A Degree Is Not Enough: A quantitative study of aspects of pre-service science teachers’ chemistry content knowledge

Aspects of chemistry content knowledge held by 265 UK-based pre-service teachers (PSTs) were probed using 28 diagnostic questions in five chemistry concept areas, Particle theory and changes of state, Mass conservation (taught to 11–14-year-olds), and Chemical bonding, Mole calculations and Combustion reactions (taught to 14–16-year-olds). Data were collected over six years from academically able science graduates starting a full-time, university-based teacher education programme of one academic year duration. PSTs in three sub-cohorts (‘chemists', ‘physicists' and ‘biologists' on the basis of their undergraduate degrees) demonstrated similar levels of content knowledge (CK) for Particle theory and changes of state and Mass conservation. Biologists demonstrated statistically significantly weaker understanding than chemists and physicists in Chemical bonding, Mole calculations and Combustion reactions. Forty-four ‘triads' each comprising one chemist, physicist and biologist, matched by academic and personal backgrounds, showed that chemists outperformed biologists and physicists in Chemical bonding and Combustion reactions. The findings suggest that non-chemists' CK is insufficient for teaching these chemistry concepts in high schools, despite their possession of ‘good' Bachelor of Science degrees. These data have implications for science teacher education, including how best to prepare science graduates from diverse backgrounds for teaching specialist science subjects to 11–16-year-olds.     

Doctors diagnose,teachers label: the unexpected in pre-service teachers’ talk about labelling children with ADHD

A study in an Australian university investigated 150 pre-service teachers’ responses to and participation in discourses of attention deficit hyperactivity disorder (ADHD). Interesting data surfaced around the notion of ‘labelling’ children with ADHD. It seemed that the pre-service teachers did not believe ‘ADHD’ to be a label. Whilst the literature reviewed acknowledged diagnosing a child with ADHD to be tantamount to labelling (that is, ‘ADHD’ is a medical diagnostic label), the pre-service teachers in this study differentiated diagnosis from labelling and cast labelling as occurring in the classroom sometime pre- or post- diagnosis. Speaking of diagnosis and labelling in this way re-defines an object of dominant labelling discourse: ‘doctor as labeller’ is replaced with notions of ‘teacher as labeller’. Using Foucault’s ‘rules of discursive formations’ to frame its analysis, this study pondered the pre-service teachers’ conceptions of labelling and in doing so revealed a ‘teacher as labeller’ discursive formation. This article provides examples of how this discursive formation features in pre-service teachers’ talk and outlines an important implication of the ‘teacher as labeller’ discursive formation, namely that it enables teachers to cement their role in the ADHD medical diagnostic apparatus.     

Science Teachers and Science‐Related Attitudes

Summaries

English

Science teachers’ perceptions of affective‐domainobjectives were gathered through interview procedures. A sample of teachers in Western Australian high schools were the subjects of the study.

For the purpose of analysis, a distinction is drawn between attitudes to science (such as ‘enjoyment of science lessons’ and ‘interest in science') and scientific attitudes (such as ‘honesty in reporting data’and ‘tolerance of the views of others').

Analysis of teachers’ views revealed confusion and lack of clarity regarding these science‐related attitudes. However, it is argued that curriculum writers are no clearer in their views.

It is suggested that a much clearer, more explicit justification for attitude objectives (of both kinds) needs to be made by curriculum writers. Science teachers need to be provided with greater assistance in clarifying the role of these attitude objectives, as well as assistance with techniques for their assessment.     

