Compare what you do with help and what you do alone
Find the level you reach with good support and the level you reach without it, then work in the gap between them.
なぜ効果があるのか
Lectica’s summary of Fischer’s theory separates the optimal level, the highest a person performs with appropriate support, from the functional level, what they perform unaided. The gap is information: on this page’s inference, a person who can do something only with a prompt may have a skill still being assembled. Lectica says learners can generally construct a new skill with appropriate support faster than they can on their own. This page takes the next step as its own application: working at the supported level and then reducing help may move unaided performance toward it, which Lectica does not describe.
やり方
- Choose a task you can do with a good prompt, example, or partner.
- Do it once with that support, and note exactly what the support supplied.
- Do it again with less support, starting from your own plan.
- Keep reducing the support until the unaided version is no longer a stretch.
エビデンス
Kitchener, Lynch, Fischer and Wood (1993) is a study whose title names the effect of contextual support and practice on developmental stage. I confirmed the citation record but could not read the findings, so this page states no effect size from it. The optimal and functional distinction itself comes from Lectica’s summary of Fischer’s theory. The fading of support in the how-to is this page’s application; Lectica describes support helping learners build skills faster, not its removal. (mechanistic)
The distinction describes performance under two conditions, not a fixed ability. Help can also hide what a person cannot yet do alone, so unaided performance needs checking regularly.

よくある間違い
Reading the drop in unaided performance as proof the skill was never there, and stopping practice instead of reducing the support one step at a time.

Dynamic Skill Theory: Development Built Context by Context の実践法をもっと見る
- Name the context a skill belongs to
Write down the situation in which a skill works, because the skill is tied to that situation.
- Practise a skill in the real situations you will meet
Practise a skill in the kinds of situations you will actually meet, not only the one where you first learned it.
- Let different skills sit at different levels at once
Accept that one part of you can be advanced while another is still forming, and work on each one separately.
- Expect a skill to slip under stress and plan for it
Expect that a skill may drop under pressure, and plan the support for that moment.
- Build the emotional and meaning side of a skill, not only the action
Pay attention to what you feel and what the skill means to you, because both are part of the skill you are building.
- Ask what support the situation is giving you right now
Before judging your performance, name the people, tools, and cues the situation is supplying.
