Preservice science teachers face numerous challenges in understanding and teaching science as inquiry. Over the course of their teacher education program, they are expected to move from veteran science students with little experience learning their discipline through inquiry instruction to beginning science teachers adept at implementing inquiry in their own classrooms. In this study, we used Aikenhead’s (Sci Educ 81: 217–238, 1997, Science Educ 85:180–188, 2001) notion of border crossing to describe this transition preservice teachers must make from science student to science teacher. We examined what one cohort of eight preservice secondary science teachers said, did, and wrote as they both conducted a two-part inquiry investigation and designed an inquiry lesson plan. We conducted two types of qualitative analyses. One, we drew from Costa (Sci Educ 79: 313–333, 1995) to group our preservice teacher participants into one of four types of potential science teachers. Two, we identified successes and struggles in preservice teachers’ attempts to negotiate the cultural border between veteran student and beginning teacher. In our implications, we argue that preservice teachers could benefit from explicit opportunities to navigate the border between learning and teaching science; such opportunities could deepen their conceptions of inquiry beyond those exclusively fashioned as either student or teacher.  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

Societal benefit depends on the general public’s understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439–443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57–69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93–99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110–134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175–218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916–937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as “authentic” if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110–134, 2009; Chinn and Malhotra in Sci Educ 86(2):175–218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced their understanding of biotechnology? As respondents explored numerous ideas in order to develop a workable research question, struggled to create a viable protocol, executed their experiment, and then evaluated their results, they commented on unexpected topics regarding the nature of science as well as specific content knowledge relating to their experiments. Four out of five participants reported they learned the most during authentic inquiry laboratory experience.  相似文献

The need to reform science teacher preparation programs has been pointed out in research (Bryan and Abell in J Res Sci Teach 36:121–140, 1999; Bryan and Atwater in Sci Educ 8(6):821–839, 2002; Harrington and Hathaway in J Teach Educ 46(4):275–284, 1995). Science teachers are charged with the responsibility of incorporating both cognitive and non-cognitive parameters in their everyday teaching practices. This often results in their reluctance to teach science because they often lack disciplinary and/or pedagogical expertise required to promote science learning. The purpose of this study is to propose an alternative instructional approach in which Lego vehicles were used as a tool to promote pre-service elementary teachers’ development and to examine whether there are non-cognitive parameters that promote or obstruct them from using Lego Technologies as a teaching tool. The context of the study was defined by a teacher preparation program of a private university in a small Mediterranean country. A sample of 28 pre-service elementary teachers, working in five 5–6-member groups were involved in scientific inquiries, during which they had to use vehicles in order to solve scientific problems related to concepts such as gear functioning, force, and motion. The nature of their cognitive engagement in the scientific inquiry process, non-cognitive parameters contributing to their cognitive engagement, and the impact of their involvement in the process on their development were examined through qualitative analysis of pre- and post-inquiry interviews, presentations of their solutions to the scientific problems and of their personal reflective journals.  相似文献

This study explored the nature of the relationship between a fifth-grade teacher and an informal science educator as they planned and implemented a life science unit in the classroom, and sought to define this relationship in order to gain insight into the roles of each educator. In addition, student learning as a result of instruction was assessed. Prior research has predominately examined relationships and roles of groups of teachers and informal educators in the museum setting (Tal et al. in Sci Educ 89:920–935, 2005; Tal and Steiner in Can J Sci Math Technol Educ 6:25–46, 2006; Tran 2007). The current study utilized case study methodology to examine one relationship (between two educators) in more depth and in a different setting—an elementary classroom. The relationship was defined through a framework of cooperation, coordination, and collaboration (Buck 1998; Intriligator 1986, 1992) containing eight dimensions. Findings suggest a relationship of coordination, which requires moderate commitment, risk, negotiation, and involvement, and examined the roles that each educator played and how they negotiated these roles. Consistent with previous examinations in science education of educator roles, the informal educator’s role was to provide the students with expertise and resources not readily available to them. The roles played by the classroom teacher included classroom management, making connections to classroom activities and curricula, and clarifying concepts. Both educators’ perceptions suggested they were at ease with their roles and that they felt these roles were critical to the optimization of the short time frames (1 h) the informal educator was in the classroom. Pre and posttest tests demonstrated students learned as a result of the programs.  相似文献

