The Thai government has strongly advocated for the learner-centered education for the past decade. Success For Life Thailand (SFLT), a brain-research-based early childhood education program blended with the theories of the developmentally appropriate practices and child-centered philosophies, has been implemented in Thailand for over 8 years. The purposes of the present study were to: (a) describe the current statuses of the Thai early childhood educators' learner-centered beliefs and practices, (b) identify if the SFLT training workshop affects teachers' learner-centered beliefs and practices, and (c) examine if other variables, along with familiarity with the SFLT program, predict teachers' learner-centered beliefs and practices. Ninety-three preschool and kindergarten teachers participated in the study. Among them, 17 were SFLT trainees in 1999 and 2000 (i.e., the previously trained group), 43 were trained in Year 2006 (the currently trained group), and the others were comparable to the currently trained group by matching the key personal and school variables. The Teachers Beliefs and Practices Survey: 3-5 Year Olds (Burts et al., 2000) and the Learner-Centered Education: the Assessment of Learner- Centered (ALCP) for K-3 (McCombs, 2001) were used to collect data on the various domains of the learner-centered beliefs and practices. Findings reveal that: (a) Thai teachers highly endorse learner-centered beliefs, (b) Thai educators demonstrate relatively low levels of developmentally appropriate practices and high levels of developmentally inappropriate practices (DIP) in comparing with the American early childhood educators, (c) the previously trained SFLT teachers score higher on the DAP domains and lower on the DIP domains than the other two groups, and (d) familiarity with the SFLT program, along with teacher's education level, years of teaching experience, and the total number of students in the classroom do not predict variations on the different domains of the DAP and learner-centered learning questionnaires. Future studies need to use indigenous measurement instruments appropriate to Thai education to evaluate the impacts of the SLFT program on teachers' learner-centered beliefs and practices when more trainees become available, and possibly to include other teacher, student, and school variables.
