A big city superintendent called last week and asked for recommendations for K-12 resources for teaching coding and computer science so we reached out to
some folks in the know. Here’s a summary of what we learned:

Hadi Partovi
is CEO of Code.org. As reported in May, he thinks

Teaching kids to code is an economic and social justice issue

. His site is packed with stats that make the case for coding--a good place to start.

Ed Lazowska,
UW, said, “To state the obvious, there is no substitute for a motivated, curious teacher who is empowered to do great things with his/her students. That
said, CodeHS has been looking pretty good to us for an intro course.”

“What’s popular these days is the CS Principles course. These are part of a national effort to revise the Computer Science AP exam. UW has one of these
prototype courses, but probably the Berkeley class is getting most traction.”

“David Malan’s CS50 intro course at Harvard is available online both directly and through edX. It’s a wonderful course,
and David is a superb teacher. I know a number of (smart, motivated) middle teenagers who have loved this course online.”

Lazowska added, “The CS10K community is a good place to start.”

Albert Wenger
, Union Square Ventures, said, "[As an investor] We of course likeCodecademy and they have an afterschool kit.” He added, " Khan Academy also has some good courses.”

Fred Wilson
(Wegner’s partner at USV) helped create the Academy for Software Engineering in NYC and they have an extensive

“The NSF’s Exploring Computer Science is becoming a standard for the intro to CS class in most high schools. That
is often followed by the new AP Principals and then the legacy AP CS class for those who
want to really go deep,” said Wilson.

Rob Hutter,
Managing Partner at Learn Capital, said: “As investors, we’re big believers in CodeHS -- they use a special Javascript framework that Stanford University students have been using to learn computer
science for years and have tuned it for K12 to let kids make games and other high interest interactions. But since it’s based on one of the most popular
object-oriented languages in the real world, CodeHS skills have high transfer to genuine coding tasks. Also it’s getting great traction in schools because
it’s built for the K12 market. Kansas City public schools just did a district-wide deal.”

Hutter also likes CodeNow. “They coordinate a volunteer army of software engineers to mobilize and train inner city
students in code learning with a focus on disadvantaged populations. It’s not a curriculum but a service and they work directly on premise with high need
districts. I couldn’t commend the team there higher for their dedication and mission.” CodeNow launched its six week Summer Fellowship on July 1 with a
class of 20 outstanding NYC students getting smart at NYU.

Tim Brady,
, said (that in addition to CodeHS, which he incubated), said, “You could also include: Scratch from MIT, Codecademy, and Khan Academy has just started offering Computer Science lessons,
as well.” He added, “there is a pretty good list at Code.org.”

Nic Borg
, Edmodo, said, “Two popular apps being used by teachers and students on the Edmodo platform are LearnStreet and ManyLabs’ Arduino Programmer.”

  • LearnStreet provides teachers with tools, content and analytics for teaching JavaScript, Python and Ruby (with Java + HTML/CSS coming in Fall ‘13).
    Teachers can use the LearnStreet course content as well as a library of over 100 fun practice projects.

  • ManyLabs’s provides an Arduino Programmer that enables students to write, save, and share Arduino programs. A Starter Kit is also available which
    includes an Arduino along with a collection of sensors and other devices for your classroom.

Vince Bertram,
Project Lead the Way
, said, “Our Computer Science/Software Engineering course is in pilot for 2013-14 with a full release in fall of 2014. We are working with the College
Board and several industry experts. President Clinton highlighted our new course at CGI in Chicago. It’s getting a lot of attention!”

JD Hoye
, National Acadamies Foundation, said “NAF is currently developing a plan to update its Academy of Information Technology
theme. We envision moving toward a set of pathways within the field, including computer science. We recently had a meeting with a number of top chief
information officers from major high technology companies to get their advice on technology education. Their view was that programming and coding were
important skills with excellent career prospects. Their guidance was to design a program that would initially excite students about developing games or
other applications with less focus on computer languages. Once students are hooked on design and development, they would be more inclined to learn more
about languages and programming.”

