This study with 79 students in Montreal, Quebec, compared the educational use of a National Aeronautics and Space Administration (NASA) global climate model (GCM) to climate education technologies developed for classroom use that included simpler interfaces and processes. The goal was to show how differing climate education technologies succeed and fail at getting students to evolve in their understanding of anthropogenic global climate change (AGCC). Many available climate education technologies aim to convey key AGCC concepts or Earth systems processes; the educational GCM used here aims to teach students the methods and processes of global climate modeling. We hypothesized that challenges to learning about AGCC make authentic technology-enabled inquiry important in developing accurate understandings of not just the issue but how scientists research it. The goal was to determine if student learning trajectories differed between the comparison and treatment groups based on whether each climate education technology allowed authentic scientific research. We trace learning trajectories using pre/post exams, practice quizzes, and written student reflections. To examine the reasons for differing learning trajectories, we discuss student pre/post questionnaires, student exit interviews, and 535 min of recorded classroom video. Students who worked with a GCM demonstrated learning trajectories with larger gains, higher levels of engagement, and a better idea of how climate scientists conduct research. Students who worked with simpler climate education technologies scored lower in the course because of lower levels of engagement with inquiry processes that were perceived to not actually resemble the work of climate scientists. 相似文献

Collaboration modality, cognitive load, and science inquiry learning in virtual inquiry environments
Benjamin E. Erlandson Brian C. Nelson Wilhelmina C. Savenye 《Educational technology research and development : ETR & D》2010,58(6):693-710
Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry
curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of
multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to effectively process the rich
information encountered in virtual space. In this study, we investigated the effect of communication modality on cognitive
load and science inquiry learning in students completing a science inquiry curriculum in an educational MUVE. Seventy-eight
undergraduate education majors from a large southwestern university participated in this control-treatment study. Significant
positive results were found for reducing cognitive load for participants communicating through voice-based chat, although
this reduction was not found to influence learning outcomes. We conclude that use of voice-based communication can successfully
reduce cognitive load in MUVE-based inquiry curricula. 相似文献

In this paper, we present a review of research into the problems of implementing authentic scientific inquiry curricula in
schools and the emerging use of educational Multi-User Virtual Environments (MUVEs) to support interactive scientific inquiry
practices. Our analysis of existing literature in this growing area of study reveals three recurrent themes: (1) with careful
design and inclusion of virtual inquiry tools, MUVE-based curricula can successfully support real-world inquiry practices
based on authentic interactivity with simulated worlds and tools, (2) Educational MUVEs can support inquiry that is equally
compelling for girls and boys, and (3) research on student engagement in MUVE-based curricula is uneven. Based on these themes,
we suggest that future large-scale research should investigate (1) the extent to which MUVE-based inquiry learning can be
a viable substitute for the activities involved in real-world inquiry; (2) the impact of MUVEs on learning and engagement
for currently underserved students, and (3) the impact on engagement and learning of individual aspects of MUVE environments,
particularly virtual experimentation tools designed to scaffold student inquiry processes and maintain engagement. Additionally,
we note that two identified issues with integrating scientific inquiry into the classroom are currently not addressed by MUVE
research. We urge researchers to investigate whether (1) MUVE-based curriculum can help teachers meet state and national standards
with inquiry curricula; and (2) scientific inquiry curricula embedded in MUVE environments can help teachers learn how to
integrate interactive scientific inquiry into their classroom.

ABSTRACTMany science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed. 相似文献

Collaborations between the K-12 teachers and higher education or professional scientists have become a widespread approach to science education reform. Educational funding and efforts have been invested to establish these cross-institutional collaborations in many countries. Since 2006, Taiwan initiated the High Scope Program, a high school science curriculum reform to promote scientific innovation and inquiry through an integration of advanced science and technology in high school science curricula through partnership between high school teachers and higher education scientists and science educators. This study, as part of this governmental effort, a scientist–teacher collaborative model (STCM) was constructed by 8 scientists and 4 teachers to drive an 18-week high school science curriculum reform on environmental education in a public high school. Partnerships between scientists and teachers offer opportunities to strengthen the elements of effective science teaching identified by Shulman and ultimately affect students’ learning. Mixed methods research was used for this study. Qualitative methods of interviews were used to understand the impact on the teachers’ and scientists’ science teaching. A quasi-experimental design was used to understand the impact on students’ scientific competency and scientific interest. The findings in this study suggest that the use of the STCM had a medium effect on students’ scientific competency and a large effect on students’ scientific individual and situational interests. In the interviews, the teachers indicated how the STCM allowed them to improve their content knowledge and pedagogical content knowledge (PCK), and the scientists indicated an increased knowledge of learners, knowledge of curriculum, and PCK. 相似文献

