Learning management systems traditionally provide structures to guide online learners to achieve their learning goals. Web 2.0 technology empowers learners to create, share, and organize their personal learning environments in open network environments; and allows learners to engage in social networking and collaborating activities. Advanced networking mechanisms, UGC, flat-structured architectures, RSS, and social tagging, permit online learners to define their own learning structures. This article reports an online course built within multiple Web 2.0 technologies designed to empower learners to construct their own personal learning environments within open network learning environments. Lessons learned, examples, and critical issues are discussed. This paper concludes that effective instructions should prepare "online" learners to become "network" or "open network" learners.
