The use of technology as a means of expression, as constructionists envision. It affords learners to collaborate, and be agents of their learning by creating artifacts that are meaningful to them. Through developing ideas, researching, sharing, and being proud of what they made. It gives learners purpose to use the technology, as they own the c artifacts that represent their identity and that can be shared with a larger community of learners and/or with significant people.
I have particularly thought about Resnick's principle of designing for "low floor- high ceilings and wide walls."
For example, in the Curiously app, there is a component at the end of the experience designed with the purpose that learners reflect or recall their adventure in nature with their caregivers and create a digital or physical artifact together with the data they've gathered or with their imagination, they can create for example; a storybook, a song, a poem, a drawing, a minimovie a photo album, etc... Young learners can start editing an automatically created photo album, while more experienced learners can create their own artifacts from scratch. In order to achieve this, the learning technology must afford progressive ways of fading scaffolding.
