The CAI (Computer-Assisted Instruction) system for science teaching has been increasing both in quantity and in quality during the last two decades. However, science learning by computer has not played a leading role in the science teaching process. Therefore, the purpose of this study was to analyze the effectiveness of tutorial CAI programs according to the learner's characteristics such as sex, inquiry skills, attitudes toward science subject, logical thinking skills, achievement motivation, science content achievement in science teaching. One group pretest-posttest design was used as an experimental design. The three tutorial science CAI programs were used for thirty males and females selected in grade eight. According to the analysis of CAI achievement scores the female students showed significantly higher (P<0.05) than the male students. Also, one-way analysis of variance was used to investigate the effects of interaction between sex and achievement motivation. The significant difference on the effects of interaction between sex and achievement motivation has not found. The effects of tutorial CAI between logical thinking skills, attitudes toward science subject, inquiry skills, achievement motivation, science content achievement according to upper and lower levels were investigated by using the statistical analysis of one-way ANOVA. The results indicate that tutorial CAI might provides a good opportunities for the improvement of science achievement to the lower level students of attitudes toward science subject, inquiry skills, science content achievement.

The Science Writing Heuristic (SWH) approach is described as an immersive argument-based science inquiry focusing particularly on learning through epistemic practices. In the literature, several previous studies indicate how academic achievement is positively influenced by the SWH. In addition to these previous studies, several meta-syntheses of qualitative data have been conducted on this particular topic. With these literatures in mind, a quantitative meta-analysis was conducted with ten studies (N = 724) to examine the effectiveness of the SWH on student achievement in Turkey. To present a thoroughly detailed report, this study also examined the following moderators: grade level, subject area, school location, intervention length, and report source. Overall, this study found that in Turkey, the SWH classrooms performed better in academic achievement tests than traditional lecture-based classrooms. Additionally, the SWH is more likely to be effective regardless of grade levels, subject areas, and school locations.

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.

Recently in South Korea, various methods are followed in decreasing educational gap between region and social classes through school education. The National Assessment Educational Achievement(NAEA) intends to strengthen responsibility of school education and manage quality of curriculum. Besides, the NAEA intends to bridge achievement gap which is one of educational gaps by grasping the characteristics of academic ability to guarantee basic academic ability. There is not much research about the educational gap among regional scales. Therefore in this study, to examine the achievement characteristics among regional scales closely, we analyse the 2010, 2011 NAEA results in elementary mathematics subject and explore characteristics of items which have sharp differences between local population sizes. The results of the analysis has been showed that the educational gap between 'big-sized cities' and 'small and midium-sized cities' has been increased, but the overall educational gap among regional scales has been decreased.

For effective teaching-learning activities for students with diverse talents in science high schools, it is important for teachers to understand students' individual differences in perceiving and processing information in the natural world, depending on the students' various talents and subject characteristics. The purpose of this study is to examine the students' cognition of chemistry in science high school through correlations and factor analysis of mathematics/science achievement. In addition, this study attempted to examine the cognition of chemistry subject according to R&E classes. The main participants of the study were freshmen of G science high school (296 students) who entered after three times of curriculum reforms and new admission processes and the students in two other science high schools in Gyeongnam and Ulsan were included. The correlation and factor analysis were conducted by exploratory factor analysis by IBM SPSS Statistics 25 programs. The results of this study were as follows: First, in the correlation analysis between mathematics and science achievement, it was confirmed that the Pearson's coefficient of chemistry showed higher positive correlation coefficient than that of other science subjects. Second, in the factor analysis of mathematics and science achievements, it was found that the factor indicators were divided into two factors as logical-mathematical (mathematics and physics) and naturalistic (life science and earth science). Third, in the factor analysis, it was confirmed that the chemistry is recognized as the subject that requires both logical-mathematical and naturalistic intelligence. Finally, it was confirmed that students' cognitions of chemistry subject were found to differ according to the R&E classes. In other words, the participants of R&E chemistry class, unlike other students, were found to recognize chemistry as the subject that logical-mathematical intelligence is needed.
