>> Instructor: If you’re a camera, a 3D camera,
istruttore: se sei una videocamera in 3D
and you’re looking at her,
e la stai guardando.
puntando in quella direzione.
and she’s pointing in that direction,
la domanda é:
what do you call X,
quale sarebbe x?
what do you call Y,
quale sarebbe Y?
and what do you call Z?
e quale sarebbe Z?
>> Student: I would want to take
Studente: vorrei soltanto
all the knowledge that I've learned throughout this camp using Quorum
carpire tutto ciò che ho imparato usando Quorum
and maybe develop my own game maybe later down the line.
e sviluppare tutte le mie conoscenze,su questa linea
>> Student: I really want to teach others.
Studente: voglio insegnare ad altri
That’s sort of what I like to do
tutto ciò che mi piace fare
and with Quorum I can do that much easier.
e grazie a Quorum posso farlo facilmente

>> Instructor: We’re now going to say "box."
istruttore: ora stiamo dicendo
"box"
>> Narrator: Technology jobs are in demand
I lavori con la tecnologia
sono in richiesta
and an understanding of computing and coding
e conoscere computer e codici
are important for anyone pursuing these opportunities.
è importante per perseguire nuove
opportunità
But learning programming languages can be difficult for any new student
Ma apprendere nuovi
linguaggi di programmazione
è difficile
including some students with disabilities.
anche per studenti
disabili
That’s why Quorum was created.
Quorum è stato creato
per questo
>> Andreas Stefik: My name is Andreas Stefik.
mi chiamo Andreas Stefik
I'm an assistant professor of computer science
sono assistente professore
at the University of Nevada at Las Vegas.
all'università del Nevada a Las Vegas
I invented the Quorum programming language at first
Ho inventato prima io Quorum
then my wife and I
poi mia moglie ed io
actually created several versions of it together.
abbiamo dato vita a
varie versioni
It was originally designed to try to help
è stato progettato
per aiutare
blind or visually impaired students learn to program more easily.
studenti ciechi e
sordociechi ad imparare
facilmente
The reason is because at the time a lot of computer science
il motivo: in questo periodo
la tecnologia
was moving toward very visual content
sta innovando molti
contenuti visivi
and that in general makes a lot of sense,
ed in genere
ha molto senso
however, not if you're blind.
a meno che
non si è ciechi
>> Richard Ladner: I'm Richard Ladner,
sono Richard Ladner
professor in Computer Science and Engineering at the University of Washington.
professore di Informatica ed
Ingegneria
all'università di Washington
>> Richard to student: So you really need similar code
Richard> studente
hai bisogno di un codice diverso
to what you have there already.
da quello che conosci già
>> Richard: Children who are blind, who can't see,
can actually program in Quorum
and make things that talk or have sound or have music
so they're not always so visual.
If you look at almost all the tools that are out there for children,
they're all super visual
and this one is visual and auditory
so that makes it much better for everybody.
>> Lauren Milne: I'm Lauren Milne and I'm a graduate student
at the University of Washington in computer science.
I work with Richard Ladner
and I do a lot of research in programming languages,
specifically for blind students.
It has full support for screen readers and Braille displays
and it has a lot of features.
it's very easy to incorporate audio in programs
and a lot of things you can play around with in audio
so it means you can make really accessible,
you can quickly and easily make accessible games
or whatever you'd like using Quorum.
>>Narrator: Quorum’s features are universally designed,
making it an easier language to learn in general.
>>Andreas: One of the reasons why Quorum is easier
in some cases for people to learn and grasp
is because the language is simpler
which impacts people with learning disabilities.
For example, if I was to tell the computer
to do something over and over again
in a language like Java I would say
for (int i = 0; i < 10; i++) {
Which "obviously" means that we should do something 10 times.
In Quorum, I say
repeat 10 times.
>>Richard: I find personally reading Quorum programs
a lot easier than reading C programs or Java programs.
That I can understand them more easily and so I feel like there are some
major advantages from the get-go.
Just that simple elegance.
Most languages after every single line you have to put a semicolon.
Why you have to put a semicolon, it seems to be just tradition.
It doesn't need to be there and Quorum has no semicolons.
>> Lauren: I hypothesize it could be really good
for certain students with learning disabilities
that Quorum doesn't use braces; it uses sort of indentations
and it uses the word, keywords instead to indicate the end of loops.
>> Andreas to students: I want you to type the word "model"
and then I want you to type the word "box."
Now there’s a red underline here because we haven’t added...
>> Narrator: Over the years, Quorum has gained popularity.
>> Dominic: I'm Dominic and I'm really into computers
and really enjoy using Quorum
and have used other computer programs before like C++ and Java.
One of the things that stands out to me in Quorum is the punctuation
and it's really easy because you don't have to add in
all the semicolons and all the annoying hash tags and "@" symbols and everything.
You just use words basically which is way easier
than using all those confusing symbols
and I think that makes it easier for me to program in Quorum
than other languages.
>> Alyssa: Hi, I'm Alyssa.
What makes Quorum easier is the way they wrote,
the way they program for us to write the code.
So we don't have to add semicolons
and brackets and parentheses and all the stuff.
They made it easier.
You can just type in a word, "output" let’s say, for example,
and then you could write in quotes
whatever you want the computer to say
and that's what makes it a lot more unique than
other programming languages like Java.
>> Mary: I’m Mary.
You can do a lot more things in Quorum with less lines of code
than in some other things I've used before.
>> Narrator: Quorum is evidence-based,
using the results of scientific experiments
to determine how to make the language easier to use.
>> Andreas: Quorum provides two primary benefits.
One is everything is free
and then number two: at the end of the day
all of the materials that we use and that we give to people
are vetted both by teachers and students
and are vetted in experiments through the scientific method.
>> Narrator: The result is a programming language
that is creating a more inviting environment for computing students.
>> Lauren: A lot of people - I've seen in intro classes that I've taught.
They come in, you know, and they get really intimidated at first
when they start programming and there's all sorts of bugs
and it can be very frustrating.
People drop out and very often the only people who stick around
are people who have come in, who come into the college course
with previous programming experience.
Anything that lowers that initial entry
is going to bring a lot more people, a lot more diversity, because of that.
