Description and scope

A reusable whole-task policy for complex skills (performance that integrates several kinds of knowledge and routine). It instantiates the cognitive load principle: learners work on whole, authentic learning tasks grouped into task classes from simpler to more complex; support within each class starts high and fades; supportive information (how the domain is organised, how to approach the task) is available before and around the tasks; procedural information (how to carry out routine steps) is given just in time; and part-task practice is added only for routines that must become automatic. The study configurations below are evidence about parts of this policy; no study recorded in this wiki tests the four components together, and the response-dependent policy is an untested design proposal. It is a pattern for any complex skill; a particular clinical, technical or professional programme built with it is a design instance.

Inputs: establish the design brief

Field Record or elicit
Learner and starting observation Task-specific experience for each task class; an attempt at a simple whole task with reasoning, errors, help needed and time; which routines are already fluent. Preserve unknowns; "novice" is per task class.
Context and activities Setting, time available, whether real or simulated tasks are possible, which supports (examples, completion tasks, coaching, job aids) can be supplied and faded, and who judges performance.
Learner-valued goal Ask what performance the learner wants and why. Record divergence from the designer's objective and negotiate task content rather than assume agreement.
Designer objective The whole-task performance intended, its knowledge type (usually complex-skill), the range of situations it must transfer to, and which routines must be automatic versus looked up.
Outcome A representative whole task scored by an agreed rubric; immediate, delayed and near/far-transfer horizons as separate outcomes; any safety outcome. Learning-phase effort or efficiency is a separate measure.

A request to "use 4C/ID" or to "teach the skill" does not supply these inputs. Ask for them before fixing the number of task classes, a fading schedule or a part-task dose.

Sequence and conditional policy

  1. Analyse the whole task. Identify the integrated performance, its non-routine (reasoning) and routine (procedural) parts, and the dimensions that make a version simpler or more complex. These are design judgements; record their basis.
  2. Elicit on a simple whole task. Before instruction, ask for an attempt at the simplest representative version, with reasoning and every help given. This places the learner in a task class; it is not a measure of a latent schema.
  3. Work through a task class with fading support. Begin with high support (worked or modelled tasks, then completion tasks) and reduce it across varied tasks of the class; give supportive information before or alongside, and procedural information at the step where it is needed, then withdraw it.
  4. Add part-task practice selectively. Only for a routine that whole-task practice does not make fluent enough and whose slowness is plausibly blocking whole-task performance.
  5. Reobserve before moving on. Use an unsupported, varied task of the current class under the agreed rubric. Move to a more complex class, stay, or adjust support provisionally; recheck at the stated delay.
Observation Discriminating probe Proposed action, with its uncertainty
Cannot start even the simplest whole task Present the same task with mutually referring information integrated and one interacting element pre-taught; ask for the first decision and why. If performance returns with integration or pre-teaching, keep the whole task and add that support or a simpler version. If not, consider brief isolated-element practice before the whole task. Neither branch is validated.
Succeeds with full examples or completion tasks, fails without Give one unsupported varied task of the same class; ask which relation licenses each step. Stay in the class and fade more gradually (removing the last worked steps first is one tested option). One failure does not show that support must stay.
Correct whole-task reasoning but slow or error-prone on one routine Time the routine on its own and inside the whole task; vary whether a job aid is available. Add short part-task practice or a just-in-time aid for that routine, provisionally; drill is not warranted for routines the objective allows to be looked up.
Fluent, unsupported success across varied tasks of the class Present a task from the next class and a changed condition within the current one. Move to the more complex class with high support again, and remove support the learner no longer needs, since redundant guidance may cost the learner. The exact point is not established.
Low participation or reliance on hints regardless of difficulty Ask about purpose, stakes and barriers; compare a task closer to the learner's valued goal. Negotiate task content or conditions; hint use and effort alone do not establish the learner's state.

