Two language acquisition processes (comprehension preceding production of word order, the noun bias) were examined in 2- and 3-year-old children (n=10) with autistic spectrum disorder and in typically developing 21-month-olds (n=13). Intermodal preferential looking was used to assess comprehension of subject-verb-object word order and the tendency to map novel words onto objects rather than actions. Spontaneous speech samples were also collected. Results demonstrated significant comprehension of word order in both groups well before production. Moreover, children in both groups consistently showed the noun bias. Comprehension preceding production and the noun bias appear to be robust processes of language acquisition, observable in both typical and language-impaired populations. 相似文献

Understanding and describing mathematical knowledge for teaching: knowledge about proof for engaging students in the activity of proving 总被引:1,自引:0,他引:1
This article is situated in the research domain that investigates what mathematical knowledge is useful for, and usable in,
mathematics teaching. Specifically, the article contributes to the issue of understanding and describing what knowledge about
proof is likely to be important for teachers to have as they engage students in the activity of proving. We explain that existing
research informs the knowledge about the logico-linguistic aspects of proof that teachers might need, and we argue that this knowledge should be complemented by what we call knowledge of situations for proving. This form of knowledge is essential as teachers mobilize proving opportunities for their students in mathematics classrooms.
We identify two sub-components of the knowledge of situations for proving: knowledge of different kinds of proving tasks and knowledge of the relationship between proving tasks and proving activity. In order to promote understanding of the former type of knowledge, we develop and illustrate a classification of proving
tasks based on two mathematical criteria: (1) the number of cases involved in a task (a single case, multiple but finitely
many cases, or infinitely many cases), and (2) the purpose of the task (to verify or to refute statements). In order to promote
understanding of the latter type of knowledge, we develop a framework for the relationship between different proving tasks
and anticipated proving activity when these tasks are implemented in classrooms, and we exemplify the components of the framework
using data from third grade. We also discuss possible directions for future research into teachers’ knowledge about proof.

In this essay, Deborah Bird Rose takes up Val Plumwood's challenge that Western thought needs radical revitalization by pursuing the liveliness of the biosphere and human ontologies of connectivity. The first part looks at obstacles to the West's understanding of Earth as a place of lively, interactive connectivities that promote diversity, complexity, and relationality. In this context Rose offers a brief overview of Indigenous animisms. The second part explores the question of liveliness. It is taken as given that the West now seeks ontological legitimacy in science, and so this discussion focuses on what biological scientists have contributed to contemporary ontology wars. The third part examines trauma in the Garden of Eden narrative, highlighting both the disaster of the story and its continuing relevance. Drawing on the work of theologians, in particular, Rose seeks in this section to recuperate a mythic foundation for a Western animism from within that great site of loss. 相似文献

‘Motivation’ is a significant concept for teachers and students during programmes of learning which lead explicitly to high stakes assessments and examinations. This systematic literature review surveys current research evidence to find out how secondary school teachers use motivational strategies specifically in respect of student academic assessment and performance. Six research studies were identified describing the behaviours secondary school teachers engaged in to improve student performance in assessment. Taken together, the studies presented show the importance of teacher behaviours to students’ academic performance, with both positive and negative impacts. The review highlights a need for further research on teacher knowledge of the effects of teacher behaviour upon the motivation of students. The review recommends collaboration between teachers and students specific to the context of learning programmes that lead to high-stakes assessments, in order to provide a locally sensitive knowledge base for teachers’ practice. 相似文献

Adopting a longitudinal approach, this article examines downward occupational mobility (DOM) later in working life and its effects on job satisfaction and perceptions of working conditions of older workers in Europe. The main aim was to test whether the risk that workers will be negatively impacted and marginalized in the labor market due to demotion into lower quality jobs is offset by benefits. Based on an ordinal logistic regression of merged Survey of Health, Ageing and Retirement in Europe and English Longitudinal Study of Ageing datasets, the study found a positive significant impact of DOM on overall job satisfaction. Moreover, DOM was associated with a statistically significant reduction in workload pressure, although it did increase physical work demand. This article adds to the literature on marginalization of workers with indications that the lower income and status associated with DOM at older ages may have offsetting benefits. 相似文献

This case examines how functionalist approaches manifest culturally based on users’ contexts. The authors conduct a critical visual semiotic analysis of the race and Hispanic origin questions on the 2010 U.S. Census form, demonstrating how incongruities in design potentially harm people. This demonstrates a need for adding critical analyses to design and research and it refocuses the Society for Technical Communication’s value of promoting the public good on to design and documentation in order to fight injustice. 相似文献

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families. 相似文献

ABSTRACTFew autism programmes address the needs of adolescents and young adults, and those that do are unlikely to include individuals with autism in the design and evaluation of the programme. This study involved nine youth with autism (ages 16–25) in the development and evaluation of a peer teaching programme where they taught three-dimensional modelling to other students with autism spectrum disorder. The methodology was participant-oriented research where the students with autism were co-designers and programme evaluators in the research. This approach highlighted their unique strengths and abilities and shifted the power such that they were leaders and not simply the recipients of knowledge from instructors. Four themes emerged through the qualitative analysis of the students’ perceptions of the peer teaching programme: 1) the meaning of peer teaching, 2) motivations for peer teaching, 3) challenges and 4) coping with the challenges of the role. 相似文献

One hundred eighty-one experienced teachers (elementary and junior high), and 189 preservice teachers were surveyed regarding their perceptions of school psychologists. The survey instrument used essentially the same categories as Styles in 1965, including: (a) level of training, (b) effectiveness, (c) qualifications for tasks, and (d) usefulness in specific duties. Analysis of the survey data showed there were significant differences between preservice and experienced teachers' effectiveness ratings of school psychologists on eight tasks typically performed by school psychologists. Significant differences also were found between preservice and experienced teachers on their ratings of school psychologists' qualifications to undertake specific tasks, although almost half of the experienced teachers were unable to rate the effectiveness of school psychologists. There was a small, but significant, negative relationship between the amount of contact with the school psychologist and the perceived effectiveness. Limitations inherent in survey methodology and the need to foster greater teacher awareness of the school psychologist's role are discussed. 相似文献

The premise that underlies the preservice‐teacher‐education programme at Monash University is the need to focus on the nature of learning (for example, Gunstone et al., 1993). One approach currently being used to enhance this process is the use of portfolios. The portfolio is an open‐ended task designed to explore teaching from many different vantage points. It is organised as a dynamic assessment task through which the student teachers work on developing their understanding of what it means to be a science teacher, and the teaching portfolio itself is a mixture of artefacts designed to help student teachers demonstrate this to others. This paper reports on the effectiveness and value of portfolios in helping preservice teachers learn about learning and teaching. 相似文献