NAF’s research, led by Andy Rothstein. Like Brady, he’s a fan of Code.org, Scratch, and Khan Academy. Like Wilson, he likes Exploring Computer and the new AP
Computer Science Principles, “This is being piloted now and will be released in a couple of years.”

Alison Anderson,
Getting Smart
editor, likes Mozilla Webmaker, “Thimble allows anyone to hack websites in a
“sandbox” with a split screen--code on one side, what you’re creating on the other.” She added, “Webmaker has hacker projects that easily work for students. My students enjoyed it the most because they could see the results
of their coding in real time and it allowed the students to interact and get creative with real websites, and seemed to work right at their ability level.


students at Umatilla High School

here in Oregon now have the chance to enroll in a new elective courses using Treehouse- with an extensive library of step-by-step video courses and training exercises, students earn badges by
learning the skills needed to build apps and websites.”

Adam Renfro,
NC Virtual
and Getting Smart blogger, said, “My kids have to use one of these each day:Code Avengers, Codeacademy, Code,Gamestar Mechanic, Scratch,Hackety Hack. And, for the iPad and iPhone Adam recommends:Hakitzu and Cargo-Bot,

“I like Codeacademy the best so far,” said Renfro. Hakitzu and another iPad app called Hopscotch are really great.
If the kids don’t have access to a computer, they use the iPad.

Adam added, “also check out Hacker Scouts,” noting that, “Coding is pretty much an after school event in most

Tricia Moore
, Reynoldsburg City Schools (Columbus OH), said their STEM elementary runsTopCoder competitions (details here). “Students participating in the First Robotics competition learned to program from Java for Dummies plus trial and error. No kidding.”

“At our STEM middle school, students who had demonstrated mastery in the core subjects before the last week of school were able to choose among several
Udacity courses, including computer science, for acceleration,” added Moore. “Job shadowing and other online coursework were also options. My kiddo worked
through a bunch of Codeacademy modules. He wrote a report explaining the different computer languages and why his teachers should use Codeacademy in their
core instruction.”

Reynoldsburg High School eSTEM academy uses Udacity Physics, Calculus, and Computer Science. Ninth grade students rotate
through a 9 week double blocked computer science course using a portion of a Udacity course in a blended presentation with a former computer scientist
teaching it. Fifteen students took the Udacity CS course this summer. School head Marcy Raymond said, “We will also give credit for Coursera through flex credit. Students are able to apply for credit using completion of coursework with Coursera with a
performance or project that demonstrates application of what they have learned.”

Alex Hernandez,
Charter School Growth Fund, agreed with Adam and added (for iPad) Move the Turtle and Hopscotch. Back in browser-land, he like Khan Academy and Code Racer. He also reminded us not to forget physical computing,
for example:

  • Arduino:
    Open-source electronic prototyping platform allowing to create interactive electronic objects

  • LilyPad Arduino
    toolkit: design and create soft, interactive circuits

  • ModKit:
    helps you make (almost) anything smarter



CodeEd, which focuses on teaching computer science to girls, and CoderDojo, an
after-school coding club staffed by volunteers.” Edweek also storified Computer Coding: A Powerful Learning Tool.

Dennis Yang
, Udemy, “We have a great affordable library of coding/CS resources that come along with native apps on iPad and iPhone. We
have private access Udemy for Organizations product if they would like to have more control over their experience.”

Grechen Huebner,
, sent me a note about Kodable, “a tool for parents to help their K-2nd grade child learn the basics of problem solving and programming.” She added, “We’re
already in the app store and are free to download,” with “a curriculum full of additional features designed to help kids learn and adults teach

Kelly Drill
, BotLogic, said “Our dev team is actually working on a new project to help young kids develop the logic/problem-solving
skills they’ll need to eventually learn coding. Kids program a robot to navigate through progressively challenging mazes and can even go head-to-head with
friends in programming tournaments.
