10=E2=80=9317 create their own videogames by combining drawn characters wit=
h a set
of visual icons =E2=80=94 no typing required. The icons compose like cards,
activating behaviours in the drawn objects and naturally leading kids
through concepts such as categories, rules, recursion, and metaprogramming.

In this talk I'll show how Smalltalk's live, image-based environment made
it uniquely suited for building Di=C3=A1logo. I'll give a demo of the app, =
walk
through some implementation metrics, and discuss the pedagogical ideas
behind the project =E2=80=94 including a free 7-class course I've shared on=
line and
workshops I've run open to the community at the Faculty of Exact Sciences
(UBA).

Agust=C3=ADn Mart=C3=ADnez is a developer and researcher at the Universidad=
 de Buenos
Aires (UBA), and the creator of Di=C3=A1logo, a programming environment for
children built in Cuis Smalltalk. He presented a paper on Di=C3=A1logo at t=
he
Onward! track of OOPSLA, and has given public talks at Nerdearla,
Argentina's largest tech community event.

This will be an online meeting.
