Representation, intuition and feedback

Represent the same problem a second way and inspect what becomes visible or easier to explain.

Choose a question

What does a matrix do, and which outputs can disappear? →Read a column as an arrow, then a matrix as an action on that arrow. Solving an equation becomes a question about reachable targets, giving collapse, eigenvectors and rotations a geometric interpretation.What becomes visible when you change representation? →An average, a spectrum and a geometric diagram each foreground a different structure. Before asking which view is intuitive, ask which comparison you need it to support.After an edit, how can you see what actually changed? →A green test, a live picture and a replayable history all count as feedback. Follow one edit and ask which consequences become visible and which still need reflection.How can you tell a correct answer from understanding? →Ask two people to explain their reasoning, then change the presentation and ask them to reconstruct the answer. Peer instruction and geometric intuition offer different ways to expose gaps.
