This subtopic covers domain-specific pedagogical knowledge including common learning mistakes and misunderstanding. Each domain of learning and skill development has its own set of possible mistakes, misunderstandings and mitigation strategies.
Future versions of this Body of Knowledge may have sun-subtoics that point to ontologies for specific domains and stages of learning.
From the Learning Engineering Toolkit
While the Toolkit does not use this page's exact label, its most relevant discussion makes the case that teaching has to be adapted to the particular discipline being learned. It argues that metacognitive work needs to be built into instruction within every subject area, because what a learner has to keep track of differs from field to field [LET-02]. For instance, a student of history might interrogate a document's authorship and weigh how that shapes the account of events, while a physics student instead checks whether she has grasped the physical principle in play [LET-02].
Grasping how subject-matter experts talk themselves through a problem, and making that reasoning visible to novices, helps learners chunk knowledge in ways particular to the domain — organizing and grouping it as it settles into long-term memory [LET-02]. The book likewise emphasizes that learners need to build ties to the settings and practices in which the knowledge is used, to the central ideas that give it structure and meaning, and to the notations and modes of communication that practitioners in the field rely on [LET-02].
This page organizes pedagogy around the mistakes and misunderstandings that recur within a domain, an emphasis the Toolkit shares. It advises that those who build learning experiences need command not just of the content but also of where learners typically go wrong and how to help them recover [LET-09]. The book discusses the work of unlearning — guiding learners to swap out faulty, partial, or incomplete mental models for accurate ones, and using formative assessment to surface their gaps, biases, and misconceptions [LET-09]. A related problem that cuts across disciplines is the expert blind spot, where more knowledgeable people presume novices understand things that their actual performance shows they do not [LET-02].
