While
models of group investigation like those by Sharan and Sharan (1992) and
others provide students with opportunities to work in-depth and at-length
on a topic or theme of their own choosing, there will be times when the
teacher will draw on a different repertoire of shorter interactive
segments within a class period. Sometimes
called "activators" or "energizers," these tools
provide learners with an opportunity to process information that has just
been presented, read, viewed, or encountered through direct, hands-on
experience.