青少年学生群体是我国未来科学发展的储备力量,科学家是科学技术行业的精英形象代表。青少年学生心目中的科学家形象影响着他们科学学习的兴趣和与科学相关职业的认同。实证研究表明,青少年学生所认知的科学家形象总体上较为刻板。以社会建构主义的视角可以看到,这种刻板印象的认知受到其所处的社会文化情境的影响,也存在着文化的差异性。为了树立科学家在学生群体中的积极、正面和可及性形象,提供科学家的榜样角色和提供与科学职业有关的信息是两个重要的途径。针对我国科学教育现状,在向青少年学生传播和塑造科学家形象的过程中,应注意科学研究与科学传播、科普研究与科普实践、主流群体与边缘群体、自然科学与社会科学等的相互结合。 相似文献

ABSTRACTScience education trends promote student engagement in authentic knowledge in practice to tackle personally consequential problems. This study explored how partnering scientists and students on a social media platform supported students’ development of disciplinary practice knowledge through practice-based learning with experts during two pilot enactments of a project-based curriculum focusing on the ecological impacts of climate change. Through the online platform, scientists provided feedback on students' infographics, visual argumentation artifacts that use data to communicate about climate change science. We conceptualize the infographics and professional data sets as boundary objects that supported authentic argumentation practices across classroom and professional contexts, but found that student generated data was not robust enough to cross these boundaries. Analysis of the structure and content of the scientists’ feedback revealed that when critiquing argumentation, scientists initiated engagement in multiple scientific practices, supporting a holistic rather than discrete model of practice-based learning. While traditional classroom inquiry has emphasized student experimentation, we found that engagement with existing professional data sets provided students with a platform for developing expertise in systemic scientific practices during argument construction. We further found that many students increased the complexity and improved the visual presentation of their arguments after feedback. 相似文献

This study examined the relationships that exist between high school science teachers' understanding of the Piagetian developmental model of intelligence, its inherent teaching procedure—the learning cycle—and classroom teaching practices. The teachers observed in this study had expressed dissatisfaction with the teaching methods they used, and, subsequently, attended a National Science Foundation sponsored in-service program designed to examine laboratory-centered science curricula and the educational and scientific theories upon which the curricula were based. The teachers who exhibited a sound understanding of the Piagetian model of intelligence and the learning cycle were more likely to effectively implement learning cycle curricula. They were able to successfully integrate their students' laboratory experiences with class discussions to construct science concepts. The teachers who exhibited misunderstandings of the Piagetian developmental model of intelligence and the learning cycle also engaged their students in laboratory activities, but these activities were weakly related to learning cycles. For example, the data gathered by their students were typically not used in class discussions to construct science concepts. Therefore, these teachers apparently did not discern the necessity of using the data and experiences from laboratory activities as the impetus for science concept attainment. Additional results comparing degrees of understanding, teaching behaviors and questioning strategies are discussed. 相似文献

Written in response to criticism of our work by Fouad Abd-El-Khalick, this position paper reaffirms and reinforces our position about the need to broaden and enrich the scope of nature of science (NOS) oriented curricula by exposing students to the voices of practising scientists. While Abd-El-Khalick's motivation for promoting the so-called consensus view of NOS is rooted in issues of assessment (or ‘benchmarking', as he calls it), we argue that the major reason for teaching about NOS is its contribution to what Shen calls civic and cultural scientific literacy. We are critical of the consensus view for its philosophical naivety, failure to reflect contemporary scientific practice and potential for confusing students, and we re-state our view that it is important to expose students to a diversity of practice among the sub-disciplines of science. We argue that richer NOS understanding and a more authentic view of scientific practice can be achieved through direct and indirect contact with scientists at the cutting edge of research and development, which we characterise as learning about scientists, learning from scientists and learning with scientists. 相似文献

