PATRICK JOHNSON: My
name is Patrick Johnson.

4
00:00:06,840 --> 00:00:08,840
I'm an assistant
teaching professor

5
00:00:08,840 --> 00:00:11,060
in the Department of
Physics at Georgetown.

6
00:00:11,060 --> 00:00:13,490
During class with
large lectures,

7
00:00:13,490 --> 00:00:16,670
it's hard to get students to
respond to any questions, even

8
00:00:16,670 --> 00:00:18,180
the most simple of questions.

9
00:00:18,180 --> 00:00:20,480
And so I used Poll
Everywhere, which

10
00:00:20,480 --> 00:00:22,790
is a system that
allows me to get

11
00:00:22,790 --> 00:00:25,760
mass feedback from my
students anonymously in class.

12
00:00:25,760 --> 00:00:27,860
I used it for
Physics 101 and 102,

13
00:00:27,860 --> 00:00:30,830
and I really enjoyed using it.

14
00:00:30,830 --> 00:00:34,400
Having a way for students to
provide anonymous feedback

15
00:00:34,400 --> 00:00:38,660
allows me to ask questions and
get large numbers of students

16
00:00:38,660 --> 00:00:39,500
to respond.

17
00:00:39,500 --> 00:00:42,150
They can answer what
they think is correct.

18
00:00:42,150 --> 00:00:45,170
And if it's wrong, they don't
have to feel embarrassed.

19
00:00:45,170 --> 00:00:47,900
And this helps me identify
whether students actually

20
00:00:47,900 --> 00:00:50,210
understand what I'm
lecturing on or not.

21
00:00:50,210 --> 00:00:53,300
I can ask a quick
question saying like,

22
00:00:53,300 --> 00:00:56,760
do you expect this
quantity to go up or down

23
00:00:56,760 --> 00:00:58,700
and then get quick
feedback from students.

24
00:00:58,700 --> 00:01:00,320
They provide their answers.

25
00:01:00,320 --> 00:01:02,780
Poll Everywhere compiles
those and provides me

26
00:01:02,780 --> 00:01:07,382
with a bar graph style output
of what people have answered.

27
00:01:07,382 --> 00:01:08,840
I can provide that
to the students.

28
00:01:08,840 --> 00:01:10,820
I can show what the
correct answer is.

29
00:01:10,820 --> 00:01:13,130
And if they've
answered correctly,

30
00:01:13,130 --> 00:01:14,480
I can say great and move on.

31
00:01:14,480 --> 00:01:16,550
If there's a mix
of answers, I often

32
00:01:16,550 --> 00:01:18,020
have them discuss
in small groups

33
00:01:18,020 --> 00:01:20,120
before asking them again.

34
00:01:20,120 --> 00:01:21,740
In the past, all the
clicker softwares

35
00:01:21,740 --> 00:01:24,540
I've used have only allowed
for simple multiple choice

36
00:01:24,540 --> 00:01:25,040
questions.

37
00:01:25,040 --> 00:01:26,792
But I have started
experimenting with some

38
00:01:26,792 --> 00:01:29,000
of the other styles of
questions that Poll Everywhere

39
00:01:29,000 --> 00:01:33,740
provides like clickable
images or ranking tasks.

40
00:01:33,740 --> 00:01:36,200
Just overall, it's one
of the most intuitive

41
00:01:36,200 --> 00:01:38,150
and aesthetically
pleasing interfaces

42
00:01:38,150 --> 00:01:41,320
that I've used as far
as clicker softwares go.
