what do you call X,

quale sarebbe Y?

15
00:00:19,265 --> 00:00:20,510
and what do you call Z?

Studente: vorrei soltanto

19
00:00:25,877 --> 00:00:26,877
all the knowledge that I've learned
throughout this camp using Quorum

20
00:00:26,877 --> 00:00:27,939
carpire tutto ciò che ho imparato usando Quorum

21
00:00:27,939 --> 00:00:29,079
and maybe develop my own game
maybe later down the line.

22

38
00:00:53,229 --> 00:00:54,137
sono in richiesta

39
00:00:54,137 --> 00:00:56,158
and an understanding
of computing and coding

40
00:00:56,158 --> 00:00:58,179
e conoscere computer e codici

41
00:00:58,179 --> 00:00:59,179
are important for anyone
pursuing these opportunities.

42
00:00:59,179 --> 00:01:00,799
è importante per perseguire nuove

43
00:01:00,799 --> 00:01:02,419
opportunità

44
00:01:02,419 --> 00:01:03,799
But learning programming languages
can be difficult for any new student

45
00:01:03,799 --> 00:01:04,719

Quorum è stato creato

55
00:01:10,716 --> 00:01:11,698
per questo

mi chiamo Andreas Stefik

58
00:01:13,832 --> 00:01:14,521
I'm an assistant professor
of computer science

00:01:15,210 --> 00:01:15,900
at the University of Nevada

00:01:15,900 --> 00:01:18,570
all'università del Nevada a Las Vegas

62
00:01:18,570 --> 00:01:19,570
I invented the Quorum
programming language at first

63
00:01:19,570 --> 00:01:22,210
Ho inventato prima io Quorum

64
00:01:22,210 --> 00:01:23,376
then my wife and I

65
00:01:23,376 --> 00:01:24,543
poi mia moglie ed io

66
00:01:24,543 --> 00:01:25,831
actually created several
versions of it together.

67
00:01:25,831 --> 00:01:26,690
abbiamo dato vita a

68
00:01:26,690 --> 00:01:27,549
varie versioni

69
00:01:27,549 --> 00:01:29,236
It was originally designed
to try to help

70
00:01:29,236 --> 00:01:30,360
è stato progettato

71
00:01:30,360 --> 00:01:31,485
per aiutare

72
00:01:31,485 --> 00:01:32,816
blind or visually impaired students
learn to program more easily.

73
00:01:32,816 --> 00:01:33,703
studenti ciechi e

74
00:01:33,703 --> 00:01:34,295
sordociechi ad imparare

00:01:34,295 --> 00:01:34,887
facilmente

76
00:01:34,887 --> 00:01:36,324
The reason is because at the time
a lot of computer science

77
00:01:36,324 --> 00:01:37,282
il motivo: in questo periodo

78
00:01:37,282 --> 00:01:38,241
la tecnologia

79
00:01:38,241 --> 00:01:39,574
was moving toward
very visual content

80
00:01:39,574 --> 00:01:40,462
sta innovando molti

81
00:01:40,462 --> 00:01:41,351
contenuti visivi

82
00:01:41,351 --> 00:01:41,966
and that in general
makes a lot of sense,

83
00:01:41,966 --> 00:01:42,581
ed in genere

84
00:01:42,581 --> 00:01:43,197
ha molto senso

85
00:01:43,197 --> 00:01:44,035
however, not if you're blind.

86
00:01:44,035 --> 00:01:44,873
a meno che

87
00:01:44,873 --> 00:01:45,711
non si è ciechi

89
00:01:47,067 --> 00:01:48,423
sono Richard Ladner

90
00:01:48,423 --> 00:01:49,939
professor in Computer Science and Engineering
at the University of Washington.

00:01:52,296 --> 00:01:52,845
>> Richard to student: So you really need
similar code

95
00:01:52,845 --> 00:01:53,395
Richard> studente

96
00:01:53,395 --> 00:01:53,945
hai bisogno di un codice diverso

97
00:01:53,945 --> 00:01:55,729
to what you have there already.

98
00:01:55,729 --> 00:01:57,514
da quello che conosci già

99
00:01:57,514 --> 00:01:59,299
>> Richard: Children who are blind,
who can't see,

100
00:01:59,299 --> 00:02:01,850
can actually program in Quorum

101
00:02:01,850 --> 00:02:07,049
and make things that talk
or have sound or have music

102
00:02:07,049 --> 00:02:08,950
so they're not always so visual.

