Refutation text is potentially more effective than standard text for conceptual change. Learning from text and graphic is also potentially superior to learning from text alone. In two studies, we investigated the effectiveness of both a refutation text and a refutation graphic for promoting high school students’ conceptual change learning about season change, as well as their metacognitive awareness of conceptual conflict and knowledge revision. In both studies, participants were randomly assigned to one of four conditions: (1) standard text with standard graphic, (2) standard text with refutation graphic, (3) refutation text with standard graphic, or (4) refutation text with refutation graphic. Both studies had a pretest, immediate post-test, and delayed post-test design and involved students with an initial common misconception about the causes of season change. In Study 2, explicit relevance instructions to observe the important illustration were given to the participants. In both studies, refutation text with refutation graphic was not more beneficial than other instructional materials, either at immediate or delayed post-test. In Study 1, more stable conceptual change learning emerged in readers of the refutation text with standard graphic compared to readers in the control condition. In Study 2, readers of the standard text with refutation graphic performed as well as readers of the refutation text with standard graphic. In addition, more readers of the refutation text with either graphic showed metacognitive awareness of their knowledge change compared to readers in the control condition. Educational implications underline the importance of relevance instructions for guiding readers toward the graphic and of the design of text-graphic pairing to sustain knowledge revision.  相似文献

This paper provides a critical commentary on a suite of eight papers, which focus on conceptual change research in science education. Responses by Mercer, Smardon and Wells to a paper by Treagust and Duit are observed to reflect the backgrounds of the three authors with Wells focusing on issues of ontology and the affective domain. Mercer and Smardon focus on issues of identity and the role of dialog. Hewson’s, Vosniadou’s and Tiberghien’s responses to Roth, Lee and Hwang offer robust critique of what appear to be exploratory ideas. To what extent the authors of the response papers enter into dialog with the papers is discussed. How far research into learning in science has progressed since the 1980s is examined.

This article argues that the analogy between conceptual changes in the history of science and conceptual changes in the development of young children is problematic. We show that the notions of ‘conceptual change’ in Kuhn and Piaget’s projects, the two thinkers whose work is most commonly drawn upon to support this analogy, are not compatible in the sense usually claimed. We contend that Kuhn’s work pertains not so much to the psychology of individual scientists, but to the way philosophers and historians should describe developments in communities of scientists. Furthermore, we argue that the analogy is based on a misunderstanding of the nature of science and the relation between science and common sense. The distinctiveness of the two notions of conceptual change has implications for science education research, since it raises serious questions about the relevance of Kuhn’s remarks for the study of pedagogical issues.  相似文献

We investigated whether problem-based learning (PBL) can foster conceptual change. Students were randomly assigned to a PBL, lecture-based, or self-study group, all receiving instruction about the topic of Newtonian laws. Conceptual change was measured from pre- to immediate post-test (directly after instruction) and from immediate post-test to delayed post-test after one week. Results showed that the PBL-group outperformed both the lecture and the self-study group on the immediate post-test. This result supported the hypothesis that PBL can increase the likelihood of conceptual change. The PBL group also outperformed both other groups at the delayed post-test after one week; the decline in conceptual change from immediate to delayed post-test was similar for all three groups. Findings are discussed in terms of cognitive engagement.  相似文献

We engage in a metalogue based on eight papers in this issue of Cultural Studies of Science Education that review the state of conceptual change research and its possible affect on the teaching and learning of science. Our discussion addresses three aspects of conceptual change research: theoretical, methodological, and practical, as we discuss conceptual change research in light of our experiences as science educators. Finally, we examine the implications of conceptual change research for the teachers and students with whom we work.

The frequently encountered problems of students being unable to utilize schoollearned science in different contexts, and of students forgetting what they have learned in a short time after initial instruction, are two important problems for classroom practitioners. This paper advocates a shift in focus of conceptual change learning research in order to address these problems. It draws upon four overlapping areas: conceptual change learning is the broad subject area that sets the epistemological background; transfer and durability of scientific conceptions are the two problem areas under scrutiny, while metacognition is seen as potential mediator of improvement. The paper offers a brief review of existing literature on the four areas; it proposes confronting the two problems by incorporating metacognitive instruction in the learning environment of primary school science; and it reports on recently completed research.  相似文献

