'Synergy' originates from the Greek 'to work together'. The attainment of output, when 2 factors work together, that is greater or better than the sum of their products when they work separately.
In my teaching context I the 'educator' and 'pedagogy' produce 'student understanding / experience'. If not then teachers become redundant and students may as well guzzle their favourite poison and read books in the library! (Don't know about the library but fave poison - YES!)
Ps - My fave poison is freshly ground Arabica coffee with cream. They say coffee is the 'wine of the Sufi's!'...and RED BULL! : )
