There are various tools out there that allow individuals to post a layout to his/her presentation and/or workshop. If one is looking for a basic outline tool, Power Point and Word are sufficient. The next link leads individuals to a mind mapping tool that I have used in EDUC-8847 and others at Walden University. This interactive tool allows the individual to post thoughts on a subject, any subcategories, and so on and so forth.
