GUNTHER ROLAND:
One of the changes

2
00:00:06,830 --> 00:00:08,660
that we made over the
last three or four

3
00:00:08,660 --> 00:00:14,780
years was to flip the
classroom in 8.13 and 8.14.

4
00:00:14,780 --> 00:00:18,560
Essentially what we found is
that we spend a lot of time

5
00:00:18,560 --> 00:00:26,300
in class with lectures by the
lab staff which in the end

6
00:00:26,300 --> 00:00:29,910
seemed to be only moderately
useful in really getting

7
00:00:29,910 --> 00:00:32,070
the material across.

8
00:00:32,070 --> 00:00:34,960
So what we decided
to do was to export

9
00:00:34,960 --> 00:00:42,570
the lectures in the form of
videos to the MITx platform

10
00:00:42,570 --> 00:00:46,980
and replace the time that
we spent on that previously

11
00:00:46,980 --> 00:00:50,430
with in-class exercises
and class discussions

12
00:00:50,430 --> 00:00:55,230
to really rehearse some of the
concepts that were introduced

13
00:00:55,230 --> 00:00:58,020
in the lectures in class,
which also gives us

14
00:00:58,020 --> 00:01:00,720
a much closer communication
with the students.

15
00:01:00,720 --> 00:01:03,510
And you can find out what
it is that really needs

16
00:01:03,510 --> 00:01:06,420
to be explored in more depth.

17
00:01:06,420 --> 00:01:08,874
The other thing
that we did is move

18
00:01:08,874 --> 00:01:10,790
the prep questions for
each of the experiments

19
00:01:10,790 --> 00:01:12,930
also to that platform.

20
00:01:12,930 --> 00:01:15,570
What is important
there is that we

21
00:01:15,570 --> 00:01:18,150
can give the students
instantaneous feedback

22
00:01:18,150 --> 00:01:21,030
on whether they got the
question right or not,

23
00:01:21,030 --> 00:01:27,560
and remove the manuals for the
labs onto the same platform

24
00:01:27,560 --> 00:01:31,420
to have a lot of
that in one place.

25
00:01:31,420 --> 00:01:33,780
And I think, as I
said, the main benefit

26
00:01:33,780 --> 00:01:36,570
is really that we can use
the time that we free up

27
00:01:36,570 --> 00:01:39,540
in the class for
discussions and exercises

28
00:01:39,540 --> 00:01:41,790
that are much more effective
than the students sitting

29
00:01:41,790 --> 00:01:45,470
there and listening
to one of us talk.
