儿童学视角下教师教育课程的创新     

安桂清  方明生 《教育发展研究》2015,(2):19-25

儿童学课程的设置是当前国际教师教育课程的重要走向。由于能够体现教师作为儿童研究者的存在本质、拓展教师教育课程的知识基础和增强教师教育课程对社会的适应性,儿童学课程的嵌入对教师教育课程质量的提升将起到重要的作用。从我国的教育现实出发,借鉴国际大学儿童学专业课程设置的经验,教师教育课程需要以涵育教师的儿童学素养为目标,在课程结构上做出积极的调整,同时以问题领域为核心组织课程模块,践履"情景化的实践探究"的实施策略。  相似文献   

Inclusion Practices in Elementary Physical Education: A Social-cognitive Perspective     

Jihoun An  Karen S. Meaney 《International Journal of Disability, Development & Education》2015,62(2):143-157

This study explored inclusion practices in general physical education (GPE) from the experiences and perspectives of elementary physical education teachers. The stories of four teachers (two females, two males) between 27 and 57 years of age were gathered using the phenomenological methods of semi-structured interviews, photographs, school documents, and field notes. Bandura’s social-cognitive theory provided a conceptual framework to interpret the findings of this inquiry. Three themes emerged from the thematic analysis: engaging in learning; adapting strategies to meet students’ needs; and moving beyond the educational goals. The findings suggest that inclusion practices (teacher’s behaviours) in GPE were constructed by the dynamic interactions between teachers’ knowledge of disability and motivation to learn about their students (personal factors) and children’s needs and learning goals (environment).  相似文献

Diatom-inspired multiscale mineralization of patterned protein–polysaccharide complex structures

Marine diatoms construct their hierarchically ordered, three-dimensional (3D) external structures called frustules through precise biomineralization processes. Recapitulating the remarkable architectures and functions of diatom frustules in artificial materials is a major challenge that has important technological implications for hierarchically ordered composites. Here, we report the construction of highly ordered, mineralized composites based on fabrication of complex self-supporting porous structures—made of genetically engineered amyloid fusion proteins and the natural polysaccharide chitin—and performing in situ multiscale protein-mediated mineralization with diverse inorganic materials, including SiO₂, TiO₂ and Ga₂O₃. Subsequently, using sugar cubes as templates, we demonstrate that 3D fabricated porous structures can become colonized by engineered bacteria and can be functionalized with highly photoreactive minerals, thereby enabling co-localization of the photocatalytic units with a bacteria-based hydrogenase reaction for a successful semi-solid artificial photosynthesis system for hydrogen evolution. Our study thus highlights the power of coupling genetically engineered proteins and polysaccharides with biofabrication techniques to generate hierarchically organized mineralized porous structures inspired by nature.  相似文献

数字鸿沟视角下社会图书馆系统用户感知差异性实证研究     

严安 《现代情报》2014,34(1):79-83

百度产品如百度知道、百度百科、百度文库等是基于Web2.0应用的知识共享平台,用户不仅可以搜寻知识,而且可以贡献知识,被认为是重要的社会图书馆系统。本文结合数字鸿沟,探讨用户对百度产品易用性（能力鸿沟）和有用性（产出鸿沟）的感知差异,旨在推动社会图书馆系统的健康发展。首先进行量表设计;然后基于量表搜集数据;再针对数据进行分析,包括测量模型有效性检验、易用性和有用性的频数统计及相关分析;结合数据分析,用图的方式展现了用户在感知差异性上的分布状态,发现能力鸿沟和产出鸿沟之间存在高度相关性。  相似文献   

Solution pH change in non-uniform alternating current electric fields at frequencies above the electrode charging frequency     

Ran An  Katherine Massa  David O. Wipf  Adrienne R. Minerick 《Biomicrofluidics》2014,8(6)

AC Faradaic reactions have been reported as a mechanism inducing non-ideal phenomena such as flow reversal and cell deformation in electrokinetic microfluidic systems. Prior published work described experiments in parallel electrode arrays below the electrode charging frequency (f_c), the frequency for electrical double layer charging at the electrode. However, 2D spatially non-uniform AC electric fields are required for applications such as in plane AC electroosmosis, AC electrothermal pumps, and dielectrophoresis. Many microscale experimental applications utilize AC frequencies around or above f_c. In this work, a pH sensitive fluorescein sodium salt dye was used to detect [H⁺] as an indicator of Faradaic reactions in aqueous solutions within non-uniform AC electric fields. Comparison experiments with (a) parallel (2D uniform fields) electrodes and (b) organic media were employed to deduce the electrode charging mechanism at 5 kHz (1.5f_c). Time dependency analysis illustrated that Faradaic reactions exist above the theoretically predicted electrode charging frequency. Spatial analysis showed [H⁺] varied spatially due to electric field non-uniformities and local pH changed at length scales greater than 50 μm away from the electrode surface. Thus, non-uniform AC fields yielded spatially varied pH gradients as a direct consequence of ion path length differences while uniform fields did not yield pH gradients; the latter is consistent with prior published data. Frequency dependence was examined from 5 kHz to 12 kHz at 5.5 V_pp potential, and voltage dependency was explored from 3.5 to 7.5 V_pp at 5 kHz. Results suggest that Faradaic reactions can still proceed within electrochemical systems in the absence of well-established electrical double layers. This work also illustrates that in microfluidic systems, spatial medium variations must be considered as a function of experiment time, initial medium conditions, electric signal potential, frequency, and spatial position.  相似文献

Time spent on the Internet by multicultural adolescents in Korea     

Yangmi Lim 《Asia Pacific Journal of Education》2017,37(1):55-68

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them.  相似文献
