If you teach it, you better understand it - so of course it is every teachers responsibility - regardless of whatever other title they are using - specialist, principal, administrator standards need to be understood. Teachers and administrators have clearly stated expectations and standards which easily align with a wide variety of tasks within curriculum. The NETS are clear and easy to understand, adapt, and work with. Like other guidelines - Gardener's, Taylor's etc., it is impossible to address everything all of the time, but in a spiral curriculum it can be done over time.
NETs address creativity, information gathering and communication. What we need from all learners - an ability to know and understand - - take the thinking to a higher level and of course the ability to communicate their creation - through a variety of programs and media.
Having said that - people's confidence and capabilities vary, so minimum standards being set make sense. At ISB minimum skills for use of Panthernet have been stated in order to facilitate long distance learning when necessary. Incoming educators are often overwhelmed so a succinct document with expectations is valuable.
Leadership comes not only from administrators, but from colleagues and students. NETS outline and reflect possibilites. Learning is always the focus and technology a tool.
