A classroom or schoolroom is a room dedicated primarily to teaching or learning
activities. Classrooms are found in educational institutions of all
kinds, including public and private schools, home schools, corporations,
and religious and humanitarian organizations. The classroom attempts to
provide a safe space where learning can take place uninterrupted by
other distractions.
Types of classrooms
For lessons that require specific resources or a vocational
approach different types of classrooms both indoors and outdoors are
used. This allows for learning in an authentic context that fosters the
natural development of the particular vocational skill.[1] This is known as situated learning.
Classrooms can range from small groups of five or six to big classrooms
with hundreds of students. A large class room is also called a lecture hall. A few examples of classrooms are computer labs which are used for IT lessons in schools, gymnasiums for sports, and science laboratories for biology, chemistry and physics. There are also small group classrooms where students learn in groups of about 7 or 8.
Typical equipment
Most classrooms have a large writing surface where the instructor or
students can share notes with other members of the class. Traditionally,
this was in the form of a blackboard but these are becoming less common in well-equipped schools because of new alternatives like flipcharts, whiteboards and interactive whiteboards. Many classrooms also have TVs, maps, charts, Pencils, books, monographs and LCD projectors for presenting information and images from a computer.
In the past, schools and institutions would often have one computer
lab that served the entire school only at certain times of the week.
Computers in the classroom itself increase interest in learning and
awareness of the importance of what is being taught. Children are less
likely to feel that a subject is archaic if the teacher uses new
technological instructional techniques, increasing the students’
interest in learning something new. A study shows that children taught
with the integration of technology improved in testing significantly
over those who did not.[2]
The Classroom of the Future is an education project in the United Kingdom.
Twelve local education authorities sharing about £13 million to develop
around 30 pilot projects. The buildings have roughly three classrooms
in them, which contain enough laptops or tablet computers
for each person. The classrooms are designed to be environmentally
friendly. The buildings contain toilets which use rainwater, and use
windturbines and solar panels for electricity and heating.
Decor and design
The layout, design and decor of the classroom has a significant effect upon the quality of education.[citation needed]
Attention to the acoustics and colour scheme may reduce distractions
and aid concentration. The lighting and furniture likewise influence
study and learning.[citation needed]
Historically, relatively few pupil centric design principles were
used in the construction of classrooms. In 19th century Britain, one of
the few common considerations was to try and orientate new buildings so
the class windows faced north as much as possible, while avoiding west
or southern facing windows, as in Britain northern light causes less
glare.[3]Desks were often arranged in columns and rows, with a teacher’s desk at the front, where he or she would stand and lecture
the class. Little color was used for fear of distracting the children.
In the 1950s and 60s cheap and harsh fluorescent lights were sometimes
used, which could cause eyestrain. Research has suggested that optimal use of daylight, acoustics, color selection and even the arrangement of the furniture in the classroom can affect pupils academic success.
Lighting
The use of daylight in school buildings is not a new concept. In
Great Britain, a common principle in the 19th century was to avoid glare
by having as many of the class's windows facing north as possible. From
the early 20th century there was greater emphases on the importance of
daylight but less concern about glare, so west and south facing windows
became more common. From 1945 regulations were put in place mandating a
minimal 2% penetration of daylight into British classrooms.[3] In the US, regulations on the amount of lighting were introduced in the late 1950s.[4]
Until the 1960s, air conditioning was not used, so windows provided not
only sunlight, but necessary air circulation as well. With the advent
of air conditioning, school buildings were built with many classrooms
that did not include windows.[5] High ceilinged rooms lit with daylight were eventually replaced with generic "shoebox classrooms." [4]
Several studies done on elementary school students attempt to measure
student performance in classrooms where daylight is present when
compared to classrooms without daylight.[5]
Classrooms with skylights rather than windows have been studied for
several reasons. Windows provide a view, which may be distracting, as
well as introduce air quality issues that are not a problem with
skylights. A study found that the use of skylights improved test scores
in reading by 8.8 points and in math by 12.3 points. This translates to a
19% faster learning rate for reading and a 20% faster learning rate for
math. The average elementary school child will increase 1 to 1.5 points
per month on test scores in math and reading in a classroom with no
daylighting. The same child will improve twice as fast, gaining 2 to 3
points per month in a classroom that includes daylight.[6]
Acoustics
The acoustics of the classroom are very often overlooked, but are an
important part of the success of a child. Choosing only materials that
cause sound to reverberate, such as tile floors and hard wall surfaces,
greatly increases noise levels and can prove detrimental to learning.
One study of hyperactive versus control groups of children found that
white noise has no impact on either group, but that auditory stimulation
such as distant conversations or music has a negative effect on both
groups of students. Children with attention deficit disorder scored
higher on tests when white noise was being pumped into the classroom
than when music was played. The control group of children as well as the
hyperactive group of children averaged the same test scores when there
was no sound as when white noise was being played.[7]
By utilizing soft surfaces, especially on the floor, the sounds
within and outside of the classroom will be diminished, taking away from
the distractions facing students and improving not just the test scores
of hyperactive children, but those without attention deficit disorder
as well. Although carpet is an obvious choice for sound absorption, it
may not be suitable for high traffic areas like hallways. In such cases,
other sound absorbing materials, such as cork, can be used. The use of
sound absorbing ceiling tiles may also be a wise choice for areas where
carpet cannot be used for practical purposes.
Color selection
Color theory refers to the psychological effects color has on the
human body. Red is said to increase both aggression and appetite, a poor
combination for a school’s interior. Yellow increases adrenaline levels
and is also undesirable for a school setting. Blue supposedly calms the
brain, which is a positive for the classroom.[citation needed]
However, blue also is associated with cold and sadness and elongates
the sense of time, which would make a blue classroom tortuous for
students (Vodvarka, 1999). Warm colors are often favored by students,
making them more alert and increasing brain activity, which helps in
increasing test scores. Cool colors had the opposite effect.[8]
By balancing warm and cool colors, bright and subdued, a pleasing
effect can be achieved that will reduce absenteeism in schools and keep
the students focused on what the teacher is saying. Test scores go up
when children are not in a stark white environment, which can feel
sterile and cold.[9][10]
Furniture arrangement
Traditionally, classrooms have had one setup: straight rows of desks
facing the front of the classroom. While this keeps attention focused on
the teacher, it does not allow for group work or discussion. One study
found that students who sat at desks arranged in a circle were more
likely to listen actively and participate in discussions, and less
likely to withdraw from the group. However, more instances of on-task,
out-of-order comments were recorded. In rows, students respond less
during discussion, but are also less disruptive. Instances of cheating
went up when desks were placed in clusters and down when placed in a
circle. When the children can see everything around them, except their
neighbor’s paper, when desks are in a circular pattern, they rely more
on their own knowledge and that confidence causes test scores to rise
when compared with scores when desks are arranged in clusters or rows.[11]
Another classroom seating alternative would be the use of tables
instead of desks. Desks often have small writing spaces that do not
allow room for students to comfortably write. Desktops usually have room
for only one notebook or one book. This can be a disadvantage to a
student who needs to look at more than one object while a teacher is
lecturing. Also, it can be a great discomfort if there is not enough
room for students to comfortably take notes. Tables allow students to
spread out their learning materials and sit comfortably. As for small
group discussions, tables can provide great spaces for two to four
person discussion groups. However, tables can also be a disadvantage in
the classroom when a teacher would like the students to move into a
circle for an activity or discussion.
