This study examines students’ use of proportional reasoning in high school physics problem‐solving in a West African school setting. An in‐depth, constructivist, and interpretive case study was carried out with six physics students from a co‐educational senior secondary school in Nigeria over a period of five months. The study aimed to elicit students’ meanings, claims, concerns, constructions, and interpretations of their difficulty with proportional reasoning as they worked on a series of 18 high school physics tasks. Multiple qualitative research techniques were employed to generate, analyse, and interpret data. Results indicated that several socio‐cultural, psychosocial, cognitive, and mathematical issues were associated with students’ use of proportional reasoning in physics. Students’ capacity to reason proportionally was not only linked to their difficulty with the concept, structure, and strategies of proportional reasoning as a learning and problem‐solving skill, but was also embedded in the social, cultural, cognitive, and contextual elements involved in the learning of physics. The study concludes with a discussion of the implications for teaching high school physics.  相似文献

“I Didn't Do Nothin'”: The Discursive Construction of School Suspension   总被引:1,自引:0,他引:1  
Vavrus  Frances  Cole  KimMarie 《The Urban Review》2002,34(2):87-111
This article examines the issue of school suspension by looking at the sociocultural factors that influence a teacher's decision to remove a student from the classroom. The authors use ethnographic and discourse analytic approaches to study how disciplinary moments are constructed by teachers and students in an urban high school in the Midwest. The analysis of classroom observations, videotaped lessons, and interviews from a longitudinal study at this multiethnic high school shows that suspensions frequently occur in the absence of any physical violence or blatant verbal abuse. Rather, suspensions are often preceded by a complex series of nonviolent events when one disruptive act among many is singled out for action by the teacher. This study has implications for current debates about zero-tolerance policies that disproportionately affect students of color for their misbehavior in school. Our analysis suggests that removing a student from class is a highly contextualized decision based on subtle race and gender relations that cannot be adequately addressed in school discipline policies.  相似文献

High school students who participate in social justice education have a greater awareness of inequities that impact their school, community, and society, and learn tools for taking action to address these inequities. Also, a classroom that consist of students with a diverse set of identities creates an ideal circumstance in which a teacher can build upon student differences in order to facilitate meaningful discussions about social justice, especially issues of race. Therefore, in this article we use qualitative case study approaches to examine a high school course on social justice education, paying specific attention to the classroom pedagogy and dialogue on issues of race, power, and privilege. The course was purposefully diverse in enrollment, which brought students together who might not have had interactions with each other prior to the class. We employ Hackman's (2005) five components of social justice education (SJE) as a framework for the analysis of the pedagogy and discussions constructed in the classroom, as well as a common language for what constitutes as social justice education in our research inquiry. Students in the course developed a facility for defining and identifying various forms of oppression and injustice. However, we questioned to what extent these very same issues played out in the class dialogue. Due to the level of student diversity, the course was a unique space to learn about racism and intersecting issues of social justice. However, there was still some student resistance to acknowledging certain aspects of racism. In conclusion, we discuss how social justice education is not absolved from, but rife with complex racial politics.  相似文献

Environment and environmental protection are on the forefront of political concerns globally. But how are the media and political discourses concerning these issues mirrored in the public more generally and in the discourses of school science students more specifically? In this study, we analyze the discourse mobilized in whole-class conversations of and interviews with 15- to 16-year-old Swiss junior high school students. We identify two core interpretive repertoires (each unfolding into two second-order repertoires) that turn out to be the building blocks of environmental discourse, which is characteristic not only of these students but also of Swiss society more generally. The analysis of our students’ discourse demonstrates how their use of interpretive repertoires locks them in belief talk that they have no control over ecological issues, which can put them in the danger of falling prey to ecological passivity. As a consequence of our findings we suggest that teachers should be endorsed to interpret their teaching of environmental issues in terms of the enriching and enlarging of their students’ interpretive repertoires.  相似文献

Policy around the legal status and social rights of the nation’s estimated 11 million undocumented immigrants is unresolved, making it imperative that PK-12 schools and educators prepare for challenges to undocumented students’ educational access. In 2008, Immigration and Customs Enforcement (ICE) appeared near an elementary school, which required school personnel to use the space in and around their school to demarcate boundaries to limit the impact of ICE activity on the school community. Critical moral geography is the guiding theoretical construct the authors use to examine the intersection of immigration policy and education in the context of immigration enforcement near a public school. Critical moral theory suggests that “places” are sites where people contest their values and concepts of what is morally correct, engaging in struggles over power. Thinking about space broadly allows for an exploration of how different policies converge and affect the spaces where educators are trying to engage in moral work. The authors conclude that educators can be instrumental in creating safe spaces for undocumented students.  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

