Conflict within dyadic interactions as a stimulant for conceptual change in physics

Research suggests that conventional teaching techniques have proved largely ineffective for dealing with the problem of science students’ misconceptions or alternative frameworks. This paper reports an investigation whereby inter‐personal conflict within dyadic interactions is used as a strategy for promoting development towards correct scientific conceptions in specific areas of electrical circuits and mechanics amongst first‐year tertiary physics students. The data indicate that a large number of physics students at the tertiary level hold non‐scientific conceptions of these physical phenomena. The dyadic interaction strategy proved effective as a means of encouraging students to actively and closely consider their own thinking about basic physical concepts. Further, results highlight the importance of inter‐personal conflict in the process of conceptual change.     

Learning scientific concepts through material and social activities: Conversational analysis meets conceptual change

The number of analyses of cognitive activity situated in a material and social world has increased. It has been particularly challenging to the theoretician and researcher to make the bridge from macrosocial theories of cultural learning to microanalytic details of situated human activities for learning in specific subject domains. The ontogenesis of conceptual change in scientific thinking provides a central case for examining this problem. A sociocultural framework informed by studies of conversation analysis is described, in which meaning negotiation and appropriation are identified as mechanisms for achieving such conceptual change. Key implications of this perspective for the design and study of learning environments are outlined.

Metalearning and conceptual change

Conceptual change means the commitment to a new belief about a principle or a phenomenon, and the abandoning of an old one. Promotion of a new belief is relatively easy, but it is difficult to get students to abandon their former beliefs. Conflicting beliefs can be held by a learner. This article argues that the resolution of conflicting beliefs requires elements of metalearning (conscious control over one's learning).

The work of the Project to Enhance Effective Learning (the peel project), which attempts to promote metalearning in a secondary school is described and some general principles derived from the experience of the project are outlined. It is suggested that the key to the acceptance of metalearning strategies by students parallels the conditions for promoting conceptual change specified by Posner et al. (1982) and in particular in the acceptance of the fruitfulness of the new approaches. It is argued that this requires changes in the organization of schooling, particularly adoption of methods of assessment that reward understanding.     

Understanding conceptual change: connecting and questioning

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 role of hypothetico-deductive reasoning and physical analogues of molecular interactions in conceptual change

Two hypotheses about theoretical concept acquisition, application, and change were tested. College biology students classified as intuitive, transitional, or reflective (hypothetico-deductive) reasoners were first taught two theoretical concepts (molecular polarity and bonding) to explain the mixing of dye with water, but not with oil, when all three were shaken in a container. The students were then tested in a context in which they misapplied the concepts in an attempt to explain the gradual spread of blue dye in standing water. Next students were taught another theoretical concept (diffusion), with and without the use of physical analogues. They were retested to see which students acquired the concept of diffusion and which students changed from use of the incorrect polarity and bonding concepts (i.e., the misconceptions) to use of the diffusion concept to correctly explain the dye's gradual spread. As predicted, the experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion. Also as predicted, hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept and to a change from the misapplication of the polarity and bonding concepts to the correct application of the diffusion concept to explain the gradual spread of the blue dye. Thus, the results support the hypotheses that physical analogues are helpful in theoretical concept acquisition and that hypothetico-deductive reasoning is needed for successful concept application and change. Educational implications are drawn.     

Conceptual mediation: A new perspective on conceptual exchange

For the last two decades science education researchers have had a major interest in identifying students’ intuitive understanding of a wide range of scientific topics and in reducing the difficulties involved when an attempt is made to replace these views by scientific understanding. Different approaches to this latter problem have been adopted by researchers, with strategies ranging from the pragmatic and atheoretical to those with a stronger theoretical foundation, usually based on some form of constructivism. In this paper we report on a novel theoretical perspective which takes as its foundation the psychological research of about three decades ago which investigated “forgetting,” and the important effects of previous knowledge in this process. In particular this new perspective demonstrates that, under normal teaching conditions, and through the process of proactive inhibition, the student’s prior knowledge can accelerate the forgetting of the newly taught scientific ideas. The paper first develops the theoretical position and then shows that a change in teaching approach can take advantage of the differences between the students’ prior understanding and the scientific view to ensure more efficient replacement. Following this an overview of the new methodology, as it is currently being used on a trial basis by science teachers in South Australia, is briefly introduced.     

