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

The historical under-representation of diverse youth in environmental science education is inextricably connected to access and identity-related issues. Many diverse youth with limited previous experience to the outdoors as a source for learning and/or leisure may consider environmental science as ‘unthinkable’. This is an ethnographic study of 16 diverse high school youths’ participation, none of who initially fashioned themselves as ‘outdoorsy’ or ‘animal people’, in a four-week summer enrichment program focused on herpetology (study of reptiles and amphibians). To function as ‘good’ participants, youth acted in ways that placed them well outside their comfort zones, which we labeled as identity boundary work. Results highlight the following cultural tools, norms, and practices that enabled youths’ identity boundary work: (1) boundary objects (tools regularly used in the program that facilitated youths’ engagement with animals and nature and helped them work through fear or discomfort); (2) time and space (responsive, to enable adaptation to new environments, organisms, and scientific field techniques); (3) social support and collective agency; and (4) scientific and anecdotal knowledge and skills. Findings suggest challenges to commonly held beliefs about equitable pedagogy, which assumes that scientific practices must be thinkable and/or relevant before youth engage meaningfully. Further, findings illustrate the ways that fear, in small doses and handled with empathy, may become a resource for youths’ connections to animals, nature, and science. Finally, we propose that youths’ situated identity boundary work in the program may have the potential to spark more sustained identity work, given additional experiences and support. 相似文献

A key educational objective for the twenty-first century is developing students’ epistemic agency. Epistemic agency is the active process of choosing when, what, where one learns and how one knows, as well as the capacity to create knowledge in a community. The knowledge-building communities model developed by Scardamalia and Bereiter was used in a New Zealand Year 13 distance art history class to support the development of students’ epistemic agency in 2013. In this study, students were given more control in the learning process, and were able to exercise epistemic agency through identifying their knowledge gaps, sharing information and ideas, developing ideas and creating communal knowledge. A number of factors that increased students’ development of epistemic agency are also discussed in this article. 相似文献

There is an urgent need to strengthen undergraduate science students’ epistemic knowledge, which requires having the scientists qua teachers on board. The divide between scientists’ perceptions of science and the perceptions held by those who study science is in this context problematic. Even so, this remains a sorely understudied area. The aim of the study was to identify pragmatic ways that hold the potential to facilitate integration of scholarly studies of scientific knowledge production with experientially based knowledge held by scientists to support the teaching of epistemic knowledge content to undergraduate science students. Earlier studies suggest that trust building is a central component. Our exploratory case study focuses on instructor perceptions and is based on informal interviews, participatory observation and surveys with instructors in a first-year undergraduate science course under revision. We identified the following central components as central to successful navigation of the divide between the scientific practice and science studies: Explicit formulation of learning objectives tied to epistemic knowledge acquisition; Conscious attention to vocabulary that triggers scientists’ aversion to science studies; Careful selection of historic and contemporary cases; and Systematic scaffolding of course activities. The conclusion regarding a common vocabulary stands out: by ridding our instructions from the vocabulary that caused concern among science instructors we succeeded in engaging them in conversations with students about the knowledge-producing process and challenge the view of science as characterised by facts and truths, rather than a form of scholarly inquiry that aims to produce knowledge about the natural world. 相似文献

This article discusses a narrative inquiry as a methodology for understanding and examining teachers' interpretations of their environment‐related teaching experiences. Focusing on the value of teacher stories for interrogating the discursive practices of schools as institutional contexts, four main rhetorical themes are identified to illustrate how teachers' engagements in practice and thinking with environmental education display ongoing identity work. Five Korean secondary science teachers' stories illustrate the dynamic processes and interplay between multiple discourses, such as the ‘proper’, ‘good’, ‘science’ teacher, and the cultural norms, resources and subject positions available to them, as they take up and explain their own and others' meanings and subject positions in science education and environmental education. The paper discusses the value of narrative inquiry to conceptualising teacher agency in ways that offer alternatives to conventional research perspectives in this field, and in taking account of the possible meanings of environmental education, the possibility of creating cracks and ruptures in the ‘sense‐making’ discourses and ‘sense that is made’ of experiences of environmental education and school education more widely. 相似文献

