Hello World is a computer science club at a high school in Illinois where students develop mobile applications to learn science.
The club’s 30 members rely on Team Treehouse resources for instruction. “It’s exciting because each student can study at their own pace,” faculty adviser Tesa Edwards said. “If they need to, they go back and study a video again until they get it.”
The month-old Hello World computer science club at Highland Park High School has more than 30 underclassmen in a school lab learning to write code for mobile apps, with new members joining every week.
The club and its free-style study model is the brainchild of freshman Ethan Eirinberg, who asks more questions of himself and others than Alex Trebek in a round of Jeopardy.
Eirinberg said a teen’s idea of a cool app is “Snapchat,” which allows a user to text a photo for friends to enjoy — after which the images disappear and aren’t downloadable. Also popular are apps like Instagram, Alien Blue, Unblock Me and Subway Surfers, according to a quick poll of club members.
Two years ago Eirinberg was fascinated by older brother Dylan’s success in creating an iPhone app for a simple game.
“He needed tons of lines of code to do it,” said Eirinberg. “He read three books to learn how to program a simple game and I kind of questioned that. The books were so dry that I couldn’t connect with anything.
“I didn’t want to learn how everything worked; I wanted to create a finished product and get it out there,” said Eirinberg, now 15.
