CDLA · Module 4 — Pathway and blend architecture

Advanced: whole-task sequencing for complex skills (4C/ID)

The four-component instructional design model: learning tasks in task classes from simple to complex, supportive information, procedural information and part-task practice. How to sequence a pathway for skills that cannot be learned in pieces.

What this lesson covers

  1. 01

    They passed every module and still cannot do the job

    A project-management program teaches scheduling, then budgeting, then risk, then stakeholder communication, each with a passed module. On their first real project, graduates cannot handle a delay that affects the budget, the risk register and the client at the same time. They learned the parts. Nobody taught them to coordinate the parts, and that coordination is the job.

  2. 02

    The four components

    Learning tasks: Whole, realistic tasks from day one, grouped into task classes from simple to complex. Within each class, support fades from worked examples to independent work.

    Supportive information: The mental models and strategies for the non-routine parts: how experts think about the problem. Given before each task class.

    Procedural information: Step-by-step how-to for routine parts, given just in time, during the task. Ideal for job aids.

    Part-task practice: Extra drill only for routine parts that must become automatic, such as a system shortcut or a calculation.

    Task classes for a claims assessor

    Task class | What makes it this level | Support

    1 | Single-vehicle claim, complete documents, no injury | Worked example, then completion problem, then independent

    2 | Missing documents or a disputed amount | Same fade, new supportive information on negotiation

    3 | Multiple parties, injury, possible fraud cues | Same fade, supportive information from the CTA interviews

  4. 04

    Topic sequencing and whole-task sequencing

    Topic sequence: Module per topic; integration left to the final project. · All theory up front. · Procedures memorised in a module.

    Whole-task sequence: Every task class is a whole job, simple first. · Supportive information just before the class that needs it. · Procedures delivered as job aids during tasks.

  5. 05

    When to use 4C/ID, and when not to

    4C/ID is built for complex skills: many interacting parts, non-routine judgment, and transfer to new situations. Use it for roles like supervisors, investigators, project managers, clinicians, sales advisors on complex products. Do not use it for a single procedure or a compliance rule, where a short module and a job aid are enough. The cost is real: designing task classes requires a good task analysis and enough realistic cases. The payoff is that the first real project is not the first time learners coordinate the parts.

  6. 06

    Define three task classes

    If your program builds a complex skill, rewrite your milestones as three task classes. For each, describe what makes a case belong to that class and list two real cases. If your skill is not complex, write one sentence explaining why 4C/ID is not needed. Either answer completes your pathway map.
