EFFECTS OF PRACTICAL METHOD ON THE EFFECTIVE TEACHING OF PHYSICS IN SENIOR SECONDARY SCHOOLS. (A CASE STUDY OF OJODU LOCAL GOVERNMENT AREA IN LAGOS STATE)

The study of physics is generally recognized to be quite old but there are differences of opinion as to how old. Some would argue that physics began in Western Europe during the Renaissance with the work of Copernicus, Galileo, Kepler, and Newton. Others would trace the beginnings back to the early Greeks and credit he Ionian Thales with being the world’s first physicist. For me, physics is much older having begun with man himself. Man became a scientist for the sake of his own survival. The very first tool-makers were scientists. They discovered that certain objects in their physical environment were useful for performing certain tasks. Having learned this they went onto improve on these found objects first by selecting objects more suitable for the task involved and later actually altering the materials they found to produce manufactured tools. The type of reasoning involved in this process is typical of the scientific method in which an observation of nature is made. For early man, the generalization made was not a theoretically but rather a useful tool.Examples of this form are found in the mythology of ancient Egypt, Greece, India, Babylonia,Polynesia and North America. The other classes of myths include creation by an earth diver,creation from a cosmic egg, creation from chaos, and creation from nothing. In the earth diver myths an animal or god dives into a body of water to retrieve a tiny particle of earth which then expands to become the world. The cosmic egg myths tell of an egg, usually golden, which appears at the first moment of the universe. The egg breaks open and the events of the universe unfold. In one version the upper part of the egg shell becomes the heavens and the lower part, the earth. At the beginning of the creation from chaos myths there is disorder or chaos sometimes depicted as water from which a creator creates the universe. Finally, in the creation from nothing myths,which are closely related to the chaos myths, the original starting point of the universe is a void.The best known example of this group to Western readers, of course, is Genesis, where we read “In the beginning, God created the heavens and the earth. The earth was without form and void anddarkness was upon the face of the deep”.
