Teacher educators’ collaboration plays an important role in the improvement of teacher education. Many studies in educational research focus on collaboration from 1 particular perspective. A focus on 2 perspectives, a qualitative (focusing on collaborative activities) as well as a quantitative (focusing on relations) perspective, and relating both perspectives, can add to our knowledge. Data were collected in 3 subject departments of a teacher education institute. Findings indicated that educators’ collaborative networks inside the departments could gain from more coherent and dense relations, and that key players were important to support and sustain collaboration. Both perspectives were mildly related, correlations were found for “degree” and “information” (r = .31, p < .05), “degree” and “joint work” (r = .38, p < .01), and “reciprocity” and “joint work” (r = .33, p < .05), no correlations were found for “degree” or “reciprocity” and “discussing”. At the department level, only mathematics showed significant correlations. Results indicated that, in further research, qualitative aspects as well as quantitative aspects should be included. 相似文献

This paper reports on a qualitative study that examined how pair programming shapes the experience of secondary school girls taking IT as a subject, with respect to their enjoyment of programming and the subject itself. The study involved six Grade 11 girls who were doing solo programming in Grade 10 and pair programming in their following Grade. The results showed that the girls enjoyed the subject more when programming in pairs due to improved comprehension of the task. They especially enjoyed the socialization and communication brought about by pair programming. The assistance, support, motivation, focus and encouragement they received from partners when stuck or while fixing errors made the programming experience more enjoyable for them. The increased enjoyment brought about by pair programming resulted in the perception of greater learning in the subject IT and also to greater interest in it. It also led to greater persistence in dealing with problems. Pair programming should be implemented right from the start of Grade 10 since it may lead to greater enjoyment of programming and the subject IT in general. The approach may also lead to more girls being attracted to the subject. 相似文献

This paper draws on semi‐structured interview data and participant observations of senior secondary Physical Education (PE) teachers and students at two school sites across 20 weeks of the school year. The data indicated that the teachers in this study made progressive judgements about students’ level of achievement across each unit of work without explicit or overt reference to the criteria and standards represented in the schools’ work programmes and in the Senior PE syllabus. The teachers’ justification for such an approach was that the criteria and standards had become for them sufficiently ‘internalised’. Determining students’ levels of achievement was for the teachers somewhat ‘intuitive’, being reliant on their memory of students’ performances, and influenced by the construct‐irrelevant affective characteristics of the students. It is argued in this paper that such construct‐irrelevance compromised the construct validity and possible inter‐rater reliability of the decisions made and advantaged some students and marginalised others on the basis of characteristics that were not specifically related to the learning expected from following the syllabus. The potential inequities of such an approach are discussed and suggestions are made for the consolidation of the validity and reliability of teachers’ judgements. 相似文献

This paper describes a case study focusing on the subject matter knowledge, pedagogical content knowledge, and beliefs about science teaching of student teachers in Turkey at the start of their university education. The topic of interest was that of teaching chemical reactions in secondary chemistry education. A written test was developed which used the research literature on potential student misconceptions with regard to different aspects of chemical reactions. Thirty beginning science student teachers were tested, with an additional eight interviews from the student teachers in the same sample. The interviews focused on student teachers’ views about how to best teach chemical reactions in lower secondary chemistry classes. The results revealed deficits in the subject matter knowledge of the student teachers. It also became obvious that the teachers in this sample held very traditional and teacher-centred beliefs when it came to chemistry teaching at the secondary level. Their teaching attitudes were geared mainly towards the acquisition of facts by pupils, and often ignored the development of process-oriented skills. Implications for science teacher education are discussed. 相似文献

In Europe, national quality assurance systems of higher education have begun to be established. In Finland, this development has had the consequence of forcing universities to take notice of assessment procedures. However, little is known about the procedures taking place in individual academic departments as a result of this pan‐European trend. This article describes how academics currently comprehend quality assessment, paying particular attention to self‐evaluations and quality assurance systems. Altogether, the paper casts light on how academics are responding to the increasing university assessment activities. 相似文献

Viewing science education as a site of biopolitical engagement—intervention into forces that seek to define, control, and exploit life (biopower)—requires that science educators ask after how individuals and populations are governed by technologies of power. In this paper, I argue that microanalyses, the analysis of everyday practices and discourses, are integral to biopolitical engagement, are needed to examine practices that constitute subjectivities and maintain oppressive social conditions. As an example of a microanalysis I will discuss how repetitive close-ended lab/assessment tasks, as well as discourses surrounding careers in science, can work to constitute students as depoliticized, self-investing subjects of human capital. I also explore the relationship between science education, (bio)labor and its relation to biopolitics, which remains an underdeveloped area of science education. This paper, part of my doctoral work, began to take shape in 2011, shortly after the 2008 economic crisis achieved a tiny breached in the thick neoliberal stupor of everyday (educational) life. 相似文献

