This investigation explores how underrepresented urban students made sense of their first experience with high school science. The study sought to identify how students' assimilation into the science classroom reflected their interpretation of science itself in relation to their academic identities. The primary objectives were to examine students' responses to the epistemic, behavioral, and discursive norms of the science classroom. At the completion of the academic year, 29 students were interviewed regarding their experiences in a ninth and tenth‐grade life science course. The results indicate that students experienced relative ease in appropriating the epistemic and cultural behaviors of science, whereas they expressed a great deal of difficulty in appropriating the discursive practices of science. The implications of these findings reflect the broader need to place greater emphasis on the relationship between students' identity and their scientific literacy development. © 2005 Wiley Periodicals, Inc.

This study explores how students' physics identities are shaped by their experiences in high school physics classes and by their career outcome expectations. The theoretical framework focuses on physics identity and includes the dimensions of student performance, competence, recognition by others, and interest. Drawing data from the Persistence Research in Science and Engineering (PRiSE) project, which surveyed college English students nationally about their backgrounds, high school science experiences, and science attitudes, the study uses multiple regression to examine the responses of 3,829 students from 34 randomly selected US colleges/universities. Confirming the salience of the identity dimension for young persons' occupational plans, the measure for students' physics identity used in this study was found to strongly predict their intended choice of a physics career. Physics identity, in turn, was found to correlate positively with a desire for an intrinsically fulfilling career and negatively with a desire for personal/family time and opportunities to work with others. Physics identity was also positively predicted by several high school physics characteristics/experiences such as a focus on conceptual understanding, real‐world/contextual connections, students answering questions or making comments, students teaching classmates, and having an encouraging teacher. Even though equally beneficial for both genders, females reported experiencing a conceptual focus and real‐world/contextual connections less frequently. The explicit discussion of under‐representation of women in science was positively related to physics identity for female students but had no impact for male students. Surprisingly, several experiences that were hypothesized to be important for females' physics identity were found to be non‐significant including having female scientist guest speakers, discussion of women scientists' work, and the frequency of group work. This study exemplifies a useful theoretical framework based on identity, which can be employed to further examine persistence in science, and illustrates possible avenues for change in high school physics teaching. © 2010 Wiley Periodicals, Inc.

Sexual health is a controversial science topic that has received little attention in the field of science education, despite its direct relevance to students' lives and communities. Moreover, research from other fields indicates that a great deal remains to be learned about how to make school learning about sexual health influence the real‐life choices of students. In order to provide a more nuanced understanding of young people's decision‐making, this study examines students' talk about sexual health decision‐making through the lens of identities. Qualitative, ethnographic research methods with twenty 12th grade students attending a New York City public school are used to illustrate how students take on multiple identities in relation to sexual health decision‐making. Further, the study illustrates how these identities are formed by various aspects of students' lives, such as school, family, relationships, and religion, and by societal discourses on topics such as gender, individual responsibility, and morality. The study argues that looking at sexual health decision‐making—and at decision‐making about other controversial science topics—as tied to students' identities provides a useful way for teachers and researchers to grasp the complexity of these decisions, as a step toward creating curriculum that influences them. © 2010 Wiley Periodicals, Inc.

A view of science as a culturally‐mediated way of thinking and knowing suggests that learning can be defined as engagement with scientific practices. How students engage in school science is influenced by whether and how students view themselves and whether or not they are the kind of person who engages in science. It is therefore crucial to understand students' identities and how they do or do not overlap with school science identities. In this paper, we describe four middle school African American girls' engagement with science. They were selected in the 7th grade because they expressed a fondness for science in school or because they had science‐related hobbies outside of school. The data were collected from the following sources: interviews of students, their parents and their teachers; observations in science classes; journal writing; and focus groups. These girls' stories provide us with a better understanding of the variety of ways girls choose to engage in science and how this engagement is shaped by their views of what kind of girl they are. © 2000 John Wiley & Sons, Inc.

