Powerful knowledge,esoteric knowledge,curriculum knowledge

This paper seeks to introduce a wider audience to a set of ideas developed by a group of sociologists of education who draw on Basil Bernstein’s late work on knowledge structures and whose epistemological stance is grounded in Social Realism. The paper’s main substantive focus is the concept of ‘powerful knowledge’ – recently popularised by Michael Young – and the implications of this notion for curriculum change. ‘Powerful knowledge’ connects with two other key ideas – ‘knowledge of the powerful’ and ‘esoteric knowledge’ – all of which have fed into recent debates about curriculum development and change. Various inter-connections between these ideas are examined. The paper concludes by identifying three chronic ‘tensions’ which impede efforts to extend powerful knowledge to socially and economically disadvantaged students.     

Student Engagement with Artefacts and Scientific Ideas in a Laboratory and a Concept-Mapping Activity

The purpose of this study is to use a comparative approach to scrutinize the common assumption that certain school science activities are theoretical and therefore particularly suited for engaging students with scientific ideas, whereas others are practical and, thus, not equally conducive to engagement with scientific ideas. We compared two school science activities, one (laboratory work) that is commonly regarded as focusing attention on artefacts that may distract students from central science concepts and the other (concept mapping) that is thought to make students focus directly on these concepts. We observed students in either a laboratory activity about real galvanic cells or a concept-mapping activity about idealized galvanic cells. We used a practical epistemology analysis to compare the two activities regarding students' actions towards scientific ideas and artefacts. The comparison revealed that the two activities, despite their alleged differences along the theory–practice scale, primarily resulted in similar student actions. For instance, in both activities, students interacted extensively with artefacts and, to a lesser extent, with scientific ideas. However, only occasionally did students establish any explicit continuity between artefacts and scientific ideas. The findings indicate that some of the problems commonly considered to be unique for school science practical work may indeed be a feature of school science activities more generally.     

Understanding the world today: the roles of knowledge and knowing in higher education

ABSTRACT

This article argues that knowledge is not a passive product of learning that can be possessed, but rather that it represents an active engagement with ideas, arguments and the world in which they reside. This engagement requires a state of ‘knowing’ – a complex, integrative, reciprocal process that unites the knower with the to-be-known. Exploring the notion of knowledge, this paper considers the roles of truth and belief in knowledge production, the relationship between knowledge and the disciplines, and knowledge as a social and cultural product. These ideas are contextualized in higher education practice with an example of a course designed to help science and engineering students develop criticality and a sense of ‘knowing’ about the world. The students are challenged to consider what it requires to turn facts and information into knowledge, and to unite their knowing with their own personal experiences and ideas about the world.     

Minority Preservice Teachers’ Conceptions of Teaching Science: Sources of Science Teaching Strategies

This study explores five minority preservice teachers’ conceptions of teaching science and identifies the sources of their strategies for helping students learn science. Perspectives from the literature on conceptions of teaching science and on the role constructs used to describe and distinguish minority preservice teachers from their mainstream White peers served as the framework to identify minority preservice teachers’ instructional ideas, meanings, and actions for teaching science. Data included drawings, narratives, observations and self-review reports of microteaching, and interviews. A thematic analysis of data revealed that the minority preservice teachers’ conceptions of teaching science were a specific set of beliefs-driven instructional ideas about how science content is linked to home experiences, students’ ideas, hands-on activities, about how science teaching must include group work and not be based solely on textbooks, and about how learning science involves the concept of all students can learn science, and acknowledging and respecting students’ ideas about science. Implications for teacher educators include the need to establish supportive environments within methods courses for minority preservice teachers to express their K-12 experiences and acknowledge and examine how these experiences shape their conceptions of teaching science, and to recognize that minority preservice teachers’ conceptions of teaching science reveal the multiple ways through which they see and envision science instruction.     

The Rationale for a Teaching Innovation About the Interrelationship Between Science and Technology

This paper refers to the development of a teaching innovation for the nature of science (NOS), for students aged 11–15, which specifically focuses on the interrelationship between science and technology. The development of the teaching and learning materials relied on inputs from three sources: the history and philosophy of science and technology, existing knowledge concerning the teaching and learning about the NOS, empirical data on students’ initial ideas and difficulties about this topic. The first served to provide an account for the various forms of interaction between science and technology, which, in turn, guided the formulation of epistemologically coherent learning objectives. The second provided the pedagogical grounds on which to base the design of the activities. The third facilitated the design of activities that build on students’ productive initial ideas, while providing them with guidance to resolve the difficulties they tend to encounter. In this paper, we describe the rationale underlying the teaching and learning materials and we describe the activity sequence they embody.     

Enhancing Science Literacy for All Students With Embedded Reading Instruction and Writing-to-Learn Activities

Reading and writing in science have been frequently maligned but infrequently studied since the 1960s move toward hands-on science. Current interest in the printed-based language arts in science is supported by contemporary educational reforms and the realization that simply doing more hands-on activities may not improve meaningful learning. Students need opportunities to consolidate their science experiences and to contrast their understandings with the interpretations of the science establishment. Science literacy means that students learn about the "big" ideas of science and how to inform and persuade others about these ideas. This article attempts to sketch a substantive framework for using science reading and science writing with deaf students based on research and informed practice with hearing students.     

