Today Tony asked our students to make up a skit to show their image of schooling. This activity provide opportunities for students to speak English and express their ideas or images of schooling which may be the first step to realize and change their own teaching perspective.

During the activities, an interesting phenomenon showed up. Most of them criticized the education they had in China. While,it was true that the Chinese education had many problems. But, the thinking and reasoning of the problematic educational phenomenon is shallow, or not deep enough, in other word, critical thinking is missing.

In order to get more from this activity, students should not jump up to conclusion too quickly. They should not ignore the context that these things took place, the social context, the historical context, the economic context, the physical context, and so on. They should also rethink the theories and rationals behind their judgement and carefully examine the proof and logic. In short, critical thinking should take the place of criticism.

Why harsh criticism of people’s own education is not good even harmful? First, it easily leads to extreme and skin deep thinking which block more intellectual endeavor. Second, it hurt their self-image and self-confidence. Third, it can easily separate their connection with the previous themselves and places. Extreme criticisms call abandon or escape but not improvement and responsibility. Try to think of place-based learning, it heals the disconnection between people and places while harsh criticism do the opposite.

According to Daniel T. Willingham, critical thinking have three key features: effectiveness, novelty, and self-direction. Critical thinking is effective in that it avoids common pitfalls, such as seeing only one side of an issue, discounting new evidence that disconfirms your ideas, reasoning from passion rather than logic, failing to support statemnts with evidence, and so on.

Critical thinking is novel in that you don’t simply remember a solution or a situation that is similar enough to guide you. Using a complex algorithm to solve a math problem is not critical thinking. But devising a new algorithm is. Critical thinking is self-directed in that the thinker must be calling the shot(making desicions themselves): awards or punishment will disrupt instead of promote critical thinking.

We have been in BC for 3days. Everything is new for our ECNU students, the beautiful campus of UBC, the long NO 44 bus, the comfortable Landmark hotel, the nice professors and staffs, the exciting learning activities.

Today is even special. We went to visit a middle school called Norma Rose Point School. The school is not far from UBC, in fact it is the neighborhood of UBC. It took us about 20 or 30 minutes to walk there from Scarfe building where our classroom located. There are about six hundreds of students in the school, from kindergarten to grade 8, including both elementary and secondary education. This school is very unique because of its educational rationals and teaching building design.

They believe learning should be integrated and take place in communities instead of separated and in classrooms of each discipline. They want to give student a whole picture of the world and want them to experience this by themselves in their learning communities. In this way, students get better understanding of who they are, where they come form, how they will change the world around them. They will also take more responsibility of their learning and be proactive to inquiry the world around them rather listen to the teacher and memorize for tests.

The learning schedule and activities are designed and carried out by a faculty team but not a single teacher as traditionally school usually do. The teacher love this kind of collaborative teaching, it also give teacher many opportunities to learn from each others. It is much easier for new teacher to join the team to teach together. As you can see, they value collaboration very much. Student collaborate with student, teachers and even parents. Teacher collaborate with colleges, parents, and university professors. Student who are good at something can teach others. Teacher can do the same thing. They are all super heroes at that time. Super hero is a learning activity designed by the 4th grade teacher team which engage students and let them rethink what a hero means.

Many features of the school building reflect educational wisdom. They make a window to let student who play basketball to look downstairs and notice what is happening in the football playground. All the classrooms are open without a door but only three or two walls. It means guests are always welcome to join or observe the class. There are also lots of art crafts made by student to show their understanding of their school spirits.

It is hard to believe such an ideal school can exist and survive. ARE there any disadvantages and challenges for this kind of school? Of course there are, but who can deny their bold spirit and unique learning place design. It is beautiful! That is enough for now!

现代人生活节奏越来越快,每个人都步履匆匆,打电话总说自己很忙,忙不过来,忙个没完没了。

这让我想起一个故事:

有一队人正在沙漠中举步维艰的前行,突然前面的队伍停了下来,首领很生气问为什么要停下来,来人回答说:我们走的太快了,要停下了等等被落在后面的灵魂。

这是一个物欲横流而缺乏反思的时代,而如果任凭自己卷入洪流就会面临迷失自我的风险。别人进城,我也进城,别人买房,我也买房,别人生娃,我也生娃,别人孩子上补习班,我也让孩子上补习班,总之千万别落后。

我是谁,我为什么要跟随,我来自哪,我要去哪里,这些人生大问题早已被紧张的城市生活所淹没。我不在是自己的我,我成了城市街道里的一个影子,不知道从哪里来,也不知道要到哪里去,忐忑而焦急,疲于奔命的紧跟着城市的节奏。

