In this response, we attempt to clarify our position on conceptual change, state our position on mental models being a viable construct to represent learning, indicate important issues from the social cultural perspective that can inform our work on conceptual change and lastly comment on issues that we consider to be straw men. Above all we argue that there is no best theory of teaching and learning and argue for a multiple perspective approach to understanding science teaching and learning.

Bringing a greater number of students into science is one of, if not the most fundamental goals of science education for all, especially for heretofore-neglected groups of society such as women and Aboriginal students. Providing students with opportunities to experience how science really is enacted—i.e., authentic science—has been advocated as an important means to allow students to know and learn about science. The purpose of this paper is to problematize how “authentic” science experiences may mediate students’ orientations towards science and scientific career choices. Based on a larger ethnographic study, we present the case of an Aboriginal student who engaged in a scientific internship program. We draw on cultural–historical activity theory to understand the intersection between science as practice and the mundane practices in which students participate as part of their daily lives. Following Brad, we articulate our understanding of the ways in which he hybridized the various mundane and scientific practices that intersected in and through his participation and by which he realized his cultural identity as an Aboriginal. Mediated by this hybridization, we observe changes in his orientation towards science and his career choices. We use this case study to revisit methodological implications for understanding the role of “authentic science experiences” in science education.

In science education, inquiry-based approaches to teaching and learning provide a framework for students to building critical-thinking and problem-solving skills. Teacher professional development has been an ongoing focus for promoting such educational reforms. However, despite a strong consensus regarding best practices for professional development, relatively little systematic research has documented classroom changes consequent to these experiences. This paper reports on the impact of sustained, multiyear professional development in a program that combined neuroscience content and knowledge of the neurobiology of learning with inquiry-based pedagogy on teachers’ inquiry-based practices. Classroom observations demonstrated the value of multiyear professional development in solidifying adoption of inquiry-based practices and cultivating progressive yearly growth in the cognitive environment of impacted classrooms.Current discussion about educational reform among business leaders, politicians, and educators revolves around the idea students need “21st century skills” to be successful today (Rotherham and Willingham, 2009 ). Proponents argue that to be prepared for college and to be competitive in the 21st-century workplace, students need to be able to identify issues, acquire and use new information, understand complex systems, use technologies, and apply critical and creative thinking skills (US Department of Labor, 1991 ; Bybee et al., 2007 ; Conley, 2007 ). Advocates of 21st-century skills favor student-centered methods—for example, problem-based learning and project-based learning. In science education, inquiry-based approaches to teaching and learning provide one framework for students to build these critical-thinking and problem-solving skills (American Association for the Advancement of Science [AAAS], 1993 ; National Research Council [NRC], 2000 ; Capps et al., 2012 ).Unfortunately, in spite of the central role of inquiry in the national and state science standards, inquiry-based instruction is rarely implemented in secondary classrooms (Weiss et al., 1994 ; Bybee, 1997 ; Hudson et al., 2002 ; Smith et al., 2002 ; Capps et al., 2012 ). Guiding a classroom through planning, executing, analyzing, and evaluating open-ended investigations requires teachers to have sufficient expertise, content knowledge, and self-confidence to be able to maneuver through multiple potential roadblocks. Researchers cite myriad reasons for the lack of widespread inquiry-based instruction in schools: traditional beliefs about teaching and