2Topics on Administering Analyzing TestsWhen
using them for important summative assessments
- Test administration
- Item analysis
- Cheating
3Fairness Real and Perceived
- Important that students perceive value in the
assessments - Motivated to do especially well on tests related
to - recorded grades, report cards
- passing or failing decisions
- Three attributes of perceived fairness
- Teach what you test.
- Broadly meant not just what you said in class.
- Give adequate notice.
- Pop quizzes are okay as long as you let students
know they are a possibility. - Be fair in grading.
- Consistent and reasonable.
- Fairness does not mean easy. Many students
appreciate high standards and a challenging test.

.Preparing Test Materials
- Give clear directions what, if any,
supplemental materials are permitted (scratch
paper, dictionaries, calculators). - Use a simple format use white space and
logical page breaks. - Allow lead time for copying dont race into
office and expect your test to be done right
away. - Spot check pages complete, in correct order,
not inverted. - Take one test and answer it non-fatal mistakes
you can correct with oral directions fatal means
recopy (dont postpone). - Worry about security keep secure may wish to
number copies. - Comparable forms for multi-section courses
students in later classes will ask students in
earlier sections about the test.

Preparing Yourself and the Students
- Assuming you have provided excellent content
instruction, recommended actions include - Give adequate notice to the students. This
includes the type(s) of items that will be found
on the test. - Schedule the test so that you have time
built-in when the test is completed for scoring
of the test. - Consider likely circumstances.
- Are there any special equipment needs?
- Is there anything scheduled that could be
disruptive (fire drill, pep rally)? - Should you pre-guide students as to what to do
if there is unanticipated commotion in the room
or building? (What to do with test documents.) - Make advance preparation for accommodations.
Accommodation is the technical term for
alterations in testing conditions related to
student disability. Specifically - An accommodation changes a condition (e.g.,
same test more time) - A modification changes the test itself (e.g.,
different test)
6Ohio Assessment Accommodations Criteria
established in Ohio Administrative Code Rule
3301-13-03
- To quote from the Accommodations statements found
on the Ohio Department of Education (ODE)
website Statewide Assessment Accommodations
include a list of common assessment
accommodations meant to help IEP teams make
appropriate decisions about allowable
accommodations for statewide assessment. It is
not an exhaustive list. Designations such as
"allowable" or "not allowable" for the test
subjects/grades and accommodations have been made
in light of the four allowable criteria for
statewide assessment accommodations explained at
the beginning of the list. - To quote from other parts of the ODE statement
specific to testing - Any accommodation that gives a student with
disabilities an unreasonable advantage is not
allowable, because it does not allow for valid
assumptions to be made from the results. - Accommodations are changes made in how a student
has access to the curriculum or demonstrates
learning. . . . In testing situations,
accommodations are changes in format, response,
environment, timing or scheduling that does not
alter in a significant way what the test measures
or the comparability of the scores.
7Suggestions, on the day of the test, for . . .
Immediate Preparation of Students
- Think about classroom seating arrangement
would rearranging be offensive how would you
rearrange (e.g. every other seat). - Determine how materials (e.g., test, answer
sheet) will be passed out (yourself passed front
to back) - check that everyone has all materials. - Establish control students often talk when
materials are passed about, decide when to
declare conversation time over. - Direct students to place names on answer sheet
and on test itself if this is important to you
for security reasons. This may suggest to
students that you look at any marks they make on
the test itself. - Review test directions some students skip the
written directions while others agonize too long
over them (should be no surprises). - Provide directions as to what the students do
when they finish their test (e.g., turn in, wait
quietly, study). - Give quick words of encouragement humor may
work or may backfire.
8Suggestions, once the test starts, for . . .
Managing the Testing Environment
- Monitor the testing situation dont use this
time as personal time to work on other classes
circulate around the room, help students stay on
task see if it appears someone is not correctly
following the directions (make sure you tell
students you will be doing this). When you do
sit, sit behind students out of their vision. - Answer questions with fairness in mind dont
give hints to individual students, clarification
only. If it appears what you might be telling
them is important, consider telling the entire
class. - Apprise students of remaining time if timing is
important or if there is no clock visible.
