QR code stands for quick response code,
1
6506
2680
00:09
and it's a two-dimensional bar code
2
9210
1583
00:10
that holds a good deal more information
3
10817
1869
00:12
than a traditional bar code.

00:14
They originated in Japan at the Toyota factory
5
14068
2924
00:17
to track the manufacturing of car parts.
6
17016
2787
00:19
Since then, they've taken off in popularity,
7
19827
2705
00:22
and you'll see them everywhere in consumer advertising.

When you scan a QR code, you're instantly taken
9
25688
3175
00:28
to a variety of tech-based experiences:
10
28887
2900
00:31
Could be a text message,
11
31811
1435
00:33
could be an audio message,
12
33270
1371
00:34
could be a website,
13
34665
1382
00:36
could be a video.
14
36071
1230
00:37
It's like magic.
15
37325
1554
00:38
The tools to create a QR code are essentially free,
16
38903
3351
00:42
and the tools to interact with the QR code
17
42278
2000
00:44
are increasingly easy and common to use.
18
44302
3332
00:47
So, we have this great, free, easy tool,
19
47658
2453
00:50
but what can we do with it?
20
50135
1635
00:51
Teachers have realized there's a lot of potential
21
51794
2632
00:54
for QR codes in the classroom.
22
54450
2152
00:56
Recently, I told my class we would be learning
23
56626
2191
00:58
some new vocabulary words,
24
58841
1438
01:00
something we do two or three times a month.
25
60303
2485
01:02
They let out a groan
26
62812
1405
01:04
because it's kind of a boring activity.
27
64241
2416
01:06
Then, I passed out QR codes to all my students
28
66681
2734
01:09
and told them we'd be interacting with them with devices,
29
69439
2715
01:12
and that's how they'd find their vocabulary list.
30
72178
2339
01:14
The attitude in the class changed completely.
31
74541
3005
01:17
They went from groaning and moaning
32
77570
1667
01:19
to excited and enthusiastic.
33
79261
2575
01:21
I could teach the exact same lesson using QR codes
34
81860
3049
01:24
and not using QR codes
35
84933
1665
01:26
and get a completely different attitude.
36
86622
2561
01:29
One fun activity to do with QR codes
37
89207
1977
01:31
is a scavenger hunt.
38
91208
1436
01:32
I create QR codes with tasks assigned to them.
39
92668
2770
01:35
I hide them all around the room.
40
95462
1854
01:37
Students go with their devices
41
97340
1429
01:38
and scan them and have to complete the task.
42
98793
2443
01:41
Recently, I hosted a technology event at my school
43
101260
2381
01:43
and held a school-wide QR code.
44
103665
2701
01:46
Students loved it.
45
106390
1728
01:48
In grades K through 6,
46
108142
1268
01:49
they were completely engaged and excited,
47
109434
2062
01:51
literally running from code to code
48
111520
1667
01:53
because they were so excited
49
113211
1417
01:54
to see what the next task was going to be.
50
114652
2687
01:57
Students who didn't have devices with them
51
117363
1286
01:58
were begging their parents
52
118673
1416
02:00
to pull out their smart phones
53
120113
1429
02:01
so they could participate as well.
54
121566
1819
02:03
It was so refreshing to see
55
123409
1512
02:04
that level of enthusiasm and excitement regarding learning.
56
124945
4579
02:09
A creative use for teachers for QR codes
57
129548
2402
02:11
is for positive reinforcement.
58
131974
2146
02:14
Put up a poster in your classroom
59
134144
1634
02:15
with numbered QR codes,
60
135802
1384
02:17
each one leading to a different message.
61
137210
1905
02:19
When a student needs some feedback,
62
139139
1667
02:20
tell him, 'Go scan number 5.'
63
140830
1536
02:22
'Go scan number 22.'
64
142390
1647
02:24
And the message will say,
65
144061
1011
02:25
'Great job today! I love your enthusiasm.'
66
145096
2770
02:27
'Nice work! I can see you're working really hard.'
67
147890
2561
02:30
It's so much more exciting for a student
68
150475
1966
02:32
to get out of their seat,
69
152465
1366
02:33
scan a code,
70
153855
1070
02:34
and interact with something
71
154949
1347
02:36
for then the teacher just to say, 'Good job!'