This study examined the relationship between students' out‐of‐school experiences and various factors associated with science learning. Participants were 1,014 students from two urban high schools (secondary schools). They completed a survey questionnaire and science assessment describing their science learning experiences across contexts and science understanding. Using multilevel statistical modelling, accounting for the multilevel structure of the data with students (Level 1) assigned to teachers (Level 2), the results indicated that controlling for student and classroom factors, students' ability to make connections between in‐school and out‐of‐school science experiences was associated with positive learning outcomes such as achievement, interest in science, careers in science, self‐efficacy, perseverance, and effort in learning science. Teacher practice connecting to students' out‐of‐school experiences was negatively associated with student achievement but has no association with other outcome measures. The mixed results found in this study alert us to issues and opportunities concerning the integration of students' out‐of‐school experiences to classroom instruction, and ultimately improving our understanding of science learning across contexts.  相似文献

This study examined the degree to which individual differences in students' (N = 232) concepts of size and scale are explained by factors such as students' innate sense of number, out‐of‐school science experiences, exposure to size and scale instruction, gender identities, and racial/ethnic identities. There is increasing emphasis being placed on the use of crosscutting concepts to promote deep learning in science. A multiple linear regression indicated students' racial/ethnic identities, experiences with scale outside of school, and exposure to size and scale instruction significantly added to the prediction model. Results from this study can both inform the movement toward incorporating crosscutting concepts into pedagogy as well as inform educators, administrators, and other stakeholders of the factors that may shape students' understanding of the cross‐cutting concept of scale, proportion, and quantity.  相似文献

In this study, we develop a model of science identity to make sense of the science experiences of 15 successful women of color over the course of their undergraduate and graduate studies in science and into science‐related careers. In our view, science identity accounts both for how women make meaning of science experiences and how society structures possible meanings. Primary data included ethnographic interviews during students' undergraduate careers, follow‐up interviews 6 years later, and ongoing member‐checking. Our results highlight the importance of recognition by others for women in the three science identity trajectories: research scientist; altruistic scientist; and disrupted scientist. The women with research scientist identities were passionate about science and recognized themselves and were recognized by science faculty as science people. The women with altruistic scientist identities regarded science as a vehicle for altruism and created innovative meanings of “science,” “recognition by others,” and “woman of color in science.” The women with disrupted scientist identities sought, but did not often receive, recognition by meaningful scientific others. Although they were ultimately successful, their trajectories were more difficult because, in part, their bids for recognition were disrupted by the interaction with gendered, ethnic, and racial factors. This study clarifies theoretical conceptions of science identity, promotes a rethinking of recruitment and retention efforts, and illuminates various ways women of color experience, make meaning of, and negotiate the culture of science. © 2007 Wiley Periodicals, Inc.

The purpose of this study is to explore smartness and talent as social constructs. Drawing on Holland et al.'s (1998) figured identities, this article explores the figuring of abilities by elucidating the voices of African American high school chorus students. Critical Race Theory (CRT) helps to unpack normalized language and practices that comprise intelligence, talent, and identity construction. The student participants in this study contrasted high school experiences in which they constructed musical and academic identities, describing how smart or talented they were relative to significant others around them. Findings suggest that constructions of musical talent and smartness socially positioned students along race, gender, and class lines. Interpretations of talent and intelligence may impact the curricular options made available to students, their academic identity construction, musical identity construction, and inequitable school practices.  相似文献

This article is an investigation of art and design graduates' identities as they embark upon their training as teachers. The expressive, ‘confessional’ nature of forum posts from their Virtual Learning Environment are analysed in relation to the students' identity transformation into teachers. This transition is profound in the case of artist teachers, for whom the contrast between their practice as a critical artist and that of a regulated professional can be severe. The usage of these socially‐oriented virtual forums, and the students' identity transition is analysed in terms of identity theorists such as Butler, hooks and Wenger. There are problems of expression that are brought about by the juxtaposition of visually and spatially adept artist‐learners constrained within a largely textual environment, yet this impediment appears to be ameliorated by their social‐expressive exploitation of the forums.  相似文献

