    Neuro-linguistic programming, learning andeducation

    The origins of Neuro-Linguistic Programming

    Neuro-Linguistic Programming was developed by Richard Bandler and John

    Grinder in the early 19 !"s# Bandler was studying at the $niversity o% &anta

    'ru() where he met John Grinder) an assistant pro%essor o% linguistics *Bostic

    &t#'lair + Grinder ,!!1 pp 1 ,-./# 0hey began to pursue a curiosity about

    wor2 o% 3rit( Perls) the %ounder o% Gestalt therapy) and 4irginia &atir) the

    %amily therapist) resulted in a two volumes titled The Structure of Magic*Bandler + Grinder 19 5b6 Grinder + Bandler 19 7/) which describe language

    patterns that the authors identi%ied as characteristic o% e cellent therapists#

    0he development o% NLP was in%luenced in particular by conversations with

    Gregory Bateson) who was Bandler and Grinder"s neighbour in &anta 'ru( in

    the 19 !"s *Bostic &t#'lair + Grinder ,!!1p#118/# Bateson) an nglish

    epistemologist who made important contributions to many %ields) including

    anthropology and %amily therapy *Bateson ,!!!/) contributed a %oreword to

    the %irst volume o% The Structure of Magic and introduced Bandler and Grinder

    to :ilton ric2son) the hypnotherapist *Bostic &t#'lair + Grinder ,!!1pp# 1 5-

    Howard gardner, multiple intelligences and

    educationHoward Gardner's work around multiple intelligences has had a profound impact on thinking

    and practice in education - especially in the United States. Here we explore the theory of multiple

    intelligences why it has found a ready audience amongst educationalists and some of the issues

    around its conceptuali!ation and reali!ation.

    I want my children to understand the world, but

    not just because the world is fascinating and the human mind is curious. I want

    them to understand it so that they will be positioned to make it a better place.Knowledge is not the same as morality, but we need to understand if we are to

    avoid past mistakes and move in productive directions. n important part of that

    understanding is knowing who we are and what we can do... !ltimately, we must

    synthesi"e our understandings for ourselves. The performance of understanding

    that try matters are the ones we carry out as human beings in an imperfect world

    which we can affect for good or for ill. * oward Gardner 1999E 18!-181/

    &ince the publication o% their original paper in 1988) 3elder has made two

    changes to the model#

    believe that this continuum provides insight %or e ploratory testers and so will

    treat the model as i% it still contained this continuum %or our purposes# 0he second

    change 3elder made to the model was a word change %or the 4isual 4erbal