learning (Roehrig and Luft, 2004 ; Saad and BouJaoude, 2012 ), lack of pedagogical skills (Shulman, 1986 ; Adams and Krockover, 1997 ; Crawford, 2007 ), lack of time (Loughran, 1994 ), inadequate knowledge of the practice of science (Duschl, 1987 ; DeBoer, 2004 ; Saad and BouJaoude, 2012 ), perceived time constraints due to high-stakes testing, and inadequate preparation in science (Krajcik et al., 2000 ). Yet teachers are necessarily at the center of reform, as they make instructional and pedagogical decisions within their own classrooms (Cuban, 1990 ). Given that effectiveness of teachers’ classroom practices is critical to the success of current science education reforms, teacher professional development has been an ongoing focus for promoting educational reform (Corcoran, 1995 ; Corcoran et al., 1998 ).A review of the education research literature yields an extensive knowledge base in “best practices” for professional development (Corcoran, 1995 ; NRC, 1996 ; Loucks-Horsley and Matsumoto, 1999 ; Loucks-Horsley et al., 2009 ; Haslam and Fabiano, 2001 ; Wei et al., 2010 ). However, in spite of a strong consensus on what constitutes best practices for professional development (Desimone, 2009 ; Wei et al., 2010 ), relatively little systematic research has been conducted to support this consensus (Garet et al., 2001 ). Similarly, when specifically considering the science education literature, several studies have been published on the impact of teacher professional development on inquiry-based practices (e.g., Supovitz and Turner, 2000 ; Banilower et al., 2007 ; Capps et al., 2012 ). Unfortunately, these studies usually rely on teacher self-report data; few studies have reported empirical evidence of what actually occurs in the classroom following a professional development experience.Thus, in this study, we set out to determine through observational empirical data whether documented effective professional development does indeed change classroom practices. In this paper, we describe an extensive professional development experience for middle school biology teachers designed to develop teachers’ neuroscience content knowledge and inquiry-based pedagogical practices. We investigate the impact of professional development delivered collaboratively by experts in science and pedagogy on promoting inquiry-based instruction and an investigative classroom culture. The study was guided by the following research questions:
  1. Were teachers able to increase their neuroscience content knowledge?
  2. Were teachers able to effectively implement student-centered reform or inquiry-based pedagogy?
  3. Would multiple years of professional development result in greater changes in teacher practices?
Current reforms in science education require fundamental changes in how students are taught science. For most teachers, this requires rethinking their own practices and developing new roles both for themselves as teachers and for their students (Darling-Hammond and McLaughlin, 1995 ). Many teachers learned to teach using a model of teaching and learning that focuses heavily on memorizing facts (Porter and Brophy, 1988 ; Cohen et al., 1993 ; Darling-Hammond and McLaughlin, 1995 ), and this traditional and didactic model of instruction still dominates instruction in U.S. classrooms. A recent national observation study found that only 14% of science lessons were of high quality, providing students an opportunity to learn important science concepts (Banilower et al., 2006 ). Shifting to an inquiry-based approach to teaching places more emphasis on conceptual understanding of subject matter, as well as an emphasis on the process of establishing and validating scientific concepts and claims (Anderson, 1989 ; Borko and Putnam, 1996 ). In effect, professional development must provide opportunities for teachers to reflect critically on their practices and to fashion new knowledge and beliefs about content, pedagogy, and learners (Darling-Hammond and McLaughlin, 1995 ; Wei et al., 2010 ). If teachers are uncomfortable with a subject or believe they cannot teach science, they may focus less time on it and impart negative feelings about the subject to their students. In this way, content knowledge influences teachers’ beliefs about teaching and personal self-efficacy (Gresham, 2008 ). Personal self-efficacy was first defined as “the conviction that one can successfully execute the behavior required to produce the outcomes” (Bandura, 