Towards a Curricular Model of the Nature of Science

The nature of science is a complex theme, and continues to be the subject of advanced and ongoing scholarship, drawing upon a range of disciplines. Therefore, whatever is presented in school science as being ‘the’ nature of science must at best be a simplification, and so there is a need to form judgements about which simplifications are most appropriate. Effective ‘curricular models’ of science concepts are designed simplifications of scientific models that guide teachers by indicating target knowledge that is deemed appropriate in terms of the prior learning and conceptual development of a group of learners, and which is both ‘intellectually honest’ and a suitable basis for further learning. A similar approach can guide teaching about the nature of science. A consideration of the English National Curriculum offers an example of how aims relating to the teaching of the nature of science may not be realised in the absence of a suitable explicit curricular model to guide teaching.     

‘Am I Like a Scientist?’: Primary children's images of doing science in school

A considerable body of evidence highlights how inquiry-based science can enhance students' epistemic and conceptual understanding of scientific concepts, principles, and theories. However, little is known about how students view themselves as learners of science. In this paper, we explore primary children's images of doing science in school and how they compare themselves with ‘real’ scientists. Data were collected through the use of a questionnaire, drawing activity, and interviews from 161 Grade 4 (ages 9–10) students in Singapore. Results indicate that ‘doing science as conducting hands-on investigations’, ‘doing science as learning from the teacher’, ‘doing science as completing the workbook’, and ‘doing science as a social process’ are the images of learning science in school that most of the students held. In addition, students reported that they need to be well behaved first and foremost, while scientists are more likely to work alone and do things that are dangerous. Moreover, students often viewed themselves as ‘acting like a scientist’ in class, especially when they were doing experiments. Nevertheless, some students reported that they were unlike a scientist because they believed that scientists work alone with dangerous experiments and do not need to listen to the teacher and complete the workbook. These research findings further confirm the earlier argument that young children can make distinctions between school science and ‘real’ science. This study suggests that the teaching of science as inquiry and by inquiry will shape how students view their classroom experiences and their attitudes towards science.     

The ‘nature of science’ in the school curriculum: the great survivor

This paper explores the ways in which the ‘nature of science’ (NoS) has been interpreted, accommodated and justified within school curricula since science was first schooled in the mid-nineteenth century. It explores how different interpretations of ‘the NoS’ have been invoked by those seeking to reform school science education in response to wider political, economic or social concerns such as the demand to ‘humanise’ school science teaching, to increase the supply of qualified scientists or to promote scientific literacy. It offers some comments upon the implications of these interpretations for current attempts to promote the ‘NoS’ in school science education. The focus of attention is England and, to a lesser extent, the USA but the issues raised are of contemporary relevance to many other parts of the world.     

Knowing and Learning about Science in Primary School ‘Communities of Science Practice’: The Views of Participating Scientists in the MyScience Initiative

MyScience is a primary science education initiative in which being in a community of practice is integral to the learning process. One component of this initiative involves professional scientists interacting with primary school communities which are navigating their way towards sustainable ‘communities of practice’ around the ‘domain’ of ‘investigating scientifically’. This paper describes the ongoing journey to date of eleven scientists (six astronomers and five engineers) who actively participated in MyScience over an extended period. Their views of interactions with teachers and students were analysed using attributes associated with both ‘communities of practice’ and the ‘nature of science’. Findings reveal new understandings about the evolving characteristics associated with the development of such school-community collaborations as well as affordances and barriers that may influence their further growth. The influence of these scientists’ own ‘community of science practices’ may account for some of the findings. Implications for science teaching and learning in primary school community of practice settings are discussed.     

Students' Meaning‐making of Socio‐scientific Issues in Computer Mediated Settings: Exploring learning through interaction trajectories

This article reports on a study concerning secondary school students’ meaning‐making of socio‐scientific issues in Information and Communication Technology‐mediated settings. Our theoretical argument has as its point of departure the analytical distinction between ‘doing science’ and ‘doing school,’ as two different forms of classroom activity. In the study we conducted an analysis of students working with web‐based groupware systems concerned with genetics. The analysis identified how the students oriented their accounts of scientific concepts and how they attempted to understand the socio‐scientific task in different ways. Their orientations were directed towards finding scientific explanations, towards exploring the ethical and social consequences, and towards ‘fact‐finding.’ The students’ different orientations seemed to contribute to an ambivalent tension, which, on the one hand, was productive because it urged them into ongoing discussions and explicit meaning‐making. On the other hand, however, the tension elucidated how complex and challenging collaborative learning situations can be. Our findings suggest that in order to obtain a deeper understanding of students’ meaning‐making of socio‐scientific issues in Information and Communication Technology‐mediated settings, it is important not only to address how students perform the activity of ‘doing science.’ It is equally important to be sensitive with respect to how students orient their talk and activity towards more or less explicit values, demands, and expectations embedded in the educational setting. In other words, how students perform the activity of ‘doing school.’     