Classroom conceptual change: philosophical perspectives

Researchers of students’ concepts and conceptual change frequently draw analogies to the history of science. The analogy is generally presented when comparing students’ scientific concepts to similar ones in the history of science. We have tried to show the importance of this analogy on a higher level ‐‐ that of understanding the process of conceptual change in general among students.

This article outlines a number of lines in the philosophy of science and analyses differences between the perspectives of a number of broadly constructivist positions which have developed during this century.

The analysis is used to clarify the theoretical basis on which research into student conceptual change is conducted and interpreted.     

Kuhn and conceptual change: on the analogy between conceptual changes in science and children

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.     

Conceptual change and the learning of history

This paper examines conceptual change as found in the domain of history. It is argued that while history does not have central concepts in the same manner as the physical sciences, history does have alterantive frameworks which are at different levels of explanation. Causal explanations and structural explanations are considered and student personalization of structures is emphasized. It is concluded that conceptual change in history is in part due to difficulties in determining to which theoretical context a concept belongs.     

Theory of mind and conceptual change

We agree with the commentaries by Scholl and Leslie, and also by Moses, that the meta-analytic findings do not definitively rule out early competence accounts. But they do make extant versions of such accounts increasingly unlikely. In particular, the meta-analytic findings argue against executive function expression accounts, including the Theory-of-Mind Mechanism/Selection Processor account advocated by Scholl and Leslie. Specifically, Scholl and Leslie articulate two explicit predictions of their account: that task manipulations that attenuate inhibitory demands should differentially advantage older children, and that theory-of-mind developments should occur with consistent timetables. Both of these specific predictions are clearly contradicted, not supported, by the meta-analytic findings.     

Decolonizing posthumanism: Indigenous material agency in generative STEM

This paper describes a decolonial perspective on material agency in the context of STEM education and application. Using the framework of generative STEM, we engaged in case studies with African, African American, South American, and Native American educational communities. This research shows that understanding material agency based on Indigenous knowledge systems can open a rich source of research and education content. Using a suite of simulations, Culturally Situated Design Tools, we apply this body of research to the classroom. One important theoretical conclusion is the contrast to a “content agnostic” position. A generative framework instead offers a robust blend of user agency and instructional guidance. The outcomes indicate statistically significant and notable improvement for STEM skills and interests. We conclude with a contrast to the quantum epistemology approach to posthumanism. We show that the Indigenous material agency framework in generative STEM is a better fit to decolonial aspirations, and that it offers a more transformative vision for the potential role of STEM in transitioning from an extractive to a generative economy.     

The role of conceptual conflict in conceptual change and the design of science instruction

Conceptual conflict has long been recognized as a factor that could facilitate student learning. Due, however, to the lack of a convincing explanation of why it occurs, and how it can be resolved, it has seldom been used in instructional design. Its potential use in instruction is particularly relevant in the light of the recent, well-documented finding that students' existing conceptions frequently constitute a barrier to effective learning. This article examines conceptual conflict in the light of an epistemological model of learning as conceptual change. This analysis shows that the conceptual change model provides an explanation of conceptual conflict which is sufficiently detailed to allow it to be used in the design of instruction. The results of two studies, the first of which addressed the concepts of mass, volume, and density, and the second, the concept of speed, show that instruction, designed in this way, is effective in changing students' existing conceptions.     

