Concept substitution: An instructional strategy for promoting conceptual change

Numerous studies have shown that students often hold conceptions that conflict with accepted scientific ideas, both prior to and after instruction. The failure of instruction to affect students' conceptions can be interpreted as a failure to facilitate conceptual change. In this paper, an instructional strategy will be described that facilitates conceptual change in the special case where conceptual difficulties appear to arise because students confuse related physics concepts. The strategy involves two parts. Firstly, students observe an experiment or demonstration that conflicts with what they expect to see. Secondly, the instructor identifies students' intuitions that are correct but that they have associated with an incorrect physics term, and substitutes the correct physics term. Students can thus develop more scientifically acceptable understandings of physics concepts without having to give up their intuitive ideas. The use of this strategy will be illustrated in two domains of physics. Specializations: physics education, conceptual development, instructional design, improvement of tertiary science education.     

Use of task-value instructional inductions for facilitating engagement and conceptual change

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.     

Learning in Earth and space science: a review of conceptual change instructional approaches

In response to calls for research into effective instruction in the Earth and space sciences, and to identify directions for future research, this systematic review of the literature explores research into instructional approaches designed to facilitate conceptual change. In total, 52 studies were identified and analyzed. Analysis focused on the general characteristics of the research, the conceptual change instructional approaches that were used, and the methods employed to evaluate the effectiveness of these approaches. The findings of this review support four assertions about the existing research: (1) astronomical phenomena have received greater attention than geological phenomena; (2) most studies have viewed conceptual change from a cognitive perspective only; (3) data about conceptual change were generated pre- and post-intervention only; and (4) the interventions reviewed presented limited opportunities to involve students in the construction and manipulation of multiple representations of the phenomenon being investigated. Based upon these assertions, the authors recommend that new research in the Earth and space science disciplines challenges traditional notions of conceptual change by exploring the role of affective variables on learning, focuses on the learning of geological phenomena through the construction of multiple representations, and employs qualitative data collection throughout the implementation of an instructional approach.     

FL-IDE: hypertext for structuring a conceptual design for computer-assisted language learning

A compelling problem for language pedagogues is teaching foreign languages to students so they can retain and use the language skills in real communicative situations. One way to help students learn these skills is to understand and improve current pedagogical approaches to language learning. New technology such as Computer-Assisted Language Learning (CALL) provides pedagogues with rich, multimedia environments for presenting instruction. At the same time, deciding what to present and how to organize the instruction in CALL provides a new challenge. In response to this problem, we discuss preliminary results of a research effort for developing an instructional design environment (IDE) that is uniquely tailored to the needs of developing foreign language instruction. Hypertext features in the IDE software are used to capture and organize into one coherent framework the corpora of theoretical, instructional, and content material that affects foreign language instruction.     

The role of analogies in promoting conceptual change in biology

Four analogies which were used to teach biology topics by four different teachers were analysed from different theoretical perspectives to determine the key role they had to play in the process of conceptual change. A supermarket analogy for the classification of living things was described using the Posner et al. (1982) view of conceptual change as having the role of a sense maker. A car cooling system analogy for human temperature homeostasis was found to play the role of a memory aid and was best explained by considering Vosniadou's (1994) framework theory and mental models perspective of conceptual change. A fluid mosaic analogy for cell membranes was used by the teacher as a transformer and was best explained by Chi et al.'s (1994) ontological category perspective of conceptual change. Finally, a bucket and pump analogy used to teach the stucture and function of the heart was described as a motivator and was viewed through the motivational perspective of conceptual change of Pintrich et al. (1993). The paper concludes that learning in different situations can best be explained by different perspectives of conceptual change and that these perspectives have much to tell us about the normal shifts in conceptual understanding as well as radical conceptual change.     

A conceptual framework for comparing instructional design models

Instructional design (ID) professionals typically employ models that guide their practice. However, it is unclear how a specific model is selected for an instructional situation. Andrews and Goodson (1980) provided a valuable procedure for comparing instructional design models, but because of the proliferation of variations in instructional design applications during the past decade, the introduction of instructional design into new learning contexts and the emergence of alternative approaches to instructional design, there has emerged a need for a new framework which assesses the potential success of any instructional design model. A framework is presented here which is intended to provide a conceptual tool for determining appropriate instructional design applications.     

