Over the last 20 years, science education studies have reported that there are very different understandings among students of science regarding the key aspects of climate change. We used the cognitive linguistic framework of experientialism to shed new light on this valuable pool of studies to identify the conceptual resources of understanding climate change. In our study, we interviewed 35 secondary school students on their understanding of the greenhouse effect and analysed the conceptions of climate scientists as drawn from textbooks and research reports. We analysed all data by metaphor analysis and qualitative content analysis to gain insight into students' and scientists' resources for understanding. In our analysis, we found that students and scientists refer to the same schemata to understand the greenhouse effect. We categorised their conceptions into three different principles the conceptions are based on: warming by more input, warming by less output, and warming by a new equilibrium. By interrelating students' and scientists' conceptions, we identified the students' learning demand: First, our students were afforded with experiences regarding the interactions of electromagnetic radiation and CO2. Second, our students reflected about the experience-based schemata they use as source domains for metaphorical understanding of the greenhouse effect. By uncovering the—mostly unconscious—deployed schemata, we gave students access to their source domains. We implemented these teaching guidelines in interventions and evaluated them in teaching experiments to develop evidence-based and theory-guided learning activities on the greenhouse effect.  相似文献

Although many environmental and science educators have explored students’ conceptual understandings, misconceptions, and knowledge of the greenhouse effect, global warming, and climate change, few have investigated the ways students conceptualize climate as a system or how components of the system influence climate. Therefore, the purpose of this study was to begin the process of understanding how US students conceptualize a climate system. A total of 42 seventh grade students (ages 12–13) from the Midwest completed an open-response task. From the inductive analysis of student written responses, 22 codes emerged that reflected students’ conceptions of the climate system. From these codes, three path diagrams were constructed that illustrate these students’ conceptions about how a climate system influences climate and how greenhouse gases and global warming impact the climate system. A generalized model of students’ conception of a climate system was generated. Students in this study conceptualized a climate system in a unidirectional, linear, cause and effect relationship that emphasized the atmospheric component of the climate system.  相似文献

Climate change is one of the most significant science issues facing humanity; yet, teaching students about climate change is challenging: not only is it multidisciplinary, but also it is contentious and debated in political, social and media forums. Students need to be equipped with an understanding of climate change science to be able to participate in this discourse. The purpose of this study was to examine Western Australian high school students’ understanding of climate change and the greenhouse effect, in order to identify their alternative conceptions about climate change science and provide a baseline for more effective teaching. A questionnaire designed to elicit students’ understanding and alternative conceptions was completed by 438 Year 10 students (14–15 years old). A further 20 students were interviewed. Results showed that students know different features of both climate change and the greenhouse effect, however not necessarily all of them and the relationships between. Five categories of alternative conceptions were identified. The categories were (1) the greenhouse effect and the ozone layer; (2) types of greenhouse gases; (3) types of radiation; (4) weather and climate and (5) air pollution. These findings provide science educators a basis upon which to develop strategies and curriculum resources to improve their students’ understanding and decision-making skills about the socioscientific issue, climate change.  相似文献

An analysis of students’ conceptions on climate change shows a great confusion on key aspects of global warming. Even after instruction students often hold conceptions that differ from scientists’ conceptions. Student’s conceptions on global warming were collected in a reanalysis of 24 studies on everyday concepts of global warming as well as in an own interview study with 35 18-year-old students from German grammar schools. Climate-scientists conceptions were analysed from textbooks and research reports in a literature study. All data were analysed by systematic metaphor analysis and qualitative content analysis. Experientialism as a theory of metaphor provided insight in the process of understanding. The analysis of conceptions by experientialism shows that students and scientists have different metaphorical conceptions of global warming – but both refer to the same schemata. These schemata in mind we categorised the conceptions of global warming. Hereby we identified different thinking patterns in students’ and scientists’ conceptions. Following the model of educational reconstruction we took the metaphorical conceptions as a starting point for the development of learning environments. By uncovering the – mostly unconsciously – employed schemata, we gave students access to their metaphorical conceptions and let them reflect on their mental models.  相似文献

The central goal of this study was to create a new diagnostic tool to identify organic chemistry students’ alternative conceptions related to acid strength. Twenty years of research on secondary and college students’ conceptions about acids and bases has shown that these important concepts are difficult for students to apply to qualitative problem solving. Yet, few published studies document how students’ prior knowledge of acids influences their understanding of acid strength in organic chemistry contexts. We developed a nine-item multiple-tier, multiple-choice concept inventory to identify alternative conceptions that organic chemistry students hold about acid strength, to determine the prevalence of these conceptions, and to determine how strongly these conceptions bias student reasoning. We identified two significant alternative conceptions that organic chemistry students hold about acid strength. Students who answered items incorrectly were more confident about their answers than peers who answered items correctly, suggesting that after one semester of organic chemistry, students do not know what they do not know. Implications for the teaching of acid strength are discussed.  相似文献

