EDUCATION AND KNOWLEDGE:
COGNITIVE DIMENSION OF EDUCATION.
A. Introduction
During the
discussion of Criteria of education as propounded by R.S. Peters and the Dimensions
of Education by Njoroge and Benaars we inferred that Education deals with
knowledge acquisition and as such, it falls under Epistemology which is one of
the branches of Philosophy proper. Epistemology deals with philosophical
reflection of knowledge. It studies the nature,
sources and validity of the knowledge.
B. Concerns of
Epistemology
Epistemology occupies itself with, among others, the
following questions:
(a) What is
knowledge?
(b) What is the nature
of knowledge?
(c) What are the
principles of knowledge?
(d) What is truth?
(e) How do we
come to know?
(f) How can we
verify knowledge?
(g) How do we know
that we know?
(h) What can we really
know?
(a) What
is Knowledge?
The concept of verb
‘to know’ can be sub-divided into three aspects:
v
Knowing that – facts, information or details about something.
v
Knowing how – having the ability to demonstrate,
possession of a skill or technique.
v
General familiarity – mental grasp of either information or skills without sufficient
details.
(b)The Conditions of Knowledge
According to I.
Scheffer (1965), there are three conditions of knowledge: 1. Belief Condition
2. Truth condition and 3. Justification
1 . Belief Condition
To believe is
however not to know: it is just the beginning, although more is required than
mere belief. Believing is more of a psychological state of mind and knowing is
more than the strongest conviction. This is necessary for
communication/teaching as it helps one to demonstrate an element of originality
and subjective ownership of information.
2. Truth Condition
It refers to the
actual truth of what one asserts. Knowing thus points to something independent of the individual/subjective claiming to know – points to the truth of
the matter. What one ‘believes’ may not be necessarily the truth as it is
universally or objectively known. To know is thus more than believing: it
implies that there is actually truth: a matter of true belief. To establish the
truthfulness of a proposition/statement, it must be subjected to the following
theories:
i.
Correspondence theories of truth: whatever is claimed to be true
must correspond with reality i.e. must agree with what can be empirically verified, measured, observed. The major
impediment to this theory is that our verification tools/observation are at
times faulty. It is possible to perceive reality wrongly.
ii.
Coherence theory of truth: whatever is claimed must
cohere/agree with what is already accepted/admitted as truth. Any new knowledge
is validated on the basis of the existing knowledge. However, this theory has
limitations. Whatever is known may be untrue or false, one could possibly be
mistaken e.g. the Galileo’s case with the Roman Catholic Church.
iii.
Pragmatic theory: whatever is of utility/value
works and is useful or beneficial or true
iv.
Semantic Theory: Truth is based on language use
and manipulation
3 Justification/grounds
condition
The claimant
must be able to cite evidence and evidence of the right kind to support/justify
his claim. Absolute certainty is difficult to attain because human knowledge
tends to be limited. Certainty thus remains uncertain or hypothetical. One must
always be prepared to review/reconsider their knowledge in the light of new
evidence though adequacy of evidence is many times a serious problem. Although
every claim to knowledge must be based on some grounds, there are statements
which do not necessarily require evidence. E.g. analytic propositions that are
self explanatory statements; statements based on existential and consciousness
i.e. I feel frustrated. While we insist on evidence, we should exempt analytic
proportions based on existential realities.
c. Sources of
Knowledge
i. Authority
as a Source of Knowledge
It
refers to people or individuals who occupy superior
positions in relation to the claimant. Knowledge is here based on what
those in authority have said i.e. I know it because so and so says so. People
in authority include parents, teachers, preachers, authors, experts and journalists. Authority is simply believed.
Individuals rely on authority because they lack time to verify for themselves.
Also, there tends to be lack of commitment to question issues and search for
clear knowledge. In a classroom situation, students tend to believe wholesale
whatever the teacher says. There is therefore a need for care and concern for
truth on the part of the teacher.
Precautions
when dealing with authority:
v The
person whose statement we believe must be a relevant authority in the field.
v Authorities
sometimes disagree. There is need to be careful: sometimes judgment needs to be
suspended before arriving at a conclusion.
v Verify
information. Whenever we accept the other people’s statements, we should
establish whether they are actually true.
v No
matter how reliable an authority is, it cannot be the primary source of
knowledge.
ii.
Revelation as source of Knowledge
This
is a source of knowledge from which various religions derive their basic dogma.
Although the truths recorded in sacred books are considered eternal, the
language in which they are written is not hence religious scholars spend much
time arguing over the precise meaning of words and expressions in the sacred
textual interpretation. The purpose this is to bring to light the external
truths that are locked in these words.
iii.
