Presentation tools are increasing in popularity and providing powerful tools for creation of instructional materials and accessible information in audio-visual formats. When used appropriately, these tools can support and extend traditional presentations in valuable ways. In lecture settings, Microsoft PowerPoint, for example, has become the dominant presentation tool because it is both readily available and easy-to-use by instructors (Grabe & Grabe 2007). It allows instructors to create and manipulate presentations in a wide variety of contexts that can enhance students’ interests and engagement (Mills & Roblyer, 2006).Presentation tools help instructors clearly identify the main points of a topic or activity while still providing the details through presentation (Loisel & Galer, 2004). Instructors can incorporate multiple types of media formats (e.g., diagram, photo, drawing, sound, animation, video, etc.) that cannot be easily integrated together into one single medium.

Parette, Blum, Boeckmann & Watts (2009) suggested that regardless of such concerns and problems related to the use of presentation tools, like PowerPoint, it is no longer an issue of whether to use them or not. Instead, instructors must focus on how they can successfully use them inside and outside classrooms to support learners (Parette et al., 2009)

Flickr is a photo management and sharing online application that provides a place to share photos and meet people with similar interests, even if photography is not their focus. Using Flickr, users can upload, download, tag, rate, and c om ment on photos. Users can manage and organize images, and create private or public groups to cultivate a sense of c om munity. Flickr offers a vast collection of images that are not available elsewhere, and its collaborative tools have made it popular in higher education. Flickr contains imagery that can be used in teaching to help develop visual literacy skills. University instructors have begun using Flickr images in their courses to share, critique, and analyze visual information. In addition, the design of Flickr intentionally promotes the development of community. The ability to engage users in a conversation about a photo, and to u...
