This article reports a study of secondary students' perceptions of mathematics classroom learning environment and their associations with their motivation towards mathematics. A sample of 81 students (19 male and 62 female) in two schools were used. Student perceptions of the classroom environment were assessed using a modified What Is Happening In this Class? (WIHIC) questionnaire. Associations between student perceptions of the learning environment and motivation towards mathematics were examined using simple correlation and multiple regression analyses. The results of the t tests for independent samples indicated a statistically significant difference in student perceptions between different school types. Student perceptions on some of the modified WIHIC scales were statistically significantly associated with student motivation. The results suggest that teachers wishing to improve student motivation towards mathematics, in general, should emphasise the learning environment dimensions that are assessed by the WIHIC. The findings have implications for teachers of mathematics and head teachers, particularly those in secondary schools.
