Subclaims¶

q1 i? Because discovery sequences require students to pursue blind alleys and make mistakes, a basic incompatibility exists between the self-discovery process and error minimization. → Glaser 1966

q1 · i? · theoretical · r3

A theoretical argument in the paper: discovery sequences allow blind alleys and negative instances so errors are highly probable, whereas error minimization removes error factors without manifesting them, producing less-than-challenging tasks. Adaptive teaching systems (Lewis and Pask) instead use errors to select next instruction.

"Thus, there is a basicincompatibility between this self-discoveryprocess and error minimization."
