The aim of this longitudinal study was to examine prospective teachers’ mathematics
teaching efficacy belief during their enrollment in teacher education program and at the
end of their first year of teaching. In addition, the factors that enhance or inhibit
participants’ efficacy belief and how these factors affect their mathematics teaching
efficacy when they become inservice teacher were investigated. Mixed research design
was used in which data were collected through longitudinal survey and electronic
interviews. Findings revealed that prospective teachers’ mathematics teaching efficacy
beliefs increase during their enrollment in teacher education program but decrease
during their first year of teaching. In addition classroom management, communicating
with student, communicating with parents, mathematical knowledge for teaching,
material usage, and textbook usage are the factors that enhance or inhibit teachers’
efficacy beliefs during their first year of teaching.