Choosing configurations from evidence

  • Whole tasks as the organising unit. Whole-task practice for transfer of complex skills [+W] rests on one design argument, not an experiment: it holds that the load-reducing methods suited to retention (low variability, full guidance) hinder transfer, and proposes high variability and limited guidance, with intrinsic load lowered early for novices. Use it as the pattern's rationale, not as evidence of an effect; judge-checked against its abstract.
  • Isolating interacting elements first. For novices on high-element-interactivity tasks, isolated parts before the integrated whole [+M] improved performance in one experiment (sample, outcome and horizon not reported on the claim page; not yet checked against its sources). It supports pre-teaching or part-task practice as an entry step; it does not test part-task practice for automating routines inside a whole-task sequence, which is 4C/ID's use.
  • Fading within a task class. Fading from complete to incomplete examples to problems [+M] favoured near transfer over static example–problem arrangements in three experiments (20 ninth graders; 54 and 45 college students), and removing the last steps first was more favourable. It does not establish a fading rate or far transfer; not settled against its sources.
  • Adjusting support to the response. Contingent scaffolding [+M]: one-to-one long-division tutoring for fourth and fifth graders (N=8 per condition) found fully contingent support ahead of fixed, moderate or no support at immediate and one-month tests; contingent tutoring matched non-interactive tutoring immediately but improved transfer in a second study (11 pairs); a meta-analysis ranked scaffolding above coaching but below explicit strategy training. Small samples, mostly one-to-one; not settled against its sources.
  • Removing support as expertise grows. Worked-example guidance becomes less effective as expertise increases [~M]: two reviews, abstract only and not settled, argue that full guidance becomes redundant and should be faded toward independent problem solving. It qualifies keeping high support across task classes; it gives no threshold.

Do not combine these into a predicted effect for the whole pattern. They differ in learners (children, secondary and college students, trainees), task, comparator and outcome, and none measured delayed whole-task performance in a workplace.

Fitting the design to a situation

Ask for four facts when the brief omits them: the simplest whole task a learner can attempt, which routines must become automatic and which may be looked up, whether real or simulated whole tasks are possible, and the transfer horizon that will judge the programme.

If the brief says… Then change… Basis
The goal is transfer of a complex skill to varied situations Organise the programme around whole tasks in classes from simple to complex, with varied tasks within each class Whole-task practice improves transfer (design argument) [+W]; Varied tasks of one type enable transfer [+W]
Learners are complete novices and the task has many interacting elements Start with brief practice on isolated elements, then move to the whole task Part-task practice reduces load for novices [+M]
Within a task class Fade support from worked examples to completion tasks to independent tasks Fading support promotes transfer of responsibility [+M]
Learners in one class differ in prior knowledge Give lower-prior-knowledge learners full worked examples longer, and move higher-prior-knowledge learners to completion tasks sooner Lower-prior-knowledge learners do better with full worked examples [~M]
Learners arrive experienced in the skill Start in a later task class or with less support; full guidance becomes redundant Worked-example guidance becomes less effective with expertise [~M]
A tutor or adaptive system can watch the attempts Adjust support to the last response: more after a failure, less after a success Contingent scaffolding improves learning [+M]
A short professional workshop judged by a knowledge test Do not expect a knowledge-test gain over a lecture; judge the design on a whole-task performance check (for example an OSCE), and power the comparison No knowledge difference between lecture and 4C/ID [~M]; 4C/ID's OSCE advantage was not significant [~M]
Learners are learning to program or troubleshoot Sequence task classes from completing to fixing to building; diagnostic reasoning appeared as tasks moved on Scaffolded task progression shifts novices toward diagnosis [+W]
One routine is slow or error-prone inside otherwise sound whole-task work Add short part-task practice or a job aid for that routine only untested proposal

Illustrative design instance and observation record

Illustration only, invented, not a tested programme. A new technician wants to fix faults on the machines in their own plant; the training lead's objective is passing a standard fault-finding assessment. Agree a representative whole task (diagnosing a simulated fault on a familiar machine), task classes from a single obvious fault to intermittent multiple faults, a reasoning-and-outcome rubric, permitted aids (the wiring diagram, not the fault table), and a one-month delayed task on a less familiar machine as the transfer outcome. Meter use, a routine, gets part-task practice only if it is slow inside the whole task.

Record: task and class → support given and removed → response and reasoning → candidate interpretations and confidence basis → distinguishing probe → chosen next task and justification → next observation at the stated horizon. Preserve the learner's stated purpose and any change in it. An agent may summarise this record, but must not invent missing inputs or assign numerical state probabilities without a calibrated model.

Elements and limits

Whole-task performance, supportive information, procedural information, just-in-time information, part-task practice, fading, scaffolding, worked examples, problem presentation and assessment. The pattern also applies guided practice, problem-based learning, competency-based learning and assessment and worked examples; the worked-examples pattern is the lesson-level policy for the support inside a task class.

This pattern is scoped to complex skills where whole-task transfer is the objective; it is excessive for single facts or one-step procedures, and its analysis and sequencing cost design time. The evidence above tests components in other configurations, not the pattern as a whole, and the conditional branches remain to be tested with learners.
