Compared to professional programmers, end-user programmers...
How can we empower everyone to access and explore their personal data (e.g from social media)?
How can he help everyone develop the concepts and language they need to understand data science (e.g., to communicate and collaborate effectively with data science professionals)?
Train end-user data scientists who can ask and answer questions using Python and web data.
Morning: Interactive lecture in iPython & Terminal
Afternoon: Independent work on projects
class, object, method, recursion, list comprehension, unit testing
Edit per day in English Wikipedia to all articles in the category “People shot dead by law enforcement officers.” (Work done by Mary Dickson during Session #3 of the Fall 2014 Community Data Science Workshops.)

“As you’re leveling up your skills, you can keep track of progress right on the dashboard. Points, badges, and skill levels are all visible and updated in realtime.”
|Project metadata||User metadata||Site-wide statistics|
Approx. four-month of user testing
2,500 active Scratch users invited
Approx. 700 active users with ~1600 projects
Online ethnographic observations of activity (projects, comments, and forum posts)
Interviews, surveys, and face-to-face workshops
Doughnut chart showing the types of blocks the viewer of the project has used in their previously shared projects.
Number of scoops of icecream on the cone is determined by the number of followers of the viewer.
“I was thinking about how I could use it to show statistics of how many followers and things you have, like not just in a bar chart”

Project that gives the viewer a “talkativeness” score based on the cumulative string-length of titles and descriptions of projects the viewer has shared in the past.
Project that lets the viewer “buy” virtual accessories for their virtual doll. The buying power (amount of “money”) is determined by the number of shared projects or followers.
“I was trying to think of something that, somebody hadn’t done yet, and I didn’t see that. And also I really like to do art on Scratch and that was a good opportunity to use that and mix the two together.”

“[…] it does feel like a bit of a way to stalk Scratchers from a project. Though I suppose it doesn't make much of a difference since a stalker could always just stalk them on the site, but you get what I mean. Someone could set themselves up with some of these blocks and get themselves a constant relay of the person’s activity.”

“I love these new Scratch Blocks! However I did notice that they could be used to exclude new scratchers or scratchers with not a lot of followers by using a code: like this:
when flag clicked
if then user's followers < 300
I do not think this a big problem as it would be easy to remove this code but I did just want to bring this to your attention in case this not what you would want the blocks to be used for”

Democratizing data science is about helping individuals' follow their interests with data, not about learning data science as an end in itself. End-user data scientists have broad and surprising interests.
They require different tools and different form of support.

“ At one point the follower blocks, it said I have slightly more followers than I do. And, that was kind of confusing when I was trying to make the project. […] I pulled up a second [browser] tab and compared the [data from Scratch Community Blocks and the data in my profile]. ”

Commenter A: that's so cool! almost 00.5% of all the users on scratch have viewed my projects and that's a lot :B but crossstitch’s results are indeed slightly dubious… over 100% of people have viewed his projects which is awesome but impossible - love the project!! ^o^
Commenter B: @CommenterA i think it's because its based on views, not each specific player.
Commenter A: @CommenterB that's awesome :D people who haven't registered on scratch have viewed a significant amount of his projects yes
Project Creator: @CommenterA Yeah what @CommenterB said is correct
“This project does not and cannot calculate unique viewers. So some views can be the exact same person who viewed the project earlier.”
“I think this was a great idea! I am just a bit worried that people will make these projects and take it the wrong way, saying that followers are the most important thing in on Scratch. […]”
