QUESTION151

“教书先生”恐怕是市井百姓最为熟悉的一种称呼，从最初的门馆、私塾到晚清的学堂，“教书先生”那一行当怎么说也算是让国人景仰甚或敬畏的一种社会职业。

只是更早的“先生”概念并非源于教书，最初出现的“先生”一词也并非有传授知识那般的含义。

《孟子》中的“先生何为出此言也？

”；《论语》中的“有酒食，先生馔”；《国策》中的“先生坐，何至于此？

”等等，均指“先生”为父兄或有学问、有德行的长辈。

其实《国策》中本身就有“先生长者，有德之称”的说法。

可见“先生”之原意非真正的“教师”之意，倒是与当今“先生”的称呼更接近。

看来，“先生”之本源含义在于礼貌和尊称，并非具学问者的专称。

称“老师”为“先生”的记载，首见于《礼记?

曲礼》，有“从于先生，不越礼而与人言”，其中之“先生”意为“年长、资深之传授知识者”，与教师、老师之意基本一致。

唐宋或更早之前，针对“经学”“律学”“算学”和“书学”各科目，其相应传授者称为“博士”，这与当今“博士”含义已经相去甚远。

而对那些特别讲授“武事”或讲解“经籍”者，又称“讲师”。

“教授”和“助教”均原为学官称谓。

前者始于宋，乃“宗学”“律学”“医学”“武学”等科目的讲授者；而后者则于西晋武帝时代即已设立了，主要协助国子、博士培养生徒。

“助教”在古代不仅要作入流的学问，其教书育人的职责也十分明晰。

唐代国子学、太学等所设之“助教”一席，也是当朝打眼的学官。

至明清两代，只设国子监（国子学）一科的“助教”，其身价不谓显赫，也称得上朝廷要员。

至此，无论是“博士”“讲师”，还是“教授”“助教”，其今日教师应具有的基本概念都具有了。

要练说，得练看。

看与说是统一的，看不准就难以说得好。

练看，就是训练幼儿的观察能力，扩大幼儿的认知范围，让幼儿在观察事物、观察生活、观察自然的活动中，积累词汇、理解词义、发展语言。

在运用观察法组织活动时，我着眼观察于观察对象的选择，着力于观察过程的指导，着重于幼儿观察能力和语言表达能力的提高。
