This study examined how a contextually based authentic science experience affected the science identities of urban high school students who have been marginalized during their K-12 science education. We examined students’ perceptions of the intervention as an authentic science experience, how the experience influenced their science identity, as well as their perceptions about who can do science. We found that the students believed the experience to be one of authentic science, that their science identity was positively influenced by participation in the experience, and that they demonstrated a shift in perceptions from stereotypical to more diverse views of scientists. Implications for science education are discussed.  相似文献

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.  相似文献

Background: Inquiry learning in science provides authentic and relevant contexts in which students can create knowledge to solve problems, make decisions and find solutions to issues in today’s world. The use of electronic networks can facilitate this interaction, dialogue and sharing, and adds a new dimension to classroom pedagogy.

Purpose: This is a report of teacher and student reflections on some of the tensions, reconciliations and feelings they experienced as they worked together to engage in inquiry learning. The study sought to find out how networked ICT use might offer new and different ways for students to engage with, explore and communicate science ideas within inquiry.

Sample: This project developed case studies with 6 science teachers of year 9 and 10 students, with an average age of 13 and 14 years in three New Zealand high schools. Teacher participants in the project had varying levels of understanding and experience with inquiry learning in science. Teacher knowledge and experience with ICT were equally diverse.

Design and Methods: Teachers and researchers developed initially in a joint workshop a shared understanding of inquiry, and how this could be enacted. During implementation, the researchers observed the inquiry projects in the classrooms and then, together with the teachers, reviewed and analysed the data that had been collected.

Results: At the beginning of the project, some of the teachers and students were tentative: inquiry based teaching supported by ICT meant initially that the teachers were hesitant in letting go some of the control they felt they had over students learning, and the students felt insecure in adopting some responsibility for their own learning. Over time a sense of trust and ease developed and this ‘control of learning’ balance moved from what was traditionally accepted, but not without modifications and reservations.

Conclusions: There is no clear pathway to follow in moving towards ICT-supported science inquiry in secondary schools. The experience of the teacher, the funds of knowledge the students bring to the classroom, the level of technological availability in the school and the ability of the students are all variables which determine the nature of the experience.  相似文献

In this paper we reflect on the article “I am smart enough to study postsecondary science: a critical discourse analysis of latecomers’ identity construction in an online forum”, by Phoebe Jackson and Gale Seiler (Cult Stud Sci Educ.  https://doi.org/10.1007/s11422-017-9818-0). In their article, the authors did a significant amount of qualitative analysis of a discussion on an online forum by four latecomer students with past negative experiences in science education. The students used this online forum as an out-of-class resource to develop a cultural model based on their ability to ask questions together with solidarity as a new optimistic way to position themselves in science. In this forum, we continue by discussing the identity of marginalized science students in relation to resources available in postsecondary science classes. Recent findings on a successful case of a persistent marginalized science student in spite of prior struggles and failures are introduced. Building on their model and our results, we proposed a new cultural model, emphasizing interaction between inside and outside classroom resources which can further our understanding of the identity of marginalized science students. Exploring this cultural model could better explain drop-outs or engagement of marginalized science students to their study. We, then, used this model to reflect on both current traditional and effective teaching and learning practices truncating or re-enforcing relationships of marginalized students with the learning environment. In this way, we aim to further the discussion initiated by Jackson and Seiler and offer possible frameworks for future research on the interactions between marginalized students with past low achievements and other high and mid achieving students, as well as other interactions between resources inside and outside science postsecondary classrooms.  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

ABSTRACT

This study describes multilingual students’ authentic use of their first and second languages in a translanguaging science classroom, from a sociocultural perspective. The study is ethnographic, and has followed some lessons each month in a translanguaging science classroom at a primary school for three years. The observed lessons were documented by four video cameras and four audio recorders, while field notes and different types of students’ texts and other teaching materials were also collected. In order investigate how language operates, and to realise the meaning semantically, we analysed the students’ use of both first and second language to tie paradigmatic relations, and how they move in linguistic loops between languages and discourses. The results illustrate the ways in which a translanguaging science classroom constitutes a resource in joint negotiations of the scientific content and its related language for multilingual students, and benefits the students’ ability to relate and contextualise the science content to prior experience. The creation of translanguaging science classrooms, in which students’ experiences and diverse cultural and linguistic resources interweave with school science, and in which multilingual students are enabled and encouraged to use all available language resources, has important implications for science education.  相似文献

