The environmental education (EE) field has encountered persistent challenges in fostering the integration of EE practices in public schools, a challenge that may be addressed through integration of EE with the Next Generation Science Standards (NGSS) in the United States. In addition to the potential for fostering EE, the integration of EE and NGSS may provide a unique set of conditions for understanding how and why teachers shift their practice to incorporate more EE in their classrooms. Using a mixed methodology research design, this study examines the outcomes and processes of a professional development institute that integrated NGSS and student-driven environmental stewardship. This study provides evidence that integrating NGSS Science and Engineering Practices with stewardship may help infuse EE into classrooms. The research also contributes to theoretical understanding of the processes by which professional development shapes teacher change within an organizational context. Specifically, teacher instructional change was predicated on a shift in their beliefs that stewardship was possible in a standards and accountability-based educational context. The requisite shift in beliefs came about through the expectations and supportive resources provided by the professional development, teacher observation of student engagement, and the justification NGSS integration provided for stewardship activities.  相似文献

The purpose of this paper is to describe how the environment and environmental issues are conceptualized and positioned in the Next Generation Science Standards (NGSS) to examine underlying assumptions about the environment. The NGSS are a recent set of science standards in the USA, organized and led by Achieve Inc., that propose science education goals based on the National Research Council report, A Framework for K-12 Science Education. Drawing from critical discourse analysis, we present a detailed textual analysis of the NGSS to identify the positioning of the environment with respect to humans and human activity. This analysis shows patterns in the ways that the environment is conceptualized and inscribed in the standards as an entity separate from people through both exclusion and ambiguity. We also discuss findings about how agency is more often ascribed to actions or activities rather than people and when solutions to environmental issues are included, the focus is on technoscientific solutions. Finally, we provide implications for considering scientific and environmental literacy, education for action, and the role of standards documents in shaping educational practice.  相似文献

For students to achieve the goals of the Next Generation Science Standards (NGSS) by Grade 12, thinking and acting like scientists and engineers must begin in the elementary grades. However, elementary teachers may find this challenging -because language arts and mathematics still dominate many classrooms—often at the expense of science. This essay examines the science skills elementary students are expected to learn and how teachers and administrators can approach the increased demands of NGSS.  相似文献

NGSS and the Next Generation of Science Teachers   总被引：1，自引：0，他引：1  
This article centers on the Next Generation Science Standards (NGSS) and their implications for teacher development, particularly at the undergraduate level. After an introduction to NGSS and the influence of standards in the educational system, the article addresses specific educational shifts—interconnecting science and engineering practices, disciplinary core ideas, crosscutting concepts; recognizing learning progressions; including engineering; addressing the nature of science, coordinating with Common Core State Standards. The article continues with a general discussion of reforming teacher education programs and a concluding discussion of basic competencies and personal qualities of effective science teachers.  相似文献

Abstract

This case study presents the efforts of three high school teachers to design and implement climate change lessons in alignment with the Next Generation Science Standards (NGSS). Using three conceptual frameworks that organize the assumptions of the environment in the NGSS we examine how those assumptions influence teacher practice when teachers strive to align with the standards. Video recorded instruction of eight climate change-anchored lessons spanning three consecutive years were thematically coded. Results indicate that the problematic aspects of the NGSS’s characterization of climate change can help explain the framing of environmental issues and the compartmentalization of humans relative to the climate science in teachers’ lesson plans and instruction. The NGSS promulgate disconnected agency which appears in teacher and student talk in classrooms. Our analysis reveals opportunities to use standards to design interventions for classroom practice to support diverse students in countering the assumptions about the human-environment relationship embodied in the NGSS.  相似文献

This study investigated the degree that Science and Engineering Practices (SEPs) criteria from the Next Generation Science Standards (NGSS) were included in self-reported teaching practices of twelfth-grade science teachers in Jordan. This study sampled (n?=?315) science teachers recruited from eight different public school directorates. The sample was surveyed using an instrument adapted from Kawasaki (2015). Results found that Jordanian science teachers incorporate (SEPs) in their classroom teaching at only a moderate level. SEPs applied most frequently included ‘using the diagram, table or graphic through instructions to clarify the subject of a new science,’ and to ‘discuss with the students how to interpret the quantitative data from the experiment or investigation’. The practice with the lowest frequency was ‘teach a lesson on interpreting statistics or quantitative data,’ which was moderately applied. No statistically significant differences at (α?=?0.05) were found among these Jordanian science teachers’ self-estimations of (SEP) application into their own teaching according to the study’s demographic variables (specialisation, educational qualification, teaching experience). However, a statistically significant difference at (α?=?0.05) was found among Jordanian high school science teachers’ practice means based on gender, with female teachers using SEPs at a higher rate than male teachers.  相似文献