This paper presents a model of how children generate concrete concepts from perception through processes of differentiation and integration. The model informs the design of a novel methodology (evolutionary maps or emaps), whose implementation on certain domains unfolds the web of itineraries that children may follow in the construction of concrete conceptual knowledge and pinpoints, for each conception, the architecture of the conceptual change that leads to the scientific concept. Remarkably, the generative character of its syntax yields conceptions that, if unknown, amount to predictions that can be tested experimentally. Its application to the diurnal cycle (including the sun's trajectory in the sky) indicates that the model is correct and the methodology works (in some domains). Specifically, said emap predicts a number of exotic trajectories of the sun in the sky that, in the experimental work, were drawn spontaneously both on paper and a dome. Additionally, the application of the emaps theoretical framework in clinical interviews has provided new insight into other cognitive processes. The field of validity of the methodology and its possible applications to science education are discussed.  相似文献

This article presents a metalogue discussion about the two focus articles and the six associated review essays on the topic of conceptual change as it applies to research, and science teaching and learning in museum settings. Through the lenses of a sociocultural perspectives of learning we examine the applicability of the ideas presented in the forum for museums and museum educators. First we reflect on the role that emotions can play in concept development; second, we reflect on the role of language, talk, and gestures to concept development and conceptual change in the short-lived nature of experiences and conversations in museums; and third, we consider the nature of objects as representations of science content in museum settings.

This study explored the relationship between task values, engagement, and conceptual change. One hundred and sixty-six under graduate students were randomly assigned to one of three task value instructional inductions (utility, attainment, and control) to determine whether induced task values would result in different degrees of engagement and conceptual change when reading a refutation text about the common cold. It was hypothesized that the participants in the utility, attainment, and control conditions would differ in their engagement, and degree of conceptual change.  相似文献

A structural equation model of conceptual change in physics   总被引:1,自引:0,他引:1  
A model of conceptual change in physics was tested on introductory‐level, college physics students. Structural equation modeling was used to test hypothesized relationships among variables linked to conceptual change in physics including an approach goal orientation, need for cognition, motivation, and course grade. Conceptual change in physics was determined using gains from pre‐ to post‐administration of the Force Concept Inventory (FCI). Results indicated that need for cognition and approach goals had a significant influence on motivation. Motivation influenced change scores on the FCI both directly, and indirectly, through course grade. Finally, course grade directly influenced conceptual change. The implications of these findings for future research and developing students' conceptual change in physics are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 901–918, 2011  相似文献

This quasi‐experimental study investigated the effects on 558 grades five and six students of three different teaching conditions: the classical model of conceptual change (for which cognitive conflict is considered as a precondition to the transformation of knowledge), the prevalence model of conceptual change (in which different conceptions can coexist, with one of them surpassing the others), and repetition of traditional teaching (that avoids cognitive conflicts and concentrates on the automatization of appropriate thought processes). These conditions were reduced to sequencing considerations, as classical model participants were first subjected to a possible cognitive conflict induced by a video, followed by another video about the targeted conceptions; prevalence model participants were subjected to the same videos but in the opposite chronological order; and repetition condition participants watched the “traditional teaching” video twice. Differences in accuracy and response times between our computerized and validated “sink/float” pretest and retest were analyzed. Results and interpretations confirm that cognitive conflicts are useful in teaching sequences that aim at producing conceptual changes. However, the major findings of this research suggest that such conflicts should not necessarily be triggered at the very beginning of teaching sequences, and therefore that the prevalence model might possibly be the preferable one to promote conceptual changes in real‐life school science teaching settings. Recommendations for teaching and research are formulated. Presented results, although statistically significant, sometimes show weak effects sizes, and therefore call for further research efforts. © 2015 Wiley Periodicals, Inc. J Res Sci Teach 52: 1082–1108, 2015. Cette recherche étudie l'effet de trois conditions expérimentales sur des élèves de 5e et 6e années du primaire: le modèle classique du changement conceptuel (selon lequel le conflit cognitif est considéré comme préalable à une transformation des connaissances), le modèle de prévalence conceptuelle (selon lequel différentes conceptions peuvent coexister, avec l'une d'elle qui prévaut sur les autres) et la répétition simple de l'enseignement (qui néglige de produire des conflits cognitifs et se concentre sur l'automatisation des procédés et informations qui mènent aux bonnes réponses). Ces conditions ont été réduites à des considérations de séquençage. Ainsi, les sujets de la condition classique ont d'abord été exposés à des informations présentées par vidéo et susceptible de produire un conflit cognitif, suivi par une autre vidéo présentant les conceptions scientifiques désirées; les sujets de la condition prévalence ont écouté les deux mêmes vidéos mais dans l'ordre inverse; et les sujets de la condition répétition ont vu deux fois la vidéo des conceptions scientifiques. Une analyse comparative des gains d'exactitude et de temps de réaction lors d'une tâche portant sur la flottabilité des corps a été effectuée. Les résultats et l'interprétation tendent à confirmer que les conflits cognitifs sont nécessaires aux changements conceptuels. Cependant, les résultats suggèrent également que les conflits n'ont pas nécessairement avantage à être provoqués en début de séquence et conséquemment que le modèle de prévalence serait possiblement celui qui aurait avantage à être utilisé en classe de science. Des recommandations pédagogiques sont formulées. Malgré des résultats clairement significatifs, les faibles magnitudes d'effets obtenues pour certaines mesures appellent à la prudence et à la poursuite des travaux.  相似文献

