Children's conceptions of air pressure: exploring the nature of conceptual change

Children's responses to a series of air pressure activities were tracked in detail during group discussion and interview, and again in interview six months later. Results for different age cohorts have yielded insights into age‐related knowledge components framing children's conceptions of air pressure phenomena. Case studies of individuals have been constructed to explore the way conceptions change over time, and the difficulties presented by the concept of atmospheric pressure. These are used to evaluate different structural theories of conceptual change. The findings point to the complexity of children's conceptions, the stability and extension over time of productive conceptions, and the critical role of contextual features of phenomena in the conceptual change process. Although structural aspects of changes in concepts related to air pressure are identified, the difficulty of accessing the atmospheric pressure conception is argued to have more to do with presupposition based in perceptual features of air, and with difficulties associated with the application to particular phenomena.     

Young children learning about living things: A case study of conceptual change from ontological and social perspectives

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

Sociocultural frameworks of conceptual change: implications for teaching and learning in museums

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.

Facial micro-expression states as an indicator for conceptual change in students' understanding of air pressure and boiling points

Utilizing facial recognition technology, the current study has attempted to predict the likelihood of student conceptual change with decision tree models based on the facial micro-expression states (FMES) students exhibited when they experience conceptual conflict. While conceptual change through conceptual conflicts in science education is a well-studied field, there is little research done on conceptual change through conceptual conflict in terms of students' facial expressions. As facial expressions are one of the most direct and immediate responses one can get during instruction and that facial expressions are often representations student's emotions, a link between students' FMES and learning was explored. Facial data was collected from 90 tenth graders. Only data from the 72 students who made incorrect predictions were analyzed in this study. The concept taught was the relationship between boiling point and air pressure. Through facial recognition software analysis and decision tree models, the current study found Surprised, Sad and Disgusted to be key FMES that could be used to predict student conceptual change in a conceptual conflict-based scenario.     

Classroom management of situated group learning: A research study of two teaching strategies

Although peer-based work is encouraged by theories in developmental psychology and although classroom interventions suggest it is effective, there are grounds for recognising that young pupils find collaborative learning hard to sustain. Discontinuities in collaborative skill during development have been suggested as one interpretation. Theory and research have neglected situational continuities that the teacher may provide in management of formal and informal collaborations. This experimental study, with the collaboration of the science faculty in one urban secondary college, investigated the effect of two role attribution strategies on communication in peer groups of different gender composition in three parallel Year 8 science classes. The group were set a problem that required them to design an experiment to compare the thermal insulating properties of two different materials. This presents the data collected and key findings, and reviews the findings from previous parallel studies that have employed the same research design in different school settings. The results confirm the effectiveness of social role attribution strategies in teacher management of communication in peer-based work.     

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.     

A conceptual discussion of lesson study from a micro-political perspective: Implications for teacher development and pupil learning

Lesson study has been implemented as a viable approach to support teachers' professional development. Yet, this approach has not been thoroughly examined in relation to key micro-political power relations that are arguably endemic to the use of this collaborative learning model. Accordingly, this paper discusses post-structural concepts that might be used to envision and underpin how teachers come to engage with their students, with their peers, and with external consultants. Taken together, the findings in this paper illustrate how a micro-political perspective can be linked with teachers' professional development as well as their practices of identity construction.     

Student beliefs and learning environments: Developing a survey of factors related to conceptual change

This paper presents a model for the type of classroom environment believed to facilitate scientific conceptual change. A survey based on this model contains items about students' motivational beliefs, their study approach and their perceptions of their teacher's actions and learning goal orientation. Results obtained from factor analyses, correlations and analyses of variance, based on responses from 113 students, suggest that an empowering interpersonal teacher-student relationship is related to a deep approach to learning, a positive attitude to science, and positive self-efficacy beliefs, and may be increased by a constructivist approach to teaching. Specializations: secondary school science learning environments, writing in science, alternative frameworks, the language of science.     

