What is ‘Agency’? Perspectives in Science Education Research

The contemporary interest in researching student agency in science education reflects concerns about the relevance of schooling and a shift in science education towards understanding learning in science as a complex social activity. The purpose of this article is to identify problems confronting the science education community in the development of this new research agenda and to argue that there is a need for research in science education that attends to agency as a social practice. Despite increasing interest in student agency in educational research, the term ‘agency’ has lacked explicit operationalisation and, across the varied approaches, such as critical ethnography, ethnographies of communication, discourse analysis and symbolic interactionism, there has been a lack of coherence in its research usage. There has also been argument concerning the validity of the use of the term ‘agency’ in science education research. This article attempts to structure the variety of definitions of ‘student agency’ in science education research, identifies problems in the research related to assigning intentionality to research participants and argues that agency is a kind of discursive practice. The article also draws attention to the need for researchers to be explicit in the assumptions they rely upon in their interpretations of social worlds. Drawing upon the discursive turn in the social sciences, a definition of agency is provided, that accommodates the discursive practices of both individuals and the various functional social groups from whose activities classroom practice is constituted. The article contributes to building a focused research agenda concerned with understanding and promoting student agency in science.     

Grappling with ‘Natural Selection’ — Experiences of a Teacher

Since evolution forms the core of modern biology, teaching about natural selection is extremely important as this equips the student to frame the ‘why’ questions properly and, at the same time, sharpens their understanding about a host of issues pertaining to behaviour, diversity and genetics.     

What is a ‘good’ principal? Perspectives of aspiring principals in Singapore

This paper presents the findings of an exploratory research project that examines what aspiring principals in Singapore think a good principal is, based on a framework of personal, interpersonal, and organizational dimensions of school leadership. According to the findings, a good principal has a moral purpose centered on personal values, a humble disposition, and exudes wisdom. He or she exhibits excellent relational skills, engages in people development, and develops trust among staff. He or she also develops a positive school culture for teaching and learning, builds fruitful relationships with stakeholders, and manages complex issues competently. The findings also suggest that the idea of a good principal is more about who the person is and what he or she stands for, rather than what he or she is capable of. Moreover, while Singapore principals are capable of making hard-nosed decisions and delivering results, they are actually motivated by the ideals of education. This study offers some empirical evidence of the attributes of a ‘good’ principal in the Singapore context.     

What is the Meaning of the Physical Magnitude ‘Work’?

Usually, in physics textbooks, the physical magnitude ‘work’ is introduced as the product of a force multiplied by its displacement, in relation to the transfer of energy. In other words, ‘work’ is presented as an internal affair of physics theory, while its relation to the world of experience, that is its empirical meaning, is missing. On the other hand, in the history of its creation, ‘work’ was a concept that had empirical meaning from the start. It was constructed by engineers to measure the work (labor) of motor engines, men, and animals. Very soon however this initial meaning seems to vanish. In this article, it will be looked at how ‘work’ is presented in physics textbooks, what was its initial meaning in the history of its formulation, under what circumstances this initial meaning faded, and how elements from the history of its creation can be used in the classroom to teach it.

‘Time: What is it That it can be Measured?’

Experiments with the simple pendulum are easy, but its motion is nevertheless confounded with simple harmonic motion. However, refined theoretical models of the pendulum can, today, be easily taught using software like CALCODE. Similarly, the cycloidal pendulum is isochronous only in simplified theory. But what are theoretically equal intervals of time? Newton accepted Barrow’s even tenor hypothesis, but conceded that ‘equal motions’ did not exist – the refutability of Newtonian physics is independent of time measurement. However, time measurement was the key difficulty in reconciling Newtonian physics with electrodynamics. On Poincaré’s criterion of convenience, equal intervals of time ought be so defined as to make the enunciation of physics simple. Hence he postulated constancy of the speed of light. (The Michelson–Morley experiment was not critical.) The theory of relativity followed. But does there exist a proper clock?     

Darwin’s Arguments in Favour of Natural Selection and Against Special Creationism

In many places in The Origin of Species, Darwin compares his own theory of Natural Selection favourably with Special Creationism which comes off as a bad second best. He does this using some version of the argument form known as ‘Inference to the Best Explanation’. The first part of this paper is methodological. It considers Whewell’s notion of consilience, that is, the way in which theories can get additional confirmation through unifying otherwise disparate and independent facts. Then it considers various forms of inference to the best explanation. The second part of the paper applies these methodological considerations to an analysis of some of the many passages in Origin where Darwin presents his case in favour of Natural Selection. This gives a far superior explanation of biological facts compared with Special Creationism which provides either an inferior explanation or no explanation at all. Contrary to the view that Creationism should not be taught, the passages from Darwin show at least that it should be understood if only to show that it offers no explanation of a wide range of obvious biological facts. As such the passages in Origin in which Darwin presents his case against Creationism can serve as a series of excellent exercises in getting students to think about Natural Selection as opposed to Creationism. For this reason alone they ought to be better known. In addition, Darwin’s point in these passages can only be understood using principles of scientific method, such as inference to the best explanation, which are essential in showing that Natural Selection is to be preferred to Creationism.     

‘What about us?’ Gypsies,Travellers and ‘White racism’ in secondary schools in England

This article examines the concept of ‘White racism’ in relation to the experiences of Gypsy and Traveller groups in England. It is based on ethnographic research conducted in two secondary schools during the years 2006–2009. Interviews were carried out with pupils attending the secondary schools, their mothers and members of the Traveller Education Service. The research reveals that racism experienced by White Gypsy and Traveller groups is understood differently to that experienced by non-White minority ethnic groups. This is further related to how Gypsy and Traveller groups are perceived inside and outside schools, as ‘others’ and ‘outsiders’. The article considers discourses around racism and discrimination and how they might work to disadvantage Gypsy and Traveller groups in schools.     

