This paper explores the different ways that primary school teachers in Uganda navigate the boundary between school science and everyday knowledge in the context of a centrally mandated curriculum innovation. The paper is based on a study of the pedagogic practices of 16 teachers in eight Ugandan primary schools that were selected on the basis of having a track record of either high or low academic achievement in the public primary school‐leaving examination. The official primary school curriculum in Uganda prescribes that science be taught in an integrated form, including integration between science subject knowledge and everyday knowledge. The strategies that teachers in the study adopted in relating science to everyday knowledge was a key feature that differentiated between pedagogic practices in the high‐performing and low‐performing schools. In high‐performing schools, teachers recruited everyday knowledge as a resource for learning science as a specialised discourse; whereas in the low‐performing schools, acquiring everyday knowledge was viewed as an end in itself. The paper, then, considers the implications of differences in teachers' pedagogic strategies for the kinds of knowledge to which learners are given access.  相似文献

Presenting science is an authentic activity of practicing scientists. Thus, effective communication of science is an important skill to nurture in high school students who are learning science. This study examines strategies employed by high school students as they make science presentations; it assesses students' conceptual understandings of particular science topics through their presentations and investigates gender differences. Data are derived from science presentation given by eight high school students, three females and five males who attended a summer science program. Data sources included videotaped presentations, ethnographic fieldnotes, interviews with presenters and members of the audience, and presenter notes and overheads. Presentations were transcribed and submitted to discourse analysis from an interactional sociolinguistic perspective. This article focuses on the methodology employed and how it helps inform the above research questions. The author argues that use of this methodology leads to findings that inform important social-communicative issues in the learning of science. Practical advice for teaching students to present science, implications for use of presentations to assess conceptual learning, and indications of some possible gender differences are discussed.  相似文献

The inadequate number of American young adults selecting a scientific or engineering profession continues to be a major national concern. Using data from the 23-year record of the Longitudinal Study of American Youth (LSAY) and working within the social learning paradigm, this analysis uses a set of 21 variables to predict young people's employment in science, technology, engineering, mathematics, or medicine (STEMM) at ages 36 to 39. The LSAY is one of the longest and most intensive longitudinal studies of the impact of secondary education and postsecondary education conducted in the United States. Using a structural equation model, the study found that mathematics continues to be a primary gateway for STEMM professions, beginning with algebra track placement in grade eight and continuing through high school and college calculus courses. Home and family factors such as parent education and parent encouragement of science and mathematics during secondary school also enhanced the likelihood of entering a STEMM profession.  相似文献

In this paper I consider a role for risk understanding in school science education. Grounds for this role are described in terms of current sociological analyses of the contemporary world as a ‘risk society’ and recent public understanding of science studies where science and risk are concerns commonly linked within the wider community. These concerns connect with support amongst many science educators for the goal of science education for citizenship. From this perspective scientific literacy for decision making on contemporary socioscientific issues is central. I argue that in such decision making, risk understanding has an important role to play. I examine some of the challenges its inclusion in school science presents to science teachers, review previous writing about risk in the science education literature and consider how knowledge about risk might be addressed in school science. I also outline the varying conceptions of risk and suggest some future research directions that would support the inclusion of risk in classroom discussions of socioscientific issues.  相似文献

In this study, we present the long-term influence of an after school science practicum associated with an elementary science methods course. The practicum or field experience could be considered a community-based service learning programme as it is situated both within and for the community. Study participants included eight third- and fifth-grade teachers who had participated in elementary science methods courses; four of these teachers participated in the after school teaching practicum while four participants experienced a more traditional observation-based elementary science practicum. All of these teachers were in their second or third year teaching which was 3–4 years after taking the methods course. Investigation methods included questionnaires, field observations and semi-structured, individual interviews. Teachers more regularly utilised reform-based teaching strategies and cited the after school teaching practicum as preparing them to use these strategies in their own classrooms. All teachers exhibited a growth mindset to some degree, but the after school practicum participants did demonstrate a wider use of reformed-based teaching strategies and a higher growth mindset. Elementary teachers perceive risk associated with these key aspects of instruction: (1) managing instruction and classroom management, (2) teaching science through guided inquiry, and (3) overcoming adoptions in other ‘mandated’ curriculum like math and reading.  相似文献

