Children are, first and foremost, individuals and so it follows that their developmental patterns are influenced by environmental conditions. With even twins differing in their abilities and milestones, it is near impossible to predict at what rate a child will learn. Thus children enter school with a wide range of abilities — and therefore possibilities.
However, the assumption that all children can learn the basic curriculum at the same pace, in the same way and to the same extent and level- is unsupported either by research or by personal experience. If we agree that children have varied strengths (multiple intelligences) the it surely follows that teaching methods have also got to vary correspondingly and that there have got to be multiple teaching styles.
This issue addresses many of these concerns and to do that we have a wide range of articles from writers across the country which establish resoundingly that every child can indeed learn — only it requires empathy and compassion from the teacher to make it happen.