‘You Have to Give Them Some Science Facts’: Primary Student Teachers’ Early Negotiations of Teacher Identities in the Intersections of Discourses About Science Teaching and About Primary Teaching

In the broadest sense, the goal for primary science teacher education could be described as preparing these teachers to teach for scientific literacy. Our starting point is that making such science teaching accessible and desirable for future primary science teachers is dependent not only on their science knowledge and self-confidence, but also on a whole range of interrelated sociocultural factors. This paper aims to explore how intersections between different Discourses about primary teaching and about science teaching are evidenced in primary school student teachers’ talk about becoming teachers. The study is founded in a conceptualisation of learning as a process of social participation. The conceptual framework is crafted around two key concepts: Discourse (Gee 2005) and identity (Paechter, Women’s Studies International Forum, 26(1):69–77, 2007). Empirically, the paper utilises semi-structured interviews with 11 primary student teachers enrolled in a 1-year Postgraduate Certificate of Education course. The analysis draws on five previously identified teacher Discourses: ‘Teaching science through inquiry’, ‘Traditional science teacher’, ‘Traditional primary teacher’, ‘Teacher as classroom authority’, and ‘Primary teacher as a role model’ (Danielsson and Warwick, International Journal of Science Education, 2013). It explores how the student teachers, at an early stage in their course, are starting to intersect these Discourses to negotiate their emerging identities as primary science teachers.     

The Commonalities and Dissonances Between High-School Students' and Their Science Teachers' Conceptions of Science Learning and Conceptions of Science Assessment: A Taiwanese sample study

The main purpose of this study was to concurrently investigate Taiwanese high-school students' and their science teachers' conceptions of learning science (COLS) and conceptions of science assessment (COSA). A total of 1,048 Taiwanese high-school students and their 59 science teachers were invited to fill out two questionnaires assessing their COSA and COLS. The main results indicated that, first, although a handful of different patterns occurred, students and teachers were found to have similar COLS–COSA patterns. In general, students and teachers with COSA as reproducing knowledge and rehearsing tended to possess lower-level COLS, such as learning science as memorizing, testing, and calculating and practicing. In contrast, if students and teachers viewed science assessment as improving learning and problem-solving, they would be prone to regard science learning as increase of knowledge, applying, and understanding and seeing in a new way. However, the students' conceptions did not align with those of the teachers' in certain aspects. The students tended to regard science learning and assessment at a superficial level (COLS as ‘memorizing’, ‘testing’, and ‘calculating and practicing’ and COSA as ‘reproducing knowledge’), while the teachers’ conceptions were at a more sophisticated level (COLS as ‘application’ and ‘understanding and seeing in a new way’ and COSA as ‘improving learning’). It is evident that a dissonance exists between the students' and teachers' COLS and COSA. Based on the results, practical implications and suggestions for future research are discussed.     

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.     

Reply to Professors Day and Qing Gu

Science education in the United Kingdom faces a dual challenge in the near future: that of addressing increasing disaffection from the subject by pupils as they enter adolescence coupled with the downturn in learning as they leave primary school behind. Both bridging work and teacher creativity have been identified as key ingredients in ensuring pupil engagement in learning, yet innovation requires both time and a broader vision than may be offered by a normative and centralized pedagogy. This paper proposes a four‐stage model for curriculum development to encourage creativity, based on the experiences of teachers as they designed bridging work for pupils in science. A grounded theory approach is utilized to generate four concept categories emerging from participants' comments during the study. These are described as uncertainty, visioning, realization and readiness, and this research demonstrates that ‘bottom–up’ is a very effective method of professional development promoting combinatorial thinking and creative science teaching.     

A contextual critique of critical literacy: Freirean ‘generative themes’ and their impact on pedagogic practice

Public education in post-industrial societies has been restructured based on a human capital model that prioritizes the economic value of citizens for the benefit of globally competitive national economies. In a policy-as-numbers climate [Lingard, B. (2011). Policy as numbers: Ac/counting for educational research. The Australian Educational Researcher, 38(4), 355–382], school administrators and teachers struggle to ‘produce results’ and ‘close gaps’ within accountability systems built on standardized measures of learning. What possibilities exist for critical literacy as viable classroom pedagogy in such an environment? This article offers a contextual–empirical analysis of efforts to implement critical literacy in mainstream secondary classes in Singapore. Drawing on Freire’s notion of generative themes, it identifies key political-policy constraints, showing how they impacted the pedagogical enactment of critical literacy tenets and pinpointing a focal direction for critical literacy in Singapore’s English education. More generally, the article argues that critical literacy, more than ever, must be a localized practice responding to exigencies emerging at the global–local nexus.     

