Conceptual change: a discussion of theoretical, methodological and practical challenges for science education

Conceptual change views of teaching and learning processes in science, and also in various other content domains, have played a significant role in research on teaching and learning as well as in instructional design since the late 1970s. An important issue is whether conceptual change can provide a powerful framework for improving instructional practice in such a way that students’ levels of scientific literacy are significantly increased. In this article, the first section provides an overview on the development of conceptual change perspectives. In sections two to six, we examine the different ways that researchers have facilitated the collection of data and empirically evaluated learning as conceptual change based on these different theoretical perspectives. In section seven, we identify key issues of conceptual change with a deliberate emphasis on their contribution to improve instructional practice and conclude the article by posing challenges at theoretical, methodological and practical levels. We contend that conceptual change perspectives still have the potential to significantly improve instructional practice. However, it becomes also evident that actual practice is far from what conceptual change perspectives propose and that change of this practice will be a rather difficult and long-lasting process.

The complexities and challenges of regional education hubs: focus on Malaysia

The race to establish regional education hubs is a recent development in cross-border higher education. This article briefly examines the rationales and strategies used by three countries in the Middle East and three in South East Asia which are working towards positioning themselves as regional education hubs. The different approaches and purposes among the six countries highlight the need for a typology of education hubs. Three types are proposed: the student hub, the training and skilled workforce hub, and the knowledge/innovation hub. The final section of the paper takes a closer look at Malaysia??s cross-border education initiatives and its actions to establish itself as a competitive education hub in a region where Singapore and Hong Kong have similar intentions. Whether Malaysia has the ability to make a quantum leap from being a student hub to becoming a knowledge/innovation hub remains to be seen and appears to be an optimistic outlook.     

Researching shadow education: methodological challenges and directions

Research on shadow education has considerably increased in volume and has helped to improve understanding of the scale, nature, and implications of the phenomenon. However, the field is still in its infancy. Literature on shadow education reflects confusion over terms and parameters, and data suffer from challenges in securing evidence from actors who may be unwilling or unable to respond to enquiries in a clear manner. Particular care is needed in cross-national and cross-cultural comparisons. Nevertheless, the trajectory of improvement in both conceptualisation and instrumentation gives ground for confidence that shadow education will be progressively better documented and better understood.     

Speaking back to the deficit discourses: a theoretical and methodological approach

The educational attainment of Aboriginal and Torres Strait Islander students is often presented within a deficit view. The need for Aboriginal and Torres Strait Islander researchers to challenge the societal norms is necessary to contribute to the struggle for self-determination. This paper presents a theoretical and methodological approach that has enabled one researcher to speak back to the deficit discourses. Exemplification of how Indigenous Critical Discourse Analysis (in: Hogarth, Addressing the rights of Indigenous peoples’ in education: A critical analysis of Indigenous education policy, Queensland University of Technology, Brisbane, 2016) identifies the power of language to maintain the inequitable positioning of Aboriginal and Torres Strait Islander peoples within Australian society is provided. Particular focus is placed on the Aboriginal and Torres Strait Islander Education Action Plan 2010–2014 (in: MCEECDYA, Aboriginal and Torres Strait Islander Education Action Plan (2010–2014), 2011) and how policy discourses ignore the historical, political, cultural and social factors that influence the engagement and participation of Indigenous peoples in education today. The paper argues for the need to personalise methodological approaches to present the standpoint of the researcher and, in turn, deepens their advocacy for addressing the phenomenon. In turn, the paper presents the need to build on existing Indigenous research frameworks to continue advocating for the position of Indigenous research methodologies within the Western institution.     

