A considerable body of evidence highlights how inquiry-based science can enhance students' epistemic and conceptual understanding of scientific concepts, principles, and theories. However, little is known about how students view themselves as learners of science. In this paper, we explore primary children's images of doing science in school and how they compare themselves with ‘real’ scientists. Data were collected through the use of a questionnaire, drawing activity, and interviews from 161 Grade 4 (ages 9–10) students in Singapore. Results indicate that ‘doing science as conducting hands-on investigations’, ‘doing science as learning from the teacher’, ‘doing science as completing the workbook’, and ‘doing science as a social process’ are the images of learning science in school that most of the students held. In addition, students reported that they need to be well behaved first and foremost, while scientists are more likely to work alone and do things that are dangerous. Moreover, students often viewed themselves as ‘acting like a scientist’ in class, especially when they were doing experiments. Nevertheless, some students reported that they were unlike a scientist because they believed that scientists work alone with dangerous experiments and do not need to listen to the teacher and complete the workbook. These research findings further confirm the earlier argument that young children can make distinctions between school science and ‘real’ science. This study suggests that the teaching of science as inquiry and by inquiry will shape how students view their classroom experiences and their attitudes towards science.  相似文献

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.  相似文献

Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students’ learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students’ inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists’ practices is very much needed. Within this context there is a need to re-examine the science teachers’ views of scientists and the cultural factors that might have an impact on teachers’ views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative–qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers’ cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists.  相似文献

Previous research has highlighted challenges associated with embracing an inquiry approach to science teaching for primary teachers, often associating these challenges with insecurity linked to the lack of content knowledge. We argue that in order to understand the extent to which primary student teachers are able to embrace science teaching informed by scientific literacy for all, it is important to take into account various, sometimes competing, science teacher and primary teacher Discourses. The aim of this paper is to explore how such Discourses are constituted in the context of learning to teach during a 1-year university-based Post Graduate Certificate of Education course. The empirical data consist of semi-structured interviews with 11 student teachers. The analysis identifies 5 teacher Discourses and we argue that these can help us to better understand some of the tensions involved in becoming a primary teacher with a responsibility for teaching science: for example, in terms of the interplay between the student teachers' own educational biographies and institutionally sanctioned Discourses. One conclusion is that student teachers' willingness and ability to embrace a Discourse of science education, informed by the aim of scientific literacy for all, may be every bit as constrained by their experience of learning science through ‘traditional schooling’ as it is by their confidence with respect to their own subject knowledge. The 5 Discourses, with their complex interrelations, raise questions about which identity positions are available to students in the intersections of the Discourses and which identity positions teacher educators may seek to make available for their students.  相似文献

In order to promote scientific inquiry in secondary schooling in Taiwan, the study developed a computer-based inquiry curriculum (including structured and guided inquiry units) and investigated how the curriculum influenced students’ science learning. The curriculum was implemented in 5 junior secondary schools in the context of a weeklong summer science course with 117 students. We first used a multi-level assessment approach to evaluate the students’ learning outcomes with the curriculum. Then, a path analysis approach was adopted for investigating at different assessment levels how the curriculum as a whole and how different types of inquiry units affected the students’ development of conceptual understandings and inquiry abilities. The results showed that the curriculum was effective in enhancing the students’ conceptual knowledge and inquiry abilities in the contexts of the six scientific topics. After the curriculum, they were able to construct interconnected scientific knowledge. The path diagrams suggested that, due to different instructional designs, the structured and guided inquiry units appeared to support the students’ learning of the topics in different ways. More importantly, they demonstrated graphically how the learning of content knowledge and inquiry ability mutually influenced one another and were reciprocally developed in a computer-based inquiry learning environment.  相似文献