A typology of approaches to science teaching in schools

Bentley and Watts (1986) have recently argued that fundamental changes in science are necessary if girls’ needs and expectations in school science are to be met. They explore the implications of a radical shift, from a masculine to a feminist view of science, in terms of the context and conduct of school science, and warrant their attempt to reconstruct a feminist science largely by reference to ‘new paradigm’ research in the social sciences. By exploring the reasons underlying the adoption of ‘new paradigm’ methods in the social sciences, I argue that their explication of a feminist science lacks an important feature that would hinder its consideration as an alternative vision of scientific inquiry and as a basis for changing the content of science curriculum in schools. I further question their need to look to the social sciences as a model, when many social scientists have turned to the physical sciences for inspiration in attempting to reconstruct their own disciplines. By exploring the tenets most commonly held in present‐day science and examining the nature of scientific understanding, I argue that their view of ‘normal’ science is a highly simplified and incomplete stereotype of scientific inquiry. It is suggested that the nature of science is not the root problem, as Bentley and Watts would have us believe.     

Powerful pedagogical strategies in initial teacher education

The development of beginning teachers’ practice during a school placement is a multiplicity of mediated interaction between university and school based systems. Both systems have the common aim of training effective teachers. However day‐to‐day internal institution matters can cause tension between the learning goals set out for the beginning teacher by the university and the schools’ drive to ensure maximum student performance in ‘high stake’ national tests. The aim of the intervention was to set up structures which might enable beginning teachers to develop the capacity to think about and reflect explicitly on their practice, through purposive activity in an authentic classroom environment. The context of the activity was a secondary science course which aimed to encourage new teachers to empathize with secondary school pupils (aged 11–16) and understand their conceptual difficulties in learning about science within the constraints of a ‘curriculum delivery’ lead culture. The dialogue engaged in as part of the intervention helped beginning teachers to think critically about practice during school placements.     

Toward a dialectical notion and praxis of scientific literacy

Received conceptualizations of scientific literacy are grounded in (1) the notions of ‘knowledge’, ‘concepts’, and ‘skills’ that science students have to ‘acquire’, ‘appropriate’, or ‘construct’ or (2) the notion of ‘practices’ to which they have to be ‘enculturated’ so that they become part of a ‘community of practice’. All such notions articulate scientific literacy in a static form, which does not correspond to the dynamic nature of the literacies that can be observed in society. This study proposes a dialectical notion of scientific literacy, which makes thematic its nature as a situated, distributed, collective, emergent, indeterminate, and contingent process. It articulates the idea that knowing a (scientific) language is indistinguishable from knowing one's way around the world. As a consequence, the goal of science education can no longer be to make individual students exhibit particular forms of knowledge but to provide them with contexts in which it is more important to deal with, select, and negotiate different forms of expertise and knowledgeability. This leads one to think of science education as but a part of a democratic liberal education that allows students to become competent to participate in any conversation that includes others with different forms and levels of expertise than their own.     

Imagining the World: The Significance of Religious Worldviews for Science Education

This article begins by examining whether ‘science’ and ‘religion’ can better be seen as distinct or related worldviews, focusing particularly on scientific and religious understandings of biodiversity. I then explore how people can see the natural world, depending on their worldview, by looking at two contrasting treatments of penguin behaviour, namely that provided in the film March of the Penguins and in the children’s book And Tango Makes Three. I end by drawing some initial conclusions as to what might and what might not be included about religion in school science lessons. Science educators and teachers need to take account of religious worldviews if some students are better to understand the compass of scientific thinking and some of science’s key conclusions. It is perfectly possible for a science teacher to be respectful of the worldviews that students occupy, even if these are scientifically limited, while clearly and non-apologetically helping them to understand the scientific worldview on a particular issue.     

Korean Students' Perceptions of Scientific Practices and Understanding of Nature of Science

Korean students have shown relatively little interest and confidence in learning science, despite being ranked in the top percentile in international evaluations of academic achievement in science such as the Trends in International Mathematics and Science Study. Although research indicates a positive relationship between student perceptions of science and their science learning, this area has not been sufficiently explored in Korea. Particularly, even though both students' perceptions of scientific practice and their understanding of the nature of science (NOS) are influenced by their science learning experiences at schools, little research examines how this perception, understanding, and experience are related to one another. This study aimed to uncover Korean students' perceptions of school scientific practice through exploring their drawings, writings, and responses to questionnaires. Participants were 500 Korean students in 3rd, 7th, and 10th grades who were asked to complete an open-ended questionnaire. The results indicated that Korean students typically viewed school scientific practices as experimental activities or listening to lecture; and that most participants held an insufficient understanding of the NOS. Overall, no significant relationship emerged between students' perceptions of school scientific practice and their understanding of the NOS. Our findings highlight the need to help both teachers and students understand the potential breadth of school scientific practices, beyond simple ‘activity mania.’ This study also suggests that teachers must balance implicit and explicit instructional approaches to teaching about the NOS through scientific practices in school science contexts.     

