Students build up their STEM career interest based on their experiences. However, it remains unclear how students reflect on their STEM experiences in light of their understanding of STEM careers. This study aimed to explore how students relate their practices in STEM project-based learning (PBL) with their perceptions of scientists’ and engineers’ work. A randomly selected sample of students (n =142) participating in a STEM event participated in structured interviews regarding the resemblance between their months-long STEM PBL and scientists’ and engineers’ work. The data were coded using content analysis mostly by adopting a bottom-up approach followed by statistical analysis. Results showed that the majority of students claimed that their group had done things like scientists, while only about half of the students acknowledged doing things like engineers. The number and aspects of the students’ mentioned practices were generally limited, with engineer-like practices more divergent and reflecting their stereotype of engineers working as manual laborers. The results also suggest that students tend to neglect the minds-on but hands-off scientist- or engineer-like practices such as raising a question/problem. The findings address the research gap regarding how students reflect on their STEM PBL experiences in light of career development.

Background The use of visual representations (i.e., photographs, diagrams, models) has been part of science, and their use makes it possible for scientists to interact with and represent complex phenomena, not observable in other ways. Despite a wealth of research in science education on visual representations, the emphasis of such research has mainly been on the conceptual understanding when using visual representations and less on visual representations as epistemic objects. In this paper, we argue that by positioning visual representations as epistemic objects of scientific practices, science education can bring a renewed focus on how visualization contributes to knowledge formation in science from the learners’ perspective. Results This is a theoretical paper, and in order to argue about the role of visualization, we first present a case study, that of the discovery of the structure of DNA that highlights the epistemic components of visual information in science. The second case study focuses on Faraday’s use of the lines of magnetic force. Faraday is known of his exploratory, creative, and yet systemic way of experimenting, and the visual reasoning leading to theoretical development was an inherent part of the experimentation. Third, we trace a contemporary account from science focusing on the experimental practices and how reproducibility of experimental procedures can be reinforced through video data. Conclusions Our conclusions suggest that in teaching science, the emphasis in visualization should shift from cognitive understanding—using the products of science to understand the content—to engaging in the processes of visualization. Furthermore, we suggest that is it essential to design curriculum materials and learning environments that create a social and epistemic context and invite students to engage in the practice of visualization as evidence, reasoning, experimental procedure, or a means of communication and reflect on these practices. Implications for teacher education include the need for teacher professional development programs to problematize the use of visual representations as epistemic objects that are part of scientific practices.

STEM has become a pervasive part of global education reform. The STEM discourse positions the purpose of scientific education as being to prepare young people for work in a hyper-competitive 21st century knowledge economy, pushing aside alternative approaches focussed on interrogating social, moral and political issues in context. This narrative does not always sit comfortably with the holistic ambitions of many state and faith-based education systems. In this paper we will argue that these tensions emerge from deeper conflicts in the cultural-discursive arrangements around education in the advanced democratic states through an exploration of the response to a STEM curriculum project in a Catholic education system. The exploration is based on a phenomenographic analysis of reflective interviews conducted with participating teachers. We conclude that while the teachers are aware of the tensions, they may benefit from access to a language for discussing the various pressures on learning design and meaning making.

Background Given that limited well-developed instruments are available to assess students’ transdisciplinary STEM practices (T-STEMP), this study aims to develop and validate an instrument for examining secondary students’ T-STEMP competence. According to the T-STEMP assessment framework proposed in our previous study, we developed items and validated the items using Bayesian structural equation modeling (BSEM) and item response theory (IRT). Results First, the structure of T-STEMP has been justified, that the four design phases are related to a common third-order factor: knowledge-based reasoning and each design phase is composed of three key design challenges. The goodness of fit indices indicated that a two-parameter logistic (2PL) graded response model could fit the data well. The discrimination parameters indicated that most of the items for different grades performed well in distinguishing between students with various ability levels. The Cronbach’s alpha also indicated that the instrument had good reliability in terms of internal consistency. Conclusions The model of one third-order factor with four second-order factors and 12 first-order factors was justified as the fitted model representing the structure of the T-STEMP instrument. It means that the four design phases are related to knowledge-based reasoning and each design phase is composed of three key design challenges. The IRT findings show that Taiwanese students may have basic T-STEMP competence, but the breadth and depth of their responses to the key design challenges need to be advanced. Implications for further studies and suggestions for STEM teaching are also provided.

Background The primary objective of this paper is to provide a review of research on argumentation in science education based on publications from 1998 to 2014 in three science education journals. In recent years, the teaching and learning argumentation (i.e. the coordination of evidence and theory to support or refute an explanatory conclusion, model or prediction) has emerged as a significant educational goal. Argumentation is a critically important discourse process in science and it should be taught and learned in the science classroom as part of scientific inquiry and literacy. Argumentation stresses the evidence-based justification of knowledge claims, and it underpins reasoning across STEM domains. Our aim in this study was to investigate how argumentation has been positioned within the publications of three top academic journals: Science Education , International Journal of Science Education , and Journal of Research in Science Teaching . A methodology for content analysis of the journals is described using quantitative and qualitative techniques. Results One of the contributions of our analysis is the illustration that researchers studying argumentation from a linguistic perspective have been emphasizing related concepts in different ways. While the emphasis has been on discourse and discussion across all journals, the related concepts of talk, conversation, dialogue and negotiation were observed to a lesser extent. Likewise, the fine-level analysis of the key epistemic concepts such as reasoning, evidence and inquiry indicates variation in coverage. Conclusions The findings can provide evidence-based indicators for where more emphasis needs to be placed in future research on argumentation, and in particular they can provide guidelines for journals in soliciting articles that target underemphasized aspects of argumentation in science education.