9Suggestions, once the test finishes, for . . .
Scoring and Returning Test Results
- Many teachers dislike this part it is time
consuming. The utility of having provided
yourself with a previously prepared scoring key
and time to score is key for success in this
area. I suggest you score exams yourself. - Return results promptly most often the sooner
the better. Getting results back quickly is good
for the mental health of students, and yourself! - Dont announce individual scores (although you
can publicly acknowledge a students outstanding
performance) dont post grades (legal issue will
be discussed later). You may make general
narrative statements (either positive or
negative) . . . I prefer positive (for example,
the class did well). - Reiterate the scoring system you used. Your
scoring approach should not be a surprise to the
students but, by restating it, you demonstrate
you tested them exactly as you said you would. - Decide how you want to deal with student
questions. Will you do over all items, some
items? What kinds of questions will you accept,
how long will the questions go on? Will you
change grades based on the discussions?
10Suggestions, once the test review finishes, for .
. . Retaining Test Results
- Recover materials as desired do this in such a
way that students do not see the scores of
others. Do you want all parts back? Can
students keep old tests for studying? If
collected, what will you do with them? - Record scores do this after you have gone over
test with students. Use grade book (hardcopy or
electronic). - Make notes - on changes you would like to make in
the assessment system when you teach this in the
future. Do this now while it is fresh in your
mind.
11Classroom Item Analysis . . .Examining the
quality of individual items p and D
statistics
- When the test is completed, we have two basic
questions - Was the difficulty of the item appropriate or was
it too hard or too easy? I can compute the item
difficulty index by dividing the number of
correct answers by total answers - p percent correct
- The higher the value the easier the item
- If the item was difficult, was this difficulty
okay? Does it discriminate between those who know
and those who dont? To answer this we compute
the item discrimination index. In this case we
look at each item in terms of did the students
who do the best on this test tend to get it right
more so than the students who did the worst. The
book divides the class in half (H L) I tend to
like thirds (H, M, L). Compare the percent
correct between H L groups - D H - L
- The higher the value, the more the item
discriminates . . . notice it go negative or
positive. Whats a or - mean?

table are percentagesof correct responses,
High/Low/Total Group
13Classroom Item Analysis, So What . . .
- Item analysis is important because a poor or bad
item may add to the unreliability of the test.
Why? Because if your purpose in the test was to
distinguish between those students who know the
material and those who do not, a bad item fails
to work toward this end (e.g., items answered
correctly by all, or items that no one answers
correctly.) - A rough "rule-of-thumb" is that if the item
difficulty is more than .75, it is an easy item
if the difficulty is below .25, it is a difficult
item. - It is my feeling that items with difficulties
less than 20 or more than 80 (especially if
they fail they discriminate) deserve your
attention. Such items should either be revised or
replaced. Perhaps you have a non-functioning
distracter. Perhaps your question misleads the
best students. An exception might be at the
beginning of a test where easier items (90 or
higher) may be desirable for initial confidence
building.
14Taking item analysis to the next level . . .
Item Analysis Programs
- If you get into item analysis on a large scale
(many students/items) consider - Independent vender computer software Test
Packages on test construction which often
include item analysis features. These may not be
good long term since the companies that produced
them come and go (no tech support). - The Test Development Software Package provided
by the publisher of the textbook you are using. - Test item analysis using the Microsoft Excel
spreadsheet program. - Your school district may have a centralized test
scoring service (usually limited to selected
response types of exams). This likely means that
you would need to require that your students use
a bubble sheet because it would be scanned. - These computer programs may use more complex
calculations for indices (aka, indexes) related
to item difficulty or discrimination but the
concept will be the same. For example, item
discrimination might be presented in terms of a
correlation coefficient (with a Greek letter or
an unusual sounding name, of course). Remember
how to interpret a correlation coefficient? The
scale is -1 to 1 so you would interpret it
much like the D statistic.
