Reviewer Gopalco Is there anything more important than how well we can think?
0:00.02 – 0:25.18 (25.2s)
2
If you don't think so, then I'd ask you to think about the fact that you just had to think that.
0:26.40 – 0:31.66 (5.3s)
3
As we look around the world today at the many serious problems that we're facing, serious problems of war and climate change and untold political strife, I don't think I'm the only one who's noticed, as well as the very real problems we face in our personal lives and the problems that our children will face, is there anyone who thinks that this is a problem of too much critical thinking?
0:34.14 – 0:57.68 (23.5s)
4
Anyone?
0:58.68 – 0:59.24 (0.6s)
5
Anyone?
0:59.96 – 1:00.50 (0.5s)
6
Bueller?
1:01.04 – 1:01.94 (0.9s)
7
Bueller?
1:01.36 – 1:03.34 (2.0s)
8
I don't think so either.
1:02.36 – 1:06.06 (3.7s)
9
And that's why in 2011, I founded the country's first academic office specifically devoted to the teaching of critical thinking and why I eventually founded the Critical Thinking Institute.
1:05.36 – 1:16.80 (11.4s)
10
I set myself what was a rather humble challenge, a simple ambition, if you will.
1:16.36 – 1:22.34 (6.0s)
11
All I wanted to do was figure out how to teach everybody in the world how to think critically.
1:21.36 – 1:27.14 (5.8s)
12
Yeah, I know.
1:28.10 – 1:28.66 (0.6s)
13
That's it.
1:28.66 – 1:29.22 (0.6s)
14
I also have other humble ambitions.
1:30.26 – 1:32.34 (2.1s)
15
I like tilting at windmills and someday think the New York Giants might win another Super Bowl.
1:32.12 – 1:37.78 (5.7s)
16
But that was my goal.
1:39.64 – 1:40.64 (1.0s)
17
I wanted to teach everybody how to think critically, from kids through teens to adults, through kindergartens and college classrooms and corporate boardrooms.
1:40.36 – 1:48.62 (8.3s)
18
So what is this thing that we call critical thinking?
1:49.80 – 1:52.38 (2.6s)
19
Well, this is just a short list of all the things that critical thinking is.
1:52.82 – 1:57.84 (5.0s)
20
or in fact, this is just half a short list of all of the things that critical thinking is.
1:58.22 – 2:03.34 (5.1s)
21
And I'm sure that all of you could make meaningful additions to this list because it goes on and on and on.
2:03.26 – 2:10.28 (7.0s)
22
With that being the case, how in the world can we teach a human being to do all of these different things well?
2:11.52 – 2:17.82 (6.3s)
23
Well, before we get to that, let's see, how well are we doing with critical thinking?
2:19.66 – 2:24.62 (5.0s)
24
Well, the Stanford History Education Group did a study of how well teens could think critically while they were online.
2:25.42 – 2:32.10 (6.7s)
25
Their conclusion, and I quote, young people's ability to reason about information they see on the internet can be summed up in one word, bleak.
2:31.98 – 2:42.38 (10.4s)
26
Don't kill the messenger.
2:44.12 – 2:45.64 (1.5s)
27
And the Wall Street Journal, upon surveying critical thinking outcomes of college students, to the following rather stark conclusion.
2:46.82 – 2:56.24 (9.4s)
28
Even at some of the most prestigious flagship universities, test results indicate the average graduate shows little or no improvement in critical thinking over four years.
2:56.24 – 3:09.66 (13.4s)
29
I know.
3:09.66 – 3:12.42 (2.8s)
30
And if you want to see just how bad it gets, when researchers had college students wear portable brain monitoring devices for a week, they found as you would expect varying degrees of brain activity depending upon what the students were doing, whether they were studying or eating a meal or socializing.
3:12.42 – 3:31.46 (19.0s)
31
But the place they consistently found some of the least brain activity was when students were in class.
3:31.46 – 3:38.30 (6.8s)
32
I'm sure that's a wonderful statistic for any of you who are some who are currently putting someone through college.
3:38.30 – 3:45.60 (7.3s)
33
So I want to find out why.
3:45.60 – 3:49.52 (3.9s)
34
Why are our critical thinking outcomes so low?
3:49.52 – 3:52.30 (2.8s)
35
And I cannot begin to enumerate for you all of the problems we found with our critical thinking instruction.
