Abstract
The aims of this study were investigated data analyses which provide information of the Individualized Classroom Environment Questionnaire (ICEQ) composes with Personalization, Participation, Independence, Investigation, and Differentiation scales was used, relationships between student’sscience attitudes and actual perceptions of chemistry classroom individualization were associated. The sample size data from 188 upper secondary school students in Roi-Et Wittayalai School on the ICEQ were analyzed using multilevel variance components models to derive intra-class correlations to determine the degree to which ICEQ scores may validly be said to measure aspects of classroom climate as against individual student’s attitude with the Test Of Chemistry-Related Attitude (TOCRA). The results showed that the class variable accounted for large and noteworthy proportions of overall variance in all five ICEQ scales. Subsequent analyses showed that statistically significant proportions of variance were attributable to the school variable. Suggestions that the ICEQ may be considered to be a relatively good measure of chemistry classroom environment are provided. The multiple correlation R was significant for the Actual Form of the ICEQ and showed that when the five scales are considered together there was significant (ρ < 0.05) association with the TOCRA, the R2 value indicates that 34% of the variance in students’ attitude to their physics class was attributable to their perceptions of their individual classroom learning environment in physics classes. In these terms, the ICEQ may be considered to be a relatively good measure of classroom climate.