The role of instructional variables in conceptual change in high school physics topics

This study was conducted to determine the effect of three variables on conceptual change in physics. Ninth and 10th-grade students who, despite instruction, still held nonscientific intuitive ideas about the motion of objects participated in viewing a demonstration, engaged in student-to-student discussion, and/or read a refutational text about Newton's laws of motion. Students (N = 310) were randomly assigned within classes to eight groups representing combinations of the three activities and participated in pretesting, instruction, and posttesting. Posttest results revealed that reading the refutational text helped students change their intuitive ideas to scientific ones, while seeing a demonstration affected how students interacted with group and text on some measures. Discussing ideas in a group did not lead to significant learning of scientific notions but, rather, caused students to be less influenced by either the demonstration or the text.     

Increasing empathic capabilities of instructional developers: Evaluation of a three-phase instructional strategy

Thomas Aquinas, who knew more about education and persuasion than almost anybody who ever lived, once said that when you want to convert someone to your point of view, you go over to where he is standing, take him by the hand (mentally speaking), and guide him to where you want him to go. You don’t stand across the room and shout at him. You don’t call him a dummy. You don’t order him to come over to where you are. You start where he is, and work from that position. That’s the only way to get him to change. Sidney Harris (1973)     

Explorations in promoting conceptual change in electrical concepts via ontological category shift

Chi (1992, 1993) Chi et al. (1994) suggests that many of the difficulties encountered by students in learning Physics concepts arise because they attribute the ontology of material substances to these concepts. These concepts are actually a special type of process - 'Constraint-Based Interactions' (CBI). Slotta and Chi (1996) reported on a study where a group of students explicitly trained in the CBI ontology showed significant gains over a control group in problem solving performance in eight simple electric circuit problems. This paper reports on a series of four studies which explore the usefulness of the ontological categorization framework in investigating students' alternative conceptions of electric circuits and in developing a teaching strategy for promoting conceptual change in the learning of basic electric circuitry concepts.     

A strategy for instructional television research

Conclusion In this article an empirical approach to instructional television research has been defined. This approach does not seek to replace theoretical studies but seeks rather to establish, within those institutions using instructional television, a body of knowledge based on empirical generalizations. Many authors have suggested the importance of defining objectives in assessing instruction, but their ideas filter only very slowly through educational systems. Part of this resistance may be traced to the complete revision of assessment instruments required by instruction by objectives, or standards. However, by asking the question, What happens during instruction? it may be possible to devise instructionally useful measures. Similarly, this question presents teaching, research, and production staff with a problem they may be eager to define and solve.     

The instructional gestalt: A conceptual framework and design for educational research

Summary The argument is advanced in this paper that the pattern of educational investigation wherein comparisons are made between so-called “ experimental” and “ conventional” instructional procedures tends to be defective on three counts: the criteria are often inappropriate or contaminated; the assumptions of homogeneity within and independence between “ experimental” and “ control” conditions are met only when these conditions are very grossly conceived; and the results reflect masking and cancellation effects, thereby revealing relatively little about what transpires in an instructional setting. The Instructional Gestalt is proposed as a methodological framework for educational research focusing upon the interactive nature of learner, instructor, and environmental and course variables constituting the instructional setting. Data generated by explorations within this framework can lead to the formulation of hypotheses which, if subsequently supported empirically, can become principles for inclusion in a theory of classroom learning. The nature of investigations proceeding from the Instructional Gestalt framework was clarified by presentation and discussion of an illustrative study. Since this illustration was only a representation in miniature of the larger investigation, the generalizations about teaching-learning suggested by it are of limited scope and subject to change. Nevertheless, these generalizations do indicate the kinds of hypotheses resulting from studies within the Instructional Gestalt framework. This paper summarizes the rationale underlying research on the Instructional Gestalt proceeding under a grant from the Office of Education, U.S. Department of Health, Education, and Welfare. Portions of this rationale have been presented at the annual meetings of the American Psychological Association in 1961 and 1962.     