This is an ethnographic study of a newly created math, science, and technology elementary magnet school in a rural community fiercely committed to cultural preservation while facing unprecedented economic instability brought on by massive loss of manufacturing jobs. Our goal was to understand global- and community-level contexts that influenced the school’s science curriculum, the ways the school promoted itself to the community, and the implicit meanings of science held by school staff, parents and community members. Main sources of data were the county’s newspaper articles from 2003 to 2006, the school’s, town’s, and business leaders’ promotional materials, and interviews with school staff, parents, and community members. A key finding was the school’s dual promotion of science education and character education. We make sense of this “science with character” curriculum by unpacking the school and community’s entanglements with historical (cultural preservation), political (conservative politics, concerns for youth depravity), and economic (globalization) networks. We describe the ways those entanglements enabled certain reproductive meanings of school science (as add-on, suspect, and elitist) and other novel meanings of science (empathetic, nurturing, place-based). This study highlights the school as a site of struggle, entangled in multiple networks of practice that influence in positive, negative, and unpredictable ways, the enacted science curriculum.  相似文献

Many researchers consider a lacking interest in science and the students' belief that science is too demanding as major reasons why young people do not strive for science-related careers. In this article, we first delineated a theoretical framework to investigate the importance of interest, self-concept, and school factors regarding students' career preferences. Then, we tested the expected effects on a sample of German 9th-grade students (N = 7,813). We focused on two school factors: the amount of (additional) science activities and the real-life applications in science classes. The multi-level analysis showed that school factors were highly relevant for the students' interest in science and science self-concept. In turn, interest in science and science self-concept affect the students' interest in science-related careers. We conclude that focusing on the link between individual and school characteristics is important for the understanding of students' interest in science-related careers.  相似文献

This study demonstrates the potential for collaborative research among participants in local settings to effect positive change in urban settings characterized by diversity. It describes an interpretive case study of a racially, ethnically, and socioeconomically diverse eighth grade science classroom in an urban magnet school in order to explore why some of the students did not achieve at high levels and identify with school science although they were both interested in and knowledgeable about science. The results of this study indicated that structural issues such as the school's selection process, the discourses perpetuated by teachers, administrators, and peers regarding “who belongs” at the school, and negative stereotype threat posed obstacles for students by highlighting rather than mitigating the inequalities in students' educational backgrounds. We explore how a methodology based on the use of cogenerative dialogues provided some guidance to teachers wishing to alter structures in their classrooms to be more conducive to all of their students developing identities associated with school science. Based on the data analysis, we also argue that a perspective on classrooms as communities of practice in which learning is socially situated rather than as forums for competitive displays, and a view of students as valued contributors rather than as recipients of knowledge, could address some of the obstacles. Recommendations include a reduced emphasis on standardized tasks and hierarchies, soliciting unique student contributions, and encouraging learning through peripheral participation, thereby enabling students to earn social capital in the classroom. © 2010 Wiley Periodicals, Inc.

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.  相似文献

This article explores school leadership for elementary school science teaching in an urban setting. We examine how school leaders bring resources together to enhance science instruction when there appear to be relatively few resources available for it. From our study of 13 Chicago elementary (K–8) schools' efforts to lead instructional change in mathematics, language arts, and science education, we show how resources for leading instruction are unequally distributed across subject areas. We also explore how over time leaders in one school successfully identified and activated resources for leading change in science education. The result has been a steady, although not always certain, development of science as an instructional area in the school. We argue that leading change in science education involves the identification and activation of material resources, the development of teachers' and school leaders' human capital, and the development and use of social capital. © 2001 John Wiley & Sons, Inc.

This article on secondary schools science laboratories in Portugal focuses on how school space functions as a pedagogical and political instrument by contributing to shape the conditions for teaching and learning dynamics. The article places the impact of changes to school layouts within the larger context of a public school renovation programme, discussing how school space functions as a pedagogical and political instrument. The focus is on science laboratories as a particular learning environment for science education. The study, conducted between 2010 and 2011 in 13 renovated schools within the framework of the Portuguese Secondary School Modernisation Programme, drew on document analysis, interviews, pupil and teacher surveys and site-specific focus groups. One of the main findings is that teachers found that science laboratories were the most controversial and debated of all the renovated learning spaces. Considering that the science laboratory layout was intended to be universal across all schools, there was little intervention by the architects responsible for the renovation of the schools. Focusing on the analysis of the decision to change the science laboratory design within the aims of the education policy, this article discusses how teachers’ criticisms were a response to some of the educational policy goals underlying the renovation of school buildings and the potential impact on science education, namely, the relationship between flexibility of space organisation and pedagogical approaches.  相似文献

In an attempt to accelerate the development of formal operations in average young adolescents, intervention lessons relating to all formal schemata were designed in the context of school science courses. Over a period of two years, up to 30 intervention lessons were given by science teachers to their classes in eight schools. Boys who started the program aged 12+ showed a pre-posttest effect size on Piagetian tests of 0.89 SD compared with control classes. In terms of British norms for the development of operational thinking this was a mean change from the 51st to the 74th percentile. Neither the middle school students nor the 12+ girls showed greater gain than the controls. Gains were shown by girls in one 11+ class and in the two 11+ laboratory classes. In the laboratory school students given intervention lessons by the researchers maintained their gains over controls in formal operations at a delayed posttest one year after cessation of the program. There was no effect on tests of science achievement during the intervention. It was argued that the interventions needed to be accompanied by in-service training designed to enable teachers to change their teaching style in line with their students' increased operational thinking capacity.  相似文献

