The purpose of this study is to develop a measurement scale for early childhood teachers with which the teachers may assess their level of pedagogical content knowledge in music, necessary for early childhood music education. The conclusions of this study are as follows: First, four elements-knowledge of curriculum, content knowledge, pedagogical knowledge, and knowledge of learner-and a total of 45 preliminary questions were devised. Second, suitability indices for the measurement scale for pedagogical content knowledge in early childhood music from the confirmatory factor analysis model were found to be x2 =275.250(d.=59), TLI=.943, CFI=.957, NFI=.946, RMSEA=.087( .077~ .097), which demonstrates that this measurement scale is a suitable model. To verify the concurrent validity of the measurement scaled developed in this study, a correlation analysis was performed with an evaluation tool for music teaching skill introduced in Park(2009). The result yielded correlation coefficient of .01, which is a statistically significant result. Third, The result showed high reliability coefficient. Consequently, the measurement scale developed in this study will be a helpful tool for early childhood teachers in improving their music classes.
