Group Work Defined

Working in small groups to solve problems is a great way to learn science. Here are a few documents to give group work some shape and definition so that it can be a self-regulating learning tool:
Group Work Definitions
Group Work Process
Group Work Observer Form
Group Work Recorder Form
Group Work Presenter Grading Form

Important note regarding printing

Before printing turn off the optional header and footer information. Also, make the left margin 0.75 in (1.9 cm) and the other margins 0.5 in (1.3 cm) so that the page breaks I built into the pages work as intended. Use only Internet Explorer or Opera browsers to print as Netscape and Firefox both seem to mess things up a bit.

Some of the files are PDFs and you need the Acrobat Reader available from Adobe. Some files are also MS Word 97 or RTF documents, which just about anyone should be able to view. If you have trouble, try going to to download the Word Viewer.
