Relooking Assessment: A Study on Assessing Developmental Learning Outcomes in Toddlers

In most countries the funding for early childhood education has increased and governments in some countries have taken serious steps to bring about positive change in the profession. However, the increase in funding by governments and other funding organisations around the world has, understandably, attracted increased accountability as these organisations need to know that their financial investments are achieving desired outcomes. To seek evidence that positive learning outcomes have indeed been achieved through these investments is a reasonable request, and there is a shared responsibility and accountability for professionals to provide appropriate evidence. The downside, however, can be the request for standardised test information, as if performance on such tests provides proof of all desired outcomes. More than ever before, it is important for early childhood educators to be able to provide accurate, objective information about children’s assessment in ways other than by standardised testing, which may not reflect the complex reality of children’s lives. This paper reports on a research study in Singapore that investigated curriculum effectiveness using developmental learning outcomes as a means of assessing children. The research was devised to examine if eight specified broad developmental learning outcomes could measure the effectiveness of the curriculum by assessing children’s learning as shown in qualitative data. Practical examples showed evidence of children’s learning and the role of the educator in facilitating and documenting developmental learning outcomes.     

Characteristics of the home context for the nurturing of gifted children in Saudi Arabia

This study investigates factors in the home environment and their influence on children’s analytical, creative, and practical skills. A sample of 294 gifted children (195 male) was recruited from grades 4–7 in Saudi Arabia, where the family context is highly influenced by the principles of Islam. Results did not confirm the effect of birth order, but showed that (1) mother’s education was an important factor for gifted children’s creativity; (2) the number of boys in the family was negatively associated with gifted boys’ creativity (r?=??.21); and (3) Quran-related learning experiences were positively related to gifted girls’ analytical (r?=?.46) and creative (r?=?.42) skills. Implications for understanding non-Western environments for gifted children are discussed.     

耶律楚材家族边塞与赠别思归作品分析

在丝绸之路上,有一定数量的契丹文化遗存.其中,耶律楚材祖孙三代在随蒙元大军西征东讨时,走过丝绸之路并创作了许多诗文.这些诗文大体可分为两类,一类为描写边塞战争之作,一类为赠别思归之作.其边塞战争作品包含四类内容,一是征战场景,二是止战优抚,三是劝谏开疆拓土,四是抒写征人思妇之情.其赠别思归作品一为赠别,一为思归,赠别作品主要包含四类,一是惜别伤怀,二是劝说留客,三是欣然相送或劝人建功立业,四是劝诫勉励侄孙后辈;思归作品主要包含两类,一是思亲,二是思乡.

Serrated lithium fluoride nanofibers-woven interlayer enables uniform lithium deposition for lithium-metal batteries

The uncontrollable formation of Li dendrites has become the biggest obstacle to the practical application of Li-metal anodes in high-energy rechargeable Li batteries. Herein, a unique LiF interlayer woven by millimeter-level, single-crystal and serrated LiF nanofibers (NFs) was designed to enable dendrite-free and highly efficient Li-metal deposition. This high-conductivity LiF interlayer can increase the Li⁺ transference number and induce the formation of ‘LiF–NFs-rich’ solid–electrolyte interface (SEI). In the ‘LiF–NFs-rich’ SEI, the ultra-long LiF nanofibers provide a continuously interfacial Li⁺ transport path. Moreover, the formed Li–LiF interface between Li-metal and SEI film renders low Li nucleation and high Li⁺ migration energy barriers, leading to uniform Li plating and stripping processes. As a result, steady charge–discharge in a Li//Li symmetrical cell for 1600 h under 4 mAh cm⁻² and 400 stable cycles under a high area capacity of 5.65 mAh cm⁻² in a high-loading Li//rGO–S cell at 17.9 mA cm⁻² could be achieved. The free-standing LiF–NFs interlayer exhibits superior advantages for commercial Li batteries and displays significant potential for expanding the applications in solid Li batteries.     

不同情境下老年人对健康信息源的选择差异研究

[目的/意义]揭示老年人健康信息源选择因情境不同而存在的差异,为助力图书情报机构更好地开展面向老年人的健康信息服务提供理论依据和对策建议。[方法/过程]参考信息源视野理论对信息源的分类,采用访谈法,分析老年人在处理健康危险状况、参与医疗决策、改变或预防不良健康行为这3种不同健康情境下获取健康信息的信息源选择差异,并结合人口学特征探究老年人在信息源选择数量上的群体间差异。[结果/结论]研究结果表明:(1)3种情境下,组织信息源和人际信息源均是老年人主要使用的信息源;(2)随着年龄的增长,老年人对人际信息源的依赖性逐渐增加;(3)3种情境下老年人对网络信息源、印刷信息源的使用程度都不高;(4)不同文化水平和自评经济状况的老年人群在信息源选择数量上存在明显差异,其中文化水平造成的差异在3种情境中均有体现,自评经济状况造成的差异体现在参与医疗决策和处理健康危险境况两种情境中。