3:52.30 – 3:58.66 (6.4s)
36
It would take far too long.
3:58.66 – 4:01.00 (2.3s)
37
I need a lot of TED Talks to accomplish that.
4:01.00 – 4:03.82 (2.8s)
38
But I can share with you our number one reason.
4:03.82 – 4:08.04 (4.2s)
39
Something that no one had solved for and something that challenged us in what turned out to be a a decade-long project.
4:08.04 – 4:15.52 (7.5s)
40
We refer to it as the sandbox problem.
4:16.82 – 4:19.44 (2.6s)
41
See, even in the simplest of sandboxes where we have children playing, there are an array of complex, critical thinking tasks at work.
4:19.70 – 4:26.96 (7.3s)
42
Well, who's going to get the shovel?
4:27.68 – 4:29.28 (1.6s)
43
How are we going to get this sand out of our shoes?
4:29.92 – 4:32.98 (3.1s)
44
How do we get this other kid to stop throwing sand in everybody's face?
4:33.68 – 4:36.56 (2.9s)
45
What game should we invent?
4:37.28 – 4:38.48 (1.2s)
46
What should the rules be?
4:38.88 – 4:39.82 (0.9s)
47
And why again is it that we're not allowed to play in the yellow sand?
4:40.32 – 4:43.64 (3.3s)
48
And that's just the simplest of sandboxes in which we begin not the metaphoric sandboxes of our lives, sandboxes that obviously become infinitely more complex as we enter adulthood and grapple with the challenges of the real world.
4:45.40 – 5:01.30 (15.9s)
49
In fact, as we take a look at our list of critical thinking skills and we overlay our sandbox on top of it, we find so many of these already present in the simplest of sandboxes.
5:03.74 – 5:14.82 (11.1s)
50
Well, they're problem solving, perhaps about how to move the sand.
5:15.12 – 5:18.38 (3.3s)
51
They're innovating games and ideas.
5:18.30 – 5:20.80 (2.5s)
52
They're arguing, perhaps, over who gets the shovel in this case.
5:20.56 – 5:24.28 (3.7s)
53
They're inquiring about what other kids think they should do and why.
5:23.96 – 5:28.74 (4.8s)
54
And the list could go on and on.
5:28.40 – 5:30.46 (2.1s)
55
So the sandbox problem for us became as this.
5:31.60 – 5:34.32 (2.7s)
56
Given the complexity of even the simplest sandbox, of all of the critical thinking acts that are taking place, and even the simplest sandbox among kids, How do we simplify the teaching of critical thinking enough so that everyone in the world can learn it easily without undermining the complexity of critical thinking itself, the complexity that we see in even the simplest of sandboxes?
5:34.94 – 6:00.50 (25.6s)
57
Well, that challenged us for years.
6:03.24 – 6:05.96 (2.7s)
58
And whatever research we did, we couldn't find anyone to our satisfaction had solved for this sandbox problem.
6:06.64 – 6:12.44 (5.8s)
59
simplifying the teaching of critical thinking without undermining the complexity of critical thinking.
6:12.98 – 6:18.26 (5.3s)
60
Well, then I had an idea.
6:20.18 – 6:21.46 (1.3s)
61
It occurred to me that if we were ever going to solve the sandbox problem, we would only be able to do so if we relied on how the human brain evolved to think in the first place.
6:21.70 – 6:34.70 (13.0s)
62
Instead of contriving some conception of critical thinking and then trying to get brains to do it, What if, instead, we figured out how the brain was designed to function?
6:35.70 – 6:47.38 (11.7s)
63
We looked at its most basic operating system, and we built a critical thinking system on that.
6:47.68 – 6:54.92 (7.2s)
64
To figure out how the brain was designed to function, to understand its most basic operating system, the system that's operating no matter where we are and what we're doing, the system that is operating as you're listening to me right now, we had to trace back the origin of how the human brain evolved to think critically.
6:55.58 – 7:13.62 (18.0s)
65
And when I say, we traced it back, I mean we traced it back pretty far.
7:13.66 – 7:18.98 (5.3s)
66
To primordial ooze.
7:20.42 – 7:21.90 (1.5s)
67
This is an actual picture of primordial ooze from billions of years ago, by the way.
7:23.04 – 7:26.24 (3.2s)
68
So we traced it back to primordial ooze.
