The pedagogical principle learning by research guides the current curriculum in agricultural high schools in Brazil. A problematization of the principle shows how (1) it feeds into current neoliberal and corporate agendas in the education sector, and (2) it associates mathematical formalism and abstraction as necessary conditions for the production and use of biotechnology. Data consists of official national and institutional policy documents, as well as interviews conducted with nine former students, along with their school notebooks and tests. The theoretical and methodological framework draws on the work of Michel Foucault. It is argued that neoliberal market values are embedded in the mathematics education, through the articulation of abstract and formal reasoning with techno-scientific knowledge, for the purpose of competitive production. The learning by research principle shapes students’ subjectivities to desire becoming techno-scientificized individuals. The ethical question of the subordination of the value of mathematics education to a neoliberal, predominantly marketized logic is raised as a challenge to the role of mathematics in contemporary cultures. 相似文献
The expansion of access to devices, as well as the production and publication options in social networks requires a broader definition of the traditional notion of personal digital storytelling. To get a deeper understanding of these practices in the group of adolescents, the objective of this article is to analyze what are the reasons that direct the publications of personal stories and what kind of filters, agents and consequences are articulated in these stories. To do this, the most qualitative part of an investigation on teenagers’ internet publication guidelines is synthesized. Specifically, the results of a semi-structured interview with 12 adolescents between 12 and 20 years are shown. The answers show that the interviewees’ perspective on what a digital story is goes beyond the format and varies depending on the network where it is published and the type of content. Thus, the emphasis and motivation of the publication has shifted from the digital - which has been incorporated with something normal and not differential - towards the personal, focusing the publications on the daily life of young people. An extension and refinement of the public-private dichotomy has been identified, maintaining general privacy guidelines above the dissemination of publications. As for filters, publications are preceded by the widespread use of image modification tools. Finally, the answers show the influence of personal agents, mostly friends and brothers, and technology agents, which determine the relationship between the type of story and the network where it is published.
Temperamental negative affect and insufficient sleep have been independently associated with behavior problems during early childhood. However, it is unknown whether these factors interact to contribute to behavioral difficulties in young children. The current study examined the interactions between temperamental negative affect and both sleep onset time and sleep midpoint, assessed by actigraphy, in predicting externalizing and internalizing behaviors in a sample of 117 children (34–69 months of age). Children with high temperamental negative affect and either later sleep onset time or later sleep midpoint were more likely to exhibit externalizing and internalizing behaviors. These results emphasize the association between temperamental negative affect and behavioral difficulties, particularly for children with insufficient sleep. 相似文献
Clinical skills and medical knowledge enable physicians to overcome the uncertainty of emergent and rare clinical scenarios. Recently, a growing emphasis on evidence-based medicine (EBM) has flooded medical curricula of universities across the globe with guideline-based material, and while it has given teachers and students new tools to improve medical education, clinical reasoning must be reaffirmed in its capacity to provide physicians with the ability to solve unexpected clinical scenarios. Anatomical education in medical school should have two main objectives: to acquire anatomical knowledge and to develop the skill of applying that knowledge in clinical scenarios. The authors present a clinical scenario in which an unexpected and rare complication occurred during a routine elective hip replacement surgery. The general surgeon presiding over the case, also an anatomy professor, solved the problem using clinical reasoning and anatomical knowledge. It was a clear example of how clinical reasoning is key in approaching unprecedented, rare, or unknown complications. The intention of this scenario is to remind colleagues and medical schools that, although EBM is the standard, educators must uphold sound clinical reasoning to best prepare health care providers for their careers. 相似文献
When studying verbal materials, both adults and children are often poor at accurately monitoring their level of learning and regulating their subsequent restudy of materials, which leads to suboptimal test performance. The present experiment investigated how monitoring accuracy and regulation of study could be improved when learning idiomatic phrases. Elementary school children (fourth and sixth-graders) were instructed to predict their test performance by providing judgments of learning (JOLs). They provided JOLs immediately after studying each idiom, after studying all idioms, or after studying all idioms followed by generating sentences in which the idioms were used. Correlations between JOLs and test performance showed that delayed-JOLs and delayed-JOLs with sentence generation were more accurate than immediate JOLs. JOLs after sentence generation also improved regulation of study compared to delayed-JOLs only. Analyses of JOL reaction times suggest that delayed-JOLs led children to retrieve the literal meaning of the idiom, whereas JOLs after sentence generation led children to focus on connections between studied information, contextual information, and prior knowledge. Sentence generation presents a promising method to improve regulation of study, and thus idiom learning. 相似文献

Interventions to increase the endorsement of the growth mindset (the belief that intelligence can be improved with effort) have been successfully implemented in schools. However, they rarely target children and young people with special educational needs and/or disabilities (SEND), a group who are more likely to endorse a fixed mindset, experience lower academic self‐concept and academic resilience, and be at risk of negative stereotyped attitudes. This quasi‐experimental study implemented a 10‐week PSHE programme as well as dedicated lessons with adapted classroom practices, for example, task framing and feedback, to promote the growth mindset message to young people with SEND (N = 18). Analyses of pre‐ to post‐intervention measures demonstrated moderate evidence for the intervention having increased students’ endorsement of the growth mindset, as well as anecdotal evidence for increased academic self‐concept, academic resilience and positive attitudes to disability. However, these effects were not sustained in follow‐up measures conducted 7 weeks post‐intervention. The intervention did not improve students’ academic performance. Although preliminary, findings demonstrate the viability of growth mindset interventions for children and young people with SEND, but suggest that interventions should be maintained for longer‐lasting effects. 相似文献
Research, aimed at constructing an instrument for measuring instructional climate, was conducted in 121 Dutch schools for senior general secondary education. The instrument comprised scales for students, teachers, heads of department and principals. All scales proved to be sufficiently reliable and valid. The results show that the following variables are significantly related to students' results in mathematics: students' enjoyment of mathematics; students' attitude towards high grades; students' enjoyment of learning; appreciation of how teachers prepare students for tests; students' appreciation of the teacher as a person; students' appreciation of teaching abilities; an orderly instructional climate in the classroom; frequent monitoring of student results; emphasizing achievement by teachers; and the principals' emphasis on a task oriented climate. 相似文献
