Technological Risk,Scientific Advice and Public 'Education': Groping for an adequate language in the case of GM foods

Knowledge is central to both education and sustainability. This article examines a current example of rapid shifts in knowledge and perceptions in education and learning about sustainability in civil society. Through the lens of the public outcry and policy crisis over genetically modified foods in the UK, it points to some major recurring difficulties with policy models of 'public education' used in cases of technological risk. These reveal entrenched policy presumptions that the general public is ignorant about scientific matters and that this ignorance can simply be addressed by better communication. It notes the challenges to these models that have been presented in particular by a group of environmental social scientists in rethinking the politics of GM food in the context of sustainability. It proposes that the term 'ignorance' is one that needs to be applied to the task of risk assessment as much as to the public, and that more inclusive styles of decision making on risk issues are not only more democratic but also more scientifically robust. With innovation occurring at an ever increasing rate, the understanding and management of technological risk will continue to become more important. The knowledge, learning and education involved will be key survival skills if we are to implement sustainability.     

Co-Teaching and Cognitive Spaces: An Interdisciplinary Approach to Teaching Science to Nonmajors

This paper describes a course, Science, Technology and the Public in the Nineteenth Century, which is both interdisciplinary and co-taught by a biologist and an historian. The rationale for including social history in such a course is to make nonscience majors more aware of both the process of science and its relationship to society. An example of the social history component of the course is offered in a discussion of Louis Pasteur and his adulation by the French public. Since Pasteur's popularity was based as much on nonscientific as on scientific factors, we use his career to illustrate concepts about science in its cultural context that we want our students to understand. The course's content is then presented with reference to objectives we hope to achieve. Finally we indicate how, with our varied backgrounds, co-teaching this course led to a sharing of our cognitive spaces and how this was a positive experience for both ourselves and our students.     

Choice Within Constraints: Mothers and schooling

ABSTRACT This article explores the discourses of choice in the context of the current, and international, public policy debates about providing freedom of choice for parents as consumers in the education market place. In particular it explores the public and private discourses of choice to illustrate the argument that mothers as parents are not 'free to choose' but act within a range of constraints. We term these both structural and moral constraints and offer evidence about them as experienced by mothers over time in relation to bringing up children, from resources to negotiations about relationships and expectations about both the nature of family life, employment and their children's place within the future. It also offers some evidence from our various research studies of mothers from their perspectives, about the processes of choice, in the context of both structural and moral constraints, including issues about involvement in their children's education and schooling. Consideration is also given to mothers' evaluations of their satisfaction or dissatisfaction with their possibilities of child rearing and education. The article concludes with the argument that mothers' experiences of the processes of bringing up and educating their children are not at all in harmony with the, albeit contradictory, public policy discourse of their being free to choose. Mothers' various perspectives from their varied vantage points are indeed limited by structural and moral possibilities in a patriarchal and racist society.     

Away with all teachers: The cultural politics of home schooling

In the United States and a number of nations, one of the most powerful dynamics of educational 'reform' involves the movement toward home schooling. The national media have spoken glowingly about it and the number of children being schooled at home is growing rapidly. In large part, this is stimulated by the circulation of anti-statist discourses and by the continuation and expansion of claims about school failure. In these accounts, the sources of educational problems are multiple: teacher education institutions produce teachers who are unprepared academically and unskilled in teaching the 'basics'; state funded (public, in the US sense of the word) schools have been taken over by 'progressive' models of teaching that are unworkable; these same schools do not teach 'traditional' cultural and religious knowledge, beliefs, and values; and public schools do not listen to conservative parents and are much too bureaucratic. Supporters of home schooling are usually religious fundamentalists who have increasing power in the USA and elsewhere. They have formed a national coalition and have joined in a tense rightist hegemonic alliance with neo-liberals and neo-conservatives, an alliance that seeks to reconstruct our common-sense about education and about all things social. The article shows how the movement toward home schooling has become more extensive and more dangerous than has usually been thought. In the process, home schooling is situated within the larger conservative and authoritarian populist ideological, religious, and social movements that provide much of its impetus. Connections are suggested with other protectionist impulses and connections are made to the history of and concerns about the growth of activist government. Finally, the article points to how it may actually hurt many other students who are not home schooled.     

