Learnometer is a unique combination of hardware, software and analysed data that help learners, and thus schools, perform better by optimising physical environments for learning. The process of making learning better also engages everyone as reflective learners, improving their learning further.
Our research, and others', confirms that poor light levels, the wrong temperatures, inappropriate sound volumes and rhythms, humidity, air pollution, Co2, and air pressure can all impair learning. Our Learnometer research tool automatically samples your classroom environment, and makes suggestions through a unique algorithm as to what might be changed to allow students to learn and perform at their best.
Cloud-based logging allows you to see, at a glance, how your environment looks, and lets you compare it with benchmark environments. You can analyse general learning spaces, or specific areas like examination and test rooms. Changes you make can be evaluated and compared, and then finessed over time.
Poor lighting is a significant barrier to learning. Our work is confirmed by recent school environment studies, and detailed research for other working environments. For example recent research confirms evidence that good lighting significantly influences reading vocabulary and Science test scores (Barrett et al., 2015). Learnometer reports lumen (lux) levels throughout the day and plots them constantly and automatically for you wherever it is installed.
Our guide would be above 250 lux for engaged conversation, and above 450 lux for close work like writing or computer use.
Many classrooms are either too hot or (less damagingly) too cold for learning. Even though national law (eg UK) does not usually give an upper limit for temperature, research suggests that between 18 and 21 degrees is ideal for learning. Learnometer contains a sensitive digital thermometer and hygrometer which tell you the temperature of your classrooms throughout the day. You’d be amazed how much it changes.
Joshua Graff Zivin, of UCSD, and two colleagues in an NBER Working Paper noted that "we find that math performance declines linearly above 21C"
Studies confirm that the classroom sound signature can affect how well students achieve (Picard and Bradley 2001). Learnometer constantly gives you automated feedback on sound volumes (including from the students!) and rhythms (for example from projector fans or air conditioning units) in your classroom, will highlight changes to be made, and plots the results of your changes by hour, day, and even year.
As a starting point we suggest that sound above around 72 decibels starts to be disruptive - although what the sound is matters too (for example is is hard to write when background music contains a familiar lyric). A simple guide for beats per minute is to stay below 80 bpm
Carbon Monoxide and Carbon Dioxide cannot be sensed by humans, both of course have the potential to kill, but at lower levels, Co2 will affect concentration.
Our pilot work suggested a correlation between absence / illness levels and high classroom Co2 levels (for staff and students) and we have been dismayed by the damaging levels we have observed in examination and test rooms. Learnometer logs and tracks the levels of Co, Co2 and particulate matter ("pollution") to help you identify airflow issues and optimum levels for learning and performance.
A useful guide would be to be aware that above as little as 1,000 parts per million (and arguably lower still) Co2 will be inducing sleepiness, poor concentration with abnormal heart rate and nausea. Problems ncrease towards 5,000 ppm which is a workplace limit in most countries, but which, disappointingly, many learning spaces often exceed daily.
This 2015 study from the Harvard School of Public Health found that carbon dioxide (CO2) has a worse, direct and negative impact on human cognition and decision-making than was previously understood.
When we began the learnometer project the link between wellbeing and pollution was clear, but pollution's impact on learning was largely hypothesised by us, without much good evidence. Since then however some substantial research projects, like this one from China, have suggested that high levels of urban pollution have a major impact on attainment - some children dropping a whole year of progress in their school lives.
Although it is unlikely that relocating a school will be possible (but see our remedies section), battles against planning approval for siting polluting industries near schools will be a lot easier to win, given clear pollution data from within classrooms. However, a little micro-research study at ARU's Cambridge campus has shown us that opening windows to let the heat and CO2 out, can let high levels of urban pollution in - a nice indicator of the complexity of all this which our learnometer and its algorithms might hopefully inform.
There is much we have yet to learn about air pressure, or indeed other variables captured by our little Learnometer research units. As you optimise your learning spaces, we will analyse the data aggregates too, and add them to the knowledge we are building for you.
At a common sense level many people complain of pressure related sinus headaches that can certainly cause distraction and, we might assume, a loss of concentration. Of course weather and altitude play a role in the pressure we experience. We might hypothesise that cultural norms from living at sea level, or at high altitude, will impact of our tolerance levels too.
Whilst we evolve our research and understanding, Learnometer will allow you to look at your own data too and to engage in your own practice based research.
To learn well is complex. Alongside the hard work, the pedagogy, collegiality, passion, delight, knowledge, joy, and engagement there is the detail of physical learning spaces themselves. Learnometer builds on work I have been involved in for three decades, designing better classroom environments and understanding how learner-led design increases achievement in measurable ways.
We’re now at an exciting point where the advent of affordable Internet connected smart devices has combined with further research on how factors such as light, heat and air-quality affect classrooms. The team at Learnometer have built some amazing devices to measure this data automatically, and we’d love to see them help your school.
There is plenty yet to learn, but by joining the Learnometer research family, you will be changing and improving learning forever, and informing significant change in your own learning spaces too.