While some researchers have argued for science classrooms that embrace open-inquiry by engaging students in doing science as scientists do (cf. National Research Council [NRC] 1996; Driver et al. in Sci Educ 84:287–312, 2000; Windschitl et al. in Sci Educ 87(1):112–143, 2008), others have argued that open-inquiry is impractical, ineffective, and perhaps even counter-productive towards promoting normative scientific ideas (cf. Kirschner et al. in Educ Psychol 41(2):75–86, 2006; Settlage in J Sci Teach Educ 18:461–467, 2007). One of the challenges in informing the debate on this issue is the scarcity of well-documented courses that engage students in open-inquiry characteristic of scientific research. This paper describes the design, implementation, and outcomes of such a course for undergraduates planning on becoming elementary teachers. The goal of the class was to immerse future teachers in authentic, open-inquiry (without specific learning goals related to scientific concepts) in hopes that students would come away with a deeper understanding of the nature of science (NOS) and improved attitudes towards science. Data collected from a variety of sources indicate that an authentic, open-inquiry experience is feasible to implement in an undergraduate setting, gives students a more sophisticated NOS understanding, improves students’ attitudes towards science and open-inquiry, and changes the way they intend to teach science in their future classrooms.  相似文献

Professional development becomes relevant and effective when teachers are actively involved, collaborate, and when it is linked to teachers’ daily school practice (Hunzicker in Prof Dev Educ 37:177–179, 2011). Preparation of teachers for a curriculum implementation such as the new subject Nature, Life, and Technology can be done by a professional development programme where teachers are actively involved (Visser et al. 2010). This study evaluates the designed and implemented professional development programme with respect to its effectiveness in terms of degree of teacher learning and development. Effects are evaluated for five learning areas: Instructional strategies, differences in students’ prior knowledge, adjustments to the module, assessment methods and instruments, and field trips and guest lectures. Eleven teachers from four different schools participated in two professional development programmes, six teachers in the first professional development programme and five teachers in the programme for the subsequent module. Questionnaires and interviews were used to assess the effects in the different learning areas. The findings show that the professional development programme is a useful venture for teachers’ professional growth in different learning areas.  相似文献

This article reports on a national survey of higher education institutions in the United States to answer the question, “Who teaches mathematics content courses for prospective elementary teachers, and what are these instructors’ academic and teaching backgrounds?” We surveyed 1,926 institutions, and a faculty member from each of 825 institutions (42.8?%) participated in the survey. The survey results demonstrate that the majority of institutions are not meeting the recommendations of the Conference Board of the Mathematical Sciences (The mathematical education of teachers. American Mathematical Society, Providence, RI, 2001), the National Council of Teachers of Mathematics (Professional standards for teaching mathematics. National Council of Teachers of Mathematics, Reston, VA, 2005), and the National Council on Teacher Quality (Greenberg and Walsh 2008) for prospective elementary teachers to take at least nine credits of mathematics content designed specifically for them. Additionally, most instructors for these courses do not have elementary teaching experience and have likely not had opportunities to think deeply about the important ideas in elementary mathematics, and most institutions do not provide training and/or support for these instructors.  相似文献

Modern education is often characterized by a tension between learning and creativity (Connery et al. in Vygotsky and creativity: A cultural-historical approach to play, meaning making, and the arts, 2010). ??The Arts????if attended to at all??is often positioned as a distinct element of the broader curriculum, and separate from teaching and learning within other curricular domains. Yet, despite being largely neglected within contemporary social constructivist literature, Vygotsky??s sociocultural theory of mind (Vygotsky in Mind in society, 1978; Vygotsky in The collected works of L. S. Vygotsky (Vol. 1: Problems of general psychology, 1987)) has as its core a fundamental concern for creativity, affect, and emotion as the basis for human development. This paper argues that Vygotsky??s understanding of catharsis??in particular, the transformative potential of emotion??gives cause to rethink the qualitative nature of pedagogy, and especially the importance of ??mundane creativity?? (Holzman in Vygotsky and creativity: A cultural-historical approach to play, meaning making, and the arts, 2010, p. 27) at the core of teaching and learning. This, in turn, opens up new possibilities for conceiving of how creativity might be understood and realized within and across different dimensions of the curriculum more broadly. For an empirical example to explore these constructs, the paper considers data from a ??content and language integrated learning?? (CLIL) context. Emerging in the mid-1990s as a European response to the success of the Canadian French immersion method for teaching languages (Johnson and Swain in Immersion education: International perspectives, 1997), CLIL sets out several guiding principles for integrating second language (L2) with content to develop both simultaneously. With a focus on how Japanese mediates a unit of work on Geography, the study highlights how the integrated language/content focus affords a space for creative pedagogical engagement in terms of learners making their own creative choices on what language to use, and how it could be used, to facilitate the learning of both language and content (Bachman and Palmer in Language assessment in practice: Developing language assessments and justifying their use in the real world, 2010; Mahn and John-Steiner in The gift of confidence: A Vygotskian view of emotions, 2002).  相似文献

