This research involved na?ve physics learners who were interested in majoring in science or engineering. In a semester-long
quasi-experimental study, open-ended pretests and weekly interviews were used to analyse the progressive development of students’
conceptions relating to sound and wave motion. Semi-structured interviews were also conducted to elucidate: (1) how their
conceptions developed from everyday conceptions to unclear scientific conceptions to scientific conceptions, and (2) their
beliefs of physics knowledge. Despite efforts to enable these students to learn physics, the findings showed that only two
out of ten students developed acceptable physics conceptions during the course that would enable them to pursue the subject
to a higher level. Also, students’ conceptual development was found to be related to their cognitive understanding and to
epistemological beliefs of physics. Therefore, to facilitate na?ve physics learners’ success in a general physics course,
in addition to the acquisition of content knowledge, explicit emphasis needs to be placed on the nature of physics knowledge. 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

Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively.Purpose: The purpose of this study is to explore the relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students’ data were used.Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used.Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics.Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics. 相似文献

This study investigated the relationship between epistemological beliefs, prior domain knowledge and self-regulated learning. Biology students (n?=?25) and humanities students (n?=?26) who varied in their epistemological beliefs learned with a hierarchical hypertext about the topic of genetic fingerprinting. During their learning processes, logfiles and questionnaire data were collected. Results indicate that students do metacognitively calibrate their learning process to the complexity of the presented learning material, e.g. by processing more complex deeper-level nodes longer. Furthermore, these calibration processes were significantly related to epistemological beliefs. For example, more ‘sophisticated’ epistemological beliefs were associated with processing more nodes, whereas more ‘naïve’ beliefs were related to spending more time on single nodes. Both effects were especially pronounced on deeper hierarchical hypertext levels. Prior domain knowledge also had an impact, especially on comprehensibility ratings: biology students considered all nodes more comprehensible than humanities students. Additionally, epistemological beliefs as well as prior domain knowledge were also significantly associated with the learning outcome: for example, more prior domain knowledge led to significantly higher learning outcome. 相似文献

This study explored the domain specificity of students' beliefs about academic knowledge in three related studies. Using a four-factor model as an initial framework, a series of domain-specific items about mathematics and history was developed. In Study I, these items were administered to 182 undergraduates, and the psychometric properties and underlying factor structure were examined via exploratory factor analysis. In Study II, the modified instrument, the Domain-Specific Beliefs Questionnaire (DSBQ), was administered to 633 students and a confirmatory factor analysis was conducted. A subsample of participants' responses on the DSBQ was also compared to responses on Schommer's epistemological questionnaire. Study III involved a second confirmatory factor analysis using data from a new sample (n = 523). Those data were examined for potential gender differences. Overall, the results of this investigation suggested that students possess certain domain-specific beliefs about knowledge in mathematics and history. Further, a significant moderate relationship between the DSBQ and Schommer's questionnaire provided some evidence of domain-generality in undergraduates' epistemological beliefs. 相似文献

本研究采用整群抽样法抽取三年级师范生133名,运用ST—IAT方法探讨他们内隐的个体认识信念。研究发现,师范生内隐个体认识信念未表现出显著的建构主义取向。教师教育理论知识对其内隐个体认识信念影响较小,而学科的影响较大,文科师范生认为知识是离散的,知识来自个人探索。相对男性而言,女性师范生内隐个体认识信念更倾向于知识是离散的,知识来自个人探索,学习是快速的,学习是不可控的。 相似文献

This study investigated the effects of problem-based learning on students’ beliefs about physics and physics learning and
conceptual understanding of Newtonian mechanics. The study further examines the relationship between students’ beliefs about
physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish university students (PBL = 55,
traditional = 69) enrolled in a calculus-based introductory physics class. Students’ beliefs about physics and physics learning
and their physics conceptual understanding were measured with the Colorado Learning Attitudes about Science Survey (CLASS)
and the Force Concept Inventory (FCI), respectively. Repeated measures analysis of variance of how PBL influence beliefs and
conceptual understanding were performed. The PBL group showed significantly higher conceptual learning gains in FCI than the
traditional group. PBL approach showed no influence on students’ beliefs about physics; both groups displayed similar beliefs.
A significant positive correlation was found between beliefs and conceptual understanding. Students with more expert-like
beliefs at the beginning of the semester were more likely to obtain higher conceptual understanding scores at the end of the
semester. Suggestions are presented regarding the implementation of the PBL approach. 相似文献