The Uses of the Term Hypothesis and the Inquiry Emphasis Conflation in Science Teacher Education

This paper examines the use and role of the term ‘hypothesis’ in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well‐known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective on language and learning, introducing the notion of pivot terms to operationalise language use as a habit and mediated action. We describe three different customs of using the term ‘hypothesis’ within four cultural institutions that can be said to constitute science teacher education in Sweden. Students were found to habitually use the term hypothesis as meaning a guess about an outcome. This is contrasted to the function of this term in scientific research as a tentative explanation. We also found differences in how this term was used between the pure science courses given by the science departments of universities and science education courses taken only by teacher students. Findings also included further support for school students hypothesis fear reported in an earlier study. It is discussed how these findings can obstruct learning and teaching about the nature of scientific inquiry. Constructivist theories of learning are suggested as a possible origin of these problems. The findings are also related to curricular reform and development.     

When the black box springs open: practical work in schools and the nature of science

The aim of this paper is not to bury practical work in school science but to (once again) reconsider it. We draw on three main areas of discussion: accounts of science and ‘school science work'; teachers and others’ views of the nature of science; and our own data on teachers’ reactions to ‘critical incidents’ and practicals which go wrong. We use this as a basis for re‐thinking the role of practicals. An account of practical work is suggested which has as its main feature diversity rather than a single model or template. Within this diversity we believe that teachers should be open and honest with pupils about which type of practical work they are doing and why. We advocate that students should be made aware of the different kinds of practical work they do and the purposes of this practical work. In short, teachers should explain to students what type of practical work they are doing and why. Our second message is that teachers’ views about the nature of science both inform and are informed by their classroom practices and experiences‐‐especially during lab‐work. To encourage, promote and support critical reflection of these classroom practices and experiences is therefore a vital part of teacher professional development; this in time will promote science curriculum development.     

Teaching the Nature of Science in Physics Courses: The Contribution of Classroom Historical Inquiries

Physics and chemistry programs at the secondary school level in France recommend introducing components of the history of science (HS). Emphasis is placed on a ‘cultural’ dimension, which is poorly defined but essentially refers to elements of epistemological nature. Moreover, the few examples of activities based on HS suggested by the programs and science textbooks are means to learn scientific content and convey a reductive and false image of the nature of science (NoS). Our main issue is to examine the possibility to communicate a more authentic image of NoS with HS. We begin by demonstrating how our historical and epistemological analysis led us to distinguish different learning goals about NoS. We then show how these goals can generate classroom activities involving collective inquiry based on the implementation of documents. These documents may or may not be paired with experiments. Finally, we discuss the tensions that our choices created with science curricula and among teachers.     

Community leaders' views of the purposes of science in the compulsory years of schooling

Accepting that scientific literacy is the primary purpose of science in the compulsory years of schooling leads to the question ‘What does scientific literacy mean in a particular community?’ This paper reports a study designed to provide some insight into that question. Data were gathered through interviews with a sample of community leaders, in the state of Victoria, Australia, about their views of the purposes of school science.

The data reveal that, although most of those interviewed had no formal post‐school science education, their life experiences provided them with useful insights into the question raised. The wisdom of such people could make an important contribution during the initial stages of curriculum development in science.

As people successful in their own fields, the study participants were lifelong learners. Consequently, their responses suggest that a primary focus of school science must be to provide students with a framework that will enable them to continue learning beyond schooling. This is not just a matter of knowledge or skills, but of feeling comfortable with science.

The methods used provide a useful example of how views about education can be gathered from thoughtful, non‐expert community members. In this instance, they allowed a reconceptualization of the purposes of school science. These community leaders argued for an education for ‘science in life’ rather than an education about science.     

From the general to the situated: three decades of metacognition

This paper discusses the notion of metacognition, which is usually defined as ‘cognitions about cognitions’, or ‘thinking about one's own thinking’. In so doing, it reviews the literature on metacognition over the past three decades, listing different definitions of the term and identifying diverse origins of processes metacognitive. Aspects of the nature of metacognition are discussed, highlighting some of its important yet problematic dimensions, and the potentially positive impact metacognition can have on the learning process is addressed. The paper also relates metacognition to the broader area of general thinking skills and discusses the appropriateness of practising metacognition with primary school children. The paper concludes with a synopsis of research in the outcomes of metacognition, in general, and in science education, in particular, highlighting recent interest in blending metacognitive thinking with science subject matter. Directions for research in science education with an interest in metacognition are also proposed.     

