This article arises from a study whose overall purpose was to investigate the relationship between Colombian mathematics teachers’ conceptions of beginning algebra and their conceptions of their own teaching practices. The teachers’ understandings of their teaching practices were explored with a view to unravelling their conceptions of change in their teaching. Focusing on the perspectives of teachers afforded opportunities that exposed the powerful role that the teachers’ conceptions of social/institutional factors of teaching played in their conceptions of their practices. The degree to which the teachers attributed these (external) factors as crucial reasons for what they do in their teaching was the basis of a categorisation of their conceptions of the crucial determinants of their teaching practices into three types. The findings are particularly relevant to our understanding of the stability of mathematics teaching approaches in the Colombian context but have likely implications for a range of international education contexts. Specific implications for the development of the research into teachers’ conceptions of mathematics and its teaching, and for teacher education programmes are presented.

Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the Introductory Biology I class is associated with even more dramatic gains among students from underrepresented minority populations than the gains found among their peers. These gains do not seem to be the product of better students availing themselves of supplemental instruction or other outside factors. The Introductory Biology I class consists of a team-taught lecture component, taught in a large lecture classroom, and a laboratory component where students participate in smaller lab sections. Students are expected to master an understanding of basic concepts, content, and vocabulary in biology as well as gain laboratory investigation skills and experience applying scientific methodology. In this context, supplemental instruction classes are cooperative learning environments where students participate in learning activities that complement the course material, focusing on student misconceptions and difficulties, construction of a scaffolded knowledge base, applications involving problem solving, and articulation of constructs with peers.  相似文献

OBJECTIVES: To examine the prevalence of bullying behavior in adolescents from Cape Town and Durban, South Africa, and the association of these behaviors with levels of violence and risk behavior. METHOD: Five thousand and seventy-four adolescent schoolchildren in grade 8 (mean age 14.2 years) and grade 11 (mean age 17.4 years) at 72 Government schools in Cape Town and Durban, South Africa completed self-report questionnaires on participation in bullying, violent, anti-social and risk behaviors. RESULTS: Over a third (36.3%) of students were involved in bullying behavior, 8.2% as bullies, 19.3% as victims and 8.7% as bully-victims (those that are both bullied and bully others). Male students were most at risk of both perpetration and victimization, with younger boys more vulnerable to victimization. Violent and anti-social behaviors were increased in bullies, victims and bully-victims compared to controls not involved in any bullying behavior (p<.01 in all cases). Risk taking behavior was elevated for bullies and bully-victims, but for victims was largely comparable to controls. Victims were less likely to smoke than controls (odds ratio .83, p<.05). Bully-victims showed largely comparable violent, anti-social and risk taking behavior profiles to bullies. Bully-victims showed comparable suicidal ideation and smoking profiles to victims. CONCLUSIONS: Results were in keeping with Western findings. Involvement in bullying is a common problem for young South Africans. Bullying behavior can act as an indicator of violent, anti-social and risk-taking behaviors.  相似文献

OBJECTIVE: Children who are physically maltreated are at risk of a range of adverse outcomes in childhood and adulthood, but some children who are maltreated manage to function well despite their history of adversity. Which individual, family, and neighborhood characteristics distinguish resilient from non-resilient maltreated children? Do children's individual strengths promote resilience even when children are exposed to multiple family and neighborhood stressors (cumulative stressors model)? METHODS: Data were from the Environmental Risk Longitudinal Study which describes a nationally representative sample of 1,116 twin pairs and their families. Families were home-visited when the twins were 5 and 7 years old, and teachers provided information about children's behavior at school. Interviewers rated the likelihood that children had been maltreated based on mothers' reports of harm to the child and child welfare involvement with the family. RESULTS: Resilient children were those who engaged in normative levels of antisocial behavior despite having been maltreated. Boys (but not girls) who had above-average intelligence and whose parents had relatively few symptoms of antisocial personality were more likely to be resilient versus non-resilient to maltreatment. Children whose parents had substance use problems and who lived in relatively high crime neighborhoods that were low on social cohesion and informal social control were less likely to be resilient versus non-resilient to maltreatment. Consistent with a cumulative stressors model of children's adaptation, individual strengths distinguished resilient from non-resilient children under conditions of low, but not high, family and neighborhood stress. CONCLUSION: These findings suggest that for children residing in multi-problem families, personal resources may not be sufficient to promote their adaptive functioning.  相似文献

Multi-academy trusts (MATs) are now a common feature of the English educational landscape. Yet numerous high-profile failures indicate that they present substantial challenges in terms of leadership and governance. One of the areas that most exercises school leaders and boards is the setting of strategic direction for the MAT. This includes elements such as its expansion. This article draws on 30 interviews with school leaders and trustees from 6 MATs and 10 interviews with national leaders of governance in looking to respond to the research question: What are the principal drivers for strategic expansion in MATs? The article begins by contextualising the research in light of recent policy, then moves to consider why theory on strategy as narrative was chosen in preference to other strategic approaches, and how it was employed to analyse data. The article concludes that within this sample there are a number of drivers for MAT expansion and that these fall under six principal categories: opportunities, values, pressures, feelings, risks and resources. It also concludes that resources and business viability play a substantial part in decisions to expand, and that strategy appears to be an iterative learning process. As such, it contributes to theory on the governance of multi-level organisations and to practice in terms of the Department for Education's focus on MAT growth.  相似文献

The role and number of Associate Dean posts in UK universities has grown considerably in recent years. Despite this, relatively little is known about the reasons why individuals take on such roles and how it fits into their career trajectories. The purpose of this article is to explore these issues by drawing on data from the first national study of Associate Deans in the UK. Adopting a two-staged mixed methods approach, data were collected from semi-structured interviews (n = 15) and an online survey (n = 172). The findings suggest that academics take on the role for a number of reasons such as the challenge of working across the University, making a difference to staff and students, or being asked to take it on by a senior member of staff. It is argued that these Associate Dean roles are part of new and emerging academic career pathways within the higher education sector.  相似文献

As they conduct the practical work of collaborating during meetings, nonprofit stakeholders construct, negotiate, and manage identities. In this article we use membership categorization analysis to explore how meeting participants avow and ascribe cultural identities during collaborative meetings in two nonprofit organizations. Examination of identification practices, including employing labels for ethnic categories and implicating cultural identities through category-relevant predicates—which are part of the practical work of collaborating in nonprofit organizations—can serve as an aid to understanding how stakeholders negotiate interorganizational collaboration in social interaction.  相似文献
