Built environment

Very low or no impact for low cost, based on very limited evidence.

What is it?

Changing the physical conditions or built environment, either by moving to a new school building or seeking to improve the structure, air quality, noise, light, or temperature of an existing building or classroom.

How Effective is it?

Overall, changes to the built environment of schools are unlikely to have a direct effect on learning beyond the extremes (i.e. once an adequate building standard has been achieved).

Moving to a new building could be an effective part of a whole school change that seeks to change behaviour and establish new norms (similar to introducing or changing School Uniform), but there is no evidence that new buildings or particular aspects of architecture directly improve learning. Where a new building is being used as a catalyst for change, there is some evidence supporting the impact of co-design, or involving teachers and other staff in taking responsibility for learning spaces and changing their behaviours as they adapt to new settings.

Most individual factors in the physical environment show a relationship with learning only at the extremes. If the noise levels are very high (such as under the flight path of an airport) then there can be a measurable detrimental effect on learning. Very warm (particularly above 30°C) and very humid conditions can cause a loss of concentration and drowsiness. It appears that lighting in schools is usually adequate for reading and writing.

The evidence suggests low internal air quality does have a negative impact on attainment (reducing word recognition by 15% in one study). Low air quality can occur due to the buildup of carbon dioxide in poorly ventilated classrooms.

How secure is the evidence?

The research on the impact of the built environment on learning is generally weak, and is mainly based on correlational studies or drawn as inferences from wider environmental research. There are very few rigorous experimental designs, and this makes it hard to establish causal claims about the impact of physical changes.

What are the costs?

It is very difficult to estimate the costs of changes to the built environment as they are usually part of capital spending and a single cost, rather than a recurrent part of a school budget. A new secondary school costs about £15 million for 1,500 pupils or £10,000 per pupil. However several generations of pupils are likely to use the building. Improving air quality can be done relatively cheaply with better ventilation, filtration and the use of dehumidifiers where necessary. Overall, costs are estimated as low.

What should I consider?

Most environmental factors have an impact on classrooms only at the extremes.

Air quality is likely to be the most significant factor affecting learning, particularly where there is poor ventilation or high levels of dust and other pollutants.

High levels of external noise may also have a negative effect on pupils’ performance.

If you have a new learning environment, it provides an opportunity to change the expectations and behaviour of pupils, but it is unlikely to have a direct impact on learning without other changes. Have you considered how you will take advantage of any new environment to bring about improvements in these expectations and behaviours?