Developing an instrument for assessing students’ concepts of the nature of technology

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.

Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.

Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.

Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.

Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.

Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion.     

Assessing Students' Understandings of Biological Models and their Use in Science to Evaluate a Theoretical Framework

Research in the field of students’ understandings of models and their use in science describes different frameworks concerning these understandings. Currently, there is no conjoint framework that combines these structures and so far, no investigation has focused on whether it reflects students' understandings sufficiently (empirical evaluation). Therefore, the purpose of this article is to present the results of an empirical evaluation of a conjoint theoretical framework. The theoretical framework integrates relevant research findings and comprises five aspects which are subdivided into three levels each: nature of models, multiple models, purpose of models, testing, and changing models. The study was conducted with a sample of 1,177 seventh to tenth graders (aged 11–19 years) using open-ended items. The data were analysed by identifying students' understandings of models (nature of models and multiple models) and their use in science (purpose of models, testing, and changing models), and comparing as well as assigning them to the content of the theoretical framework. A comprehensive category system of students' understandings was thus developed. Regarding the empirical evaluation, the students' understandings of the nature and the purpose of models were sufficiently described by the theoretical framework. Concerning the understandings of multiple, testing, and changing models, additional initial understandings (only one model possible, no testing of models, and no change of models) need to be considered. This conjoint and now empirically tested framework for students' understandings can provide a common basis for future science education research. Furthermore, evidence-based indications can be provided for teachers and their instructional practice.     

Reading: three to thirteen

Askew and his colleagues (1997), put forward a range of important notions as to what might constitute effective approaches to the teaching of numeracy. In particular, they place great emphasis on the way in which teachers who make links between different areas of mathematics are seen to be effective teachers of numeracy. (Askew et al term this approach ‘connectionist’)

The work reported here suggests that the notion of classifying a teacher as, say, connectionist is too simplistic. We report observations which suggest that effective teachers of numeracy incorporate a range of approaches into their teaching.     

Troubling literacy: monolingual assumptions,multilingual contexts,and language teacher expertise

The current educational context in many English speaking countries is one where literacy is understood to be essentially monolingual in orientation; that is, an understanding of literacy around a single common language, with the emphasis on identifying universal, normative ‘standards’ and ‘benchmarks’, such as the National Assessment Program-Literacy and Numeracy in Australia, the Primary National Strategy in the United Kingdom, and No Child Left Behind in the United States. This paper aims to problematise such assumptions by examining how teachers, themselves, understand “teaching literacy” when their students come to the teaching/learning relationship with a first language other than English. With a focus on teachers working with bilingual and multilingual students in their early stages of acquiring English as a second language (ESL), the study thus acknowledges the increasingly diverse sociolinguistic profile of students in Australia and elsewhere in the varying degrees of communicative competence they bring to the mainstream in their use of ESL. Moreover, it draws on ESL teacher knowledge and expertise which has been identified as increasingly marginalised within mainstream educational discourse. Through case studies of three ESL teachers in the middle years, salient themes around the interrelated notions of literacy as learning, language for literacy and language as literacy were identified with respect to the literacy needs of second language learners.     