Learning in the liminal space: a semiotic approach to threshold concepts

The threshold concepts approach to student learning and curriculum design now informs an empirical research base comprising over 170 disciplinary and professional contexts. It draws extensively on the notion of troublesomeness in a ‘liminal’ space of learning. The latter is a transformative state in the process of learning in which there is a reformulation of the learner’s meaning frame and an accompanying shift in the learner’s ontology or subjectivity. Within the extensive literature on threshold concepts, however, the notion of liminal space has remained relatively ill-defined. This paper explores this spatial metaphor to help clarify the difficulties that some teachers observe in the classroom in regard to their students’ understanding. It employs a novel and distinctive approach drawn from semiotic theory to to provide some explanatory insight into learning within the liminal space and render it more open to analysis. The paper develops its argument through four distinct phases. Firstly it explores the spatial metaphor of liminality to gain further purchase on the nature of this transformative space. The second section introduces semiotic theory and indicates how this will be used through a series of graphical and visual devices to render the liminal space more open to analysis. The third section then employs semiotic analysis to nine dimensions of pedagogical content knowledge to gain further insight into what may characterise student conceptual difficulty within the liminal state. The fourth and concluding section emphasises the role of context in conceptual discrimination before advocating a transactional curriculum inquiry approach to future research in this field.     

Emotion regulation as a scientific construct: methodological challenges and directions for child development research

Emotion regulation has emerged as a popular topic, but there is doubt about its viability as a scientific construct. This article identifies conceptual and methodological challenges in this area of study and describes exemplar studies that provide a substantive basis for inferring emotion regulation. On the basis of those studies, 4 methods are described that provide compelling evidence for emotion regulation: independent measurement of activated emotion and purported regulatory processes; analysis of temporal relations; measurement across contrasting conditions; and multiple, convergent measures. By offering this perspective, this article aims to engage thoughtful debate and critical analysis, with the goal of increasing methodological rigor and advancing an understanding of emotion regulation as a scientific construct.     

Researching policy borrowing: Some methodological challenges in comparative education

This article considers some of the methodological challenges involved in investigating, within the traditions of comparative research in education, the complex issue of educational ‘policy borrowing’. It discusses notions of ‘borrowing’ and ‘influence’ and refers to a model previously proposed by the authors for the analysis of what are seen as four stages in the policy borrowing process which can be tested empirically. These are identified as cross‐national attraction, decision, implementation, and internalization/indigenization. The problems involved in researching each stage of this process are considered, in particular in relation to the authors’ previous work on the attractiveness to British observers of educational policy in Germany over a long historical period.

Threshold concepts in research education and evidence of threshold crossing

Most work on threshold concepts has hitherto related to discipline‐specific undergraduate education, however, the idea of generic doctoral‐level threshold concepts appeared to us to provide a strong and useful framework to support research learning and teaching at the graduate level. The early work regarding research‐level threshold concepts is further developed and reported in this paper using research carried out with supervisors into their identification of threshold concepts and research students' crossing of these thresholds. The research was conducted in two stages involving 65 experienced research supervisors across six countries (Australia, England, Jamaica, Malaysia, New Zealand and Trinidad) and across Humanities, Social Sciences, Engineering and IT and the Sciences. The first stage involved written responses from 26 experienced supervisors related to the learning challenges experienced by research students and their supervisors. The second stage of the research involved in‐depth interviews with 39 supervisors regarding student learning challenges and successes at the research level. Responses were analysed, resulting in the identification of six possible generic research threshold concepts, which evidence themselves in the quality and level of the students' work at different stages in that work: argument; theorising; framework; knowledge creation; analysis and interpretation; and paradigm. The data analysis also suggests a number of indicators that signal when learners have crossed conceptual thresholds to gain, articulate and put into practice one or more of these threshold concepts in their research learning.     

Scaffolding for argumentation in hypothetical and theoretical biology concepts

ABSTRACT

The present study investigated the effects of online argumentation scaffolding on students’ argumentation involving hypothetical and theoretical biological concepts. Two types of scaffolding were developed in order to improve student argumentation: continuous scaffolding and withdraw scaffolding. A quasi-experimental design was used with four 8th-grade classes comprising a total of 124 students. Two classes (63 students) were assigned into the continuous scaffolding group, while the other two (61 students) were assigned into the withdraw scaffolding group. All the students participated in online argumentation regarding four units, including two hypothetical concepts and two theoretical concepts. Both online learning process and scientific argumentation assessment results indicated that the continuous scaffolding group performed significantly better in terms of the quality and quantity of argumentation than the withdraw scaffolding group with regard to the hypothetical biology concepts, particularly in generating rebuttal arguments. In addition, the results also showed that both the continuous group and withdraw group students had better argumentation performance with regard to the hypothetical biology concepts than the theoretical biology concepts. Taken together, the study results suggest that learning argumentation through theoretical biology concepts is more difficult than doing so through hypothetical biology concepts.     