Formations of Mexicana ness: Trenzas de identidades multiples Growing up Mexicana : Braids of multiple identities

As California's complexion and social panorama changes in color and class so must the directions for writing ethnicity and social analysis. This qualitative study seeks to break out of paradigmatic insulation by proposing innovative perspectives and directions for creating subversive narratives about our own realities. It also seeks to inform current social analysis about Mexicana quality of life and about educationalpolicy on Mexicana educacion (education of the whole person) and school cultures. This article examines how Mexicana identities are created, shaped, and developed through the construction of narratives. I interpret these with the analytical tools of trenzas that ''braids'' critical race theory and multidimensional feminist frames, platicas (popular conversations) and cultural intuition, and the engagement of myself, the researcher, and the young Mexicanas participating in the study. By claiming our space and voicing our feelings and meanings about language, Aztlan culture and identity, and womanhood, we correct stereotypic representations that render Mexicanas vulnerable and dismissed from U.S. civic life and public education. In light of the missing discourse about young Mexicana identity formations, this research makes possible trenzas ''braids'' of multiple identities and tools for transforming educational research, curriculum, and the building of education partnerships.     

Exploring Opportunities for Argumentation in Modelling Classrooms

On several levels it can be said that the act of modelling in science is inherently an argumentative act. That is, in virtually all aspects of modelling, from developing a question to judging between competing models that might answer that question, an individual is engaged in persuasive acts. Those acts may be private or public. They may be mental, written or oral, but they are about judging ideas and making sense of them; convincing oneself or others that the ideas and ways of looking at and explaining a phenomenon are useful. These acts are what scientists find exciting. They are what make science intellectually interesting and challenging. Inviting students into this practice is one way to help them learn both the content and process of science. This paper introduces a framework that is attentive to the research on how people learn while simultaneously pushing for curriculum and instruction that engages students in elements of the practice of science. We explore how this framework can be used to foster argumentation by describing the theoretical underpinnings of the framework and using classroom examples to illustrate the utility of the framework for promoting argumentation.

Guiding explanation construction by children at the entry points of learning progressions

Policy documents in science education suggest that even at the earliest years of formal schooling, students are capable of constructing scientific explanations about focal content. Nonetheless, few research studies provide insights into how to effectively provide scaffolds appropriate for late elementary‐age students' fruitful creation of scientific explanations. This article describes two research studies to address the question, what makes explanation construction difficult for elementary students? The studies were conducted in urban fourth, fifth, and sixth grade classrooms where students were learning science through curricular units that contained 8 weeks of scaffold‐rich activities focused on explanation construction. The first study focused on the kind and amount of information scaffold‐rich assessments provided about young students' abilities to construct explanations under a range of scaffold conditions. Results demonstrated that fifth and sixth grade tests provided strong information about a range of students' abilities to construct explanations under a range of supported conditions. On balance, the fourth grade test did not provide as much information, nor was this test curricular‐sensitive. The second study provided information on pre–post test achievement relative to the amount of curricular intervention utilized over the 8‐week time period with each cohort. Results demonstrated that when taking the amount of the intervention into account, there were strong learning gains in all three grade‐level cohorts. In conjunction with the pre–post study, a type‐of‐error analysis was conducted to better understand the nature of errors among younger students. This analysis revealed that our youngest students generated the most incomplete responses and struggled in particular ways with generating valid evidence. Conclusions emphasize the synergistic value of research studies on scaffold‐rich assessments, curricular scaffolds, and teacher guidance toward a more complete understanding of how to support young students' explanation construction. © 2011 Wiley Periodicals, Inc.

