The informatics in the 2015 revised national curriculum has established the identity as the core subject for the intelligent information society. However, while the nature, objective, scopes and contents, and achievement standards of the curriculum are systematic, there is a lack of research on effective teaching and learning, and assessment methods. This study analyzed the applicability of Bebras Challenge, which began in Lithuania in 2004 and has been attracting attention as a new informatics education model with 1.3 million students as participants in 2015 around the world. Furthermore this research presented related issues for the indigenization of Bebras Challenge. This study will be a basis for the research of teaching and learning, and assessment models as well as the spread of Bebras Challenge.

The 2015 revised national curriculum emphasizes software education according to national and social needs for the development of computational thinking. Therefore, it is necessary to analyze meaningful factors influencing the development of computational thinking ability, as well as researches on various teaching, learning and evaluation methods. The purpose of this study is to analyze secondary school students' computational thinking ability in the Bebras challenge 2017 tasks and the participants' results of the challenge, and to figure out the differences according to factors such as evaluation area, gender, and region. The results of this study are meaningful to understand the factors for the development of computational thinking and to suggest directions for the improvement of Bebras challenge as a evaluation tool for computational thinking ability.

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 evaluation of students' computational thinking begins with the evaluation of knowledge about the concepts and principles of computing. In this study, we analyzed the differences in teachers' perceptions depending on the description method of the bebras challenge questions to evaluate computer science knowledge. First, we classified the questions into two types depending on whether computer science terms were included or not. Also we made a computational thinking questionnaire with two types of questions and surveyed 72 major teachers. As a result, teachers expressed the opinion that the evaluation questions that revealed computer science terms were appropriate as evaluation questions for information subjects. They also perceived it as more helpful in assessing computational thinking and coding skills. Through the results of this study, we suggested that the way the questions are worded is important in the process of assessing students' understanding of computer science concepts and computational thinking skills.

The purpose of this study was to design a competence teaching-learning model that could help college students improve their computational thinking among core competences in SW education. A competence teaching-learning model, UDDPAAP (Unplugged-Demonstration-Decomposition-Pattern Recognition-Abstraction-Algorithm-Programming), was designed by analyzing competences of learners with no experience in software coding, by reconstructing DMM, DDD, and DPAA among the five existing SW-based teaching-learning models, and by analyzing unplugged activity and the Bebras challenge computational thinking scale carefully. The unplugged activity partially adapted to instruction for college students and some items chosen from the Bebras challenge computational thinking scale were applied to the existing teaching-learning model. To determine the effects of the study, pretest was conducted in freshmen for computational thinking and self-confidence on the basis of the experience in SW and computer information literacy education, and posttest following instruction applying the UDDPAAP teaching-learning model. The students provided with SW education based on the UDDPAAP teaching-learning model saw their computational thinking competence improved.

The purpose of this paper is to analyze the elementary school students' level of computational thinking ability by analyzing the domestic question and examination results of Beaver Challenge 2017. Based on the results of the 'Challenge' results of Beaver Challenge 2017, the achievement by element, gender, and grade of elementary school students II (elementary school 3.4) and group III (elementary school 5.6) Respectively. As a result of the analysis, the achievement by the evaluation factors showed difference within each group. In addition, there was no significant difference in achievement according to gender except for one area of group II. The achievement level of each grade was statistically significant in the group III. The results of this study are expected to provide implications for the level of students related to what can be evaluated in elementary school information education and contribute to the follow-up research.

Computer Science Unplugged activities are activities to learn about computer science through learning tools other than programming programs. Existing unplugged activities focus on the procedural thinking process and focus on guiding the thinking process through play. There is a lack of research on unsupervised learning, which plays an important role in machine learning, which has recently attracted attention. In this study, we designed and conducted an unplugged activities for unsupervised learning that analyzes data using video media familiar to elementary school students. The results on the effectiveness of the class were analyzed using the bebras challenge. As a result of analyzing the scores of the pre-test and post-test, it was confirmed that the students' computational thinking and problem-solving ability improved.
