Since 2019, the informatics education is being conducted for elementary school 5th, 6th grade students through the curriculum revised 2015. But, informatics education is implemented from the lower grades of elementary school in many countries. The purpose of this study was to suggest the direction in the choice of programming language considering characteristics for lower grades student. In order to achieve the goal, evaluation criteria were developed considering the development characteristics of lower grades and necessary elements of educational programming language. The results of analyzing the usability of the two languages based on the criterion are as follows. First, Viscuit can be used to consider the expressive power of students with lower school age or to learn algorithms without learning about programming concepts. Second, ScratchJr is easy to learn the concept of algorithm and programming. This study is meaningful in that has presented implications considering the developmental state of the students in preparation for rhe programming education.

초등 교육과정에 소프트웨어 교육 내용이 포함되는 2015 개정 교육과정의 시행을 앞두고, 학교 현장의 교사들은 이에 대한 지도 준비 수준이 낮으며 소프트웨어 교육 관련 교수 학습 자료도 부족하다고 느끼고 있었다. 이에 본 논문에서는 체험을 주 내용으로 하는 초등학교 프로그래밍 영역에 활용이 가능한 웹캠 기반 스크래치 프로그래밍 교육 콘텐츠를 개발하였다. 이 때 프로그래밍 흥미를 높일 수 있는 방법으로 웹캠을 사용하여 사용자의 움직임과 상호작용이 가능한 콘텐츠를 제작하였으며 총 10차시로 구성하였다. 추후 본 논문에서 제안한 교육 콘텐츠를 초등학생들에게 적용하여 교육적 효과를 검토할 것이다.

텍스트 기반 언어 스몰베이직은 적은 수의 언어 특징을 가지고 있어 배우기 쉽고 이후에 C/C++/Java로 빠르게 전환할 수 있기 때문에 청소년 코딩 교육용 언어로 적합하다. 코딩 교육에 흥미를 높이기 위해 다양한 라이브러리가 필요한데 마이크로소프트에서 개발한 스몰베이직 환경에서는 로봇 프로그래밍을 위한 라이브러리를 지원하지 않는다. 이 논문에서 오픈소스 소프트웨어 스몰베이직 환경하에 동작하는 햄스터 로봇 라이브러리를 설계 및 구현하였다. 교육용 언어 스크래치와 파이썬에서 유사한 로봇 프로그래밍 라이브러리를 지원하지만 스크래치는 그림 기반 언어이기 때문에 이후 C/C++/Java로 전환하기 어렵고, 파이썬은 객체와 클래스 개념을 포함하고 잇어서 초보자가 배우기 어렵다. 이 논문에서 개발한 라이브러리를 활용하여 데모 프로그램을 작성함으로써 쉽게 스몰베이직 기반 로봇 프로그래밍을 할 수 있을을 확인하였다.

The purpose of this study is to analyze the experience of the process of developing instructional media by using Scratch for in-service teachers, after they participated in programming education with Scratch conducted as part of teaching methods using ICT. In particular, this study aimed to explore in-service teachers' thoughts and experiences of the objectives and methods integrated the programming education into their subjects creatively and convergently. To achieve the objective, they conducted an instructional design in accordance with their subject's learning goals and methods on the framework of the ASSURE model. Then, they conducted a project to develop instructional media with Scratch as part of the instructional design. 10 in-service teachers who attends the Graduate School of Education at K University in the second semester of 2019 were participated in this study. As a result, teachers showed positive expectation that the use of media developed by Scratch could bring significant results to attract students' interest and promote students' participation to lead learner-centered classes. This study has implications for future direction on programming education for professional development programs of prospective teachers as well as in-service teachers.

In the knowledge-information-oriented society, it is difficult for students to solve lots of problems or adapt themselves to society just by using simple knowledge. Students have to develop individual problem solving ability and creative, logical thinking ability. They can develope these abilities by learning computer programming. This thesis studies the influences of a flow-chart learning on the logical thinking ability in Scratch using programming learning. The findings identify that the making algorithm by using flow-chart is more effective in developing logical thinking ability then the making algorithm by using pseudo-code.

Previous studies on educational programming language reported that programming education can help students develop their abilities in cognitive, logical and reflecting thinking for problem solving. In this study, we examined the effects of Scratch programming language education on self-directed learning ability through six-grade elementary school students. The study results are that the treatment group shows more improvement with statistical significance on the subscales of self-directed learning such as openness, internal motivation, and autonomy, than the control group. These effects are especially larger with the students with high ICT literacy, whose degree is higher than that as a result of using digital textbook, UCC, and cyber home education reported in previous studies.

Recently, the discussion of domain-generality vs. domain-specificity of creativity has been continued. At this point in time, we need to research computer programming activities related to creativity again. While most of existing relative researches have performed TTCT figural tests for evaluating learners' creativity of learning education programming language, our perspective is that verbal creativity is needed on learning education programming language more. In this research, we have developed scratch programming learning based on CPS with the contents using fundamental concepts of computer science from the viewpoint of that programming is a kind of learning required verbal thinking style. This learning program was applied to 17 students of 4th and 5th grade for each 4 classes in 5 days, total 20 classes, this group passed normality test has the result of t-test has found that three subscales (fluency, flexibility and originality) and creativity index (mean of three standard scores) of verbal creativity were improved significantly using the mean of standard scores (100) of TTCT verbal tests as the test value.

In order to analyze the change of student's logical thinking, in this study, we were develop the educational materials. This educational materials were used in algorithm class through educational programming language Scratch. Algorithms of education materials were selected by analysis of foreign ACM and domestic middle school curriculum. The developed educational materials were applied to 4th grade students of elementary school. In order to analyze the change of student's logical thinking, we were used GALT short version. Total logic and Combinational reasoning, in the experimental group students, were growing significantly.

Nowadays it is required for a student to have the ability to select right things in quantity of knowledge and constructing those in the right way for the individual. Because memorizing a little bit of everything doesn't allow a person to work up to their potential and be the person society wants. In the basis on the revised Information and Communications Technology guidelines at elementary and middle school, it is demanded to start education in elementary schools. Meanwhile elementary school students usually feel bored or find it difficult in learing through the existing program. So I will plan the lesson by Scratch program for programming education and see the effect of this after using that method.

This research was performed of high school science classes. These science classes progressed by using Scratch, and surveyed students' perception after finishing each class. This research was conducted of male students who want to choose department of natural science in the next grade. Those classes are consisted of four classes. This study produced a journal, and contained expressions of their thinking and feeling based on experiences during attending classes and projects. Consequently, that journal was analyzed in view of understanding and perception of Scratch using science classes, and it was also included of utilizing Scratch program. Research shows following three conclusions. First, students preferred Scratch using class to general one. They attend more active with high interest, and they felt senses of accomplishment while they make output by themselves. Second, their studies passed through three stages. These are problem perception, problem solving, and producing. Problem solving stage is especially complicated and difficult stage to students. This stage is consisted of Scratch side and Science side. Scratch side has Design and applying process, and Science side has data gathering and analyzing. Students' comprehension of scientific knowledge is increased and is preserved long time through this stage. Last, students had a hard time using Scratch. Because, it is the first time to them to use that program. Therefore, we deemed that they needed to start this kind of experience at lower grade than they are now, such as middle school stage. It is expected that this type of classes are getting more expanded and more populated as a part of students' core ability.