7:27.68 – 7:29.50 (1.8s)
69
Because what evolutionary biologists tell us is that from the moment Single-celled organisms came to life in that ooze.
7:29.16 – 7:37.32 (8.2s)
70
They were already capable of four thinking acts.
7:36.74 – 7:40.80 (4.1s)
71
Four thinking acts that are the foundation for all of the more advanced critical thinking that we're able to do today.
7:40.86 – 7:47.12 (6.3s)
72
Quoting neuropsychologist Stephen Hughes, those four acts are as follows.
7:49.04 – 7:53.58 (4.5s)
73
They could perceive their environment, sense danger and reward, decide between danger and reward, and act on the decision.
7:53.64 – 8:04.52 (10.9s)
74
In essence, simply put, what's going on around me?
8:05.26 – 8:08.42 (3.2s)
75
What's out there that I might want to eat?
8:09.04 – 8:10.72 (1.7s)
76
What's out there that might want to eat me?
8:11.20 – 8:13.34 (2.1s)
77
How do I weigh some of those pros and cons, and how do I ultimately act upon the decision?
8:14.02 – 8:18.42 (4.4s)
78
You've already been through this same process thousands of times already today.
8:19.70 – 8:24.46 (4.8s)
79
You did it when you decided what to have for breakfast.
8:24.08 – 8:27.14 (3.1s)
80
There are an array of choices available to you in your environment that you surveyed.
8:27.58 – 8:31.30 (3.7s)
81
You weighed some pros and cons about different things in terms of their health benefits, perhaps, or how they tasted and what mood you were in.
8:32.06 – 8:38.08 (6.0s)
82
You made some decisions and put some things on your plate, and then you ate your breakfast.
8:38.96 – 8:42.92 (4.0s)
83
You did it hundreds of times if you drove here today, whether or not to change lanes, how fast to go, where to park.
8:42.58 – 8:49.35 (6.8s)
84
And we do it when we make even the most high-stakes decisions in our lives, well, decisions around parenting and our children, career choices, and what we do in our careers every single day.
8:49.97 – 9:01.09 (11.1s)
85
So that is the most basic function that's operating in our brains all of the time.
9:03.09 – 9:08.57 (5.5s)
86
And the question became, would it be possible to convert that into a system for critical thinking?
9:09.41 – 9:17.01 (7.6s)
87
Would that solve the sandbox problem?
9:17.29 – 9:20.41 (3.1s)
88
Would it simplify critical thinking enough so that everybody could learn it while maintaining the rich complexity that we need critical thinking to be to contend with the rich problems we're facing in the world?
9:20.41 – 9:31.29 (10.9s)
89
So here are our four steps.
9:32.53 – 9:34.35 (1.8s)
90
Well, it took us a number of years, And it took a number of iterations in order to be able to figure out which were the correct overlays that worked for students in learning this to make it easy.
9:34.97 – 9:47.13 (12.2s)
91
We took Perceive the Environment, where the brain is already in an observational mode, making an assessment of everything that's going on around it.
9:48.73 – 9:57.31 (8.6s)
92
We said, well, what if we harness that power and we augment it?
9:57.15 – 10:02.03 (4.9s)
93
So we taught students techniques for detailed analytic observation.
10:02.27 – 10:07.09 (4.8s)
94
Okay, that's just a fancy way of saying teaching their brains to extract more details from whatever it is they're observing.
10:07.25 – 10:13.85 (6.6s)
95
Now, it doesn't matter if they're observing a Shakespeare play, a nursing simulation, a business proposal, what is being observed is not the point.
10:13.83 – 10:22.23 (8.4s)
96
Conditioning the brain to use that step to extract more details from it is the point.
10:22.81 – 10:28.33 (5.5s)
97
We took the second step and we said if the brain is already in a mode of asking what's a danger and a reward, what's a threat and what's something to value, then why don't we take that step, harness it, and augment it?
10:28.67 – 10:40.65 (12.0s)
98
So we taught students techniques for complex question clarification.
10:41.09 – 10:45.59 (4.5s)
99
We took the next step to decide between danger and reward.
10:46.49 – 10:49.93 (3.4s)
100
We said, if the brain is already in a reasoning mode making determinations between different things, what if we harness that step and augment it and give students techniques for multivariant evaluation?
10:50.39 – 11:00.93 (10.5s)
101
Another fancy way of saying being able to weigh lots of different things against each other at the same time.
