So the question is "How relevant are the NETs for Teachers and Administrators to being a "Good Educator" today?"
The standards use verbs like inspire, model, learn, facilitate, encourage, evaluate, communicate, design, develop, engage, create, promote, reflect, respect, collaborate, transfer, provide, customize, personalize, adapt, pursue, participate, support, ensure, lead, establish, maintain, and contribute along with many others.
When we think of "Good Educators", aren't those the words that we think of? When we discuss "Best Practices", aren't those the words we hear? When we talk about our students and what they need to be successful in the future, aren't those the words we use? My answer is "yes" to all of those questions.
So after looking at the standards, while thinking about technology specifically and education in general, I would have to say that they are very relevant to being a "Good Educator" for administrators, teachers, and anyone involved in the education of children.
