Document Summary
Conservation is established, but more complex thinking features are still developing. Reversible mental actions applied to real, concrete objects. Seriation : ability to order stimuli along a quantitative dimension. Example: lining straws up in order of length (not just big & small categories) Transitivity : ability to logically combine relations to understand certain conclusions. Example: how three straws have different lengths, understanding how one is longer than the other. A longer than b, b longer than c, therefore a longer than c. Piaget"s conclusions at this stage have been challenged: Some children can be trained to reason earlier. Some concrete operational ability do not appear at the same time. Developmental psychologists who have elaborated on piaget"s theory. Emphasize information processing, strategies, and precise cognitive steps. Take constructivist approach active (as oppose to passive) learning. Facilitate rather than direct learning learn by doing, support the context of learning. Consider child"s existing knowledge and level of thinking.