In this article, the author argues that there is still much to learn from the moral theories developed by two eminent philosophers, John Smith and David Hume, that can contribute to enhancing the sensibilities of students in classroom discussions about a range of moral and social justice issues. He argues that when school students are afforded the opportunity to imagine the circumstances of those persons suffering various forms of social marginalization, they can gain a heightened awareness on the affective and practical implications of social injustice, and feel more compelled to transform the unacceptable inequities they encounter. He suggests that encouraging students to use their moral imaginations and sensibilities will invoke a sympathetic response that raises their collective consciousness on the moral importance of attempting to create a more compassionate, benevolent and equitable society.  相似文献

Abstract

Prior research estimating the effect of Catholic schooling has focused on high school, where evidence suggests a positive effect of Catholic versus public schooling. In this article, we estimate the effect of attending a Catholic elementary school rather than a public school on the math and reading skills of children in kindergarten through fifth grade. We use nationally representative data and a set of matching estimators to estimate the average effect of Catholic schooling and the extent to which the effect varies across educational markets. When we use public school students nationwide or within the same county to provide a counterfactual estimate of how Catholic school students would have performed in public schools, we find strong evidence indicating that Catholic elementary schools are less successful at teaching math skills than public schools (Catholic school students are 3–4 months behind public school students by third and fifth grade), but no more or less successful at teaching reading skills. Moreover, unlike prior research, we find no consistent evidence that the effects of Catholic schooling vary substantially by race or urbanicity, though our power to detect such differences is weak.  相似文献

While much empirical research concerns job tenure, this paper introduces the concept of school tenure and further examines whether and how school tenure impacts student outcomes using a rich set of cohort data from England’s secondary schools. Using the number of times a student switched schools during the academic year as an instrument to measure school tenure to fully account for endogeneity issues, the resulting two-stage least squares estimates suggest that the effects of school tenure are positive and heterogeneous across students. While advantaged students are more likely to gain when their own school tenure is longer, disadvantaged students benefit if their peers have longer tenure. This significant heterogeneous effect suggests that school tenure may not simply act as the inverse of school mobility but may represent a potential determinant of student achievement and an effective school-specific measure for policymakers and practitioners. The relevant implications are accordingly discussed.  相似文献

This study investigated the relationship among 68 high school students’ scientific epistemological beliefs (SEBs), cognitive structures regarding nuclear power usage, and their informal reasoning regarding this issue. Moreover, the ability of students’ SEBs as well as their cognitive structures for predicting their informal reasoning regarding this issue was also examined. The participants’ SEBs were assessed with a quantitative instrument; their cognitive structures were assessed through tape‐recorded interviews and were further analyzed with the ‘flow map method’; their reasoning regarding nuclear power usage was assessed with an open‐ended questionnaire; and, then, their responses were analyzed both qualitatively and quantitatively. It was revealed that students’ beliefs about the justification of scientific knowledge (an aspect of the beliefs on the nature of knowing science) were significantly correlated with their reasoning quality; the extent and the richness of students’ cognitive structures as well as their usage of the information processing mode, ‘comparing,’ were positively correlated with their reasoning quality. A series of regression analyses further confirmed that students’ use of the information processing mode, ‘comparing,’ was the most significant factor for predicting reasoning quality, while their beliefs regarding the justification of scientific knowledge was the other important predictor.  相似文献

This paper reports on degrees of awareness and use of specific metacognitive strategies by 16 students in a final-year high school biology class in New Zealand. The aims of the intervention were to broaden students' thinking about bioethical issues associated with cancer and to enhance students' use of metacognition. Cues and prompts were used in this unit of work to help students use metacognitive strategies since students did not generally use metacognitive strategies spontaneously. Scaffolding was mediated through the teacher modelling, questioning, cueing or prompting students to evaluate their learning. The research reported here illustrates how teachers can cue students to be more self-directed in their learning. Three case studies illustrate how learning strategies were used differentially. Most students were aware of strategies that could help them to learn more effectively. It was found that those students who were not only aware of but also used strategies to plan, monitor and evaluate their work, produced essays of higher quality.  相似文献

A case study is reported involving 32 applied and academic program student volunteers aged 15–18 years from two high schools located in Northern Ontario, Canada. Students were interviewed regarding a number of educational policy and school climate issues. The study examines perceptions of rights as an aspect of the school learning environment. The need for greater school community and additional supports for struggling students was voiced by students across both program groups. Students strongly endorsed either a meritocratic or an equalitarian perspective on rights issues with both philosophies represented to some extent in both program groups. Surprisingly, students across both program groups expressed little interest in their education rights or their legal rights generally. The importance of fostering school community and student interest in rights issues is discussed. Also considered is the role of the social science researcher in providing youth a forum for the discussion of social policy issues.  相似文献

