Enhancing the Quality of Argumentation in School Science
The research reported in this paper focussed on the design of learning environments that support the teaching and learning of argumentation in a scientific context. The research took place over two years between 1999 and 2001 in junior high schools in the greater London area. The research was conducted in two phases. In the first developmental phase, working with a group of 12 science teachers, the main emphasis was to develop sets of materials and strategies to support argumentation in the classroom and to assess teachersâ development with teaching argumentation. Data were collected by videoing and audio recording the teachers attempts to implement these lessons at the beginning and end of the year. During this phase, analytical tools for evaluating the quality of argumentation were developed based on Toulminâs argument pattern. Analysis of the data shows that there was significant development in the majority of teachers use of argumentation across the year. Results indicate that the pattern of use of argumentation is teacher specific, as is the nature of the change. In the second phase of the project, teachers taught the experimental groups a minimum of nine lessons which involved socioscientific or scientific argumentation. In addition, these teachers taught similar lessons to a control group at the beginning and end of the year. Here the emphasis lay on assessing the progression in student capabilities with argumentation. Hence data were collected from several lessons of two groups of students engaging in argumentation. Using a framework for evaluating the nature of the discourse and its quality, the findings show that there was an improvement in the quality of studentsâ argumentation. In addition, the research offers methodological developments for work in this field
Science communication in the media and human mobility during the COVID-19 pandemic: a time series and content analysis
Objectives
The relationship between human mobility and nature of science (NOS) salience in the UK news media was examined.
Study design
This is a mixed-method study.
Methods
A time series NOS salience data set was established from the content analysis of 1520 news articles related to non-pharmaceutical interventions of COVID-19. Data were taken from articles published between November 2021 and February 2022, which correlates with period of the change from pandemic to endemic status. Vector autoregressive model fitting with human mobility took place.
Results
The findings suggest that it was not the number of COVID-19 news articles nor the actual number of cases/deaths, but the specific NOS content that was associated with mobility change during the pandemic. Data indicate a Granger causal negative direction (P 0.1).
Conclusions
The findings of the study suggest that the ways in which the news media discuss epidemics can influence changes in human mobility. It is therefore essential that public health communicators emphasise the basis of scientific evidence to eliminate potential media bias in health and science communication for the promotion of public health policy. The present study approach, which combines time series and content analysis and uses an interdisciplinary lens from science communication, could also be adopted to other interdisciplinary health-related topics
The role of research experiences in developing pre-service teachersâ epistemic beliefs
Persistent concerns about the theory-practice gap and desires for an âevidence-informedâ teaching profession have prompted research into how teachers' epistemic beliefs influence their acceptance or rejection of educational research. This study analyses longitudinal interview data from six pre-service teachers (PSTs) to explore how experiences of conducting research (in the domains of science or education) during initial teacher education (ITE) contribute to epistemological development. These research experiences provided opportunities for ad-hoc epistemological development, even in the absence of intentional efforts. Epistemic beliefs sometimes appeared to be supplanted, counterproductively, from science to education. The implications for teacher education and research are discussed
Does Research on Nature of Science and Social Justice Intersect? Exploring Theoretical and Practical Convergence for Science Education
Even though enhancement of studentsâ understanding of social justice is thought to contribute to good citizenship, contextualising social justice in science education remains challenging for teachers because social justice is not conventionally a common feature of science teaching and learning. A separate issue in science education concerns a vast body of work on nature of science (NOS) elated to understanding of and about science. Understanding NOS is thought to contribute to scientific literacy as well as citizenship. Although social justice and NOS literatures share similar themes such as citizenship goals, the precise intersection of these literatures remains relatively understudied. In this chapter, we present an argument about how contemporary conceptualizations of NOS as well as NOS instruction might be used to promote goals related to social justice. In so doing, we aim to contribute to NOS literature by drawing on theories of social justice grounded in political philosophy. We trace the potential overlap of social justice and NOS concepts and draw out example recommendations for curriculum statements and practical teaching as well as practical teaching and learning approaches. Overall, we advocate the promotion of educational goals related to social justice through NOS instruction
Learning to Teach Argumentation: Research and development in the science classroom
The research reported in this study focuses on an investigation into the teaching of argumentation in secondary science classrooms. Over a one-year period, a group of 12 teachers from schools in the greater London area attended a series of workshops to develop materials and strategies to support the teaching of argumentation in scientific contexts. Data were collected at the beginning and end of the year by audio and video recording lessons where the teachers attempted to implement argumentation. To assess the quality of argumentation, analytical tools derived from Toulmin's argument pattern (TAP) were developed and applied to classroom transcripts. Analysis shows there was development in teachers' use of argumentation across the year. Results indicate that the pattern of use of argumentation is teacher-specific, as is the nature of change. To inform future professional development programmes, transcripts of five teachers, three showing a significant change and two no change, were analysed in more detail to identify features of teachers' oral contributions that facilitated and supported argumentation. The analysis showed that all teachers attempted to encourage a variety of processes involved in argumentation and that the teachers whose lessons included the highest quality of argumentation (TAP analysis) also encouraged higher order processes in their teaching. The analysis of teachers' facilitation of argumentation has helped to guide the development of in-service materials and to identify the barriers to learning in the professional development of less experienced teachers

Analytic frameworks for assessing dialogic argumentation in online learning environments
Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in argumentation. This review first considers the range of functionalities incorporated within these online environments. The review then presents five categories of analytic frameworks focusing on (1) formal argumentation structure, (2) normative quality, (3) nature and function of contributions within the dialog, (4) epistemic nature of reasoning, and (5) patterns and trajectories of participant interaction. Example analytic frameworks from each category are presented in detail rich enough to illustrate their nature and structure. This rich detail is intended to facilitate researchersâ identification of possible frameworks to draw upon in developing or adopting analytic methods for their own work. Each framework is applied to a shared segment of student dialog to facilitate this illustration and comparison process. Synthetic discussions of each category consider the frameworks in light of the underlying theoretical perspectives on argumentation, pedagogical goals, and online environmental structures. Ultimately the review underscores the diversity of perspectives represented in this research, the importance of clearly specifying theoretical and environmental commitments throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future development of online learning environments for argumentation
