Using unanswered questions to teach John Gensic

Carol Dweck, who is now at Stanford,

conducted a research experiment

where she compared 7th graders
in two different groups.

One group, she taught study skills to,

and the other group,

they taught a mini-neuroscience class

about how their brain worked.

They followed those two groups

throughout their middle school math grades

and noticed that the group

who had the mini-neuroscience course

was much more successful
in their math grades

than the group that had
the conventional study skills,

like being organized

and using note cards.

The reason, they believe,

that the group had
the mini-neuroscience course

did so much better

is that they were picturing the formations

and the connections
in their brains occurring

while they were learning.

They were also able to have
a certain level of resilience,

knowing that their brain
was more of a muscle

and not a stone that couldn’t
grow any larger.

Having this resilience,

having students understand

that their brains can continue to grow,

allows them the confidence
to struggle with situations,

to wrestle out that information

to come to deeper understanding.

So, how does this look in my classroom?

How do I attempt to get students

to struggle with information
and wrestle with it

so they come up with deeper
levels of understanding?

Primarily, I use unanswered questions.

For example, I’ll give students a jar

and say it’s 500 grams,

and inside that sealed jar

is a moist paper towel
with about six to seven seeds.

What do you think will happen

to the mass of the container

as those seeds begin to grow?

And the students will then write

on a little half-sheet of paper

what they think is going
to happen and why.

Depending on the class,

I will have the students
sometimes work in partners

to kind of combine ideas,

see what they think
of each other’s reasons,

maybe work in groups of four

and then groups of eight

and come to consensus.

But, sometimes, I’ll have
the students pass in

all that information
without conversing about it,

and I will then read their explanations

so that they are anonymously
presented ideas

that no student can rely upon

the other smart students

to say, ‘Oh, I agree with Sally

because she’s always
got the right answer.’

That rarely happens in my class.

At this point, I will probably
stop the conversation

after I’ve read these out loud

and leave students wondering.

Wondering, what is the right answer?

What evidence is good evidence?

Because I want them,

when they leave the classroom,

to continue to want to know more,

to continue to want
to make more connections.

So, in addition to unanswered questions,

I will often pose problems and projects

for students to work on.

And, when I have them work on

these problems and projects,

I’ll give them about 15
to 20 minutes to brainstorm

how to solve the problem

or how to go about completing the project.

And this 15 to 20 minutes happens

well before I expect a lot of work

to be done on the project.

I don’t want them to try
to produce too much

because I want them to try
to figure out in their brains,

give themselves a chance

to struggle
with the information overnight,

while they go
about their daily activities.

For example, I might give a project

where you need to explain
or teach a 6th grader

the simple concept of endosymbiosis.

And the students then have

a whole bunch of questions generated

related to this project.

They have things that they need to know

from me,

from other resources.

But I have not given them

the questions and the answers to memorize,

their brain is actively seeking out

the understanding of this concept

so that they can teach it to others.

We would like to, as teachers,

think that students love
everything that we teach them,

and we think
that they understand everything

and want to engage with our content

outside of the school day.

Students don’t do that.

Most students don’t do that.

So, through mass one-way text messaging,

I’m able to resend them the question

or the topic from that day.

To get them to re-engage

and touch the content one more time.

And, hopefully, get that seed
planted in their brain

so that they want to think about it more,

so that their brains come up with

those “Ah-ha!” moments at obscure times.

My goal is for students
to generate the story,

their story,

of the content that I teach.

I would love for them

to completely understand my story

and understand it deeply,

but I know if I just get
them to understand it

as I understand it,

that will simply ooze out of their brains,

and they will not have
information and the knowledge

that is applicable in other situations.

They will not have knowledge

that they can ask more questions about.

They are simply
understanding to please me,

and then it’s gone.

“It’s not that I’m so smart,

it’s just that I stay
with problems longer.”

We, as teachers, need
to encourage and facilitate

students staying with problems longer.

Thanks.

