This study aims at grasping whether or not the U-mentoring for teaching practice is related to
self-conception of prospective infant teachers and teacher efficacy. To this end, out of fourth-year
students of the Early Childhood Education Department of N University located in G City, I set 13
students as an experimental group and the other 13 students as a comparative group. And I applied
the U-mentoring teaching practice guidance method to the experimental group during the four-week
teaching practice. After measuring the self-conception and teacher efficacy of the experimental group
and the comparative group before and after the teaching practice, I compared the difference between
before and after through analysis of covariance (ANCOVA). Based on the study result, firstly, in
terms of the self-conception of prospective infant teachers, the post score increased meaningfully
compared with the pre score after U-mentoring for teaching practice in self-acceptance, the
subordinate scope of self-conception. Secondly, in terms of teacher efficacy of prospective infant
teachers, the teacher efficacy score meaningfully increased generally after U-mentoring for teaching
practice. Such a result means that U-mentoring for teaching practice meaningfully affects the
self-conception of prospective infant teachers and improvement of teacher efficacy. It indicates the
necessity of U-mentoring application as a method to enhance the self-conception of prospective infant
teachers and teacher efficacy in the future teaching practice process.
