture of knowledge-building practices of inquiry in this disciplinary field, and the third or epistemological perspective focuses on how and what students can know through engaging in the challenge of representing causal accounts through these semiotic tools. We argue that each perspective entails productive constraints on students’ meaning-making as they construct and interpret their own representations. Our framework seeks to take into account the interplay of diverse cultural and cognitive resources students use in these meaning-making processes. We outline the basis for this framework before illustrating its explanatory value through a sequence of lessons on the topic of evaporation.  相似文献

In this article we problematize the purpose of teaching science in preschool and the competences preschool teachers need in order to conduct science activities in the classroom. The empirical data were collected through an action research project with five preschool and primary school teachers (K-6). In the first section of this paper we use one situation, a floating–sinking experiment, as an illustration of how two different epistemological perspectives generate different foci on which kind of science teaching competences can be fruitful in preschool settings. In the first perspective, the central goal of science teaching is the development of the children’s conceptual understanding. With this perspective, we found that the science activities with children were unsuccessful, because their thoughts about concepts did not develop as expected, the situation even enhanced a “misconception” concerning density. Moreover, the teacher was unsuccessful in supporting the children’s conceptual learning. The second perspective uses a feminist approach that scrutinizes science, where we investigate if the floating–sinking activity contributes to a feeling of participation in a scientific context for the children and if so how the teacher promotes this inclusion. This second perspective showed that the children’s scientific proficiency benefited from the situation; they had a positive experience with density which was reinforced by the teacher. The children discovered that they had power over their own learning by using an experimental approach. On the basis of these findings, we conclude that there are competences other than subject matter knowledge that are also important when preschool teachers engage children in scientific activities. Through process-oriented work with the teacher group, we identified four concrete skills: paying attention to and using children’s previous experiences; capturing unexpected things that happen at the moment they occur; asking questions that challenge the children and that stimulate further investigation; creating a situated presence, that is, “remaining” in the situation and listening to the children and their explanations. We discuss possible ways to move preschool teachers away from their feelings of inadequacy and poor self-confidence in teaching science by reinforcing this kind of pedagogical content knowledge.  相似文献

This study examined elementary school children's beliefs about learning and assessed the influences of such beliefs on their understanding of science texts. Eighty-three children, 46 from Grade 4 and 37 from Grade 6, were administered a questionnaire on children's implicit notions of learning. Children were also asked to read a science text and complete several tasks that assessed their understanding of text information. Results indicated that older children were more likely to hold constructivist views of learning, and they also performed better than younger children on the text-processing tasks. As well, children's views of learning were significantly related to depth of text understanding when age effects were controlled. This study extends current research on epistemological beliefs of university and high school students. Implications of children's beliefs about learning and their roles in knowledge construction are discussed. Copyright 2001 Academic Press.  相似文献

One focus of classroom based research in recent years has been the exploration of the relationships between teachers’ personal beliefs about the teaching/learning process and their classroom practice, and, in the context of science education, between teachers’ epistemological beliefs and classroom actions. This paper, based on two case studies of classroom practice, examines the beliefs and actions of two high school science teachers in relation to their involvement in a curriculum development exercise which was being undertaken by the Children's Learning in Science Project (now the Children's Learning in Science Research Group) based at the University of Leeds, UK.  相似文献

Relationships between students’ perceptions and their non-cognitive outcomes (epistemological beliefs, self-efficacy and attitudes to science) were investigated through secondary analysis of data from 14,167 United Arab Emirates students who participated in the Programme for International Student Assessment (PISA). Structural equation modeling (SEM) suggested that students’ perceptions of the learning environment were related to the non-cognitive outcomes of epistemological beliefs, self-efficacy and attitudes. Also, epistemological beliefs were found to have a statistically-significant and positive relationship with self-efficacy and attitudes, and self-efficacy was significantly related to attitudes.

There has been extensive research on children’s understanding of evaporation, but representational issues entailed in this understanding have not been investigated in depth. This study explored three students’ engagement with science concepts relating to evaporation through various representational modes, such as diagrams, verbal accounts, gestures, and captioned drawings. This engagement entailed students (a) clarifying their thinking through exploring representational resources; (b) developing understanding of what these representations signify; and (c) learning how to construct representational aspects of scientific explanation. The study involved a sequence of classroom lessons on evaporation and structured interviews with nine children, and found that a focus on representational challenges provided fresh insights into the conceptual task involved in learning science. The findings suggest that teacher‐mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students; and (b) enhanced teacher insights into students’ thinking.  相似文献