Integrating failure in case-based learning: a conceptual framework for failure classification and its instructional implications

Employing authentic cases experienced by practitioners in educational contexts is critical to expanding students’ experience and engaging students in authentic problems to promote their real-world problem-solving skills. Although in real life, practitioners experience both success and failure and learn from both, little research has been done so far to conceptualize why and how failure should be employed in case-based learning (CBL) as a way to develop students’ abilities to solve ill-structured problems. The goal of this paper is to theoretically justify the need for integrating failure cases in CBL to help students become better problem solvers. To achieve this, this paper attempted to approach failure from the perspective of human error and proposed a classification of failure based on the degree of explicitness of human error involved in problem solving. Based on discussions of potential benefits and challenges of integrating different types of failure cases in education, this paper also proposed instructional design strategies that can help facilitate better use of failure cases.

     

Dialogue as a catalyst for teacher change: A conceptual analysis

Teacher–teacher dialogue is a central activity within many professional learning programmes. Understanding how and why dialogue works as an effective tool for teacher change is a question, however, that needs more careful probing in the extant literature. In this paper, I draw upon the philosophical theory of practical reason in order to show why and how teacher–teacher dialogue plays such a crucial role in the evolution of teacher practice. This conceptual analysis also builds our understanding as to the kinds of teacher–teacher dialogues that are more likely to be effective at catalysing teacher learning.     

Model building for conceptual change

Conceptual change is a popular, contemporary conception of meaningful learning. Conceptual change describes changes in conceptual frameworks (mental models or personal theories) that learners construct to comprehend phenomena. Different theories of conceptual change describe the reorganization of conceptual frameworks that results from different forms of activity. We argue that learners' conceptual frameworks (mental models or personal theories) resulting from conceptual change are most acutely affected by model-based reasoning. Model-based reasoning is engaged and fostered by learner construction of qualitative and quantitative models of the content or phenomena they are studying using technology-based modelling tools. Model building is a powerful strategy for engaging, supporting, and assessing conceptual change in learners because these models scaffold and externalize internal, mental models by providing multiple formalisms for representing conceptual understanding and change. We demonstrate the processes and products of building models of domain content, problems, systems, experiences, and thinking processes using different technology-based modelling tools. Each tool provides alternative representational formalisms that enable learners to qualitatively and quantitatively model their conceptual frameworks.     

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.     

Research practice partnerships: a strategy for promoting evidence-based decision-making in education

Abstract

Background: In the United States, an emphasis on evidence-based decision-making in education has received renewed interest with the recent passage of the Every Student Succeeds Act. However, how best, in practice, to support the use of evidence in educational decision-making remains unclear. Research Practice Partnerships (RPPs) are a popular strategy for cultivating evidence-based decision-making among educators, but understanding the ways in which partnerships can influence educators’ use of research evidence in their decision-making is limited.

Purpose: This paper explores the influence that Research Practice Partnerships can have on educators’ evidence-based decision-making.

Sources of evidence: A framework is offered for examining the impact of Research Practice Partnerships on behaviours such as educators’ evidence-based decision-making, in the context of school and district improvement efforts. The framework suggests a host of intermediary and long-term outputs: for example, the ‘mindsets’ of researchers and practitioners which are most conducive to enabling evidence-based decision-making among those engaged in Research Practice Partnerships. We explore this framework through short illustrations of the experiences of three Research Practice Partnerships, contextualising the ideas within the literature, and presenting the process of our design and pilot of a survey instrument used to examine the perceived impact of Research Practice Partnerships.

Main argument: We argue that participants’ self-reported behaviours and perceptions are important elements in examining the influence of Research Practice Partnerships on educators’ evidence-based decision-making. Additionally, this paper examines the potential benefits and challenges of attempting to measure the outputs and outcomes of a Research Practice Partnership using a survey measure.

Conclusions: The process of developing the pilot survey suggests that certain conditions in Research Practice Partnerships may be more conducive to the development among educators of behaviours, mindsets and perceptions associated with evidence-based decision-making.
