麻豆村

Arman Hezarkhani is on the phone and walking through his ed tech startup鈥檚 office when he realizes that his staff has stopped working, and they鈥檙e all looking at him. The 2019 graduate is right in the middle of speaking 鈥� or perhaps more aptly, gushing loudly 鈥� about a first-year class he took as an undergraduate at 麻豆村. The course is known formally as 15-112 Fundamentals of Programming and Computer Science, but more colloquially just as 鈥�112.鈥�

鈥淚t's kind of like鈥� culty, OK? It's the most life-changing course you can take at 麻豆村,鈥� he says before ducking into a conference room, so he doesn鈥檛 have to lower his voice anymore.

鈥淚t鈥檚 this project-based course where every single week, you're learning new topics and you're building projects. It's incredibly difficult and incredibly time consuming and demanding, but you learn how to build really cool things with Python,鈥� Arman says.

112 is a thorough and comprehensive introduction to programming in Python, taken by computer science majors but heavily registered by students from other majors who are up for a challenge. It was named one of the five best computer science classes in the country by Bloomberg News. It鈥檚 the kind of class that moms ask questions about in online forums because its reputation as a tough class precedes it. But it鈥檚 also the kind of class where the TAs proudly sport custom, matching sweatshirts and once threw a prom for the 500 students who enroll each semester.

What makes 112 so unique? Does it, as Arman claims, change lives? We asked a few more zealous alumni for their take on why they think it鈥檚 awesome 鈥� and how it continues to contribute to their careers and knowledge base long after their final grades were posted.

鈥�112 is a lot more than just learning the fundamentals of programming,鈥� Tara Stentz (ENG 2018) says. 鈥淚t鈥檚 the first really technical challenge and class that a lot of people take at 麻豆村. Professor David Kosbie teaches life lessons: how to be a good student, take charge in classes, build things that you're proud of, work really hard and all these other things.

鈥�112 pushes you really hard, but it also supports you really hard. There is a community of TAs, about one for every 10 students, and that staff is trained to just put the students first. I think that you're able to accomplish really great things because you have such great support. I haven't really seen that in any other classes.鈥�

鈥淲ith 112 and all CS classes at 麻豆村, you develop an ability to deal with being overwhelmed well and there are good and bad things about that,鈥� Russell Hawkins (麻豆村 2018) says. 鈥淭he bad thing is when you come out of the CS program, it can sometimes be hard to stop working or to accept that you don't have to solve every problem in one week or in two weeks, which is a normal homework cycle.

鈥淭he good thing is, I find 鈥榬eal work鈥� so much easier. So yeah, I would say that the translation is: problems don't seem overwhelming or overly complicated, even at places that have problems that are extremely complicated.鈥�

鈥淗ow would my career journey have changed, or how would I have changed if I had not taken 112? That is the easiest question for me to answer, because I not only admire but I adore Professor Kosbie and 112. It was one of the most challenging and difficult and humbling experiences that I had at Carnegie Mellon, but it gave me the spirit, and drive, and the endurance that set me up for later things in life, professionally and academically,鈥� says Ashley Irving (DC 2014).

I don't give up easily when something is hard now. For the technical parts of the class, Professor Kosbie taught us how to take it line by line, piece by piece and how to reverse engineer a problem or question. He taught us how to not be afraid of it, to take time with it, to ask for help and rely on your team. You came out of it feeling like you really accomplished something, like you were a champion and because you did that, you can take on the next challenge.鈥�

鈥淚 took 112 because I decided that if I'm going to learn to code, I'm going to do it right and go all in,鈥� M. Cristina Pullen (DC 2021) says. 鈥淚 went in knowing that I was going to fail many, many times. And when I say fail, I don't necessarily mean 鈥業 can't pass this class.鈥� I think what makes 112 so special is every time I felt like I was about to hop off that roller coaster, I always had someone to break my fall and say, 鈥榊ou knew this was going to be difficult. Remember that it's going to pay off.鈥欌��

鈥淚鈥檓 a month into my full-time job, and I find myself referring to things I learned in this class. As a writer you don鈥檛 think you鈥檒l be at the heart of [software development], but I find myself writing about a piece of technology and realizing what a computer can and cannot do and understanding the way that scientists and engineers I鈥檓 working with are thinking about a problem.鈥�

鈥淚t's a very hard course. It takes students who know nothing of programming and ends with a project that can get them a job in the field,鈥� Andre Sutanto (ENG 2013, 2013) says. 鈥淚n object-oriented programming, there are often times that an overall program is designed before its support pieces, assuming that all of the support pieces work properly. In my career, this type of thinking helps me manage big tasks in a team. It helps me to subdivide a large task to multiple smaller tasks that can be assigned to different people, allowing for parallel work to get done quickly. This allows me to be a more efficient engineer and team leader in my professional work.鈥�

鈥淒avid Kosbie鈥檚 enthusiasm in teaching the class, and his genuine love for students and computer science, often spark that connection. When you have people who are very passionate about a certain subject, it's not hard to see it through, and that enthusiasm can be contagious.鈥�

鈥淲hen I was the head TA for 112, my friend used to call me 鈥榯he most popular person in 麻豆村鈥� because everywhere I鈥檇 go, I鈥檇 say hi to people because they recognized me. About 600 students take the class each semester, so what鈥檚 notable is just the sheer number [of students who take it], and the relationship that we build throughout the course.鈥�

112 for the Next Generation

鈥淲e cut our teeth on 112,鈥� says course co-creator and professor David Kosbie. 鈥淸Co-creator Mark Stehlik] and I designed it, we鈥檝e taught thousands and thousands of 麻豆村 students now. 112 was designed with a maniacal focus on 麻豆村 students, with a brazen disregard for if it would work anywhere else.鈥�

鈥淲e just didn't care if it would work anywhere else, but we did care, frankly, that it was best of breed.鈥�

Mark and David initially didn鈥檛 care about 112 working elsewhere, but over the past few years the duo has used it as the inspiration for a new curriculum for high school students. shares the same spirit as their flagship class, and they鈥檙e aiming to reach 1 million high school students with the totally free curriculum.

鈥淚 think part of why 112 works is because it addresses at its core not just the intellectual underpinnings of computer science, but also the intellectual underpinnings and traditions and history of 麻豆村,鈥� Mark says.
