Developing an Instrument for Assessing Interest in Teaching STEM Content

摘要

An instruments created to assess perceptions of teaching Science, Technology, Engineering and Math (STEM) disciplines is analysed and found to have respectable to excellent internal consistency reliability, as well as good content, construct, and criterion-related validity for the areas assessed. Crobach's Alpha for the individual scale on the STEM Semantics Survey ranged from 0.629 to 0.982 across the constructs represented. These scores were judged to be acceptable to assess anticipated changes resulting from Middle anticipated changes resulting from teacher in-service activities, and are believed to be worthy of use by other STEM teaching projects.
