WHAT IS DESCRIPTIVE RESEARCH METHOD ? A descriptive study is one in which information is collected without changing the environment (i.e., nothing is manipulated). It is used to obtain information concerning the current status of the phenomena to describe "what exists" with respect to variables or conditions in a situation. Present trends, beliefs, public mind, their viewpoint and attitudes, their effects or development of new trends are described Ex. : Instance of road accident.

DEVELOPMENTAL STUDY METHOD The longitudinal , cross-sectional and trend studies of descriptive research are together known as developmental research. It examines the change in specific characterstics and the trends of development in context of time. the systematic study of designing, developing, and evaluating instructional programs, processes, and products that must meet criteria of internal consistency and effectiveness
TYPES OF DEVELOPMENTAL STUDY METHOD LONGITUDINAL DEVELOPMENTAL STUDY METHOD CROSS-SECTIONAL DEVELOPMENTAL STUDY METHOD TREND RELATED DEVELOPMENTAL STUDY METHOD
LONGITUDINAL DEVELOPMENTAL STUDY METHOD Borg and Gall : “An individual or a group is studied longitudinally when the researcher follows the same person over a period of time. In long term developmental study a researcher has to wait for a prolonged period to get the initial and final information”. The same type of information is collected from the same subjects of a sample, at various interval of time in context of certain variables, and in which the trend of development is examined in context of time is called longitudinal developmental study method.
LONGITUDINAL DEVELOPMENTAL STUDY METHOD Study on the same subjects of the same group is done for a long period of time. Continous study of various development is done. Sample is small Repeated observations are taken at different time. It is expensive. Repeated interview is essential. Ex.

CROSS-SECTIONAL DEVELOPMENTAL STUDY METHOD Cohen and Manyon , “When the different respondent are studied simultaneously in practical time, then it is called Cross-Sectional Study”. To compare the subjects of samples representing various stages of development at a particular time and to evaluate the changes occuring at a specific time.
CROSS-SECTIONAL DEVELOPMENTAL STUDY METHOD Study is done on various subjects at one time. The rate of development is studied. A large sample is selected. Observation is taken at a same time. Interview is done once or twice. Less expensive. Ex.
