It was a Saturday afternoon in May,
1
15911
3179
嗰日係五月一個星期六嘅下晝
00:19
and I suddenly realized
2
19090
2514
我突然意識到聽日就係母親節
00:21
that the next day was Mother's Day,
3
21604
3454
00:25
and I hadn't gotten anything for my mom,
4
25058
1846
而我仲未準備禮物俾我媽咪
00:26
so I started thinking about
5
26904
1401
所以我開始諗
00:28
what should I get my mom for Mother's Day?
6
28305
2337
我要送佢乜嘢做母親節禮物呢?
00:30
I thought, why don't I make her
7
30642
1844
我諗點解唔利用我同我嘅研究小組
00:32
an interactive Mother's Day card
8
32486
3049
喺麻省理工媒體實驗室開發嘅軟件 Scratch
00:35
using the Scratch software that I'd been developing
9
35535
2708
00:38
with my research group at the MIT Media Lab?
10
38243
3817
嚟做張有互動嘅母親節卡俾佢呢?
00:42
We developed it so that people could easily create
11
42060
3380
我哋整咗呢個軟件
令人可以輕鬆創作佢哋自己
00:45
their own interactive stories and games and animations,
12
45440
4244
有互動功能嘅故事、遊戲或者動畫
00:49
and then share their creations with one another.
13
49684
3769
而且同人分享佢哋嘅創作
00:53
So I thought, this would be an opportunity to use Scratch
14
53453
3868
於是我諗或者呢個係一個好機會
利用 Scratch 去整一張互動嘅卡俾我媽咪
00:57
to make an interactive card for my mom.
15
57321
2900
01:00
Before making my own Mother's Day card,
16
60221
2176
喺我做母親節卡之前
01:02
I thought I would take a look
17
62397
1985
我諗我可以先睇睇 Scratch 個網站
01:04
at the Scratch website.
18
64382
1573
01:05
So over the last several years, kids around the world
19
65955
3358
過去幾年,世界各地八歲以上嘅小朋友
01:09
ages 8 and up, have shared their projects,
20
69313
3194
分享咗佢哋嘅作品
01:12
and I thought, I wonder if, of those three million projects,
21
72507
3435
所以我諗喺呢三百萬件作品裏邊
01:15
whether anyone else has thought to put up Mother's Day cards.
22
75942
3385
會唔會有人上載咗母親節卡呢
01:19
So in the search box I typed in
23
79327
2994
所以我就喺搜尋嗰度打「母親節」
01:22
"Mother's Day,"
24
82321
1545
01:23
and I was surprised and delighted to see a list
25
83866
3003
我又驚訝又開心睇到
01:26
of dozens and dozens of Mother's Day cards
26
86869
2704
成頁有好多好多嘅母親節卡
01:29
that showed up on the Scratch website,
27
89573
2514
好多卡都係由一啲 好似我噉鍾意拖著做嘅人
01:32
many of them just in the past 24 hours
28
92087
2318
01:34
by procrastinators just like myself.
29
94405
3206
喺 24 小時之內上載嘅
01:37
So I started taking a look at them. (Music)
30
97611
3122
當我開始睇呢啲作品
(音樂)
01:40
I saw one of them that featured a kitten
31
100733
2456
我睇到一張特寫小貓 同小貓媽咪一齊嘅卡片
01:43
and her mom and wishing her mom a happy Mother's Day.
32
103189
6871
卡中嘅小貓祝媽咪母親節快樂
作者仲非常貼心噉
01:50
And the creator very considerately
33
110060
2531
01:52
offered a replay for her mom.
34
112591
3504
為佢自己母親整咗一個重播按鈕
01:56
Another one was an interactive project where,
35
116095
2384
另一個係互動作品
01:58
when you moved the mouse over the letters of "Happy Mom Day,"
36
118479
3198
當你將滑鼠移到 「母親節快樂」嘅字上面時
02:01
it reveals a special happy Mother's Day slogan.
37
121677
4920
會出現一句特別嘅母親節嘅祝福句子
02:06
(Music) In this one, the creator told a narrative
38
126597
3983
(音樂)
而喺呢件作品
創作者講述佢自己 點樣用谷歌搵出母親節係幾時
02:10
about how she had Googled to find out
39
130580
2659
02:13
when Mother's Day was happening.
