Definition of Education
Education can be defined as a continuous process that aims at
bringing about desirable changes in the behaviour of learners on
a relatively permanent basis and which are evident by way of
acquisition of knowledge, proficiency of skills and development
of values.
History of taxonomy
of educational objectives
Since a long time, organised educational system is facing
difficulties with student evaluation. A group of educational
psychologists took up the challenge of infusing transparency in
teaching and evaluation. Thus, at the convention of American
Psychological Association in1948, a group of teachers decided to
adapt the model of taxonomy used in biology for educational
practices. They described this classification Taxonomy of
Educational Objectives. This informal group consisted of
Benjamin Bloom, Max D. Englehart, Edward J. Furst, Walker H.
Hill, David Krathwohl and Bertran B. Masic among others.
Their findings were published in
the book –
Taxonomy of Educational Objectives: The Classification of
Educational Goals, handbook 1: Cognitive Domain in the year
1956. This group of psychologists identified that most of
educational objectives can be grouped under three headings –
cognitive, affective and psychomotor. The cognitive domain,
according to this book includes such educational objectives as
dealing with recall or recognition of knowledge and development
of intellectual abilities and skills. The educational objectives
in affective domain are concerned with ‘changes in the interest,
attitudes and values, and the development of appreciations and
adequate adjustments’. The educational objectives belonging to
psychomotor domain refer to ‘the manipulative or motor skill
area’.
Further, this book explained the various levels of cognitive
domain. The hierarchy of objectives in affective domain were
explained in Taxonomy of Educational Objectives: The
Classification of Educational Goals, Handbook 2: Affective
Domain that was published in the year 1964.
This group did not explore the hierarchy of educational
objectives in psychomotor domain. Many others attempted to
develop this hierarchy and in the year 1972, Elizabeth Simpson
presented the levels of objectives psychomotor domain. The
taxonomy marked an important milestone in the field of higher
education. Since learners in higher education are adults, and
seek reasons and purpose for their learning, educational
objectives and their hierarchy provide a useful benchmark.
Aims and Objectives
Definition of aim
Aim can be defined as a Broad statement of educational activity,
e.g., to understand disease. It describes what one intends to
achieve at the end of an educational activity.
Definition of objective
Objective is a precise point in the direction of aim, e.g.,
identify uncommon symptoms. It can be defined as a statement of
intent in an educational context. Other terms that are
synonymous with educational objective are – teaching objectives,
learning objectives, intended learning objectives, enabling
objectives, instructional objectives, curriculum objectives,
terminal objectives, operational objectives, performance
objectives, outcomes, competencies, etc. Of these, the terms
performance objectives and competencies refer more specifically
to objectives in psychomotor domain.
Educational objective can be defined as a statement of intent in
an educational context,
which
is demonstrable and measurable on predetermined parameters.
Thus, educational objective is a statement that clarifies the
complete range of activity and expected performance outcomes.
Functions of objectives
o
Purpose for teaching
-
Direction to teaching
-
Teaching made easy
-
Structure for teaching
The sequencing of objectives not only makes it easy to teach,
but also provides a comprehensive structure to teaching.
Layers
of educational objectives – core, intermediate, peripheral
Educational objectives determine learning contents. Because
educational objectives determine what has to be learnt, it
becomes necessary to know how much has to be taught / learnt.
This classification of learning is made under three headings –
must know, desirable to know and nice to know. This
classification is equally applicable to each of the three
domains of learning. The ‘must know’ segment consists of
educational objectives that represent the core competences of
the discipline. The learner must acquire the knowledge, skill
and attitude listed in this category, if he / she has to be
certified as competent / successful. These comprise of 70% of
the total statements of educational objectives in the
discipline. The other category is ‘desirable to know’, which
constitutes 20% of educational objectives. This includes
statements, which are not core competences, but something beyond
it. These objectives complement the core competences and may
become core objectives in higher levels of learning. ‘Nice to
know’ consists of objectives that are of ‘general knowledge’
interest. The significance of must know category is to ensure
that the student passing out with a health sciences degree must
have the basic and necessary competences to practice and provide
health services competently and comprehensively. The purpose of
including desirable and nice to know components is to
differentiate the exceptional learner from the average ones for
awarding grades in certifying exams.