This study investigates the effects of an intensive 1-week Inquiry-Based Science and Technology Enrichment Program (InSTEP) designed for middle school-aged female students. InSTEP uses a guided/open inquiry approach that is deepened and redefined as eight sciences and engineering practices in the Next Generation Science Standards, which aimed at increasing female students’ interest in science and science-related careers. This study examined the effectiveness of InSTEP on 123 female students’ pre-assessment and post-assessment changes in attitudes toward science and content knowledge of selected science concepts. An attitude survey, a science content test with multiple-choice questions, written assignments, and interviews to collect data were all used to measure students’ attitudes and content knowledge. A within-group, repeated measure design was conducted, and the results indicated that at the post-intervention level, InSTEP increased the participants’ positive attitudes toward science, science-related careers, and content knowledge of selected science concepts. 相似文献

Science education reforms worldwide call on teachers to engage students in investigative approaches to instruction, like inquiry. Studies of teacher self-reported enactment indicate that inquiry is used frequently in the classroom, suggesting a high level of proficiency with inquiry that would be amenable to inquiry reform. However, it is unclear whether the high frequency of self-report is based on sound knowledge inquiry. In the absence of sound knowledge, high rates of self-reported enactment would be suspect. We conducted a study to measure teachers’ knowledge of inquiry as it related to the known, high frequency of reported enactment. We developed a multidimensional survey instrument using US reform documents and administered it to 149 K–12 teachers at a national science teachers’ conference. The majority of the teachers surveyed did not report inquiry enactment based on well-structured knowledge of inquiry. Interviews with participants showed how teachers could readily map non-inquiry activities onto inquiry statements taken directly from reform documents. From these results we argue that teachers often believed they were enacting inquiry, when likely they were not. We further reason that teachers may struggle to interpret and enact inquiry-related requirements of science education reform and will need support distinguishing inquiry from non-inquiry practices. 相似文献

ABSTRACTIn uncertain times for higher education learning communities, the risks of societal and epistemic dependence on a single globally dominant set of academic knowledge practices are evident. Nonetheless, many higher education institutions in developing nations struggle to achieve international presence unless they uncritically adopt these dominant practices, even where they recognise the need to use and promote local knowledge systems. We explore these dynamics in postcolonial Papua New Guinea, through an assessment of the intentions for internationalisation of the six PNG universities and barriers to agency. Our approach recognises the dialectical relationship between ‘internationalisation’ and ‘indigenisation’. We suggest that a pervasive but narrow view of indigenisation, emphasising the localisation of university staff, has hampered other forms of both indigenisation and internationalisation, producing more stasis than synthesis within PNG’s universities. Effective international agency by PNG universities, and their partners, requires more critical and continuous discourse between the international and the indigenous. 相似文献

The purpose of the study was to investigate how young students engage in an inquiry-based project driven by real-life contexts. Elementary school children were engaged in a small inquiry project centred on marine biodiversity and species adaptations. All activities included the exploration of an out-of-school setting as a learning context. A total of 49 students and 2 teachers were involved in the activities. The research methods included observation, document analysis and content analysis of the answers to a questionnaire and an interview. The results revealed that most of the students acquired scientific knowledge related to biological diversity and adaptations to habitat. Moreover, students progressively demonstrate greater autonomy, argumentative ability and decision-making. One implication of the present study is that elementary science curriculum could be better managed with inquiry project-based activities that explore different types of resources and out-of-school settings. 相似文献

This study investigated the effects of metaconceptually-enhanced, simulation-based inquiry learning on eighth grade students’ conceptual change in science and their development of science epistemic beliefs. Two experimental groups studied the topics of motion and force using the same computer simulations but with different simulation guides: one enhanced with metaconceptual scaffolding, while the other was not. The findings led to the following conclusions: (a) metaconceptual scaffolding enhanced simulation-based learning by significantly reducing science misconceptions, but it was not as effective in changing students’ mental models which consisted of multiple interrelated key concepts; (b) students’ beliefs about the speed of learning and the construction of knowledge were strong predictors of conceptual change learning outcomes; (c) epistemologically more mature students did not benefit more from metaconceptual interventions than those with less mature beliefs; (d) further interventions are needed to promote the development of students’ science epistemic beliefs in inquiry learning. 相似文献

