A crowdsourced blog post about my SIGCSE Keynote: Computing Education as a Foundation for 21st Century Literacy
I had an unusual (and lazy) idea for my SIGCSE Keynote. I didn’t have the time or energy to write a blog post. How about if I asked everyone to tweet my talk, and I’ll just copy-paste them together? I got a response — too large of a response. There were well over 1000 tweets!
I couldn’t review all of them. I selected a set that covered the key points in the talk, grouped around topics/order in the talk. All the slides are available on Slideshare.net here. A complete “live blogging” account is here.

History of Computer Science and Teaching CS to Everyone
Love that @guzdial uses the Perlis, Newell, and Simon def of CS: "The study of computers and all the phenomena that arise around them" – I use that in #SCRIPT workshops for #CSforALL #sigcse2019 @SCSatCMU

George E Forsythe was cited by Mark @guzdial as the person that coined the term #ComputerScience Here is an article by Donald Knuth outlining Forsythe's contributions: https://t.co/B02bhNHoLT #SIGCSE2019 #SIGCSE19

"If we teach CS in other courses, can we teach enough?" asks @guzdial – I like his analogy to visiting a foreign country: how much of the country's language do you need to know to get by? better to know more, but you don't need to be fully fluent to enjoy your time #SIGCSE2019

From Computational Thinking to Scientific, Engineering, and Historical Thinking
Shout out from @guzdial during the keynote to programs successfully using #computing to help students learn other subjects better – @Bootstrapworld and more. Adding that in South Africa using @OracleAcademy found students’ maths scores improved as a result. #SIGCSE2019 pic.twitter.com/cynKRyLAkT

Now @guzdial is using @gpblocks in his #SIGCSE2019 keynote (cc @moenig) to display real-time visualisation of sound waves and fourier transform as an example of aiding learning via programming. He has a harmonica, and his ukulele is presumably hidden behind the podium…

If we want to get computing education to everyone, we need to increase our efficiency in teaching it – @guzdial #SIGCSE2019

I had several requests for the code I ran in the demo in JES (which is available here):
def increaseVolume(sound):
for sample in getSamples(sound):
value = getSampleValue(sample)
setSampleValue(sample, value * 4)
def maximize(sound):
for sample in getSamples(sound):
value = getSampleValue(sample)
if value >= 0:
setSampleValue(sample,32600)
if value < 0:
setSampleValue(sample, -32600)
The sound visualization GP project is here.
You can get GP at http://gpblocks.org.

There's a lot of programming paradigms we haven't tried yet in K-12. What about theorem solvers, logic programming, etc? We need to grow and mutate, and not just use technologies that work for software engineers. – @guzdial #SIGCSE2019

Q & A
Mark @guzdial during Q&A:
Q: Should every college student take CS0?
A: No. I agree with Perlis: every student should take some programming.
Not the same course the future software developers are going to take.
A course that makes sense to them.#SIGCSE2019 #SIGCSE19— Phill Conrad (@pconrad) March 1, 2019
If all university graduates knew something about programming, we create a literate culture, and that will make future young people want to learn programming. And, all pre-service teachers would know something about programming! –@guzdial #SIGCSE2019
— Katie Cunningham (@katieirenec) March 1, 2019
Ok this is food for thought: @guzdial believes every UG student needs to know programming, but not CS. “This is how we create a computational culture. If you want CS in elementary schools, start with the university.” #SIGCSE2019 #CSforALL pic.twitter.com/tjqJunzSnc
— Diane Levitt (@diane_levitt) March 1, 2019
We go to teachers and say ‘here’s the tool’, it’s very rare for us to go to then and ask ‘what do you want in a tool?’ – @guzdial at #SIGCSE2019
— Miles Berry FCCT (@mberry) March 1, 2019
CS "in their own language, in their own terms"– @guzdial #SIGCSE2019
A statement that goes beyond the immediate context of integration into school disciplines. What would CSed look like on people's own terms and in their own languages? #translanguaging

Draw on research in science education and maths education to move cs education forward + we need more people in schools of education @guzdial at #SIGCSE2019 – agree 100% on both points!!