40
133239
3117
02:16
(Typing) And then once she found out when Mother's Day was happening,
41
136356
4143
(打字聲)
而當佢知道母親節係幾時嗰陣
02:20
she delivered a special Mother's Day greeting
42
140499
2478
佢立即送出特別嘅母親節祝福
02:22
of how much she loved her mom.
43
142977
3627
去表達佢有幾愛佢媽媽
02:26
So I really enjoyed looking at these projects
44
146604
2225
我真係好鍾意 睇呢啲作品、同呢啲作品互動
02:28
and interacting with these projects.
45
148829
1652
02:30
In fact, I liked it so much that, instead of making my own project,
46
150481
3841
事實上,由於我太鍾意呢啲作品
原本諗著親手整張
02:34
I sent my mom links to about a dozen of these projects. (Laughter)
47
154322
4754
但後來就直接將十幾個作品嘅連結
發送俾我媽咪
(笑聲)
02:39
And actually, she reacted exactly the way that I hoped that she would.
48
159076
3580
而其實,佢嘅反應就係我想要嘅
02:42
She wrote back to me and she said,
49
162656
1385
佢回覆我話
02:44
"I'm so proud to have a son that created the software
50
164041
3267
「我非常為我嘅仔仔感到驕傲
佢能夠整到噉嘅軟件
02:47
that allowed these kids to make Mother's Day cards for their mothers."
51
167308
4112
令小朋友可以整母親節卡
送俾佢哋嘅媽媽。」
02:51
So my mom was happy, and that made me happy,
52
171420
3800
所以見到我媽咪好高興,我都好開心
02:55
but actually I was even happier for another reason.
53
175220
4624
但事實上我仲有一個更開心嘅原因
02:59
I was happy because these kids were using Scratch
54
179844
3959
我開心係因為呢啲小朋友能夠按照
03:03
just in the way that we had hoped that they would.
55
183803
2801
我哋希望見到嘅用法去用 Scratch
03:06
As they created their interactive Mother's Day cards,
56
186604
2811
當佢哋製作互動母親節卡嘅時候
03:09
you could see that they were really
57
189415
2281
你可以睇到佢哋真係 愈嚟愈對新科技純熟
03:11
becoming fluent with new technologies.
58
191696
3312
03:15
What do I mean by fluent?
59
195008
1463
噉純熟係咩呢?
03:16
I mean that they were able to start expressing themselves
60
196471
4032
我係指佢哋可以開始表達佢哋自己
03:20
and to start expressing their ideas.
61
200503
2777
開始表達佢哋嘅諗法
03:23
When you become fluent with language,
62
203280
2654
當你開始對一種語言純熟嘅時候
03:25
it means you can write an entry in your journal
63
205934
3537
意味著你可以喺你嘅日記上面寫嘢
03:29
or tell a joke to someone or write a letter to a friend.
64
209471
4053
或者話講笑話俾人哋聴
或者寫封信俾朋友
03:33
And it's similar with new technologies.
65
213524
3157
新科技都係同樣道理
03:36
By writing, be creating these interactive Mother's Day cards,
66
216681
4182
透過書寫或者創作呢啲互動嘅母親節卡
03:40
these kids were showing that they were really fluent
67
220863
2530
呢啲小朋友會俾人睇到
佢哋對呢啲新科技有幾純熟
03:43
with new technologies.
68
223393
1673
03:45
Now maybe you won't be so surprised by this,
69
225066
2765
你或者對呢樣嘢唔覺得驚訝
03:47
because a lot of times people feel that
70
227831
2696
因為好多時人都會覺得
03:50
young people today can do all sorts of things with technology.
71
230527
3400
現今年輕人可以用科技做各式各樣嘅嘢
03:53
I mean, all of us have heard young people referred to as "digital natives."
72
233927
4461
我嘅意思係
我哋都聽過年輕人被稱為「數碼原生代」
03:58
But actually I'm sort of skeptical about this term.
73
238388
3797
某種程度上 我認為呢個用詞係有點問題嘅
04:02
I'm not so sure we should be thinking of young people as digital natives.
74
242185
3501
但我就唔太肯定
我哋應唔應該將年輕人視作數碼原生代
04:05
When you really look at it, how is it that young people
75
245686
2553
當你真係去睇呢樣嘢
年輕人花大部分時間喺新科技嗰度
04:08
spend most of their time using new technologies?
