Teaching Engineering Practices

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.     

Positioning participation in the NGSS era: What counts as success?

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.     

Teachers’ Integration of Scientific and Engineering Practices in Primary Classrooms

The Next-Generation Science Standards (NGSS) challenge primary teachers and students to work and think like scientists and engineers as they strive to understand complex concepts. Teachers and teacher educators can leverage what is already known about inquiry teaching as they plan instruction to help students meet the new standards. This cross-case analysis of a multiple case study examined teacher practices in the context of a semester-long professional development course for elementary teachers. We reviewed lessons and teacher reflections, examining how kindergarten and first grade teachers incorporated NGSS scientific and engineering practices during inquiry-based instruction. We found that most of the teachers worked with their students on asking questions; planning and carrying out investigations; analyzing and interpreting data, using mathematics and computational thinking; and obtaining, evaluating and communicating information. Teachers faced challenges in supporting students in developing their own questions that could be investigated and using data collection strategies that aligned with students’ development of number sense concepts. Also, some teachers overemphasized the scientific method and lacked clarity in how they elicited and responded to student predictions. Discussion focuses on teacher supports that will be needed as states transition to NGSS.     

Teachers’ uptake of problematic assumptions of climate change in the NGSS

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.     

Measuring Pedagogy and the Integration of Engineering Design in STEM Classrooms

The present study examined changes in high school biology and technology education pedagogy during the first year of a three-year professional development (PD) program using the INSPIRES educative curriculum. The Next Generation Science Standards (NGSS) calls for the integration of science and engineering through inquiry-based pedagogy that shifts the burden of thinking from the teacher to the student. This call is especially challenging for teachers untrained in inquiry teaching and engineering or science concepts. The INSPIRES educative curriculum materials and PD provided a mechanism for teachers to transform their teaching to meet the NGSS challenges. This study followed a longitudinal triangulation mixed methods design. Selected lessons were video recorded, scored on the Reformed Teaching Observation Protocol (RTOP) rubric, and examined for qualitative trends. Year 1 results indicated that teachers had begun to transform their teaching and pointed to particular lessons within the INSPIRES curriculum that most facilitated the reform. Instructional practices of participants improved significantly as a result of the INSPIRES PD program and also aligned with previous, similar studies. These findings provide insights for rethinking the structure of professional development, particularly in the integrated use of an educative curriculum aligned with intended professional development goals.

     

Individualism,instrumental reason and policy texts: some considerations from the perspective of contemporary political philosophy

This article dialogues with Matthew Weinstein’s paper named “NGSS, disposability, and the ambivalence of Science in/under neoliberalism”, in which he explores the argument that at the same time the NGSS framework is largely identified with neoliberal discourse, it presents points of ambivalence and resistance within. In this dialogue, we focused on two topics that we believe are important for the discussion of the ambivalences highlighted in the author’s argument, namely: the the social production of indifference as a consequence of the neoliberal ideology and the production of a version of science streamlined for the neoliberal technoscientific job market within the ‘neoliberal ecosystem’. Based on the thesis of the Canadian philosopher Charles Taylor on ethics and on the concept of hybridism, we linked Weinsteins’ analysis to issues related to individualism and instrumental reason, pointing out that it is possible that the ambivalences highlighted by Weinstein are, in fact, a component of neoliberal discourse. Nevertheless we agree that this kind of text presents loopholes that allows practices oriented for social change and for the improvement of democracies in progress. We conclude that for those who dedicate themselves to reflect upon educational strategies to cope with the hegemonic model remains the challenge of finding spaces and times in the curriculum in order to explore the gaps in policy texts and, more important, to promote the experience of democratic practices throughout the school communities.     

Understanding teacher instructional change: the case of integrating NGSS and stewardship in professional development

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.     

Measuring Science Instructional Practice: A Survey Tool for the Age of NGSS

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.     

Teachers' learning to facilitate high‐level student thinking: Impact of a video‐based professional development

Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms.     

Learning from the Professions: Examining How,Why, and When Engineers Read and Write

With the advent of the Next Generation Science Standards in engineering (NGSS, 2013), teachers of multiple subject areas are being asked to do more than ever before—not only to teach engineering content in the K-12 classroom but also to engage students in authentic disciplinary reading and writing as part of content learning. These standards sound good, but they beg several questions; namely, what do we know about how, why, and when do engineers read and write as they do their work every day? What do teachers charged with engineering education know about the daily practices of engineers, let alone the literacy practices? In short, little is known about the literacy practices of engineers in the course of their daily work. This article draws on participant observation, interviews, and document analysis of one research engineering laboratory to illustrate the literacy practices of one group of engineers and begins to draw implications from this work for teacher practice in achieving the NGSS engineering education standards.     

