This paper reports the development of a scheme of characterising pedagogical practices in initial teacher education classes. The scheme is intended to provide baseline data on classroom pedagogical practices in Singapore’s sole provider of initial teacher education (ITE). This study is original in that the research team has found no reports of independent research to characterise, through video analysis of classroom practices, the pedagogical practices experienced during ITE. By characterising the pedagogical practices of a purposive sample of ITE lessons run at the National Institute of Education Singapore, this study contributes an initial scheme to produce detailed and layered representations of pedagogical practices through video recordings, which opens a new approach to research on teacher education. The implications with regard to teacher education policy and practice will be discussed. 相似文献

In this paper, a control scheme is proposed for a group of elliptical agents to achieve a predefined formation. The agents are assumed to have the same dynamics, and communication among the agents are limited. The desired formation is realized based on the reference formation and the mapping decision. In the control design, searching algorithms for both cases of minimum distance and tangents are established for each agent and its neighbors. In order to avoid collision, an optimal path planning algorithm based on collision angles, and a self-center-based rotation algorithm are also proposed. Moreover, randomized method is used to provide the optimal mapping decision for the underlying system. Two examples and analyses are presented to demonstrate the effectiveness and potential of the new control scheme. 相似文献

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument. 相似文献

The perspective of six Malaysian students on playing video games: Beneficial or detrimental? 总被引:1,自引:0,他引:1

This study provides a glimpse into understanding the potential benefits as well as harm of playing video games from the perspective of six Malaysian secondary school students, aged 16-17 years old. The rationale of the study is to enable parents, educators, administrators and policy makers to develop a sound understanding on the impact of playing video games before making any judgment on the contemporary youth culture. Thus, further decision on the acceptance of video games as a new innovation in school or at home could be considered. Although this study is not very extensive, the findings suggest that playing video games contributes to cognitive, social, motivational and emotional development. However, potential harms do exist. Parents play an important role in guiding their children either directly or indirectly, as indicated by the respective students. Caution is advised in the interpretation of the study's findings as it is solely based on the perspectives of the students, as the first person's views. Nevertheless, each student has their very own perspective on the impact of video games on them. 相似文献

孟子与荀子的政治观从表面上看大多是对立的,但在实际上并不矛盾,他们往往说的不是一个层面上的问题。就其政治大思路而言,二者是一致的,都倡导人治,都是道德主义的,有其“同归而殊途”的内在逻辑。 相似文献

While there is evidence of the growing popularity of iPads and other tablets in K–12 education, little is understood about how teachers use these devices in their instruction. This study examines 342 teachers' comfort level with and perception toward iPad use and any changes that occurred over the implementation year. Using a mixed-methods design, this study found significant differences in comfort level by years of teaching and school levels. Female teachers, teachers with 20 years or less of teaching experience, and elementary school teachers were more positive about their perception toward iPad use than the other groups. High school teachers' perception was the lowest overall. Analyses of teacher interviews revealed affordances, challenges, and diverse ways of how teachers used iPads in their instruction. Implications for practice and research are discussed. 相似文献
