I do not believe in any way shape or form that it is the network which has performed the teaching miracles but has had a really positive effect on the teaching and learning environment at our school to which the SLT would add their seal of approval.
As for your analogy using a credit card non payment my be how you operate in your school but believe me without the smooth operations of a communications system which allows full and integrated services for everyone to use 24/7/365 then the teaching and learning in today's schools would be archaic to say the least.
A poorly prepared teacher cannot and will not survive in today's schools and the biggest let down to our students are teachers who do not plan and use the communications systems to teach the students.
The students learn through being taught but it is the tools with which they are taught with which gives them the confidence and skills to move into a bigger world away from school.
What you are saying in your way is that students would learn from teachers if there were no communication systems via chalkboards and the like or would you have the students using a wax tablet or slate?
Networks are as important to schools as they are to business and this has been proven many times over.
How many of us use the internet (Youtube) to learn from, the same goes for students, they don't need teachers in a lot of cases only for the fundamentals like reading and writing with possibly maths as the third option but for creative learning there is nothing like the internet and a communications device of sort i.e. computer, mobile phone etc.
Example: my son had never shown any leaning towards a musical instrument of any kind but 4 months ago he decided he would like to play the guitar, using his laptop and youtube he has taught himself to play and not only that he is now in 2 bands, one a rock band and another which is an Indie band. he plays Bass guitar in the rock band and lead or rythmn in the other.
Both groups now play around the clubs and pubs and are doing very well for new groups but I digress so back to the point of teachers teaching students and networks they all go hand in hand I feel.
This reply is not to inflame anyone but to put across what has happened at our school and why our SLT revere us as a much needed team and this is why the post took on that form. :D