This paper reports on the reality of classroom‐based inquiry learning in science, from the perspectives of high school students and their teachers, under a national curriculum attempting to encourage authentic scientific inquiry (as practiced by scientists). A multiple case study approach was taken, utilising qualitative research methods of unobtrusive observation, semi‐structured interviews and document analysis. The findings showed purposeful and focused learning occurring, but students were acquiring a narrow view of scientific inquiry where the thinking was characteristically rote and low‐level. The nature of this learning was strongly influenced by curriculum decisions made by classroom teachers and science departments in response to the assessment requirements of a high stakes national qualification. As a consequence of these decisions, students experienced structured teaching programmes in which they were exposed to programme content that limited the range of methods that scientists use to fair testing and to pedagogies that were substantially didactic in nature. In addition, the use of planning templates and exemplar assessment schedules tended to reduce student learning about experimental design to an exercise in “following the rules” as they engaged in closed rather than open investigations. Thus, the resulting student learning was mechanistic and superficial rather than creative and critical, counter to the aims of the national curriculum policy that is intent on promoting students’ knowledge and capabilities in authentic scientific inquiry. 相似文献

This study addresses the need for research in three areas: (1) teachers' understandings of scientific inquiry; (2) conceptual understandings of evolutionary processes; and (3) technology‐enhanced instruction using an inquiry approach. The purpose of this study was to determine in what ways The Galapagos Finches software–based materials created a context for learning and teaching about the nature of scientific knowledge and evolutionary concepts. The research used a design experiment in which researchers significantly modified a secondary science methods course. The multiple data sources included: audiotaped conversations of two focus pairs of participants as they interacted with the software; written pre‐ and posttests on concepts of natural selection of the 21 prospective teachers; written pre‐ and posttests on views of the nature of science; three e‐mail journal questions; and videotaped class discussions. Findings indicate that prospective teachers initially demonstrated alternative understandings of evolutionary concepts; there were uninformed understandings of the nature of scientific inquiry; there was little correlation between understandings and disciplines; and even the prospective teachers with research experience failed to understand the diverse methods used by scientists. Following the module there was evidence of enhanced understandings through metacognition, and the potential for interactive software to provide promising context for enhancing content understandings. © 2005 Wiley Periodicals, Inc. 相似文献

Over the last two decades, science educators and science education researchers have grown increasingly interested in utilising insights from the sociology of scientific knowledge (SSK) to inform their work and research. To date, researchers in science education have focused on two applications: results of sociological studies of science have been used to define new areas of content, generally referred to as Nature of Science (NOS). This has included research into students’ understanding of the NOS, teachers’ understanding of the NOS, and inclusion (or exclusion) of NOS themes in curricula. A second vein of inquiry has been investigations that consider the classroom as a microcosm of scientific discourse and inquiry. Such research has included investigations of student‐to‐student and student‐to‐teacher interactions. In this paper, we present a third application for educational research – the investigation of teacher knowledge and practice as sociological phenomena. In addition to supporting scholarly research, we believe it can be a useful tool for illuminating the complexities of teaching that needs to be taken into account by policy makers and practitioners. In this paper, we provide a thematic review of concepts from the sociology of scientific knowledge, and their application to a case of teacher work. 相似文献

In this study, a wiki was integrated into a professional development model that systemically addresses early-career teachers?? needs. This study was conducted to examine the impact of wiki-based professional development activities in a scientist-teacher professional learning community and focused on early-career teachers?? perceptions of the role of wiki technology and knowledge of teaching through inquiry. Teachers participated in the Professional Learning Community Model for Entry into Teaching Science (PLC-METS), a professional development program that is based on an integrated teacher education model of knowledge sharing, collaboration, and communication between teachers and scientists, with the goal of supporting early-career teachers?? ability to engage their students in scientific inquiry. The use of a wiki environment to collaborate on activities, deliver resources, and share knowledge is rapidly expanding in professional development communities. The use of the wiki in PLC-METS positively predicted the results of teachers?? knowledge of inquiry-based teaching. Results demonstrate that the wiki can contribute to building a learning community for collaboration between early-career science teachers and scientists. The paper also discusses the educational implications for the design of wiki-based professional learning communities that impact teachers?? professional development. 相似文献