15Cheating
- Graphic from A Taxonomy of Text and Exam Fraud
by Dennis Maynes, 2008
16Say it aint so, Joe . . .Cheating and Academic
Integrity
- Most teachers would rather not discuss this
perhaps a form of denial. - Prevalence
- All levels of education
- Student View No big deal everybody does it.
- Practices
- Plagiarizing, especially Internet-based
- Cut and paste without attribution
- Other projects completed outside class
- Assistance from parents, siblings, family
friends, fellow students range from incidental to
complete authorship - Cheating on exams, tests (crib notes, look at
anothers test, pass notes) - Lets look at some cheating examples a major
source was - Gary K. Clabaugh Edward G. Rozycki, Preventing
Cheating and Plagiarism, 2nd Edition (2003)
Oreland, PA NewFoundations Press
17Taking note of crib notes . . .So called
because of how one cradles the small sheets.
- OLD SCHOOL
- Get into the classroom prior to test and write
crib notes on the desktop or the back rest of
seat in front. Variation, tape note folder on
underside of desktop. - Make sure the crib notes can be easily destroyed.
Example, chew gum during exam if a teacher
becomes suspicious eat the piece of paper. Do NOT
write on yourself, it is impossible to hide if a
teacher questions you. - Print off crib notes in size 6 font about 4 wide
by ½ long. Acquire transparent pen (BIC
recommended). Roll the paper around the tube of
ink and slide it in. - Remove label from a clear beverage, such as
Snapple. Put notes on the back of the label, then
paste it back in place using transparent glue.
During the exam take slow "thoughtful" swigs out
of the bottle. - Wear laced up shoes on the day of the exam (with
laces remove). Attach your crib notes behind
each tongue of the shoe. - NEW SCHOOL
- Crib notes on an electronic organizer a mini
tape recorder can be fitted with a tiny earphone
that can be hidden by combing hair over the ear
programmable calculators use of a cell phone in
a lavatory.
18Other Cheating Gambits . . .
- Signal answers among group. Keep an eye out for
the rearrangement of items on desktops, coded
body movements, and hand signals. - A student who has postponed a test or who takes
it in a later section, enlists a confederate to
smuggle an extra copy of the exam out of the exam
room. - Fraternity approach. Smuggle a copy of the test
from the room at the end of the test, note the
answer sequence when the test is reviewed then
keep both the test and the answers on file. - Student sits for the exam, pretends to be taking
the test, but completes nothing. Then they turn
in the blank exam and makes sure the instructor
notices it has been returned. When the tests are
graded and the student gets a zero because they
didn't take the test, he or she complains
bitterly that their test has been lost. - When tests are returned students either alter
their answers from wrong to right or fill in
answers they deliberately left blank. Then they
complained that their test was marked
incorrectly. - Students fake injury or illness to postpone tests
for which they are unprepared. - Students show up late, feign surprise and claim
that they misunderstood when the test was to be
given.
19Cheating Suggestions for Prevention
- Create positive classroom atmosphere - reasonable
standards, sensible workloads, keep content
interesting, keep upbeat attitude yourself. - Talk to students about cheating define cheating
behavior, identify consequences immediate/long
term. Is cheating rewarded in society? - Reduce anxiety and uncertainty - be clear and
informative about upcoming tests, what will be
tested, how. - Be vigilant consider changing seating, walk
among the students during testing. - When cheating occurs, confront it teachers
disregard of cheating is one reason students say
they feel so free to do it. - Determine if your school has a policy support it
- if the policy is nonfunctional, then help
develop new policy.
20Practical Advice
- Use summary checklists regarding each aspect of
test administration to remind you of
considerations at each phase you value. - Learn to do simple item analysis, use
occasionally. - Take cheating seriously.
