Lack of Adequately Equipped Biology Laboratories in Secondary Schools
With
unnumbered botanical (for plants) and scientific (for animals) names, chemical
transactions and transformations and biotic and abiotic intra and
inter-relations, biology will only amount to boredom if there are no well
equipped laboratories to perform experiments which will internalize the
principles and practices of the subjects. Bad enough, there are no laboratories
in many secondary schools, while the available ones are poorly equipped or
mismanaged. This is a serious set-back to the teaching of biology.
Okeh
(2008) argued that science subjects are not to be taught outside laboratories.
He further declared that the out-of- laboratory teaching of biology is the
chief cause of biology students inadequacies in the art of instrumentation and
their poor performance in biology examinations.
Every
tradesman uses tools. A teacher is a worker like the farmer. He uses his own
brand of tools which are instructional materials.
According
to Nwokolo (2005), instructional materials are those materials employed by a
teacher to improve the effectiveness of instruction. The materials helps to
maximize teaching and learning because to appeal to a variety of senses. They
could be visual aids, auditory aids, audio-visual materials and stimulation devices.
The biochemical changes that occur in biology laboratories also comes with
notable sensory effects that are identifiable and so improve students’
understanding, assimilation retention and consequent reproduction of whatever
has been instructed.
However,
the availability, technicality and willingness of biology teachers, science
laboratory technicians and assistants and laboratory attendants and even
laboratory equipment are grossly inadequate. This is a minus to effective
teaching and learning of biology and the achievement of the subject in a
broader view.
Imoh
(2006) complained that some untrained teachers who are engaged to teach in our
schools and colleges cannot use instructional materials and laboratory
instruments properly. Some of them think that they are more time consuming
owing to their ignorance, they do not appreciate the place of gadgets in
learning.
WAEC
chief examiners report 2001, 2002,2003) on the failure of biology candidates is
due to the fact that there are no laboratories for teaching through
participatory demonstration of biology. These show that lack of adequately equipped
biology laboratories contribute to in-effective teaching of biology and
students poor performance in its examinations.