A science teacher and her mentor reflect on their participation in the Learning Research Cycle, a professional learning model
that bridges research and practice in both university and public school contexts. Teachers do scientific research in scientists’
laboratories, then bridge their scientific experiences with the design of new classroom learning environments and teacher-driven
educational research projects. Science students do scientific research via their teachers’ lessons that bridge laboratory
research with classroom learning. Scientists and educational researchers bridge their research interests to create new questions
centered on teaching and learning in authentic science learning environments. The authors engaged in this qualitative inquiry
present their perspectives on “what goes on,” “what we have learned,” and “what it means to the larger community.” 相似文献

Responsible Research and Innovation (RRI) is a contemporary approach to promote science with and for society for aligning scientific innovations with societal needs. Literature about education for RRI is limited because it is not a widespread practice at the moment. To explore this gap, this study examines teachers’ views about a novel inquiry game with Augmented Reality to foster inquiry skills for RRI. This game about Genetic-Modified food was used by 18 educators from Secondary and Higher Education who engaged 390 students to form opinions about risks and benefits of GM cereal. The thematic analysis of qualitative data: semi-structured questionnaires, teaching reports and focus groups, revealed motivations and practices that influence teachers’ adoption of OER created with new technologies. Findings revealed that the 3-phase-model approach used in the game engaged students to “CARE” about global issues, “KNOW” science concepts and “DO” actions through an active open schooling network. The key drivers for educators’ adoption of AR inquiry games are to make learning more meaningful and engaging through students-centred approaches and topical resources for them to develop scientific knowledge and skills. However, the key requirements for that are easy-to-use technologies and pedagogical strategies for identifying learner’s achievements and difficulties. 相似文献

This study explored practicing elementary school teacher’s conceptions of teaching in ways that foster inquiry-based learning
in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the
principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should
be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent
educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning
as a referent for teaching still struggles to find expression in the average teachers’ pedagogy. This study drew on interview
data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning
in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing
interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students
with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and
answer their own questions. Understanding teachers’ conceptions has implications for both the enactment of inquiry teaching
in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for
engaging students in Science. 相似文献

Although classroom inquiry is the primary pedagogy of science education, it has often been difficult to implement within conventional classroom cultures. This study turned to the alternatively structured Montessori learning environment to better understand the ways in which it fosters the essential elements of classroom inquiry, as defined by prominent policy documents. Specifically, we examined the opportunities present in Montessori classrooms for students to develop an interest in the natural world, generate explanations in science, and communicate about science. Using ethnographic research methods in four Montessori classrooms at the primary and elementary levels, this research captured a range of scientific learning opportunities. The study found that the Montessori learning environment provided opportunities for students to develop enduring interests in scientific topics and communicate about science in various ways. The data also indicated that explanation was largely teacher-driven in the Montessori classroom culture. This study offers lessons for both conventional and Montessori classrooms and suggests further research that bridges educational contexts. 相似文献

This research addresses the effectiveness of an interactive learning environment, Inquiry Island, as a general-purpose framework
for the design of inquiry-based science curricula. We introduce the software as a scaffold designed to support the creation
and assessment of inquiry projects, and describe its use in a middle-school genetics unit. Students in the intervention showed
significant gains in inquiry skills. We also illustrate the power of the software to gather and analyze qualitative data about
student learning. 相似文献

The purpose of this study was to examine whether Socioscientific Issues (SSI) based learning environments affect university students’ epistemological understanding of scientific inquiry differently from traditional science educational contexts. We identify and compare conceptions of scientific inquiry of students participating in an interdisciplinary, SSI-focused undergraduate human biology major (SSI) and those participating in a traditional biology major (BIO). Forty-five SSI students and 50 BIO students completed an open-ended questionnaire examining their understanding of scientific inquiry. Eight general themes including approximately 60 subthemes emerged from questionnaire responses, and the numbers of students including each subtheme in their responses were statistically compared between groups. A subset of students participated in interviews, which were used to validate and triangulate questionnaire data and probe students’ understanding of scientific inquiry in relation to their majors. We found that both groups provided very similar responses, differing significantly in only five subthemes. Results indicated that both groups held generally adequate understandings of inquiry, but also a number of misconceptions. Small differences between groups supported by both questionnaires and interviews suggest that the SSI context contributed to nuanced understandings, such as a more interdisciplinary and problem-centered conception of scientific inquiry. Implications for teaching and research are discussed. 相似文献