76
248239
3536
究竟係點嘅一回事呢?
04:11
You often see them in situations like this,
77
251775
3523
你經常見到嘅情況會係噉樣
04:15
or like this,
78
255298
2194
或者噉樣
04:17
and there's no doubt that young people
79
257492
1518
可以肯定嘅係年輕人對於上網 上網聊天、發短訊同打機
04:19
are very comfortable and familiar browsing
80
259010
3316
04:22
and chatting and texting and gaming.
81
262326
4522
都好自在、好熟
04:26
But that doesn't really make you fluent.
82
266848
3199
但呢啲並唔會真係令你純熟
04:30
So young people today have lots of experience
83
270047
3959
今日嘅年輕人對於新科技嘅互動
04:34
and lots of familiarity with interacting with new technologies,
84
274006
3795
好有經驗同埋好熟識
04:37
but a lot less so of creating with new technologies
85
277801
3405
但對於利用新科技去創作同表達嘅人 就少得多
04:41
and expressing themselves with new technologies.
86
281206
2972
04:44
It's almost as if they can read
87
284178
2392
即係話佢哋識得用新科技去睇嘢
04:46
but not write with new technologies.
88
286570
3333
但唔識得用新科技去寫嘢一樣
04:49
And I'm really interested in seeing, how can we help young people become fluent
89
289903
3898
而我就真係好想知道
點樣能夠令年輕人對科技更純熟
04:53
so they can write with new technologies?
90
293801
2529
令佢哋能夠用新科技去創作
04:56
And that really means that they need to be able to
91
296330
3360
即係話佢哋能夠 寫自己嘅電腦程式,或者寫編碼
04:59
write their own computer programs, or code.
92
299690
4512
05:04
So, increasingly, people are starting to recognize
93
304202
2712
於是,有趣地,人就開始認清
05:06
the importance of learning to code.
94
306914
3304
學習寫編碼嘅重要性
05:10
You know, in recent years, there have been
95
310218
2602
你知道近幾年有幾百個新機構同新網站
05:12
hundreds of new organizations and websites
96
312820
2892
05:15
that are helping young people learn to code.
97
315712
3294
幫助年輕人學習編寫編碼
05:19
You look online, you'll see places like Codecademy
98
319006
3591
你見到網上有類似 Codeacademy 噉樣嘅地方
05:22
and events like CoderDojo
99
322597
2371
有類似 CoderDojo 一樣嘅活動
05:24
and sites like Girls Who Code,
100
324968
2431
又有似 Girls Who Code
05:27
or Black Girls Code.
101
327399
1694
或者 Black Girls Code 呢一類嘅網站
05:29
It seems that everybody is getting into the act.
102
329093
3108
每一個人似乎都開始參與其中
05:32
You know, just at the beginning of this year,
103
332201
2583
你知道嗎,就喺年初
05:34
at the turn of the new year,
104
334784
1365
踏入新一年嗰陣
05:36
New York City Mayor Michael Bloomberg
105
336149
2660
紐約市長彭博為佢自己定下咗新年目標
05:38
made a New Year's resolution that he was going to learn
106
338809
2260
就係要喺 2012 年學識寫編碼
05:41
to code in 2012.
107
341069
2779
05:43
A few months later, the country of Estonia decided that
108
343848
3168
幾個月後,愛沙尼亞政府決定
05:47
all of its first graders should learn to code.
109
347016
3656
全國一年級學生都要學寫編碼
05:50
And that triggered a debate in the U.K.
110
350672
2792
呢樣嘢喺英國激發咗一場辯論
05:53
about whether all the children there should learn to code.
111
353464
4309
係咪要俾全部小朋友學寫編碼
05:57
Now, for some of you, when you hear about this,
112
357773
2843
宜家,你哋部分人,聽到呢個提議時
06:00
it might seem sort of strange about everybody learning to code.
113
360616
3608
或者會覺得有啲奇怪
做乜每個人都要學寫編碼
06:04
When many people think of coding, they think of it
114
364224
3150
當大部分人聽到編碼,佢哋會諗起
06:07
as something that only a very narrow sub-community
115
367374
3576
只有少數人會做嘅嘢
06:10
of people are going to be doing,
116
370950
2658
06:13
and they think of coding looking like this.
