Similarly, inadequate hardware and software, slow internet connections, learners’ procrastination, lack of technical expertise among the instructors, insufficient orientation for learners, and a lack of release time for instructors to develop and design their online courses have been cited as barriers to faculty participation in developing and teaching online courses (Nkonge & Gueldenzoph, 2006). The researchers recommended training and support for instructors. Supporting faculty becomes significant because of the number of faculty who begin the online teaching experience with little knowledge of the process of designing, developing, and instructing an online course (Cuellar, 2002).

Both novice faculty, who may have been reluctant to participate, and expert faculty play a significant role in guiding the types of support, assistance, and training provided by institutions of higher education. Rockwell et al., (1999) evaluated the types of education, assistance, and support that faculty felt were needed to be successful in online teaching and learning. Faculty responded with the assertions that assistance and support for developing instructional materials, developing interaction, and for applying certain technologies were critical to their success in online environments. Faculty regarded teaching online as more difficult than teaching traditional courses (Gerlich, 2005) as well as complain that online delivery were more labor intensive because of the amount of time required to grade papers and respond to questions (Lao, & Gonzales, 2005; Wegmann, & McCauley, 2008; Sellani & Harrington, 2002). In other studies, faculty felt that additional instructional and technical support were needed because faculty were genuinely concerned about the quality of their online courses and the amount of technical assistance and training available to them at their institutions (Allen & Seaman, 2008; Keengwe, Kidd, & Kyei-Blankson, 2009).

Surveys conducted by Brogden and Couros (2002), Grosse, (2004), and Lorenzetti, (2004) suggest that the time and effort demands to develop online courses and to learn new technologies are also causes for faculty member’s frustrations. Additionally, some faculty members may resist online teaching because they are concerned that those courses may require more time for advanced planning (Matsom, 2006). Further, faculty members may be hesitant about this shift due to the fact that they may lose autonomy and control of the curriculum, lack of technical training and support, and lack of release time for planning. Generally, understanding the differences between traditional face-to-face learning environment and online learning environment, and the process of being able to shift from one modality to the other, will give faculty members the ability to design better online courses and focus more on course delivery (Conrad, 2004; Harlow, 2007; Marfoglio, 2006, Sugar, Martindale, & Crawley, 2007). Faculty members may also need to rethink (a) the nature of the content to be taught (b) their role as faculty members and (c) the needs and requirements of the students (Ben-Jacob, Levin & Ben-Jacob, 2000; Lee & Busch, 2005; Jones, Kollof, & Kolloff, 2008).

Figure 1: The Networked Teacher (Couros, 2008)

ouros (2008) developed a model of the networked teacher that represents an educator's professional personal learning environment (PLE). A teacher is better equipped to facilitate networked learning if he or she has experienced the construction of such a model first hand. The significant connections in Couros' view of the network include colleagues, popular media, print and digital resources, the local community, blogs, wikis, video conferencing, chat/IRC, social networking services, online communities, social bookmarking, digital photo sharing, and content development communities (Couros, 2008).

Networked teacher model

In a traditional classroom setting, the teacher has primary control over the content. He or she selects or designs the curriculum. Networked learning gives students the ability and the control to connect with subject matter experts in virtually any field.

Figure 2: The Networked Student

The networked student follows a constructivist approach to learning. He or she constructs knowledge based on experiences and social interactions (Jonassen et al., 2003). Constructivism encourages "greater participation by students in their appropriation of scholarly knowledge" (Larochelle et al., 1998).

Technology supports this appropriation as a collection of tools that promote knowledge construction, an information vehicle for exploring knowledge, an active learning tool, a social medium to promote conversing, and an intellectual partner to facilitate reflection (Jonassen et al., 2003)

Developing a model of the networked student The Networked Student Model adapts Couros' vision for teacher professional development in a format that is applicable to the K-12 student. It includes four primary categories, each with many components evident in the networked teacher version (Figure 2).

That connection expands to include access to resources and creative artifacts. Computers and mobile devices continue to broaden access to all types of information and learning sources. As quickly as content becomes available, web applications are released to assist in the management of that content

The networked student constructs a personal learning environment one node at a time. Once these connections are formed, they must be revisited and built upon to facilitate further learning. The personal learning environment lives beyond time spent in a classroom

With so much information to manage, it is increasingly difficult to stay abreast of changes in a given field, much less track implications arising from related fields. Really Simple Syndication (RSS) allows learners to subscribe to changing content and makes tracking changes easier.

Ultimately, meaningful learning occurs with knowledge construction, not reproduction; conversation, not reception; articulation, not repetition; collaboration, not competition; and reflection, not prescription (Jonassen et al., 2003).

Construction of a personal learning environment does not necessarily facilitate comprehension or deep understanding. Learning potential exists in what the student does with the compilation of content and how it is synthesised. The networked student model is one of inquiry, or the process of "exploring problems, asking questions, making discoveries, achieving new understanding and fulfilling personal curiosity" (National Science Foundation, as quoted by Chang & Wang, 2009, p. 169).

Principles of connectivism equate to fundamentals of learning in a networked world. The design of the teacher-facilitated, student-created personal learning environment in this study adheres to constructivist and connectivist principles with the goal of developing a networked student who will take more responsibility for his or her learning while navigating an increasingly complex content base.

Nine out of 15 students indicated that time management was the most difficult aspect of the course. Yet, of the fifteen students participating in the project, thirteen were able to manage weekly assignments per the schedule. Two students fell behind and expressed frustration at the amount of work required to catch up. Teacher intervention was required to facilitate their successful completion of the course. They were given a daily list of tasks designed to scaffold the time management aspects of the project. Time management issues were less associated with construction of the personal learning environment and more concerned with the blended format of the delivery. It was an adjustment for students to manage work outside of class even though they enjoyed the freedom of attending a formal class meeting only 3 out of 5 days a week.

Achieving the delicate balance between teacher control and student autonomy is an ongoing challenge when facilitating student use of new technologies for self-regulated learning (McLoughlin & Lee, 2010). Motivation, self direction, and technical aptitude are key considerations for implementing a networked student design. The students constructing personal learning environments in this test case were successful in the contemporary issues course.

spite of the challenges highlighted above, the Networked Student Model offers a design and framework through which teachers can explore a student-centered, 21st century approach to learning. It further provides a foundation for constructing a personal learning environment with potential to expand as new learning avenues emerge. The student is challenged to synthesise diverse and extensive digital materials, connect to others interacting in respectful and meaningful ways, self-regulate an active approach to learning, and develop an option for life long learning that applies to virtually any curricular area. Once a student has learned how to construct a personal learning environment, he or she is left with a model of learning that extends beyond the classroom walls, one in which the learner assumes full control. Regardless of teacher control, the students' success will depend on how well they have been prepared in the processes that support learning in an ever changing, increasingly networked world.
