00:00:00,500 --> 00:00:03,330
NARRATOR: Representing an
entire university curriculum,

2
00:00:03,330 --> 00:00:05,870
MIT OpenCourseWare is
unique in the world

3
00:00:05,870 --> 00:00:08,690
of open educational resources.

4
00:00:08,690 --> 00:00:12,810
With so many courses online,
currently over 2,300,

5
00:00:12,810 --> 00:00:14,850
we're always working
on better ways

6
00:00:14,850 --> 00:00:19,990
to help you find courses and
make sense of the collection.

7
00:00:19,990 --> 00:00:22,710
This new, interactive
visualization tool,

8
00:00:22,710 --> 00:00:25,280
the MIT Undergraduate
Curriculum Map,

9
00:00:25,280 --> 00:00:28,150
is a great way to
explore what OCW's broad,

10
00:00:28,150 --> 00:00:32,049
curriculum coverage
really means.

11
00:00:32,049 --> 00:00:36,680
Each circle or node is
a subject taught at MIT.

12
00:00:36,680 --> 00:00:39,440
A node that's blue is on OCW.

13
00:00:39,440 --> 00:00:43,206
Grayed nodes are subjects
not currently on OCW.

14
00:00:43,206 --> 00:00:48,860
A line between two nodes shows
a prerequisite relationship.

15
00:00:48,860 --> 00:00:51,490
Rest your mouse on any
node and its number,

16
00:00:51,490 --> 00:00:53,385
title and prerequisites
are highlighted.

17
00:00:55,910 --> 00:00:57,790
Here in the Department
of Mathematics,

18
00:00:57,790 --> 00:01:00,920
you can see that most
subjects are on OCW.

19
00:01:00,920 --> 00:01:04,019
Click on any blue node
to see a link to the OCW

20
00:01:04,019 --> 00:01:05,980
version of the course.

21
00:01:05,980 --> 00:01:11,760
Here's 1801, Calculus 1.

22
00:01:11,760 --> 00:01:14,020
What else can you
learn from the map?

23
00:01:14,020 --> 00:01:16,870
Well, you can find important
foundational courses

24
00:01:16,870 --> 00:01:20,350
by looking for nodes that
are heavily connected.

25
00:01:20,350 --> 00:01:23,960
Here's 1806, Pre-algebra,
which is a prerequisite

26
00:01:23,960 --> 00:01:25,247
for many other subjects.

27
00:01:27,870 --> 00:01:30,480
You can also search for
courses by keywords found

28
00:01:30,480 --> 00:01:33,230
in the titles or topic tags.

29
00:01:33,230 --> 00:01:36,380
For instance, here are the
undergraduate courses currently

30
00:01:36,380 --> 00:01:38,890
offered on algorithms.

31
00:01:38,890 --> 00:01:43,960
You can show on the map or view
details on a specific class

32
00:01:43,960 --> 00:01:46,910
by clicking.

33
00:01:46,910 --> 00:01:50,140
Here are a few things to keep in
mind about the curriculum map.

34
00:01:50,140 --> 00:01:52,170
First, it only reflects
about one third

35
00:01:52,170 --> 00:01:57,440
of the total OCW publication,
its undergraduate courses only.

36
00:01:57,440 --> 00:02:01,120
It does not show any graduate
courses, nor any special topic

37
00:02:01,120 --> 00:02:05,510
seminars that are outside
the standard curriculum.

38
00:02:05,510 --> 00:02:07,590
Finally, the map
doesn't show subjects

39
00:02:07,590 --> 00:02:09,770
that are no longer
taught at MIT,

40
00:02:09,770 --> 00:02:12,360
but which are still shared
and quite popular on OCW.

41
00:02:15,040 --> 00:02:17,360
For the complete
OCW picture, you'll

42
00:02:17,360 --> 00:02:20,150
want to keep referring back
to our many other fine courses

43
00:02:20,150 --> 00:02:24,210
tools, along with
the curriculum map.

44
00:02:24,210 --> 00:02:26,830
We hope this curriculum map
helps you understand and make

45
00:02:26,830 --> 00:02:30,170
even better use of OCW's
extensive collection of MIT

46
00:02:30,170 --> 00:02:31,460
teaching materials.

47
00:02:31,460 --> 00:02:35,360
Always free and
always open for you.
