Asynchronous instruction has its roots in early forms of distance education such as correspondence schools (Keegan, 1996); communication was truly asynchronous because of postal delays (Bernard et al., 2004, p. 387). Asynchronous instruction occurs in delayed time and does not require the simultaneous participation of students and teacher (Rovy & Essex, 2001; Sabau, 2005). Students experienced learning events independently and learning is not synchronized in time or space.
Although asynchronous voice conferencing has proven useful in some instructional contexts (Mclntosh, Braul, & Chao, 2003), text-based conferencing is widely implemented in post-secondary education (Berge, 1999; Romiszowski & Mason, 2004; Tu & Corry, 2003) and is synonymous with asynchronous online discussion (Fjermestad, Hiltz, & Zhang, 2005).
ADVANTAGES AND LIMITATIONS
In a survey of educators, synchronous chat was reportedly useful for holding virtual office hours, team decision-making, brainstorming, community building, and dealing with technical issues" (Branon & Essex, 2001, p. 36). Identified limitations associated with synchronous discussion included; getting students online at the same time, difficulty in moderating larger scale conversatioans lack of reflection time for students, and intimidation of poor typists (p. 36).
In a survey of educators, asynchronous online discussion was reportedly useful for encouraging in-depth, more thoughtful discussion; communicating with temporally diverse students; holding ongoing discussions where archiving is required; and allowing all students to respond to a topic" (Branon & Essex, 2001, p. 36). Identified limitations associated with asynchronous discussion included; "lack of immediate feedback, students not checking in often enough, length of time necessary for discussion to mature, and students feeling a sense of isolation" (p. 36). Based on a survey of student preferences, Dede and Kremer (1999) concluded that asynchronous discussion provided "richer, more inclusive types of interchange" (p. 4), but required more time and provided less social interaction than synchronous chat.
While synchronous discussions are more difficult to implement than asynchronous discussions, "they have the advantages of providing a greater sense of presence and generating spontaneity" (Mines & Pearl, 2004, p. 34).
NEEDS OF DYNAMIC SKILLS
In case of the online chat agenda is already set, instructors could note student input on areas of progress as well as difficulty, which could be addressed separately upon the conclusion of the chat session
or as part of an asynchronous discussion Student-centered and self-regulated teaching, using online resources to facilitate information sharing in a networked form to promote learning. Learners show higher -level cognitive Processing when they demonstrate analysis, evaluation, and creation. Dynamic skills support Adaptive (transformative and reflective) learning. Adaptive learning is prescriptive, systematic, wholostic, and humane (Driscoll, 2005, p. 139). Student-instructor interaction, student-content interaction
student-student interaction, Feedback from peers and instructor to provide asynchronous, video, audio- and text rich communication platform that simultaneously connects students to the wider affordances of the Internet (Roseth, Akcaoglu, & Zellner, 2013; Teras & Teras, 2012).
MOVING TOWARD DYNAMIC TECHNOLOGY
Distance education (distance teaching and learning) is evolving at a fast pace to include static (podcasts or video casts, Web pages, and text ) and dynamic (virtual simulations, gaming, multi-user environments, and mind tools) technologies (Moller, 2008). Moller (2008) argued that static technologies were efficient at broadcasting information and helping learners build their own knowledge, while dynamic technologies served as catalysts to engage learners in a deep understanding, application, and transfer of knowledge, through representation, manipulation, and reflection on what students knew.
Technologies allow individuals to capture information in online learning environment that is supportive of experimentation, divergent thinking, exploration of multiple perspectives, complex understanding and reflection than face-to-face learning environment.
REFLECTIONS
In asynchronous and synchronous environments, instructional designers and subject matter experts should develop, test, and implement incipient and appropriate media and technology theories with instructional and learning theories to increase students’ interactions (Borup, West, & Graham, 2013; Wenger et al., 2005). The 21st century online learning environment should portray high-quality learning activities, meaningful cognitive engagement through learners’ autonomy and interaction in a complementary manner (Bernard et al., 2009), and avoid mindless activism (Anderson, 2008).
