It has been continually developed and revised to match our current understanding of how humans learn (American Psychological Association, 1997). It is based upon the belief that students should take responsibility for their own learning. Thus, curriculum, instruction, and assessment should be carefully designed to stimulate, facilitate, and accelerate students' learning as much as possible. In order to do so, the teacher needs to take the following factors into consideration: students’ cognitive structures, metacognitive and regulative skills, motivation and affective states, developmental and individual differences, and social supports. However, the term student-centered has been defined and described by researchers and scholars in many different ways. Little is known about how practicing teachers conceptualize this term and how they perceive their classroom practices in relation to these conceptions. The purpose of this study was to utilize a qualitative multiple-case study approach to investigate teachers’ conceptions of the student-centered approach and their perceptions of their classroom practices. Four Thai high school physics teachers, who were considered products of the current student-centered educational reform movement in Thailand, participated in this study. Data were collected for one learning unit (three to eight weeks) through classroom observations, semi-structured interviews, and document analysis. The data analysis revealed that teachers’ conceptions of student-centered curriculum, instruction, and assessment had three common characteristics: (a) students’ active participation; (b) special emphasis on students’ background knowledge, understanding, motivation, affective states, and learning capability; and (c) benefits to students. The results also indicated that there were some similarities and differences between teachers’ conceptions of the student-centered approach and the underlying principles of the student-centered approach. Moreover, this study showed that teachers’ conceptions of the student-centered approach were not always consistent with their classroom practices. In addition, these teachers used various instructional activities perceived by them as being non-student-centered, such as developing curriculum based on the national high school physics textbooks and teacher’s experiences, delivering knowledge through lecture, and assessing students’ understanding by using teacherconstructed test questions. Furthermore, findings from this study provide implications for researchers, teacher educators, and policy makers with regards to successfully implement the reform-based, student-centered approach in the actual science classroom
