v0.13.20: @newsroom.writer: programming, taught upside down

Programming, taught upside down: what Paul Lockhart said about teaching maths applies to teaching code.

• Concepts before purpose. Why programming is usually taught upside down, and why people dislike it.
• The hook is control. A thought to something that works, in a short loop: the REPL.
• The tools that got the loop right. BASIC on the ZX Spectrum, Visual Basic, the spreadsheet, Scratch and Code Club.
• The Excel irony. Taught badly, people program in Excel anyway.
• Explorer coding starts at the right end. And coding is communication: people will read more code, not less.
• Four infographics. Upside down, the loop, the Excel irony, and coding as communication.
