Just a note of caution. Elementary grades are where students pickup fluency in
writing and reading. I hear teachers, even in USA, face students who are yet
to become fluent in reading/writing to use programs like Etoys meaningfully.
Try using Etoys with dingbat fonts for a week to understand how it feels to a
Elementary grade students are intensely physical. They learn more through
movements, touch and sounds than through sight. If "teaching" means 'reaching
out to >80% of learners' then abstract models like Etoys or Pen/Paper can only
supplement more concrete learning aids.