117
373608
2922
呢個就係佢哋對編碼嘅印象
06:16
And in fact, if this is what coding is like,
118
376530
2166
事實上,假如程式真係噉嘅樣
06:18
it will only be a narrow sub-community of people
119
378696
2495
只會有好少人
06:21
with special mathematical skills and technological background
120
381191
3072
就係嗰啲 有特別嘅數學技能同科技背景嘅人
06:24
that can code.
121
384263
2266
至會寫編碼
06:26
But coding doesn't have to be like this.
122
386529
2500
但寫編碼唔需要噉樣
06:29
Let me show you about what it's like to code in Scratch.
123
389029
3979
就等我俾你睇下Scratch 裏邊嘅編碼 係點樣啦
06:33
So in Scratch, to code, you just snap blocks together.
124
393008
4279
喺 Scratch 裏面寫編碼 就好似砌積木噉
06:37
In this case, you take a move block,
125
397287
1915
喺呢個情況下
你移動一舊積木
06:39
snap it into a stack,
126
399202
1769
將佢同其他積木堆埋一齊
06:40
and the stacks of blocks control the behaviors
127
400971
2758
嗰堆積木就會控制 你嘅遊戲或者故事裏邊唔同角色嘅行為
06:43
of the different characters in your game or your story,
128
403729
3518
06:47
in this case controlling the big fish.
129
407247
2301
呢個例子裏面就係要控制一條大魚
06:49
After you've created your program, you can click on "share,"
130
409548
3451
當你整咗個程式之後
你可以點選「分享」
06:52
and then share your project with other people,
131
412999
3076
然後你就可以將你個程式同其他人分享
06:56
so that they can use the project
132
416075
1823
人哋就可以用到你嘅程式
06:57
and start working on the project as well.
133
417898
2974
而且可以對個程式做修改
07:00
So, of course, making a fish game isn't the only thing
134
420872
3322
當然,整一個同魚有關嘅遊戲並唔係
07:04
you can do with Scratch.
135
424194
1645
Scratch 唯一可以做嘅嘢
07:05
Of the millions of projects on the Scratch website,
136
425839
1980
喺 Scratch 網站度幾百萬嘅項目裏面
07:07
there's everything from animated stories
137
427819
2824
由動畫故事
07:10
to school science projects
138
430643
2416
到學校科學專題研究
07:13
to anime soap operas
139
433059
2064
動漫劇集
07:15
to virtual construction kits
140
435123
2322
虛擬建築工具箱
07:17
to recreations of classic video games
141
437445
2713
經典電玩遊戲嘅重新製作
07:20
to political opinion polls
142
440158
2269
民意調查
07:22
to trigonometry tutorials
143
442427
2640
三角幾何學教學
07:25
to interactive artwork, and, yes,
144
445067
2920
互動藝術作品都應有盡有
07:27
interactive Mother's Day cards.
145
447987
2784
當然仲有互動嘅母親節賀卡
07:30
So I think there's so many different ways
146
450771
3036
所以我認為啲人可以透過呢個軟件
07:33
that people can express themselves using this,
147
453807
3460
用好多唔用嘅方式表達自己嘅心意
07:37
to be able to take their ideas and share their ideas with the world.
148
457267
3400
仲有記低同埋分享俾全世界知 佢哋嘅諗法
07:40
And it doesn't just stay on the screen.
149
460667
2562
而且,佢唔止剩係喺電腦螢幕裏面
07:43
You can also code to interact with the physical world around you.
150
463229
3767
你可以寫一啲 可以同你周圍現實世界互動嘅編碼
07:46
Here's an example from Hong Kong,
151
466996
2479
呢裏有一個嚟自香港嘅例子
07:49
where some kids made a game
152
469475
1407
呢啲小朋友做咗一個遊戲
07:50
and then built their own physical interface device
153
470882
3281
佢哋整咗一個實體介面裝置
07:54
and had a light sensor, so the light sensor
154

個裝置有一個光感應器
呢個感應器會感應塊板上面嘅窿
07:57
detects the hole in the board,
155
477055
1943
07:58
so as they move the physical saw,
156
478998
2200
當佢哋郁把鋸時
08:01
the light sensor detects the hole
157
481198
2240
個感應器可以探測到個窿
08:03
and controls the virtual saw on the screen
158
483438
2956
從而控制螢幕上嘅一把虛擬嘅鋸去鋸樹
08:06
and saws down the tree.