This study investigated students’ perceptions of the generalist learning environment of the primary school compared to their perceptions of the specialist science learning environment of secondary school. The role of student gender and change in school size as influencing factors on changes in students’ perceptions across primary to secondary transition were especially considered. The same students’ perceptions of the learning environment were collected in the final stages of primary school and again after their initial term in secondary school. Insights were gained into how students’ perceptions of learning environment changed during their first exposure to specialised science learning environments and teachers, and how these changes in perceptions during transition depended upon school size and student gender. Both school size and student gender were found to be influencing factors for changes in some learning environment dimension perceptions.  相似文献

This study describes the resources and strategies middle school teachers, urban fellows, and a district science staff developer coactivated to resist the marginalization of science in a high‐poverty, low‐performing urban school. Through critical narrative inquiry, I document factors that marginalized science in three teachers' classrooms. The narratives show that constraints related to cultural, material, and social resources contributed to a more global symbolic resource constraint, the low status and priority of science in the school. The narratives develop a new category of strategic resources embodied or controlled by others and leveraged to improve students' opportunities to learn science. Attention to a broader array of resources, including social, symbolic, and strategic resources, helps to excavate some of the inertial forces that might derail efforts to teach for social justice. The findings provide a sense of how and why teachers might activate resources to resist the marginalization of science in their classrooms. © 2009 Wiley Periodicals, Inc.

This article is a report of elementary school teachers' beliefs about and uses of text material in science. Survey results from 522 K-8 teachers from 299 schools in the United States, Puerto Rico and the Virgin Islands were analyzed along three dimensions: teacher attitudes toward teaching of reading in science; teacher beliefs and understanding about models of reading, factors influencing science reading and reading skills; and teacher use of various teaching strategies. Results suggest that teachers do not see reading science as different from any other narrative material. And though most agreed to the importance of having students do activities to support and enhance the use of text material, responses suggest that covering topics is still a concern for most elementary teachers.  相似文献

Using data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (N = 4447), this analysis employs an opportunity-propensity (O-P) framework (Byrnes, 2003; Byrnes & Miller, 2007; Byrnes & Wasik 2009) to examine the influence of multiple student, teacher, classroom, and school factors on eighth-grade science achievement. Saçkes, Trundle, Bell, and O’Connell (2011) fit an O-P structural equation model (SEM) to the same database to explain science achievement growth from Kindergarten to third grade. We extend this work by fitting an O-P SEM to this database to predict science achievement growth from fifth to eighth grade. This middle school model includes an opportunity variable – science curriculum track placement – that operates only in middle and high school. This variable and the school’s poverty rate are significant predictors of several opportunity factors. We replicate previous findings that propensity factors are the strongest determinants of science achievement, notably prior achievement. However, we find more opportunity factors than previous studies that are also significant. Other things being equal, having a state-certified teacher is the second strongest predictor of achievement within the model. Placement in a science honors course and being enrolled in a low income school are also linked to small but significant impacts on science achievement.  相似文献

Iowa students and parents completed related attitude and belief questionnaires about school subjects. Grade K–3 students received simpler questionnaires than did Grade 4–6 students or parents. Among Grade 4–6 children, girls perceived higher competence in reading than did boys, but boys perceived higher competence in physical science. All children perceived physical science competence lower than reading or math competence. Parents perceived boys as more competent in science. Girls like reading more than boys did; boys and girls did not differ in liking of science. Grade 4–6 children also expected lower grades in and attached lower importance to physical science than to reading. Parents perceived science as more important for boys and expected higher performance of boys. Jobs related to math or science were seen as more male dominated. These results provided a more comprehensive picture of attitudes and beliefs about science in the elementary school than had existed and suggested that attitudinal gender differences related to physical science begin to develop by the earliest elementary school years. Policy implications are that intervention programs designed to promote gender equity should be extended to the early elementary school years and also should address parental attitudes. Additional implications for policy and research are discussed. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 719–747, 1999  相似文献

This ethnographic study examined how rural, lower track, underrepresented students made sense of their place in school and what role school science played in their cultural reproduction. The objectives of the study were to identify key components of science classroom discourse, analyze means of negotiating these components, and explicate participants' beliefs and roles in defining microcultural identities specific to rural, underrepresented school contexts. Eight students and their teacher participated in this study, which drew heavily upon teacher and student revoicing of common events. Results showed that the quality of science instruction was subverted through a process of negotiation between students and teachers in the context of low expectations and the school culture. Implications for research and practice are discussed. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 574–598, 2001  相似文献

Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion.  相似文献