MYTHS OF AGING OR AGEIST STEREOTYPES

This paper is about ageist stereotypes dressed-up in the garb of myth that biases perceptions and experiences of being old. The paper argues current ''mythmaking'' about aging perpetuates that which it intends to dispel: ageism. It considers how traditional myths and folklore explained personal experience, shaped social life, and offered meaning for the unexplainable. The current myths of aging perform these same functions in our culture; however, they are based on half-truths, false knowledge, and stated as ageist stereotypes about that which is known. Current myths of aging found in the media and literature of aging are not myths as such, but ''straw man'' statements that attempt to inform; however, they reinforce misconceptions and wrong information about aging as experienced by the vast majority of older people. Recent studies in the cognitive sciences are reviewed to provide insight about the mind's inherent ability to construct categories, concepts, and stereotypes as it responds to experience. These normal processes need to be better understood, particularly regarding how social stereotypes are constructed. Finally, the paper argues that ageist stereotypes when labeled as ''myth'' even in the pursuit of the realities of aging, neither educate the public about the opportunities and challenges of aging nor inform social and health practitioners about the aged. Three research and educational strategies are outlined for critical studies in aging and educational gerontology.     

Gender and Science in the Swedish Compulsory School

This study investigates how Swedish pupils meet chemistry, physics and technology in compulsory school. It explores girls' and boys' actions in and thoughts about these subjects during grades 7 to 9. The pupils come from different worlds determined by gender and social background. In the classroom girls are given, and take upon themselves, the role of keeping lessons together, while boys' attempts to dominate the public arena create disorder. Girls and boys prefer different subject areas. Boys have a practical while girls have a more theoretical approach to science. Girls seek ‘connected knowledge’, and even the successful girls question their understanding. Girls who take an interest in physics and chemistry often have supporting scientist fathers or at least parents with a higher education. Technology is rejected by all girls. The mutual construction and reconstruction of gender and of science/technology contribute to gendered choices of study programmes in upper secondary school.     

Teleology as a tacit dimension of teaching and learning evolution: A sociological approach to classroom interaction in science education

Teleology has been described as an intuitive cognitive bias and as a major type of student conception. There is controversy regarding whether teleological explanations are a central obstacle to, are legitimate in, or are even supportive of science learning. However, interaction in science classrooms has not yet been investigated with regard to teleology. Consequently, this study addresses the question of how teleological explanations emerge in science classroom interactions about evolution and how teachers and students address emerging teleology. In this article, we introduce a theoretical and methodological framework drawing from the sociology of knowledge and systems theory, suggesting that this framework may enrich the understanding of knowledge construction and of social practices in the science classroom because it enables distinguishing between explicit and tacit knowledge. We investigated seven secondary school units about evolution and present data from four grade-12 classes in Germany, a country with very few creationists, to contrast two ways in which teleology is addressed. In the first type, the teachers combine intentional and need-based teleological explanations with aspects of scientific theories in an ambiguous way. Contrastingly, in the second type, the teachers construct a duality between correct mechanistic and incorrect teleological explanations by discrediting preceding scientific theories. In the discussion, we argue that the presented sociological approach can also be valuable in other science education contexts, such as creationism, the nature of science and socio-scientific issues, because classroom interaction involves tacit communication, such as a tacit epistemology, which are essential grounds for the students' knowledge construction.     

Public Communication of Climate Change Science: Engaging Citizens Through Apocalyptic Narrative Explanation

Working from the premise that public input is essential to science policy deliberations, we analyze how two recent works of public communication about climate change (An Inconvenient Truth and Climate Change Show) draw on the rhetorical resource of apocalyptic narrative explanation to promote scientific fluency and inspire citizen engagement in the issues. By weaving together the proofs of ethos, logos, and pathos within a framework of cultural rationality, these narratives illustrate available means of persuasion for stimulating the public's informed participation in science policy discussions.     