159
486394
2780
08:09
We're going to continue to look at new ways
160
489174
2109
至於我哋,我哋會繼續搵新嘅方式
08:11
of bringing together the physical world and the virtual world
161
491283
3056
將現實世界同虛擬世界帶到黎
08:14
and connecting to the world around us.
162
494339
2928
去連接我哋嘅世界
08:17
This is an example from a new version of Scratch
163
497267
2233
呢個係 Scratch 嘅新版本
08:19
that we'll be releasing in the next few months,
164
499500
3623
將會喺幾個月之內發佈
08:23
and we're looking again to be able
165
503123
2050
我哋希望再次帶俾你新方向
08:25
to push you in new directions.
166
505173
1696
08:26
Here's an example.
167
506869
2264
舉個例
08:29
It uses the webcam.
168
509133
4074
有個程式需要用到網絡攝影機
08:33
And as I move my hand, I can pop the balloons
169
513207
4856
當我移動我隻手
我可以戳穿氣球或者郁一條蟲
08:38
or I can move the bug.
170
518063
2885
08:40
So it's a little bit like Microsoft Kinect,
171
520948
2565
呢樣有啲似微軟嘅 Kinect 裝置
08:43
where you interact with gestures in the world.
172
523513
2716
你可以用唔同姿勢同裏面嘅世界互動
08:46
But instead of just playing someone else's game,
173
526229
2244
但除咗玩其他人嘅遊戲
08:48
you get to create the games,
174
528473
2242
你可以自己寫遊戲
08:50
and if you see someone else's game,
175
530715
1383
如果你見到人哋嘅遊戲
08:52
you can just say "see inside,"
176
532098
2640
你只需要講「查看裏邊」
08:54
and you can look at the stacks of blocks that control it.
177
534738
2894
你就可以睇到嗰堆控制遊戲嘅積木
08:57
So there's a new block that says how much video motion there is,
178
537632
3555
呢舊新積木顯示影像動作嘅幅度
09:01
and then, if there's so much video motion,
179
541187
3121
如果有大動作
09:04
it will then tell the balloon to pop.
180
544308
3379
佢就會指示個氣球爆開
09:07
The same way that this uses the camera
181
547687
2384
呢樣嘢用同一方式
利用相機收集資料輸入到 Scratch
09:10
to get information into Scratch,
182
550071
2505
09:12
you can also use the microphone.
183
552576
3007
你亦可以用咪
09:15
Here's an example of a project using the microphone.
184
555583
3984
呢個係一個利用咪創作嘅例子
09:19
So I'm going to let all of you control this game
185
559567
2400
你哋都可以用你哋嘅聲音控制呢個遊戲
09:21
using your voices.
186
561967
2246
09:24
(Crickets chirping) (Shouts) (Chomping)
187
564213
16456
(蟋蟀叫聲) (大嗌) (咀嚼聲)
09:40
(Laughter)
188
580669
8629
(笑聲) (呼叫) (蝙蝠跌落聲)
(掌聲)
09:49
(Applause)
189
589298
8784
09:58
As kids are creating projects like this,
190
598082
2605
當小朋友哋喺度創作呢啲項目嘅時候
10:00
they're learning to code,
191
600687
2265
佢哋係學梗寫編碼
10:02
but even more importantly, they're coding to learn.
192
602952
3934
但更重要嘅係
佢哋係從寫編碼中學習
10:06
Because as they learn to code,
193
606886
2289
因為喺學習寫編碼嘅過程中
10:09
it enables them to learn many other things,
194
609175
3320
佢哋學到其他好多嘢
10:12
opens up many new opportunities for learning.
195
612495
2872
得到好多學習嘅新機會
10:15
Again, it's useful to make an analogy to reading and writing.
196
615367
4384
同樣地
閱讀同寫作嘅比喻喺呢度可以用到
10:19
When you learn to read and write, it opens up
197
619751
2940
當你學習閱讀同寫作嘅時候
10:22
opportunities for you to learn so many other things.
198
622691
3060
佢提供你學習其他更多事物嘅機會
10:25
When you learn to read, you can then read to learn.
199
625751
3760
當你學習閱讀嘅時候
你同時係透過閱讀去學習
10:29
And it's the same thing with coding.
