Many of the tools explored seem to be rather advanced for Pre-K children and very labor intensive for the classroom teacher. GlobalSchoolNet and Class2Class-math projects seem to be outdated and if anything is recreated they would need to be PK specific.
The tool that I believe to be most usable to get us out of the classroom is to create and then invite participants to Skype. Most likely PK/K teachers in the district and in other districts, possibly a PK center in Aldine.
It is very exciting to help the students to the experience of going global and flattening the walls to the classroom.
