Different stages of absorbing and processing information in kids

I came across this great article by Susan Wise Bauer, that helps us understand why our 12 year olds in Vanguard don't reason or process information the same way our 15 year olds do :)...why when we ask them to reason and apply it is so challenging at a younger age, when they are just getting into using logic to reason about what they are learning.  I included the entire first part of the article, and give complete credit to her and her genius with no profit to myself, other than the betterment of the world around me, and therefore a benefit to myself :)...

What is Classical Education?

by Susan Wise Bauer

Classical education depends on a three-part process of training the mind. The early years of school are spent in absorbing facts, systematically laying the foundations for advanced study. In the middle grades, students learn to think through arguments. In the high school years, they learn to express themselves. This classical pattern is called the trivium.

The first years of schooling are called the “grammar stage” — not because you spend four years doing English, but because these are the years in which the building blocks for all other learning are laid, just as grammar is the foundation for language. In the elementary school years — what we commonly think of as grades one through four — the mind is ready to absorb information. Children at this age actually find memorization fun. So during this period, education involves not self-expression and self-discovery, but rather the learning of facts. Rules of phonics and spelling, rules of grammar, poems, the vocabulary of foreign languages, the stories of history and literature, descriptions of plants and animals and the human body, the facts of mathematics — the list goes on. This information makes up the “grammar,” or the basic building blocks, for the second stage of education.

By fifth grade, a child’s mind begins to think more analytically. Middle-school students are less interested in finding out facts than in asking “Why?” The second phase of the classical education, the “Logic Stage,” is a time when the child begins to pay attention to cause and effect, to the relationships between different fields of knowledge relate, to the way facts fit together into a logical framework.

A student is ready for the Logic Stage when the capacity for abstract thought begins to mature. During these years, the student begins algebra and the study of logic, and begins to apply logic to all academic subjects. The logic of writing, for example, includes paragraph construction and learning to support a thesis; the logic of reading involves the criticism and analysis of texts, not simple absorption of information; the logic of history demands that the student find out why the War of 1812 was fought, rather than simply reading its story; the logic of science requires that the child learn the scientific method.

The final phase of a classical education, the “Rhetoric Stage,” builds on the first two. At this point, the high school student learns to write and speak with force and originality. The student of rhetoric applies the rules of logic learned in middle school to the foundational information learned in the early grades and expresses his conclusions in clear, forceful, elegant language. Students also begin to specialize in whatever branch of knowledge attracts them; these are the years for art camps, college courses, foreign travel, apprenticeships, and other forms of specialized training.

Of course, there are kids that are more logical and more ready for "rhetoric" sooner than others, but it can explain the struggle (hence, blank stares) that younger scholars experience when asked to reason and apply what they are learning.
