This site is an attempt to consiolidate more than 50 years of teaching experience by Keith and Allison Barrett  at schools in the UK and N.Z. so it will always be  a "work in progress" !

Material is from our bespoke student coursebooks for NCEA Physics . . .

Some is only accessible to our current students but a few pages are public and some contain links to various resources on other parts of the web which you might find useful. 

Special Greetings to our many former colleagues and students wherever you may be. . .

We are currently living in Auckland, NewZealand and, one day, we will look forward to a long and relaxing retirement . . .  Yeah right!!