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. This research explored: (1) how the program affects student understanding of scientific inquiry and research and (2) how the open-inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.  相似文献

The Next Generation Science Standards (NGSS) strives to shift science learning from the teacher as a single cognitive agent, to a classroom community in which participants are working together in directing the classroom's communal knowledge to figure out questions about how phenomena occur, and building, testing, and refining their ideas to address those questions. To achieve this type of classroom environment, teachers should attend to students' knowledge and ideas and pay attention to how students are located within teacher-led interactions, such as being positioned as active discussants or designated listeners. In this study, we explore if and how this is occurring in the NGSS era. We used a naturalistic inquiry to explore how an experienced first-grade teacher used a new NGSS-aligned unit that called for students to use the science and engineering practices (SEP) to build content knowledge. We used a macro-analytic lens to answer the research question “how are class discussions shaped to address the SEP”? We used a micro-analytic lens to answer the research question “how are students positioned during these science discussions in this classroom?” Evidence suggests that the teachers' whole class discussions incorporated and involved the SEP which were specified in the unit lessons for content learning. However, on a micro-analytic level, we found that few students were positioned as active discussants. The teacher heavily relied on those students who could provide succinct and clearly relevant answers while positioning the remainder of the students as silent spectators. Implications from this research suggest that not only new NGSS curriculum materials need to focus on what students should know and do but they also need to address heuristics for teachers that show them how to position all of their students as active doers of science so all students have opportunities to build deeper, core science knowledge.  相似文献

We find ourselves at a time when the need for transformation in science education is aligning with opportunity. Significant science education resources, namely the Next Generation Science Standards (NGSS) and the Ambitious Science Teaching (AST) framework, need an intentional aim of centering social justice for minoritized communities and youth as well as practices to enact it. While NGSS and AST provide concrete guidelines to support deep learning, revisions are needed to explicitly promote social justice. In this study, we sought to understand how a commitment to social justice, operationalized through culturally sustaining pedagogy (Paris, Culturally sustaining pedagogies and our futures. The Educational Forum, 2021; 85, pp. 364–376), might shape the AST framework to promote more critical versions of teaching science for equity. Through a qualitative multi-case study, we observed three preservice teacher teams engaged in planning, teaching, and debriefing a 6-day summer camp in a rural community. Findings showed that teachers shaped the AST sets of practices in ways that sustained local culture and addressed equity aims: anchoring scientific study in phenomena important to community stakeholders; using legitimizing students' stories by both using them to plan the following lessons and as data for scientific argumentation; introducing local community members as scientific experts, ultimately supporting a new sense of pride and advocacy for their community; and supporting students in publicly communicating their developing scientific expertise to community stakeholders. In shaping the AST framework through culturally sustaining pedagogy, teachers made notable investments: developing local networks; learning about local geography, history, and culture; building relationships with students; adapting lessons to incorporate students' ideas; connecting with community stakeholders to build scientific collaborations; and preparing to share their work publicly with the community. Using these findings, we offer a justice-centered ambitious science teaching (JuST) framework that can deliver the benefits of a framework of practices while also engaging in the necessarily more critical elements of equity work.  相似文献

Contemporary policy statements from government and reforms to science curricula in schools emphasise the importance of educating a scientifically literate public for democratic participation in science and technology. While such an aspiration is seemingly uncontentious and appears consistent with progressive educational thinking, the reality of democratic participation is problematic. I propose four frameworks for describing democratic participation in schools. The first two – deficit and deliberative democracy – fulfil a limited role for democratic participation. ‘Science education as praxis’ and ‘science education for conflict and dissent’ present more radical programmes but reflect tensions with the dominant discourse of scientific literacy and citizenship as reflected in school curricula. To operationalise aspects of democratic participation, teachers need to make explicit the role of scientific knowledge and decision‐making within each framework. While radical change is likely to meet with resistance, this process will in turn generate new discourses about the problems and opportunities of democratic participation.  相似文献

