工场教员与三种工场教授法     

W.T.B  秦翰才 《教育与职业》1924,(0)

教授为各种教员之主要业务.工场教员自亦不在例外.惟工场教员如实验室科学教员.尤须负组织及经理之责.盖工场之设备.少则值数百圆.多则达数千数万圆.是其保管维护.均工场教员一身.万一失于捡贴.势必损坏而失其效用.故为工场教员.须谨慎精细.同时工场教师亦为购货主任.凡工场所需之工具.材料等等.均应由工场教员随时调查.供给支配.此亦须特殊之知识与能力者也.于是我人  相似文献   

红木树——数学与自然

自然总是让人大吃一惊.当我们仔细看看自然界的各个领域,便会得出这样的结论:自然似乎懂得数学!那高高的海岸红木,那巨大的加利福尼亚美洲杉,都是地球上最古老的活在世上的东西.在它上面我们能够发现一些诸如同心圆、同心圆柱、平行  相似文献   

Multiscale fabrication of a transparent circulation type blood vessel simulator     

Nakano T  Itoyama T  Yoshida K  Sawada Y  Ikeda S  Fukuda T  Matsuda T  Negoro M  Arai F 《Biomicrofluidics》2010,4(4):46505

We proposed and fabricated multiscale transparent arteriole and capillary vessel models with circular cross sections of 10-500 μm using photolithography. The circularities of the fabricated 10, 50, and 500 μm diameter microchannels were 84.0%, 61.5%, and 82.3%, respectively. Next, we connected these different models to realize a circulation type blood vessel model simulating arteriole networks. We proposed a novel connection method using an intermediate connector made of wax, which we used to connect these models to make a circulation model. In flow experiments, the fabricated models showed no leakage and circulation models with seamless connections were achieved.  相似文献   

如何开展家长培训     

Barbara T.Doyle  汤素梅 《现代特殊教育》2007,(7):78-78

残障儿童的父母．是孩子一生最好的教育者，因为他们在孩子成长的过程中无私奉献，恪尽责任。对那些有残障儿童的家庭而言．“知识就是力量”这句话就是真理。这些家长需要掌握关于残障症状的特点、教育治疗方案和策略等信息，以提升日常生活质量。家长们也想知道什么样的服务最适合孩子．如何获得这些服务．如何定位家长角色以确保孩子的进步．[第一段]  相似文献   

Developmental links of very early phonological and language skills to second grade reading outcomes: strong to accuracy but only minor to fluency     

Puolakanaho A  Ahonen T  Aro M  Eklund K  Leppänen PH  Poikkeus AM  Tolvanen A  Torppa M  Lyytinen H 《Journal of learning disabilities》2008,41(4):353-370

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.  相似文献

Approaching sign language test construction: adaptation of the German sign language receptive skills test     

Haug T 《Journal of deaf studies and deaf education》2011,16(3):343-361

There is a current need for reliable and valid test instruments in different countries in order to monitor deaf children's sign language acquisition. However, very few tests are commercially available that offer strong evidence for their psychometric properties. A German Sign Language (DGS) test focusing on linguistic structures that are acquired in preschool- and school-aged children (4-8 years old) is urgently needed. Using the British Sign Language Receptive Skills Test, that has been standardized and has sound psychometric properties, as a template for adaptation thus provides a starting point for tests of a sign language that is less documented, such as DGS. This article makes a novel contribution to the field by examining linguistic, cultural, and methodological issues in the process of adapting a test from the source language to the target language. The adapted DGS test has sound psychometric properties and provides the basis for revision prior to standardization.  相似文献   

博物馆之夜     

M·T·考弗因  唐兵 《故事作文(高年级版)》2004,(1)

夜闯博物馆我顿了顿,等侍者拿走菜单,才开口:“如果我们偷偷溜出旅馆,自己去博物馆,一定会出事的。”“不,不会的,托尼。”贾尼丝说,“我查过了,博物馆礼拜六晚上通常九点关门,我们只要赶在去看音乐剧的卡尔森小姐和其他同学回来之前回到旅馆就行了。”“来得及吗?”我有点担心。“这次作业我必须拿个好分数。”贾尼丝说,“否则,他们会把我从尖子班开除的。”“我也是。”贾森附和道,“上次我收集的资料不够,起码得再去一趟。”他们全都盯着我。点了点头:“好吧,反正我也要花更多的时间画我的动物草图,那些图要用在论文里。不过,在走之前,我…  相似文献   

市场的认识及选择     

理查德·T·海斯  乔洪生 《呼兰师专学报》1994,(2)

选择目标消费者对公司商务的能否成功至关重要,这个问题也颇为复杂.说它重要,是因为任何市场计划的成功与否关键都在于行销人员是否能够准确地认定顾客的需求,并选择那些特定的最有利可图的对象去提供服务.说它复杂,是因为市场环境千变万化,某些重要的市场特征复杂多样,常常不易权衡.本章和下一章的中心任务就是要描绘某些重要的市场特征.观察这些特征如何变化,并深入探讨这些市场特征如何影响顾客的购物决策及行销管理.本文将描绘一下各种顾客.要明确顾客的购物动机会非常困难,通常需要对消费动机进行广泛调查.下一章将探讨消费活动中的一些“为什么”.  相似文献
