By definition, computing unplugged develops skills in one context that must be applied to another. While this requires more of the learners than simply learning a new skill to be applied in the same context, it should develop more metacognitive awareness in learners as they apply existing learning to a new context and talk about the transfer of skills. (Caldwell & Smith, 2017)
Introducing these concepts without the context of computing makes them more abstract, not less. (Humble, 2018)
As with all approaches based on analogy, it is vital that the links to the concepts demonstrated are clearly made. Without this students can be left understanding the everyday version of the activity but not the computing concept itself. (Sentence, 2018)
