DAVID MALAN: Hello world,
my name is David Malan,

2
00:00:02,730 --> 00:00:06,030
and this is CS50's Introduction
to Programming with Scratch,

3
00:00:06,030 --> 00:00:08,880
a graphical programming
language from MIT's Media Lab

4
00:00:08,880 --> 00:00:11,752
via which you can program by
dragging and dropping puzzle pieces.

5
00:00:11,752 --> 00:00:14,460
Now, while you might be thinking
that Scratch is best for someone

6
00:00:14,460 --> 00:00:17,250
younger than you, I actually
didn't start using Scratch, myself,

7
00:00:17,250 --> 00:00:18,418
until graduate school.

8
00:00:18,418 --> 00:00:20,460
I was cross-registered,
at the time, for a course

9
00:00:20,460 --> 00:00:24,300
at MIT taught by Professor Mitchel
Resnick, whose team designed Scratch.

10
00:00:24,300 --> 00:00:27,930
And ever since, we've been using Scratch
in the first week of CS50 itself--

11
00:00:27,930 --> 00:00:31,230
Harvard University's introduction to
the intellectual enterprises of computer

12
00:00:31,230 --> 00:00:33,000
science and the arts of programming.

13
00:00:33,000 --> 00:00:35,400
A course that you can
take right after this one.

14
00:00:35,400 --> 00:00:38,280
Indeed, this course, taught
by CS50's own Brian Yu,

15
00:00:38,280 --> 00:00:42,300
prepares you all the more
for that first week of CS50.

16
00:00:42,300 --> 00:00:45,600
BRIAN YU: Hi, my name is Brian, and
I teach Introduction to Programming

17
00:00:45,600 --> 00:00:46,500
with Scratch.

18
00:00:46,500 --> 00:00:49,410
In this course, you'll learn how
to use Scratch to build stories,

19
00:00:49,410 --> 00:00:51,420
and animations, and games, and more.

20
00:00:51,420 --> 00:00:53,850
And along the way we'll
introduce you to programming.

21
00:00:53,850 --> 00:00:56,760
Exploring topics like functions,
which you can use to make something

22
00:00:56,760 --> 00:00:58,230
happen in your project.

23
00:00:58,230 --> 00:01:00,480
Events that your project can respond to.

24
00:01:00,480 --> 00:01:03,390
Loops that can make something in
your project happen multiple times.

25
00:01:03,390 --> 00:01:05,489
Or conditions that
can allow your project

26
00:01:05,489 --> 00:01:07,800
to make a decision about what to do.

27
00:01:07,800 --> 00:01:11,190
During the course, I'll show you how you
can use these tools and ideas to build

28
00:01:11,190 --> 00:01:12,510
some interesting projects.

29
00:01:12,510 --> 00:01:15,660
And we'll also give you the
opportunity to design and create

30
00:01:15,660 --> 00:01:17,550
projects that are exciting to you.

31
00:01:17,550 --> 00:01:22,530
This is an Introduction to Programming
with Scratch, and this is CS50.

32
00:01:22,530 --> 00:01:24,000
