Homework Approach Scale for Middle School Students Tests of Measurement Invariance and Latent Mean Differences

This investigation assessed the psychometric properties of the Homework Approach Scale (HAS) using 1,072 students in Grades 7 and 8. Having randomly divided the sample (n = 1,072) into two subsamples, we conducted exploratory factor analysis (EFA) on subsample 1 and confirmatory factor analysis (CFA) on subsample 2. Factorial results indicated that the HAS contained two factors: Deep Approach and Surface Approach. Provided with sufficient measurement invariance, the factor means were tested across gender and grade levels. Males scored significantly lower in Deep Approach yet higher in the Surface Approach. There were nonsignificant differences in Deep Approach and Surface Approach across the grade level. Congruent with theoretical predictions, homework completion and mathematics achievement were related positively to Deep Approach and negatively to Surface Approach. This investigation offers robust evidence that the HAS is a valid measure for assessing students' approaches to homework.