In a recent publication, Senge (All systems go: the change imperative for whole system reform. Corwin Press, Thousand Oaks, 2010, x) stated ??at no time in history has there been a more powerful need for a new vision of the purpose of education.?? Increasingly citizens, academics and practitioners are calling for radical changes to educational practices to meet the needs of a knowledge-based society in the twenty-first century (Dede in 21st Century skills: rethinking how students learn. Solution Tree Press, Bloomington, 2010; Hargreaves and Shirley in The fourth way: the inspiring future for educational change. Corwin Press, Thousand Oaks, 2009). Accomplishing such substantive educational change requires that individual educators collectively reshape their personal professional knowledge (Connelly and Clandinin in Teachers as curriculum planners: narratives of experiences. OISE Press, Toronto, 1988; Elbaz in Curriculum Inq 11(1):43?C71, 1981) and adapt their personal mental models (Duffy in J Staff Dev 24(1):30?C36, 2003). In 2000, we began a longitudinal study on the role of a school district in facilitating significant educational reform which required adaptations to individual and collective mental models of professional practice. Annually we conducted intensive interviews with a large sample of teachers, school and system administrators in this large Ontario, Canada school district. Recently, we conducted a retrospective analysis of these data collected in order to identify the conditions necessary for a large organization to support knowledge-creation and dissemination. In this paper, we identify three school district actions that triggered individual educators to challenge and reconstruct their professional personal practical mental models of the teaching and learning. First, improved student learning became the central focus of the school district. Second, the school district stressed and created opportunities for educators to collectively engage in professional dialogue about their practice. Third, the school district emphasized the importance of educators individually and collectively using evidence to assess whether their actions improved student learning.  相似文献

This study explored the biography-driven approach to teaching culturally and linguistically diverse students in science education. Biography-driven instruction (BDI) embraces student diversity by incorporating students’ sociocultural, linguistic, cognitive, and academic dimensions of their biographies into the learning process (Herrera in Biography-driven culturally responsive teaching. Teachers College Press, New York, 2010). Strategies have been developed (Herrera, Kavimandan and Holmes in Crossing the vocabulary bridge: differentiated strategies for diverse secondary classrooms. Teachers College Press, New York, 2011) that provide teachers with instructional routines that facilitate BDI. Using systematic classroom observations we empirically demonstrate that these activate, connect, affirm, strategies are likely to be effective in increasing teachers’ biography-driven practices. Implications for theory and practice are discussed.  相似文献

How do practicing mathematics teachers continue to develop the knowledge and habits of mind that enable them to teach well and to improve their teaching over time? The question of how (and what) teachers learn lies at the crux of any effort to provide high-quality mathematics teaching for all students. This article reviews 106 articles written between 1985 and 2008 related to the professional learning of practicing teachers of mathematics. We offer a synthesis of this research, guided by Clarke and Hollingsworth’s (Teach Teach Educ 18(8):947–967, 2002) dynamic model of teacher growth. Their model emphasizes the recursive nature of teachers’ learning and suggests that growth in one aspect of teachers’ knowledge and practice may promote subsequent growth in other areas. We report the results in six major areas of teacher learning, identify several crosscutting themes in the literature, and make recommendations for future research aimed at understanding teachers’ professional learning.  相似文献

Agnotology is a term that has been used to describe the study of ignorance and its cultural production (Proctor in Agnotology: the making and unmaking of ignorance. Stanford University Press, Stanford, 2008). For issues that are contentious in the societal realm, though largely not in the scientific realm, such as human evolution or the broad basics of human-induced climate change, it has been suggested that explicit study of relevant misinformation might be a useful teaching approach (Bedford in J Geogr 109(4):159–165, 2010). Recently, Legates et al. (Sci Educ. doi:10.1007/s11191-013-9588-3, 2013) published an aggressive critique of Bedford’s (J Geogr 109(4):159–165, 2010) proposals. However, the critique is based on a comprehensive misinterpretation of Bedford’s (J Geogr 109(4):159–165, 2010) paper. Consequently, Legates et al. (Sci Educ. doi:10.1007/s11191-013-9588-3, 2013) address arguments not actually made by Bedford (J Geogr 109(4):159–165, 2010). This article is a response to Legates et al. (Sci Educ. doi:10.1007/s11191-013-9588-3, 2013), and demonstrates their errors of interpretation of Bedford (J Geogr 109(4):159–165, 2010) in several key areas: the scientific consensus on climate change; misinformation and the public perception of the scientific consensus on climate change; and agnotology as a teaching tool. We conclude by arguing that, although no single peer-reviewed publication on climate change, or any other scientific issue, should be accepted without due scrutiny, the existence of a scientific consensus—especially one as overwhelming as exists for human-induced climate change—raises the level of confidence that the overall findings of that consensus are correct.  相似文献

