Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed. 相似文献

This article provides background on national movements toward expanded school mental health (ESMH) programs and school‐based health centers (SBHCs), and presents advantages and challenges of joining these two systems of child and adolescent health care. Delivering ESMH through SBHCs promotes an interdisciplinary approach, health–mental health care integration, and benefits including enhancing referral bases, improving screening of problems, and enhanced confidentiality and privacy. But this integrated approach also presents challenges including managing referrals and significant needs, handling crises, building a focus on prevention and mental health promotion, handling administrative demands, and coping with limited resources. These challenges, ideas for overcoming them, and future directions for this promising service delivery approach are discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 297–308, 2003. 相似文献

The design of motivational agents and avatars 总被引:1,自引:0,他引:1
Amy L. Baylor 《Educational technology research and development : ETR & D》2011,59(2):291-300
While the addition of an anthropomorphic interface agent to a learning system generally has little direct impact on learning,
it potentially has a huge impact on learner motivation. As such agents become increasingly ubiquitous on the Internet, in
virtual worlds, and as interfaces for learning and gaming systems, it is important to design them to optimally impact motivation.
The focus of this paper is on the design of agents and avatars (one’s self-representation as a visual agent) for enhancing
motivational and affective outcomes, such as improving self-efficacy, engagement and satisfaction, moderating frustration,
and/or improving stereotypes. Together with motivational messages and dialogue (which are not discussed here), the agent’s
appearance is the most important design feature as it dictates the learner’s perception of the agent as a virtual social model,
in the Bandurian sense. The message delivery, through a human-like voice with appropriate and relevant emotional expressions,
is also a key motivational design feature. More research is needed to determine the specifics with respect to the ideal agent
voice and the role of other nonverbal communication (e.g., deictic gestures) that may contribute to the agent’s role as an
embodied motivator, particularly in the long-term. 相似文献

The purpose of this study was to examine the extent to which three teachers’ professional experience and existing orientations
toward teaching and learning mathematics and science influenced their implementation of a project-based curriculum (i.e. project-based
learning (PBL)). Data sources included interviews, videotapes of classroom activity, and a teaching philosophy questionnaire.
Data analysis was conducted using an iterative coding technique. We found coherency between the teachers’ perceived orientations
and their emergent ideas about PBL, their sense of PBL as being compatible with their goals, and the specific challenges with
which they struggled. All the teachers wanted their students to be successful; however, different definitions of success led
to quite different approaches toward teaching, and for the most part, these differences appeared to have occurred because
of existing orientations the teachers held for teaching their discipline. Implications for professional development taking
into account teachers’ orientations and thus their professional experience are discussed, as well as disciplinary challenges
to using PBL. 相似文献

The authors evaluated an unfolding case‐based approach to a practicum in counseling course infusing crisis, trauma, and disaster preparation for changes in students’ crisis self‐efficacy across a semester. The course, informed by constructivist‐developmental pedagogy and centered on the unfolding case, resulted in significant increases in students’ crisis self‐efficacy. 相似文献

A comprehensive, quantitative evaluation of an educational intervention program designed to reduce the attrition of minorities from the biological sciences was undertaken to ascertain whether such efforts adequately address the problem. Program participants had greater odds of persisting in basic math and science courses, and of graduating in biology, than did a comparison group, controlling for demographics and academic preparation. Undergraduate research greatly increased the odds of positive graduation outcomes. Program participants were also more likely to pursue graduate study than were university graduates overall. This evaluation demonstrates the value of such programs in increasing the representation of minorities in science. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 861‐881, 2004. 相似文献

Pedagogical Agents as Learning Companions: The Role of Agent Competency and Type of Interaction 总被引:1,自引:0,他引:1
Yanghee Kim Amy L. Baylor 《Educational technology research and development : ETR & D》2006,54(3):223-243
This study was designed to examine the effects of the competency (low vs. high) and interaction type (proactive vs. responsive)
of pedagogical agents as learning companions (PALs) on learning, self-efficacy, and attitudes. Participants were 72 undergraduates
in an introductory computer-literacy course who were randomly assigned to one of four treatments: Low-Proactive, Low-Responsive,
High-Proactive, and High-Responsive. Results indicated a main effect for PAL competency. Students who worked with the high-competency
PAL in both proactive and responsive conditions achieved higher scores in applying what they had learned and showed more positive
attitudes toward the PAL. However, students who worked with the low-competency PAL reported significantly enhanced self-efficacy
beliefs in the learning tasks. Also, there was a main effect far PAL interaction type. A proactive PAL had a significantly
positive impact on recall. These different results on learning and motivational outcomes suggest that the competency and interaction
type of a PAL should be designed according to the desired learning and motivational goals. 相似文献

The Effect of Hearing Impairment on the Quality of Attachment and Mother-Toddler Interaction 总被引:1,自引:0,他引:1
In the present study, 41 hearing impaired and 41 hearing toddlers together with their hearing mothers were observed in Ainsworth's Strange Situation and during free play. Both security of attachment and ratings of maternal and toddler behavior during free play were remarkably similar for the hearing impaired and hearing dyads. In addition, security of attachment was related to the ratings of maternal and toddler behavior in a similar way for the hearing impaired and hearing toddlers. The results suggest that development of a secure attachment and maintaining a good mother-toddler relationship does not depend on normal language development during the toddler years. 相似文献