迷思概念再认识

偶然的机会发现了罗辑思维这个脱口秀节目,觉得很值得有空车上听一听。比如古典的“超级个体”概念就很启发性,下面是摘录的笔记:

一、现在是个体崛起的时代

1、知识瘫痪的人
知识碎片不能转换成个体能力,眼高手低的人。

2、白日梦想家
只是画饼,但是不思考和行动的人。

3、安全自封的人
怕承担任何分享而固步自封的人

4、错误心智模式的人
从同行是冤家到同行是伙伴
从铁饭碗到超级个体
从巨婴到巨人
从三思而后行到边想边做
从知识瘫痪到独立思考和行动
从本职工作到业余工作

现代社会:不是智者生存,也不是强者生存,而是适者生存。

现代社会的变化:
1、用很少的生活资料,就能养活自己
2、组织的寿命变短,个人的寿命变长
3、职业在跨界,公司也在跨界,跨界成了新常态

未来是个体崛起的时代,每个人生产力更强,都有机会成为想成为的自己。永远不会失业的工作没有了,只要超级个体不会失业,但是要不断换工作。

二、你需要的3种超能力

1、自我迭代:一边奔跑一般思考

2、元能力:生产、连接、传播。

3、超级复原力:经得起失败,并从失败中积累经验。

三、成为超级个体的2种心法

1、乐高式的能力组合
郝景芳的《北京折叠》获得雨果奖。单一能力结构风险很大。X型、π型人才生态位更大。

2、给自己超链接的机会
给自己跨界的机会

四、你的世界观
你相信这个世界是善意的还是恶意的?
它决定了你的认知模式和行为模式。

五、现代人的关键竞争力
学习力(阅读、倾听、联系)
生产力(生产产品)
传播力(传播观念)
领导力(合作和引领他人)
行动力(切割、计划、行动、坚持)

而这5种力,都要在独立思考和实践中发展的。

这不是一个新话题,但是却一直像幽灵一样挥之不去,影响人们的生活、健康,特别是心情。我担心它还会影响校园里孩子的身体健康,这是不可接受的,是红线。所以,现实强迫我们必须要认识雾霾、应对雾霾、治理雾霾。

一、认识雾霾
1、雾霾是什么?
雾霾,是雾和霾的组合词。雾霾常见于城市。中国不少地区将雾并入霾一起作为灾害性天气现象进行预警预报,统称为“雾霾天气”。
雾霾是特定气候条件与人类活动相互作用的结果。高密度人口的经济及社会活动排放大量细颗粒物(PM 2.5),一旦排放超过大气循环能力和承载度,细颗粒物浓度将持续积聚,此时如果受静稳天气等影响,极易出现大范围的雾霾。

气象学解释:
雾,是接近地面的空气因气温下降水蒸气凝结而成的悬浮的微小水滴;
霾,是大量极细微的干尘颗粒等均匀地浮游在空中,使水平能见度小于10千米的空气普遍浑浊现象,也称灰霾。
在气象学上,雾和霾的判识标准为:相对湿度小于80%时为霾;相对湿度大于90%时为雾;相对湿度在80%—90%之间时为雾和霾的混合物,其中雾和霾的程度要按照大气细颗粒物PM2.5和PM1.0(指空气动力学直径分别小于2.5和1.0微米的细颗粒)的浓度来判识。

值得指出的是,雾本来是一种自然现象,但是在污染导致大气细颗粒物增多的情况下,即使气象上判识为“雾”,也不再是完全的自然现象,而是有细颗粒物附着的微小水滴。

雾霾毒性大小,关键看携带的颗粒。颗粒如果是重金属就可能会导致重金属中毒,如果是致癌物质就会提升患癌症的概率。

2、雾霾是如何形成的?
从PM2.5来源看,雾霾主要是人类活动造成的。不是天灾,是人祸。
PM2.5的来源可分为一次源(直接排放)和二次源(二次生成)。

一次源又可分为自然排放源和人为排放源。其中,自然排放源包括风扬尘土、火山灰、森林火灾、海浪飞沫、生物来源等。人为排放源包括工业粉尘、机动车尾气颗粒物、道路扬尘、建筑施工扬尘、厨房烟气等。

二次生成是指排放到大气中的气态污染物通过多种化学物理过程产生的二次细颗粒物。人类活动排放的大量气态污染物如二氧化硫SO2、氮氧化物NOx、氨气NH3、挥发性有机污染物(VOCs)等,都能在大气中被氧化产生硫酸盐、硝酸盐、铵盐和二次有机气溶胶(SOA)。这些新生成的细颗粒物是大气中PM2.5的重要来源。全球范围内,二次颗粒物贡献率在20%—80%之间,在我国中东部地区常常高达60%,在成霾时往往二次颗粒物所占比例更高。