This study explored how confidence in prior knowledge, self-efficacy, interest, and prior knowledge interact in conceptual change learning. One hundred and sixteen college students completed an assessment of confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions before reading a refutation text on seasonal change. Students’ misconceptions and scientific understanding of seasonal change was then assessed before and after reading a refutation text, and again at a two week delayed posttest. Three profiles of students emerged based on their confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions. The profiles included: (1) Low (low confidence, self-efficacy, interest, and prior scientific understanding and high prior misconceptions), (2) mixed (high confidence, self-efficacy, and interest, but low prior scientific understanding and high prior misconceptions), and (3) high (high confidence, self-efficacy, interest, and prior scientific understanding and low prior misconceptions). Results indicated that the mixed profile appeared to be most productive for conceptual change and that learner characteristics most productive for conceptual change learning may differ from those most productive in other learning situations.  相似文献

Research indicates that teachers’ conceptions of and approaches to teaching with technology are central for the successful imple-mentation of educational technologies in higher education. This study advances this premise. We present a 10-year longitudinal study examining teachers’ conceptions of and approaches to teaching and learning with technology. Nine teachers on an online Bachelor of Science in Pharmacy and a Master of Pharmacy programme at a Swedish university were studied using a phenomenographic approach. Results showed clear differences between novice and experienced teachers. Although novice teachers initially held more teacher-focused conceptions, they demonstrated greater and more rapid change than experienced colleagues. Experienced teachers tended to exhibit little to no change in conceptions. Supporting conceptual change should, therefore, be a central component of professional development activities if a more effective use of educational technology is to be achieved.  相似文献

In this response, we attempt to clarify our position on conceptual change, state our position on mental models being a viable construct to represent learning, indicate important issues from the social cultural perspective that can inform our work on conceptual change and lastly comment on issues that we consider to be straw men. Above all we argue that there is no best theory of teaching and learning and argue for a multiple perspective approach to understanding science teaching and learning.

The purpose of this preregistered study was to test an online intervention that presents participants with novel numbers about climate change after they estimate those numbers. An experimental study design was used to investigate the impact of the intervention on undergraduate students’ climate change understanding and perceptions that human caused climate change is plausible. Findings revealed that posttest climate change knowledge and plausibility perceptions were higher among those randomly assigned to use the intervention compared with those assigned to a control condition, and that supplementing this experience with numeracy instruction was linked with the use of more explicit estimation strategies and greater learning gains for people with adaptive epistemic dispositions. Findings from this study replicate and extend prior research, support the idea that novel data can support knowledge revision, identify estimation strategies used in this context, and offer an open-source online intervention for sharing surprising data with students and teachers.  相似文献

This study examined the mental models of the desert environment held by fourth‐ and seventh‐grade students in the USA and whether those mental models could be affected by: (1) classroom field trips to a desert riparian preserve, and (2) interaction with family members at the same preserve. Results generally indicated that students in this study were resolute in their models and that field trips did not impact the types of models students adhered to. Twenty‐three seventh‐grade students who self‐selected to participate in a Family Science Club with their parents did demonstrate a shift in their mental models and developed significantly more sophisticated models over time. A critical implication of the study is that unless transformation of mental models of the environment is an explicit goal of instruction, simple exposure to the environment (even within the context of life science instruction) will not transform understandings of how organisms within an environment act and interact interdependently.  相似文献

The purpose of this study was to investigate the role of epistemic beliefs and knowledge representations in cognitive and metacognitive processing when learning about physics concepts through text. Specifically, we manipulated the representation of physics concepts in texts about Newtonian mechanics and explored how these texts interacted with individuals’ epistemic beliefs to facilitate or constrain learning. Results revealed that when individuals’ epistemic beliefs were consistent with the knowledge representations in their assigned texts, they performed better on various measures of learning (use of processing strategies, text recall, and changes in misconceptions) than when their epistemic beliefs were inconsistent with the knowledge representations. These results have implications for how researchers conceptualize epistemic beliefs and support contemporary views regarding the context sensitivity of individuals’ epistemic beliefs.  相似文献
