HCD.28:4.3 - Construct the connections in one complete learning route

Build from the result backwards far enough to make the route executable, then walk it forwards from the actual entry. HCD.5 selects a development mechanism for the missing action; HCD.6 supplies the whole task, subject criterion, permitted help and meaningful variation. Use HCD.6.1 when a necessary distinction is not yet discernible.

For each connection, state the produced result and what the next action can do with it:

• A worked contrast must expose the condition that changes the model, so the next task can ask the learner to select without that answer-bearing cue.
• A first attempt must leave an interpretable judgement or performance, so feedback can address a particular error.
• Feedback must arrive in time and identify a usable change, so the learner can make and inspect a correction.
• A subsequent task must preserve or change the condition relevant to the intended inference, so success is not silently reclassified as transfer.
• A material or practice revision must reach the relevant provider and learner before their next use.

The 4C/ID account supplies a useful distinction among whole learning tasks, support for non-routine reasoning, information during routine action and additional part-task practice where needed. Use that distinction to avoid replacing the whole task with unrelated drills. It is not a requirement to add every component to every small product.

Choose which contributions can be simultaneous and which require an earlier result. Unit support can remain available during diagnosis; an independent model choice must precede help that names the model if that independence is the intended observation. A qualified existing task or provider result can close a dependency immediately.

Use HCD.20 when interaction with other learners is a serious option and HCD.22 when a shared task must be constructed. A supported individual route is a complete product option. A group is useful only through the learning actions and contributions it makes possible.

When the route needs interaction, obtain the selected contribution rather than add every group activity. HCD.21 establishes compatible membership and contact. HCD.23 develops explanatory exchange; HCD.24 develops judgement and revision through peer review; HCD.25 connects project comparisons to personal use. HCD.26 supports a group whose actual work departs from its intention, and HCD.27 connects personal preparation, shared episodes and recovery. Each result returns its real preparation, help and timing conditions to the whole-product comparison.
