Tables, charts, quick reference cards, booklets and handbooks; are the most versatile tools of learning and putting the learning into applications. These should not have a lot of language or flowing text. These are – to the point, easy to remember, graphical, colorful (memory aid). Just like a circuit diagram, flow chart or ladder logic [...]
