This document discusses different online tools for interaction and collaboration: wikis, blogs, discussion boards, and journals. It provides descriptions of each tool and when each one is best used. Wikis allow students to collaboratively create course content. Blogs allow students to showcase their work and comment on each other's posts. Discussion boards provide a space for students to discuss ideas and get feedback. Journals are for private student self-reflection with instructor feedback. The document aims to help participants determine the appropriate tool to use based on whether the goal is group collaboration, individual work, or receiving peer or instructor feedback.