This study investigated the effect of metaconceptual teaching interventions on students’ understanding of force and motion
concepts. A multimethod research design including quasi-experimental design and case study designs was employed to compare
the effect of the metaconceptual activities and traditional instruction and investigate students’ reactions to metaconceptual
teaching interventions. The participants (45 high school students in the USA) were enrolled in one of the two physics classes
instructed by the same science teacher. In the experimental group, students’ engagement in metaconceptual knowledge and processes
was facilitated through various instructional activities, including poster drawing, journal writing, group debate, concept
mapping, and class and group discussions. These activities were intended to facilitate students’ engagement in (a) becoming
aware of their existing and past conceptions, associated beliefs, everyday experiences, and contextual differences, (b) monitoring
their understanding of the new conception, the changes in ideas, and the consistency between existing and new conceptions,
and (c) evaluating the relative ability of competing conceptions to explain a physical phenomenon. In the comparison group,
the same content knowledge was explained by the teacher along with the use of laboratory experiments, demonstrations, and
quantitative problem solving. Students’ reactions to the designed instructional activities indicated that metaconceptual teaching
interventions were successful in facilitating students’ engagement in several types of metaconceptual functioning. The results
showed that students in the experimental group had significantly better conceptual understanding than their counterparts in
the comparison group and this positive impact remained after a period of 9 weeks. 相似文献

The purposes of the study were to assess preservice teachers’ domain-specific epistemological beliefs and to investigate whether preservice teachers distinguish disciplinary differences (physics, chemistry, and biology) in domain-specific epistemological beliefs. Mixed-method research design guided the present research. The researcher explored three epistemological dimensions: certainty and simplicity of knowledge, justification for knowing, and source of knowledge. Both quantitative and qualitative results suggested that a domain-specific epistemological beliefs system is a valid model to describe preservice teachers’ epistemological beliefs. In terms of epistemological beliefs, disciplinary differences in physics, chemistry, and biology were discussed in the last parts of the study. 相似文献

This study investigates how scaffolding type and learners’ epistemological beliefs influence ill-structured problem solving. The independent variables in this study include the type of scaffolding (task-supported, self-monitoring) and the student's epistemological belief level (more advanced, less advanced). The dependent variables include three components of problem-solving skill (problem representation, solution development, monitoring and evaluation). The two-way multivariate analysis of variance results reveal that students in the self-monitoring scaffolding group earned higher scores on problem representation and solution development than those in the task-supported scaffolding group. Students with more advanced epistemological beliefs also earned higher scores on solution development and monitoring and evaluation than did those with less advanced epistemological beliefs. In addition, a significant interaction was found between scaffolding type and epistemological belief level. These findings suggest that students can benefit from self-monitoring scaffolding in web-based problem solving and that different types of scaffolding should be provided according to the student's epistemological belief level. 相似文献

Education literature suggests that preservice teachers hold similar initial beliefs, viewing the teacher as the authority figure passing knowledge to the students. In consistency with constructivist practice, these beliefs should be challenged to enable the preservice teachers to develop alternative ideas, seeing the students capable of constructing knowledge with the help of the teacher. These beliefs are found difficult to change in the course environment. Drawing on surveys and teaching observations from four preservice teachers in an introduction methods course, the study showed that the four participants had different epistemological beliefs, some beliefs being more resistant to change than others. 相似文献

We examined the intersection of students' understanding and acceptance of evolution and their epistemological beliefs and cognitive dispositions. Based on previous research, we hypothesized there would be a relation between understanding and acceptance. We also hypothesized that students who viewed knowledge as changing and who have a disposition toward open‐minded thinking would be more likely to accept the scientific explanation of human evolution, and that beliefs and dispositions would not be related to acceptance of a topic that is generally perceived as noncontroversial. Ninety‐three undergraduate students enrolled in a nonmajors biology class completed measures of their (a) content knowledge of evolution and photosynthesis and respiration; (b) acceptance of theories of animal evolution, human evolution, and photosynthesis; and (c) epistemological beliefs and cognitive dispositions. Although our findings did reveal a significant relation between knowledge and reported acceptance for photosynthesis, there was no relation between knowledge and acceptance of animal or human evolution. Epistemological beliefs were related to acceptance, but only to the acceptance of human evolution. There was no relation between students' epistemological beliefs and their general acceptance of animal evolution or photosynthesis. Three subscales, Ambiguous Information, Actively Open‐Minded Thinking, and Belief Identification, were significantly correlated with understanding evolutionary theory. We argue these findings underscore the importance of intentional level constructs, such as epistemological beliefs and cognitive dispositions, in the learning of potentially controversial topics. © 2003 Wiley Periodicals, Inc.

