Classroom Observation of Early Mathematics - Environment and Teaching (COEMET)

COEMET is a classroom observation instrument that evaluates classroom culture and the use of specific math activities. It includes questions about how actively the teacher interacts with the children, how the teacher uses teachable math moments, how math is displayed in the physical environment of the room, how confident the teacher appears about math, etc. The specific math activities measured are not connected to a specific curriculum.

Psychometric Considerations

Psychometrics is the science of psychological assessment. A primary goal of EdInstruments is to provide information on crucial psychometric topics including Validity and Reliability – essential concepts of evaluation, which indicate how well an instrument measures a construct - as well as additional properties that are worthy of consideration when selecting an instrument of measurement.