Sense experience
Common
sense tells as that sense experience is the starting point of knowledge for we
begin to be conscious at all when we begin to exercise our senses.
If
we merely looked at what occurs in our own lives, and reflect on our own
experience, we realize that our minds, at the onset, are no more than “white
paper, void of all characters, without any ideas” (Locke’s famous Tabula rasa, that is blank tablet) all
we know or think about is ideas which come from experience.
iv.Intuition
The
immediate knowledge of truth, without the aid of any reasoning and without
appeal to experience is called intuition. It is sub-conscious activity, which
instantly reveals into consciousness that which the mind has been at grips for
a period of time.
v.Human
reason
The
view that reason is the sole source of knowledge is known as rationalism and
the proponents of this doctrine are called rationalists. The human mind has innate structure that is responsible for a
variety of intellectual competence.
The
mind, by its reasoning power has instinctive capacity to discover knowledge
within itself; knowledge is therefore a product of man’s power of thought and
explanation.
Plato
claimed that man’s knowledge is basically a recollection of the ideas which the
soul had known in the perfect world of ideas before it was buried in the human
body.
Education
therefore, is to focus on the soul with the view to helping it recollect as
much of that knowledge as possible.
Rationalists
claim that it is dangerous to rely solely on our senses as they are prone to
being highly insensitive and unreliable. Senses are capable of establishing
conflicting results about the same phenomenon depending on our location, health
condition and even attitude.

d. Knowledge and Curriculum
Generally, curriculum refers to
knowledge, beliefs, attitudes and skills which are considered desirable for
transmission to others. Knowledge is classified or categorized within the
curriculum based on the following criteria:
1. Language: each subject tends to have particular
language e.g.in mathematics we can consider -matrix, integers, numbers….
In religion, discourse may rotate around concepts like God, sin, grace, soul,
salvation, angels among others. Scientific language may employ jargons such as
observation, replication, data collection, validity and others. Knowledge of is
therefore crucial and without it other aspects of knowledge can only prove to
be impossible to grasp. This is further justified from the premise that humans
are symbolic and social beings. They interpret reality using symbols and convey
it to other using language as the most crucial of the symbols.
2. Methods of verification or testing: e.g. sciences depend on
empirical observation and tests on experiments while mathematics and religion
uses deductive reasoning. As such methods of verification and dissemination of
knowledge are logically laden . It is imperative that any curriculum should
therefore bring out clearly what is there to be known on procedural aspects of
investigation and dissemination.
3. Area
of specialization or subject matter: Physical sciences dealing with natural
world Social sciences concentrating on the world of culture, Philosophy and Religion
dealing with world views and mathematics dealing with the world of numbers.
Based on the above criteria,
the following classifications of knowledge have been enunciated:
a. Logic and mathematics.
b. Physical sciences.
c. Human sciences.
d. Aesthetics (e.g. fine arts)
e. Morality or
ethics.
f. Philosophy.
4. Theories of Assessment of Curriculum
(a)
The utilitarian curriculum: This means the curriculum that is useful to the
learner and one conducive to human happiness i.e. promotes the greatest amount
of happiness for the largest possible number of people. Such a curriculum includes
survival skills, social skills, and politics.
(b)
A curriculum for rationality (thinking systematically): It has to produce a
rational mind. In order to cultivate this certain subjects need to be
incorporated i.e. logic, mathematics, philosophy.
(c)
A heritage curriculum: The chief point of education is to bring children into
what exists as a public tradition of shared knowledge i.e. culture which refers
to the intellectual aesthetic, moral and material achievements of mankind.
5. Role of the learner
a.
Epistemology considers the learner as a knowing being and so an educable being(or
Homo Educandus)
b.
Epistemology anticipates that a learner be active both intrinsically and
extrinsically in the pursuit of knowledge
c.
Recognition of authority as a source of knowledge demands an appreciable but
open degree of respect towards the authority of the teacher and learning
resource materials.
d.
Intuition is valid source of creativity in Education.
6. Learning Environment
Different
epistemological systems call for various learning environments:
a. A realist/empircal
epistemology with its emphasis on sense experience as a primary source of knowing
advocates for a classroom environment with adequate teaching aids that appeal to the senses like photos, audio visuals, Tactile objects.... By
extension it envisions equipments for practicals as in the case of laboratories
and workshops
b. A rationalist
epistemology emphasizes reasoning and deductive argumentation. As such its
learning environment would be insufficient without books by renown authors. Books
are primary for a rationalist environment.