1977 , p.193). Researchers have reported self-efficacy to be strongly correlated with teachers’ ability to implement reform-based practices (Mesquita and Drake, 1994 ; Marshall et al., 2009 ).Inquiry is “a multifaceted activity that involves making observations, posing questions, examining books and other sources of information, planning investigations, reviewing what is already known in light of evidence, using tools to gather, analyze and interpret data, proposing answers, explanations and predictions, and communicating the results” (NRC, 1996 , p. 23). Unfortunately, most preservice teachers rarely experience inquiry-based instruction in their undergraduate science courses. Instead, they listen to lectures on science and participate in laboratory exercises with guidelines for finding the expected answer (Gess-Newsome and Lederman, 1993 ; DeHaan, 2005 ). As such, teachers’ knowledge and beliefs about teaching and learning were developed over the many years of their own educations, through “apprenticeship of observation” (Lortie, 1975 ), in traditional lecture-based settings that they then replicate in their own classrooms. To support the implementation of inquiry in K–12 classrooms, teachers need firsthand experiences of inquiry, questioning, and experimentation within professional development programs (Gess-Newsome, 1999 ; Supovitz and Turner, 2000 ; Capps et al., 2012 ).A common criticism of professional development activities is that they are too often one-shot workshops with limited follow-up after the workshop activities (Darling-Hammond, 2005 ; Wei et al., 2010 ). The literature on teacher learning and professional development calls for professional development that is sustained over time, as the duration of professional development is related to the depth of teacher change (Shields et al., 1998 ; Weiss et al., 1998 ; Supovitz and Turner, 2000 ; Banilower et al., 2007 ). If the professional development program is too short in duration, teachers may dismiss the suggested practices or at best assimilate teaching strategies into their current repertoire with little substantive change (Tyack and Cuban, 1995 ; Coburn, 2004 ). For example, Supovitz and Turner (2000 ) found that sustained professional development (more than 80 h) was needed to create an investigative classroom culture in science, as opposed to small-scale changes in practices. Teachers need professional development that is interactive with their teaching practices; in other words, professional development programs should allow time for teachers to try out new practices, to obtain feedback on their teaching, and to reflect on these new practices. Not only is duration (total number of hours) of professional development important, but also the time span of the professional development experience (number of years across which professional hours are situated) to allow for multiple cycles of presentation and reflection on practices (Blumenfeld et al., 1991 ; Garet et al., 2001 ). Supovitz and Turner''s study (2000) suggests that it is more difficult to change classroom culture than teaching practices; the greatest changes in teaching practices occurred after 80 h of professional development, while changes in classroom investigative culture did not occur until after 160 h of professional development.Finally, research indicates that professional development that focuses on science content and how children learn is important in changing teaching practices (e.g., Corcoran, 1995 ; Desimone, 2009 ), particularly when the goal is the implementation of inquiry-like instruction designed to improve students’ conceptual understanding (Fennema et al., 1996 ; Cohen and Hill, 1998 ). The science content chosen for the professional development series described in this study was neuroscience. This content is relevant for both middle and high school science teachers and has direct connections to standards. It also is unique in that it encompasses material on the neurological basis for learning, thus allowing discussions about student learning to occur within both a scientific and pedagogical context. As a final note, it is rare for even a life science teacher to have taken any coursework in neuroscience. The inquiry-based lessons and experiments encountered by the teachers during the professional development provide an authentic learning experience, allowing teachers to truly inhabit the role of a learner in an inquiry-based setting.  相似文献

