Abstract
A strong tradition of research in developed countries has established consistent relationships between students' outcomes and their perceptions of psychosocial characteristics of the classroom learning environment. The present research provides a replication of the prior work in developed countries by using samples of students from two developing countries, namely, Indonesia and Thailand. Indonesian versions of the individualized Classroom Environment Questionnaire and the Classroom Environment Scale were responded to by 373 students in 18 Grade 8 and 9 classes in Padang, whereas a Thai version of the Learning Environment Inventory was responded to by 989 students in 31 Grade 12 classes in Bangkok or nearby provinces. Results supported the predictive validity of student perceptions in that significant relationships emerged between student outcomes and classroom climate among students in both Indonesia and Thailand.
