	* Timing of feedback fading: [[immediate feedback]] (higher [[assistance]]) can be faded into [[delayed feedback]] (lower [[assistance]]).		* Timing of feedback fading: [[immediate feedback]] (higher [[assistance]]) can be faded into [[delayed feedback]] (lower [[assistance]]).
	* Retention interval fading: Short spacing between problems or tests of the same knowledge component (higher assistance) can be faded into longer spacing.

See [[Optimizing the practice schedule\|Pavlik's study]].
			* Concreteness fading: facilitating a learner's ability to induce knowledge that transfers by first presenting a concrete example and later presenting an abstract statement of this example. The abstract statement is what the learner ultimately acquires and what allows for transfer, but the initial concrete presentation prepares the learner to understand the abstract statement.

	Worked-out steps in a [[worked examples]] are gradually turned into standard problem solving ~~steps~~ by removing the worked-out elements in the steps (the "answers"). ~~Thus~~, ~~students~~ must generate these steps (or answers) themselves.		Fading refers to a reduction in [[assistance]] or [[scaffolding]] over time. Different dimensions of assistance can be faded:
			* [[Example]] to problem fading: Worked-out steps in a [[worked examples]] are gradually turned into standard problem solving [[step]]s by removing the worked-out elements in the steps (the "answers"). As the [[assistance]] of giving the steps is faded, the steps (the answers) are withheld and the student must generate these steps (or answers) themselves. See [[Does learning from worked-out examples improve tutored problem solving? \| Renkl et al. study]].
			* Study to test fading: Study trials, which present facts ([Chinese symbol] means [English word]), can be faded to test trials, which provide a [[cue]] and require students to generate a response ([Chinese symbol] means ?).
			* Timing of feedback fading: [[immediate feedback]] (higher [[assistance]]) can be faded into [[delayed feedback]] (lower [[assistance]]).
			* Retention interval fading: Short spacing between problems or tests of the same knowledge component (higher assistance) can be faded into longer spacing. See [[Optimizing the practice schedule\|Pavlik's study]].
