When assessing the classroom environment, temperature is a vital concept as it can affect student's behaviour and in return their ability to take on knowledge. Marsh (2008) states that "Common sense would indicate that there is a fairly limited temperature range in which school students might be expected to work at their best". She explains that high temperatures can cause some students to be irritable and uncomfortable and in extreme cases both lethargic and nauseous. As well as cold temperatures that may bring out aggression and negative behaviour in some students within the classroom. The temperature of a classroom can be altered through the use and implementation of osculating ceiling fans, oil and gas fired heaters and air-conditioning. Marsh (2008). It is the responsibility of the teacher to be aware of the possibilities of temperature stress if too high or low temperatures prevail and adjust their activities accordingly. Temperature is a vital aspect on the classroom environment. It can alter how a student feels and in return their attitude to school and education. Therefore temperature has considerable impact on a student's ability to learn comfortably and efficiently.