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

The uneven distribution of knowledge within modern societies requires a reliance on sources (e.g., reference books, teachers,
the Internet) in addition to own experience. Most scientific issues are far too complex to be understood in any depth by laypersons.
Successful knowledge acquisition comprises the ability to vary the amount of sources used and to appreciate different sources
in different contexts. Epistemological beliefs (i.e., learners’ beliefs on the nature of knowledge and knowing) might affect
this task. We report research on secondary school students’ decisions about the amount of sources they would use and their
source appreciation (the perceived usefulness of several sources), the impact of epistemological beliefs on such decisions,
and their adaptivity to the contextual circumstances of the information search. After exposure to an experimentally induced
epistemological sensitization, the students provided information on how they would proceed to confirm given knowledge. Study
1 explored the amount of sources (source quantity and access approaches). Study 2 investigated the perceived usefulness of
several sources (source appreciation). Results showed an increase in the amount and appreciation of sources in a high-involving
context and after sophisticated sensitization. More sophisticated beliefs led to a larger increase in the amount of sources
in a high-involving context. Furthermore, epistemological beliefs predicted the difference in source appreciation between
contexts. Conclusions are drawn for the use of sensitization and the teaching of digital literacy in schools. 相似文献

To obtain a more complete understanding of personal epistemology this study examines two epistemic paradigms – ways of knowing (specifically connected knowing and separate knowing) and epistemological beliefs (specifically beliefs about knowledge structure, knowledge stability, learning speed, and learning ability). Participants were 107 college students who completed questionnaires that assessed ways of knowing and epistemological beliefs. Multivariate analysis of variance revealed that men score significantly higher on separate knowing. Path analyses revealed that the effects of ways of knowing on academic performance are mediated by belief in the speed of learning. 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

How do epistemological attitudes and beliefs influence learning from text? We conceptualize epistemological attitudes and
beliefs as components of metacognitive knowledge. As such, they serve an important function in regulating the use of epistemic
strategies such as knowledge-based validation of information and checking arguments for internal consistency. We report results
from two studies that investigated the effects epistemological attitudes and beliefs on the use of epistemic strategies in
academic learning and the motivational states that mediate these effects. Study 1 (N = 289) tested a mediation model with epistemological attitudes (separate vs. connected knowing) and textual characteristics
as distal predictors, and learning goals (learning factual knowledge vs. developing an own standpoint) as mediator variables.
Separate knowing had large indirect effects on the use of epistemic strategies via the goal to develop an own point of view.
In addition, learners adapted their learning goals and epistemic strategies depending on objective characteristics and the
perceived familiarity of the texts they read. In Study 2 (N = 124), epistemological beliefs concerning the uncertainty of knowledge increased the use of epistemic strategies only when
extrinsic study motivation was low. A mediated moderation model established this effect to be mediated by specific epistemic
curiosity. These results illuminate the mechanisms of how epistemological attitudes and beliefs affect self-regulated learning.
In contrast to other types of learning strategies, the use of epistemic strategies seems to be strongly and consistently linked
to epistemological attitudes and beliefs. 相似文献

We examine the relationship between high school students' beliefs about the nature of knowledge, or epistemological beliefs, and their attitudes toward education. High school students completed an epistemological questionnaire assessing their beliefs in fixed ability to learn, simple knowledge, quick learning, and certain knowledge. Then they answered open-ended questions on a hypothetical character named Billy. They were to advise Billy if he should go on to college even though his grades were poor and his parents had no money. Finally, they completed questions about their own feelings toward high school and their expectations of the demands of college. Attitudes toward school were then regressed on epistemological belief factor scores. The less students believed in fixed ability to learn and quick learning, the more likely they were to encourage Billy to go to college and to appreciate the role of school in furthering their education, gaining employment, and living everyday life. 相似文献