Making sense of theoretical frameworks and methodological approaches: Exploring conceptual change and interest in learning from a sociocultural perspective

Educational psychology has a tradition of considering learning and motivation in terms of the individual and individual functioning. Short-term intervention studies have been common and quantitative measurement of the causes and effects of variables has been the aim of much research. When a sociocultural approach forms the basis of research into psychological constructs, a reappraisal of the research aims and the ways in which data are gathered and analysed is necessary. If the underlying assumption is that learning and motivation are socially and culturally situated, the design of research studies needs to encompass participation in authentic and purposeful activities. In order to develop a rich sociocultural understanding of these constructs, qualitative research designs become increasingly important. In this article, we consider two current research projects, one focusing upon conceptual change amongst students in a first year university class, and the other a classroom-based qualitative study exploring primary (elementary) students’ interest in learning. In each project, data have been collected over time in relation to both social interaction and individual functioning in specific sociocultural contexts. Our frameworks for data collection and approaches to data analysis are discussed in this article, together with some of the issues which we have identified as problematic. In particular we are conscious of the difficulties associated with articulating and describing the nature of social and cultural contexts, especially those with which we are familiar, and of distinguishing their most salient features. We are also critically aware that because our research is situated within very familiar environments, we need to identify and explore our implicit assumptions about those environments and the ways in which our roles as teachers and researchers both coincide and occasionally conflict.     

Phonological codes as early sources of constraint in Chinese word identification: A review of current discoveries and theoretical accounts

A written Chinese character has a more direct connection with its meaning than a written word in English does. Moreover, because there is no unit in the writing system that encodes single phonemes, grapheme-phoneme mappings are impossible. These unique features have led some researchers to speculate that phonological processing does not occur in visual identification of Chinese words or that meaning is activated earlier than phonology. This hypothesis, however, has been challenged by more recent discoveries that suggest that phonology in Chinese, just as in English, is central to the visual recognition system. The present paper reviews the literature on phonological codes as early sources of constraint in Chinese word identification and considers the specific aspects of phonological and orthographic processing in Chinese that may differ from those in English. It emphasizes that early phonological processes and phonological mediation are two different questions in the identification-with-phonology hypothesis. Mediation and prelexical phonology, two very important concepts in the literature on phonological computation in reading English, are both misleading in Chinese.     

The study on the core concepts of contemporary sociology of education and its theoretical construction

Within the sphere of contemporary social sciences, the terms “modernity,” “post-modernity” and “globalization” have penetrated, as the core concepts, into various fields of social sciences in a logical way. In constituting the concept of “modernity,” sociology of education develops the educational theory, as sociological theory does, into a “grand narrative” and “foundationalist” theory; the contribution of post-modernity is pluralism and self-examination in an attempt to transcend modernity. Globalization, a kind of expanded modernity, makes education sociologists broaden their perspective from single and traditional “nationality,” “society” and “nation” to an international society and even to the global society, which has broken through the research paradigm of modernity with ethnocentrism, anthropocentrism and Euro-centrism. These changes have required urgent constitution of the conceptions and theoretical frameworks of sociology of education to be applied on a global level. __________ Translated from Peking University Education Review, 2006 (1)     

Time sampling: a methodological critique

Numerous developmental studies of social behavior employ an observational technique called time sampling. This technique is used to estimate the frequencies and proportions of time that actual behaviors occur and to measure group or individual differences. By contrasting time sampling to continuous sampling, we demonstrate that (a) time sampling is inaccurate for estimating actual durations or frequencies of behavior, and (b) resulting individual and/or group differences can change depending on whether time sampling or continuous sampling is used. Error rates are particularly high when the total bout lengths of the actual behaviors are short (as in mother-infant interactions) and/or when interval length is long. Because the majority of mother and infant behaviors are short in bout length (less than 60 sec), when percent error is the greatest, we suggest that alternative sampling methods that have proven validity be used in future studies (e.g., scan, point, or continuous sampling).
