ASSESSING AND VALIDATING SCALE INSTRUMENT FOR MATHEMATICS TEACHERS

Edmundo C. Lopez

Abstract


This study developed and validated scale instrument for mathematics teachers, which can be used for an initial step in recruiting competent mathematics teachers. The scale items were developed by intensive and extensive reading, and soliciting ideas from students, teachers, and school administrators about their perceptions on competent mathematics teachers. The scale items were finalized and subjected to three try-outs to establish their reliability and validity. The SPSS version 14.0 was used to analyze the gathered data. Results showed that the scale items were valid and reliable at 0.987 Cronbach’s alpha; hence, this developed and validated scale instrument served its purpose.
