This paper presents some results of a qualitative study carried out in a secondary school in the city of Buenos Aires (Argentina). It examines how two students from poor families responded to, and viewed, aggression by peers at their school. This paper argues that the examination of students’ narratives about aggression (based on classism and sexism) illustrates the analytical usefulness of the moral dimension of social life to unpack crucial aspects of the micro politics of class and gender and processes of identity-making. Following Sayer, this article maps students’ responses to immoral sentiments and misrecognition: the search for respect and respectability, and moral boundary drawing. It demonstrates that these reactions are entangled in students’ class and gender identity-making. It also shows how ‘victims’ are able to regain respect. However, the individualized nature of these processes and the spirals of aggression they instigate demonstrate the fragile and temporary nature of this achievement. 相似文献

This paper investigates the noticing of six Chinese mathematics prospective teachers (PSTs) when looking at a procedural error and responding to three specific tasks related to that error. Using video clips of one student’s procedural error consisting of exchanging the order of coordinates when applying the distance formula, some variation was found in how PSTs attended to, interpreted, and responded to this error. A more important finding is represented by the inconsistent responses that individual PSTs provided to the three related tasks. This finding suggests that, to some extent, prior learning experience, beliefs, and orientations inform what PSTs notice. But the finding also suggests the centrality of selecting tasks that provide accurate representations of PSTs’ emerging professional noticing. Implications for teacher educators are discussed. 相似文献

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated. 相似文献

Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view
of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called
chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks
in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which
scientific change is assimilated by their writers.

县级中学高中生物理考试成败归因特点 总被引:1,自引:0,他引:1
以435名县级中学高中生为被试,以考试成败归因问卷为工具,旨在探讨高中生对物理考试成败结果的归因特点。研究表明:(1)整体上看,县级中学高中生对物理考试成败倾向于作内部归因,他们将持久努力、临时努力和学习方法等内部可控原因视为首要原因;(2)自我评价成功者与失败者对考试结果的归因存在明显差异;(3)男女生对考试成功的归因不存在明显的差异,对考试失败的归因有一定差异,女生比男生更看重能力、学习方法、学习基础与任务难度等原因对失败结果的影响;(4)高中生对考试成败的归因不存在明显的年级差异。 相似文献

Purpose
Preschooler instruction for speech sound awareness typically teaches a progression of speech units from sentences to phonemes, ending at simple first phoneme activities. This study investigates the effects of teaching advanced tasks of phoneme blending and segmenting with and without the larger speech unit of the syllable.Method
Thirty-nine 4-5-year-old typically developing children received twice-weekly small-group instruction in three conditions: two weeks of syllable tasks then four weeks of multiple phoneme tasks (SP), four weeks of multiple phoneme tasks only (MP), or an active control condition of first phoneme instruction (FP).Results
The conditions SP and MP showed large significant gains on blending and segmenting and no significant differences on first phoneme isolating compared to the FP condition. A comparison of SP and MP did not show significant differences on phoneme blending and segmenting, but SP showed significantly more confusion during early sessions of phoneme instruction.Conclusion
This preliminary evidence suggests that preschoolers can improve understanding of phoneme blending and segmenting, without first being taught syllable blending and segmenting, and with no negative effects on first sound awareness. These findings support a more efficient way of teaching preschoolers awareness of the individual sounds of speech. Replication with a larger sample, including children at-risk for literacy difficulties, is recommended before firm conclusions should be drawn. 相似文献88.
The need for supporting student writing has received much attention in writing research. One specific type of support is feedback—including peer feedback—on the writing process. Despite the wealth of literature on both feedback and academic writing, there is little empirical evidence on what type of feedback best promotes writing in online environments. This article reports on research that tries to determine what type of feedback best improves the quality of collaborative writing and what the effects of feedback are on student learning in an environment based on asynchronous written communication. The results reveal that concerning the type of feedback, epistemic feedback or epistemic and suggestive feedback best improve the quality of collaborative writing performance. The nature of the feedback-giver (whether teacher feedback or teacher and peer) makes a difference to the final text only when the feedback is epistemic, or epistemic and suggestive. 相似文献

In 2011 we, a group of English-as-a-foreign-language teachers at a secondary school in Argentina, decided to investigate our teaching practices through collaborative action research so as to improve our students’ learning opportunities and thus revitalise English-language teaching in our context. We implemented and evaluated the integration of content and language learning in our classrooms through the development of our own materials. The experience revealed a growth in professional development and how our motivation and autonomy influenced our students’ motivation and language development. In our attempt to disseminate our experience as a group, this report particularly focuses on the evaluation facets of our collaborative action research project so as to encourage other teachers and teacher-researchers to adopt collaborative action research to improve their own practices. 相似文献

The aim of this research is to identify the difficulties experienced by secondary school students (aged 15–16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties ‘Elements of science critical reading’ were identified on the basis of the ‘Elements of reasoning’ of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results. 相似文献
