Recently in major industrial areas, there has been a rapidly increasing demand for 'Computational Thinking', which is integrated with a computer's ability to think as a human world. Developed countries in the last 20 years naturally have been improving students' computational thinking as a way to solve math problems with CAS in the areas of mathematical reasoning, problem solving and communication. Also, textbooks reflected in the 2009 curriculum contain the applications of various CAS tools and focus on the improvement of 'Computational Thinking'. In this paper, we analyze the cases of mathematics education based on 'Computational Thinking' and discuss the mathematical content that uses the CAS tools including Sage for improving 'Computational Thinking'. Also, we show examples of programs based on 'Computational Thinking' for teaching Calculus in university.

Computing thinking is regarded as one of the important skills required in the 21st century, and many countries have introduced and implemented computing thinking training courses. Among computational thinking education methods, educational game-based methods increase student participation and motivation, and increase access to computational thinking. Autothinking is an educational game developed for the purpose of providing computational thinking education to learners. It is an adaptive system that dynamically provides feedback to learners and automatically adjusts the difficulty according to the learner's computational thinking ability. However, because the game was designed based on rules, it cannot intelligently consider the computational thinking of learners or give feedback. In this study, game data collected through Autothikning is introduced, and game score prediction that reflects computational thinking is performed in order to increase the adaptability of the game by using it. To solve this problem, a comparative study was conducted on linear regression, decision tree, random forest, and support vector machine algorithms, which are most commonly used in regression problems. As a result of the study, the linear regression method showed the best performance in predicting game scores.

Seven textbooks for children used in homes and schools (sudangs) of the Chosun dynasty were examined to investigate how they taught emotional intelligence in traditional Korean society. The contents of the books were analyzed according to the 4 abilities of emotional intelligence described by Salovey and Mayer (1966): (1) perception, appraisal, and expression of emotion, (2) emotion's facilitation of thinking, (3) understanding and analyzing emotions, and (4) regulation of emotion to promote emotional and intellectual growth. The analysis showed that most of the books valued emotional intelligence and taught children how they perceive, appraise, and express emotions. The emotional ability to facilitate thinking was also emphasized, whereas the ability to understand and analyze emotions was seldom mentioned. It was also found that the regulation of emotion was emphasized; that is, children were educated to control and depress their emotions rather than to express them naturally.
