Virtual Presentation

Definitions and background

Virtual presentation software (VPS) such as Microsoft PowerPoint, was originally designed in an effort to organize content and structure lessons as a means to avoid “rambling” (Savasci Acikalin, 2011, p. 340). Often used to share information seamlessly from a computer to a larger screen, VPS has begun to transform the ways in which material is presented by moving away from chalkboards, whiteboards, and overhead projectors (Bartsch & Cobern, 2003). VPS has evolved beyond a way to simply showcase pertinent text, now permitting users to integrate audio, video, illustrations, and animated graphics alongside text to enrich the learning experience (Tangen et al., 2010). VPS is also aligned with the constructivist approach to learning, naturally tapping into different learning styles by disseminating a range of material in numerous ways (Siegle & Foster, 2001).

Given its adoption as a staple for presenters across a range of industries, including the education and business sectors, it is likely that students will one day require the skills to effectively deliver a multimedia presentation in their careers (Christie & Collyer, 2006). Examples of VPS used by educators include Microsoft PowerPoint, Apple Keynote, and OpenOffice (Tangen et al., 2010).

Affordances

VPS enables users to do many things that traditional presentation formats do not (Siegle & Foster, 2001). Technological advancements enable educators to create “rich computer-mediated” lessons (Lai, 2000, p. 200). These lessons effectively feature dynamic sounds, visuals, and text together to successfully communicate complex ideas such as abstract concepts (Lai, 2000). Dringus, Snyder, and Terrell (2010) further observed that incorporating audio statements into virtual presentations (VPs) supported learning by helping to clarify information and improve connectivity between parties at a distance. Lai, Tsai, and Yu (2011) also recognized that VPS allows educators to create two-layer presentations whereby parts of the screen are hidden from the students, yet visible to the instructor. This feature benefits presenters by enabling them to refer to their notes without overwhelming their students with information (Lai et al., 2011).

Siegle and Foster (2001) identified multimedia-based presentation software as a “strong learning tool for educators” that can differentiate learning (p. 35). Broek, Segers, and Verhoeven (2014) further support this argument observing that VPS can be set up to allow students to learn at their own pace. Kablan and Erden (2008) also determined that VPS’ ability to present graphics and text together, as opposed to on separate slides, lessened the cognitive load on students. When students received the information on slides where text and graphics were combined together, students invested significantly less mental effort, learned more efficiently, and demonstrated higher performance when tested (Kablan & Erden, 2008).

Knowing how to successfully implement VPS into a real classroom is also a concern for educators (Yang, Chang, Chien, & Tseng, 2012). Although there is research claiming that the concurrent use of animation, narration, and on-screen text in VPs is redundant, Samur (2012) concluded that this repetition actually has a positive effect on foreign language learners. In a study of non-Turkish speaking student’s, Samur found that adding on-screen text to animated slides with narration led students to remember significantly more vocabulary words than their counterparts. Similarly, Yang et al., (2012) posited that added narration likely helps learners to activate prior knowledge and locate key text.

With time at a premium, educators require tools that are both efficient and effective (Bartsch & Cobern, 2003). Lai et al. (2011) further identified VPS as a time-saving measure, explaining that VPs can be created beforehand, reused often, adjusted as necessary, and stored electronically. Lai et al. also observed that VPs allow presenters to face the audience, helping them to establish and maintain student attention for sustained periods of time.
