Hearing loss during the critical period for language acquisition restricts spoken language input. This input limitation, in turn, may hamper syntactic development. This study examined the comprehension, production, and repetition of Wh-questions in deaf or hard-of-hearing (DHH) children. The participants were 11 orally trained Hebrew-speaking children aged 9.1-12.4 with moderate-to-profound hearing loss from birth, who consistently used hearing aids or cochlear implants and who had difficulties understanding relative clauses. Experiment 1 tested the comprehension of Wh-questions using a picture selection task, comparing subject with object questions and who- with which-questions; Experiment 2 tested the production of subject and object who-questions using an elicitation task; and Experiment 3 tested the repetition of Wh-questions and other structures derived by Wh-movement. All the DHH participants showed difficulty in the comprehension, production, and repetition of object questions, and their performance was significantly below that of hearing children. In contrast, they repeated embedded sentences without movement well, indicating that their deficit is in syntactic movement rather than embedding or the CP node in the syntactic tree. The results provide additional evidence that DHH children have difficulties with Wh-movement and emphasize that Wh-questions, which are crucial for communication, can be severely impaired in these children. 相似文献

Performance support systems are mechanisms enabling users) productivity while reducing training expenses as support is being delivered in real time, often eliminating the need for costly pre‐performance training. Mobile technologies have created new opportunities for improved performance support systems, especially for tasks performed outside the offi ce. This article describes the fi rst mobile learning and performance support initiative taken by the Israeli Air Force. The project included the development and eff ectiveness pilot study of a learning and performance support application delivered via tablet to helicopter engine technicians. The application provided support videos and illustrations of maintenance routines, thereby enabling learning and practicing at the same time. Pilot study results show high performance levels of application users compared to those applying traditional methods. Results also show that self‐effi cacy levels were not aff ected by the successful performance achieved when using the mobile performance support application. Plans to expand mobile support use are also described. 相似文献

Literature has shown that on-the-job professional development programs are most beneficial when they are long-term, focused on students’ learning, and linked to the curricula. We hypothesized that the higher the control teachers have over job professional development processes, and the greater the resemblance of these processes to the typical teaching culture in classrooms, the greater the teachers’ satisfaction with job professional development processes. The findings of this study demonstrate that the main factors affecting teachers’ satisfaction with the instructional programs are related to their desire to maintain instructional processes “close to home”, and to shape these processes in accordance with their needs and expectations. The implications of the study are discussed with relation to decision-makers in the school setting and at the local authorities’ level. 相似文献

This study probes teachers' attitudes toward parental involvement in schools as a function of four types of school governance as suggested by Bauch and Goldring. Participants of the study included headteachers, chairpersons of parents' committees, and teachers of 11 primary schools in a medium-sized town in Israel. A discriminant analysis found different profiles of teachers' attitudes toward parental involvement: resistant and negative attitudes characterized schools where parents were empowered. Ambivalent attitudes characterized schools with professional and bureaucratic modes of governance, and positive attitudes were found in schools with partnership governance. This implies that the latter mode of governance is a promising step toward a community-oriented approach. 相似文献

How much does a successful collaboration between a university researcher and a funding source affect the researcher's future preference of that source? To examine this relationship, another crucial variable is added, namely, the individual's level of dependency on funding sources. It is hypothesized that given a low level of dependency, if researchers have had a satisfactory experience with a funding source, they will be more likely to prefer collaboration with that source than if they did not have a satisfactory relationship. Given a high level of dependency, past experience will not make a difference on preference. The effects of past experience on people's preferences are examined based on a survey of American university researchers. The data show that past experience has a strong impact on one's preference, but this effect is true for all researchers, regardless of their level of dependency on external support. Implications for funding sources, and social scientists using resource dependency as the theoretical framework are discussed. 相似文献

Experienced teachers possess a unique teaching knowledge comprised of an inter-related set of knowledge and beliefs that gives direction and justification to a teacher’s actions. This study examined the expansion of two components of pedagogical content knowledge (PCK) of three in-service teachers in the course of a professional development program aimed at designing new teaching and learning materials suggested by the teachers themselves. The research presents an enlargement of previous PCK representations by focusing on a detailed representation of two main PCK domains: teaching and learning, including ten PCK components that emerged in the course of data analysis. This representation enabled revealing the unique PCK held by each teacher and to characterize the expansion of the two components of the participating teachers’ PCK during the long-term professional development program. Retention of major parts of the expanded PCK a year after termination of the program implies that designing and implementing new teaching and learning materials based on the teachers’ experiences, needs, and knowledge in a workshop format accompanied by biology and science education courses might provide a powerful means for PCK expansion. We recommend that designers of professional development programs be aware of the unique PCK held by each teacher in order to promote meaningful professional development of each teacher. Moreover, the PCK representations that were identified in the course of this study enabled clarifying the “orientation toward teaching science” category of PCK which appears to be unclear in current literature. 相似文献

The present study investigates the performance of persons with reading disabilities (PRD) on a variety of sequential visual-comparison tasks that have different working-memory requirements. In addition, mediating relationships between the sequential comparison process and attention and memory skills were looked for. Our findings suggest that PRD perform worse than normally achieving readers (NAR) when the task requires more than a minimal amount of working memory, unrelated to presentation rate. We also demonstrate high correlations between performance on the task with the most working-memory demands and reading-related skills, suggesting that poor working-memory abilities may be one of the underlying mechanisms of dyslexia. The mediating model analysis indicates that order judgment tasks are mediating to verbal working memory, suggesting that visual sequence memory precedes auditory sequence memory. We further suggest that visual tasks involving sequential comparisons could probe for poor working memory in PRD. 相似文献

Kindergarteners treat certain social categories as natural kinds. This study addressed how children pick out social categories. Ninety‐one 19‐ and 26‐month‐olds were familiarized to exemplars of categories of people (e.g., Blacks–Whites, men–women) and animals (e.g., cows–horses). Participants then saw a picture matching the familiarization category and another that did not, and were asked to select which was like the familiarization pictures. For half of the participants, a label was attached to familiarization exemplars, while for the other half, no label was mentioned. The main finding was that for the younger toddlers, labels significantly improved recognition of the categories of people, but not of animals. These results are taken to support the notion that social categories are indeed culturally constructed. 相似文献

Framed as collective case studies, this study examined the perspectives that mentors, who are considered exemplary in the field, exhibit towards mentoring in different mentoring contexts in the Israeli school system from a variety of view points: The mentors themselves, their mentees, supervisors, school principals, and project leaders. Mentoring contexts are distinguished by their organisational, instructional and professional orientations towards teaching and mentoring. Perspectives towards mentoring are reflected in the language that the mentor uses in order to describe his/her work and the behavior that the mentor exhibits as it plays out in his/her actions. The findings of the study reveal that, despite the different contexts of practice, star mentors shared common perspectives towards mentoring in terms of educational ideologies and envisioned roles and practices, exhibited through the use of a similar professional language. We also learned that these attributed meanings were highly congruent with their mentees, principals, supervisors and colleagues' perceptions of the mentors' practice. The common emergent themes that surfaced in mentors and their respective participants' characterizations of their practice were: Organisational skills, interpersonal relationships, integration of theory and practice, knowledge and expertise, challenge, modelling and reflexivity. Mentors also acted upon some of these characterizations in unique, idiosyncratic ways, guided by the distinctiveness of their organisational and educational mentoring context. Thus, alongside similar ideologies and beliefs across contexts we also identified differences as to the emphasis that each mentor gave to a particular aspect of organisation, knowledge and relationships. 相似文献
