Student-developed apps

Grader A: hit

Google/Gallup: 40% of US schools offered a CS class with programming in 2016 (25% in 2015); intro curricula of the period (Code.org App Lab, MIT App Inventor, AP CS Principles from 2016) have students build apps. App-building as distinct from programming is not separately measured.

Test: at least 5% of US schools had students building programs/apps by 2017 (abstract-practice test)

• More K-12 Computer Science Classes Teach Programming/Coding (Gallup) (2016): 40% of US K-12 principals report a CS class with programming/coding

Grader B: hit

AP Computer Science Principles (launched 2016-17) requires a Create task in which each student builds a program, often an app (App Inventor, App Lab); offered in about 3,700 schools in 2017, roughly 15% of US high schools. Hour of Code and App Lab extend this further.

Test: Practice test: routine in at least 5% of (high) schools by 2017.

• Participation in AP Computer Science Principles Grows Again (2018-06): Schools offering AP CSP rose from about 2,500 (2016) to 3,700 (2017)
• AP CSP Performance Task (n.d.): Create task requires students to develop their own program
