TWILGO combines Logo with Twitter in that it places a constraint on
the number of characters that can be used. This forces the user to
be systematic and to think about perhaps writing procedures within
procedures in order to devise a more elegant solution to the
problem.
I've recently used TWILGO with KS2 and 3 students and watching the
way that they use the interactivity is extremely insightful. Some
use the TWILGO facility which allows them to try out a string
of instructions, then edit it and try again, to help them to make
successive improvements. Others like to have the whole set of
instructions sorted before they start typing. I found quite a
marked gender difference!!
If you would like to work on programming ideas
without the constraints of Twitter, have a look at the Logo
challenges already on the site. They are a little dated now (
and we have plans to sort that) but there are some worthwhile
activities to encourage your students to think logically and
systematically. Try LOGO
CHALLENGE 1 and work along the challenges from
there.