Engineering is featured prominently in the Next Generation Science Standards (NGSS) and related reform documents, but how its nature and methods are described is problematic. This paper is a systematic review and critique of that representation, and proposes that the disciplinary core ideas of engineering (as described in the NGSS) can be disregarded safely if the practices of engineering are better articulated and modeled through student engagement in engineering projects. A clearer distinction between science and engineering practices is outlined, and prior research is described that suggests that precollege engineering design can strengthen children’s understandings about scientific concepts. However, a piecemeal approach to teaching engineering practices is unlikely to result in students understanding engineering as a discipline. The implications for science teacher education are supplemented with lessons learned from a number of engineering education professional development projects.  相似文献

Instruments measuring understanding of the nature of science (NOS) are required if educational institutions intend to use benchmarks or examine the effects of interventions targeting students’ NOS development. Compared to other constructs, NOS understanding is complex, having been the subject of debate among scholars in both its substance and its dimensionality. This complexity invites challenges in defining what is to be measured. Drawing from the perspective that policy reform documents provide pragmatic consensus-based definitions of NOS, this study investigated how well the dimensionality described in the NOS component of the Next Generation Science Standards (NGSS) framework matched the empirical structure of data collected from a set of secondary-school students’ responses to an NOS instrument comprising multiple-choice and Likert-scale items. Using multidimensional item response modeling to compare structures of NOS dimensionality, we found that treating NOS as comprising multiple dimensions—as defined by the themes in the NGSS NOS framework—resulted in a better fitting model than when treating NOS as a single dimension. The multidimensional model also had fewer poorly functioning items and revealed NOS profiles that otherwise would have been masked in a model treating NOS as a single dimension. These results provide support for the NOS NGSS framework and contribute to the ongoing discussion about the dimensionality of NOS.  相似文献

This paper reports the procedure and results of a study analyzing Science-Technology-Society (STS) themes in state science curriculum frameworks in the United States. The criteria for the analysis consisted of 15 categories of standards derived from the K–12 content standards of the National Science Education Standards. Out of the 25 state science curriculum frameworks analyzed, 88% emphasized the standard Science and technology in society. Three standards (Environmental quality, Science as a human endeavor, and Nature of science and scientific knowledge) were represented in nearly 50% of the state science curriculum frameworks. The remaining 11 content standards were scarcely represented in the state science curriculum frameworks analyzed. The recommendations of this study include an examination of educational policy links to state science frameworks, and case studies of curriculum policy-to-practice transition in STS education.  相似文献

This paper explores the ambivalence of the Next Generation Science Standards (NGSS) and its Framework towards neoliberal governance. The paper examines the ways that the NGSS serves as a mechanism within neoliberal governance: in its production of disposable populations through testing and through the infusion of engineering throughout the NGSS to resolve social problems through technical fixes. However, the NGSS, like earlier standards, is reactionary to forces diminishing the power of institutional science (e.g., the AAAS) including neoliberal prioritizing market value over evidence. The NGSS explicitly takes on neoliberal junk science such as the anti-global-warming Heartland Institute.  相似文献

Beginning in January of 2010, the Carnegie Corporation of New York funded a two-step process to develop a new set of state developed science standards intended to prepare students for college and career readiness in science. These new internationally benchmarked science standards, the Next Generation Science Standards (NGSS) were completed in April of 2013. From his perspective as the coordinator of the development of the NGSS, the author discusses the background regarding the development, key features and some of the challenges ahead in implementing the NGSS.  相似文献

Ambitious efforts are taking place to implement a new vision for science education in the United States, in both Next Generation Science Standards (NGSS)-adopted states and those states creating their own, often related, standards. In-service and pre-service teacher educators are involved in supporting teacher shifts in practice toward the new standards. With these efforts, it will be important to document shifts in science instruction toward the goals of NGSS and broader science education reform. Survey instruments are often used to capture instructional practices; however, existing surveys primarily measure inquiry based on previous definitions and standards and with a few exceptions, disregard key instructional practices considered outside the scope of inquiry. A comprehensive survey and a clearly defined set of items do not exist. Moreover, items specific to the NGSS Science and Engineering practices have not yet been tested. To address this need, we developed and validated a Science Instructional Practices survey instrument that is appropriate for NGSS and other related science standards. Survey construction was based on a literature review establishing key areas of science instruction, followed by a systematic process for identifying and creating items. Instrument validity and reliability were then tested through a procedure that included cognitive interviews, expert review, exploratory and confirmatory factor analysis (using independent samples), and analysis of criterion validity. Based on these analyses, final subscales include: Instigating an Investigation, Data Collection and Analysis, Critique, Explanation and Argumentation, Modeling, Traditional Instruction, Prior Knowledge, Science Communication, and Discourse.  相似文献