The purposes of this study were, based on John Dewey’s ideas on experience, to examine how primary students used their own everyday experience and were affected by own and others’ experience in science discourse, and to illuminate the implications of experience in science education. To do these, science discourses by a group of six fourth-graders were observed, where they talked about their ideas related to thermal concepts. The data was collected through interviews and open-ended questions, analyzed based on Dewey’s perspective, and depicted as the discourse map which was developed to illustrate students’ transaction and changing process of students’ ideas. The results of the analysis showed typical examples of Dewey’s notions of experience, such as the principles of continuity and of transaction and of different types of experience, examples of ‘the expanded continuity and transaction’, and science discourse as inquiry. It was also found that students’ everyday experiences played several roles: as a rebuttal for changing their own ideas or others’, backing for assurance of their own ideas in individual students’ inner changes after discourse with others, and backing for other’s ideas. Based on these observations, this study argues that everyday experience should be considered as a starting point for primary students’ science learning because most of their experience comes from everyday, not school science, contexts. In addition, to evoke educative experience in science education, it is important for teachers to pay more attention to Dewey’s notions of the principles of continuity and of transaction and to their educational implications.  相似文献

In this paper, we will explore how Albert Camus has much to offer philosophers of education. Although a number of educationalists have attempted to explicate the educational implications of Camus’ literary works, these analyses have not attempted to extrapolate pedagogical guidelines towards developing an educational framework for children’s philosophical practice in the way Matthew Lipman did from John Dewey’s philosophy of education, which informed his philosophy for children curriculum and pedagogy. We focus on the phenomenology of inquiry; that is, inquiry that begins with genuinely felt doubt, pointing to a problematic to which the inquirer seeks a solution or resolution. We argue that the central purpose of education is to develop lucid individuals. To this end, we concentrate on Dewey and the pragmatist tradition, starting from Peirce, leading to Lipman’s development of Dewey’s educational guidelines into classroom practice. We show where Camus and the pragmatists are congruent in their thinking, insofar as they can inform the educative process of the community of inquiry. What we conclude is that the role of the teacher is to develop lucid individuals facilitated in a classroom that is transformed into a community of inquiry embedded in contemporary historical moments.  相似文献

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed.  相似文献

Inquiry engagement is a newly defined construct that represents the participation in carrying out practices of science and engineering to achieve learning outcomes and is influenced by learners’ personalities and teachers’ roles. Expectancy value theory posits that attainment values are important components of task values that, in turn, directly influence students’ achievement-related choices and performance. The current paper developed and validated the McGill Attainment Value for Inquiry Engagement Survey (MAVIES) with undergraduate students in STEM disciplines. The MAVIES is a 67-item, learner-focused survey that addresses four components that are theoretically important for engaging in scientific inquiry: (a) teachers’ roles, (b) students’ personalities, (c) inquiry learning outcomes, and (d) practices of science and engineering. Evidence for internal consistency and construct, content, and criterion validity was obtained from 85 undergraduates who had experience with scientific inquiry in diverse STEM fields. Confirmatory factor analyses confirmed factors that were consistent with role theory, Big Five personality traits, revised Bloom’s learning outcomes, and the Next Generation Science Standards. The MAVIES instrument is a reliable and valid instrument for measuring undergraduate students’ attainment values for scientific inquiry engagement in STEM disciplines.  相似文献

Studies show that teachers and students use humour when communicating with each other in a science education context. This study investigates the use of humour during a collaborative inquiry laboratory task on an undergraduate chemistry course and an undergraduate physics course. Seven groups of students working on a collaborative inquiry task were recorded on video. The videos were analysed utilising an analytical framework based on conversation analysis. During the tasks, humour was used in a dynamic way and the role of humour changed as the inquiry progressed. As expected, humour was used to create a group identity and to regulate negative emotions such as anxiety, frustration, uncertainty, boredom and disappointment. Humour also had an integral role in collaborative decision-making, for example in proposing and evaluating new ideas. Awareness of how humour can contribute to the regulation of emotions and collaborative decision-making might help students and teachers to better utilise humour in inquiry and learning.  相似文献

Modeling, like inquiry more generally, is not a single method, but rather a complex suite of strategies. Philosophers of biology, citing the diverse aims, interests, and disciplinary cultures of biologists, argue that modeling is best understood in the context of its epistemic aims and cognitive payoffs. In the science education literature, modeling has been discussed in a variety of ways, but often without explicit reference to the diversity of roles models play in scientific practice. We aim to expand and bring clarity to the myriad uses of models in science by presenting a framework from philosopher of biology Jay Odenbaugh that describes five pragmatic strategies of model use in the biological sciences. We then present illustrative examples of each of these roles from an empirical study of an undergraduate biological modeling curriculum, which highlight how students used models to help them frame their research question, explore ideas, and refine their conceptual understanding in an educational setting. Our aim is to begin to explicate the definition of modeling in science in a way that will allow educators and curriculum developers to make informed choices about how and for what purpose modeling enters science classrooms.  相似文献