Engaging in argumentation from evidence is challenging for most middle school students. We report the design of a media-based mentoring system to support middle school students in engaging in argumentation in the context of a game-infused science curriculum. Our design emphasizes learners apprenticing with college student mentors around the socio-scientific inquiry of a designed video game. We report the results of a mixed-methods study examining the use of this media-based mentoring system with students ages 11 through 14. We observed that the discourse of groups of students that engaged with the game-infused science curriculum while interacting with college student mentors via a social media platform demonstrated statistically significant higher ratings of cognitive, epistemic, and social aspects of argumentation than groups of students that engaged with the social media platform and game-infused science curriculum without mentors. We further explored the differences between the Discourses of the mentored and non-mentored groups. This analysis showed that students in the mentored groups were invited, guided, and socialized into roles of greater agency than students in the non-mentored groups. This increased agency might explain why mentored groups demonstrated higher levels of scientific argumentation than non-mentored groups. Based on our analyses, we argue that media-based mentoring may be designed around a video game to support middle school students in engaging in argumentation from evidence. 相似文献

This study explores the process of teacher scaffolding student engagement in epistemic tools from the critical sensemaking perspective. Epistemic tools are contextual artifacts manipulated to investigate and evaluate ideas to construct knowledge within the constraints of a disciplines' representational means. The main sources of our data are ~50 min-long semistructured, responsive interviews with the 14 secondary school science teachers who participated in our professional learning environment (PLE) and implemented the activities from the PLE in their classrooms. We utilized the tools of discourse analysis to explore teacher sensemaking while they learned to teach science with epistemic tools. We then looked at intertextualities of meaning across multiple sets of data such as students' artifacts, pre/postsurveys, audio and video recordings of the workshops, and teachers' written implementation feedback forms. As a result, we recognized a pattern across different classrooms. Teachers would begin with a contextualized goal, and use a pedagogical strategy to scaffold their students as they worked to achieve that goal. Then, all teachers reported they faced some sort of ambiguity (such as grappling with failure, different levels of students). When faced with an ambiguity, teachers would then revise either their contextualized goal or their initial pedagogical strategy to help their students to reach their goals. Finally, we utilized constant-comparative analysis to identify themes for teachers' contextualized goals. Four major themes emerged, including communicating connections to core ideas of science, making sense of how science works, assessing students' learning process outcomes, and fostering students' epistemic agency. The findings of the study have implications for future research and professional development activities on the use of epistemic practices and tools in classrooms with unique contextual characteristics. 相似文献

Sociocognitive theory [Bandura, A. (1986). Social foundations of thought and action: A social cognitive theory. Englewood Cliffs, NJ: Prentice Hall; Bandura, A. (1989). Human agency in social cognitive theory. American Psychologist, 44, 1175–1184. doi:10.1037/0003-066x.44.9.1175; Bandura, A. (1991). Social cognitive theory of self-regulation. Organizational Behavior and Human Decision Processes, 50, 248–287. doi:10.1016/0749-5978(91)90022-L] accords high importance to the mechanisms of human agency and how they are exercised through self-efficacy. In this paper, we developed and validated the McGill Self-Efficacy For Inquiry Engagement (McSELFIE) instrument with undergraduate students in natural science disciplines. We defined inquiry engagement as carrying out the practices of science (POS) that are supported by students’ personality characteristics (SPCs) and that result in achieving inquiry-learning outcomes (ILOs). Based on these theoretical perspectives, the McSELFIE is a 60-item, learner-focused survey that addresses three components that are theoretically important for engaging in scientific inquiry: (a) SPCs, (b) ILOs, and (c) POS. Evidence for construct and content validity were obtained by using experts’ judgments and confirmatory factor analysis with a sample of 110 undergraduate students enrolled in science disciplines. Internal consistency of the factors and instrument was also examined. The McSELFIE instrument is a reliable and valid instrument for measuring science undergraduate students’ self-efficacy for inquiry engagement. Matched pairs analyses were conducted among the instruments’ factors. Students reported the highest self-efficacy for openness, applying knowledge, and carrying out investigations. Students reported the lowest self-efficacy for extraversion, understanding metacognitive knowledge, and planning investigations. Theoretical and practical implications are discussed. 相似文献

