The decisions and actions that chemistry
educators make regarding
why, what, how, and when to teach certain content or implement a specific
instructional activity are often guided, but also constrained, by
explicit or implicit “didaktik models”. These types
of models direct our attention and actions when designing curricula,
planning for instruction, or assessing the learning process. They
also give educators a professional language when talking or reflecting
about teaching and learning. When used systematically, didaktik models
support the implementation of research-based instructional practices
and are helpful in the professional development of educators. In this
essay, we describe, analyze, and discuss the nature and utility of
didaktik models in chemistry education and argue that it is critical
for chemistry educators to recognize and reflect on the types of models
that guide their work.
