This study was to explore the math teaching efficacy and perception for their own
math class of special class teachers. While subjects(n = 158) showed above-average
math teaching efficacy, there was no correlation between teaching efficacy belief and
outcome expectancy. The shorter subjects\' career was, the higher the outcome
expectancy was, and the longer subjects\' career was, the higher the teaching efficacy
belief was. And the more serious children\' disability was, the higher the teaching
efficacy belief was. The subjects who took a course on the math education at university
revealed higher mean on the math teaching efficacy. Teachers who had long career,
were in charge of children with serious disability, and took a course on the math
education perceived their own math class more positively. The higher teachers\' math
teaching efficacy was, the more positively teachers perceived their own math class. It
was also revealed that teachers had few opportunities to expand their competence on
the math education both in the past and in the present. Authentic pre- and in-service
teacher education positively influence on math teaching efficacy and math class itself.
Hence it is critical to discuss the system that promotes special teachers\' math teaching
efficacy by offering them actual chances to get pre- and in-service teacher education.
