  Student difficulties in learning Physics have been thoroughly discussed in
the scientific literature. Already in 1980, Papert complained that schools
teach Newtonian motion by manipulating equations rather than by manipulating
the Newtonian objects themselves, what would be possible in a 'physics
microworld'. On the other hand, Second Life and its scripting language have a
remarkable learning curve that discourages most teachers at using it as an
environment for educational computer simulations and microworlds. The objective
of this work is to describe TATI, a textual interface which, through TATILogo,
an accessible Logo language extension, allows the generation of various physics
microworlds in Second Life, containing different types of objects that follow
different physical laws, providing a learning path into Newtonian Physics.
