Scepticism and doubt in science and science education: the complexity of global warming as a socio-scientific issue

This article looks critically at the complexity of the debate among climate scientists; the controversies in the science of global temperature measurement; and at the role played by consensus. It highlights the conflicting perspectives figuring in the mass media concerned with climate change, arguing that science teachers should be familiar with them, particularly given the sharply contested views likely to be brought into classroom discussion and the importance of developing intellectual scepticism and robust scientific literacy in students. We distinguish between rational scepticism and the pejorative meaning of the expression associated with attitudinal opposition to global warming—similar to the way in which Bauer (2006) contrasts micro-scepticism and macro-scepticism in reasoning generally. And we look closely and critically at the approaches which teachers might adopt in practice to teach about global warming at this difficult time.     

Beyond evidence: a critical appraisal of global warming as a socio-scientific issue and a reflection on the changing nature of scientific literacy in school

Tom G. K. Bryce and Stephen P. Day’s (2013) original article on scepticism and doubt in science education explores the context of citizens’ attitudes towards the complexities and uncertainties of global issues, namely global warming. This response aims to stimulate reflection on some of the implicit assumptions underpinning the relationships between science, technology and the public. I argue that an underestimation of the political and ethical dimensions of science and technology limits the possibilities for education to set the agenda for citizens’ participation in science and technological matters. Drawing on Sheila Jasanoff’s model of co-production, this paper proposes a radical re-affirmation of the aims and purposes of science education to embrace a multiplicity of disciplines, narratives and ways of knowing in science, technology and society issues.     

Students' argumentation in decision-making on a socio-scientific issue: implications for teaching

This study explores the arguments used by 14-year-old students in making decisions about the design of a road in their area. The whole activity was based on an actual problem at the time the research took place. The procedure was a sequence, where students worked first individually, then in groups and finally they had to take a class decision. Then they had to realize one of the final proposals and design the construction of a bridge that their planning had involved. This paper first elaborates the general perspective of such an approach; it then describes the process of argumentation and analyses the nature of the students' arguments, which are discussed on the basis of a specifically constructed network.     

A perspective on knowing about global warming and a critical comment about schools and curriculum in relation to socio-scientific issues

The focus of this response to Virginie Albe and Marie-José Gombert??s (2011) article on a research study of students?? school science conference on global warming is to develop some thoughts on covert assumptions which underpin any such conference. My comments refer to the politics behind the production of scientific knowledge of climate change and the institutional barriers to action on socio-scientific issues presented by schools working predominantly on neoliberal agendas.     

Learning science content through socio-scientific issues-based instruction: a multi-level assessment study

Science educators have presented numerous conceptual and theoretical arguments in favor of teaching science through the exploration of socio-scientific issues (SSI). However, the empirical knowledge base regarding the extent to which SSI-based instruction supports student learning of science content is limited both in terms of the number of studies that have been conducted in this area and the quality of research. This research sought to answer two questions: (1) To what extent does SSI-based instruction support student learning of science content? and (2) How do assessments at variable distances from the curriculum reveal patterns of learning associated with SSI-based instruction? Sixty-nine secondary students taught by three teachers participated in the study. Three teachers implemented an SSI intervention focused on the use of biotechnology for identifying and treating sexually transmitted diseases. We found that students demonstrated statistically and practically significant gains in content knowledge as measured by both proximal and distal assessments. These findings support the claim that SSI-based teaching can foster content learning and improved performance on high-stakes tests.     

Creating a dialogic environment for transformative science teaching practices: towards an inclusive education for science

Abstract

This paper focuses on the design and application of a teacher training strategy to promote the inclusive education of students with disabilities in the science classroom, through the creation of adult learning environments grounded on the principles of dialogic learning. Participants of the workshop proposal consisted of a group of twelve teachers who were working at various educational levels. Teacher teams proposed and implemented in their classroom, innovative, inclusive science-learning activities about a topic of their choice. Data were collected from interviews with teachers five months after the courses, teachers’ portfolios about their practice during implementation of such sequences, and researchers’ observations. The data suggest that it is possible to stimulate a gradual transformation of teaching practices through a teacher training proposal that promotes self-awareness and critical reflection, situated in the creation of meaning and a willingness to change in the spirit of solidarity and social action. We found elements to recommend the incorporation of these innovations at the curricular and practical level for teacher training schools and for in-service teacher development programmes in Mexico and elsewhere.     

Becoming a literacy teacher: approximations in critical literacy teaching

The new literacy studies (NLS) is a tradition of research that includes ethnographic work on literacy that has many applications for classroom teachers. The NLS include explorations of local literacies and critical literacy as well as the notion of literacy itself. When teachers draw on the NLS, students are able to draw on their practices in critical and transformative ways. However, NLS perspectives have not been used to examine how teachers are prepared in pre‐service programs and the ways critical literacy practices develop. This paper examines how two pre‐service teachers learn to take up definitions of local literacies in their work with students from racially, linguistically, and culturally diverse backgrounds in practicum settings. They use approximations in literacy teaching to design practices with students, demonstrating the process of becoming a teacher of literacy. I conclude with recommendations for teacher educators who are interested in supporting such approximations.     