This article discusses how to deal with the relations between different cultural perspectives in classrooms, based on a proposal for considering understanding and knowledge as goals of science education, inspired by Dewey’s naturalistic humanism. It thus combines educational and philosophical interests. In educational terms, our concerns relate to how science teachers position themselves in multicultural classrooms. In philosophical terms, we are interested in discussing the relations between belief, understanding, and knowledge under the light of Dewey’s philosophy. We present a synthesis of Dewey’s theory of inquiry through his naturalistic humanism and discuss its implications for the concepts of belief, understanding, and knowledge, as well as for the goals of science teaching. In particular, we highlight problems arising in the context of possible conflicts between scientific and religious claims in the school environment that result from totalitarian positions. We characterize an individual’s position as totalitarian if he or she takes some way of thinking as the only one capable of expressing the truth about all that exists in the world, lacks open-mindedness to understand different interpretative perspectives, and attempts to impose her or his interpretation about the facts to others by violent means or not. From this stance, any other perspective is taken to be false a priori and, accordingly, as a putative target to be suppressed or adapted to the privileged way of thinking. We argue, instead, for a more fallibilist evaluation of our own beliefs and a more respectful appraisal of the diversity of students’ beliefs by both students and teachers.  相似文献

The Next Generation Science Standards support understanding of the nature of science as it is practiced and experienced in the real world through interconnected concepts to be imbedded within scientific practices and crosscutting concepts. This study explored how fourth and fifth grade elementary students’ views of nature of science change when they engage in a technology-enhanced, scientific inquiry-oriented curriculum that takes place across formal and informal settings. Results suggest that student engagement in technology-enhanced inquiry activities that occur in informal and formal settings when supported through explicit instruction focused on metacognitive and social knowledge construction can improve elementary students’ understanding of nature of science.

Research on predictors of achievement in science is often targeted on more traditional content-based assessments and single student characteristics. At the same time, the development of skills in the field of scientific inquiry constitutes a focal point of interest for science education. Against this background, the purpose of this study was to investigate to which extent multiple student characteristics contribute to skills of scientific inquiry. Based on a theoretical framework describing nine epistemological acts, we constructed and administered a multiple-choice test that assesses these skills in lower and upper secondary school level (n?=?780). The test items contained problem-solving situations that occur during chemical investigations in school and had to be solved by choosing an appropriate inquiry procedure. We collected further data on 12 cognitive, motivational, and sociodemographic variables such as conceptual knowledge, enjoyment of chemistry, or language spoken at home. Plausible values were drawn to quantify students’ inquiry skills. The results show that students’ characteristics predict their inquiry skills to a large extent (55%), whereas 9 out of 12 variables contribute significantly on a multivariate level. The influence of sociodemographic traits such as gender or the social background becomes non-significant after controlling for cognitive and motivational variables. Furthermore, the performance advance of students from upper secondary school level can be explained by controlling for cognitive covariates. We discuss our findings with regard to curricular aspects and raise the question whether the inquiry skills can be considered as an autonomous trait in science education research.  相似文献

Helping students to use and interpret representations in science is critically important if they are to become scientifically literate and able to engage in the discourses related to understanding scientific issues. The purpose of this case-study is to report on how one Year 5 teacher in a small, city school in Brisbane, Australia used different visual, embodied, and language representations to capture students’ engagement in the inquiry tasks. While the case study showed that the students demonstrated clear understandings of the relationships between the different scientific phenomena they were investigating, there is no evidence that these ways of thinking and talking generalised to other inquiry-science topics.However, the case study does provide insights into how this teacher used different visual, embodied, and language strategies to help the students in his class develop complex understandings of the inquiry-science unit they were studying.  相似文献

Practical reasoning is a fundamental competence required for everyday decision-making as well as for the production of scientific knowledge. However, very little attention is given to developing this competence in school science classrooms or in educational research programs. In this paper we explain the tradition of practical reasoning and its relevance to science and science education. We then suggest ways in which practical reasoning may be developed in students such that they are enabled to better understand how scientific knowledge is produced and how they may be better able to contribute to improving scientific practices.  相似文献
