Authenticating Factor Analysis of Attitude towards Mathematics Inventory (ATMI) in Thailand
The study examine the psychometric properties of Attitudes towards Mathematics Inventory (ATMI) in the Thai context. To achieve the objective set by the authors, 259 students from 10 different primary schools in Nakhon Si Thammarat province, Thailand were selected. Furthermore, a forty items ATMI questionnaire having four scales that is, 15 items measuring self-confidence, 10 items measuring value, 10 items measuring enjoyment, and 5 items measuring motivation from the study of Khine and Afari (2014) was adapted. The questionnaire adapted was translated to Thai language by expert English Thai lecturer. Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy and Bartlett’s test of sphericity were carried out to ascertain the factorability of the correlation matrix. That ATMI can be a viable scale to measure students’ attitudes toward mathematics in Thai context.