Science education as a pathway to teaching language literacy: a critical book review

In this paper, I present a critical review of the recent book, Science Education as a Pathway to Teaching Language Literacy, edited by Alberto J. Rodriguez. This volume is a timely collection of essays in which the authors bring to attention both the successes and challenges of integrating science instruction with literacy instruction (and vice versa). Although several themes in the book merit further attention, a central unifying issue throughout all of the chapters is the task of designing instruction which (1) gives students access to the dominant Discourses in science and literacy, (2) builds on students’ lived experiences, and (3) connects new material to socially and culturally relevant contexts in both science and literacy instruction—all within the high stakes testing realities of teachers and students in public schools. In this review, I illustrate how the authors of these essays effectively address this formidable challenge through research that ‘ascends to the concrete’. I also discuss where we could build on the work of the authors to integrate literacy and science instruction with the purpose of ‘humanizing and democratizing’ science education in K-12 classrooms.     

State-mandated accountability as a constraint on teaching and learning science

The purpose of this study is to examine the effect of state-mandated policy, emphasizing control through performance-based instruction and student test scores as the basis for determining school accreditation, on the teaching and learning of science. The intended consequence of instigating the rational theory of management by one state is to improve their current level of student literacy. However, some contend that the implementation of the policy has results that are not intended. The identification of the tension between the intended and unintended results of centralized policy making is the basis for examining a specific case in which the rational model is implemented. One hundred and sixty-five seventh-grade science students and four teachers are participants in the study. Qualitative analysis is the research methodology used as a means to provide detailed information about the contextual nature of the classroom processes. The intention is to identify and describe features of the behavior setting that influence the behavior of the teachers and their students. Three assertions generated during the field work were: Teachers redefine the goals of science instruction as the acquisition of facts and isolated skills, teachers alter their usual instructional behavior to implement uniform instructional procedures, and the teacher/student classroom interaction constrains students' opportunities to learn science. The implications of the study indicate that the state-mandated policy has results that are in opposition to the intended results. Instead of improving the practices of teachers, the implementation of the policy constrains and routinizes the teachers' behavior, causing them to violate their own standards of good teaching. They feel pressured to “get through” the materials so students will score well on tests. The classroom interaction is structured in such a way as to inhibit students from asking questions of their own. As a result, students' opportunity to express curiosity and inquiry—central processes in scientific thinking—are constrained. These unintended consequences of the implemented state policy, instead of improving science teaching and learning, continue to reduce science instruction to the literal comprehension of isolated facts and skills.     

Consequences of political and educational measures on teaching first year university science

The study reported in this paper describes how higher order political and educational conditions unintentionally emphasize the teaching-learning practice in a specific subject (eg. a first year chemistry course at the Royal Veterinary and Agricultural University of Denmark). It is pointed out that the budgetary market economy model for financing higher education institutions that is currently used, the admission procedures and specific entrance requirements to that university, in addition to the chosen curriculum structure combine to single out the chemistry course as a gate-keeper governing the enrolment to that university. A high failure rate in this course was defined more as a teaching-learning problem rather than as a consequence of the higher order educational planning.     

Application of construal level and value-belief norm theories to undergraduate decision-making on a wildlife socio-scientific issue

One aim of science education is to develop scientific literacy for decision-making in daily life. Socio-scientific issues (SSI) and structured decision-making frameworks can help students reach these objectives. This research uses value belief norm (VBN) theory and construal level theory (CLT) to explore students’ use of personal values in their decision-making processes and the relationship between abstract and concrete problematization and their decision-making. Using mixed methods, we conclude that the level of abstraction with which students problematise a prairie dog agricultural production and ecosystem preservation issue has a significant relationship to the values students used in the decision-making process. However, neither abstraction of the problem statement nor students’ surveyed value orientations were significantly related to students’ final decisions. These results may help inform teachers’ understanding of students and their use of a structured-decision making tool in a classroom, and aid researchers in understanding if these tools help students remain objective in their analyses of complex SSIs.     

The attenuation of correlation coefficients: a statistical literacy issue

Much of the science reported in the media depends on correlation coefficients. But the size of correlation coefficients depends, in part, on the reliability with which the correlated variables are measured. Understanding this is a statistical literacy issue.     

Primary teachers conducting inquiry projects: effects on attitudes towards teaching science and conducting inquiry

ABSTRACT

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers’ attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers’ attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers’ attitudes, but that it may not be sufficient to fully change primary teachers’ attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers’ attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers’ attitudes and classroom practices.