103
00:02:08,950 --> 00:02:13,250
If you look at almost all the tools
that are out there for children,

104
00:02:13,250 --> 00:02:14,690
they're all super visual

105
00:02:14,690 --> 00:02:18,379
and this one is visual and auditory

106
00:02:18,379 --> 00:02:20,560
so that makes it much better
for everybody.

107
00:02:20,560 --> 00:02:24,680
>> Lauren Milne: I'm Lauren Milne
and I'm a graduate student

108
00:02:24,680 --> 00:02:27,580
at the University of Washington
in computer science.

109
00:02:27,580 --> 00:02:28,870
I work with Richard Ladner

110
00:02:28,870 --> 00:02:35,069
and I do a lot of research
in programming languages,

111
00:02:35,069 --> 00:02:38,180
specifically for blind students.

112
00:02:38,180 --> 00:02:45,420
It has full support for screen readers
and Braille displays

113
00:02:45,420 --> 00:02:46,970
and it has a lot of features.

114
00:02:46,970 --> 00:02:50,030
it's very easy to incorporate
audio in programs

115
00:02:50,030 --> 00:02:52,239
and a lot of things you can
play around with in audio

116
00:02:52,239 --> 00:02:54,860
so it means you can
make really accessible,

117
00:02:54,860 --> 00:02:58,370
you can quickly and easily
make accessible games

118
00:02:58,370 --> 00:03:01,490
or whatever you'd like
using Quorum.

119
00:03:01,490 --> 00:03:05,440
>>Narrator: Quorum’s features
are universally designed,

120
00:03:05,440 --> 00:03:08,270
making it an easier language
to learn in general.

121
00:03:08,270 --> 00:03:12,459
>>Andreas: One of the reasons
why Quorum is easier

122
00:03:12,459 --> 00:03:15,430
in some cases for people
to learn and grasp

123
00:03:15,430 --> 00:03:17,799
is because the language is simpler

124
00:03:17,799 --> 00:03:20,440
which impacts people
with learning disabilities.

125
00:03:20,440 --> 00:03:22,780
For example, if I was to
tell the computer

126
00:03:22,780 --> 00:03:25,140
to do something
over and over again

127
00:03:25,140 --> 00:03:27,250
in a language like Java
I would say

128
00:03:27,250 --> 00:03:33,319
for (int i = 0; i < 10; i++) {

129
00:03:33,319 --> 00:03:37,299
Which "obviously" means that
we should do something 10 times.

130
00:03:37,299 --> 00:03:38,640
In Quorum, I say

131
00:03:38,640 --> 00:03:40,099
repeat 10 times.

132
00:03:40,099 --> 00:03:43,349
>>Richard: I find personally
reading Quorum programs

133
00:03:43,349 --> 00:03:47,290
a lot easier than reading
C programs or Java programs.

134
00:03:47,290 --> 00:03:52,730
That I can understand them more easily
and so I feel like there are some

135
00:03:52,730 --> 00:03:54,670
major advantages from the get-go.

136
00:03:54,670 --> 00:03:57,280
Just that simple elegance.

137
00:03:57,280 --> 00:04:02,900
Most languages after every single line
you have to put a semicolon.

138
00:04:02,900 --> 00:04:06,769
Why you have to put a semicolon,
it seems to be just tradition.

139
00:04:06,769 --> 00:04:11,430
It doesn't need to be there
and Quorum has no semicolons.

140
00:04:11,430 --> 00:04:14,269
>> Lauren: I hypothesize
it could be really good

141
00:04:14,269 --> 00:04:17,340
for certain students with
learning disabilities

142
00:04:17,340 --> 00:04:21,720
that Quorum doesn't use braces;
it uses sort of indentations

143
00:04:21,720 --> 00:04:24,680
and it uses the word, keywords instead
to indicate the end of loops.

144
00:04:24,680 --> 00:04:27,090
>> Andreas to students: I want you
to type the word "model"

145
00:04:27,090 --> 00:04:29,630
and then I want you to
type the word "box."

146
00:04:29,630 --> 00:04:35,140
Now there’s a red underline here
because we haven’t added...

