Psychometric Properties OF THE Wechsler Intelligence Scale-Iv Arithmetic Test FOR Elementary School Students IN THE Kingdom OF Saudi Arabia

Abstract

This study aimed to identify the psychometric properties of the arithmetic test of the Wechsler Intelligence Scale-4 among primary school students in the Kingdom of Saudi Arabia. The study sample included (50) primary school students, aged (6-12) years, from schools in the Eastern Province of the Kingdom of Saudi Arabia. The sample was selected intentionally, and the (arithmetic) subtest of the Wechsler Intelligence Scale-4 was applied.

The results showed that the validity indications represented by Content Validity were (80%), construct validity (α = 0.01, and α = 0.05), and the factorial validity indications among students were between (0.410 - 0.918), and the factorial analysis validity indications were (100%) of the variance in the total score of the test, and the discriminant validity indications according to gender reached the value of the statistic (T) (2.610) in favor of males, and the discriminant validity indications according to age reached the value of the statistic (T) (3.580) in favor of the student group aged (6-8 years).
The results showed that the Reliability implications represented by the internal scale Reliability implications of the Cronbach Alpha test = (0.791), and the Reliability implications of the split-half Cronbach Alpha reliability coefficient for the first part were (0.776) and the second part were (0.852). The value of the correlation coefficient between the first and second parts was (0.692) and the value of the Reliability coefficient split-half using the Guttman Split-Half Coefficient test was (0.815).
The study recommends conducting more studies and research related to conducting studies related to the impact of both verbal intelligence and mathematical problem-solving skills and working on developing the solution steps for students.