11:01.27 – 11:06.71 (5.4s)
102
And we took the final step to act on a decision.
11:06.71 – 11:09.75 (3.0s)
103
We said, well, if the brain is already in a mode of drawing conclusions, let's harness that capacity and augment it and give students the ability to form complex conclusions, the kinds of conclusions that do justice to the complex situations that we face in our lives.
11:09.75 – 11:25.27 (15.5s)
104
So we took all of these things and we distilled critical thinking down to just four acts, four primal acts, four acts that your brain does thousands of times a day.
11:25.27 – 11:36.29 (11.0s)
105
You know, have you ever thought about the fact that we teach students math and we teach them how to write and we teach them how to read, but we do not teach students how to think critically?
11:36.29 – 11:47.89 (11.6s)
106
That seems particularly odd, doesn't it?
11:47.89 – 11:51.11 (3.2s)
107
Well, let me explain to you why that might be.
11:51.11 – 11:53.85 (2.7s)
108
We know the foundation, the core act of teaching people to read.
11:53.37 – 12:00.73 (7.4s)
109
Well, there's There's sight recognition, there's vocabulary, potentially there's phonics, there's things like that.
12:00.73 – 12:05.51 (4.8s)
110
All the things that you learned when you learned to read.
12:05.47 – 12:08.21 (2.7s)
111
And you use all of those same foundations no matter what you read today as adults.
12:08.13 – 12:14.13 (6.0s)
112
Whether you read things as a doctor, whether you read poetry, whatever it is you read, you do so because you have mastered those core skills of reading.
12:14.03 – 12:22.95 (8.9s)
113
Well, we don't teach people to think critically because perhaps until now we had not identified the core skills of thinking.
12:22.95 – 12:33.77 (10.8s)
114
But what if those four steps that I described to you are in fact those four core steps of thinking?
12:34.49 – 12:42.09 (7.6s)
115
If we look at our list here, what we discovered was that when we taught students those four steps, all of these other things came along for the ride.
12:43.85 – 12:53.43 (9.6s)
116
Oh sure, if you're going to engage in innovation, there are certain additional things that we want your brain to do.
12:53.95 – 12:59.21 (5.3s)
117
But the simple fact of the matter is that you cannot engage in problem solving at all without making a detailed observation of the factors that might matter to the problem, formulating a correct and complex insightful question about that problem, weighing out different pieces of information as they may relate and impact your conclusion to that problem, and ultimately drawing a complex conclusion.
13:00.47 – 13:25.47 (25.0s)
118
Nor can you engage in strategizing, nor can you engage in innovating, nor can you do any other of the critical thinking acts that we mentioned, or any of the critical thinking acts that you might be thinking of right now.
13:27.13 – 13:39.77 (12.6s)
119
They all depend first and foremost on that primal skill of critical thinking that we taught students how to do better, something that anyone can learn.
13:40.47 – 13:50.39 (9.9s)
120
Well, how did it work out?
13:52.47 – 13:53.71 (1.2s)
121
We had first and second undergraduate students, undergraduates, who after just one course wrote papers that when we presented them to colleagues at other universities were typically rated as graduate-level work.
13:56.33 – 14:12.65 (16.3s)
122
Just a two-week intervention at a high school in Harlem, New York, not only saw wonderful increased gains in critical thinking, but something that we didn't even teach the students, increased complexity in their sentence structures.
14:14.13 – 14:27.65 (13.5s)
123
Class discussions became richer and more invigorated, with students often being the ones to take the lead, students who respected one another's ideas more, whether or not they disagreed, sometimes especially if they disagreed, because regardless of what we thought, we all know that we could respect one another's reasoning process, something that might be important in the world today.
14:28.39 – 14:54.49 (26.1s)
124
And it only worked in every discipline in which we tried it.
14:57.27 – 15:01.51 (4.2s)
125
as noted by faculty in those disciplines and faculty across the discipline, who said they'd never seen such complex critical thinking in their lives.
15:02.55 – 15:12.01 (9.5s)
126
But it also worked outside of class.
15:14.07 – 15:16.07 (2.0s)
127
I can't tell you the number of comments in person and in course evaluations that we received from students who talked about how this affected how they made decisions in their lives.
15:17.51 – 15:26.93 (9.4s)
128
And I got this one note slipped under my door at the end of a semester.