147
00:04:35,140 --> 00:04:39,420
>> Narrator: Over the years,
Quorum has gained popularity.

148
00:04:39,420 --> 00:04:44,850
>> Dominic: I'm Dominic and
I'm really into computers

149
00:04:44,850 --> 00:04:47,300
and really enjoy using Quorum

150
00:04:47,300 --> 00:04:52,530
and have used other computer
programs before like C++ and Java.

151
00:04:52,530 --> 00:04:56,430
One of the things that stands out
to me in Quorum is the punctuation

152
00:04:56,430 --> 00:05:00,010
and it's really easy because
you don't have to add in

153
00:05:00,010 --> 00:05:08,190
all the semicolons and all the annoying
hash tags and "@" symbols and everything.

154
00:05:08,190 --> 00:05:12,290
You just use words basically
which is way easier

155
00:05:12,290 --> 00:05:14,600
than using all those
confusing symbols

156
00:05:14,600 --> 00:05:17,980
and I think that makes it easier
for me to program in Quorum

157
00:05:17,980 --> 00:05:19,420
than other languages.

158
00:05:19,420 --> 00:05:22,030
>> Alyssa: Hi, I'm Alyssa.

159
00:05:22,030 --> 00:05:26,010
What makes Quorum easier
is the way they wrote,

160
00:05:26,010 --> 00:05:29,320
the way they program
for us to write the code.

161
00:05:29,320 --> 00:05:32,030
So we don't have
to add semicolons

162
00:05:32,030 --> 00:05:35,350
and brackets and parentheses
and all the stuff.

163
00:05:35,350 --> 00:05:36,470
They made it easier.

164
00:05:36,470 --> 00:05:40,350
You can just type in a word,
"output" let’s say, for example,

165
00:05:40,350 --> 00:05:42,570
and then you could
write in quotes

166
00:05:42,570 --> 00:05:44,630
whatever you want
the computer to say

167
00:05:44,630 --> 00:05:49,220
and that's what makes it
a lot more unique than

168
00:05:49,220 --> 00:05:51,470
other programming languages
like Java.

169
00:05:51,470 --> 00:05:53,220
>> Mary: I’m Mary.

170
00:05:53,220 --> 00:05:57,930
You can do a lot more things
in Quorum with less lines of code

171
00:05:57,930 --> 00:06:01,380
than in some other things
I've used before.

172
00:06:01,380 --> 00:06:04,350
>> Narrator: Quorum is evidence-based,

173
00:06:04,350 --> 00:06:06,600
using the results of
scientific experiments

174
00:06:06,600 --> 00:06:10,050
to determine how to make
the language easier to use.

175
00:06:10,050 --> 00:06:13,420
>> Andreas: Quorum provides
two primary benefits.

176
00:06:13,420 --> 00:06:15,230
One is everything is free

177
00:06:15,230 --> 00:06:17,940
and then number two:
at the end of the day

178
00:06:17,940 --> 00:06:21,220
all of the materials that we use
and that we give to people

179
00:06:21,220 --> 00:06:23,970
are vetted both by
teachers and students

180
00:06:23,970 --> 00:06:27,580
and are vetted in experiments
through the scientific method.

181
00:06:27,580 --> 00:06:30,360
>> Narrator: The result
is a programming language

182
00:06:30,360 --> 00:06:34,220
that is creating a more inviting
environment for computing students.

183
00:06:34,220 --> 00:06:37,720
>> Lauren: A lot of people -
I've seen in intro classes that I've taught.

184
00:06:37,720 --> 00:06:43,240
They come in, you know, and they
get really intimidated at first

185
00:06:43,240 --> 00:06:46,080
when they start programming
and there's all sorts of bugs

186
00:06:46,080 --> 00:06:49,470
and it can be very frustrating.

187
00:06:49,470 --> 00:06:52,830
People drop out and very often
the only people who stick around

188
00:06:52,830 --> 00:06:55,450
are people who have come in,
who come into the college course

189
00:06:55,450 --> 00:06:57,950
with previous programming experience.

190
00:06:57,950 --> 00:07:00,420
Anything that lowers that initial entry

191
00:07:00,420 --> 00:07:05,000
is going to bring a lot more people,
a lot more diversity, because of that.