This article examines STEM learning as a cultural process with a focus on non-dominant communities. Building on my work in funds of knowledge and mathematics education, I present three vignettes to raise some questions around connections between in-school and out-of-school mathematics. How do we define competence? How do task and environment affect engagement? What is the role of affect, language, and cognition in different settings? These vignettes serve to highlight the complexity of moving across different domains of STEM practice—everyday life, school, and STEM disciplines. Based on findings from occupational interviews I discuss characteristics of learning and engaging in everyday practices and propose several areas for further research, including the nature of everyday STEM practices, valorization of knowledge, language choice, and different forms of engagement.

The Graft Processing subcommittee of the Worldwide Network for Blood and Marrow Transplantation wrote this guideline to assist physicians and laboratory technologists with the setting up of a cell processing laboratory (CPL) to support a hematopoietic stem cell transplant program, thereby facilitating the start-up of a transplant program in a new location and improving patient access to transplantation worldwide. This guideline describes the minimal essential features of designing such a laboratory and provides a list of equipment and supply needs and staffing recommendations. It describes the typical scope of services that a CPL is expected to perform, including product testing services, and discusses the basic principles behind the most frequent procedures. Quality management (QM) principles specific to a CPL are also discussed. References to additional guidance documents that are available worldwide to assist with QM and regulatory compliance are also provided.

The shift from science inquiry to science practices as recommended in the US reports A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas and the Next Generation Science Standards has implications for classroom/school level instruction and assessment practices and, therefore, for teacher’s professional development. We explore some of these implications and the nuances of adopting a practice orientation for science education through the lens of one NGSS practice ‘Planning and Carrying Out Investigations’ (PCOI). We argue that a focus on any one practice must necessarily consider embracing a ‘suite of practices’ approach to guide in the design of the curriculum, instruction, assessment, and evaluation. We introduce the 5D model as a curriculum and instruction framework (1) to examine how unpacking PCOI can help teachers bridge to other less-familiar-to-teachers NGSS practices and (2) to help capture the ‘struggle’ of doing science by problematizing and unpacking for students the 5D component elements of measurement and observation. 1. Deciding what and how to measure, observe, and sample; 2. Developing or selecting procedures/tools to measure and collect data; 3. Documenting and systematically recording results and observations; 4. Devising representations for structuring data and patterns of observations; and 5. Determining if (1) the data are good (valid and reliable) and can be used as evidence, (2) additional or new data are needed, or (3) a new investigation design or set of measurements are needed. Our hypothesis is that the 5D model provides struggle type experiences for students to acquire not only conceptual, procedural and epistemic knowledge but also to attain desired ‘knowledge problematic’ images of the nature of science. Additionally, we further contend that PCOI is a more familiar professional development context for teachers wherein the 5D approach can help bridge the gap between the less familiar and the more complex practices such as building and refining models and explanations.

This book examines how educators internationally can better understand the role of education as a public good designed to nurture peace, tolerance, sustainable livelihoods and human fulfilment. Bringing together empirical and theoretical perspectives, this insightful text develops new understandings of education for sustainable development and global citizenship (ESD/GC) and illustrates how these might impact on educational research, policy and practice. The text recognizes the ESD/GC as pivotal to the universal ambitions of UNESCO’s Sustainable Development Goals, and focuses on the role of teachers and teacher educators in delivering the appropriate educational response to promote equity and sustainability. Chapters explore factors including curriculum design, values and assessment in teacher education, and consider how each and every learner can be guaranteed an understanding of their role in promoting a just and sustainable global society. This book will be of great interest to academics, researchers, school leaders, practitioners, policy makers and students in the fields of education, teacher education and sustainability.

Background Design and science inquiry are intertwined during engineering practice. In this study, we examined the relationship between design behaviors and scientific explanations. Data on student design processes were collected as students engaged in a project on designing energy-efficient buildings on a blank square city block surrounded by existing buildings using a computer-aided design program, Energy3D, with built-in solar energy simulation capabilities. We used criterion sampling to select two highly reflective students among 63 high school students. Results The main data sources were design replays (automatic playback of student design sequences within the CAD software) and electronic notes taken by the students. We identified evidence of informed design such as problem framing, idea fluency, and balancing benefits and trade-offs. Opportunities for meaningful science learning through engineering design occurred when students attempted to balance design benefits and trade-offs. Conclusions The results suggest that design projects used in classrooms should emphasize trade-off analysis and include time and resources for supporting trade-off decisions through experimentation and reflection. Future research should explore ways to visualize patterns of design behavior based on large samples of students.
