Is also called "fundamental research" or "pure research"
It is intended to add to the body of scientific knowledge by exploring the unknown. In other words, the results of basic research in theoretical knowledge have no immediate usefulness or value to man. An example is Boyle'slaw which states that the temperature remains constant, the volume of a confined gas is inversely proportional to the pressure.
Applied Research
this type of research involves seekingnewapplications of scientificknowledge to the solution of a problem, such as the development of a new system or procedure, the problem is identified and a new system or new method is applied in order to solve the problem.
It produces knowledge of practicalusetoman. Another example is the problem regarding crimes that are perpetuated by riding in tandem. To solve this problem there should be research conducted prohibiting the running of motorcycles with back rides.
Developmental Research/ Action Research
this is decision-oriented research involving the application of the steps of the scientific method in response to an immediate need to improve existing practices. In other words, if a researcher continues to find practical applications from theoretical knowledge and uses this existing knowledge to produce useful products it is called development research.
