This document outlines a workshop on evaluating the impact of collaborative Web 2.0 tools on student motivation and incidental learning. The workshop objectives are to define collaborative Web 2.0 tools and incidental learning, identify where incidental learning may occur using these tools, select appropriate tools for different learning environments, and demonstrate how incidental learning impacts social collaboration and motivation. Examples of collaborative tools discussed include blogs, Google Docs, Prezi, and VoiceThread. The presentation aims to show how these tools can increase student engagement, promote incidental learning without compromising intentional learning, and personalize instruction.
