Can you think of any abstraction in each one? All of these required the people behind them to think about big, broad, and complex concepts; to break down the problem and to experiment; and to find patterns amongst the experimentations; and to eventually abstract this concrete knowledge to package it into these sterile statements that shelter us from the complexity and difficulty waded through to arrive at this law. New diseases can also be categorized and have cures, treatments, or preventions identified based on pattern recognition from other corresponding medical complications. The Search for A Student process does not know that the Student Search Pattern connects to a database and gets a list, all it knows is that it gives the black box a surname, and gets back some results. Understanding abstraction enables students to make sense of problems they encounter, helping them to not be overwhelmed in the face of something complex and to persist, compute, iterate, and ideate. and Y.W. Sweller, J. It then connects each decomposed problem to establish a complete solution. Teaching Coding in K-12 Schools pp 389399Cite as.
