Technical & Operational
Definitions
(English 10 Q4)
Jovelyn B. Arellano
Subject Teacher
Objectives:
At the end of the lesson, the students are
expected to:
• Define technical and operational definitions

• Distinguish technical and operational definitions
• Give technical and operational definitions of
words found in a Science Laboratory
EN10V-IIa-13.9
Let’s watch this video!
HOW TO DEFINE WORDS
What could happen when a word or
phrase is not understood in the same
way by everyone on the team?
It could lead to misunderstanding.
TRUE OR FALSE
1. Operational definition is the specific

meaning of a word or phrase given in their
specific context.
1. Operational definition is the specific
meaning of a word or phrase given in their
specific context. TRUE
2. The purpose of defining the term in a
research study is to keep them
unambiguous, thereby reducing errors.
2. The purpose of defining the term in a
research study is to keep them
unambiguous, thereby reducing errors.
- TRUE
3. An operational definition is the
same with conceptual definition.
3. An operational definition is the
same with conceptual definition.
- FALSE
ACTIVITY
Pick a paper with a word written on
it. Try to define it within 20 seconds.
1. Where you able to give the
definition within 20 seconds?
2. Did you find it hard to give the
definition for the word?
3. What kind of definition did you
give? Was it technical or operational
definition?
Let’s Study!
DEFINE – (verb) to state or

describe exactly the nature,
scope, or meaning of
something
TECHNICAL DEFINITION
- mostly refers to the aspect of explaining
or describing any technical terms or
terminology. Technical definitions could be
used in expanding the vocabulary since
most of these terms are explained in the
exact manner. Examples include the terms
and definitions of the words found in
dictionary.
Examples:
1. Carbohydrates are food group including sugar,
starch and cellulose.
2. Influenza is an acute highly contagious infection

of the respiratory tract which occurs sporadically
and lasts up to months.
3. Cellphone is a portable device for use in a cellular

system.
In writing TECHNICAL DEFINITION we
must:
2 TYPES OF TECHNICAL DEFINITION
1.PARENTHETICAL DEFINITIONS
2.SENTENCE DEFINITIONS
PARENTHETICAL DEFINITIONS
SENTENCE DEFINITIONS
Operational definition, on the other
hand, is more on the application of the
word. For example, these may include
the various attempts to define or
explain a certain process and its
properties including but not limited to
the characteristics of the event itself.
For example, the technical definition of
a computer is a device or machine used
in performing, assessing, evaluation and
following commands set by the users.
The operational definition of a computer
is something used in doing homework or
browsing the internet.
4 Purposes of an Operational Definition in
Research:
1. It establishes the rules and procedures the
researcher uses to measure the variable.
2. It provides unambiguous and consistent meaning to
terms/ variables that otherwise can be interpreted in
other ways.
3. It makes the collection of data as well as the analysis
more focused and efficient.
4. It guides what type data and information we are
looking for.
Example context where operational
definition is necessary:
SUMMARY
Technical definition mostly refers to the aspect of
explaining or describing any technical terms or
terminology. Examples include the terms and definitions
of the words found in dictionary.
Operational definition, on the other hand, is more on the

application of the word. For example, these may include
the various attempts to define or explain a certain process
and its properties including but not limited to the
charactertics of the event itself.
TASK 1 – Analyze the sentences below. Write TD if
the concept is defined technically and OD if it is
defined operationally.
1. The mass of the body on earth and the moon are the same.
2. Virtual meeting is the gathering of people online to avoid
the spread of COVID-19.
3. Depression (major depressive disorder) is a common and
serious medical illness that negatively affects how you
feel, the way you think and act.
4. Literacy is the application of the knowledge gained.
5. Education is the process of receiving systematic
instructions.

Assignment:
Imagine that you are working in a Science
Laboratory. Write 5 words that you use or
encounter in your workplace and write the
technical and operational meaning of each
word. Write it in ½ sheet of paper.
