Judge any task by Nation’s eight principles: Motivation, Self-efficacy (engagement); Focus, Accuracy (usefulness); Repetition, Time-on-task (quantity); Elaboration, Analysis (quality). Good techniques satisfy several at once.

Smith’s comments

  • He’d like more on working memory and cognitive load.
  • Analysis matters less for A1–A2 novices; he’d “downplay the analysis”.
  • Incidental learning through extensive reading and listening is vital. He doubts learning words for their own sake.
  • Nation cites “at least 6 or 7 encounters” for a word, and 95–98% known words for comprehension.

Apply in my context (Claude)

  • Use this as the rubric in the teacher checklist: for one observed activity, tick which of the 8 principles it hits. It’s a fast, theory-grounded observation tool.
  • For Tanga design: rewards touch Motivation only. Make sure a rewarded activity also scores on Repetition and Focus, or it’s motivating nothing useful.
