What is the difference between massed and distributed practice in IB SEHS?

In IB SEHS, massed practice is continuous practice with little or no rest, while distributed practice includes planned rest intervals. The difference matters because rest changes how fatigue affects skill execution. With massed practice, fatigue can build quickly and reduce accuracy, which can interfere with learning quality for beginners. With distributed practice, rest supports concentration and lets performers process feedback more effectively. In exams, you score higher by linking the method to the performer and skill complexity, not just defining it. A strong answer also explains a consequence, such as reduced fatigue leading to better retention.

When should I use fixed practice instead of variable practice in IB SEHS?

Fixed practice is best when the performer is in the early learning stage and needs consistency before adaptability. In IB SEHS, you can justify fixed practice by saying it reduces cognitive demands and helps establish a stable movement pattern. It can also increase confidence because errors are easier to spot and correct when conditions stay the same. Variable practice is better later, once basic technique is reliable, because changing conditions improves transfer to real performance environments. In an exam scenario, look for clues: if the question describes a beginner, anxiety, or high error rates, fixed practice is often appropriate. If the scenario mentions decision-making, changing opponents, or unpredictable conditions, variable practice becomes the stronger choice.

How are IB SEHS practice methods tested in exams?

IB SEHS questions commonly ask you to describe a practice method, then apply it to a performer, skill, or stage of learning. Many students lose marks by listing massed, distributed, fixed, and variable practice without explaining why the method fits the situation. High-mark answers explain the mechanism (fatigue, attention, feedback, motivation, transfer) and then connect it directly to the scenario. A good habit is to write one sentence defining the method and two sentences explaining impact and application. To train this, use exam-style prompts from the SEHS Questionbank and check your structure with RevisionDojo’s AI Chat and Grading tools.
