INTRODUCTION Recently, the application of the information technology into manufacturing fields gets more and more importance on the whole manufacturing shop floors. Currently, many researches reflect the effec- tiveness of knowledge-based production system re- lated to the exchange and management of various manufacturing information using information tech- nology via the Internet in order to increase the com- petitive power of industries. This research suggests a Web-based machining proce… 相似文献

Effect of encoding instructions on children's spatial and color memory: is there evidence for automaticity? 总被引:2,自引:0,他引:2
This experiment is concerned with assessing whether there is evidence for the automatic processing of spatial and color information by children and with the development of control of encoding operations. First, third, and fifth graders viewed pictures of simple objects that varied in color (red or green) and spatial location (left or right). Subjects were instructed to encode (a) only the item, (b) the item and its color, (c) the item and its position, (d) the item, its color, and its position. The data yielded evidence for nonchance incidental memory of spatial, but not color, information. The data also suggested that children at all age levels were able to control their encoding operations similarly, as there was no evidence for an interaction of development with encoding instructions. These findings are discussed with respect to a model for automatic encoding processes and work on memory for central and incidental information. 相似文献

The purpose of this study is to review the main perspectives or issues dealt with in the research on considered to be key
competences, in order to develop a fuller understanding of how human competence functions. As a result of this review, two
themes considered as having important implications for the actual practices can be identified: that there exists an holistic
nature with different aspects of a given competence and that influences of a contextual and cultural nature are factors which
affect the operation of human competence. By incorporating four characteristics and three domains of competence with the review
conducted in this study, we began to appreciate what the research on human characteristics related to key competences has
achieved and what is needed for future research. 相似文献

INTRODUCTION Video streaming service nowadays enjoys ex- plosive adoptions over all kinds of underlying net- works. To enjoy the freedom of tether-less connection over the wireless local area network (WLAN), we need to overcome many challenges of unstable wire- less channel due to fading, interference and so on. The scarce and fluctuating available bandwidth (together with time-varying delays and random/burst losses) can cause the video quality at the streaming client to be seriously deg… 相似文献

This study investigated the nature of interaction among teachers that occurred around the National Board certification (NBC) process and how that collegial interaction influenced teachers’ professional development. Qualitative interviews were conducted with 14 teachers who were either considering NBC, in the process, or had been awarded NBC. Interview data were analyzed using the constant comparative method. Results indicated that teacher interactions triggered by NBC helped one another's professional development in several ways: (a) enhancing reflection on teaching practice, (b) establishing a professional discourse community, (c) raising the standards for teaching performances, and (d) facilitating collaboration. Implications for teacher professional development were discussed. 相似文献

The recent next generation science standards in the United States have emphasized learning about complex systems as a core feature of science learning. Over the past 15 years, a number of educational tools and theories have been investigated to help students learn about complex systems; but surprisingly, little research has been devoted to identifying the supports that teachers need to teach about complex systems in the classroom. In this paper, we aim to address this gap in the literature. We describe a 2-year professional development study in which we gathered data on teachers’ abilities and perceptions regarding the delivery of computer-supported complex systems curricula. We present results across the 2 years of the project and demonstrate the need for particular instructional supports to improve implementation efforts, including providing differentiated opportunities to build expertise and addressing teacher beliefs about whether computational-model construction belongs in the science classroom. Results from students’ classroom experiences and learning over the 2 years are offered to further illustrate the impact of these instructional supports. 相似文献

It is often assumed that graduate students will develop as teacher educators simply by participating in a doctoral program. However, research has shown that doctoral students find the shift from teaching K-12 to preparing teachers to be a difficult transition. Within the context of a doctoral program community of practice established specifically for the purpose of examining this transition through self-study research, we sought to understand the shift in identity of a novice teacher educator working as an early field experience instructor with elementary science and mathematics preservice teachers. Our findings indicate that the process of self-study research, when supported within a community of practice, offered Jared the opportunity to recognize different aspects of his shifting professional identity, the dominance of particular aspects of his identity in certain situations, and the impact this was having on his students’ development as teachers. Developing this awareness of his adapting professional teaching identity from a classroom teacher to a teacher educator should help as he continues to develop his knowledge and skills working with teachers in different contexts and at different grade levels. Implications for how teacher education programs could better support the professional identity development of novice teacher educators through the use of a self-study focused community of practice are discussed. 相似文献

Academic language, which is characterized by the words and structure of the language of schooling, is an important teachable component of academic achievement. When compared to other strong predictors of academic achievement (e.g., decoding, fluency, vocabulary, comprehension), academic language is not as well understood or explicitly taught in schools. The purpose of this literature synthesis is to identify the instructional practices that currently have the best evidence to improve academic language and broader academic achievement outcomes. The most prolific study of academic language instruction occurs with English learner samples. In the current study, we sought high-quality empirical intervention studies conducted with English learners. We describe the components of instruction that explicitly address academic language skills, and we describe the impact on outcomes for English learner students as well as their English-only peers. 相似文献