Children's Concepts of the Shape and Size of the Earth,Sun and Moon

Children's understandings of the shape and relative sizes of the Earth, Sun and Moon have been extensively researched and in a variety of ways. Much is known about the confusions which arise as young people try to grasp ideas about the world and our neighbouring celestial bodies. Despite this, there remain uncertainties about the conceptual models which young people use and how they theorise in the process of acquiring more scientific conceptions. In this article, the relevant published research is reviewed critically and in-depth in order to frame a series of investigations using semi-structured interviews carried out with 248 participants aged 3–18 years from China and New Zealand. Analysis of qualitative and quantitative data concerning the reasoning of these subjects (involving cognitive categorisations and their rank ordering) confirmed that (a) concepts of Earth shape and size are embedded in a ‘super-concept’ or ‘Earth notion’ embracing ideas of physical shape, ‘ground’ and ‘sky’, habitation of and identity with Earth; (b) conceptual development is similar in cultures where teachers hold a scientific world view and (c) children's concepts of shape and size of the Earth, Sun and Moon can be usefully explored within an ethnological approach using multi-media interviews combined with observational astronomy. For these young people, concepts of the shape and size of the Moon and Sun were closely correlated with their Earth notion concepts and there were few differences between the cultures despite their contrasts. Analysis of the statistical data used Kolmogorov–Smirnov Two-Sample Tests with hypotheses confirmed at K–S alpha level 0.05; r_s : p?<?0.01.     

From Doing to Learning: Changed focus during a pre-school learning study project on organic decomposition

We explored the use of the learning study (LS) model in developing Swedish pre-school science learning. This was done by analysing a 3-cycle LS project implemented to help a group of pre-school teachers (n?=?5) understand their science educational practice, by collaboratively and systematically challenging it. Data consisted of video recordings of 1 screening (n?=?7), 1 initial planning meeting, 3 analysis meetings, 3 interventions, and 78 individual test interviews with the children (n?=?26). The study demonstrated that the teachers were initially uncomfortable with using scientific concepts and with maintaining the children's focus on the object of learning without framing it with play. During the project, we noted a shift in focus towards the object of learning and how to get the children to discern it. As teachers’ awareness changed, enhanced learning was noted among the children. The study suggests that the LS model can promote pre-school science learning as follows: by building on, re-evaluating, and expanding children's experiences; and by helping the teachers focus on and contrast critical aspects of an object of learning, and to reflect on the use of play, imagination, and concepts and on directing the children's focus when doing so. Our research showed that the LS model holds promise to advance pre-school science learning by offering a theoretical tool useable to shift the focus from doing to learning while teaching science using learning activities.     

Provoking contingent moments: Knowledge for ‘powerful teaching’ at the horizon

Background: Teacher knowledge continues to be a topic of debate in Australasia and in other parts of the world. There have been many attempts by mathematics educators and researchers to define the knowledge needed by teachers to teach mathematics effectively. A plethora of terms, such as mathematical content knowledge, pedagogical content knowledge, horizon content knowledge and specialised content knowledge, have been used to describe aspects of such knowledge.

Purpose: This paper proposes a model for teacher knowledge in mathematics that embraces and develops aspects of earlier models. It focuses on the notions of contingent knowledge and the connectedness of ‘big ideas’ of mathematics to enact what is described as ‘powerful teaching’. It involves the teacher’s ability to set up and provoke contingent moments to extend children’s mathematical horizons. The model proposed here considers the various cognitive and affective components and domains that teachers may require to enact ‘powerful teaching’. The intention is to validate the proposed model empirically during a future stage of research.

Sources of evidence: Contingency is described in Rowland’s Knowledge Quartet as the ability to respond to children’s questions, misconceptions and actions and to be able to deviate from a teaching plan as needed. The notion of ‘horizon content knowledge’ (Ball et al.) is a key aspect of the proposed model and has provoked a discussion in this article about students’ mathematical horizons and what these might comprise. Together with a deep mathematical content knowledge and a sensibility for students and their mathematical horizons, these ideas form the foundations of the proposed model.

Main argument: It follows that a deeper level of knowledge might enable a teacher to respond better and to plan and anticipate contingent moments. By taking this further and considering teacher knowledge as ‘dynamic’, this paper suggests that instead of responding to contingent events, ‘powerful teaching’ is about provoking contingent events. This necessarily requires a broad, connected content knowledge based on ‘big mathematical ideas’, a sound knowledge of pedagogies and an understanding of common misconceptions in order to be able to engineer contingent moments.

