  • As these systems evolve, the number of inputs and outputs generally increases. Each time a new node is added to the network, the number of potential connections required scales exponentially
  • Furthermore, because there is only one standard, there is no incentive for innovation, which means that the system cannot evolve.
  • Single standards are notoriously difficult to overcome or dislodge, even when they become ludicrously inefficient, as is the case with the Western “QWERTY” keyboard layout.

  • the system has great difficulty overcoming its own internal structure and adapting to the change.
  • Complex systems of this type, that are too loosely structurally coupled, maximize their openness to innovation but do so entirely at the cost of being able to exploit those innovations when they are useful
  • a panarchy
  • The bow-tie structure manages these tensions by occupying an “edge of chaos” zone in between too much rigidity and too much flexibility, between too little diversity, and too much.
  • There is a need to capitalize on potential efficiencies in one’s current environment while at the same time remaining flexible enough to adapt if the environment changes
  • confusing the necessary cluster of evolving core elements with a “standard
  • Future networks operate on multiple standards in the core — optimal levels of infrastructure arrived at by open innovation in the periphery that makes its way into the core as adoption and usage increase.
  • widely agreed upon cultural understandings and practices.

The End of Techno-Critique: The Naked Truth about 1:1 Laptop Initiatives and Educationa... - 8 views

  •  
    This article responds to a generation of techno-criticism in education. It contains a review of the key themes of that criticism. The context of previous efforts to reform education reframes that criticism. Within that context, the question is raised about what schools need to look and be like in order to take advantage of laptop computers and other technology. In doing so, the article presents a vision for self-organizing schools.

    Prestridge identifies three professional learning activities vital for meaningful ICT teacher PD; collegial dialogue;investigation; and reflection. She chooses to investigate the role of collegial dialogue in developing learning communities and enabling pedagogical change. This is intended to inform a model for ICT professional development, using online discussion forums to facilitate discussion.

Research Summary 3: Teacher PD in ICT « hELPC! - 9 views

  •  
    That it is necessary to shift away from ICT-skills centred PD, towards reflective, pedagogically focused learning, is clear. Unless we, as teachers, can justify using ICT and make pedagogical changes to enhance student outcomes, then efforts to 'teach' ICT will be superficial. Embracing a Communities of Practice model for ICT PD incorporates the ubiquitous recommendations; that ICT PD should be collaborative; ongoing; focused on teacher needs;and facilitate critical discussion amongst colleagues.