200
629511
2188
寫編碼都係一樣
10:31
If you learn to code, you can code to learn.
201
631699
2547
當你學寫編碼嘅時候
你會學到其他嘢
10:34
Now some of the things you can learn are sort of obvious.
202
634246
2554
有啲你可以學嘅嘢係睇得到嘅
10:36
You learn more about how computers work.
203
636800
2498
譬如你會知道電腦點樣運作
10:39
But that's just where it starts.
204
639298
2318
但呢樣只係第一樣
10:41
When you learn to code, it opens up for you to learn
205
641616
2595
當你學寫編碼
佢為你打開學習其他好多嘢嘅大門
10:44
many other things.
206
644211
2245
10:46
Let me show you an example.
207
646456
2346
等我舉個例
10:48
Here's another project,
208
648802
2270
呢度有另一個項目
我第一次見到佢
10:51
and I saw this when I was visiting
209
651072
2268
係當我參觀一間電腦俱樂部嘅時候
10:53
one of the computer clubhouses.
210
653340
2142
10:55
These are after-school learning centers that we helped start
211
655482
3020
呢啲係我哋協助成立嘅課後學習中心
10:58
that help young people from low-income communities
212
658502
2762
幫助嚟自低收入社群嘅青年
11:01
learn to express themselves creatively with new technologies.
213
661264
4079
學習點樣利用新科技創意噉表達自己
11:05
And when I went to one of the clubhouses a couple years ago,
214
665343
2795
幾年前當我去其中一個俱樂部時
11:08
I saw a 13-year-old boy who was using our Scratch software
215
668138
3725
我見到一個十三歲嘅男仔
用梗我哋嘅 Scratch 軟件
11:11
to create a game somewhat like this one,
216
671863
2896
去寫一個類似呢個嘅遊戲
11:14
and he was very happy with his game and proud of his game,
217
674759
2923
對於自己嘅遊戲
佢非常開心同自豪
11:17
but also he wanted to do more.
218
677682
2965
但佢想做更加多
11:20
He wanted to keep score.
219
680647
2304
佢想個遊戲可以計到分
11:22
So this was a game where the big fish eats the little fish,
220
682951
3076
佢個遊戲係玩大魚食細魚
11:26
but he wanted to keep score, so that each time
221
686027
2927
佢希望可以做到計分
11:28
the big fish eats the little fish,
222
688954
3378
令每一次大魚食小魚嘅時候
11:32
the score would go up and it would keep track,
223
692332
2539
分數會增加同埋記低落嚟
11:34
and he didn't know how to do that.
224
694871
2512
但佢唔識得整
11:37
So I showed him.
225
697383
2265
所以我就話俾佢知點整
11:39
In Scratch, you can create something called a variable.
226
699648
3577
喺 Scratch 裏面
你可以建立一樣嘢叫「變量」
11:43
I'll call it score.
227
703225
4127
我會叫佢做「分數」
11:47
And that creates some new blocks for you,
228
707352
2831
跟著個軟件會幫你建立幾個新積木
11:50
and also creates a little scoreboard that keeps track of the score,
229
710183
4666
並且會建立一個細嘅計分板
記錄分數
11:54
so each time I click on "change score," it increments the score.
230
714849
5252
當我每次點擊「更新分數」嘅時候
分數就會增加
12:00
So I showed this to the clubhouse member --
231
720101
2525
於是我話咗呢樣嘢俾呢名俱樂部會員知
12:02
let's call him Victor -- and Victor,
232
722626
2701
就叫佢做域他
當域他見到 呢個積木可以幫佢增加分數時
12:05
when he saw that this block would let him increment the score,
233
725327
2802
12:08
he knew exactly what to do.
234
728129
1816
佢即刻知道點做
12:09
He took the block
235
729945
2314
佢將個積木擺喺佢嘅程式入面
12:12
and he put it into the program
236
732259
3044
12:15
exactly where the big fish eats the little fish.
237
735303
4193
就擺喺大魚食小魚嗰部分
12:19
So then, each time the big fish eats the little fish,
238
739496
5023
於是,每次當大魚食小魚
12:24
he will increment the score, and the score will go up by one.
239
744519
5995
佢都可以令到個分數增加
每次增加一分
12:30
And it's in fact working.