Risk and school science education

In this paper I consider a role for risk understanding in school science education. Grounds for this role are described in terms of current sociological analyses of the contemporary world as a ‘risk society’ and recent public understanding of science studies where science and risk are concerns commonly linked within the wider community. These concerns connect with support amongst many science educators for the goal of science education for citizenship. From this perspective scientific literacy for decision making on contemporary socioscientific issues is central. I argue that in such decision making, risk understanding has an important role to play. I examine some of the challenges its inclusion in school science presents to science teachers, review previous writing about risk in the science education literature and consider how knowledge about risk might be addressed in school science. I also outline the varying conceptions of risk and suggest some future research directions that would support the inclusion of risk in classroom discussions of socioscientific issues.     

‘Unthinkable’ Selves: Identity boundary work in a summer field ecology enrichment program for diverse youth

The historical under-representation of diverse youth in environmental science education is inextricably connected to access and identity-related issues. Many diverse youth with limited previous experience to the outdoors as a source for learning and/or leisure may consider environmental science as ‘unthinkable’. This is an ethnographic study of 16 diverse high school youths’ participation, none of who initially fashioned themselves as ‘outdoorsy’ or ‘animal people’, in a four-week summer enrichment program focused on herpetology (study of reptiles and amphibians). To function as ‘good’ participants, youth acted in ways that placed them well outside their comfort zones, which we labeled as identity boundary work. Results highlight the following cultural tools, norms, and practices that enabled youths’ identity boundary work: (1) boundary objects (tools regularly used in the program that facilitated youths’ engagement with animals and nature and helped them work through fear or discomfort); (2) time and space (responsive, to enable adaptation to new environments, organisms, and scientific field techniques); (3) social support and collective agency; and (4) scientific and anecdotal knowledge and skills. Findings suggest challenges to commonly held beliefs about equitable pedagogy, which assumes that scientific practices must be thinkable and/or relevant before youth engage meaningfully. Further, findings illustrate the ways that fear, in small doses and handled with empathy, may become a resource for youths’ connections to animals, nature, and science. Finally, we propose that youths’ situated identity boundary work in the program may have the potential to spark more sustained identity work, given additional experiences and support.     

The Relationship between Students’ Views of the Nature of Science and their Views of the Nature of Scientific Measurement

The present study explores the relationship between students’ views of the nature of science (NOS) and their views of the nature of scientific measurement. A questionnaire with two‐tier diagnostic multiple‐choice items on both the NOS and measurement was administered to 179 first‐year physics students with diverse school experiences. Students’ views on the NOS were classified into four NOS ‘profiles’, and views on measurement were classified according to either the point or set paradigms. The findings show that students with a NOS profile dominated by a belief that the laws of nature are to be discovered by scientists are more likely to have a view of the nature of scientific measurement characterised by a belief in ‘true’ values. On the other hand, students who believe that scientific theories are inventions of scientists, constructed from observations that are then validated through further experimentation, are more likely to have a view of the nature of scientific measurement that is underpinned by the uncertain nature of scientific evidence. The implications for teaching scientific measurement at tertiary level are discussed.     

A Reflection on Some Meanings of ‘Interdisciplinarity’ and ‘Integration Among the Sciences’

Summaries

English

‘Integrated science’ as an aspect of curriculum development is now well established world‐wide and has become the subject of international meetings. This article tries to put forward for discussion some ideas about the meaning of integration among the sciences.

Integration is first discussed in its relation to common culture and disciplinary knowledge. Disciplinarity, recognized as the way in which scientific knowledge has been organized, is seen as the only real possibility for the growth of knowledge. To understand the meanings and the importance of different disciplinary fields, is a didactical objective to be reached through an articulated educational process starting in the primary school. However, another objective of the same importance is the development of the capacity to recognize and utilize disciplinary knowledge for the solution of ‘real’ problems.

In this perspective, an important problem for educational research is the definition of a ‘scientific knowledge for all’ which should enable people to confront real problems with a knowledge of the meanings of science, and of where to find and how to use scientific information.     

A ‘Semantic’ View of Scientific Models for Science Education

In this paper I inspect a ‘semantic’ view of scientific models taken from contemporary philosophy of science—I draw upon the so-called ‘semanticist family’, which frontally challenges the received, syntactic conception of scientific theories. I argue that a semantic view may be of use both for science education in the classrooms of all educational levels, and for research and innovation within the discipline of didactics of science. I explore and characterise a model-based account of the nature of science, and derive some implications that may be of interest for our community.
