The purpose of this study is to analyze the results of physics (optics) in nationwide standardized assessment and to investigate middle-school students' characteristics of achievement by using an option response rate distribution curve. For this purpose, we analyzed the 10 optics problems from the National Assessment of Educational Achievement (NAEA) items for middle school science subject conducted in 2010-2013. The results of this study are as follows; First, students showed a little higher achievement in optics than classical mechanics and electromagnetism. Second, students achieved significantly worse in 'formation of image' in 'light' part and 'variation of phase in propagation of wave' in 'wave' part. Third, students showed a context-dependent problem solving strategy and result. Additionally, we suggested some implications about the readjustment of some optics concepts level of national science curriculum, the need for teaching and learning strategies for basic level students, and the need for teaching and learning strategies focused on the realistic context.

In this study, in order to investigate the relationships between the self-efficacy, career maturity, and information subject achievement of information-specialized high school students according to information subject classes, their correlations were analyzed through a survey of 214 second and third year students enrolled in two information-specialized high schools in Seoul. The main results are as follows. First, in the analysis of differences in self-efficacy, career maturity, and information subject achievement according to demographic characteristics, there was no significant difference according to gender, grade, extracurricular or individual learning for information subjects. The more they recognized that their grades belonged to the upper group, the higher their sense of self-efficacy and information subject achievement were perceived, and the higher their career maturity. Second, the students' self-efficacy was analyzed to have a positive effect on their career maturity and information subject achievement. Finally, it was found that the students' career maturity had a positive effect on their information subject achievement. Based on the above results, we briefly present the development direction for the education system to improve students' self-efficacy, career maturity, and information subject achievement.
