Let's understand the concept of Growth and Development. Growth refers to a physical increase in some quantity over time. It includes
changes in terms of height, weight, body proportions, and general physical
In Encyclopedia Britannica, growth is defined as “an increase in size or the
amount of an entity”. It means growth involves all those structural and
physiological changes that take place within an individual during the process of
maturation. For example, growth of a child means the increase in weight, height
and different organs of the child‟s body.
Hurlock has defined Growth as “change in size, in proportion, disappearance
of old features and acquisition of new ones”.
Growth refers to structural and physiological changes (Crow and Crow, 1962).
Thus, growth refers to an increase in physical size of whole or any of its part and
can be measured.
Concept of Development
Development refers to the qualitative changes in the organism as a whole.
Development is a continuous process through which physical, emotional, and
intellectual changes occur. It is a more wider and comprehensive term than growth.
It is also possible without growth.
In Webster‟s dictionary development is defined as “the series of changes which
an organism undergoes in passing from an embryonic stage to maturity.”
In Encyclopedia Britannica is the term development defined as “the
progressive change in size, shape, and function during the life of an organism by
which its genetic potential are translated into functioning adult system.” So, development includes all those psychological changes that take in the functions
and activities of different organs of an organism.
Development is a continuous and gradual process (Skinner).
According to Crow
and Crow (1965) development is concerned with growth as well as those changes
in behavior which results from environmental situation.”
Thus, development is a process of change in growth and capability over time
due to the function of both maturation and interaction with the environment.