Knowing the subject matter of a secondary‐school science subject 总被引：1，自引：1，他引：0

This paper examines the fundamental yet largely neglected distinction between school subjects and academic disciplines in the discourse on teachers’ specialized subject‐matter knowledge. It analyses and critiques the curricular positions embedded in that discourse in the light of five possible relationships between school subjects and academic disciplines. Invoking Dewey’s logical‐psychological distinction and research findings, the paper argues that the subject matter of a secondary‐school science subject instead of the subject matter of its parent academic discipline lies at the heart of secondary‐school science teachers’ specialized subject‐matter knowledge. Knowing such subject matter entails knowing five intersecting dimensions: the logical, the psychological, the pedagogical, the epistemological, and the sociocultural. Implications are drawn concerning theorizing about what secondary‐school science teachers need to know about the subject matter they are expected to teach, subject‐matter preparation for teaching, and the development of secondary‐school science curriculum materials. 相似文献

This study examined the validity of students’ evaluations of teaching as an instrument for measuring teaching quality by examining the effects of likability and prior subject interest as potential biasing effects, measured at the beginning of the course and at the time of evaluation. University students (N = 260) evaluated psychology courses in one semester at a German university with a standardized questionnaire, yielding 517 data points. Cross-classified multilevel analyses revealed fixed effects of likability at both times of measurement and fixed effects of prior subject interest measured at the beginning of the course. Likability seems to exert a substantial bias on student evaluations of teaching, albeit one that is overestimated when measured at the time of evaluation. In contrast, prior subject interest seems to introduce a weak bias. Considering that likability bears no conceptual relationship to teaching quality, these findings point to a compromised validity of students’ evaluations of teaching. 相似文献

Based on qualitative data gathered in one Finnishuniversity, the article examines disciplinary culturesof four study fields: computer science, libraryscience and informatics, public administration, andsociology and social psychology. It is suggested thatthe core of each discipline can be conceptualized asa moral order that defines the basic beliefs, valuesand norms of the local culture. Following this frameof reference, the analysis of students' accountsdemonstrates essential differences regarding how thevirtues and vices of studying are understood and whatkinds of social identities are constructed indifferent fields. The implications of the results forthe quality assessment and the development ofuniversity teaching are discussed. 相似文献

This paper asks why spatially separated school departments might exhibit, in different ways, very similar practices. Data from an ethnographic study of three secondary school geography departments in England are discussed through a concept of ‘isomorphism’ (homogenising forces), drawn from neo-institutional theory. Similarities across these departments are analysed in terms of coercive isomorphism, including the strong regulatory role played by examination boards and Ofsted; mimetic isomorphism, in which similar approaches are adopted in response to situations of high uncertainty, based on spreading good practice; and normative isomorphism, including the implications of closely guarded educational routes, the professionalisation of teaching, and wider social trends including the increasing use of Google as a source of knowledge for lessons. It is argued that evidence of homogeneity across spatially separated departments raises interesting questions about teachers’ practice, with implications for departmental and school leadership. 相似文献

Curriculum reforms with a focus on helping students ‘learn to learn’ are now an established global educational phenomenon. China has been implementing such curriculum reform and this poses challenges to teachers as they need to develop new pedagogical skills and knowledge to deal with new educational demands that arise. This ethnographic study investigates the impacts of current curriculum reform on teacher learning using two subject departments from two schools in Shanghai, China. It shows that teachers direct much attention towards searching for good practices and norms of practice to encounter new curriculum challenges. Findings show that outside experts who act as ‘boundary brokers’ are crucial in teacher learning. They also identify two modes of teacher learning activities: hierarchical, which relies on imported expert knowledge; and reciprocal, which depends on exploiting local knowledge. Striking a balance between these two approaches may be the way forward. 相似文献

The objective of the present study was to compare the toxicity and availability of Fe(Ⅱ) and Fe(Ⅲ) to Caco-2 cells.Cellular damage was studied by measuring cell proliferation and lactate dehydrogenase (LDH) release. The activities of two major antioxidative enzymes [superoxide dismutase (SOD) and glutathione peroxidase (GPx)] and differentiation marker (alkaline phosphatase) were determined after the cells were exposed to different levels of iron salts. The cellular iron concentration was investigated to evaluate iron bioavailability. The results show that iron uptake of the cells treated with Fe(Ⅱ) is significantly higher than that of the cells treated with Fe(Ⅲ) (P＜0.05). Fe(Ⅱ) at a concentration>1.5 mmol/L was found to be more effective in reducing cellular viability than Fe(Ⅲ). LDH release investigation suggests that Fe(Ⅱ) can reduce stability of the cell membrane. The activities of SOD and GPx of the cells treated with Fe(Ⅱ) were higher than those of the cells treated with Fe(Ⅲ), although both of them increased with raising iron supply levels. The results indicate that both Fe(Ⅱ) and Fe(Ⅲ) could reduce the cellular antioxidase gene expression at high levels. 相似文献

