There is no education system in the world - none at all - that's better than its average teacher.

As intelligent and responsible filmmakers, working in a free society, we have a duty to ensure that our chosen medium is a force for good. Especially in this ever-more complex and difficult world.

The most important thing I think teachers can do for young people is to make them inquiring, is to ensure that they know how to gather information, that they check information and they take their information from a multiplicity of sources.

A vital step for the technology sector is to signpost legitimate search options far more clearly and to delete links to sites that promote illegally sourced content.

There's always a miasma of misinformation emerging from the higher education sector as to which are the "best" courses to take. My advice would always be to ignore the perceived wisdom and look for the most reliable evidence on the ground.

Without any doubt at all, teacher quality is the fundamental differentiator. Not just, incidentally, of education, but I would argue, probably the biggest single differentiator of success for the nations of the 21st Century.

A country that fails to value its teachers, fails to value its future.
