For learning, what analogies can be built in terms of "tree"?

Four seasons, trees-with-leaf, and trees-without-leaf

1. a tree experiences the cycle of dropping leafs in Fall and Winter, and grows new leafs in Spring.
2. a schema-tree has both the abstracted structure, and the case-application. The abstracted structure tree is like the tree-without-leaf; the case-application tree is like the tree-with-leafs. Each time of applying is like the tree grows new leafs. In Schema Theory, accretion is about this process of using the schema in a new interpretive context

Grow bigger and bigger

1. year after year, the tree becomes bigger.
2. time after time, the the abstracted structure might become bigger if new features are added to the abstracted structure tree. In Schema Theory, attuning of schema is about this process of modifying the structure tree to make it more adapt to the new interpretive context.

Grow a new tree

1. a new tree might grow from a seed, or from transplanting from other trees.
2. for a schema tree, the new tree might grow from induction, or from reason-with-analogy.

Link/weave a few trees together

1. in a garden, a set of trees ‘work together’ to create the nice garden.
2. for schema-tree, a few schema-trees might ‘work together’ to function. A few theories and models describe this process:
1. the reconstructing of schema in Schema Theory
2. in Gagne’s outcome of learning, the hierarchy structure of building intellectual skills: from distinguishable stimuli, to concrete concept, to defined concept, to rule, and to higher-order rule.
