Boundaries and selves in the making of ‘science’

Relying on ideas from practice theory and critical autobiography, I use this article first to tell, and then to analyse, a story about trying to publish a book whose contents are in some ways marginal to what is normally considered science or science education. During the publishing process, what counts as science got tangled up with what counts as “credible” science, “marketable” literature, and academic competence. As a result, a book and a person (me) dedicated to expanding the boundaries of science also became contributors to those very same boundaries.     

Jordanian twelfth-grade science teachers’ self-reported usage of science and engineering practices in the next generation science standards

This study investigated the degree that Science and Engineering Practices (SEPs) criteria from the Next Generation Science Standards (NGSS) were included in self-reported teaching practices of twelfth-grade science teachers in Jordan. This study sampled (n?=?315) science teachers recruited from eight different public school directorates. The sample was surveyed using an instrument adapted from Kawasaki (2015). Results found that Jordanian science teachers incorporate (SEPs) in their classroom teaching at only a moderate level. SEPs applied most frequently included ‘using the diagram, table or graphic through instructions to clarify the subject of a new science,’ and to ‘discuss with the students how to interpret the quantitative data from the experiment or investigation’. The practice with the lowest frequency was ‘teach a lesson on interpreting statistics or quantitative data,’ which was moderately applied. No statistically significant differences at (α?=?0.05) were found among these Jordanian science teachers’ self-estimations of (SEP) application into their own teaching according to the study’s demographic variables (specialisation, educational qualification, teaching experience). However, a statistically significant difference at (α?=?0.05) was found among Jordanian high school science teachers’ practice means based on gender, with female teachers using SEPs at a higher rate than male teachers.     

The dimensions and impact of informal science learning experiences on middle schoolers’ attitudes and abilities in science

Learners encounter science in a wide variety of contexts beyond the science classroom which collectively could be quite influential on student attitudes and abilities. But relatively little is known about the relative influence of different forms of informal science experiences, especially for the kinds of experiences that students typically access. We conduct factor and regression analyses on data collected from a large number of diverse public-school attending 6th and 8th graders drawn from two regions in the USA. Students completed a science reasoning measure and surveys of attitudes, previously completed informal science learning experiences, and demographic factors. Factor analyses identify four dimensions of informal science learning participation (in home, semiformal, nature, and museums). Regression analyses find a relative specificity of effects, with particular outcomes associated with a subset of the forms of informal science participation, highlighting the importance of controlling for correlated factors. There were also a few differences by grade level, with different experiences influencing the development of competency beliefs in science in early vs. late middle schoolers.     

Portrayals of science and scientists,and ‘science for citizenship’

There are increasing calls in the science education community for ‘science for citizenship’ as an important goal for the school science curriculum of the 21st century. The potential influence of portrayals of science and scientists in popular culture on the achievement of this goal is explored in this paper through a review of the literature. We develop a framework of important questions citizens ask in considering personal and social decision making in relation to science and technology issues, and how portrayals of science and scientists might contribute to this decision making process.     

Biopolitics and the ‘subject’ of labor in science education

Viewing science education as a site of biopolitical engagement—intervention into forces that seek to define, control, and exploit life (biopower)—requires that science educators ask after how individuals and populations are governed by technologies of power. In this paper, I argue that microanalyses, the analysis of everyday practices and discourses, are integral to biopolitical engagement, are needed to examine practices that constitute subjectivities and maintain oppressive social conditions. As an example of a microanalysis I will discuss how repetitive close-ended lab/assessment tasks, as well as discourses surrounding careers in science, can work to constitute students as depoliticized, self-investing subjects of human capital. I also explore the relationship between science education, (bio)labor and its relation to biopolitics, which remains an underdeveloped area of science education. This paper, part of my doctoral work, began to take shape in 2011, shortly after the 2008 economic crisis achieved a tiny breached in the thick neoliberal stupor of everyday (educational) life.     

Mathematics and science teachers’ pedagogical orientations and their use of ICT in teaching

The key concern driving policy and community interest in the pedagogical integration of ICT is the premise that ICT is important for bringing changes to classroom teaching and learning, so as to foster the development of students’ 21st century skills. An important concept underpinning the design of the SITES 2006 study is the pedagogical orientation of the teacher, which can be broadly conceptualized as traditionally important or 21 ^st century oriented. The latter can be further differentiated into lifelong learning and connectedness oriented. Indicators were created to measure teachers’ pedagogical orientation based on their espoused curriculum goals, teacher practices and student practices. Results from this study shed light on whether there is evidence that 21st century pedagogy as identified in the literature and in innovative practices can be found more generally in random samples of teachers in countries participating in SITES 2006. Relationship between ICT use and pedagogical practice in mathematics and science classrooms is reported and the associated policy implications are discussed.     

