This paper provides an analysis of a teaching episode of the multidigit algorithm for multiplication, with a focus on the influence of the teacher’s mathematical knowledge on their teaching. The theoretical framework uses Mathematical Knowledge for Teaching, mathematical pertinence of the teacher and structuration of the milieu in a descending and ascending a priori analysis and an a posteriori analysis. This analysis shows a development of different didactical situations and some links between mathematical knowledge and pertinence. In the conclusion, the contribution of the frameworks from both French and Anglo-American origins is briefly addressed.  相似文献

The purpose of this article is to provide an overview of how the employees of higher education institutions perceive the impact of external evaluations. The study was conducted using the concurrent mixed method and involved 361 employees from Estonian universities and professional higher education institutions. The results indicated that evaluation is mostly deemed necessary at the levels of the organisation and the system; from the personal viewpoint of an employee, positive effects of external evaluations are perceived to a lesser degree. The negative influences mentioned were increased bureaucracy, extra work and stress. Top managers of institutions most often saw the positive influences from external evaluations since they help to implement reorganisations and development activities within an organisation. Managers perceived the positive effects of external evaluations on their everyday work as well, more than other employees did. Researchers felt the positive effects of external evaluations least. Nearly a quarter of all employees of higher education institutions do not perceive the effects of external evaluations on their everyday work at all. Employees of professional higher education institutions perceive the positive effects of external evaluations to a greater extent than employees of universities do, indicating that external evaluation has contributed to the development of their organisations. The differences in opinions of the employees of higher education institutions regarding perceived positive and negative impacts of external evaluations—whether on individual, organisation or system points of view—indicate that employees do not identify closely enough with the organisation and its strategic goals.  相似文献

The purpose of this study is to examine the effects of assessment method (essays vs. examinations) and instruction method (seminars vs. lectures) on student perceptions of the fairness of the assessment process. Department-specific combinations of these factors give a unique profile to the assessment process and to the way students interact with faculty. It is argued that the conditions thus created place students in some departments in a more advantageous position when it comes to meeting justice-related expectations. The variables of interest are procedural justice (PJ) and informational justice (IJ). For PJ, aspects regarding the amount of control students can exert on the grading process (PJ-C) are distinguished from aspects regarding the perceived validity of grading procedures (PJ-V). The sample consists of 1549 students from 48 departments of a German university. Analysis is done via multilevel mixed effects models. Models also check for cross-level interactions between effects of the academic environment and student socioeconomic status (SES). Results show that PJ-C and PJ-V are significantly affected by the assessment method. Higher proportions of essays relative to examinations in a department lead to higher ratings of PJ-C, while they decrease ratings of PJ-V. Ratings of IJ are higher as well if assessment is more essay-based, although this only affects low-SES students. Regarding the instruction method, a higher proportion of seminars was found to significantly increase PJ-C and IJ. Again, effects on IJ are moderated by parental SES. Policy implications for reducing feelings of injustice are discussed.  相似文献

We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains.  相似文献

Rubrics are assessment tools that help students gain complex competencies. Our quasi-experimental study aimed to evaluate whether rubrics help teachers teach and assess mathematical reasoning in primary school and whether such an instrument might support student learning. In two Swiss cantons, 762 students in 44 5th- and 6th-grade primary classes worked on their reasoning competencies, and half of them additionally employed our standards-based rubric. All of the teachers received a 1-day training and participated in the final project evaluation. To standardise and support the teachers during the implementation phase, they received a detailed curriculum. An achievement test and questionnaires for students and teachers were administered before and at the end of the intervention. The results of our quantitative longitudinal analyses indicate that the rubric fosters the teachers’ perceived diagnostic skills but only indirectly impacts their use of formative feedback. Based on the students’ perceptions, however, we observed a direct effect of the rubric on formative feedback and student self-assessment. Effects on students’ outcomes could not be observed, but there are indications of effects mediated by self-regulation and self-efficacy.  相似文献

