PIVOT decomposes teacher guidance into two complementary mechanisms: trajectory-level intervention (inserting teacher corrections into student trajectories) and token-level supervision (providing dense target signals for the correction segments).

UnverifiedOn-policy distillation requires the student to first generate its own prefix trajectory, after which the teacher provides guidance at the states the student actually reaches, so the state distributions are aligned, and it is usually more stable on long-horizon tasks where errors tend to accumulate.73% similarUnverifiedThe paper concludes formally with the analogy of a wise teacher's intervention, where the teacher can advance a learner to the next level when they stagnate at a plateau71% similarUnverifiedIn PIVOT, supervision acts only on the inserted teacher correction segments, while the original student tokens are still driven by the RLVR reward, and the two types of losses are optimized jointly.71% similarUnverifiedEducational scaffolding refers to a teacher providing temporary hints, demonstrations, or step-by-step guidance when a learner still struggles to complete a task independently, and gradually withdrawing them as ability grows; common forms include task decomposition, guiding questions, checkpoints at key nodes, and imitable examples.70% similarUnverifiedThe paper categorizes existing OPSD approaches into two types: one where the teacher is fixed throughout training and has access to the full reference; the other where the teacher is unchanged within each response but adaptively varies across responses in the degree of exposure to partial reference.68% similar