240
750514
1697
個計分仲係正常運作
12:32
And he saw this, and he was so excited,
241
752211
2254
佢見到噉樣,佢非常之興奮
12:34
he reached his hand out to me,
242
754465
1679
佢伸隻手過嚟
12:36
and he said, "Thank you, thank you, thank you."
243
756144
2549
同我講: 「唔該,唔該,唔該」
12:38
And what went through my mind was,
244
758693
2069
呢個時候我諗
12:40
how often is it that teachers are thanked by their students
245
760762
3042
學校裡面嘅老師有幾多時會
因為教咗學生「變量」呢樣嘢 而有學生唔該佢哋呢?
12:43
for teaching them variables? (Laughter)
246
763804
3403
(笑聲)
12:47
It doesn't happen in most classrooms,
247
767207
2481
呢樣好少喺喺課室發生
12:49
but that's because in most classrooms, when kids learn about variables,
248
769688
2959
噉係因為喺大部分嘅課室
當小朋友學習變量嗰陣
12:52
they don't know why they're learning it.
249
772647
2508
佢哋唔知道佢哋學呢樣嘢嘅原因
12:55
It's nothing that, really, they can make use of.
250
775155
2871
佢哋冇應用嘅機會
12:58
When you learn ideas like this in Scratch,
251
778026
2162
當你喺 Scratch 學習類似概念時
13:00
you can learn it in a way that's really meaningful and motivating for you,
252
780188
4103
你可以透過一種 有意義、可以推動到你嘅方式學習
13:04
that you can understand the reason for learning variables,
253
784291
2990
令你明白學習變量嘅原因
13:07
and we see that kids learn it more deeply
254
787281
2042
我哋見到小朋友更深入 更好地學習呢樣嘢
13:09
and learn it better.
255
789323
1415
13:10
Victor had, I'm sure, been taught about variables in schools,
256
790738
3041
我肯定域他佢喺學校有學過變量
13:13
but he really didn't -- he wasn't paying attention.
257
793779
2188
只係因為佢冇上堂冇留心啫
13:15
Now he had a reason for learning variables.
258
795967
2283
宜家,佢終於有一個學習變量嘅原因
13:18
So when you learn through coding, and coding to learn,
259
798250
3074
所以當你學編碼 並透過編碼去學習
13:21
you're learning it in a meaningful context, and that's the best way of learning things.
260
801324
4884
你就係有意義噉去學習
而呢個就係最好嘅學習方法
13:26
So as kids like Victor are creating projects like this,
261
806208
3455
所以當好似域他噉嘅小朋友 整梗佢哋嘅項目嗰陣
13:29
they're learning important concepts like variables,
262
809663
2784
佢哋係學梗好似變量呢啲重要嘅概念
13:32
but that's just the start.
263
812447
2128
但呢個只係第一樣嘢
13:34
As Victor worked on this project and created the scripts,
264
814575
3850
當域他做梗呢個項目
寫梗啲程式碼嘅時候
13:38
he was also learning about the process of design,
265
818425
3252
佢係學梗設計嘅過程
13:41
how to start with the glimmer of an idea
266
821677
2619
點樣將一個諗法
13:44
and turn it into a fully-fledged, functioning project
267
824296
2906
變成一個完整、可以運作嘅軟件
13:47
like you see here.
268
827202
2507
就好似你睇到佢噉
13:49
So he was learning many different core principles of design,
269
829709
4040
所以佢喺度學梗好多 唔同嘅、核心嘅設計原理
13:53
about how to experiment with new ideas,
270
833749
3242
學點樣測試新諗法
13:56
how to take complex ideas and break them down into simpler parts,
271
836991
4705
學點樣將複雜諗法拆做細小嘅嘢
14:01
how to collaborate with other people on your projects,
272
841696
2990
點樣同其他人做項目
14:04
about how to find and fix bugs when things go wrong,
273
844686
3451
點樣喺出錯嗰陣,搵出同糾正錯誤
14:08
how to keep persistent and to persevere
274
848137
3054
就算當事情唔係咁如意 面對挫折嘅時候
14:11
in the face of frustrations when things aren't working well.
275
851191
3405
點樣堅持不懈
14:14
Now those are important skills
276
854596
1773
呢啲都係重要嘅技能
14:16
that aren't just relevant for coding.
277
856369
2868
唔係剩係同編碼有關
14:19
They're relevant for all sorts of different activities.
