How to Develop a Pre/Post Test
- Define the focus of
the lesson being taught.
- Determine what key
ideas/concepts are being taught by the presenter.
- Brainstorm 10-15
possible questions that would effectively test the student’s
knowledge prior to the lesson and after the concepts have
been presented.
- Select a variety of
five questions (multiple choice, true/false,
fill-in-the-blank, etc.) that will peak the students
interest in excelling on the pre/post test and learning the
material being taught.
- Type the five
questions on an 8.5 x 11 page, taking note of the spacing
and organization of the page. Include an area for
designation of whether it is the pre or post test and for
the student’s name. You may add optional graphics that
relate to the focus of the lesson. (Please note: Do not
photocopy the pre/post tests on both sides of the page to
ensure result accuracy).
- Photocopy the pre/post tests (one of each for every student in the class being taught). Administer the tests before and after the lesson has been taught. Grade the pre/post test and calculate the percentage increase in knowledge.
SUCCESS!!!! You have now created a pre and post test!!
How to Calculate Perecent Increase in Knowledge
- Make sure you have
the legitimate answer key.
- Count and be sure
that you have an equal number of pre/post-tests.
- Grade all of the
tests. We prefer if you mark the missed questions with an X
and simply leave the questions answered correctly alone. Put
the number missed at the top of the page. Example: -3
- Multiply the total
number of students by the number of questions on the test
(usually 5) Example: 50 Students X 5 Questions = 250
possible questions
- Add the total number
missed for all the pre-tests. Example: -50
- Subtract that number
from your total listed in Step 4. Example: 250-50=200
- Divide the number
correct by the total number possible. Example: 200/250 = 80%
(This is an unusually high score for a pre-test)
- Repeat steps 5-7 for
the post-tests. Example: 250-10=240 240/250 = 96%
- Compute the increase in knowledge with the following formula:
(Post - Pre)/Pre = % increase in knowledge Example: (.96-.80)/.80 = .20 or 20%
