Key takeaways
- Alternation is designed in blocks: concentrated theory time and concentrated practice time.
- Block scheduling reduces fragmentation; scattered singles serve neither theory nor practice.
- A dedicated workplace day beats spreading placement thinly across the week.
- Name each week's pattern before placement, so every group knows which week type it is living.
Design the alternation in blocks
The unit of design is the block, not the lesson: a concentrated run of classroom time, a concentrated run of shop time, a dedicated workplace day where the programme includes one. The sourced principle backs concentration on the practical side especially, where setup and safety overheads punish fragmentation.
The alternation then has a shape per group: which days belong to which block, and how the pattern repeats or varies across weeks. Writing that shape down is what makes the rest of this guide checkable.
Sketching the mixed week
Per group, before placement.
- List the group's theory hours, practical hours, and workplace days for the period.
- Concentrate the practical hours into blocks at their space's minimum consecutive length.
- Keep academic days coherent rather than interleaving singles between shop sessions.
- Dedicate the workplace day where the programme has one.
- Stagger patterns across groups so shared spaces stay evenly loaded.
- Name each week's pattern and publish which weeks follow which.
How to do this in Smootables: recurring and custom weeks
Timetable structure
Same pattern every week, or a different week each time?
Recurring
The same timetable repeats every week.
Custom
Week by week; the timetable can differ each week.
Holiday weeks
Extra weeks off (e.g. autumn break) that block scheduling within teaching periods.
Each period's timetable structure is one of two shapes: Recurring, where the same pattern repeats every week, or Custom, where the timetable can differ week by week. A steady alternation that fits inside one repeating week runs as Recurring; a pattern that genuinely changes across weeks (theory-heavy weeks, then practice-heavy weeks) runs as Custom, with each week's lessons planned for that week.
Holiday weeks inside a teaching period are entered so nothing schedules into them, which keeps a multi-week pattern honest about how many real repetitions it gets. The alternation design itself (which weeks follow which pattern) stays a planning decision that Custom weeks then express.
Checking the pattern holds
Three checks before the mixed week is accepted: the practical blocks meet their minimum consecutive hours, the shared spaces survive every week of the pattern (not just the average week), and each group's theory subjects still receive their required hours across the full cycle.
The space side of that middle check is workshop and lab scheduling; the placement-day side is work-based learning.
Questions planners ask about mixed weeks
Why do scattered practical singles fail?
Fragmentation costs both sides: practical sessions lose their setup-to-learning ratio, and theory subjects lose continuity between their scattered remnants. Block scheduling exists precisely because longer concentrated sessions suit deeper practical learning.
Should every group alternate on the same rhythm?
No, and shared spaces usually forbid it: if every cohort ran its workshop week simultaneously, the stations could not cover them. Stagger the patterns so the specialist spaces stay loaded evenly across the cycle.
What does a week pattern need before placement starts?
A name and a definition per group: which days are theory, which are practice or workplace, and which weeks follow which pattern. Placement against unnamed patterns produces grids nobody can check.