A growing body of teacher identity-based research has begun to embrace that the development of self-understanding about being a teacher is critical to learning how to teach. Construction of a professional teacher identity requires much more beyond mere content, skills and a foundational pedagogy. It also includes an intersection of the personal and professional self, which gives way to the emergence of multiple identities in the classroom. An educator’s gender, nationality, language and interests among other tenets all permeate the classroom field and coexist alongside the professional role identity. This paper aims to use narrative as a way to discuss how science educators can mediate holding several identities in the classroom in order to create an environment characterized by successful teaching and learning. Drawing from an array of sociocultural theoretical perspectives, complementary constructs of identity by Jonathan Turner (Face to face: toward a sociological theory of interpersonal behavior. Stanford University Press, Stanford, CA, 2002) and Amartya Sen (Identity and violence: the illusion of destiny. W. W. Norton, New York, 2006), George Lakoff’s (Metaphors we live by. University of Chicago Press, Chicago, 1980) work on metonymy, and David Bloome’s (2005) theorization of the power of caring relationships, I explore the ways in which my Black female Caribbean identity has transformed the science classroom field and created positive resonance for some of my privileged White students who have Caribbean caretakers at home. To begin, I unpack how Afro-Caribbean immigration to urban centers in the United States continues to produce childcare occupational opportunities in places like New York City. Being a first generation Trinidadian immigrant, my many identities have structured my science teaching praxis and consequently transformed the way my students learn science. A significant part of this paper is a reflexive account of experiences (primarily dialogue) with science students situated both within and outside the science classroom. Conversations with students who were raised through the hired help of Caribbean nannies have revealed that there is a strong resemblance to the way they perceive their caretakers as they do me—their instructor. These conversations serve as a backdrop to illuminate the dynamic nature of identity construction and its relationship to the development of ongoing dialogue. The hope is that this autoethnographic work illustrates the salience of student lifeworlds in affording opportunities for success in the science classroom. Additionally, this research seeks to illustrate how understanding the unconscious ‘backgrounding’ and ‘foregrounding’ of certain identities in the classroom can improve one’s praxis in the urban science classroom and possibly increase student success in science. It is also hoped that this story reiterates the importance of using stories for purposes of scholarship, for moving towards better understandings of the social situations we are concerned to investigate as researchers and for better communication of those understandings.  相似文献

In this article I critically examine the historical context of science education in a natural history museum and its relevance to using museum resources to teach science today. I begin with a discussion of the historical display of race and its relevance to my practice of using the Museum’s resources to teach science. I continue with a critical review of the history of the education department in a natural history museum to demonstrate the historical constitution of current practices of the education department. Using sociocultural constructs around identity formation and transformation, I move to the present with a case study of a teacher who transforms the structure of science education in her classroom and school as a result of her identity transformation and association with a museum-based professional education program.

In this response to Tom G. K. Bryce and Stephen P. Day’s (Cult Stud Sci Educ. doi:10.1007/s11422-013-9500-0, 2013) original article, I share with them their interest in the teaching of climate change in school science, but I widen it to include other contemporary complex socio-scientific issues that also need to be discussed. I use an alternative view of the relationship between science, technology and society, supported by evidence from both science and society, to suggest science-informed citizens as a more realistic outcome image of school science than the authors’ one of mini-scientists. The intellectual independence of students Bryce and Day assume, and intend for school science, is countered with an active intellectual dependence. It is only in relation to emerging and uncertain scientific contexts that students should be taught about scepticism, but they also need to learn when, and why to trust science as an antidote to the expressions of doubting it. Some suggestions for pedagogies that could lead to these new learnings are made. The very recent fifth report of the IPCC answers many of their concerns about climate change.  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

This ethnographic study at a public high school in the Northeastern United States investigates the process of change in students’ environmental identity and proenvironmental behaviors during an Environmental Science course. The study explores how sociocultural factors, such as students’ background, social interactions, and classroom structures, impact the environmental identity and behavior of students. In this investigation, the identity theory of emotion of Stryker (2004) from the field of sociology is utilized in the interpretation of students’ reactions to classroom experiences as they proceed through the Environmental Science course. The participants in this study are an Environmental Science teacher and the 10–12th grade students in her Environmental Science elective course. The researcher collected data for a period of six months, attending class on a daily basis. Data was collected through participant observation, videotaping, interviews, and cogenerative dialogues. The results of this study inform science educators by illuminating important elements, such as students’ emotional responses to activities in class, conflicting elements of students’ identities, and students’ openness and willingness to critically reflect upon new information, which contribute to whether a student is likely to change their views towards the environment and pro-environmental behaviors.  相似文献

