I plan to use App lab from code.org for a stage 4 Technology Mandatory (NSW) Class. The API involves both options for block programming and text programming in javascript.

Students would complete the Introduction to App Lab Course and then develop a simple App and design folio including algorithms using App lab. Australian Curriculum outcomes: ACTDEP038, ACTDIP027, ACTDIP031, ACTDIP029, (ACTDIP026