Members of particular communities produce and reproduce cultural practices. This is an important consideration for those teacher educators who need to prepare appropriate learning experiences and programs for scientists, as they attempt to change careers to science teaching. We know little about the transition of career-changing scientists as they encounter different contexts and professional cultures, and how their changing identities might impact on their teaching practices. In this narrative inquiry of the stories told by and shared between career-changing scientists in a teacher-preparation program, we identify cover stories of science and teaching. More importantly, we show how uncovering these stories became opportunities for one of these scientists to learn about what sorts of stories of science she tells or should tell in science classrooms and how these stories might impact on her identities as a scientist–teacher in transition. We highlight self-identified contradictions and treat these as resources for further professional learning. Suggestions for improving the teacher-education experiences of scientist–teachers are made. In particular, teacher educators might consider the merits of creating opportunities for career-changing scientists to share their stories and for these stories to be retold for different audiences.

In much of the educational literature, researchers make little distinction between African-American students and students of the African Diaspora who immigrated to the United States. Failing to describe these salient student differences serves to perpetuate an inaccurate view of African-American school life. In today’s large cities, students of the African Diaspora are frequently learning science in settings that are devoid of the resources and tools to fully support their success. While much of the scholarship unites these disparate groups, this article details the distinctive learning culture created when students from several groups of the African Diaspora learn biology together in a Brooklyn Suspension Center. Specifically this work explains how one student, Gabriel, functions in a biology class. A self-described black-Panamanian, Gabriel had tacitly resigned to not learning science, which then, in effect, precluded him from any further associated courses of study in science, and may have excluded him from the possibility of a science related career. This ethnography follows Gabriel’s science learning as he engaged in cogenerative dialogue with teachers to create aligned learning and teaching practices. During the 5 months of this research, Gabriel drew upon his unique lifeworld and the depth of his hybridized cultural identity to produce limited, but nonetheless important demonstrations of science. Coexistent with his involvement in cogenerative dialogue, Gabriel helped to construct many classroom practices that supported a dynamic learning environment which produced small yet concrete examples of standards based biology. This study supports further investigation by the science education community to consider ways that students’ lifeworld experiences can serve to structure and transform the urban science classroom.

Introducing critical pedagogies into undergraduate early childhood teacher education programs may enable working class teachers who work with working class children to better examine assumptions of developmentally and culturally appropriate practices. This study focuses on a Latino assistant teacher who, after having returned from a semester of student teaching, attempted to cultivate an ethos of professional interaction among his peers. His ability to name, challenge and ultimately reject inappropriate ideologies and practices (Bartolomé, 2004 Bartolomé, L. I. 2004. Critical pedagogy and teacher education: Radicalizing perspective teachers. Teacher Education Quarterly, 31(1): 97–122.  [Google Scholar]) are coupled with his concern for his children and his community. Illustrating Dahlberg, Moss, and Pence's definitions of “quality” and “meaning making,” (2001) this study also considers ways in which administrators and teacher educators can respond to and support teachers who return to their jobs after their student-teaching experiences.  相似文献

This article relates how an English teacher in an urban high school described his efforts to listen and to perceive a seemingly disaffected student in his efforts to support her learning. He observed her responding to his efforts in positive and unexpected ways that involved her increased involvement in learning in his class. This teacher described how this student had presented many challenges to his teaching and how difficult attending to her overt anger and sullenness in his class was for him. However, by doing so, he said that his perceptions and understandings of her and subsequently, another student, shifted profoundly in ways that he believed helped him help these two students learn more meaningfully in his classes. This example of open listening on the part of a teacher toward his two students opened up new possibilities for learning for all three and may indicate a cycle of transformative listening which will be defined and discussed in this article. Stuart’s experiences in a professional development seminar, facilitated by the author, where teachers’ interpretive and evaluative ideas were listened to openly by colleagues and the facilitator may have influenced Stuart in his responses to his students. His involvement in this study group may have contributed to his learning to see his students in new, unique, and fuller ways, which he said he thought helped him help these students learn better in his classes.

We discuss the eight papers in this issue of Cultural Studies of Science Education focusing on the debate over conceptual change in science education and explore the issues that have emerged for us as we consider how conceptual change research relates to our practice as science educators. In presenting our interpretations of this research, we consider the role of participants in the research process and contextual factors in conducting research on science conceptions, and draw implications for the teaching of science.

