HUMAN GROWTH AND DEVELOPMENT
HUMAN GROWTH AND
DEVELOPMENT
DEVELOPMENT
Progressive series of change that occur as a result of maturation and experience.
Qualitative change is the sequential and continuous process of change in any direction.
Progressive
Growth
Changes are directional, leading to something positive.
Quantitative change in size and structure-an increase in magnitude-in body size, intellectual ability or even social traits
Types of Changes in Development
Change in size – there is a change in physical and mental growth.
Change in proportion – physical development is not only limited to size it is also apparent in mental development
Disappearance of old features – some features that disappear.
Acquisition of new features.
Biological Factors of Development
Is the transmission of traits from parents to offspring. Characteristics of both parents
Heredity are passed to the child through the union of father’s sperm and mother’s egg cell to form a zygote.
Maturation
The unfolding of traits potentially present in the individual considering his hereditary endowment.
Biological Factors of Development
Environment
Learning
Includes all the conditions in the world that influence behavior, growth, development or life process in any way. The result of activities or day-to-day experiences on the child himself.
Biological Factors of Development
Chromosomes
Are threadlike bodies in the nucleus of cells. With in the nucleus are structure containing heredity factors
