Direct excerpts that give a better idea of it:
"Hello Ruby will be a classic journey of discovery that teaches the readers about different people working together, how problems can be solved in small sequences and how remixing and sharing helps everyone."
"The activity book teaches kids early programming skills. It’s designed to be enjoyed by a kid alone, but can also be worked through with an adult. And best of all - the workbook is designed to be doodled, wrecked and drawn all over.
- The foundational knowledge structures, like sequences, variables, patterns, loops, lists, conditionals, operators and events. Taught through exercises of dot-to-dot, pairs, odd-one-out, all from Ruby's world.
- A sprinkle of software culture, by teaching them to abstract and modularise, work iteratively and incrementally as well as encouraging them to reuse and remix work.
- Creativity and DIY attitude. Tons of doodles, logic puzzles and even a foldable miniature laptop that allows the kid to peek inside a computer."
Even if it just inculcates problem solving techniques like breaking a problem down into its component parts and then grokking the real underlying problem rather than the symptoms, (the lack of the latter is quite prevalent these days), it will be a net gain.
