The purpose of this study was to analyze future student competency based elementary Korean language classes to examine how they can be combined with current classes based on achievement criterion. Focus Group Interviews (FGI) were conducted with elementary teachers to find current lesson plans and design strategies, and to analyze their perception of future student competency proposed by Ministry of Education. After competency based lesson design was combined with regular class and implemented, teachers were finally interviewed for feedback of the classes. This study found problem issues such as conception of core competencies, gap between student achievement and competency accomplishment, student evaluation system as well as administrative support for execution. This study concluded that teacher training and systematic support should be enforced to ensure teachers competencies before demanding strategically.

The purpose of this study is to develop students' creativity and artistic sensitivity by developing a convergence education program that links various subjects, including mathematics, science, and art based on design. Design is done in almost every human activity that pursues beauty and implements cultural value through patterns and images. We have developed three programs for elementary school students and two programs for middle school students, taking into consideration the achievement standards and curriculum content appropriate for the 2015 revised curriculum. It was assessed by a panel of five educational experts during the development and demonstration courses to evaluate the feasibility of the development program. The development program can enhance the design literacy and design sense of elementary and junior high school students and can be used convergent educational contents that can be applied in the free-semester system activities of junior high school. Through this program, adolescents who will lead the future design society will be able to acquire the sense of design, literacy, and design ability as design consumers and producers.

Current performance evaluation of the natural science section mainly focuses on teacher evaluation, which causes slow feedback on the evaluation result and little evaluation on colleagues due to limits of time and space. In addition, report performance evaluation, which is a main target of the evaluation in the natural science section, is conducted mostly based on records of experiments and observation without any systematic forms. Such performance evaluation cannot meet expectation on the evaluation for a self-adjustment through instant feedback on the evaluation result and improvement of motivation through sharing common performance standard. Therefore, the study here completes an experiment/research report through information sharing and discussion among colleague learners based on the web and uses it for colleague or teacher evaluation. In addition, it is intended to recognize needs of learners and develop a performance evaluation system that can provide learners with appropriate feedback through the result.

In 2009 revision and 2015 revision mathematics national curriculum, 'proof' was moved to high school from middle school in consideration of the cognitive development level of students, and 'proof by contradiction' was stated in the "success criteria of learning contents" of the first year high school subject while it had been not officially introduced in $7^{th}$ and 2007 revision national curriculum. Proof by contradiction is known that it induces a cognitive conflict due to the unique nature of rather assuming the opposite of the statement for proving it. In this article, based on the logical, mathematical and historical analysis of Proof by contradiction, we looked about the introductions and the applications of the current textbooks which had been revised recently, and searched for improvement measures from the viewpoint of discovery, explanation, and consilience. We suggested introducing Proof by contradiction after describing the discovery process earlier, separately but organically describing parts necessary to assume the opposite and parts not necessary, disclosing the relationships with proof by contrapositive, and using the viewpoint of consilience.

In the 2015 revised curriculum, software (SW) education was strengthened to cultivate computational thinking. In the curriculum of practical course at elementary school and of informatics course at secondary school, the characteristics, and content systems of SW education have developed systematically. However, it is necessary to study practical methods and cases for SW education because the curriculums provide only note and direction about teaching & learning, and evaluation methods for SW education. The purpose of this study is to analyze the achievement standards of the SW curriculum in the tasks of Bebras Challenge 2017 and to suggest various methods of teaching and learning, and of evaluation using the Bebras tasks. The results of this study are expected to propose a basis to develop various teaching and learning and evaluation researches.

The era of the Fourth Industrial Revolution calls for creativity - convergence talent. In addition to having mathematical knowledge, they can create new technologies by linking them to other fields. This social trend is also reflected in the 2015 revised curriculum, and plans to further expand the STEAM education emphasized since 2011. Many teachers who had previous experience with STEAM training were satisfied with the STEAM teaching effectiveness. However, the reality is that the lack of expertise in other subjects is causing a burden on the ongoing implementation of convergence education. One way to alleviate these teachers' burden is to find the STEAM elements and then apply. Since the convergence education is required continuously, it is necessary to analyze the textbook according to the 2015 curriculum. In this study, we examined how the elements of the STEAM were apply in 7th grade textbooks. Based on the classification framework proposed by Yakman (2008), a new classification framework was devised and applied to the analysis.

Although the multiplication of decimal fractions is expected to be easy for students to understand because of the similarity to natural numbers multiplication in computing methods, students show many errors in the multiplication of decimal fractions. This is a result of the instruction focused more on skill mastery than conceptual understanding. This study is a basic study for effectively developing a unit of multiplication of decimal fractions. For this purpose, we analyzed the curriculums' performance standards, significance in teaching-learning and evaluation, contents and methods for teaching multiplication of decimal fractions from the 7th curriculum to the revised curriculum of 2015 and the textbooks' activities and lessons. Further, we analyzed preceding studies and introductory books to suggest effective directions for developing teaching unit. As a result of the analysis, three implications were obtained: First, a meaningful instruction for estimation is needed. Second, it is necessary to present a visual model suitable for understanding the meaning of decimal multiplication. Third, the process of formalizing an algorithms for multiplying decimal fractions needs to be diversified.