In high‐school chemistry the pre‐experimental phase of inquiry cycles often remains neglected. According to a procedural model, which is described in the text, this phase begins with an observation that stimulates students’ prior factual knowledge, the formulation of a research question for further elaboration (epistemic questions), the anticipation of a hypothetical answer, and the planning of experimental steps for deciding on the hypothetical answer. These activities were explicitly prescribed in an experimental group of 28 10th‐graders. Raising the quality of students’ epistemic research questions by providing structured help was a special focus of the intervention. Hypothesised motivational and cognitive effects were measured and compared with a group of 25 students (control group) who engaged in non‐structured pre‐experimental activities. The intervention provided to the experimental group resulted in stronger preferences for a more open and non‐recipe type of experimentation, in more intense cognitive activities (thoughts), and, most importantly, in increased skills for formulating causal epistemic questions. Supporting such procedural skills in classrooms may contribute to transforming labwork into intentional activities and students into active learners by helping them focus on further elaborating their knowledge. 相似文献

In Continuous Education curricula in Spain, the programs on sciences of the environment are aimed toward understandings of
sustainability. Teaching practice rarely leaves the classroom for outdoor field studies. At the same time, teaching practice
is generally focused on examples of how human activities are harmful for ecosystems. From a pedagogic point of view, it is
less effective to teach environmental science with negative examples such as catastrophe, tragedy, and crisis. Rather, teaching
environmental sciences and sustainable development might be focused on positive human-environment relationships, which is
both important for the further development of students and educators. Within rural settings, there are many such examples
of positive relationships that can be emphasized and integrated into the curriculum. In this article, we propose teaching
environmental sciences through immersion in rural cultural life. We discuss how fieldwork serves as a learning methodology.
When students are engaged through research with traditional cultural practices of environmental management, which is a part
of the real and traditional culture of a region, they better understand how positive pedagogy instead of pedagogy structured
around how not-to-do examples, can be used to stimulate the interactions between humans and the environment with their students.
In this way, cultural goods serve as teaching resources in science and environmental education. What we present is authentic
cases where adults involved in a course of Continuous Education explore ‘environmentally-friendly’ practices of traditional
agriculture in Asturias (north of Spain), employing methodologies of cultural studies. 相似文献

The study examined US elementary teachers’ knowledge and practices in four key domains of science instruction with English language learning (ELL) students. The four domains included: (1) teachers’ knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger five‐year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. It involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first‐year implementation of the intervention. Based on teachers’ questionnaire responses and classroom observation ratings, results indicated that (1) teachers’ knowledge and practices were within the bounds of acceptability but short of reform‐oriented practices and (2) grade‐level differences existed, especially between Grades 3 and 5. 相似文献

Adapted primary literature (APL) is a novel text genre that retains the authentic characteristics of primary literature. Learning
through APL represents an educational intervention with an authentic scientific context. In this case study, we analyzed the
80-min discourse developed during the enactment of an article from an APL-based curriculum in biotechnology in one class,
and examined epistemic practices used by students during their meaning-making of the Results and Discussion sections of the
article. Specifically, we examined coordination practices, by which students connected elements belonging to different epistemic
status or context (theory, data, experimental stages, biotechnological applications and text). The application of coordination
practices was identified more than 70 times during the lesson. In the context of the Results section, the students displayed
research-oriented coordination practices, which were frequently associated with claims of comprehension difficulty. In the
context of the Discussion section, students displayed text-oriented coordination practices, associated with analysis of the
text characteristics. We are suggesting that the research-oriented coordination practices and some of the text-oriented ones
enabled the emergence of authentic scientific practices and learning by inquiry. Another type of text-oriented coordination
practice enabled reflection on scientists’ experimental processes, enabling learning science as inquiry. The enactment model
of APL used here allowed for both the emergence of the two dimensions of inquiry learning and the promotion of scientific
literacy in the fundamental and derived senses. 相似文献

This article examines the stories of 24 social sciences doctoral students in three universities, one in Canada and two in the UK, who experienced challenging roads to completion. While their stories confirm earlier findings, they also provide insight into how students' agency and personal networks of relationships may be critical, both as resources and constraints. We argue that these ‘untold stories’ of student agency coupled with supervisor narratives of students ‘not measuring up’ can contribute to a culture of institutional neglect. Pedagogies emphasizing an ethic of care and relational rather than regulatory practices are essential if these conditions are to change. 相似文献
