This study explored the concurrent and longitudinal relationships between reading and writing in young Chinese-as-a-second-language (CSL) learners’ sentence writing, using structural equation modeling. The participants comprised 126 Hong Kong senior primary ethnic minority students, whose literacy skills were assessed at two time points over the course of a year. In grade 5 (Time-1), they were assessed with Chinese character reading and reading comprehension measures to evaluate their reading ability. In grade 6 (Time-2), their sentence reading, sentence writing, and literacy component skills of Chinese character writing fluency and written syntactic skills were assessed. The results demonstrated that students’ reading and writing performances were substantially related both concurrently and longitudinally. Furthermore, (1) at Time-2, the component skills accounted for substantial portions of variance in sentence reading and writing skills, along with the relationship between them, while (2) Time-1 reading ability predicted Time-2 component skills and, through the mediation thereof, indirectly predicted sentence writing. Thus, in light of the linguistic characteristics of the Chinese language, literacy component skills are crucial component processes that connect reading and writing in CSL learners’ sentence writing. 相似文献

We report a facile and robust microfluidic method to fabricate polymeric core-shell microspheres as delivery vehicles for biomedical applications. The characteristics of core-shell microspheres can be precisely and easily tuned by manipulating the microfluidic double emulsion templates. The addition of a shell can significantly improve the versatility as well as functionality of these microspheres as delivery vehicles. We demonstrate that the nature of the shell material plays an important role in the properties of the core-shell delivery vehicles. The release kinetics is significantly influenced by the material of the shell and other characteristics such as the thickness. For example, by adding a poly(lactic-co-glycolic acid) (PLGA) shell to an alginate core, the encapsulation efficiency is enhanced and undesired leakage of hydrophilic actives is prevented. By contrast, adding an alginate shell to PLGA core can lead to a reduction of the initial release rate, thus extending the release period of hydrophobic actives. Microfluidic fabrication enables the generation of precisely controlled core-shell microspheres with a narrow size distribution, which enables the investigation of the relationship between the release kinetics of these microspheres and their characteristics. The approach of using core-shell particles as delivery vehicles creates new opportunities to customize the release kinetics of active ingredients. 相似文献

Abstract The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of “hard” Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field. 相似文献

Abstract The purpose of this study was to initiate systematic research on dance as a creative and expressive art form. Although the process of expression through movement has concerned dancers and dance teachers for some time, there have been few attempts at a systematic analysis of either the process or the product of dance expression. Dance has generally been considered immeasurable because of its peculiarities as an art form. While there is little apparent value in quantitative measurement of dance, qualitative measurement appears to have considerable value. It can sharpen the focus on principles of dance composition, contribute toward increased teaching effectiveness, enlarge dance's expressive range, and increase its ability to communicate. Specifically, this study attempted to determine how effectively modern dance communicates by using a systematic analysis of individual dance compositions. Samples of dance studies with specific intentions were choreographed and filmed. The dances were then viewed and evaluated by a selected and trained jury on (a) their ability to communicate emotional and physical qualities, (b) the type and structure of their composition, and (c) their choreographic and artistic effectiveness. Results of this study showed that least agreement was reached by the jurors in rating the dances according to structural strength and in identifying their composition type. Realistic vehicles of expression were more easily recognized than were abstract ones. There was substantial agreement on the emotion communicated by each composition. Presence of all the traditional dance elements appears unnecessary for effective communication. 相似文献

Personal and social education has become an important area of development in education in Hong Kong. Given that much of the literature on personal and social education is Anglo-American or European, what is the influence on the largely Chinese settings in Hong Kong? This paper will examine some of the debates of what constitutes personal and social education. The significance of competing contexts in the development of personal and social education will be analysed in detail. Comparisons will be made between Western and Chinese (especially Confucian) views on personal and social education. Attempts will be made to come up with a notion of personal and social education which is suitable for the Hong Kong context. 相似文献

SYNOPSISHigh-quality parental caregiving promotes children’s development from their day of birth or even earlier. Whether there are ways to predict, and ultimately enhance, parental caregiving quality during the prenatal stages of development has been less well understood. This circumstance is even truer when things do not go according “to plan.” In this commentary, we explore two possible scenarios, perhaps unexpected for expectant parents, that can affect children’s development: (1) postpartum parental displays of atypical behaviors and parental caregiving strategies (i.e., maternal/paternal depression) and (2) postpartum child displays of atypical behaviors (i.e., autism spectrum disorder). 相似文献

中小学几何教学之我见 总被引:1,自引:2,他引:1
中小学几何课程应当教些什么一直是个具有争议的课题.回顾欧氏几何的发展历史有助于我们对几何有更深入的理解.新加坡中小学几何课程受到“新数学”及“回归基础”等各种思潮的影响,新的数学大纲计划在2007年正式推出,在几何教学上也会有相应的变动.对于中小学几何课程应当教授哪些内容我们至今仍未能达成共识.事实上,几何本身是无所不在的.真正的关键之处并不在于教的内容,即教些什么,而在于教的方法,即如何施教.中小学的数学课应当采取代数与几何并重的方式进行教学. 相似文献

This paper reports a novel, mobile-assisted, game-based learning design for Chinese character learning. In playing the ‘Chinese-PP’ game in a 1:1 (one-device-per-student) setting, each of the 31 target students in Primary 3 (9 years old) is assigned a Chinese character component. A student may make use of his/her own and peers’ character components to form a legitimate Chinese character, and invite the peers with matching components to join his/her group. The intention is to assist the students in developing general orthographic awareness (understanding the structures of Chinese characters) through social negotiation. In this paper, the students’ collaborative learning processes in three game sessions were analysed. The relationships between students with varied learning styles and their game behaviours and learning gains were unveiled as a result. Through the Chinese-PP learning activities that stimulated active peer coaching and social learning, we found that all the target students became active learning participants and achieved high learning gains in the last game session. Recommendations for the future development of such a novel learning approach will also be given. 相似文献
