The positive effects of collaborative learning in a face-to-face environment are well known. However, little empirical research
exists to determine if such effects transfer to a computer-mediated environment. The purpose of this study was to investigate
the effect of computer-mediated collaboration on solving ill-defined problems. Participants first worked through a Web-based
instructional program that taught them a four-step problem-solving process. Then they worked in computer-mediated dyads or
alone to apply the steps to solve a realistic problem scenario. Results indicated that participants who worked in computer-mediated
collaborative dyads performed significantly better than did participants who worked alone. The results also indicated that
dyads spent significantly more time than participants in the individual treatment. Both treatment groups had positive attitudes
toward working collaboratively, Internet-based instruction, and transfer of problem-solving skills. Implications for the implementation
of computer-mediated collaboration in distance learning are discussed.

Upgrading the technological capabilities of foreign transnational subsidiaries in developing countries: The case of electronics in Thailand 总被引:1,自引:0,他引:1
Although substantial research shows the importance of transnational corporations (TNCs) to export-led growth in some developing countries, it cannot be assumed that TNC subsidiaries will automatically upgrade their capabilities through time or in a uniform fashion. This paper explores the pattern and pace of a sample of exporting TNC subsidiaries operating in the electronics industry in Thailand, showing how the different architectures of global value chains (centralised versus decentralised) shaped the technological progress of subsidiaries in this country. The case evidence suggests a wide variety in upgrading through time, with some subsidiaries failing to develop capabilities and remaining as ‘assembly only’ plants. Other more dynamic plants developed process engineering and product design skills, investing heavily in capability building. One common determinant in capability building appears to be the overall technology strategy of the global value chain leader (or parent company). In those subsidiaries which did not upgrade beyond assembly, technology decisions and processes were tightly controlled within the parent headquarter locations in relatively centralised international value networks. By contrast, the more dynamic plants exercised more discretion over local capability building. The latter operated in relatively decentralised networks, more open to domestic policies to encourage upgrading. The study suggests that governments should tailor upgrading policies not only according to the approximate level of capabilities attained by local subsidiaries, but also according to how receptive subsidiaries are to upgrading, arguing that capability building and policy receptiveness go hand-in-hand. Other countries hoping to upgrade the quality of foreign direct investment might also wish to focus policies on the more technologically capable, ambitious and receptive categories of foreign subsidiary. 相似文献

The study investigated the effects of three types of evaluation on preservice teachers’ performance, knowledge and attitudes
related to writing lesson plans that incorporate technology. Subjects were randomly assigned to one of the three treatment
conditions: teacher-evaluation, self-evaluation or peer-evaluation. All groups completed three class periods of instruction
on writing lesson plans, then each subject submitted his/her draft lesson plan. The drafts were evaluated by assigned evaluators
(teacher, self or peer), who provided scores and written feedback on a 15-item rubric. Students then revised their lesson
plans into final form. All three treatment groups improved their lesson plans significantly from draft version to final version,
with the teacher-evaluation group showing significantly greater improvement and writing significantly better final lesson
plans than each of the other two groups. Teacher-evaluation and self-evaluation groups had significantly higher scores on
a knowledge-based posttest than the peer-evaluation group. Several suggestions are discussed for making further improvements
in the self-evaluation and peer-evaluation processes. 相似文献

This paper outlines the use of the Writing with Symbols 2000 software to facilitate emergent literacy development. The program’s use of pictures incorporated with text has great potential
to help young children with and without disabilities acquire fundamental literacy concepts about print, phonemic awareness,
alphabetic principle, vocabulary development, and comprehension. The flexibility and features of the software allow early
childhood professionals to create a variety of early literacy tools for the classroom, including worksheets, storybooks, and
interactive activities. 相似文献

