In a previous study with 130 undergraduate teacher candidates from all licensure levels, data on candidate effectiveness were examined using factor analysis. Four factors were found in effective teaching, those being lesson planning, teacher and student reflection, safe school environment, and teacher professionalism. The present study followed the 2012 one and was done to (1) determine whether the lesson planning factor was unitary or could be divided into any further factors, and (2) to identify subcomponents of lesson planning in terms of impact upon teaching effectiveness.
