Description

Drawn from philosophy of science (Machamer, Darden & Craver, 2000) and operationalized in science education research (Russ et al., 2008), mechanistic reasoning treats a good scientific explanation as one that answers a "how" question: it identifies lower-level entities, their properties, and the causal chain that links a cause to its effect. This is distinguished from teleological explanations (explaining a biological trait by its function or purpose, e.g., "so that the plant can survive") and circular explanations (restating the effect as its own cause). In biology especially, teleological and mechanistic reasoning compete, and learners — including young children — can be taught to recognize which type of explanation a question actually calls for.

Implications

Context

  • Most relevant in biology and other domains where causal mechanisms are the target understanding but teleological or functional framing is common and can substitute for real causal explanation
  • The explicit "how" vs. "what/why" question framing appears to be a learnable, applicable cue for eliciting mechanistic (vs. non-mechanistic) reasoning, even in young children

Target Learners

  • Elementary-age children through adults; evidence suggests the capacity to prefer mechanistic explanations, when explicitly cued, is present well before it is typically assumed

Target Learning Objectives

  • Evaluating whether a given explanation actually answers a causal "how" question, rather than only sounding plausible or familiar
  • Constructing explanations that identify entities, properties, and causal chains rather than restating or attributing purpose

description Mechanistic reasoning explains a phenomenon by identifying the interacting entities, properties, and activities — organized in space and time — that cause it, in contrast to teleological (purpose-based) or circular (restating-the-effect) explanations.