Levels of educational objectives – institutional,
departmental and specific learning
Educational objectives can also be classified at three different
levels. The statements in this classification are more in the
form of goals than objectives, as explained earlier to
differentiate goal / aim and objectives.
The most broad and general from of goals are said to be
institutional or course goals. These list the competences that a
graduate has to acquire at the end of the course of study. These
are mainly drawn from the national health policy and the
strengths of the health sciences discipline for which the course
is being prepared. While listing these goals, not only the
current health needs, but also the future needs of the community
have to be kept in mind, so that the course does not become
obsolete and lose its relevance to society.
Departmental goals refer to the statements made for the subject
/ department in the context of the course. For example, anatomy
is taught for various health sciences disciplines like medical,
dental, nursing, physiotherapy, etc. But the teaching of anatomy
in each of these disciplines determined by the course goals.
There are situations, where goals of two or more departments
within a course may overlap or complement each other. For
example, the departments of Community Medicine and Paediatrics
may share the goal for immunisation. Or the departments of
Community Medicine and OBG may share the goals for Family
Planning. Speaking of the homeopathic course, the departments of
Community Medicine and Homeopathic Philosophy may share the
goals of prevention of epidemics. The statements, which express
these shared goals, are known as interdepartmental goals. These
are at the same level as departmental goals.
Specific learning goals are same as instructional objectives.
These are the specific statements, which are written for each
departmental goal. These explain the precise and specific
performance that is expected of the learner in the department at
the end of a specified educational activity.
SLOs or Educational Objectives as they are more conventionally
known, are explained in three different domains – cognitive,
affective and psychomotor. The significance of knowing domains
of learning is the possibility to plan the educational activity
in an accountable manner. Such a planned educational activity
provides space to think, understand and justify teaching /
learning. In the absence of planning, the entire exercise may
become vague, opinion based and dogmatic. As the saying goes,
‘if you fail to plan, you plan to fail’.
Domains of Education
Educational activity is broadly classified into three domains –
cognitive, affective or psychomotor, depending on the type of
intended learning objectives – whether it is acquisition of
knowledge, development of attitude or proficiency of skill.
-
Cognitive domain is about learning the behaviours that involve
thinking, understanding or explaining. It ranges from simple
recalling of facts to implementation and justification of
ideas and concepts.
-
Affective domain includes the learning behaviour that involves
demonstration of feelings / values towards facts or concepts.
It ranges from receptivity for people or events to automated
empathy for them.
-
Psychomotor domain includes all the skill based performances
like eye – hand / foot co-ordination.
Characteristics of educational objectives
Relevant – It is already noted that while stating educational
objectives we have to keep in mind the national health needs.
Any effort made towards realising such health needs adds
relevance. It can therefore be said that relevance of
educational objectives depends on the extent to which these
statements conform to the national health needs. Relevance of
educational objectives is a three tier process – first determine
course goals, second the departmental ones and finally the
specific learning goals. Thus, educational objectives that are
written can be said to be relevant.
Valid – It is the degree to which the statement conforms to the
domain to which it belongs.
Clear - The words must be precise and sentences clear. The idea
is that message has to reach clear and correct. There should be
no room for confusion, misinterpretation or vagueness. The major
ingredient of any educational objectives statement is an active
verb. The entire statement revolves around explanation for the
verb, which must be clear and unambiguous.
Feasible – The statement has to tell what is possible to do,
both in terms of human capacity and resources / infrastructure
available.
Observable – The very definition of learning is change in
learner behaviour. Thus, to know whether learning has taken
place, it is necessary to observe the changes that have taken
place. Therefore, educational objectives have to be stated in
terms that are observable.
Measurable – Measurability does not mean that learning has
always to be quantitative. But to know whether learning has
taken place, one has to measure the extent of change. Learning a
skill could be qualitative, but the time taken to perform the
skill before and after a learning session could be used as a
benchmark to measure qualitative change.
Elements of educational objectives
Act
– What the learner will be able ‘to do’ at the end of a learning
session. This could be in any of the three domains. Depending on
the domain, the appropriate verb has to be identified to state
the act.
Content
– It is the performance that learner is expected to demonstrate.
Condition
– The conditions under which the performance is done. It
includes the enabling and restraining factors. It also denotes
the range of manoeuvrability.
Act, Content and Condition
together constitute the
Task
Criterion – This is the degree of freedom allowed for
performance.