The United Nations’ declaration on climate change education in December 2014 has sparked a renewal of policies and programs initiated during the ‘Decade of Education for Sustainable Development’ (DESD, 2005–2014), aimed at promoting awareness, understanding, and civic action for environmental sustainability within learning communities all around the world. We present findings from a dialogic, multimodal, and literacies-based educational project designed to provide secondary students (N?=?141) from four countries with the resources to read about and discuss evidence regarding climate change from seminal studies with peers and a core group of scientists (N?=?7). Post-program interviews revealed a significant increase in language use related to evidence-based reasoning. Students also demonstrated an increased propensity to recycle. These findings support the hypothesis that providing opportunities for students to read and discuss seminal scientific sources incites positive changes in beliefs, attitudes, and behaviors related to climate change and climate science, and understandings of the nature of scientific evidence and argumentation.  相似文献

The tensions between environmental protection and economic growth are critical to future well-being, and it is therefore important to understand how young people conceptualize these tensions. The aim of the present study is to explore students’ solutions to the dilemma of economic development and mitigating climate change, with regard to societal responses to the challenge of climate change. The study was conducted in China’s Green Schools. Green School is an international long-term programme with the aim of increasing students’ knowledge of environmental issues, and transferring this knowledge into positive actions to affect the wider community. The data were obtained through semi-structured pre- and post-interviews with 15–16-year-old students in three groups (12 students) from Green Schools in the Beijing area. The results show that students’ discussions focused exclusively on economic growth and social welfare. Students seem to believe that environmental problems are inevitable, nature is a ‘box’ of resources, and economic development is necessary in order to sustain and even improve nature. Therefore, there is no dilemma between economic development and environmental protection. The paper ends with a discussion on research and implications for teaching climate change.  相似文献

As biotechnology‐related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students’ ideas about this issue. Very few studies have investigated learners’ ideas about biotechnology. Our study was designed to understand the types of alternative conceptions students hold concerning SCR. The qualitative research design allowed us to examine college students’ understandings about stem cells and SCR. More specifically, we addressed the following questions: How can alternative conceptions about stem cell topics be categorized? What types of alternative conceptions are most common? Participants included 132 students enrolled in a biotechnology course that focused on the scientific background of biotechnology applications relevant to citizens. In this study, we used an inductive approach to develop a taxonomy of alternative ideas about SCR by analyzing student responses to multiple open‐ended data sources. We identified five categories of conceptions: alternative conceptions about what, alternative conceptions about how, alternative conceptions about medical potential, terminology confusion, and political and legal alternative conceptions. In order to improve instruction, it is important to understand students’ ideas when entering the classroom. Our findings highlight a need to teach how science can be applied to societal issues and improve science literacy and citizenship.  相似文献

Misconceptions about climate change science are pervasive among the US public. This study investigated the possibility that these misconceptions may be reflective of science teachers’ knowledge and teaching of climate change science. Florida and Puerto Rico secondary science teachers who claim to teach extensively about climate change were surveyed in regard to their conceptions of climate change science and the climate change-related topics they teach. Results show that many teachers hold naïve views about climate change (e.g. that ozone layer depletion is a primary cause of climate change) and climate change science (e.g. that it must be based on controlled experiments for it to be valid). In addition, teachers in both groups neglect crucial topics such as how evidence for climate change is developed and the social, political, and economic dimensions of climate change. Our results suggest the need for teachers to understand how to teach climate change and the nature of climate change science using authentic contexts that promote effective socioscientific decision-making and climate change mitigation.  相似文献

Many authors have claimed that participatory perspectives should be a significant feature of environmental and sustainability education (ESE). This change in ESE practice implies a relocation of the process of environmental knowledge constitution from ‘before’ to ‘in’ the educational event. The aim of this paper is to clarify both the processes of knowledge constitution and the content of the constituted knowledge within participatory ESE practices. Two methods based on John Dewey’s transactional perspective are used in the study: epistemological move analysis and pragmatic discourse analysis. The empirical material consists of video-recorded student discussions about climate change in the setting of a Swedish upper secondary school with a pronounced sustainability approach. In the analyses, six different epistemological moves used by the students are identified. The analyses show how students cooperatively constitute a specific view of climate change by using these moves. A main conclusion of this study is that participatory approaches do not necessarily mean that knowledge becomes more diverse. It is therefore important that teachers pay attention to governing processes among students and occasionally challenge the common view in order to allow for alternative possibilities and views.  相似文献