15:28.53 – 15:32.09 (3.6s)
129
which said, it helped me deal with my personal issues and my relationships because it gave me a new way to think through things like never before.
15:33.37 – 15:41.33 (8.0s)
130
This has changed how I think forever.
15:42.07 – 15:44.63 (2.6s)
131
This is one of the few classes I had that isn't just about school.
15:44.37 – 15:48.95 (4.6s)
132
What's better than that?
15:50.53 – 15:51.51 (1.0s)
133
So, we solved the sandbox problem Because we built critical thinking on a way that's natural, that leverages our natural, most basic, most instinctive brain function, and turned it into an intellectual set of skills, we made it something that everyone in the world can learn, regardless of their age, regardless of what you do, regardless of whether or not you get a fancy education.
15:54.79 – 16:22.69 (27.9s)
134
We found a way to teach critical thinking that was at once easy to learn, yet not only didn't undermine the complexity of critical thinking, it augmented it.
16:25.47 – 16:35.69 (10.2s)
135
Listen, researchers tell us this.
16:37.47 – 16:39.79 (2.3s)
136
The single biggest determinant for the decisions our kids make in their lives, high-stakes decisions, with respect to drug use, peer pressure, career choice, is not their raw intellect, it's not how smart they are, it's their critical thinking skills.
16:40.45 – 16:57.67 (17.2s)
137
And a recent survey of 1,000 employers said that the number one skill they are seeking, but do not find enough of, in employees is critical thinking.
16:58.73 – 17:08.29 (9.6s)
138
Well, we figured out how to teach critical thinking.
17:11.11 – 17:13.21 (2.1s)
139
We figured out how to teach everybody.
17:13.33 – 17:15.71 (2.4s)
140
We can teach it in elementary school classrooms, corporate boardrooms, and everywhere in between.
17:15.23 – 17:21.89 (6.7s)
141
And given the problems facing the world today, I think we could use a little more critical thinking.
17:22.47 – 17:27.91 (5.4s)
142
What do you think?
17:28.49 – 17:29.77 (1.3s)
143
Thank you.
17:30.31 – 17:31.13 (0.8s)

本视频练习技巧
为了有效提高您的英语流利度和发音练习，建议练习者将注意力集中在视频中的语速和语调上。可以从较慢的速度开始跟读，逐渐提高到正常语速，以适应不同的口语场景。在进行跟读时，特别要注意批判性思维相关术语的发音，确保您能够准确表达。这不仅能提升您的口语能力，从而在雅思口语测试中表现得更加自如，同时也能帮助您在探讨复杂话题时更加自信。在练习过程中，建议时不时停顿，进行自我反思，以加深对批判性思维概念的理解。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
如何在ShadowingEnglish上有效练习
- 选择您的视频： 挑选一段语音清晰、自然的YouTube视频。TED演讲，BBC新闻，电影片段，播客或雅思口语范例都很好。将URL粘贴到搜索栏中。从较短的视频（短于5分钟）以及您真正感兴趣的内容开始——兴趣是最重要的导师。
- 先听，理解上下文： 第一次听的时候，将速度保持在1倍速并仅仅倾听。还不要尝试重复。专注于理解其含义，收集新词汇，并注意讲话人如何强调单词，连读声音及使用停顿。
- 设置跟读模式：
- 等待模式：选择
+3s或+5s——在每句话播放完毕后，视频会自动暂停以便您有时间大声重复它。如果您想完全控制并在每次重复后由您自己点击下一步，请选择手动。 - 字幕同步：YouTube字幕有时会在音频前或后略微出现。使用
±100ms使它们完美对齐以助您准确跟读。
- 等待模式：选择
- 大声跟读（核心练习）： 这是真正发生改变的一步。当一个句子播放出来立刻——或在暂停期间——大声、清晰且自信地重复出来。千万不要只是张张嘴：要模仿说话者的准确节奏、重音、音高和连读。力求听上去就像说话者的影子，而不仅是逐字背诵。使用重复功能多次练习同一个句子，直到感觉自然为止。
- 提高难度： 当练习段落变得相对舒适后，就去挑战自我。将速度增加至 <code>1.25x</code> 或甚至 <code>1.5x</code> 以训练高速语言反射。或者将等待模式调整为 <code>关闭</code> 以进行连续跟读——这是最进阶同样收益最大的模式。持续的每日15–30分钟的练习将可以在几周内产生可见的效果。