Although there is a great deal of theoretical and practical scholarship related to immigrant students, the extant literature most often conflates the needs of English language learners with the needs of immigrant students (Goodwin in Educ Urb Soc 34(2):156–172, 2002; Sox in Theory Pract 48:312–318, 2009; Yoon in Am Educ Res J 49(5):971–1002, 2012). Findings from this study indicate that teachers in an area with a rapidly rising immigrant population perceived immigrant students to face four significant challenges beyond linguistic considerations. By analyzing interview and focus group data from six high school Civics teachers, this qualitative collective case study is positioned to make recommendations for teachers and teacher educators by bringing attention to the challenges facing immigrant students beyond the linguistic domain in a new gateway state.  相似文献

This study investigated mathematics teachers' professional knowledge among elementary school teachers exposed to a professional training program that either supported self-regulated learning (SRL) or offered no SRL support (no-SRL). The SRL support was based on the IMPROVE metacognitive self-questioning method that directs students' attention to understanding when, why, and how to solve problems (Kramarski and Mevarech, Am Educ Res J 40:281–310, 2003). Sixty-four Israeli elementary teachers participated in a month-long professional development program to enhance mathematical and pedagogical knowledge. The course was part of a 3-year professional development program sponsored by the Israeli Ministry of Education. This mixed-method study included quantitative assessments of teachers' professional knowledge in mathematical problem solving for an authentic task based on Program for International Student Assessment's framework (Program for International Student Assessment, 2003) and in lesson planning, as well as qualitative interviews and videotaped observations of two teachers. Results indicated that teachers in the SRL program outperformed those in the no-SRL program on various problem solving skills (e.g., reflection and conceptual mathematical explanations) and lesson planning (e.g., task demands and teaching approach). Videotaped observations of actual teaching indicated that the SRL-trained teacher demonstrated more teaching practices that aimed to promote students' understanding and better supported students' regulation of their own learning, compared to the no-SRL-trained teacher. We discuss educational and practical implications.  相似文献

In the broadest sense, the goal for primary science teacher education could be described as preparing these teachers to teach for scientific literacy. Our starting point is that making such science teaching accessible and desirable for future primary science teachers is dependent not only on their science knowledge and self-confidence, but also on a whole range of interrelated sociocultural factors. This paper aims to explore how intersections between different Discourses about primary teaching and about science teaching are evidenced in primary school student teachers’ talk about becoming teachers. The study is founded in a conceptualisation of learning as a process of social participation. The conceptual framework is crafted around two key concepts: Discourse (Gee 2005) and identity (Paechter, Women’s Studies International Forum, 26(1):69–77, 2007). Empirically, the paper utilises semi-structured interviews with 11 primary student teachers enrolled in a 1-year Postgraduate Certificate of Education course. The analysis draws on five previously identified teacher Discourses: ‘Teaching science through inquiry’, ‘Traditional science teacher’, ‘Traditional primary teacher’, ‘Teacher as classroom authority’, and ‘Primary teacher as a role model’ (Danielsson and Warwick, International Journal of Science Education, 2013). It explores how the student teachers, at an early stage in their course, are starting to intersect these Discourses to negotiate their emerging identities as primary science teachers.  相似文献

In this article, I address how teachers in urban and suburban U.S. schools with multicultural and multilingual student populations demonstrate leadership both within their classrooms and schools as well as outside of them. Based on research with U.S. public school teachers in two projects (Nieto What keeps teachers going? New York: Teachers College Press 2003, Why we teach. New York: Teachers College Press 2005), various roles that teachers have in initiating, putting into practice, and sustaining change in schools are described. Implications for policymakers and administrators are then briefly explored.  相似文献

Recent research efforts (Schmidt et al. in The preparation gap: teacher education for middle school mathematics in six countries, MSU Center for Research in Mathematics and Science Education, 2007) demonstrate that teacher development programs in high-performing countries offer experiences that are designed to develop both mathematical knowledge and pedagogical knowledge. However, identifying the nature of the mathematical knowledge and the pedagogical content knowledge (PCK) required for effective teaching remains elusive (Ball et al. in J Teacher Educ 59:389–407, 2008). Building on the initial conceptual framework of Magnusson et al. (Examining pedagogical content knowledge, Kluwer, Dordrecht, pp 95–132, 1999), we examined the PCK development for two beginning middle and secondary mathematics teachers in an alternative certification program. The PCK development of these two individuals varied due to their focus on developing particular aspects of their PCK, with one individual focusing on assessment and student understanding, and the other individual focusing on curricular knowledge. Our findings indicate that these individuals privileged particular aspects of their knowledge, leading to differences in their PCK development. This study provides insight into the specific aspects of PCK that developed through the course of actual instructional practice, providing a lens for future research in this area.  相似文献