Typical Didactical Activities in the Greek Early‐Years Science Classroom: Do they promote science learning?

This paper presents an epistemological analysis of typical didactical activities noted in early‐years science lessons, which was carried out in an attempt to diagnose the extent to which the teaching practices adopted by early‐years educators are successful in supporting young children’s understanding in science. The analysis of didactical activities used a framework that allowed us to discover whether they promoted desired connections between theoretical ideas, evidence and the material world. Theoretical ideas, evidence and the material world are entities internal to scientific inquiry and, in educational contexts, connections between them are considered essential in assisting the development of young children’s scientific thinking. The results indicated that in the early‐years science classroom scientific activity was mainly confined to the representational level. Intervention practices into the material world were limited, and were based on collected evidence. No interventions based on ideas were identified in the science lessons. Missing links between evidence and theory and between ideas and the material world suggest that the didactical activities analysed did not promote scientific understanding.     

The reading–science learning–writing connection: Breakthroughs,barriers, and promises

This article establishes a broad framework from which to interpret and evaluate the reading–science learning–writing connection. The presentation of breakthroughs, barriers, and promises is intended to outline the established links between, to identify current bottlenecks in thinking about, and to highlight productive inquiries into, print-based languages and scientific understanding. The ideas presented come from various disciplines connected to science education. The ideas are meant to be informative, provocative, integrative, supportive, and without hidden agenda.     

“It’s Funny that We Don’t See the Similarities when that’s what We’re Aiming for”—Visualizing and Challenging Teachers’ Stereotypes of Gender and Science

This study illuminates teachers’ conceptions of gender and science and possibilities to challenge these conceptions. Since 2005, a group of teachers (K-6) in Sweden have met approximately once a month in two-hour seminars to discuss and develop their instruction in science and technology based on a gender perspective. The present data consist mainly of audio-recordings of the teacher seminars and video-recordings of science activities with students. Analysis of the empirical data has been carried out in several stages and was inspired by thematic analysis, the theoretical framework of which is based on Hirdman’s and Beauvoir’s theories of gender. The results show that the teachers’ ideas about gender/equity and science exist on several levels, within which various conceptions are represented. On the one hand, “reasoning around similarity”, where teachers consider that both girls and boys should have the same prerequisites for working with science. In contrast, stereotypical conceptions of girls and boys occur when the teachers evaluate their activities with students, and condescending attitudes toward girls are also observed. The girls’ ways of working with science are not as highly valued as the boys’, and this outlook on children can ultimately have consequences for girls’ attitudes towards the subject. When teachers are allowed to read their own statements about the girls, they get “a glimpse of themselves”, and their condescending ideas about girls are made visible. In this way, the teachers can begin their active work towards change, which may lead to new outlooks on and attitudes towards students.     

Teaching for Creativity by Science Teachers in Grades 5–10

This classroom observation study explored how science teachers (N = 22) teach for creativity in grades 5–10 in Oman. We designed an observation form with 4 main categories that targeted the instructional practices related to teaching for creativity: questioning strategy, teacher’s responses to students’ ideas, classroom activities to support creativity, and whole-lesson methods that foster creativity. An open-ended survey was also designed to explore participants’ justifications for their instructional decisions and practices. The findings indicate that the overall level of teaching for creativity was low and that participants’ performance was the highest for teacher’s responses to students’ ideas category and the lowest for classroom activities to support creativity category. We observed that a teacher-centered approach with instructional practices geared toward preparing students for examinations was dominant and that these science teachers were bound to the textbook, following cookbook-style activities. Participants believed that they did not have enough time to cover the content and teach for creativity and that they were not prepared to teach for creativity. Based on these findings, we recommend that programs be developed to prepare science teachers to teach for creativity.

Principal Leadership for Technology-enhanced Learning in Science

Reforms such as technology-enhanced instruction require principal leadership. Yet, many principals report that they need help to guide implementation of science and technology reforms. We identify strategies for helping principals provide this leadership. A two-phase design is employed. In the first phase we elicit principals’ varied ideas about the Technology-enhanced Learning in Science (TELS) curriculum materials being implemented by teachers in their schools, and in the second phase we engage principals in a leadership workshop designed based on the ideas they generated. Analysis uses an emergent coding scheme to categorize principals’ ideas, and a knowledge integration framework to capture the development of these ideas. The analysis suggests that principals frame their thinking about the implementation of TELS in terms of: principal leadership, curriculum, educational policy, teacher learning, student outcomes and financial resources. They seek to improve their own knowledge to support this reform. The principals organize their ideas around individual school goals and current political issues. Principals prefer professional development activities that engage them in reviewing curricula and student work with other principals. Based on the analysis, this study offers guidelines for creating learning opportunities that enhance principals’ leadership abilities in technology and science reform.     