Do prodigies have extraordinary innate talent or do they just start very early and get much practice? Why do relatively few become eminent as adults? Is it because early and later success often need somewhat different abilities and gatekeepers rule? International chess is a good test domain for both issues because it has objective longitudinal data, unvarying task requirements, and no glass ceiling. Eight prodigies were studied. Some did not start chess particularly young but quickly reached high performance levels. Five already are very eminent, one becoming the youngest‐ever world champion at age 18. Chess prodigies probably do have great natural talent. Prodigies in domains with certain characteristics may tend to become eminent if they persist. 相似文献

The implementation of clay modeling and rat dissection into the human anatomy and physiology curriculum of a large urban community college 下载免费PDF全文
After a considerable amount of research and experimentation, cat dissection was replaced with rat dissection and clay modeling in the human anatomy and physiology laboratory curricula at La Guardia Community College (LAGCC), a large urban community college of the City University of New York (CUNY). This article describes the challenges faculty overcame and the techniques used to solve them. Methods involved were: developing a laboratory manual in conjunction with the publisher, holding training sessions for faculty and staff, the development of instructional outlines for students and lesson plans for faculty, the installation of storage facilities to hold mannequins instead of cat specimens, and designing mannequin clean‐up techniques that could be used by more than one thousand students each semester. The effectiveness of these curricular changes was assessed by examining student muscle practical examination grades and the responses of faculty and students to questionnaires. The results demonstrated that the majority of faculty felt prepared to teach using clay modeling and believed the activity was effective in presenting lesson content. Students undertaking clay modeling had significantly higher muscle practical examination grades than students undertaking cat dissection, and the majority of students believed that clay modeling was an effective technique to learn human skeletal, respiratory, and cardiovascular anatomy, which included the names and locations of blood vessels. Furthermore, the majority of students felt that rat dissection helped them learn nervous, digestive, urinary, and reproductive system anatomy. Faculty experience at LAGCC may serve as a resource to other academic institutions developing new curricula for large, on‐going courses.

This article provides a case study of union change in an environment in which radical school restructuring is taking place, and active strategies to weaken and marginalize organized teachers are being pursued by the state. The case study union is the National Union of Teachers in England. The article explores a number of different strategies open to teacher unions, utilizing a framework provided by Turner (2004). Drawing on data collected at a national level, and in three local authority areas, I argue that the National Union of Teachers’ response to the erosion of collective bargaining is best presented as an amalgam of strategies focused on workplace organizing, political campaigning, and coalition building. The data demonstrate considerable congruence between national and local strategies, although local data reveal considerable challenges in implementation and consequently considerable unevenness in local experiences. 相似文献

Although Adverse Childhood Experiences (ACEs) are linked to increased health problems and risk behaviors in adulthood, there are no studies on the association between ACEs and adults’ states of mind regarding their early childhood attachments, loss, and trauma experiences. To validate the ACEs questions, we analyzed the association between ACEs and emotional support indicators and Adult Attachment Interview (AAI) classifications in terms of unresolved mourning regarding past loss or trauma and discordant states of mind in cannot classify (U/CC) interviews. Seventy-five urban women (41 clinical and 34 community) completed a questionnaire on ACEs, which included 10 categories of abuse, neglect, and household dysfunction, in addition to emotional support. Internal psychological processes or states of mind concerning attachment were assessed using the AAI. ACE responses were internally consistent (Cronbach's α = .88). In the clinical sample, 84% reported ≥ 4 ACEs compared to 27% among the community sample. AAIs judged U/CC occurred in 76% of the clinical sample compared to 9% in the community sample. When ACEs were ≥ 4, 65% of AAIs were classified U/CC. Absence of emotional support in the ACEs questionnaire was associated with 72% of AAIs being classified U/CC. As the number of ACEs and the lack of emotional support increases so too does the probability of AAIs being classified as U/CC. Findings provide rationale for including ACEs questions in pediatric screening protocols to identify and offer treatment reducing the intergenerational transmission of risk associated with problematic parenting. 相似文献