Raising critical issues in the analysis of gender and science in children’s literature

Trevor Owens’ paper provides a critique of the role of gender and authority in selected children’s books that presented biographies of Albert Einstein and Marie Curie. In the context of discussing Trevor’s (2009) article about children’s literature, this forum explores issues related to the (a) representation and construction of gender, science, and childhood in literature for children; (b) the need to consider socio/historical/cultural contexts in analytical and theoretical frameworks; and (c) the importance of fostering critical literacy perspectives in pre- and in-service science teachers and the children whom they teach.     

Raising awareness of uncertainty: A useful addendum to courses in the history and philosophy of science for science teachers?

A brief consideration of the need for courses in the history and philosophy of science (HPS) for science teachers is followed by the development of a suggested addendum. The rationale accepts the developmental argument that a conscious awareness of personal uncertainty of explanation provides the motor of change needed to involve science teachers in thinking critically about the nature of their subject. Following the technique pioneered in a different context by Acredolo and O'Connor (1991), the addendum is developed as a test procedure fostering the expression of uncertainties in relation to important questions about science. Using questions designed to serve our specific purposes, a form of the test is trialled on a small group of science teachers attending courses in a Graduate Certificate in Science Education, and the results used to stimulate and promote their discussion of some critical matters concerning the nature of science.     

Body_machine? Encounters of the human and the mechanical in education,industry and science

This paper unveils the body_machine as a key element of dynamic mental maps that have come to shape both educational praxis and research. It traces and analyses instances in which the human and the mechanical encountered each other in metaphorical, material and visual forms, thereby blurring to some extent the boundaries between them while capturing and mobilising specific forms of knowing and acting. The paper studies, first, how certain ‘orienting frames of reference’ and associated ‘experimental systems’ managed to materialise around the body_machine and penetrate theory and praxis; and, second, what visual and textual sources related to a vocational school may reveal about where and how the body_machine has come to operate in education, industry and science. The paper centres on early twentieth-century photographs and analyses these not only as media presenting, representing and interrogating common thought and practice but also as agents of meaning-making around the body_machine.     

An exploratory study of students’ constructions of gender in science,engineering and technology

Despite an appreciation of the need to increase gender sensitivity and awareness among tertiary students in the field of science, engineering and technology (SET), there is a paucity of research that explores how students in this field construct gender. A greater understanding of such constructions can assist in transforming gender relations and creating a more gender‐sensitive learning environment for SET students. This paper explores SET students’ constructions of gender and the discourses they draw on when constructing female participation in SET. Focus group discussions were conducted with male and female students from an urban South African university. A discourse analysis identified various restrictive discourses that resist female participation in SET and value traditional gender roles for men and women, as well as more marginal voices that support gender equity. The paper concludes with recommendations for interventions aimed at challenging restrictive constructions of gender in higher education.     

Provision of in-service training of mathematics and science teachers in Botswana: teachers’ perspectives

Teaching is a field that is dynamic, with innovations necessitating upgrading of skills and education of teachers for the successful implementation of reforms. The behaviour and attitudes of teachers towards teaching and learning and their knowledge banks are the result of the impact of in-service training. This study investigated the perceptions of mathematics and science teachers in Botswana towards in-service provision by the Department of Mathematics and Science Education In-service Training unit (DMSE-INSET), whose mandate is to improve the quality of teaching by supporting teachers through training programmes that enable them to take ownership of their professional development. Data were collected from a sample of 42 senior Mathematics and Science secondary school teachers, using structured interviews with open-ended questions, which were analyzed qualitatively. The findings show that teachers’ concerns included the lack of impact of current in-service training programmes on the education system, no regular follow-up activities to support the one-off workshops and insufficient skills acquired to sustain the implementation of the strategies solicited by the workshops.     

Sex bias in science teachers’ ratings of work and pupil characteristics‡

In this paper, the role of modelling in the teaching and learning of science is reviewed. In order to represent what is entailed in modelling, a 'model of modelling' framework is proposed. Five phases in moving towards a full capability in modelling are established by a review of the literature: learning models; learning to use models; learning how to revise models; learning to reconstruct models; learning to construct models de novo . In order to identify the knowledge and skills that science teachers think are needed to produce a model successfully, a semi-structured interview study was conducted with 39 Brazilian serving science teachers: 10 teaching at the 'fundamental' level (6-14 years); 10 teaching at the 'medium'-level (15-17 years); 10 undergraduate pre-service 'medium'-level teachers; 9 university teachers of chemistry. Their responses are used to establish what is entailed in implementing the 'model of modelling' framework. The implications for students, teachers, and for teacher education, of moving through the five phases of capability, are discussed.     