Her research interests focus on pre-service and in-service preparation for the teaching of science and she is currently researching the use of coteaching and cogenerative dialogue in elementary teacher preparation for the teaching of science. In particular, she is exploring the role that shared, supported teaching experiences can have in the construction of new teacher identity and solidarity. She has worked as an elementary science specialist teaching children in grades K-5, and in museum settings developing science programs for teachers and children. In addition to the position at Manhattanville College, Chris is a lecturer in the University of Pennsylvania’s Science Teacher Institute where she teaches science pedagogy to middle school teachers. Gail Horowitz   is an instructor of chemistry at Yeshiva University, and a doctoral candidate in science education at Teachers College. For many years, she has been involved in research and curricular design within the organic chemistry laboratory setting, focusing specifically on the design of discovery or puzzle based experiments. Her doctoral research focuses on the intrinsic motivation of pre-med students. She is interested in trying to characterize and describe the academic goal orientations of pre-med students, and is interested in exploring how the curricular elements embedded in project based laboratory curricula may or may not serve to enhance their intrinsic motivation. Femi S. Otulaja   is currently a PhD student and an adjunct professor of science teacher education at Queens College of the City University of New York. As a science teacher educator, his research interests focus on the use of cogenerative dialoguing and its residuals, such as coteaching, distributed leadership, culturally responsive pedagogy, as research and pedagogical tools for engaging, training and apprenticing urban middle and high schools pre- and in-service science teachers as legitimate peripheral participants. He also encourages the use of these modalities as assessment, evaluation and professional development tools for teaching and learning science and for realigning cultural misalignments in urban classrooms. His theoretical framework consists of a bricolage of participatory action research, constructivism, critical ethnography, cultural sociology, sociology of emotions, indigenous epistemology, culturally responsive pedagogy, critical pedagogy and conversation analyses. In addition, he advocates the use of technologies as assistive tools in teaching science. Nicole Gillespie   is a Senior Program Officer at the Knowles Science Teaching Foundation (KSTF). She is a former naval officer and high school physics teacher. Nicole received her PhD in science education from the University of California, Berkeley in 2004 where she was supported by a Spencer Dissertation Fellowship. She worked with the Physics Education Group at the University of Washington and conducted research on students’ intuitive ideas about force and model-based reasoning and argumentation among undergraduate physics students at Berkeley. In addition to her work at KSTF, Nicole is an instructor in the University of Pennsylvania’s Science Teacher Institute. Ashraf Shady   is a PhD candidate in the Urban Education program at the City University of New York Graduate Center; his strand of concentration is science, math, and technology. In his research he is currently using theoretical frameworks from cultural sociology and the sociology of emotion to examine how learning and teaching of science are enacted when students and their teachers are able to co-participate in culturally adaptive ways and use their social and symbolic capital successfully. His research interests focus on the use of cogenerative dialogues as a methodology to navigate cultural fields in urban education. Central to his philosophy as a science educator is the notion that teaching is a form of cultural enactment. As such, teaching, and learning are regarded as cultural production, reproduction, and transformation. This triple dialectic affirms that elements of culture are associated with the sociocultural backgrounds of participating stakeholders. Line A. Augustin   received her doctorate degree in Chemistry (with a chapter of her dissertation on a case study of enactment of chemical knowledge of a high school student) and did a post-doc on Science Education at the Graduate Center, CUNY. She is currently teaching science content and methods courses in the Elementary and Early Childhood Education Department of Queens College, CUNY. She is interesting in investigating how racial, cultural, class and gender issues affect the ways that teaching and learning occurs in elementary classrooms, in understanding these issues and developing mechanism by which they can be utilized to promote better teaching and learning environment and greater dispositions towards science. She is also interested in what influences science teachers to change and/or to improve their teaching practices.  相似文献

In this study, I used a feminist poststructural perspective to explain how language is a gatekeeper in learning science, in achieving professional honors in teaching science, and in teaching science to English language learners. The various uses of language revealed interesting dynamics related to the culture of power of language and the culture of power of science along race–ethnicity, gender, and class dimensions for teachers. Teachers did not necessarily see language as having distinct purposes and uses. This further maintained the gatekeeping nature of language and discourse in science education. I discuss implications for looking at language in science education for teacher professional development and student learning.

