The Lesson Planning Problem — Why Teachers Deserve a Better Solution

This article explores the hidden workload of lesson planning, why it contributes to teacher burnout, and how better planning systems plus tools like Studiely can reduce preparation pressure and support student revision more effectively.
Lesson planning does not appear on a school timetable. There is no period on Thursday afternoon marked "preparation" and no cover lesson arranged when it runs three hours longer than expected. It happens in the margins: early mornings before students arrive, evenings after marking is finished, and the Sunday afternoons that were supposed to be rest but rarely are. Teachers absorb this cost as a matter of routine, and the system has grown accustomed to not counting it.
The public conversation about teacher workload tends to focus on marking piles and administrative demands. Those burdens are real. But planning sits alongside them with its own particular weight — and the specific difficulty with planning is that it never quite reaches a natural stopping point. There is always another activity that could be differentiated, another example that could be clearer, another sequence that could flow better.
What lesson planning actually involves
A lesson is not a topic and a list of activities. Before a teacher stands in front of a class, they have typically worked through the learning objective, the prior knowledge to build from, the differentiation required for students who need extension and those who need additional support, the formative assessment moments, the sequencing of examples, the timing of each section, and the transitions between activities. That cognitive work has to happen for every lesson, across every year group, running in parallel with marking, parent communication, departmental responsibilities and the daily unpredictability of a working classroom.
The preparation burden varies by subject and context, but survey data from across the UK, Australia and Canada consistently shows secondary school teachers spending between six and ten hours per week on preparation outside their timetabled hours. In some departments and year groups, the figure is higher. Most of that time is unpaid, unprotected and counts as part of the implicit contract of doing the job properly.
The Cost That Does Not Show Up in The Data
The time itself is measurable. What is harder to quantify is what that time costs in adjacent areas. A teacher who spends Sunday evening completing next week's lessons arrives at Monday with less capacity to rest, reflect, respond to individual student needs or pursue professional development. When planning consumes the available margins, everything else compresses into what is left over.
This has consequences for the classroom too. Teachers who are carrying persistent planning overhead into their teaching hours have less cognitive bandwidth for the responsive, flexible engagement that good lessons require — the moment when a student asks an unexpected question that opens a better explanation, the point where a class is clearly not following and the sequence needs to shift, the instinct to slow down or accelerate based on what a room is actually doing. Those moments of adaptive teaching are harder to access when preparation has already consumed the week's reserves.
Teacher retention data makes a related point. In the UK, Australia and Canada, early-career attrition surveys consistently identify workload as a primary driver of teachers leaving within the first five years. Planning workload is specifically cited in many of those accounts. That is not an individual failing. It is a structural problem that individual effort cannot sustainably solve.
What a Real Solution Needs to Do Differently
Reducing the lesson planning burden meaningfully is not the same as making the current process incrementally faster. A template library speeds up one part of the problem. A bank of pre-made activities removes another step. These things help at the margins, but they do not address the underlying cognitive load — the part that requires deciding what a particular lesson needs, how to structure it for a particular class, and how to align it to the course without doing that work from scratch.
A genuinely useful planning tool would handle the structural and architectural work that currently falls entirely on the teacher: the sequencing logic, the differentiation scaffolding, the alignment to curriculum requirements. It would leave the teacher's expertise where it belongs — in the creative, relational, pedagogically informed decisions that require a human professional — rather than consuming it on mechanics that can be systematised.
That is the problem Make My Lesson is being built around. Not a faster version of what already exists, but a different model for how the preparation work gets done. Something is coming that addresses this more directly. Teachers who want to follow the development can keep track of Make My Lesson.
In the Meantime — one Useful Recommendation for Your Students
One action that takes under a minute and gives immediate value to students: share Studiely with your class. Students who open Studiely after a lesson can generate curriculum-specific revision notes, move into flashcard practice and test their understanding — without having to build their own revision materials from scratch. That is the student-facing version of the same problem. Teachers deserve better preparation tools. Students deserve better revision tools. One of those things is already available.
The teachers who manage their planning load most sustainably are rarely those with lighter timetables. They are usually those who have found a way to separate the decisions that require genuine professional judgement from the structural work that does not. That distinction — between the craft of teaching and the administrative weight that surrounds it — is the problem worth addressing properly. A solution that handles the scaffolding without removing the teacher from the creative and relational centre of the work gives back time without compromising what made the preparation valuable in the first place.