ABSTRACT

Climate change is one of the significant global challenges currently facing humanity. Even though its seriousness seems to be common knowledge among the public, the reaction of individuals to it has been slow and uncertain. Many studies assert that simply knowing about climate change is not enough to generate people’s behavioural response. They claim, indeed, that in some cases scientific literacy can even obstruct behavioural response instead. However, recent surveys show a rather poor understanding of climate dynamics and argue that lack of knowledge about causal relationships within climate dynamics can hinder behavioural response, since the individual is not able to understand his/her role as causal agent and therefore doesn’t know how to take proper action. This study starts from the hypothesis that scientific knowledge focused on clarifying climate dynamics can make people understand not only dynamics themselves, but also their interactive relationship with the environment. Teaching materials on climate change based on such considerations were designed and implemented in a course for secondary-school students with the aim of investigating whether this kind of knowledge had an influence on students’ willingness to adopt pro-environmental behaviours. Questionnaires were delivered for testing the effect of the teaching experience on knowledge and behaviour.  相似文献

Individual behaviour change is fast becoming a kind of ‘holy grail’ to tackle climate change, in environmental policy, the environmental movement and academic literature. This is contested by those who claim that social structures are the main problem and who advocate collective social action. The objective of the research presented in this paper is to better understand why environmentally concerned citizens choose one of these two types of engagement. Our focus is on the role of experiences of and/or convictions about power in shaping this choice. Within the framework of an explorative qualitative study, we engaged in in-depth interviews with 12 young environmentally concerned citizens. On this basis, five main findings are elaborated. Firstly, powerlessness is shown to be a crucial experience, whatever the respondents’ engagement. Secondly, ‘strategy scepticism’ seems to be a more important obstacle for engagement than ‘climate scepticism’. Thirdly, many respondents express significant resistance towards being ‘conditioned’ by awareness-raising campaigns. Fourthly, a ‘gap’ is observed between respondents’ analysis and their strategy proposals. Finally, we underscore another important gap between concrete and abstract levels in respondents’ discourses. All these findings disclose paradoxical aspects of the role of power in shaping the concerned citizens’ engaged choices.  相似文献

A crucial skill for researchers in inter- and transdisciplinary environmental projects is the ability to be reflexive about knowledge and knowledge production. Few studies exist on the operationalization of reflexive skills and teaching and learning strategies that help students master these skills. This research aims to contribute in this direction. We distinguished two components of reflexive skills: (i) assessing the relative contributions of scientific disciplines and non-academic knowledge in addressing environmental issues; (ii) assessing the role of norms and values in research. We developed a framework for teaching and learning reflexive skills and evaluated this framework within a quasi-experimental educational setting involving 3 groups of 30 students. Students’ reflexive skills were assessed quantitatively using a pre- and post-test questionnaire. Moreover, students’ reflection papers were analysed to get a better understanding of their perspectives on the teaching and learning framework. We show that it is possible to train students in reflexive skills, but it requires a well-designed learning setting.  相似文献

Abstract

Although research suggests that family dynamics likely play a role in shaping children’s behaviors, few studies focus on environmental behaviors, and none to our knowledge investigate how parents shape climate change mitigation behaviors among their children. We begin to fill this gap through a quantitative case study using matched household-level survey data from 182 coastal North Carolina families (n?=?241 parents aged 29–77; n?=?182 students aged 11–14) associated with 15 middle school science teachers. Family climate change discussions, parent behaviors, and children’s climate change concern levels predicted the degree to which children will participate in individual-level climate mitigation behaviors. These results provide evidence that promoting climate-related conversations within households may promote climate action even when parents are apathetic about climate change. Similarly, parental behaviors, but not their concern levels, were important predictors of adolescent behaviors. This study highlights novel ways that family dynamics may promote climate change mitigating behaviors and a new pathway to promoting climate mitigation at familial, and ultimately, societal levels.  相似文献