72
156320
2857
02:39
It's much more memorable.
73
159201
1220
02:40
Libraries have endless uses for QR codes:
74
160445
3250
02:43
scannable book reviews,
75
163719
2514
02:46
lists of reading suggestions
76
166257
1951
02:48
and book lists on the walls,
77
168232
1780
02:50
biographies.
78
170036
1189
02:51
Imagine pulling a biography
79
171249
1286
02:52
of Martin Luther King, Jr. off the shelf,
80
172559
2041
02:54
scanning a QR code,
81
174624
1187
02:55
and being instantly taken
82
175835
1314
02:57
to the "I Have a Dream" speech.
83
177173
1721
02:58
It literally makes learning come alive.
84
178918
3064
03:02
QR codes can add a nice 21st century twist
85
182006
2231
03:04
to a traditional assignment.
86
184261
1643
03:05
Each year, I have my class
87
185928
1657
03:07
create a poster for a book report,
88
187609
2007
03:09
something we've all probably done
89
189640
1311
03:10
at some point in elementary school.
90
190975
1853
03:12
It's a little bit of a boring assignment.
91
192852
1978
03:14
The kids enjoy it okay.
92
194854
1514
03:16
This time, I changed it up,
93
196392
1479
03:17
and the second step of the assignment
94
197895
1762
03:19
was to have them record their voices,
95
199681
2147
03:21
recording an audio QR code of themselves
96
201852
3357
03:25
giving a book review of the book.
97
205233
2014
03:27
They then printed the QR code,
98
207271
2198
03:29
attached it to the poster,
99
209493
1341
03:30
and gave the poster a hands-on, interactive quality.
100
210858
3253
03:34
We put them in the hallway
101
214135
1241
03:35
and kids from all different classrooms
102
215400
1609
03:37
were walking by, scanning them,
103
217033
1263
03:38
listening to these book reviews.
104
218320
1675
03:40
It was so much more fun
105
220019
1244
03:41
than just a traditional poster.
106
221287
2176
03:43
My class recently had the privilege of participating
107
223487
3146
03:46
in a QR code lesson
108
226657
1243
03:47
led by a teacher across the country.
109
227924
2540
03:50
If the video chat weren't exciting enough,
110
230488
2993
03:53
the fact that she incorporated QR codes into the lesson,
111
233505
3154
03:56
my students, from their seat,
112
236683
1678
03:58
from the comfort of their classroom,
113
238385
1715
04:00
could actually scan the codes on the computer screen,
114
240124
2540
04:02
interacting with her QR codes from 3,000 miles away,
115
242688
3313
04:06
was incredibly exciting and memorable for my students.
116
246025
3479
04:09
They did not stop talking about the lesson for weeks.
117
249528
3043
04:12
You just don't get that kind of memorable,
118
252595
2407
04:15
engaging experience using a worksheet
119
255026
2995
04:18
or reading from a textbook.
120
258045
2081
04:20
QR codes have a possible use
121
260150
2493
04:22
in every grade level,
122
262667
1763
04:24
with every subject area.
123
264454
1796
04:26
Kindergarten teachers can have their students
124
266274
2143
04:28
scan a QR code that leads to a phonics lesson.
125
268441
3079
04:31
The music teacher can create audio QR codes
126
271544
2752
04:34
of their students playing instruments or singing.
127
274320
2975
04:37
PE teachera can post real-time race results
128
277319
2424
04:39
or athletic event results,
129
279767
1728
04:41
all attached to a QR code.
130
281519
1944
04:43
The student council or the PTO can advertise
131
283487
2813
04:46
upcoming school events all around the school
132
286324
2718
04:49
and send home on flyers via QR code.
133
289066
3036
04:52
The possibilities with this free and easy tool are endless.
134
292126
3747
04:55
If used properly, QR codes have the potential
135
295897
3165
04:59
to awaken a student,
136
299086
1311
05:00
transform a lesson,
137
300421
1219
05:01
and bring down the walls of your classroom,
138
301664
2771
05:04
creating the ultimate 21st century learning opportunity.