Educational research often portrays culturally, linguistically and economically disenfranchised (CLED) children’s disengagement from school learning as individual behaviour, ignoring the contribution of race, gender, socio-cultural, ethnic and social class factors. This paper analyses a specific community engagement programme in Australia which uses experiential learning in an informal setting. The programme, which has been running for seven years, partners pre-service teachers, volunteer high school students and volunteers from a national bank with primary schools where many pupils are experiencing learning difficulties and school engagement problems as a result of their socio-economic status, their poverty, and their ethnic and cultural diversity. Drawing on the perspectives of the children and volunteers participating in the pilot study, and privileging their voices, this paper illustrates how community partnerships may be developed and sustained. The programme’s conceptual framework of Connecting-Owning-Responding-Empowering (CORE) pedagogy is explored for its potential to enhance student engagement, achievement and empowerment through focused community involvement. The findings show that when students feel connected to and involved in their community, all participants are empowered in their learning and teaching.  相似文献

With societal changes rapidly transforming cultures that had been largely homogenous, today’s multi-cultural – and in particular interfaith – families need new educational strategies to help them understand their cultural roots and identify and clarify what aspects of their heritages they wish to nurture and transmit to their children. This paper focuses on a new model for religious education, namely non-doctrinaire “dual-faith” education, which the principal author has helped to develop in the United States (US) through the Interfaith Community (IFC), a small, independent non-profit organisation created and led by dual-faith Jewish/Christian families. The model is premised on the notion that families can have two different faiths in one household and that – with respect and education – families can be harmonious, religion can be transmitted, and tolerance broadly nurtured. While the model is particular to the US and to families with Jewish and Christian heritages, its premises and structure have significant potential to be adaptable to other religious combinations and other cultures and countries. After reviewing relevant literature and situating the IFC model in the global and US contexts, the paper sets out to clarify the importance of the concept, describe its elements, and discuss its implications for religious education in this time of changing ethos and demography.  相似文献

This article presents the results of a textual analysis conducted on policy discourses on international students in the UK between 1999 and 2013. A number of rationales for and against increasing their numbers have been made, which have largely remained consistent over changing political administrations. One key rationale is that international students enhance the UK’s global political influence through its soft power. Critical analysis indicates that a number of unsubstantiated assumptions are made, representing international higher education and students in an outdated power relation predicated on Cold War politics. Key assumptions are that international students change their political attitudes and identify with the host country as a result of positive experiences. Later they are supposed to return home and reach positions of influence, which they exert in favour of the UK. They are represented to feel the same whether on scholarship or self-funded; and behave in predictable, similar ways. These representations of students as social subjects have disciplinary implications, which should be a topic for critical debate and potentially resistance in pedagogical contexts.  相似文献

This study analyses the university choices of male and female students in Italy over the 2003–2012 period and for two sub-periods before (2003–2008) and after (2009–2012) the 2008 financial crisis. The analysis is guided by human capital, signalling and preference theories and implemented through a competing destinations model that controls for the socio-economic features of both the region of origin and destination. The findings show that in the post-crisis period, males became more career-oriented in their university choices due to increasingly constrained and competitive labour markets. The constrained post-crisis labour markets led females to focus more on the educational experience than on future employability prospects. Our results suggest that the financial crisis maintained or even widened gendered social roles as they relate to university choices; specifically, males assumed an even greater career-centred family role, whereas females adopted more adaptive lifestyles that potentially place them at a disadvantage in the labour market and in society in years to come.  相似文献

In the past few decades, the additional revenues available via higher education exports (through both relatively higher prices and increased enrolments) have attracted the attention of providers in many developed countries, not least in Anglophone countries like the USA, the UK, Canada and Australia. However, while the revenue case is strong, the institutional cost structures underlying the provision of higher education services for international students remain relatively unknown at the sector level. Accordingly, we offer a comprehensive analysis of the cost economies underlying higher education provision for international students using a sample of 37 Australian public universities over the period from 2003 to 2012. The findings suggest that it is appealing to enrol additional overseas students given their lower average and marginal costs and the significant economies of scale prevailing in higher education generally. Further, while we find evidence of economies of scope for overseas students only in smaller institutions, there is no evidence of diseconomies of scope, implying the current number of overseas students and their joint production with domestic students at the least does not lead to unnecessarily higher overall costs.  相似文献
