The purpose of this study is to find out the level of science teaching efficacy belief in the elementary school teachers and to find out the students' science process skills and scientific attitudes according to the level of the teacher's science teaching efficacy belief. After measuring science teaching efficacy belief of 109 teachers from nine elementary schools, three teachers who received the high score and three teachers who received the low score were selected from each 5th and 6th grade. Science process skills and scientific attitudes of 331 students who were in the selected 12 teachers' classes were measured. The results of this study were as follows; First, there were significant differences on the elementary school teachers' science teaching efficacy belief according to teacher's gender and career. The men's average score was clearly higher than women's average score on personal science teaching efficacy in science teaching efficacy belief according to teacher's gender. There was a obvious difference between the group of more than six-year less than ten-year and the group of more than fifteen-year less than twenty-year, the group of more than twenty-year on science teaching outcome expectancy in science teaching efficacy belief according to teacher's career. Second, there was not a evident difference on the elementary school students' science process skill according to the level of the elementary school teachers' science teaching efficacy. Third, there was a distinct difference on the elementary school students' scientific attitude according to the elementary school teachers' science teaching efficacy. There was a significant difference on the openness and the endurance in each scientific attitude. The level of science teaching efficacy belief in the elementary school teachers had few effects on the elementary school students' science process skill, on the other hand the level of science teaching efficacy belief in the elementary school teachers had an positive effect on the elementary school students' scientific attitude.
