Learning Curves

(2012-10-04 07:18:07) 下一个


Today, when I woke up so early in the morning, I decided to write this down. I record it for myself, my son, my nieces and nephews, and family and friends.

Rather than an asymptotic line as told by those advance learners when I started to seriously learn English, as shown in yellow in the above graph, I followed a symmetric one as the black line shows. The 4~5 years measure is for language learning, and it would be shortened to about 1/10 of it if it were to learn something new in or close to my own field.

I was to "kill the enemies one by one" when I decided to work on my language skills a little more than 4 years ago. The first target I picked was accent. I thought I could get it right in about 2 years -- 1 at best and 3 in the worst case, and then I could focus on expressing skills. Now four years has passed, and I still speak Chinglish even in terms of only pronunciation. However, to my surprise, things have finally started to pick up, not only in pronunciation, but also in expression. In the meantime that my ears started to really tell the phonetic sounds, those words that I had looked into dictionaries for tens and hundreds of times but still left no trace in my memory started to show up more and more often when I needed them, appearing first vaguely and then clearer and clearer.

The other day I shared on the forum my parking lot adventure. Not many paid attention to it though, it actually made me think a lot. I realized that learning could never enter the same track as that mission impossible (unless reverse and back out completely) situation as shown in the below graph. The true efforts one has paid would never end up in vain, as long as she doesn't give up too early. I admit it does take guts to do so though. I am not a hardworking nor a persistent person. But now I proved it to myself that I do have the confidence that I need in myself, ignoring what kind of situation I am in, and to the very few things that I really care, I am determined to some degree of stubburnness. Oh, yes, and now I am proud of being so. :-)

我非常赞同sportwoman 九月八号在论坛上分享的下面这篇文章的观点,它跟我自己及家人的学习经历吻合。

如何进行中学语文教学

 

张朝鑫

 

中学语文课不好上,中学语文课难上,难道什么程度呢 ?用当地的话讲:“语文课难上,就像漂流黄河长江。”什么意思,就是说,语文中的学问就像长江黄河一样博大精深。学生如何在这滚滚奔流的江水中舀到属于自己的“一碗水”或“一盆水”或“一桶水”,那就要看教师这个“领航人”是如何带领学生这些“旱鸭子”,由“落汤鸡”变成“水上漂”的。本文对此作一点浅论。

 

一、语文课堂教学是教师和学生共同创建的教学美

 

语文教学,教师就像带领学生在长江黄河上漂流。教师作为“漂流队”的导航人,必须具有搏击风浪、迎急流、跨险滩的本领,才能驾轻就熟地越过重重障碍,在飞流直下的江河里等闲航行。

 

对学生来讲,光靠领航人指路是不行的,还必须亲自驾舟涌进江水,接触急流,与风浪搏击。既然是“漂流”,那就必须具备其基本要领技术。除了驾驭江水的本领外,还必须对长江黄河有一个整体感知。漂流长江黄河,最难的是上游,其技术要求高,因为上游山高水急、落差最大、危险最多。若不熟悉基本情况,就可能一涉水就成“千古恨”——“水好深啊!好冷啊!好怕呀!太难了!”再也不想“漂”了。然而只要漂过了上游,就是一马平川,以后的航程就足可“任凭风吹浪打,胜似闲庭信步”了。(《毛泽东诗词·游泳》)

 

语文教学也是如此,教师如何带领学生在语文的江河中漂流呢?学生必须要积累有基本技能、基本知识,教师必须带领学生到“三江源头”去查地形、看水情、观急流、算落差,然后驾舟入江亲自去整体感知。教师要运用一定的手段再创造,让学生自己“漂”、与学生一起“漂”。而不能“隔岸官火”、坐阵指挥。也就是说,语文教学是教师和学生共同创造的教学美。在这个过程中,学生就会在教师的指导下生动活泼地发现、创造、享受语文教学中的美感。这是很美的事。如果学生不参与这个过程,他就得不到成功的快乐,当然也读不懂书。在这个过程中,教师必须让学生自己“漂”,不能“以讲代漂”“只讲不漂”。这“漂”就是读书——学生自读课文。读书就是积累基础知识、基本技能,如果把“漂流”说成是整体感知江水,那么读书就是整体感知课文,提高阅读能力。教师要根据课文的重点、难点帮助编出自读提纲——思考题,这就像“漂流航行图”给学生以指导。这很重要,要在“漂流”——阅读前进行,先下手为强。http://blog.people.com.cn/open/articleFine.do?articleId=1313975022990

整体感知即整体阅读:先朗读后默读。朗读重在读出感觉,默读重在读出思考。学生从整体阅读中感知课文的内容、观点、倾向和作者的感情,从整体上把握住课文的感情基调是悲伤?喜悦?激动?平静?就像“漂流”中感知江水的急、缓、冷、暖、清、浊一样。

 

在整体感知的基础上,学生按照教师的“漂流图”——思考题,独立思考解决问题——自己“漂”。哪些问题解决了?哪些问题还没有解决?又遇到什么新问题不能解决?教师要安排时间让学生质疑,这一点太重要了,就像“漂流”了一段江水后必须总结,为以后的继续“漂流”积累经验。教师必须以其渊博的知识,娴熟的手法充分调动学生自己解决问题的积极性,与学生联手创造教学美。

 

当然教师总得放手让学生自己“漂”,以检测学生阅读的效果。这就是学完一篇课文后的测试,以检测教学效果(不一定就是考试,也可以运用课堂质疑的方式)。测试的导向是促使学生一手抓基础知识,一手抓书写、拼音、词语、标点等等,重在活用。虽然这些都是小学语文教学中的环节,在中学阶段仍然不能放松。因为小学积累的基础知识仅相当于在“漂流”前到“三江源头”去看了一看“涓涓细流”,还不具备漂越“虎跳峡”、冲过黄河“壶口瀑布”的能力,还不能活用。所以两手都要抓,两手都要硬。

 

至于段落分析不是不要,它的作用不仅在于理解段落本身,更重要的是用来验证整体阅读感觉是否正确,就像“漂流”过一段江水后回过头来望一望,回味一下“漂流”的感觉如何。

 

语文教学不外是提高学生的阅读能力——口头表达能力和写作能力(后面另有论述)。整体感知阅读对于口头能力的表达有极大的帮助,但是这只是一个量的积累,要把语言重新变成纸上文字这是一个质的飞跃,必须加强训练。爱写作的人都有这样的感受:口上说得头头是道的话,再写到纸上时总觉得表达不清,甚至自相矛盾。话说完就消失了,写在纸上的文章是要给别人看的,写作在语文教学中太重要了,这是语文教学的最根本的目的。因此每学完一课或一个单元,必须写一个类似的作文,作为“漂流”的指导者的教师,同样要写一篇“下水 ”作文— —范文,不然,你只讲不写,以讲代写,你“只在岸上走,漂流不湿鞋”,学生就可能“将”你“军”:“教练你看这水急浪涌,到底该怎样漂?你先漂一段给我们看一看吧。”因此语文教学始终是一个教师与学生共同参与,并且以学生为中心的过程,就像“漂流”指挥始终与漂流队员在一起,并且以漂流队员为中心一样。