The article documents the complex process of changing Argentina’s science curriculum and implementing those changes over the last 15 years. It recounts how reformers tackled the challenges of balancing national (federal) unity in education with local (provincial) autonomy from the political, social and pedagogical points of view. It also analyzes various attempts to improve science education in Argentina from the viewpoint of their relevance to current developments in various areas of scientific knowledge and human action. In Argentina the effort to ensure equal opportunities for learners at the federal level led to a strong emphasis on developing Common Basic Contents (CBC) for both primary and secondary education. These contents were seen as fundamental components of the competencies that students need in a world increasingly driven by science and technology. Meanwhile, however, Argentina lacked adequate and sustainable policies and strategies for teacher education and training, which led to an unexpected complication: while the curriculum development process led to diverse and sometimes quite sophisticated curriculum documents, the actual quality of science teaching in the classroom did not improve significantly, and teachers still felt the need for more support before they could effectively implement the new science curriculum. The article ends by suggesting ways in which various stakeholders can work together intensively to improve science education in Argentina, in a new process that will respond to the current situation.

Lesson study is highly regarded as a model for professional learning, yet remains under-theorised. This article examines the professional learning experiences of teachers and numeracy coaches from three schools in a local network of schools, participating in a lesson study project over two research cycles in 2012. It maps the interconnections between their experiences and their beliefs and practices, using Clarke and Hollingsworth’s (Teach Educ 18(8):947–967, 2002) Interconnected Model of Professional Growth. Analysis of interview data and video-recordings of planning meetings, research lessons, and post-lesson discussions reveals the development of teachers’ collaborative planning skills, increased attention to students’ mathematical thinking, use of orchestrated whole-class discussion based on anticipated student solutions and focused questioning, and the enhancement of collaborative practices for teacher inquiry. Our findings illuminate the interplay between the External Domain, the Personal Domain, the Domain of Practice, and the Domain of Consequence, in the teaching and learning change environment, and the mediating processes of enactment and reflection. Changes in the domains across the period of the lesson study provide evidence of teachers’ professional growth, with the iterative processes of enactment and reflection being critical in mediating this professional growth.  相似文献

Current reform in science education calls for teachers to understand student thinking within a lesson to effectively address students’ needs (NRC in A framework for K-12 science education: practices, crosscutting concepts, and core ideas. National Academy Press, Washington, DC, 2012; NRC in Guide to implementing the Next Generation Science Standards. The National Academies Press, Washington, DC, 2015). This study investigates how to scaffold preservice teachers with learning to attend to students’ thinking for the purpose of guiding curricular decisions. The study focuses on one team teaching a science unit during their early field experience. We sought to understand how participants’ thoughts and abilities changed through participation in a moderated community of practice using video of their own teaching as a reflective tool. We examined how these changes affected both their classroom practice and their decision-making for future lessons. Evidence shows growth in participants’ ability to identify opportunities to elicit, assess, and use students’ thinking to guide instructional decisions. Implications for use of the approach used in this study to begin developing novice teachers’ pedagogical content knowledge for teaching science are discussed.  相似文献

Allchin (2006) has misinterpreted a classic case of hypothetico-deductive (HD) science in terms of his preferred ‘let’s-gather-some-data-and-see-what-emerges’ view. The misrepresentation concerns the research program of Peter and Rosemary Grant on Darwin’s finches. The present essay argues that the Grants’ research is HD in nature and includes a statement by Peter Grant to that effect.

Dr. Anton E. Lawson’s   career in science education began in the late 1960s in California where he taught middle school science and mathematics for 3 years before completing his PhD at the University of Oklahoma and moving to Purdue University in 1973. Lawson continued his research career at the University of California Berkeley in 1974, and then moved to Arizona State University in 1977, where he currently conducts research and teaches courses in biology, in biology teaching methods, and in research methods. Lawson has directed over 100 workshops for teachers, mostly on inquiry teaching methods, and has published over 200 articles and over 20 books including Science Teaching and the Development of Thinking (Wadsworth: Belmont, CA, 1995), Biology: A Critical Thinking Approach, (Addison Wesley: Menlo Park, CA, 1994), and The Neurological Basis of Learning, Development and Discovery (Kluwer: Dordrecht, The Netherlands, 2003). Lawson’s most recent book is an introductory biology text called Biology: An Inquiry Approach (Kendall/Hunt: Dubuque, IA, 2004). Lawson is perhaps best known for his research articles in science education, which have three times been judged to be the most significant articles of the year by the National Association for Research in Science Teaching (NARST). He has also received NARST’s career award for distinguished contributions to Science Education Research as well as the outstanding science educator of the year award by the Association for the Education of Teachers in Science.  相似文献

