利用眼动分析技术,通过设置不同难度和分值的计算项目,探讨了在有时间压力下学习者的学习时间分配。结果发现:(1)在首次项目选择上,学习者优先选择学习率最高的项目;(2)在学习过程中,学习者的项目选择次序也是根据学习率由高到低。总之,在学习时间分配上,如果需要权衡难度与分值,学习者会考虑单位时间的获益,也就是以学习率为议程的主要依据。研究不仅利用眼动分析技术证实了基于议程的学习时间分配模型,而且进一步揭示了学习率是设置学习时间分配议程的重要依据。  相似文献

According to legislation, take-overs initiated by the driver must always be possible during automated driving. For example, when drivers mistrust the automation to handle a critical and hazardous lane change, they might intervene and take over control while the automation is performing the maneuver. In these situations, drivers may have little time to avoid an accident and can be exposed to high lateral forces. Due to lacking research, it is yet unknown if they recognize the criticality of the situation and how they behave and perform to manage it. In a driving simulator study, participants (N = 60) accomplished eight double lane changes to evade obstacles in their lane. Time-to-collision and traction usage were varied to establish different degrees of objective criticality. To manipulate these parameters as required, participants were triggered to take over control by an acoustic cue. This setting shows what might happen if drivers disable the automation and complete the maneuver themselves. The results of the experiment demonstrate that drivers rated objectively more critical driving situations as more critical and responded to the hazard very fast over all experimental conditions. However, their behavior was more extreme with respect to decelerating and steering than necessary. This impaired driving performance and increased the risk of lane departures and collisions. The results of the experiment can be used to develop an assistance system that supports driver-initiated take-overs.  相似文献

Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face‐to‐face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family‐centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities.  相似文献

In spite of its different cantonal jurisdictions and traditions, the development of religious education in Switzerland over the past decade has taken a common direction: the state has assumed a more active role in the field of religious education in public (state‐run) schools. In this article, we ask the question: How do key social actors interpret these reforms and how do these interpretations relate to the social structure of religion in Switzerland, in particular with respect to the majority category of the so‐called distanced Christians? Drawing on qualitative interviews with members of the schools’ teaching staff, school administrators, and church representatives, the article highlights a dominant interpretative pattern that frames the socially accepted representation of religion in public schools. Thus, rather than addressing the pedagogical dimension of religious education, we discuss the significance of this pattern for the debate on the public presence of religion in Switzerland and Europe.  相似文献

A 2‐year longitudinal study of 33 children aged 4–6 years was conducted to clarify the developmental relationship between calculation skill and finger dexterity, as well as the selectivity of the predictive power of finger dexterity on later calculation skill. We examined individual developmental change in the relationship between addition performance and finger dexterity and observed whether children fit a linear developmental pattern. Multiple regression analysis showed that participants' performance on addition tests was strongly predicted by their finger dexterity. However, their performance on vocabulary tests was not strongly influenced by finger dexterity. These findings suggest that calculation skill in children aged 4–6 years is strongly related to finger dexterity.  相似文献

Individual health counseling is a form of intervention designed to minimize the effects of chronic health disease and to offer a path towards good health practices. The aim of the present study was to explore the experiences of those persons who participated in health counseling in order to assess the psychosocial significance of the counseling upon their health behavior. In addition the study was concerned with the factors which underlay peoples' decision to sign up for health counseling. The research involved 11 semi‐structured interviews with individuals who had participated in a municipality based health counseling program. Data was analyzed using Malterud's systemic text condensation and a theoretical framework around Bandura's social cognitive theory. Analysis revealed that an approach tailored to each individual with minor short‐term goals accompanied by feeling supported by the counselor produced the greatest impact on behavior. Receiving feedback from the counselor and feeling positive about the relationship were seen as essential. These aspects were also crucial in the decision to undertake health counseling. The study indicates that whether individual's sign up on their own initiative or conversely are invited to join the program has no influence upon their motivation to change their behavior. Overall the respondents demonstrated improvement in their behavior and attitudes towards their health. However, the study also indicates that this form of intervention is less or even ineffective without the support of the individual's immediate family.  相似文献

Experiential learning opportunities are powerful in shaping positive supervisor behaviours. We were interested in examining the positive experiences of supervisors-in-training during their first practice experience as supervisors. Our study was guided by two research questions: (a) what are the experiences that supervisors-in-training viewed as positive during the course of providing clinical supervision to master's-level counselling trainees? and (b) how did these positive experiences contribute to their professional development? We employed a variation of the consensual qualitative research method developed by Hill, Thompson, and Nutt-Williams (1997) and interviewed 10 supervisors-in-training regarding their positive experiences in supervising master's-level counselling trainees. The results included five major categories of positive experiences: (a) the positive value of feedback; (b) enhanced confidence in using a wider variety of supervision tasks and procedures; (c) the impact of the experience on other aspects of professional practice; (d) increased familiarity with the multiple roles of the supervisor; and (e) for some, increased comfort navigating co-supervision dynamics. Each of these categories included subcategories. We discuss our findings within the context of supervision training in graduate education.  相似文献

Careers advisers in the UK have experienced significant change and upheaval within their professional practice. This research explores the role of postgraduate-level professional development in contributing to professional identity. The research utilises a case study approach and adopts multiple tools to provide an in-depth examination of practitioners' perceptions of themselves as professionals within their lived world experience. It presents a group of practitioners struggling to define themselves as professionals due to changing occupational nomenclature resulting from shifting government policy. Postgraduate professional development generated a perceived enhancement in professional identity through exposure to theory, policy and opportunities for reflection, thus contributing to more confident and empowered practitioners. Engagement with study facilitated development of confident, empowered practitioners with a strengthened sense of professional self.  相似文献
