Developing computational thinking ability is crucial for those living in the 21st century. However, the current computational education system cannot satisfy this need. Current computational education tends to be limited to the teaching of the use of application programs or the teaching of the programming language. This is why the primary puzzle-based learning program was developed. This program promotes the development of the learner's computational thinking ability and understanding of the principles of the computer science as opposed to the fragmented, uniform programing education. In order to prove the effectiveness of this newly developed program, a 35-hour study was conducted to 41 students from grade 3 to 6 classrooms in Jeju Province. It was proved that this program brings positive changes in creativie problem-solving ability and problem-solving abilities in computer science. This paper is to provide the ground for the development of an educational program and to prove the effectiveness of thereof, and finally introduce the Primary Puzzle-Based Learning Program as the alternative computational education.

In this paper, we analyze the influence of mathematics teaching-learning for high level math problems of A-type of mathematics section on the College Scholastic Ability Test(CSAT). To analyze the influence, we compare and analyze units and field of questions set at examinations based on the rate of wrong answers in A-type mathematics test of the CSAT from 2012 to 2016. Also, we study the recognition of academic high school students and teachers about units and fields on math which need to allow more time to improve grade for A-type of mathematics section on the CSAT. We found following facts. First, high level math problems determining rank of high rank students on the CSAT was taken mostly from the unit related a exponential function and a logarithmic function. Second, these problems need more time for a calculation rather than an ability for students to deepen their understanding of the concept and quality of education. Third, high rank students spend a lot of time to study more important units and fields of mathematics on the CSAT such as a exponential function and a logarithmic function, and teachers spend a lot of time to teach them.

The purpose of this paper is to examine the concept of computational thinking in an easy-to-understand way for non-computer majors. First, It is necessary to expand from the problem-solving perspective to the perspective of problem discovery and creation ability, and establish it as a thinking ability that can cultivate human-like thinking, that is, creative thinking. Second, the concept of computational thinking can be viewed not only in the cognitive aspect but also in the emotional motive and attitude aspect. Third, systematic design of teaching methods is needed based on the expansion of the concept to computational thinking that helps learners to improve their reflective ability. It is expected that the results of this study will serve as basic research for various attempts in terms of the purpose and teaching method of computational thinking education in the future.

In a situation in which online classes were suddenly introduced due to COVID-19, there were many cases where learners did not properly learn science process skills that were not presented in the achievement standards for reasons such as reducing the number of class hours. It is difficult to expect positive science inquiry ability and science attitude from learners who have entered middle school without understanding the process skills. Therefore, in this study, the effect on science inquiry ability and science attitude was investigated by developing worksheets with enhanced process skills and applying it to learner-centered teaching linked online and offline. As a result, it was confirmed that there was a statistically significant positive difference between both. Based on this research, it is expected that students will pay attention to the process skills, which is the basis of science subjects, and continue to experience the process skills through learning-centered classes.

This study investigated the preservice and inservice elementary teachers' perceptions on professionalism of teaching profession, professionalism of science teaching, and their self-efficacy on science teaching. For this study, 64 sophomore, 53 senior preservice teachers and 23 elementary teachers who were also graduate students were participated. The questionnaires consisted of 5 Likert scaled and descriptive items about the professionalism of teaching profession, professionalism of science teaching, and self-efficacy on science teaching. The results showed that some areas of the professionalism of teaching profession had significant differences between the grades in preservice teachers and/or inservice teachers. Most preservice teachers and teachers thought that they need to have professional ability, but not a few teachers thought it was not necessary to have professionalism of science teaching as a elementary teacher, even though their major was science education. The teachers who had higher perceptions on the needs of the professionalism of science teaching showed high self-efficacy on science teaching.

The paper is about teaching culture in a language learning. There are many teachers who are afraid of teaching foreign language with culture. They are delighted to teach politics, economics, history, art and literature as objective culture. But they are hesitant to teach subjective culture which is connected with a communication competency. The paper suggests three stages to instruct culture in a schoolroom. The first stage, it is growing out of the self-centered view. The second step, be developing self-consciousness through comparing mother culture with target culture. The last stage, it has to response to appropriately target culture. The teaching materials for the model suggested are two movies. Because the cultural aspects in the moves are subjective culture, so it has something in common with target cultural situations in a language learning. This method which is teaching culture in a the language learning has the advantage of being easy to teachers and learners. Most students like to watch a movie. The teaching material is The Chronicles of Narnia : The Lion, the Witch and The Wardrobe와 Guess Who?. I hope that this suggestion for cultural teaching is helpful for understanding each other.
