【摘 要】《幼儿园教育指导纲要》明确指出：“幼儿的空间、设施、活动材料和常规要求等应有利于引发、支持幼儿的游戏和各种探索活动，有利于引发、支持幼儿与周围环境之间积极的相互作用。” 我们的幼儿园地处农村，有着丰富的自然资源，是全国有名的花木之镇，我们最优越的环境就是花草树木、大自然，因此，因地制宜，发挥农村特色，充分利用农村自然环境资源，将幼儿关注的、感兴趣的身边素材运用到幼儿园的活动中，提高幼儿的
【摘 要】在对幼儿的教学中游戏教学是一种十分有效的教学方式，不仅能够让幼儿在游戏中获得较多的知识，而且还能够有效培养幼儿的想象力和创造力，对幼儿的成长有着较大的帮助，而利用农村自然资源来丰富幼儿游戏，更能够有效调动学生学习的积极性，并让教学与实际生活联系起来，有助于幼儿的成长。本文主要对如何利用农村自然资源丰富幼儿游戏展开研究。 【关键词】农村自然资源；幼儿游戏；实践研究 利用幼儿游戏进行教学
Polymer semiconductors have aroused interests from both academic and industry due to their wide applications in electronic devices,such as organic thin-film transistors(OT-FTs)[1],polymer solar cells(PSCs)[2−6],organic thermoelectrics(OTEs)[7−11],and pero
p-Benzoquinone(BQ)is a promising candidate for next-generation sodium-ion batteries(SIBs)because of its high theoretical specific capacity,good reaction reversibility,and high resource availability.However,practical application of BQ faces many challenges
Anion-immobilized solid composite electrolytes(SCEs)are important to restrain the propagation of lithium dendrites for all solid-state lithium metal batteries(ASSLMBs).Herein,a novel SCEs based on metal-organic frameworks(MOFs,UiO-66-NH2)and su
Wide-bandgap copolymer donors with fused-ring accept-or units(FAUs)present excellent performance in non-fullerene organic solar cells due to their complementary light-absorption with nonfullerene acceptors,deep the highest occupied molecular orbital(HOMO)
White light emitting diodes from a single emitter is of sig-nificance in application of illumination and image display be-cause of avoiding the color instability in devices with mul-tiple emitters[1,2].Recently,as a single emitter,low-dimension-al halide
As containing earth-abundant elements,kesterite(Cu2Zn-Sn(S,Se)4,CZTSSe)semiconductors have great potential to be low-cost and environmental-friendly inorganic absorbers.However,the record power conversion efficiency(PCE)for CZTSSe so
Since Geim et al.firstly separated graphene from graph-ite by mechanical exfoliation method in 2004,the research of two-dimensional(2D)van der Waals(vdW)layered materials has begun[1].Compared with three-dimensional materials,2D vdW layered materials expo