现在在斯坦福大学的卡罗尔·德韦克(Carol Dweck)

进行了一项研究实验

,她比较
了两个不同组的七年级学生。

一组,她教学习技巧

,另一组,

他们教一个关于大脑如何工作的迷你神经科学课

他们

在整个中学数学成绩中跟踪这两个

小组

,并注意到参加迷你神经科学课程

的小组
在数学成绩上


具有常规学习技能的小组成功得多,

例如组织

和使用记事卡。

他们认为,

该小组
的迷你神经科学课程

做得更好的原因

是他们正在描绘

他们在学习时发生的大脑结构和连接。

他们也能够拥有
一定程度的复原力,

因为他们知道他们的
大脑更像是一块肌肉,

而不是一块无法
长得更大的石头。

拥有这种韧性,

让学生

明白他们的大脑可以继续成长,

让他们有信心
与各种情况作斗争,

从这些信息

中获得更深入的理解。

那么,这在我的课堂上看起来如何?

我如何尝试让学生

与信息斗争并与之
搏斗,

以便他们提出更深
层次的理解?

首先,我使用未回答的问题。

例如,我给学生一个罐子

,说它是500克

,密封罐子

里面是湿纸巾
,里面大约有六到七颗种子。

当这些种子开始生长时,你认为容器的质量会发生什么变化?

然后学生们会

在半张纸上写下

他们认为
会发生什么以及为什么会发生。

根据班级的不同,有时

我会让学生们
一起

合作,把想法结合起来,

看看他们
对彼此的看法是什么,

也许是四人一组

,然后八人一组,

然后达成共识。

但是,有时,我
会让学生在

不讨论的情况下传递所有这些信息,

然后我会阅读他们的解释,

以便他们匿名
提出想法

,任何学生都不能

依靠其他聪明的

学生说,‘哦, 我同意莎莉的观点,

因为她总是
得到正确的答案。

这在我的课堂上很少发生。

在这一点上,我可能会

在我大声朗读这些内容后停止谈话

,让学生们感到疑惑。

想知道,正确答案是什么?

什么证据是好证据?

因为我希望他们,

当他们离开教室时,

继续想知道更多,

继续想建立更多的联系。

因此,除了未回答的问题外,

我还会经常提出问题和项目

供学生研究。

而且,当我让他们处理

这些问题和项目时,

我会给他们大约 15
到 20 分钟的时间来集思广益

如何解决问题

或如何完成项目。

而这 15 到 20 分钟

发生在我期望

在项目上完成大量工作之前。

我不希望他们
尝试生产太多,

因为我希望他们尝试
在大脑中弄清楚,

给自己一个机会

在一夜之间与信息斗争,

同时他们
进行日常活动。

例如,我可能会给出一个项目

,你需要向
6 年级学生解释或教授

内共生的简单概念。

然后学生会

产生一大堆

与这个项目相关的问题。

他们有一些事情需要

从我

那里知道,从其他资源。

但是我没有给他们

记住的问题和答案,

他们的大脑正在积极寻求

对这个概念的理解,

以便他们可以把它教给其他人。

作为老师,

我们希望学生喜欢
我们教给他们的一切,我们

认为他们理解一切,

并希望在上课之外参与我们的内容

学生不这样做。

大多数学生不这样做。

因此,通过大量的单向短信,

我能够重新向他们发送当天的问题

或主题。

让他们重新参与

并再次触摸内容。

而且,希望能
在他们的大脑中种下这颗种子,

这样他们就会想更多地思考它,

这样他们的大脑就会想出

那些“啊哈!” 在默默无闻的时刻。

我的目标是让
学生产生故事,

他们的故事

,我教的内容。

我希望他们

能完全理解我的故事

并深入理解它,

但我知道如果我只是让
他们

按照我理解的方式理解它,

那只会从他们的大脑中渗出

,他们不会有
信息和

知识 适用于其他情况。

他们将不具备

可以提出更多问题的知识。

他们只是
为了取悦我而理解,

然后它就消失了。

“不是我很聪明

,只是我在
问题上停留的时间更长。”

作为教师,我们
需要鼓励和帮助

学生更长时间地解决问题。

谢谢。
