Abstract
This study examined the psychometric properties and measurement invariance of the Arabic version of My Class Activities (MCA), an instrument designed to measure students' perceptions of interest, challenge, choice, and enjoyment in classrooms. Scores of 3,516 Sudanese students in Grades 2 to 8 were used. Confirmatory factor analysis (CFA) was used to evaluate the factor structure of MCA. Multigroup CFA was used to examine measurement invariance across students in gifted and regular schools (nongifted). Four items were deleted to improve model fit and internal consistency. Results indicated noninvariant indicator intercepts across gifted and nongifted students, suggesting that MCA-Arabic can be used with elementary and middle school students; however, it should not be used to compare gifted and nongifted students.
