The purpose of this study is to reveal the predictors of self-efficacy levels of primary school teacher candidates'for developing verbal, reading and writing skills in terms of their self-efficacy levels for applicating constructivist approach and their teaching motivations. The study is designed as a quantitative correlational survey research. The sample of the study consists of 374 primary school teacher candidates who enrolled at three different state universities' department of primary education in the faculty of education. Data regarding the predictors of self-efficacy levels of primary school teacher candidates'for developing verbal, reading and writing skills interms of their self-efficacies for implementating constructivist approach and their teaching motivations were gathered using Verbal skills Development Teacher Self-efficacy Scale, Reading Skills Development Teacher Self-efficacy Scale, Writing Skills Development Teacher Self-efficacy Scale, "Self Efficacy Perceptions of Teachers about the Implementation of the Constructivist Approach Scale, and Motivation to Teach Scale. According to the findings, it was concluded that the self-efficacy of primary school teacher candidates for developing verbal, reading and writing skills differed significantly according to gender, the self-efficacy of primary school teacher candidates'for developing verbal and writing skills did not differ according to their universities. However, for their self-efficacy for developing reading skills, teacher candidates who enrolled at University A statistically significantly differed from the teacher candidates who enrolled at University B, the self-efficacy of primary school teacher candidates'for developing verbal, reading and writing skills significantly differed according to their self-efficaciy for applicating constructivist approach, there was a significant correlation between the self-efficacy of primary school teacher candidates'for developing verbal, reading and writing skills and their self-efficacy for applicating the constructivist approach, there was a significant correlation between the self-efficacy of primary school teacher candidates'for developing verbal, reading and writing skills and their teaching motivations. The self-efficacy of primary school teacher candidates' constructivist approach application predicted significantly of their self-efficacy for * Bu çalışma Ebru Yuvanç (2019)'ın Ayşe Nur Kutluca Canbulat danışmanlığında hazırlamış olduğu yüksek lisans tezinden üretilmiştir.
