EFFECT OF TEST ITEM COMPROMISE AND TEST ITEM PRACTICE ON
VALIDITY OF ECONOMICS ACHIEVEMENT TEST SCORES AMONG SECONDARY SCHOOL STUDENTS IN CROSS RIVER STATE, NIGERIA.
Every examiner or individual using test scores should be confident that the
scores obtained by a test taker is a true indication of that person's level of
knowledge or ability on the construct of interest with a proper guide against
factors that can lead to score invalidity. However, this study determined the
effect of test item compromise and test item practice on Economics Achievement
Test Scores among secondary school students in Cross River State. It also
examined whether test item compromise and test item practice affected the
validity of test scores obtained in the Economics Achievement Test among
secondary school students in the state. A quasi-experimental research design
was adopted for the study. The population of the study consisted of all
secondary schools in the 18 Local Government Areas (LGA) of Cross River
State. The sample consisted of 90 SS2 Economics students randomly selected in
the three Secondary Schools used for the study which was carried out in an
intact classroom. There were three groups and 30 respondents were randomly
assigned to each group. The three groups were compromise group (E1),
practice group (E2) and control group (C1). The instrument used for the study
was an Economics Achievement Test (EAT) developed by Shogbesan (2017)
which consisted of 25 items of various formats with a liability index of 0.68. The
EAT was administered to the three groups with 13 items exposed as treatments
to E1 for the students to be familiar with some of the test items a few minutes
before the test, while the practice group was given the 13 test items to practice
with the help of the researchers and research assistants who are Economics
teachers in the school. The results indicated among others that students' scores
were inflated on compromised and practiced test items which contributed to the
score invalidity. It was recommended among others that security of test items
should be considered vital before and during test administration process.
