This paper presents evidence for the development
and validation of an “Achievement Test on Body Systems” which is a unit in 7th
class Science Education lesson. The test was conforming the acquisitions
described in the Turkish National Science Education Program for 3, 4, 5, 6, 7
and 8th classes. At the same time, number of the acquisitions, step of the
acquisitions according to Bloom's taxonomy, number of lessons to finish all
units and formerly learned concepts were taken into account for creating items.
The content validity of the test was reviewed and ensured by 1 expert and 2
science teachers. One of the teachers was doing her PhD degree and one of them
was doing his master’s degree. The pilot test was made up of 48 items selected
from initial 78 items and the sample consisted of 245 7th grade students.
Kaiser-Meyer-Olkin Test (which is a measure of how suitable the data are for
Factor Analysis) was done. Kaiser-Meyer-Olkin value was 0.89, and the result
indicated that the sampling was adequate. Analyses based on classical test
theory used 33% of the upper and lower classes for item difficulty and
discrimination indices. And the KR-20 was used for the reliability. After
omitting 3 items; the item difficulties were between 0.36 and 0.81, the item
discrimination indices were between 0.40 and 0.89 and the internal consistency
of the test (KR-20) was found as 0.898. Results indicate that Achievement Test
of Body Systems has satisfactory psychometric properties and it can be accepted
as appropriate for future use.
