Draft a worked example with faded practice in ninety seconds

Draft a worked example with faded practice in ninety seconds

You know the moment. You've shown them one example, most of them nod, half of them weren't watching, and now you've released the class to independent practice and thirty seconds later four hands are up and eight more should be. The research has been clear on the fix for fifty years, and it's not "show another example." It's fade. One fully worked example, then a partially blanked version where the student names the next step, then a more blanked one, then one they do alone. Sweller wrote the papers, Rosenshine wrote the checklist, and roughly nobody in a busy staffroom writes a full faded sequence for tomorrow's third period. This prompt does the design in ninety seconds. You still bring the teaching.

The prompt

You are helping me design a WORKED-EXAMPLE SEQUENCE for a [YEAR LEVEL] [SUBJECT] class in an Australian school. The concept I am teaching is [CONCEPT]. The whole sequence should sit inside a 20 to 25 minute block of explicit teaching, before I release the class to a longer independent task.

You are working in the tradition of Sweller on cognitive load, Kirschner, Sweller and Clark on why minimally-guided instruction fails novices, and Rosenshine's Principles of Instruction, especially principles 4, 5 and 6 (present new material in small steps, provide models, guide student practice).

RETURN FOUR ITEMS, IN THIS ORDER.

1. ONE FULLY WORKED EXAMPLE.
   Show every step a student needs to see. Do not skip the "obvious" step. What is obvious to a subject teacher is the step novices trip on.
   Next to each step, write a one-line explanation of WHY that step, in language a student in this year level would actually use. This is the "self-explanation" a novice would produce if they had already mastered the concept, and it is the thing we are trying to install.

2. A PARTIALLY FADED VERSION of the same type of problem, with different numbers or context.
   Show the problem in full.
   Show the FIRST one or two steps worked out.
   Blank out the middle. Where a step should be, insert a bracketed prompt like [What do we do next? Why?] that forces the student to name the move, not just fill in a value.
   Show the final step. This anchors where the sequence is going.

3. A MORE FADED VERSION, again with different numbers or context.
   Show the problem and the first step only.
   Everything after is [Your working, one line per step, with a "why" beside each].
   End with one explicit metacognitive prompt: [Which step were you least sure of, and why?].

4. ONE INDEPENDENT-PRACTICE PROBLEM.
   Same concept, same structure, different numbers or context so it is not memorisable from the earlier three.
   Below the problem, list the two or three most likely errors a student will make on THIS specific problem, so I can walk the room with a checklist rather than a vague "how's it going".

CONSTRAINTS.
- Australian English. Metric units. Australian contexts where relevant.
- Match the reading level of [YEAR LEVEL].
- If the concept has a well-known misconception at this year level (for example, the equals sign as "the answer goes here" in early algebra, or confusing weight and mass in junior science), name it in a one-line note at the top of the sequence.
- Do NOT reuse the fully worked example's numbers in the faded versions.
- If any part of the concept is genuinely ambiguous at this year level (for example, how much rigour to apply in a Year 8 proof), STOP and ask me before writing the sequence.

What it does well

You get four calibrated versions of one idea in a single pass, and the self-explanation lines beside each step are the piece most teachers skip when writing this by hand. That's the piece the cognitive-load research says actually moves the needle. The "likely errors" list under the final problem is the small bonus that turns your walk of the room into a diagnostic pass rather than a lap.

Where it falls over

The prompt only holds together if your [CONCEPT] is procedural enough to be worked step by step. Ask it for a faded sequence on "the causes of the First Fleet" and you get a bad flowchart. And you still have to check the working on the first example. It gets Year 10 algebra right most of the time. The times it doesn't are the times a student would have been quietly taught a wrong method for a week, so read the output before you print it.

Try it like this

• For Year 7 maths: [CONCEPT] = "solving one-step equations with a negative coefficient". You get a clean sequence ready to drop onto a printed handout.
• For Year 10 chemistry: [CONCEPT] = "balancing the combustion equation for an alkane". Ask it to include state symbols in every step.
• For VCE Legal Studies: [CONCEPT] = "applying the four elements of a valid contract to a scenario". The faded versions become the scaffold for Friday's extended-response task.
• If you only have five minutes: fill in just [YEAR LEVEL], [SUBJECT] and [CONCEPT], skip the misconception line, and print the middle faded version straight onto tomorrow's slide.

Rosenshine ran the numbers on this in the seventies. He was right then. He is right now. What's changed is the ninety seconds.
