Every teacher wants their students to succeed. All teachers put in hours of effort to build the competence and confidence of their students. Yet across most schools in most subjects, there is a subtle but pervasive problem: teachers giving students tasks that directly contradict the conditions under which students will ultimately be assessed. Perhaps the most common way I see this manifested is when teachers set an exam question for homework but do not set a time limit. Students are encouraged to produce their best answer, without the contraints of timed conditions. On the surface, such a task may seem not only harmless but supportive: but what are the risks involved?
Teachers rarely encourage harmful practice out of sheer carelessness: quite the opposite. Such practice arises from good intentions. Teachers often want their students to slow down, to think carefully and to produce their best work. Removing time pressure feels like a way of fostering both their learning and their skills. Teachers are also conscious that timed tasks can cause stress and many, understandably, fear overwhelming their students; ironically, it is most often the already-anxious student that is most damaged by the practice of no time-limits, since the temptation to spend an excessive amount of time on a task in order to produce a perfect answer may be overwhelming for them. Likewise, such students are usually the most deeply affected by the looming prospect of time pressure in an exam. Thus, in their desire to reduce pressure on their students, teachers may unwittingly create more pain for the most anxious of students in both the short-term and the long-term.
Another reason why teachers may set a task without time parameters is that when students are given more time, they often produce more complete work. Completed work gives the teacher more to comment on and the student more to reflect on. Students are more likely to manage to write something at length if they are not under strict exam conditions and thus teachers have more to work with when it comes to marking and feedback. Again, however, we are faced with a painful irony as a result: not only are students practising the wrong skills, their teachers’ time is being wasted as it is being spent giving detailed feedback on irrelevant skills. To be frank, everybody loses.
What is thus most surprising about some teachers’ reluctance to impose time-limits on their students is that they fail to see how setting time-limits is a win-win situation for everyone. Not only will the student benefit from the fact that they are practising precisely what they will need to do in the examination, that student will benefit in the short-term from a homework task that is time-bound and manageable. Far too often, students are set open-ended tasks which can expand to fill the time they have available: for anxious and/or high-achieving students, this can be almost infinite. Likewise, the time that teachers have to spend on marking and feedback is minimal and needs to be tightly-managed, for the sake of their own workload and to ensure that the time they do spend on that task is valuable and effective. I will never forget Professor Paul Black (50% of the brains behind the now-ubiquitous educational concept of Assessment for Learning) stating to a roomful of teachers that we were all marking too much, too often, for too long and (here’s the really devastating bit) that we were all wasting our time. That was 25 years ago. And we’re still doing it.
Outside of workload, a further risk that arises from setting students exam-style questions with no time limit is the illusion of competence. Cognitive psychology has repeatedly demonstrated that students — and indeed their teachers — can be misled by what feels effective in the moment. When a student has unlimited time on a practice essay, their cognitive load is relatively low. There is no pressure to recall information quickly, organise ideas under time constraints or make strategic trade-offs between detail and speed. As a result, tasks feel more manageable and the final product looks polished. Students and teachers might both reasonably conclude that they are exam-ready on that topic, but this belief is built on a false foundation. What are they actually ready for? In real exams, time limits force rapid decision-making. Perhaps what is most important is that students must develop an understanding that examinations do not demand perfect, polished answers: to expect this under time pressure would be grossly unreasonable. Students must learn the importance of producing a sensible, structured response that is as well-crafted as can reasonably be expected in the time allowed. This is not the same thing as what one might produce given infinite preparation and review time, for example when drafting a manuscript for publication. When exam practice is performed without time constraints, students may master individual components of the task (knowledge, technique, structure) but they will fail to integrate them at speed during the exam. Students who have never practised in timed conditions may also experience extreme panic when they first encounter them, at a time when it is too late to build that resilience.
Research tells us that learning sticks when students are forced to retrieve information under conditions that mimic the challenge they will face. Slow, open-book, or time-unlimited tasks do not recreate the retrieval demands of an examination. They allow students to look things up, pause, think in a leisurely fashion or redraft their answers. Yet again, they are practising the wrong skills, as these behaviours are impossible in an exam room. For a skill to transfer from practice to final performance, the practice must include the key features of the performance context. Practising sections of a piano piece slowly can help with accuracy, but to perform at performance tempo, you must ultimately practise at performance tempo: you must also avoid repeating mistakes in your practice, lest they be embedded. The same principle applies to writing essays, solving equations and analysing sources.
Musical practice is not the only example of a process that academic teachers could learn from. The older and more experienced I get, the more I realise what an oversight it is that academic teachers do not listen to and learn from our sporting peers. Athletes understand the training process: they understand how to break challenges down into achievable goals and what is needed in order to practise for a final performance. More and more, I talk to my students about their studies in a way that draws on the processes used by competitive sports men and women.
With many students facing their Mock examinations at around this time, the extent to which they are prepared for those is very much on everyone’s mind. Without a doubt, most teachers understand all too well that students need to be familiar with the look and feel of assessment questions, and try to produce questions which mimic the phrasing and typical format of the questions that they will face. They also know that students need to practise retrieving their knowledge without notes, prompts, or textbook guidance. Yet the thing that is most commonly overlooked with exam-matched practice are realistic time constraints. I would argue that to encourage students to practise answering these without the additional parameter of time constraints is a dangerous and counter-productive waste of everyone’s time.
