The impact of the Hour of Code

Our annual survey reveals that most students code beyond an hour

We conduct a survey every year after the Hour of Code to discover rough participation demographics, how event organizers experienced the campaign, and more. The results for 2016 are in, and we’ve shared some interesting stats below.

Note: Last week we shared a study that delves into the impact that the Hour of Code has on student confidence and attitudes toward computer science. For that information, go here.

Over 15,000 organizers who participated in Hour of Code 2016 completed our survey and shared their experiences.

A few caveats: The survey was in English only and does not measure the experience of non-English-speaking organizers. The survey was also only sent to event organizers and classroom teachers who registered on the Hour of Code website. Many students or adults engage with the Hour of Code on their own, and their experience is not measured by this survey.

Q: What were the demographics of the participating students?

A: Internationally: 48% female. Among U.S. participants: 38% underrepresented students of color

Why is this important? We’re trying to break stereotypes that limit participation in computer science by girls and underrepresented minorities. The first step in that process is just getting them to try an Hour of Code to see if they like it.

Note: Percentages are calculated based on the participating educators’ reports of total student participation by demographic. Underrepresented minorities are only reported among U.S. participants and include African American, Hispanic/Latino/Latina, Pacific Islander, or Native American/Alaskan Native students.

Q: Overall, how would you rate your Hour of Code experience?

A: 98.1% rated their experience as Good or Great.

Why is this important? We want to know that teachers enjoy their Hour of Code experience. We respect teachers’ time, and know how hard it is to try something new in the classroom.

Q: Where was your Hour of Code event?

A: Events were mostly held in public schools

Why is this important? Public schools in particular reach disadvantaged and underrepresented students who might not otherwise ever try computer science. While anyone can do an Hour of Code anywhere, at any time, we’re pleased to see such widespread adoption within public education — not only in the US, but around the world.

Q: How satisfied were you with your volunteer experience?

A: 97% were satisfied

Why is this important? 17,000 volunteers signed up to help classrooms with their Hour of Code. These volunteers were a mix of software engineers, university students, or interested parents. We’re happy that our teachers had a positive experience inviting these professionals into their classrooms.

Q: Does your school already teach/offer a computer science class that includes programming or coding?

A: 50.6% reported that their school doesn’t offer such a course.

Why is this important? While the number of schools that offer computer science has increased in the last few years, the Hour of Code remains a great introduction for those schools who haven’t been able to support an entire course yet. Roughly half of the teachers who took our survey don’t get any other opportunities to expose their students to computer science.

Q: How has your experience with the Hour of Code affected your interest in teaching computer science?

A: 88.1% said they were”more interested” in teaching CS.

Why is this important? The Hour of Code isn’t just about breaking stereotypes for students — we want to make computer science approachable to teachers, too! Anybody can learn code, and any educator can learn how to teach it.

Q: If given the opportunity, would you continue teaching coding or computer science beyond just one hour?

A: 60% said they would teach computer science if given the opportunity (and 21.7% already started teaching it after a previous Hour of Code).

Why is this important? Most of the Hour of Code organizers are not computer science teachers. In fact, only 15% this year had taught it before the Hour of Code. We’re seeing many teachers from all sorts of backgrounds beginning to teach computer science.

Q: Did any of your students do coding for longer than one hour?

A: 87% of organizers said their students coded for more than one hour

Why is this important? One Hour of Code isn’t enough for a student to really learn any computer science. We just want students to do enough to learn if they like it. And it looks like they do! 87% of teachers said their students went beyond an Hour of Code!

Selected Teacher and Volunteer Testimonials

  • “My class loved it — they wanted more!”
  • “This is my third year doing it with my students, and watching their growth is phenomenal. I love what you are doing and I love being able to inspire and support my female students and my students of color. I love the role models that you provide in the inspirational and instructional videos. Students see themselves in your resources, and that is perfect. Thank you.”
  • “I saw second graders practically jumping out of their chair because they got to do the Hour of Code and 6th graders asking each other if they wanted to code together later! Code.org is leading a movement to get girls and boys from all backgrounds coding and it’s exciting to play a small role through volunteering!”
  • “I believe that this Hour of Code concept is truly amazing. I teach a class with some students with special needs and they flourish in this type of learning. I am impressed with their ability to stay focused and control their behavior while completing the Hour of Code.”
  • “Make it a month instead of an Hour of Code :)”
  • “This year was the best year ever. We went to our Statehouse and had legislators and community partners involved. The website that was created with multiple activities gave students many more options than in the past and was fantastic. It was SO INCREDIBLY helpful to have a clearinghouse page of multiple activities, every student was able to find something they liked.”
  • “I LOVE getting students excited about the possibilities with computer science, especially the younger ones and the girls. It’s like opening up a whole new magic world to them.”
  • “It was fun to watch the kids succeed. Even those who didn’t think they were good at math or logic were able to work through the exercise because they’re presented as fun puzzles, not tedious work.”
  • “I don’t know enough about computer science, but it was so amazing it brought tears to my eyes. It was amazing to hear parents telling me stories about their students going home and coding MORE. I LOVE this movement. I will never be a computer oriented person, I joke that I should’ve been born in the 1800’s but I understand and appreciate the need and demand for computer science. Thank you!!!”
