Coping with the K-12 Dilemma
EMPTY YOUR CUP
An Old Buddhist Tale
Bruce Lee, the legendary
martial artist, once told a
story about a highly-
educated man who went
to a Zen teacher to ask
and acquire knowledge
about Zen.
As the Zen teacher began
to explain things, the man
would frequently interrupt
with remarks like, "Oh,
yes, we have that too…”
Finally the Zen teacher
stopped talking. He began
to serve tea. He poured
tea into the man’s cup.
He poured tea into the cup
until it was full, and then
kept pouring until the cup
overflowed. "Enough!" the
man once more
interrupted, "No more can
go into the cup!"
“Indeed, I see," answered the Zen teacher, "If
you do not first empty the cup, how can you
taste my cup of tea?"
A full cup cannot accept
anything more. Similarly,
a person who believes
that he had learnt a lot
cannot learn anything
else & will stagnate
quickly and not move to
higher levels.
ATTITUDE DETERMINES YOUR ALTITUDE.
A SMALL CHANGE IN ATTITUDE MAKES BIG
DIFFERENCE

Why is there a need to study TEST
CONSTRUCTION?
For every problem there is a solution. If you are not part of the solution then you are part of the PROBLEM.

Sample Test Question:
“The evaluation of pupils’
progress is a major aspect of
the teacher’s job.“Evaluating Educational Outcomes
(Oriondo & Antonio)
Explain the message of the comic strip.
Our students were trained to memorize information.
After they have memorized facts, then what?
Old belief about teaching .....
Education is a process where the notes of the teachers or the contents in the books are transfered to the notebooks of the students, without understanding them.
(Wiggins, 2009)
In your lesson plans, did you ever bother to ask this question:
• How do you know if you have achieved your desired result?
“A test is a sample of behavior, products, answers, or
performances from a particular domain” (Carrington, 1994)
“… it's a systematic method of eliciting performance which is intended
to be the basis for some sort of decision making" (Hughes, 1989).
“A test will predict performance levels, and the learner will somehow
reconstruct its parts in meaningful situations when necessary”
(McCann, 2000)
“ Testing is generally concerned with turning performance into
numbers.” (Baxter, 1997)
Guidelines for Test Construction

Motivate learners to review or consolidate specific material
Guide the planning/development of the ongoing teaching
Determine if the objectives
Encourage improvement
Create a sense of accomplishment

Characteristics of Good Tests
Validity – the extent to which the
test measures what it intends to
measure
Reliability – the consistency with
which a test measures what it is
supposed to measure
Usability – the test can be
administered with ease, clarity
and uniformity
Scorability – easy to score
Interpretability – test results can
be properly interpreted and is a
major basis in making sound
educational decisions
Economical – the test can be
reused without compromising the
validity and reliability
Other Things to Consider
“To be able to prepare a good
test, one has to have a
mastery of the subject
matter, knowledge of the
pupils to be tested, skill in
verbal expression and the
use of the different test
format”

