教研、教科研、教师培训作为县域中小学教师专业引领的主要路径,其统合综效的不完善引发了我们对研训生态的关注,这三项职能工作能否通过一个更好的秩序来促进整体工作能效的提高?教研主题化、主题课题化、课题课程化、课程系列化就是基于这一思考与实践建立的县域生态研训机制,期待这一机制能力促科研、教研、师训工作从形式存在走向生态关系,发挥机制效应,更好地服务教育教学。 相似文献

Mechanical model of domestic gas explosion load 总被引：3，自引：0，他引：3
With the increase of domestic gas consumption in cities and towns in China,gas explo-sion accidents happened rather frequently,and many structures were damaged greatly.Rational physical design could protect structures from being destroyed,but the character of explosion load must be learned firstly by establishing a correct mechanical model to simulate vented gas explo-sions.The explosion process has been studied for many years towards the safety of chemical in-dustry equipments.The key problem of these studies was the equations usually involved some ad-justable parameters that must be evaluated by experimental data,and the procedure of calculation was extremely complicated,so the reliability of these studies was seriously limited.Based on these studies,a simple mathematical model was established in this paper by using energy conservation,mass conservation,gas state equation,adiabatic compression equation and gas venting equation.Explosion load must be estimated by considering the room layout; the rate of pressure rise was then corrected by using a turbulence factor,so the pressure-time curve could be obtained.By using this method,complicated calculation was avoided,while experimental and calculated results fitted fairly well.Some pressure-time curves in a typical rectangular room were calculated to inves-tigate the influences of different ignition locations,gas thickness,concentration,room size and venting area on the explosion pressure.The results indicated that: it was the most dangerous con-dition when being ignited in the geometry centre of the room; the greater the burning velocity,the worse the venting effect; the larger the venting pressure,the higher the peak pressure; the larger the venting area,the lower the peak pressure. 相似文献

小学语文课程标准中提倡积极主动、合作探究的学习方式。它不仅能够全面培养学生的人文素养、创新意识,还可以提高实践能力。此种方式主要是指学生在教师的指导下,以学生为主体,充分发挥小组学习、全班学习的群体作用,在合作中学习运用语言文字,培养学生主动探究、团结协作、勇于创新的学习精神。 相似文献

素质教育的今天,教师的心理健康也逐步进入了人们的视野。关于教师职业倦怠感的研究层出不穷,而针对各学科教师倦怠感成因的具体研究却少之又少。语文教师职业倦怠的产生主要因三种冲突而起：语文课堂的开放性与试卷评价的标准性;教师教学的艰巨性和学生目的的功利性;专业素养要求的宽泛性和自身能力水平的有限性。语文教师应坚守大语文教学观、灌输正确的语文学习观,并有效协调、和悦身心,方能缓解或防治自身的职业倦怠。 相似文献
