contents	Selecting a Web 2.0 Presentation Tool Hodges, Charles B. Clark, Kenneth Elementary Secondary Education Web 2.0 Technologies Evaluation Criteria Evaluation Methods Computer Software Evaluation Technology Uses in Education Library Development Library Services Web-based presentation tools are sometimes referred to as "next generation presentation tools" (EDUCAUSE, 2010). At the most basic level, these tools are simply online versions of traditional presentation software, such as Microsoft's PowerPoint or Apple's Keynote, but some services offer features like web-based collaboration, online presentation sharing, and non-traditional authoring schemes that offer interesting alternatives to the old standards. Online presentation tools, an emerging type of Web 2.0 tool, can be used in many different ways in education. This article covers online presentation tools suitable for K-12 settings and offers an evaluation instrument for selecting the tool that best matches one's skills and needs.