University science students' experiences of investigative project work and their images of science

In this paper we consider the ways in which students' activities during project work are influenced by their images of science, e.g. their views about the purposes of science, the nature of scientific knowledge and the role of social processes in scientific activity. We also investigate the kinds of project activities which promote the development of students' images of science. We draw on case studies of 11 science students' experiences of investigative project work in their final year at university. For one of these students naive views about the epistemology of science constrain her project activities. We suggest that the concept of 'epistemic demand' may help in anticipating difficulties that students might have during project work. We also find that students' images of science are developed as a result of messages communicated both implicitly and explicitly through project work.     

Border Pedagogy: A Study of Preservice Teacher Transformation

In our increasingly interconnected global society, learning to think about ourselves in a border context, making crossings and connections, reflecting on our position and power, and articulating a vision of social justice are necessary civic skills. Developing educational border crossers who have moved beyond stereotyping and the tourist's gaze to have a sensibility for social justice can enrich public life and stimulate the deepest forms of civic engagement. This study examines a teacher education program's nascent efforts to develop multicultural competencies, specifically border pedagogy, in future teachers.     

Addressing Challenges to Public Understanding of Science: Epistemic Cognition,Motivated Reasoning,and Conceptual Change

Science is of critical importance to daily life in a knowledge society and has a significant influence on many everyday decisions. As scientific problems increase in their number and complexity, so do the challenges facing the public in understanding these issues. Our objective is to focus on 3 of those challenges: the challenge of reasoning about knowledge and the processes of knowing, the challenge of overcoming biases in that reasoning, and the challenge of overcoming misconceptions. We propose that research in epistemic cognition, motivated reasoning, and conceptual change can help to identify, understand, and address these obstacles for public understanding of science. We explain the contributions of each of these areas in providing insights into the public's understandings and misunderstandings about knowledge, the nature of science, and the content of science. We close with educational recommendations for promoting scientific literacy.     

Exploring identities to deepen understanding of urban high school students' sexual health decision‐making

Sexual health is a controversial science topic that has received little attention in the field of science education, despite its direct relevance to students' lives and communities. Moreover, research from other fields indicates that a great deal remains to be learned about how to make school learning about sexual health influence the real‐life choices of students. In order to provide a more nuanced understanding of young people's decision‐making, this study examines students' talk about sexual health decision‐making through the lens of identities. Qualitative, ethnographic research methods with twenty 12th grade students attending a New York City public school are used to illustrate how students take on multiple identities in relation to sexual health decision‐making. Further, the study illustrates how these identities are formed by various aspects of students' lives, such as school, family, relationships, and religion, and by societal discourses on topics such as gender, individual responsibility, and morality. The study argues that looking at sexual health decision‐making—and at decision‐making about other controversial science topics—as tied to students' identities provides a useful way for teachers and researchers to grasp the complexity of these decisions, as a step toward creating curriculum that influences them. © 2010 Wiley Periodicals, Inc.

Democratizing computer science knowledge: transforming the face of computer science through public high school education

Despite the fact that computer science (CS) is the driver of technological innovations across all disciplines and aspects of our lives, including participatory media, high school CS too commonly fails to incorporate the perspectives and concerns of low-income students of color. This article describes a partnership program – Exploring Computer Science (ECS) – that directly counters this problem in our nation's second largest school district. With a mission of democratizing CS learning, we argue that despite the constraints of working within public schools, it is imperative to do so. We discuss the ECS program based on inquiry, culturally relevant curriculum, and equity-oriented pedagogy. We describe two ECS-affiliated projects that highlight the importance of authorship, purpose, and agency for student learning and engagement: DietSens using mobile technology to study community health, and a project in which students create video games about social issues. Our work offers a counter-narrative to those who have written off the possibilities of working within public schools and a debunking of the too widespread myth within our educational system that females and students of color are inherently uninterested in rigorous CS learning.
