According to Smythe Liz Ph.D.
and Gidding Lynne Ph.D., “qualitative research studies is the study about the experiences of real people, the study of recognizing how complex life is, it is the study of wanting to uncover understanding that improves practice and holding with some of the big and elusive questions of life.” The difference between qualitative and quantitative research studies is that quantitative research involves gaining an in-depth understanding of human behavior and governs it.
Quantitative research is more subjective in describing a problem and condition from the point of view of those experiencing it and observations and review of records or documents for numeric information. It is objective, provides an observed effect of a program on a problem or condition. It is number based. As a physician, one idea is following the age groups 15, 20, 30, 40 or 45 will be to undergo a check-up to ascertain the capability of their body system in caring pregnancy. Attending a prenatal create an awareness to knowing the advantages and disadvantages of having a baby at their ages. For instance, at 15 years age, girls are at greater risk having a very narrow cervix which may make delivery complicated and may have a low weight baby. Age 20-24 are considered the prime age for childbearing a healthy baby. However, age 35 and above stands a chance of miscarriages etcetera.
In explaining how the environment in which they grow up influence children’s heredity, one has to consider nature and nurture controversy. The notion of nature, therefore, refers to biologically prescribed tendencies and capabilities individual possess, which may unfold themselves throughout the course of life. Nurture, by contrast, refers to various external or environmental factors to which an individual is exposed from conception to death. In this case, nurture has upper hand influencing children’s heredity in that in a home where an uncle smokes, cigarettes and there are children or set of twins, it is possible to see a child who admires that habit thereby tries to imitate the uncle by smoking. It could be one of the twins smoking when the other is not. In this case, one can say that what children see an adult do in a home or around the environment can change the character of a trained child from good to bad or vise verse.
If I should choose a theory that represents my own viewpoint of human development, I would like to choose a single theory by Bandura a social learning theorist who discovered that children learn through watching modeled behavior. Children gradually become more selective of what they want and imitate them. Through feedback, children develop personal standard and sense of self-efficacy.