Transfer and conceptual change: the change process from the theoretical perspectives of coordination classes and phenomenological primitives

The purpose of this study is to understand the nature of pre-instructional knowledge transferred by students into problem situations and the change process on students’ knowledge system during classroom discussions. This study was framed by two interrelated theoretical frameworks on knowledge structures, phenomenological primitives and coordination classes. The data were collected through problem solving sessions on turning effect of forces (torques or moment) from ten participants who were seeking a degree to become physics teachers. The analysis of data showed that, in this particular context, students’ pre-instructional ideas can be characterized according to phenomenological primitives. The theoretical constructs of the coordination classes generated meaningful results to understand students’ particular difficulties in transferring the moment concept across different contexts and the change process on students’ knowledge system. The major stimulator of the change process emerged as the students’ becoming aware of the epistemological nature of their knowledge structures and searching the causal mechanisms behind physical phenomena.     

Textual and graphical refutations: Effects on conceptual change learning

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.     

Teacher agency within the context of formative teacher assessment: an in-depth analysis

Teachers’ agency has an effect on their own learning process at the workplace. In this study we explored the extent to which teachers participating in a formative teacher assessment procedure developed a sense of agency. We investigated not only whether teachers participating in a such an assessment procedure experienced agency and thus felt in control of the learning process and able to pursue their learning objectives, but also whether agency was visible, by looking at decision-making in real time: did teachers take an active role in their own assessment, especially regarding the learning objectives to be pursued, during the assessment meetings? We found that teachers experienced a high level of agency while participating in the assessment procedure, but did not consistently show this during the assessment procedure.     

Discussing the Greenhouse Effect: children's collaborative discourse reasoning and conceptual change

In environmental education the construction of appropriate knowledge is not enough, but is undoubtedly a fundamental component of individual and collective environmental responsiveness. The aim of this study was to investigate fifth graders' changes of conceptions about the greenhouse effect and global warming, due to socio‐cognitive interaction developed in small and large group discussions in an authentic classroom context during the implementation of an environmental education curriculum unit. We hypothesized that a classroom transformed into a community of discoursei.e. a learning environment which stimidates and supports giving verbal explanations, comparing and critically evaluating different points of view on the examined environmental phenomenon, would be a fruitful breeding ground for knowledge revision. The results show that classroom discussions, the core of the proposed learning activity, led the children, although at different levels, to the integration of new scientific knowledge into their conceptual ecology, based on the personal revision of pre‐instructional conceptions. As hypothesized, a high positive correlation was found between conceptual change and metaconceptual awareness of the changes in pre‐existing representations of the examined phenomenon. Some implications are drawn from the standpoint of environmental education.     

Patterns of conceptual change in evolution

The purpose of this study was to investigate the patterns of students' conceptual restructuring within the theoretical framework of biologic evolution. The study draws on conceptual change theory in an effort to define the limits of the theory and suggest other models of restructuring. Through a series of 17 structured and open-ended interviews with each of 4 participants, the students' changing conceptions about facets of evolutionary theory were documented throughout the school year. Interview questions were developed from the wealth of alternative conceptions documented in the literature, and many interview techniques were employed to assure the mode validity of all research findings. The conceptual change documented demonstrates that many conceptions in this content area are closely interwoven, so that a change in one conception requires a change in many others. Four patterns of conceptual change were seen: (a) cascade, (b) wholesale, (c) incremental, and (d) dual constructions. Of these 4, only 2 conform to the changes described by conceptual change theory. The other two patterns suggest that different models of conceptual restructuring are required for further science education research. © 1996 John Wiley & Sons, Inc.     

Toward an explanation of conceptual change

In this paper, an alternative ‘explanation’ of conceptual change is offered. It is argued that the problem of explaining conceptual stability and change can be divided into three parts; accounting for conceptual change entails specifying some factors affecting each of the following: old conceptions’ persistence, new conceptions’ acquisition, and cognitive restructuring. Some factors affecting each sub‐problem are discussed, and the literature is reviewed to support the significance of these factors.