Ways of knowing,outcomes and ‘comparative education’: be careful what you pray for

Comparative education as a field of study in universities (and ‘comparative education’ as practised by nineteenth-century administrators of education in Canada, England, France and the USA) has always addressed the theme of ‘transfer’: that is, the movement of educational ideas, principles and practices, and institutions and policies from one place to another. The first very explicit statement of this way of thinking about ‘comparative education’ was offered in the early nineteenth century in France and was expressed in terms of the expectation that if comparative education used carefully collected data, it would become a science. Clearly – about 200 years later – a large number of systems of testing and ranking, based on the careful measurement of educational processes and product, have provided us with hard data and these data are being used within the expectation that successful transfer (of educational principles and policies and practices from one place to another) can now take place. A transferable technology exists. This article argues that this view – that ‘we’ now have a successful science of transfer – ignores almost all of the complex thinking in the field of ‘academic comparative education’ of the last 100 years; and that it is likely to take another couple of hundred years before it can approximate to being a science of successful social and educational predictions. However, what shapes the article is not this argument per se, but trying to see the ways in which the epistemology of the field of study (academic comparative education) is always embedded in the politics of both domestic educational reform and international political relations – to the point where research in the field, manifestly increasingly ‘objective’ is also de facto increasingly ‘political’. The article is about the ‘how’ and ‘why’ of that and what has been forgotten and what has not yet been noticed.

One course is not enough: Preservice elementary teachers' retention of improved views of nature of science

This study examined the views, and the retention of these views, of 19 preservice elementary teachers as they learned about nature of science (NOS). The preservice teachers participated in a cohort group as they took a science methods course during which they received explicit reflective instruction in nature of science. Through Views of Nature of Science version B (VNOS‐B) surveys and interviews it was found that most preservice teachers held inadequate ideas of nature of science prior to instruction, but improved their views after one semester of instruction in the science methods course. However, 5 months after instruction, the graduate preservice teachers were again interviewed and it was found that several of the students reverted back to their earlier views. The results are interpreted through Perry's scheme, and implications and recommendations for elementary science teacher education are made. © 2005 Wiley Periodicals, Inc.

The Great evolution trial: Use of role-play in the classroom

This article gives both the pedagogic and scientific thinking that guided the construction of a classroom role-play—The Great Evolution Debate. This role-play is about the publication of Darwin's The Origin of Species, which is supposed to be on trial for blasphemy. Historical characters are used to show the range of ideas which were current at that time. The literature on learning history, and on learning about the nature of science, is discussed, leading to an examination of historical empathy as a classroom objective. The reasons for including the various characters in the role-play are explained. The exercise has been used by 15 to 16-year-old students in British high schools with considerable success, and some tentative findings about learning from role-play are drawn from its observation.     

Pupils' understanding of combustion

A questionnaire survey of 300, 14 and 15 year-old pupils in England and Spain was carried out to investigate pupils' general ideas about the process of buring and their ideas about specific types of combustion, using open-ended and structured response questions. Pupils' responses were analysed and categories were defined from a classification scheme previously reported by Andersson (1990). A possible model for progression of pupils' ideas about combustion is discussed. Specialization: science teacher education. Specializations: Problem-solving, pupils' alternative concepts, initial teacher education. Specializations: Environmental education, science teacher development (international).     

Negotiation,embeddedness, and non-threatening learning environments as themes of science and language convergence for English language learners

In this review, we explore the notion of teaching science to English language learners (ELLs) as a balancing act between simultaneously focusing on language and content development, on the one hand, and between structuring instruction and focusing on student learning processes, on the other hand. This exploration is conducted through the lens of a theoretical framework embedded in the Science Writing Heuristic approach, an approach exemplifying immersive orientation to argument-based inquiry. Three learning processes (learning through the language of science, learning about the language of science and living the language of science) and three classroom structures (collective zone of proximal development, symmetric power and trust relationships and teacher as decision-maker) are explored in relation to learning theories and empirical findings from second language acquisition and science, multicultural and teacher education bodies of work. Three themes – negotiation, embeddedness and non-threatening learning environments – to inform ELL science education emerged from the review.     

The Large Context Problem (LCP) Approach

This article traces the development of a contextual approach to the teaching of science (physics) subsequently called the Large Context Problem (LCP) approach. This approach is based on the general observation that learning could be well motivated by a context with one unifying central idea capable of capturing the imagination of the students. The design and the placing of the LCP is followed by a detailed discussion of the contexts of inquiry (as we find it in Newtonian physics) that attempts to give the contextual activities found in the LCP a sound theoretical backing. However, the contextual base must also be informed by the findings of constructivist learning theories as well as the history of science. Moreover, thought experiments (TEs) are considered an important aspect of science (physics) teaching and three kinds of TEs are discussed. All these ideas are summarized for a quick overview in a table called “Levels of investigation for scientific inquiry.”
