The researcher has adopted the experimental approach through the designation of a programmed course on the second class syllabus of chemistry, using such aids as video, overhead projector and slides projector, two groups of students were exposed to this program: the group taught with aid of such equipment is called the experimental group, wl1ile the group from which the equipment were hidden is called the controlling group. The researcher has also adopted the descriptive analytical approach to describe and explain the phenomenon in question.
