3Generalrequirementsfortheperformanceevaluation
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。
3.1Responsibilitiesandresources
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。

单靠“死”记还不行,还得“活”用,姑且称之为“先死后活”吧。
让学生把一周看到或听到的新鲜事记下来,摒弃那些假话套话空话,写出自己的真情实感,篇幅可长可短,并要求运用积累的成语、名言警句等,定期检查点评,选择优秀篇目在班里朗读或展出。
这样,即巩固了所学的材料,又锻炼了学生的写作能力,同时还培养了学生的观察能力、思维能力等等,达到“一石多鸟”的效果。