Steven Vertovec (2006, 2007) has recently offered a re-interpretation of population diversity in large urban centres due to a considerable increase in immigration patterns in the UK. This complex scenario called superdiversity has been conceptualised to help illuminate significant interactions of variables such as religion, language, gender, age, nationality, labour market and population distribution on a larger scale. The interrelationships of these themes have fundamental implications in a variety of community environments, but especially within our schools. Today, London schools have over 300 languages being spoken by students, all of whom have diverse backgrounds, bringing with them a wealth of experience and, most critically, their own set of religious beliefs. At the same time, Science is a compulsory subject in England’s national curriculum, where it requires teachers to deal with important scientific frameworks about the world; teaching about the origins of the universe, life on Earth, human evolution and other topics, which are often in conflict with students’ religious views. In order to cope with this dynamic and thought-provoking environment, science initial teacher education (SITE)—especially those catering large urban centres—must evolve to equip science teachers with a meaningful understanding of how to handle a superdiverse science classroom, taking the discourse of inclusion beyond its formal boundaries. Thus, this original position paper addresses how the role of SITE may be re-conceptualised and re-framed in light of the immense challenges of superdiversity as well as how science teachers, as enactors of the science curriculum, must adapt to cater to these changes. This is also the first in a series of papers emerging from an empirical research project trying to capture science teacher educators’ own views on religio-scientific issues and their positions on the place of these issues within science teacher education and the science classroom.  相似文献

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students’ interests in participating in opportunities to do real science? What are the discursive resources they draw on to introduce authentic science to students? The purpose of this ethnographic and discourse-analytic study is to investigate the ways in which the activities of scientists are discursively presented to high school students in a biology/career preparation course. Data sources were collected by means of observation, field notes, interviews, and videotaped lessons in an eleventh-grade biology/career preparation course. Drawing on discourse analysis, we investigate the discursive resources—or, more specifically and technically, the interpretative repertoires—teachers used to explain and promote opportunities to engage students in real science activities. Our analysis identifies and characterizes six types of interpretative repertoires: specialized, a-stereotypical, relevant, empirical, emotive, and rare-opportunity. To better understand the “big picture” of how these discursive resources are drawn on in the classroom, we also report on the frequencies of the repertoires in the discourse and the ways in which repertoires changed in the course of teacher-student interactions. The findings of this case study offer teachers and researchers with a better understanding of how specific forms of discourse—i.e., the repertoires—can serve as resources to enhance teacher-introduction of authentic science to students and provide students a bridge between school and authentic science.  相似文献

Research on understanding the full extent that an authentic science research experience engages students in how scientists think and act is sparse. ‘Learning-science-by-doing-science’ (LSDS) is an emerging self-guided process-learning model in postsecondary science education. It offers authentic science research opportunities that drive students to think and act like scientists. This study investigates the LSDS approach as a potential model for science learning at postsecondary level and aims to answer a main research inquiry – what are the students’ and teaching staff’s perceptions of students’ learning gains and the quality of their learning experiences in an authentic research environment within the LSDS model? To answer this question, data were collected from the students, alumni, instructors, teaching assistants and the program director via questionnaires, focus groups and interviews. Students’ and staff’s lived experiences and their perceptions on their authentic research experiences within the LSDS model were used to articulate the key attributes and stages of the LSDS model. The outcomes of this study can be used to help other science programs implement similar authentic research process learning approaches in their own contexts.  相似文献

This paper is written in response to Angela Chapman and Allan Feldman’s research study, “Cultivation of science identity through authentic science in an urban high school”. I utilize this forum piece to extend the call for “awakening a dialogue” that critically assesses the effectiveness of current K-12 science education research in addressing the needs of populations of color. I take the opportunity to first discuss elements of what an equitable research focus might look like. I finish by critiquing and ultimately commending the authors on the degree to which they succeed in demonstrating an equitable approach to the design and carrying out of their study.  相似文献

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.

Science enrichment programmes housed outside traditional school settings offer unique opportunities to access and use authentic scientific tools and practices, especially for urban students whose school science experiences often lack resources. Yet opportunities to access these tools and practices are realized only when science teachers value them sufficiently to take advantage of them. This study examines how eight urban secondary science teachers evaluated a specific out‐of‐school science enrichment programme—a one‐year partnership with a local university science outreach centre, which culminated in a half‐day laboratory experience for their students. Teachers’ perceptions were captured through interviews and surveys. Findings indicate that these teachers came to identify and value many of the potential benefits for out‐of‐school enrichment programmes reported in the literature as well as some additional ones. The teachers’ also showed a shift over time with respect to their perceptions of the value of the out‐of‐school experience, moving from an initial focus on increasing test scores toward a greater appreciation for its impact on students’ motivation and identity development. The study offers insight into secondary science students’ and teachers’ identity needs, and what universities can offer to address them.  相似文献