Strategic intelligence: A conceptual system of leadership for change

Strategic intelligence is a conceptual system of leadership qualities. These qualities must be considered in the context of the challenges facing leaders and the relationships between leaders and the people they lead. A leader's philosophy and personality influence the way he or she expresses the qualities of strategic intelligence when things are going according to plan and when leaders face significant conflicts. Leaders can be most effective by tapping into the intrinsic motivations of followers.     

Emerging learning environments in higher education: Implications for institutional change and academic developers

Abstract

Wright and O'Neil's (1995) international survey of promising teaching improvement practices in higher education (HE) placed the existence of teaching support centres close to the top of the thirty‐six item scale. One conclusion that may be drawn from their findings is that many of the responding institutions see the role of academic developer as significant in helping to monitor trends and planning activities that can lead to quality of educational provision. This paper outlines several scenarios relating to learning environments potentially emerging in HE, describes implications for institutional change, and defines key assumptions for bringing about a development culture. Additionally, the paper reviews how these contextual factors may impact on the role of academic developer and concludes with a suggestion for a ‘developers’ curriculum’ that may merit consideration by members of the International Consortium for Educational Development in Higher Education (ICED).     

ASK to THINK-TEL WHY: A model of transactive peer tutoring for scaffolding higher level complex learning

This article presents an inquiry-based model of mutual peer tutoring called ASK to THINK-TEL WHY®©. The model is described along with its purpose, its theoretical and research bases, and how it is used by tutoring partners to mediate each others' learning. Unlike tutoring systems used to promote learning at the comprehension level, this model is designed to promote higher level complex learning, namely the construction of new knowledge. The model emphasizes reciprocal tutor-tutee roles, supportive communication, and (elaborated explanation and questioning skills. When in the tutoring role, students learn to use different kinds of questions to prompt their partners to make corresponding responses. Tutors also learn to sequence their questioning in a particular way. Thus, during this transactive process, partners scaffold each other's thinking and learning to progressively higher levels. Mechanisms involved in this form of peer-mediated learning are discussed along with results of research on the model's effectiveness.     

Lesson study: A collaborative approach to scholarship for teaching and learning in higher education

The Scholarship of Teaching and Learning has become an important field of inquiry, focusing on the development of new and critical pedagogic approaches in higher education. It is a broad field leading to the emergence of a number of contrasting perspectives concerning the development of insights into teaching and learning. In this article, we explore the potential for Lesson Study to act as a framework for reflecting on and developing pedagogic practice in the university sector. Originating in Japan over a century ago, Lesson Study is a collaborative tool for analysing and developing understanding of student learning. This makes it an ideal tool for capturing and interrogating new and critical insights into teaching and learning. An outline framework is suggested for developing the use of Lesson Study in higher education and we discuss how it can form a positive methodology for extending the work of the Scholarship of Teaching and Learning.     

A longitudinal study of conceptual change: Preservice elementary teachers' conceptions of moon phases

This research consists of a longitudinal study of 12 female elementary preservice teachers' conceptual understanding over the course of several months. The context in which the participants received instruction was in an inquiry‐based physics course, and the targeted science content was the cause of moon phases. Qualitative research methods, including observations and interviews, were used to investigate and describe participants' conceptual understanding over time. Participants were interviewed on their understanding of the cause of moon phases before instruction, 3 weeks after instruction, and again in delayed post‐interviews several months after instruction. Patterns and themes in the participants' conceptual understanding were identified through constant‐comparative data analysis. Consistent with results reported earlier, participants who had instruction that included recording and analyzing moon observations over time and psychomotor modeling of changes in moon phases were very likely to hold a scientific conceptual understanding shortly after instruction. The present study indicates a majority of participants continued to hold a scientific understanding six months or more after instruction. However, some participants reverted to alternative conceptions they had shown during the pre‐interview. These results are interpreted utilizing contemporary conceptual change theory. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 44: 303–326, 2007
