The purpose of the original study was to investigate practicum student teachers' reflectivity. This paper describes the use of a revised version of the Reflective Pedagogical Thinking Scale (Sparks-Langer, et al., 1990) to measure reflectivity. The original scale was used by the developers to assess reflectivity through a structured interview. The present study employs a revised version of the scale to assess reflectivity based on student teachers' weekly journal writings. The participants consisted of 223 student teachers from Batu Lintang Teachers College who were undergoing their first phase of their student teaching practicum of six weeks. Student teachers' practicum journals were collected at the end of the practicum and each participant's level of reflectivity was assessed through the use of the revised reflective pedagogical thinking rating scale. Results of the analyses indicate that student teachers were hardly reflective, exhibiting very low levels of reflectivity based on van Manen's classification of levels of reflectivity. Interpretations of the results and recommendations are discussed in relation to the context of the study. (Contains 2 tables.)