School‐based assessment of science students' practical skills has two important roles—as a complement to written papers in public examinations and as a catalyst for enriching the science curriculum in schools. This article describes a quantitative study of the concerns chemistry and biology teachers experience as they engage in the process of implementation of a school‐based assessment scheme for practical work. A 23‐item questionnaire was developed to measure five categories of teacher concern: evaluation, information, management, consequence and refocusing. The nature of each category of teacher concern is discussed in relation to innovation adoption and implementation. Data were collected from 400 chemistry and 412 biology teachers in Hong Kong. Teachers' information and management concerns lessened in intensity when they became experienced users of a school‐based assessment scheme. However, teaching experience alone could not motivate teachers to think more about the impact of school‐based assessment on student learning, their professional development in student assessment and the possible refinements in their school‐based assessment scheme. Concerns‐based interventions are suggested to help teachers grow professionally.  相似文献

The ‘promposal’ is a growing, North American high school ritual in which one graduating senior asks another to the prom in a creative, witty, public performance that is recorded and posted online. A YouTube search for ‘promposal’ yields over 49,000 hits, with videos receiving up to 8,000,000 views. What does the promposal reveal about the construction of gender and identity amongst teenagers in the digital era and the nature of the voices channelled, expressed or spoken? In a study of high school students' responses to the promposal as well as a discourse analysis of YouTube videos, this paper argues that: students use promposals to achieve social aims by constructing and presenting desirable identities and voices across multiple platforms; the performances of gender seen in online promposals tend to draw upon, reflect, and reify traditional, hegemonic patterns of behaviour and to amplify the male voice; and promposals are a means of announcing the debut of young people as productive contributors to the neo-liberal economy as they prepare to leave high school.  相似文献

This study follows an ethnically and economically diverse sample of 33 high school students to explore why some who were once very interested in science, engineering, or medicine (SEM) majors or careers decided to leave the pipeline in high school while others persisted. Through longitudinal interviews and surveys, students shared narratives about their developing science identities, SEM participation and aspirations. In analysis, three groups emerged (High Achieving Persisters, Low Achieving Persisters, and Lost Potentials), each experiencing different interactions and experiences within science communities of practice in and outside of school and within the extended family. These different microclimates framed students' perceptions of their SEM study, abilities, career options, and expected success, thereby shaping their science identities and consequent SEM trajectories. School science was often hard and discouraging; there were very few science advocates at school or home; and meaningful opportunities to work with real science professionals were scarce, even in schools with science or health academies. Students expressed positive attitudes toward science and non‐science pursuits where they experienced success and received support from important people in their lives. Results underscore the key role communities of practice play in career and identity development and suggest a need for interventions to help socializers better understand the value and purpose of science literacy themselves so as to encourage students to appreciate science, be aware of possible career options in science and enjoy learning and doing science. © 2009 Wiley Periodicals, Inc.

In evaluating teachers' instructional decisions during instruction, it is clear that the nature of their elicitation is crucial for student learning. When instructional decisions are informed by information about students' conceptual understanding, significant learning is possible. This article examined the elicitation practices of two high school science teachers who indicated that they made instructional decisions based on the elicited evidence of students' knowledge but whose elicitation practices were characteristic of low-level elicitation. The teachers focused on students' responses that used canonical terms and expressed acceptable knowledge. The teachers demonstrated low-level responsiveness because they did not have full access to students' knowledge. The elicited evidence of students' knowledge that was used in making instructional decisions was not representative of students' conceptual understanding. There was, thus, a mismatch between the teachers' perspectives about their formative assessment practice and what is considered effective formative assessment.  相似文献