General Steps in Test Construction
DRAFT
ORDER
TEST ANALYZE
SUBMISSION
PRODUCE A
T.O.S.
Table of Specifications (TOS)
A two way chart that relates the learning outcomes to the course content
It enables the teacher to prepare a test containing a representative sample of student behavior in each of the areas tested.
Sample TOS
KPUP Paradox
Knowledge – answers the question what, where and when (ano, saan at kailan)
Process – answers the question how? (paano)
Understanding – answers the question why (bakit)
Tips in Preparing the Table of Specifications (TOS)
Don’t make it overly detailed.
It's best to identify major ideas and skills
rather than specific details.
Use a cognitive taxonomy that is most
appropriate to your discipline.
Weigh the appropriateness of the distribution
of checks against the students' level, the
importance of the test, the amount of time
available.
General Rules in Writing Test
Questions
Number test questions continuously.
Keep your test question in each test group uniform.
Make your layout presentable.
Do not put too many test questions in one test group. T or F: 10 – 15 questions
Multiple Choice: max. of 30 questions
Matching type: 5 questions per test group
Others: 5 – 10 questions
Some additional guidelines to consider when writing items are described below:
1. Avoid humorous items. Classroom testing is
very important and humorous items may
cause students to either not take the exam
seriously, become confused or anxious.
2. Items should measure one’s knowledge of the
item context not their level of interest.
3. Write items to measure what students know,
not what they do not know. (Cohen & Wallack)
Multiple Choice Test
When checking the stems for correctness:
Ensure that the stem asks a clear
question.
Reading level is appropriate to the
students
The stem is grammatically correct.
Negatively stated stems are
discouraged.
What to Look for on
Multiple Choice Tests
Example:
What is the effect of releasing a ball in
positive gravity?
a) It will fall “down.” correct
b) It will retain its mass. true but unrelated
c) It will rise. false but related
d) Its shape will change. false and unrelated
Anatomy of a Perfect
Multiple Choice Tests
Multiple Choice Questions
1. Use negatively stated stems sparingly and
when using negatives such as NOT,
underline or bold the print.
2. Use none of the above and all of the above
sparingly, and when you do use them, don't
always make them the right answer.
3. Only one option should be correct or clearly
best.
Multiple Choice Questions:
4. All options should be homogenous and
nearly equal in length.
5. The stem (question) should contain only
one main idea.
6. Keep all options either singular or plural.
7. Have four or five responses per stem
(question).
Multiple Choice Questions:
7. When using incomplete statements place the blank space at the end.
8. When possible organize the responses.
9. Reduce wordiness.
10. When writing distracters, think of incorrect responses that students might make.
Examples
1. Sheldon developed a highly controversial theory of personality based on body type and temperament of the individual. Which of the following is a criticism of Sheldon's work?
a. He was influenced too much by the Freudian psychoanalysis.
b. His rating of physique and temperament were not independent.
c. He failed to use empirical approach.d. His research sample was improperly
selected.
Examples
Better: (Eliminate excessive wording and irrelevant information)
1. Which of the following is a criticism of Sheldon's theory of personality?
Examples
1. The receptors for the vestibular sense are located
a. in the fovea.b. in the brain.c. in the middle ear.d. in the inner ear.
Examples
Better: (Include in the stem any word(s) that might otherwise be repeated in each option.)
1. The receptors for the vestibular senses are located in the _______.
a. foveab. brainc. middle eard. inner ear
True or False
Each statement is clearly true or clearly false.
Trivial details should not make a statement false.
Statements are written concisely without more elaboration than necessary.
Statements are NOT quoted exactly from text.
What to Look for on
True/False Tests
Give emphasis on the use of quantitative terms than qualitative terms.Avoid using of specific determiners which usually gives a clue to the answer. False = all, always, never, every, none,
only True = generally, sometimes, usually,
maybe, often
Discourage the use of negative statements.Whenever a controversial statement is used, the authority should be quoted.Discourage the use of pattern for answers.
Tips in Making True/False Tests
Examples:
____ 1. Repetition always strengthens the tendency for a response to occur.
(Using "always" usually means the answer is false.)
Find the errors, and/or problems with the following true-false tests.
Examples:
_____ 2. The process of extinction is seldom immediate but extends over a number of trials.
(Words like "seldom" usually indicate a true statement.)
Examples:
_____ 3. The mean, median, and mode are measures of central tendency, whereas the standard deviation and range are measures of variability.
(Express a single idea in each statement.) e.g.“The mean and standard deviation are measures of central tendency.”
Matching Type

(Vertical Type)
Column A
(Premise)
Column B
(Response)
Parts of the Matching Type Test
(Horizontal Type)
(Response)
(Premise)
The list of responses should be relatively short.
Response options should be arranged alphabetically or numerically.
Directions clearly indicate the basis for matching.
Can responses be used more than once?
Where will you place your answer?
Can students infer relationships or are they based on real word logic?
What to Look for on
Matching Type Tests
Position of matches should be varied.
Avoid using patterns.
The choices of each matching set
should be on one page
There are more responses than
premises in a single set if responses
cannot be used more than once.
What to Look for on
Matching Type Tests
The premises are homogeneous as well as the responses and are grouped as one item.
Example: Set A: Provinces in Region I
Set B: Provinces in CAR
If responses can be used more than once, it should be proportional to the number of premises (3:5 or 4:10)
What to Look for on
Matching Type Tests
Examples:
Directions: Match the following.
1. Food A. Primary reinforcer
2. Psychoanalysis B. Sigmund Freud
3. B.F. Skinner C. Operant conditioning
4. Standard deviation D. Measure of variability
5. Schizophrenia E. Hallucinations
Examples:Better: (Use homogenous material in matching items, and if responses are not to be used more than once, include more responses than stimuli.)
Match the theories in Column A with their proponents in Column B. Write the letter of the correct answer.
Column A Column B
___ 1. Psychodynamic Theory A. Albert Bandura
___ 2. Trait Theory B. B.F. Skinner
___ 3. Behaviorism C. Carl Rogers
___ 4. Humanism D. Gordon Allport
___ 5. Social Learning Theory E. Karn Horney
F. Raymond Cattell
G. Sigmund Freud

Things to Remember:Making a good test takes time
Teachers have the obligation to provide their students with the best evaluation
Tests play an essential role in the life of the students, parents, teachers and other educators
Break any of the rules when you have a good reason for doing so! (emphasis mine)
(Mehrens, 1973)
POINTS TO PONDER…
A good lesson makes a good question
A good question makes a good content
A good content makes a good test
A good test makes a good grade
A good grade makes a good student
A good student makes a good COMMUNITY
