The Goal of SW education is to cultivate creative and convergent human resources with computational thinking ability. The content and methods of SW education are diverse, and it is difficult for the students to properly evaluate what they have learned. In order to appropriately evaluate the learning contents, SW education evaluations should be able to easily evaluate the core content of the SW education. The purpose of this study is to provide a systematic framework that can be used to develop evaluation factors to evaluate the effectiveness of SW education in elementary and secondary schools. We conducted a literature review, a field suitability review through FGI, an expert consultation, and a Delphi survey. As a result, the metrics of the cognitive domain were developed with 17 keywords in three categories: Computational Materials & Outputs (CMO), Computational Concepts (CC), and Computational Practices (CP). Also, metrics of the affective domain were developed with 13 sub-areas in four categories: value, attitude, computational thinking efficacy, and interest. The SW education evaluation factors developed in this study can be used as a framework to develop the evaluation contents in accordance with the contents of education.

As SW education has become essential since 2018 due to the revised curriculum in 2015, researches on SW education are actively being carried out. In order to understand the level of pre-service teachers' computational thinking level, we analyzed a correlation of CT element scores with each year and each grade based on the calculated Scratch project by years using the analysis tool Dr. Scratch, which was targeted for 325 students in K National University of Education who passed the scratch course from 2016 to 2018. The result indicated that there is a positive correlation between all the CT related factors and both the year and the grade. Conclusionally, it is crucial to have students undergo revising process by using an automated evaluation tool such as Dr. Scratch and cultivate ability to create and utilize required materials. Furthermore, it is necessary to educate students to utilize logical thinking elements such as complex conditions and logic operations.

This study introduces a development of calculus contents which makes to understand the main concepts of calculus in a short period of time and to enhance problem solving and computational thinking for complex problems encountered in the real world for college freshmen with diverse backgrounds. As a concrete measure, we developed 'Teaching and Learning' contents and Python-based code for Calculus I and II which was used in actual classroom. In other words, the entire process of teaching and learning, action plan, and evaluation method for calculus class with Python based coding are reported and shared. In anytime and anywhere, our students were able to freely practice and effectively exercise calculus problems. By using the given code, students could gain meaningful understanding of calculus contents and were able to expand their computational thinking skills. In addition, we share a way that it motivated student activities, and evaluated students fairly based on data which they generated, but still instructor's work load is less than before. Therefore, it can be a teaching and learning model for college mathematics which shows a possibility to cover calculus concepts and computational thinking at once in a innovative way for the 21st century.

In this paper, we propose to discover the certification items and to study the content system for SW education instructors, including SW education based on basic teaching-learning capabilities and Computational Thinking(CT). To this end, SW education instructor qualification were divided into three classes using methods such as prior case studies, Delphi surveys, and expert meetings, and the certification evaluation areas were divided into large areas of 'Teaching and Learning Method' and 'Software Education' reflecting primary and secondary curriculum. Sub-areas and content elements for each series were set and verified through expert Delphi survey. Such research is expected to contribute to the spread and dissemination of SW education by being used meaningfully when establishing a system that fosters SW education instructors and maintains and manages the quality of instructors.

Modern society needs to think in new directions and solve problems by grafting problems from diverse fields with computers. Abstraction and automation of various problems using computing technology with your own ideas is called computational thinking. In this paper, we analyze how to diagnose and improve knowledge information based on computational thinking through the process of presenting a variety of problems in programming education situations and finding several problem-solving methods to solve them. To pretest the learners, they were diagnosed using a measurement sheet and a LightBot. By determining the correlation between the evaluation results and LightBot results, the learners' current knowledge statuses were checked, and the correlation between the evaluation results and the LightBot results, based on what was taught according to the problem-solving learning technique, was analyzed according to the proposed technique. The analysis of the group average score of the learners showed that the learning effect was significant. If the method of deriving and improving knowledge based on computational thinking ability for solving the problem proposed in this paper is applied to software education, it will induce student interest, thereby increasing the learning effect.

This study is a study on the coding mathematics curriculum that converges elementary and middle school mathematics and information subjects and a minimum coding game-based education method for this. For the past 3 years, the coding mathematics curriculum and educational methods to effectively operate the curriculum were studied by applying them to 6th graders of elementary school and 1st graders of middle school. As a result of the first year of research, the coding mathematics curriculum was modified to a coding environment including the mathematical concept of a three-dimensional coordinate space, and the three-dimensional object was improved to be output as a real 3D print. As a result of the 2nd year study, it was improved so that even low-level students can build buildings by introducing different level commands for each component of the building so that self-directed learning is possible. As a result of the 3rd year study, a teaching-learning strategy based on a minimal coding game was designed to induce an increase in the level of computational thinking, and evaluation and feedback for diagnosing computational thinking were developed. Educational methods to promote self-directed learning and computing thinking ability, and researched coding mathematics curriculum are meaningful for the research and practice of the convergence education of school mathematics and informatics.