This article describes qualitative and quantitative assessment based on responses of 221 teachers from nine elementary schools in two districts (urban and suburban) to inform plans for reducing and preventing student aggression. Teachers' perceptions of students' aggressive behavior and beliefs were validated against students' self‐reports and archival disciplinary data. Using a brief survey, we found district‐ and grade‐level differences in teachers' perceptions of students' aggressive behavior and aggression supporting cognitions. Teacher reports on these two constructs each uniquely predicted teacher perceptions of the degree to which student aggression interferes with their jobs. Focus‐group interviews with teachers were used to elaborate on individual‐cognitive and ecological school factors related to student aggression, including procedures for handling aggression. The importance of teacher reports is highlighted, and implications for school program development are considered. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 331–344, 2006.  相似文献

The idea of using science notebooks as a classroom assessment tool is not new. There is general agreement that science notebooks allow teachers to assess students' conceptual and procedural understanding and to provide the feedback students need for improving their performance. In this study we examined the use of science notebooks as an unobtrusive assessment tool that can also be used by individuals outside the classroom (for example, school district personnel), and as a means for obtaining information about students' learning and their opportunities to learn. More specifically, in this study students' science notebooks were used as a source of data about the (a) implementation of a curriculum's intended activities, (b) students' performance, and (c) quality of teachers' feedback. Our results indicated that: (1) Students' science notebooks can be reliably scored. Unit implementation, student performance, and teacher feedback scores were highly consistent across raters and units. (2) High and positive correlations with other performance assessment scores indicated that the student performance score can be considered as an achievement indicator. And (3) low performance scores across the two units revealed that students' communication skills and understanding were far away from the maximum score and did not improve over the course of instruction during the school year. This result may be due, in part, to the fact that no teacher feedback was found in any of the students' notebooks across the six classrooms studied. This may reflect some characteristics of the teachers' assessment practices that may require further professional development.  相似文献

Science includes more than just concepts and facts, but also encompasses scientific ways of thinking and reasoning. Students' cultural and linguistic backgrounds influence the knowledge they bring to the classroom, which impacts their degree of comfort with scientific practices. Consequently, the goal of this study was to investigate 5th grade students' views of explanation, argument, and evidence across three contexts—what scientists do, what happens in science classrooms, and what happens in everyday life. The study also focused on how students' abilities to engage in one practice, argumentation, changed over the school year. Multiple data sources were analyzed: pre‐ and post‐student interviews, videotapes of classroom instruction, and student writing. The results from the beginning of the school year suggest that students' views of explanation, argument, and evidence, varied across the three contexts with students most likely to respond “I don't know” when talking about their science classroom. Students had resources to draw from both in their everyday knowledge and knowledge of scientists, but were unclear how to use those resources in their science classroom. Students' understandings of explanation, argument, and evidence for scientists and for science class changed over the course of the school year, while their everyday meanings remained more constant. This suggests that instruction can support students in developing stronger understanding of these scientific practices, while still maintaining distinct understandings for their everyday lives. Finally, the students wrote stronger scientific arguments by the end of the school year in terms of the structure of an argument, though the accuracy, appropriateness, and sufficiency of the arguments varied depending on the specific learning or assessment task. This indicates that elementary students are able to write scientific arguments, yet they need support to apply this practice to new and more complex contexts and content areas. © 2011 Wiley Periodicals, Inc.

This article examines interview talk of three students in an Australian high school to show how they negotiate their young adult identities between school and the outside world. It draws on Bakhtin's concepts of dialogism and heteroglossia to argue that identities are linguistically and corporeally constituted. A critical discourse analysis of segments of transcribed interviews and student-related public documents finds a mismatch between a social justice curriculum at school and its transfer into students' accounts of outside school lived realities. The article concludes that a productive social justice pedagogy must use its key principles of (con)textual interrogation to engage students in reflexive practice about their positioning within and against discourses of social justice in their student and civic lives. An impending national curriculum must decide whether or not it negotiates the discursive divide any better.  相似文献