Instructional practices and science performance of 10 top-performing regions in PISA 2015

ABSTRACT

This study analysed 10 top-performing regions in PISA 2015 on their science performances and instructional practices. The regions include Singapore, Japan, Estonia, Taipei, Finland, Macao, Canada, Hong Kong, China and Korea. The science performances of the 10 regions and their teaching practices are described and compared. The construct of enquiry-based instruction as developed in PISA 2015 is revised into two new constructs using factor analysis. Then, the relationships of the teaching practices with science performance are analysed using hierarchical linear modelling. Adaptive instruction, teacher-directed instruction and interactive application are found positively associated with performance in all regions, while investigation and perceived feedback are all negative. The regions except Japan and Korea tend to have a high frequency of teacher-directed instruction facilitated by more or less authoritative class discussion in class. A fair amount of practical work is done, but not many of them are investigations. The cultural influences on teaching practices are discussed on how an amalgam of didactic and constructivist pedagogy is created by the Western progressive educational philosophy meeting the Confucian culture. The reasons for investigation’s negative association with performance are also explored.     

Teachers’ practices in science learning environments and their use of formative and summative assessment tasks

This study was aimed at detecting the most frequently-used teaching and assessment activities in secondary school science classes, identifying links between these variables, and revealing possible challenges in these processes. To this end, data were gathered from 155 secondary school science teachers in 56 Israeli public schools and 380 grade eight and nine students from 22 of these using the What Is Happening In this Class? Teachers were also asked to indicate their perceptions of the extent to which they used formative assessment tasks provided by the curriculum and to specify, in their own words, the reason for insufficient usage of these tasks. Task orientation was highly used in science classes, whereas investigation was the least employed activity, according to both teachers’ and students’ perceptions. The most-frequently used tasks to evaluate students were final tests and quizzes. Path model analysis revealed that teachers who tended to use teacher-based approaches also employed traditional assessment tools, whereas teachers who allowed students to cooperate rather than compete with one another tended to use formative assessment tools. Implications limitations, and directions for future research are discussed.     

The interplay of learning approaches and self-efficacy in secondary school students’ academic achievement in science

ABSTRACT

The aim of the present investigation was to analyse the role of academic self-efficacy and approaches to learning in general and in Physics and Chemistry academic achievements. The sample comprised 507 secondary school students of two Spanish schools and the study was conducted in the context of a Physics and Chemistry subject. Structural equation models showed that surface motive was the only type of learning approach directly related to performance. Besides, our models revealed that self-efficacy plays an important role as a mediating variable between the surface strategy and the deep motive learning approaches and academic achievement. Gender effects were also studied as girls showed higher levels of achievement both in general performance and in Physics and Chemistry. Implications for science education and suggestions for future research of these findings are also discussed.     

Students’ conceptions and the learning of science

This introductory article to the Special Issue of the International Journal of Science Education attempts to review the theoretical contexts for research into children's conceptions in science and to identify future directions for research programmes in this field.     

Student‐teachers’ conceptions of science,teaching and learning: a case study in preservice science education

The resort to experiment is considered to be essential for teaching physics. But it often consists of an inductivist method where students are supposed to be able to find physical laws by observing phenomena. In fact it is not as easy for the students as it is for the physicist. We propose and test another way. When studying a new phenomenon, an initial discussion is performed between students in the class. They can propose various (eventually contradictory) explanatory models. Experiments are then used to make a choice between these models. Sequences in class situation are described, with learning behaviour and results reported for pupils in French schools (grades 6 and 8, 11‐14‐year olds).     

Staying in the science stream: patterns of participation in A‐level science subjects in the UK

This paper describes patterns of participation and attainment in A‐level physics, chemistry and biology from 1961 to 2009. The A level has long been seen as an important gateway qualification for higher level study, particularly in the sciences. This long‐term overview examines how recruitment to these three subjects has changed in the context of numerous policies and initiatives that seek to retain more young people in the sciences. The results show that recruitment to the pure sciences has stagnated, general trends have hardly varied and the track record of government policy in influencing change is not strong. There is no evidence for increasing achievement gaps between the sexes at A level and even national policy requiring that all young people study science up to the age of 16 appears to have had little impact on recruitment at this level.