278
859237
2827
佢哋都同所有唔同嘅活動有關
14:22
Now, who knows if Victor is going to grow up and become
279
862064
3168
冇人知道域他長大之會唔會
成為一個程式員
14:25
a programmer or a professional computer scientist?
280
865232
2924
或者專業計算機科學家?
14:28
It's probably not so likely,
281
868156
1812
可能唔太可能啦
14:29
but regardless of what he does,
282
869968
1788
唔理佢將來會做乜
14:31
he'll be able to make use of these design skills that he learned.
283
871756
3704
佢呢啲學返嚟嘅設計技能 仍然都會用得著
14:35
Regardless of whether he grows up to be a marketing manager
284
875460
2584
不管佢將來係唔係 會成為一個市場推廣經理
14:38
or a mechanic or a community organizer,
285
878044
3120
工程師,或者社區組織者
14:41
that these ideas are useful for everybody.
286
881164
2456
呢啲概念對於每一個人嚟講都好有用
14:43
Again, it's useful to think about this analogy with language.
287
883620
3922
再一次
用語言呢個比喻去諗呢件事係有用嘅
14:47
When you become fluent with reading and writing,
288
887542
4356
當你可以流暢噉閱讀同寫作時
14:51
it's not something that you're doing
289
891898
2441
唔代表你會做一個專業嘅作家
14:54
just to become a professional writer.
290
894339
1960
14:56
Very few people become professional writers.
291
896299
2697
好少人會成為專業作家
14:58
But it's useful for everybody to learn how to read and write.
292
898996
3568
但對所有人嚟講
學習閱讀同寫作係有用嘅
15:02
Again, the same thing with coding.
293
902564
2095
呢個同寫編碼係同一道理
15:04
Most people won't grow up to become professional
294
904659
2222
大部分人喺長大之後唔會成為
15:06
computer scientists or programmers,
295
906881
3219
專業計算機科學家或者程式員
15:10
but those skills of thinking creatively,
296
910100
2338
但創意思維、有系統嘅推論、同人合作
15:12
reasoning systematically, working collaboratively --
297
912438
2514
15:14
skills you develop when you code in Scratch --
298
914952
2710
呢啲喺 Scratch 寫編碼嗰陣 發展出嚟嘅技能
15:17
are things that people can use no matter what they're doing in their work lives.
299
917662
4822
喺任何職業都可以用到
15:22
And it's not just about your work life.
300
922484
2376
唔剩止你份工
15:24
Coding can also enable you to
301
924860
2720
寫編碼可以
令你喺平日生活裏邊
15:27
express your ideas and feelings in your personal life.
302
927580
3176
表達你嘅諗法同情感
15:30
Let me end with just one more example.
303
930756
2673
就俾我再講多一個例子嚟到結束
15:33
So this is an example that came from
304
933429
3127
呢個例子係關於
15:36
after I had sent the Mother's Day cards to my mom,
305
936556
4468
我將母親節卡發比媽咪之後
15:41
she decided that she wanted to learn Scratch.
306
941024
3101
佢決定要學習用 Scratch

So she made this project for my birthday
307
944125
3031
於是佢喺我嘅生日嗰時整咗呢個項目
15:47
and sent me a happy birthday Scratch card.
308
947156
3576
發咗張 Scratch 生日卡俾我
15:50
Now this project is not going to win any prizes for design,
309
950732

雖然宜家呢個作品唔會贏到設計獎
15:54
and you can rest assured that my 83-year-old mom
310
954588
2975
而且你可以坐係度好肯定
我 83 歲嘅媽媽
15:57
is not training to become a professional programmer or computer scientist.
311
957563
4237
唔係為咗受訓成為專業程式員
或者計算機科學家
16:01
But working on this project enabled her
312
961800
2972
但做呢個項目令到佢
16:04
to make a connection to someone that she cares about
313
964772
2666
可以連繫著佢關心嘅人
16:07
and enabled her to keep on learning new things
314
967438
2808
同埋令佢繼續學習新嘢
16:10
and continuing to practice her creativity
315
970246
2432
令佢繼續用佢嘅創意
16:12
and developing new ways of expressing herself.
316
972678
3175
令佢發展新嘅方式去表達自己
16:15
So as we take a look and we see that
317
975853
4211
所以,當我哋留意
我哋可以見到