也就是说,人类活动产生的二次颗粒物占比更高!从这个意义上说,雾霾主要是人类活动造成的。

3、雾霾的危害有哪些?
危害人体健康,特别是呼吸器官。

妨碍交通出行,提升安全隐患。

4、关于雾霾的谣言?
谣言一:只要戴口罩就能防雾霾?
谣言二: 空气净化器可以有效净化雾霾,家中必备?
谣言三:防雾霾中医药方、多吃蔬菜能防雾霾?
谣言四:雾霾是“核雾染”?
答案: 点击这里

二、防护雾霾
1、户外活动如何防护?

2、室内活动如何防护?

3、如何调节个人活动达到防护的目的?

三、治理雾霾:从个体到社会,从科学到艺术,从产品到市场。
1、个人选择:从环保意识到生活习惯。
2、商业经济:如何让雾霾有利可图?
3、公共政策:让谁来买单?
4、产品研发:从口罩到空气净化机的设计。
5、科研工程:谁来把雾霾吹走?
6、文化艺术:神曲,还是神曲,没有话剧?

我的系统是win7,有一个问题一直困扰着我,就是每次打开word文档的时候总是第一次失败,第二次正常。

今天网上找到一个方法,就是把默认输入法从搜狗输入法改成中文简体美式键盘。

在用不用打开两次那么麻烦了。

魔镜魔镜告诉我,什么知识最重要?

拉丁文吗?科学吗?经典著作吗?文化要素吗?关于如何学习的知识吗?问题解决能力吗?核心素养吗?创造力吗?STEM吗?……

这个世界变化太快,生活变化太快,我们真的能教给学生足以应对未来挑战的东西吗?假如这个东西是存在的?那么它是什么?它是不变的还是变化的?如果它是不变的,那么它如何帮助学生应对从未有过的新挑战?如果它是变化的,那么寻求不变的传承或者最核心的知识、技能是否就要落空?对于这个不断变化的东西,我们怎么掌握它变化的规律,怎么去描述它,怎么在教学实践中实现它,让学生经过有限时间的培养长出它的果。

当下,核心素养成为一个红得发烫的标签,就好像以前提的素质教育,还有人人都说的“以学生为中心”的口号,以最快的速度在媒体、报纸、学术杂志泛滥开来。其实之所以有这样的提法,跟我们的时代背景密切相关。现在时信息时代,信息爆炸,知识也跟着泛滥,我们突然意识到,不可能把所有有用的知识、技能都传承下去,那么至少传承最重要的,最有用的,最核心的,核心素养就在这样的背景中粉墨登场的。其实这不是一个新问题,但是人么确实是史无前例的感觉到了这个问题的迫切性,进而试图用核心素养来解决这个难题。

当然,一个标签是解决不了任何问题的,所以我们要弄清楚核心素养的内涵。21世纪核心技能包括:学习与创新技能、生活与职业技能、信息媒体与技术技能。OECD则要测查世界不同地区15岁青少年是否为未来生活做好了准备,并将科学素养定位为反思性公民参与公共科学相关议题讨论和实际问题解决的能力。在其测评中,以科学地诠释现象、设计和评价科学探究、科学地阐释资料和证据三个维度测评青少年的科学素养。再有就是流行的4Cs,交流-合作-批判性思考-创造(Communication, Collaboration, Critical thinking and Creativity)。就这些组织和机构提供的答案来看,核心素养并不是一个有明确内涵的统一概念,它实际上是培养目标的一种抽象而笼统的表达。这样一来,这个标签的内涵自然是变化的,而且不同国家、不同时期其相应的内涵也会有差异。所以提核心素养,就是再提培养目标,当然它与全面发展有些小矛盾,因为全面发展更理想化,而在有限时间和资源条件下,提核心素养可能更实际,但是同时我们也要注意不要把不该削减的削减了,那就真的把核给扔了,变成无心素养了。

我们找不到问题的答案,有时是因为思维方法不对,有时却因为问题本身就有问题。

教学是不是一种知识传承?教学是不是只是一种知识传承?

教学过程中必然有知识传承,但是期望这种传承直接帮助学生应对外来挑战,那是太乐观了。

教学肯定不仅仅是一种知识传承,实际上它是一种师生合作再造、再发现,学生的学习成果一方面是已有的知识和技能,另一方面是学生和教师合作过程中生成性成长。