This study investigates how the use of calculators during high school mathematics courses is associated with student performance in introductory college calculus courses in the USA. Data were drawn from a nationally representative sample of 7087 students enrolled in college calculus at 134 colleges and universities. They included information about students’ demographics, standardized test scores, and high school mathematics course enrollment and performance. Factor analysis reduced ten items describing high school calculator usage to two composites: how extensively calculators were employed and teacher-imposed restrictions on their use. Hierarchical linear models predicted students’ college calculus grades, reported by their professor, while controlling for differences between colleges and student backgrounds. The more extensively students had used calculators in high school, the lower their grade in college calculus. However, students earned higher college calculus grades to the extent that their high school teachers had limited calculator use on quizzes and exams and had restricted calculator use until paper-and-pencil methods had been mastered, which offset the negative association of extensive calculator use with grades. The effect sizes of both calculator composites were very small. Overall, the findings raise doubts about any substantial long-term effects on college mathematics performance of calculator use in high school.  相似文献

Abstract

This article is based on a year‐long study of elementary to secondary transition in rural Ontario, Canada. The study considered the experience of transition for rural students within the political context of recently mandated changes to the transition years in Ontario. Research elsewhere suggests that the strong academic orientation of the secondary school creates a polarized and fragmented school culture which leads to student alienation and high drop‐out rates. These issues were regarded as less relevant in the rural area where the study took place and, thus, the teachers, parents and students who participated were sceptical about the need for change. The article examines the influence of contextual factors, including the rural setting, school structure and size, and teacher experience, on school culture and curriculum, and participants’ experiences of transition and their perspectives on change. A dialogical approach to enquiry was taken which attempted to bring together, through dialogue, the disparate views of research and participants to achieve new understandings on the critical issues of rural transition.  相似文献

Drawing on participant-observation research conducted in one core urban and one affluent suburban public school, the author argues that critical educational theorists should devote more attention to differential structural constraints on pedagogic choice. Teachers at the urban North End Community School make pedagogic choices that reinforce social hierarchies. They do so, in part, in order to enable their students to manage a series of risks and dangers associated with concentrated urban poverty. The evidence presented suggests that changing the role power plays in urban public schooling requires changing not only the choices individual teachers make, but also educational and other institutional constraints on pedagogic practice.  相似文献

Working with scientists has been suggested as an effective way for high-school students to learn authentic science. However, little research has involved students’ perceptions of science learning environments in a university internship. This study drew on the theoretical framework of community of practice with cogenerative dialogues to design an internship program that aims to build a constructivist internship for students. Students who learned science in the internship program developed stronger constructivist learning perceptions than those who learned science in school. Specifically, students perceived that they had more opportunities to think independently of the instructors and other students. Three effective principles for program design are: (a) high school students conduct open-inquiry projects with the support of scientists; (b) high school students and scientists conduct cogenerative dialogues regularly to address issues and share experiences; and (c) high school students present their project proposals and scientific findings at open house events. Implications of the results are discussed.  相似文献

In this study, we administered a questionnaire to 1001 vocational high school students to ascertain their literacy with regard to energy saving and carbon-emissions reduction (ESCER) and to analyze whether their literacy was affected by their gender or academic major. The data analysis produced the following conclusions: (1) behaviors pertaining to ESCER among vocational high school students should be enhanced by promoting appropriate affect rather than solely by conveying knowledge; (2) female students displayed superior knowledge and affect regarding ESCER compared with male students; and (3) students majoring in agriculture performed better than other students in terms of knowledge, affect, and behavioral aspects related to ESCER. The execution and results of this study can serve as a reference for courses or education related to this topic targeting vocational high school students to promote literacy for ESCER, thereby increasing students’ effectiveness in related issues in Taiwan.  相似文献

Full-time virtual schooling is a growing alternative to traditional schools, although it is an option still unknown to many students. The ability to inform students through marketing is thus foundational to the success of virtual schools. Using a qualitative case study methodology, this article examines marketing patterns for nonprofit virtual schools, including how students find out about virtual schools; the ways in which school leaders market their schools; and changes reported in schools’ marketing and recruitment needs and strategies. This analysis suggests that students find out about virtual schools in many ways, including being referred, rejected, and urged by their local schools. Implications include issues around socioeconomic equity, especially in terms of school access, funding, and educational quality.  相似文献
