In this paper, we adapted the frame by Lee et al (2013) to investigate to what extent the Korean mathematics textbooks for the 7th graders adapt the principles of Yungbokhap education. The analysis suggests that the textbooks mostly adapt the competence to use language, symbols and texts interactively, and to use knowledge and information interactively. Among the competencies for interacting in heterogeneous groups, the textbooks included the competences to related well to others and to cooperatively work in teams. The competence for acting autonomously was least adapted in the textbooks. The most tasks in the textbooks adapted the monodisciplinary integration and the personal contexts for integration. The results of this research show that Korean mathematics textbooks are limited in implementing the principal dimensions of Yungbokhap education. In the future development of mathematics textbooks, it is necessary to consider how to further reflect the various dimensions of Yungbokhap education to promote students' creativity and autonomy in mathematics class.

This study aims to inspect the effect of the yungbokhap education on the development of students' mathematical competence by analyzing students' mathematical discourse in math-based yungbokhap instruction designed by Moon(2014). Specifically, this research focused on the analysis of students' participation structure. The reuslts shows that the students' competence for mathematical communication and inquiry has been improved through the instruction. In particular, the students were increasingly engaged with consensual talk. Also, in the beginning stage, the students tended to unconditionally criticize for others' mathematical opinion. Through the class participation, they gradually developed the competence to express their mathematical ideas to their peers with reasonable mathematical bases. These results suggests that the mathematics-based yungbokhap instruction has positively contributed to the improvement of students' mathematical competence. Based on the results, this paper presented implications for mathematics-based yungbokhap instrcution.

This study is based on the perspective that tasks in local and global contexts are important to raise students' ability to mathematically analyze and solve diverse phenomena and social issues as members of future civil society. Therefore, this study analyzes 880 real world tasks from 13 types of 7th grade textbook based on 2009 revised Curriculum. As a result of analyzing tasks by using 3 types of context category and 9 types of ways as analysis framework and allowing repetitive coding, personal context was most frequent in the context of Younbokhap. In level of Integrated ways of Yungbokhap, sequential model in which other subjects' topics were not directly related to mathematics problem or presented in simple description is most frequent. The result shows that the textbooks are too limited to develop learner's competencies. Through such analysis result, we discuss about the necessity and methods of developing tasks which allow learners to study further in future society and global context and which connect other subjects' knowledge and social issue with mathematics in deeper level.