The Durkheimian concept of the density of social relationships may prove more fruitful than the historical materialist notion of a social hierarchy for thinking about the social location of epistemic agents in science. To define a scientist’s social location in terms of the density of her professional relationships with other scientists permits us to give a more precise characterization of marginalization and thus to formulate more testable hypotheses about marginalized groups in science. The notion of social density helps to explain not only how some individual scientists are more likely than others to get a hearing for their ideas, but also how scientific inquiry flourishes more in some societies than in others.

Black males, as one non-dominant population, remain underrepresented and less successful in science, technology, engineering, and mathematics (STEM). Researchers focused on non-dominant populations are advised against generalizations and to examine cultural intersections (i.e. race, ethnicity, gender, and more) and also to explore cases of success, in addition to cases of under-achievement and underrepresentation. This study has focused on one African American male, Randy, who expressed high-achieving STEM career goals in computer science and engineering. Furthermore, recognizing that culture and identity development underlie STEM engagement and persistence, this long-term case study focused on how Randy developed a STEM identity during the course of the study and the implications of that process for his STEM career exploration. Étienne Wenger’s (1999) communities-of-practice (CoP) was employed as a theoretical framework and, in doing so, (1) the informal STEM program in which Randy participated was characterized as a STEM-for-social-justice CoP and (2) Randy participated in ways that consistently utilized an “economics” lens from beyond the boundaries of the CoP. In doing so, Randy functioned as a broker within the CoP and developed a non-traditional STEM identity-in-practice which integrated STEM, “economics”, and community engagement. Randy’s STEM identity-in-practice is discussed in terms of the contextual factors that support scientific identity development (Hazari et al. in J Res Sci Teach 47:978–1003, 2010), the importance of recognizing and supporting the development of holistic and non-traditional STEM identities, especially for diverse populations in STEM, and the implications of this new understanding of Randy’s STEM identity for his long-term STEM career exploration.  相似文献

This paper reports on a teacher’s and his students’ responsiveness to a new tetrahedral-oriented (Mahaffy in J Chem Educ 83(1):49–55, 2006) curriculum requiring more discursive classroom practices in the teaching of chemistry. In this instrumental case study, we identify the intentions of this learner-centered curriculum and a teacher’s development in response to this curriculum. We also explore the tensions this teacher experiences as students subsequently respond to his adjusted teaching. We use a Chemistry Teacher Inventory (Lewthwaite and Wiebe in Res Sci Educ 40(11):667-689, 2011; Lewthwaite and Wiebe in Can J Math Sci Technol Educ 12(1):36–61, 2012; Lewthwaite in Chem Educ Res Pract. doi:10.1039/C3RP00122A, 2014) to assist the teacher in monitoring how he teaches and how he would like to improve his teaching. We also use a student form of the instrument, the Chemistry Classroom Inventory and Classroom Observation Protocol (Lewthwaite and Wiebe 2011) to verify the teacher’s teaching and perception of student preferences for his teaching especially in terms of the discursive processes the curriculum encourages. By so doing, the teacher is able to use both sets of data as a foundation for critical reflection and work towards resolution of the incongruence in data arising from students’ preferred learning orientations and his teaching aspirations. Implications of this study in regards to the authority of students’ voice in triggering teachers’ pedagogical change and the adjustments in ‘teachering’ and ‘studenting’ required by such curricula are considered.  相似文献

With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers’ ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council’s A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants’ written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers’ content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.  相似文献