Abstract

There is extensive evidence showing that the climate system is warming and human behavior is linked to the change. Despite increasing attempts to integrate climate change into school curricula, teachers have challenges in preparing and implementing climate change lessons. The study aims to look at (a) the kinds of wondering questions middle school students construct after they are engaged in a climate change activity called ‘It’s a Gassy World’ and (b) what teachers highlight in their reflections on these questions to improve their teaching. In this multi-case explorative study, the data comes from student artifacts, teachers’ written reflections, and semi-structured conversational interviews with teachers. A constant-comparative analysis of students’ wondering questions (N = 165) showed that the nature of the questions varies. These were grouped under three different categories: direct observation, interdisciplinary connections, and future projections questions. We then analyzed five teachers’ written reflections and interviews from a cultural historical activity theoretical perspective. This analysis revealed that teachers paid particular attention to certain tools (physical and conceptual), norms (epistemic and teaching), emotions, and division of labor routines in classrooms. We discuss how students’ wondering questions help teachers notice essential features of climate change learning such as spatiotemporal thinking.  相似文献

In this paper, a framework for developing first‐year students' learning is proposed. Its aim is to increase university managers' and teachers' awareness of two issues: (1) that the currently predominant ‘skills’ approaches to the enhancement of student learning are based on a deficiency model and achieve little more than remedying the overt problems of individual students and (2) that a holistic, subject‐specific approach is needed to support all students in the complex process of learning to learn in higher education. The framework aims at facilitating transition to university by helping students to understand what is expected from them at university, by addressing their conceptions of learning and knowledge and by gradually developing their competence as independent learners as well as their competence in constructing knowledge in their discipline. Different contexts are used to apply complementary methods for the development of learning. As the framework relies on the engagement of academic teachers, it is critical that university managers and policy makers give appropriate recognition to effective teaching. This involves instigating changes in conceptions of teaching, providing opportunities for educational development and setting incentives for teachers' commitment to student learning.  相似文献

Abstract

This article explores changes of environmental values and beliefs among secondary school business and economics students regarding government and market solutions to climate change. The quantitative study is longitudinal and a survey was administrated to students at two occasions including 212 participants in the first measurement. Results show a small significant increase in importance for altruistic, biospheric and egoistic value orientations at average. At an individual level, there are substantial movements over time. Nearly two-thirds of the students changed the strength of their value orientations over time. Taxes and legislation were regarded as the most effective solutions to climate change, however there was a decrease in seeing market prices as important mechanisms for change. Analysis suggested no direct relationship between change in environmental value orientation and change in norms. However indirect associations were mediated by changing beliefs in the efficacy of education and information and the efficacy of tax policies. For example, students who became more egoistic and more convinced about the efficacy of tax were less likely than others to be willing to take personal actions.  相似文献

ABSTRACT

Graduate students regularly teach undergraduate STEM courses and can positively impact students’ understanding of science. Yet little research examines graduate students’ knowledge about nature of science (NOS) or instructional strategies for teaching graduate students about NOS. This exploratory study sought to understand how a 1-credit Teaching in Higher Education course that utilised an explicit, reflective, and mixed-context approach to NOS instruction impacted STEM graduate students’ NOS conceptions and teaching intentions. Participants included 13 graduate students. Data sources included the Views of Nature of Science (VNOS-Form C) questionnaire administered pre- and post-instruction, semi-structured interviews with a subset of participants, and a NOS-related course project. Prior to instruction participants held many alternative NOS conceptions. Post-instruction, participants’ NOS conceptions improved substantially, particularly in their understandings of theories and laws and the tentative nature of scientific knowledge. All 12 participants planning to teach NOS intended to use explicit instructional approaches. A majority of participants also integrated novel ideas to their intended NOS instruction. These results suggest that a teaching methods course for graduate students with embedded NOS instruction can address alternative NOS conceptions and facilitate intended use of effective NOS instruction. Future research understanding graduate students' NOS understandings and actual NOS instruction is warranted.  相似文献

Empirical investigations on students’ conceptions of cell biology indicate major misunderstandings of scientific concepts even after thorough teaching. Therefore, the main aim of our research project was to investigate students’ difficulties in learning this topic and to study the impact of learning activities on students’ conceptions. Using the Model of Educational Reconstruction, a four‐phase design was carried out. Firstly, there was the clarification of science subject matter. Secondly, students’ conceptions were investigated, and finally, the learning activities were designed. An evaluation of these learning activities was carried out using five teaching experiments, each with three 9th grade students (15–16 years, Grammar school). Interpretation of students’ “pathways of thinking” and their conceptual change during instruction was framed theoretically by experiential realism. Theoretical framework, methods and outcomes of the study may contribute to a deeper understanding of students’ ways of thinking in the field of cell biology and reveal the process of conceptual development by using well planned learning activities.  相似文献
