一般说来,“教师”概念之形成经历了十分漫长的历史。
杨士勋(唐初学者,四门博士)《春秋谷梁传疏》曰:“师者教人以不及,故谓师为师资也”。
这儿的“师资”,其实就是先秦而后历代对教师的别称之一。
《韩非子》也有云:“今有不才之子……师长教之弗为变”其“师长”当然也指教师。
这儿的“师资”和“师长”可称为“教师”概念的雏形,但仍说不上是名副其实的“教师”,因为“教师”必须要有明确的传授知识的
对象和本身明确的职责。
小亮做减法,错把减数24写成26,结果是14,那么正确的差是( ).
与当今“教师”一称最接近的“老师”概念,最早也要追溯至宋元时期。
金代元好问《示侄孙伯安》诗云:“伯安入小学,颖悟非凡貌,属句有夙性,说字惊老师。
”于是看,宋元时期小学教师被称为“老师”有案可稽。
清代称主考官也为“老师”,而一般学堂里的先生则称为“教师”或“教习”。
可见,“教师”一说是比较晚的事了。
如今体会,“教师”的含义比之“老师”一说,具有资历和学识程度上较低一些的差别。
辛亥革命后,教师与其他官员一样依法令任命,故又称“教师”为“教员”。
家庭是幼儿语言活动的重要环境,为了与家长配合做好幼儿阅读训练工作,孩子一入园就召开家长会,给家长提出早期抓好幼儿阅读的要求。
我把幼儿在园里的阅读活动及阅读情况及时传递给家长,要求孩子回家向家长朗诵儿歌,表演故事。
我和家长共同配合,一道训练,幼儿的阅读能力提高很快。