The Nature of Science and the <Emphasis Type="Italic">Next Generation Science Standards</Emphasis>: Analysis and Critique

This paper provides a detailed analysis of the inclusion of aspects of nature of science (NOS) in the Next Generation Science Standards (NGSS). In this new standards document, NOS elements in eight categories are discussed in Appendix H along with illustrative statements (called exemplars). Many, but not all, of these exemplars are linked to the standards by their association with either the “practices of science” or “crosscutting concepts,” but curiously not with the recommendations for science content. The study investigated all aspects of NOS in NGSS including the accuracy and inclusion of the supporting exemplar statements and the relationship of NOS in NGSS to other aspects of NOS to support teaching and learning science. We found that while 92 % of these exemplars are acceptable, only 78 % of those written actually appear with the standards. “Science as a way of knowing” is a recommended NOS category in NGSS but is not included with the standards. Also, several other NOS elements fail to be included at all grade levels thus limiting their impact. Finally, NGSS fails to include or insufficiently emphasize several frequently recommended NOS elements such as creativity and subjectivity. The paper concludes with a list of concerns and solutions to the challenges of NOS in NGSS.     

NGSS,disposability, and the ambivalence of science in/under neoliberalism

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.     

Enhancing use of learning sciences research in planning for and supporting educational change: Leveraging and building social networks

This paper explores practical ways to engage two areas of educational scholarship—research on science learning and research on social networks—to inform efforts to plan and support implementation of new standards. The standards, the Next Generation Science Standards (NGSS; NGSS Lead States in Next generation science standards: For states, by states. National Academies Press, Washington, DC, 2013), have been adopted by U.S. states serving more than one-quarter of all students, and they are grounded in decades of research on how students learn science. In this paper we discuss efforts to leverage recent research on social networks to inform standards implementation across a set of professional associations and school districts. These efforts are being undertaken by the Research + Practice Collaboratory which is testing a set of conjectures related to how the knowledge base from both research and practice can mutually inform STEM education improvement.     

Comparing Models of Nature of Science Dimensionality Based on the Next Generation Science Standards

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.     

How the environment is positioned in the Next Generation Science Standards: a critical discourse analysis

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.     

Effects of 3D Printing Project-based Learning on Preservice Elementary Teachers’ Science Attitudes,Science Content Knowledge,and Anxiety About Teaching Science

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.     

Engineering design skills coverage in K-12 engineering program curriculum materials in the USA

ABSTRACT

The current K-12 Science Education framework and Next Generation Science Standards (NGSS) in the United States emphasise the integration of engineering design in science instruction to promote scientific literacy and engineering design skills among students. As such, many engineering education programmes have developed curriculum materials that are being used in K-12 settings. However, little is known about the nature and extent to which engineering design skills outlined in NGSS are addressed in these K-12 engineering education programme curriculum materials. We analysed nine K-12 engineering education programmes for the nature and extent of engineering design skills coverage. Results show that developing possible solutions and actual designing of prototypes were the highly covered engineering design skills; specification of clear goals, criteria, and constraints received medium coverage; defining and identifying an engineering problem; optimising the design solution; and demonstrating how a prototype works, and making iterations to improve designs were lowly covered. These trends were similar across grade levels and across discipline-specific curriculum materials. These results have implications on engineering design-integrated science teaching and learning in K-12 settings.     

The Intersection of Inquiry-Based Science and Language: Preparing Teachers for ELL Classrooms

As teacher educators, we are tasked with preparing prospective teachers to enter a field that has undergone significant changes in student population and policy since we were K-12 teachers. With the emphasis placed on connections, mathematics integration, and communication by the New Generation Science Standards (NGSS) (Achieve in Next generation science standards, 2012), more research is needed on how teachers can accomplish this integration (Bunch in Rev Res Educ 37:298–341, 2013; Lee et al. in Educ Res 42(4):223–233, 2013). Science teacher educators, in response to the NGSS, recognize that it is necessary for pre-service and in-service teachers to know more about how instructional strategies in language and science can complement one another. Our purpose in this study was to explore a model of integration that can be used in classrooms. To do this, we examined the change in science content knowledge and academic vocabulary for English language learners (ELLs) as they engaged in inquiry-based science experience utilizing the 5R Instructional Model. Two units, erosion and wind turbines, were developed using the 5R Instructional Model and taught during two different years in a summer school program for ELLs. We analyzed data from interviews to assess change in conceptual understanding and science academic vocabulary over the 60 h of instruction. The statistics show a clear trend of growth supporting our claim that ELLs did construct more sophisticated understanding of the topics and use more language to communicate their knowledge. As science teacher educators seek ways to prepare elementary teachers to help preK-12 students to learn science and develop the language of science, the 5R Instructional Model is one pathway.