What’s in a word? Practices associated with ‘feedforward’ in higher education

Abstract

The term ‘feedforward’ is increasingly employed in higher education, and this paper focuses on the way in which it fits into contemporary debates about feedback and its impact on practitioners. Semi-structured interviews were used to investigate the practices academics associate with feedforward and the ways in which their intentions and understandings varied. The term resulted in practices being framed as a process and prompted academics to consider the points in the future when students were expected to deploy information and improve. Three future horizons were identified: the ‘within-module’ future horizon dominated, while the challenges of ‘beyond-module’ and ‘beyond-programme’ horizons became apparent. Written comments, guidance, formative assessment and design practices were associated with feedforward, comprising both transmission and student-focused approaches. It is concluded that the modular system restricts longer-term future horizons and sustainable practices, and more must be done to address the divide between theoretical and practitioners’ perspectives.     

Opinion: ‘Learning Technologies’? ‘Convergent Technologies’? What Do These Mean?

Sometimes in curriculum development, and everyday usage, a new term, or new piece of jargon, springs into common use, and everyone seems to know what it means, yet no one can give a clear definition of just what it signifies in practical terms. Moreover, being ‘new’, we might reasonably expect that anyone using such a term would also be able to explain how it is different from any older terms, and how the ‘new’ parts of the meaning relate to older meanings. But often the sheer newness of the term is so attractive to those who use it that they do not pause and try to make any sensible connection with earlier ideas. These had once themselves been new, and had been for years taken for granted, yet are now pushed aside without a second thought, largely because the new term arrives with a sense of compelling urgency. Something needs to be done, right now, because, look...we have to deal with this new thing called ‘X’. But what is this ‘X’? And why should we do anything about it? We actually need to begin with some hard critical thinking.     

What is reciprocal understanding in virtual interaction?

The aim of this study is to investigate what is reciprocal understanding in virtual web-based interaction and what does it consist of. The context of this study was an international web-based pre-service teacher education (N=116) course. The study is based on an idea of shared cognition and reciprocal understanding, in particular. It is assumed that reciprocity is an essential component not only of social interaction, but also of successful virtual interaction. Since many kinds of virtual interaction, such as e-learning, web-based courses, and virtual universities are rapidly getting more common in education, there is a need to analyse the issue of reciprocal understanding in web-based learning in order to develop more profound pedagogical models. The results widely show that during this particular web-based course there was reciprocal discussion between the participants. Participants had mutual negotiations and they discussed about issues from a variety of different viewpoints. Seven different ideas were found for the mechanisms of reciprocal understanding. It is concluded that this information is useful for developing a new pedagogical model for web-based learning and enhancing the quality of virtual interaction.     

What Kind of ‘Knowledge’ is English? (Re-reading the Newbolt Report)

This essay takes Michael Young’s 2007 call ‘to bring knowledge back in’ as an occasion to reflect on the relationship between subject English and the disciplinary knowledge that provides its foundations. It focuses on a key text in the history of English teaching, namely The Teaching of English in England, published in 1921 (otherwise known as the Newbolt Report), arguing that it reflects a moment in the emergence of English as a cultural praxis that is still relevant to us, especially with respect to the claims it makes for literature as the core of subject English. The richness of subject English as it is embodied in its history cannot be comprehended by Young’s understanding of ‘knowledge’.     

What is this Substance? What Makes it Different? Mapping Progression in Students’ Assumptions about Chemical Identity

Given the diversity of materials in our surroundings, one should expect scientifically literate citizens to have a basic understanding of the core ideas and practices used to analyze chemical substances. In this article, we use the term ‘chemical identity' to encapsulate the assumptions, knowledge, and practices upon which chemical analysis relies. We conceive chemical identity as a core crosscutting disciplinary concept which can bring coherence and relevance to chemistry curricula at all educational levels, primary through tertiary. Although chemical identity is not a concept explicitly addressed by traditional chemistry curricula, its understanding can be expected to evolve as students are asked to recognize different types of substances and explore their properties. The goal of this contribution is to characterize students' assumptions about factors that determine chemical identity and to map how core assumptions change with training in the discipline. Our work is based on the review and critical analysis of existing research findings on students' alternative conceptions in chemistry education, and historical and philosophical analyses of chemistry. From this perspective, our analysis contributes to the growing body of research in the area of learning progressions. In particular, it reveals areas in which our understanding of students' ideas about chemical identity is quite robust, but also highlights the existence of major knowledge gaps that should be filled in to better foster student understanding. We provide suggestions in this area and discuss implications for the teaching of chemistry.     

What’s involved in ‘the work’? Understanding administrators’ roles in bringing trans-affirming policies into practice

ABSTRACT

Researchers have concluded that policy implementation is a process of mutual adaptation between policies and implementers. Our study draws attention to that relationship, especially with respect to policies that challenge assumptions about sex, gender, and sexuality. We focus on how six administrators in one United States school district understood ‘the work’ of bringing the district’s Guidelines for Supporting Transgender and Gender Nonconforming Students into practice. Our analysis of interview data focused these questions: How do administrators describe their motivation and commitment to engage in the work? What puzzles of practice do participants name? How do they talk about the work of implementation? What does that work mean/involve in everyday practice? What were their roles? We found that implementation was locally defined and enacted; participants’ sense-making, their roles in enacting the Guidelines, and the puzzles they negotiated were influenced by their unique contexts. We share examples of diverse cases in an effort to create policy knowledge.
