Popular science books are not meant to be purely educational, it's a type of books designed for entertainment where the learning is just a byproduct. This article make so many generalizations and assumptions that I can hardly take it seriously. Lectures do work if they are made to reinforce the textbook materials, though by itself it simply isn't enough and you need to have other forms of learning - active ones where the students solve the puzzles, work in group on problem solving, building toy projects, etc.