Conclusions: In order to place genuine problem-solving at the heart of learning, this paper argues for the idea of planning for contingent events, provoking them and ‘setting them up’. The proposed model attempts to represent that process. It is anticipated that the new model will become the framework for an empirical research project, as it undergoes a validation process involving a sample of primary teachers.     

‘The world must stop when I’m talking’: gender and power relations in primary teachers’ classroom talk

The present paper examines male and female teachers’ language practices in relation to ‘censuring’ talk in the primary classroom, in the context of the debate around boys’ ‘underachievement’ and the ‘feminisation’ of primary school culture. Through an analysis of classroom observations with 51 men and women teachers, it looks to see whether gender differences could be found in the ways individual men and women teachers communicated in terms of their ‘censuring’ comments of pupils’ work or behaviour. Secondly, the paper takes issue with the notion that teachers operate within a ‘feminised’ educational culture, by looking at the ways in which teachers’ classroom talk can be seen to be constrained by two contrasting discourses relating to the power relation between teacher and pupil: a ‘traditional’ disciplinarian discourse, and a more ‘progressive’ liberal discourse. Both discourses have complex gendered and class dimensions, challenging the conception of a ‘feminised’ primary school culture.     

What Teachers of Science Need to Know about Models: An overview

The purpose of this article is to provide an overview of the nature of models and their uses in the science classroom based on a theoretical review of literature. The ideas that science philosophers and science education researchers have in common about models and modelling are scrutinised according to five subtopics: meanings of a model, purposes of modelling, multiplicity of scientific models, change in scientific models and uses of models in the science classroom. First, a model can be defined as a representation of a target and serves as a ‘bridge’ connecting a theory and a phenomenon. Second, a model plays the roles of describing, explaining and predicting natural phenomena and communicating scientific ideas to others. Third, multiple models can be developed in science because scientists may have different ideas about what a target looks like and how it works and because there are a variety of semiotic resources available for constructing models. Fourth, scientific models are tested both empirically and conceptually and change along with the process of developing scientific knowledge. Fifth, in the science classroom, not only teachers but also students can take advantage of models as they are engaged in diverse modelling activities. The overview presented in this article can be used to educate science teachers and encourage them to utilise scientific models appropriately in their classrooms.     

Jonathan Livingstone,I Presume: teaching as a ‘high‐flying’ profession

This paper points to a new discursive order in teacher education policy and professional development practice which is actively producing teachers as ‘corporatising’ professionals. The authors note certain rhetoric shifts in Australian teacher education policy which, they argue, constitute quite a radical departure from notions of the professional worker which proliferated less than a decade ago. Drawing on Foucaultian notions of the discursive nature of knowledge and identity formation, they discuss the implications of this rhetorical shift in terms of its impact on the ‘professional’ identity of the teacher.     

Students’ qualification in environmental and sustainability education—epistemic gaps or composites of critical thinking?

In an ‘age of measurement’ where students’ qualification is a hot topic on the political agenda, it is of interest to ask what the function of qualification might implicate in relation to a complex issue as Education for Sustainable Development (ESD) and what function environmental and sustainability issues serve in science education. This paper deals with how secondary and upper secondary teachers in discussions with colleagues articulate qualification in relation to educational aims of ESD. With inspiration from discourse theory, the teachers’ articulations of qualification are analysed and put in relation to other functions of education (qualification, socialisation and subjectification). The results of this study show three discourses of qualification: scientific reasoning, awareness of complexity and to be critical. The discourse of ‘qualification as to be critical’ is articulated as a composite of differing epistemological views. In this discourse, the teachers undulate between rationalistic epistemological views and postmodern views, in a pragmatic way, to articulate a discourse of critical thinking which serves as a reflecting tool to bring about different ways of valuing issues of sustainability, which reformulates ‘matter of facts’ towards ‘matter of concerns’