A substantial body of research emphasises school leadership as a major influence on quality improvement in schools. Although numerous studies have identified the importance of the principal, fewer studies have examined the middle management level within schools, the deputy heads and assistant principals. Influenced by international trends, local education authorities in Norway have reorganised a traditional administrative deputy head role into a new role with expanded leadership responsibility for teacher staff and for performing instructional leadership. The primary objective of the present qualitative study is to provide additional insight into how deputy heads make sense of increased responsibility and power distribution as members of the leadership team and as leaders of the teachers in lower secondary schools. Drawing on focus group interviews and observations, the findings show that the reorganisation may open for a change from traditional administrative roles towards becoming learning-focused leaders. However, the findings also indicate that the shift can produce tensions between autonomy and control for the new leader role in the middle. 相似文献

This paper reports the main findings of a study that sought to understand how teachers and department heads perceived and experienced the implementation of a classroom observation system in a teacher evaluation context. The data was collected through a teacher and department head survey and interviews with department heads who were responsible for classroom observation. The findings show that respondents regarded classroom observation as an inadequate teacher evaluation instrument. It was also viewed as one of the features of the teacher evaluation system that least contributed to the teachers’ professional development. Department heads felt torn between their intermediate management role as teacher observers and their professional role as teacher peers. Cultural norms of individual professional autonomy that regulated relations among colleagues prevented department heads from using information, gathered through classroom observation, to nourish in-depth professional discussions about concrete educational practices. 相似文献

Seismic ductility of very-high-strength-concrete short columns subject to combined axial loading and cyclic lateral loading 总被引：1，自引：0，他引：1

The seismic ductility of reinforced very-high-strength-concrete (VHSC) short columns was studied by combinatively applying axial load and low cyclic lateral load on specimens to simulate seismic impact. Twelve specimens with concrete compressive strength ranging from 95.6 MPa to 118.6 MPa and a shear-span ratio of 2.0 were tested for shear failure pattern and fear force-displacement hysteretic responses. Combinative application of axial load and low cyclic lateral load to VHSC short columns incurs shear failure. The displacement ductility is much smaller when the axial load ratio is larger;whereas a larger stirrup ratio is accompanied with a better displacement ductility. The relationship of displacement ductility factor, μ?, with stirrup characteristic value, λv, and test axial load ratio, nt, is μ?=(1 8λv)/(0.33 nt). By this relationship and relevant codes for aseismatic design, the axial load ratio limits for aseismatic design of reinforced VHSC (C95 to C100) short columns for frame construction are respectively 0.5, 0.6, and 0.7 for seismic classes I, II, and Ⅲ;corresponding minimum characteristic values of stirrups are calculated according to the required characteristic values of at least 1.273 times of experimental results. These data are very useful to aseismatic engineering. 相似文献

Background: Feedback is one of the most significant factors for students’ development of writing skills. For feedback to be successful, however, students and teachers need a common language – a meta-language – for discussing texts. Not least because in science education such a meta-language might contribute to improve writing training and feedback-giving.
Purpose: The aim of this study was to explore students’ perception of teachers’ feedback given on their texts in two genres, and to suggest how writing training and feedback-giving could become more efficient.
Sample: In this study were included 44 degree project students in biology and molecular biology, and 21 supervising teachers at a Swedish university.
Design and methods: The study concerned students’ writing about their degree projects in two genres: scientific writing and popular science writing. The data consisted of documented teacher feedback on the students’ popular science texts. It also included students’ and teachers’ answers to questionnaires about writing and feedback. All data were collected during the spring of 2012. Teachers’ feedback, actual and recalled – by students and teachers, respectively – was analysed and compared using the so-called Canons of rhetoric.
Results: While the teachers recalled the given feedback as mainly positive, most students recalled only negative feedback. According to the teachers, suggested improvements concerned firstly the content, and secondly the structure of the text. In contrast, the students mentioned language style first, followed by content.
Conclusions: The disagreement between students and teachers regarding how and what feedback was given on the students texts confirm the need of improved strategies for writing training and feedback-giving in science education. We suggest that the rhetorical meta-language might play a crucial role in overcoming the difficulties observed in this study. We also discuss how training of writing skills may contribute to students’ understanding of their subject matter. 相似文献

Science teachers need to understand the subject matter they teach. While subject matter knowledge (SMK) can improve with classroom teaching experience, it is problematic that many secondary science teachers leave the profession before garnering extensive classroom experience. Furthermore, many new science teachers are assigned to teach science subjects for which they do not hold a degree. This study investigates the SMK of new secondary science teachers assigned to teach chemistry in their first three years of teaching. These new teachers do not have the advantage of years of experience to develop their SMK and half hold a degree in biology rather than chemistry. This qualitative study explores the effects of holding a degree in the subject area one teaches as well as classroom teaching experience on teachers’ SMK for two chemistry topics, conservation of mass and chemical equilibrium. Qualitative analysis of semi-structured interviews indicated that the SMK of teachers who had a chemistry degree and more extensive classroom experience was more coherent, chemistry-focused, and sophisticated than that of teachers who lacked this preparation and experience. This study provides evidence that new science teachers’ SMK is influenced by both holding a degree in the subject area and having classroom experience. 相似文献
