매일매일 넘쳐나는 방대한 양의 정보와 지식들을 학생들에게 모두 가르치기란 매우 어려운 일일뿐더러 사실 불가능한 일이라 할 수 있다. 따라서, 낱낱의 지식을 알려주기보단 학생이 처한 문제 상황에 능동적으로 대처해 나갈 수 있도록 문제해결력을 신장시켜주는 것이 매우 중요하다. 이러한 문제해결력을 신장시켜주기 위해 프로그래밍 교육은 매우 긍정적인 역할을 하고 있다. 따라서 정보통신기술교육 운영지침의 3단계에 근거하여 초등학교에서 꼭 학습해야할 프로그래밍의 기초 개념이나 규칙 등을 학습할 수 있도록 DiKi 학습프로그램을 설계하여 실험집단에게 적용하였고, 통제집단은 정보생활 교과서를 활용한 정보처리 영역의 프로그래밍 관련 학습을 진행하였다

The modern softwares have features of modularity and extensibility, and there are several researches on extensible programming languages and compilers. In this paper, we introduce Argos programming language, which provides the extensibility with the concept of plugin languages. A plugin language is used to define a method of a class, and the plugin language processors can be added and replaced dynamically The plugin languages may be used to support multiparadigm programming or domain specific languages.

고속으로 발전하는 컴퓨터 분야에 있어서 소프트웨어는 좀더 복잡해지고 대형화 되어갔다. 이에 따른 소프트웨어의 테스팅은 소프트웨어 재사용성이나 유지보수, 오류 검출을 하기 위한 하나의 수단으로 사용되어져 가고 있으며, 보편화 되어가고 있다. 그리고 소프트웨어 개발 방법이 구조적 프로그래밍 기법에서 객체지향 프로그래밍 기법으로 변화할 수 옥 이에 따른 소프트웨어 테스팅 역시 구조적 프로그래밍 기법에서 사용하던 테스팅 방법들을 객체지향적 개념에 맞게 바꾸어 나가는 연구들이 많이 이루어지고 있다. 논문에서는 이러한 객체지향 테스팅 기법에서 사용하는 메트릭스들을 선정하여 이를 자바언어로 작성된 프로그램에 적용하고 그 결과물들을 그래픽컬한 표현으로 나타내어 편리한 테스트 환경을 지원하는 도구를 설계 및 구현하였다.

Dolittle is a educational programming language that helps students learning principles and concepts of computer science with programming. Learning programming with robot improve learning achievements robot motivate to be interest with programming. However, Dolittle robot programming is a different from Dolittle programming in process of interpretation and execution mechanism. Therefore, students have virtually to learn two languages to control robot and it would reduce the worth of Dolittle as educational programming language. In order to solve this problem, we tried to Unify Dolittle and robot control language using parser that Dolittle program with turtle object convert robot program. But this try couldn't overcome completely this problem because attributes of turtle object is different from robot. In this research we unified Dolittle programming and Dolittle robot programming as a way of adding new robot object in dolittle standard object group. it would improve educational effect of learning programming with robot in Dolittle.

As a 21C core skill, computational thinking has been focused recently, and computer programming education is popular in primary and secondary schools. This paper aims to analyze the computer programming learning results based on gender difference and verify the reasons causing the difference. In this research, we focused on students' abstract thinking level as a variable and used C programming language and the RUR-PLE. Also, in this research, we focused on the concept of abstraction, one of the main component of computational thinking. And then, we analyze 587 high school students' abstract thinking level and survey them in order to find a new method for enhancing programming skill. In addition, we analyzed the causes for the difference in how the abstract thinking level applies when the students understand various structures of computer programs. From the results, we can propose a computer programming education method that enhances students' merits and compensates their drawbacks in the near future.

Physical computing is the concept of expanding computing to humans, environments, and objects. It draws attention as a programming learning medium based on physical outputs in integration of hardware and software. This study developed a programming learning model based on interactive prototyping using the characteristics of physical computing with a high degree of technical freedom and analyzed its learning effect in an experiment. To examine the effect of the experimental treatment, this researcher divided fifty nine 5th-grade elementary students into an experimental group and into a control group. the interactive prototyping programming learning model was applied to the experimental group, and a linear sequential programming learning model was applied to the control group. Information Science Creative Personality Test was conducted before and after the experimental treatment. Analysis of Covariance was conducted with the pre-test scores of the two groups. As a result, it was proved that there was the effect of learning at the significance level of .05. It indicates that the physical computing based interactive prototyping programming learning model is applicable to the programming learning for 5th-grade elementary students.

Computational Thinking is an analytical thinking ability that is necessary for everyone and everywhere. The existing Computational Thinking development education provided in Practical textbooks leads to block-based programming languages from unplugged activities. Many unplugged activities focus on practicing sequential order, which may lack the learning of abstractions or automation concepts. In block-based programming languages, concepts such as coordinate planes, which are not introduced in elementary school curriculum, appear, making students feel burdened by the block-based programming language itself. In this study, a curriculum was designed for elementary student's computational thinking through game-based programming language education. The results and their effectiveness were analyzed through the beaver challenge. As a result of analyzing the pre-test and post-test scores, it was confirmed that students' computational thinking skills improved.

Most of the robot programming curriculums consists mainly of understanding robot programming language and learning a simple grammatical sentences rather than logical problem solving process, these curriculums impose a burden on childrens' learning. Storytelling offers opportunities for continuation of childrens' positive learning motivation to practice symbolic manipulations, hold multiple abstract concepts in their heads, and create meaning between these ideas. In this paper, to overcome the difficulty of robot programming curriculum in elementary school and find teaching method which derives the childrens' motivation, we used storytelling in study of our robot programming curriculum.

컴퓨터 하드웨어 및 소프트웨어의 발전으로 그래픽 처리 기술은 날로 발전을 거듭하고 있으며 하드웨어의 기능을 최대한 이끌어내기 위한 소프트웨어 기술 또한 발전하고 있다. 이러한 발전으로 인하여 다양한 영상처리 분야에서 빠른 이미지 프로세싱이 가능하게 되었지만 빠른 이미지 프로세싱 능력에도 불구하고 프로그래밍 기술은 기존 것을 고수하고 있다. 일반적으로 사용해오던 기술은 높은 프로그래밍 지식을 필요로 하는 분야였고 이러한 이유로 이미지 프로세싱 기법을 전문적인 프로그래밍 지식이 부족한 예술계의 사용자가 이용하는 데에는 어려움이 있었다. 이러한 문제점을 해결하고 이미지 하드웨어 및 소프트웨어의 효율적인 사용 환경을 위하여 Apple사에서 OpenGL과 Objective-C를 이용한 좀더 간단한 이미지 프로세싱 기법인 코어 이미지(Core Image)를 개발하였다. OS와 어플리케이션 상에서 빠른 이미지 프로세싱을 위해 개발된 코어 이미지는 기존의 이미지 프로세싱 기법에서 복잡한 형태의 프로그래밍을 요했던 것과는 달리, 여러 이미지 프로세싱 기법을 간단한 플러그인 형태로 지원한다. 예술적인 측면에서 다양한 이미지 프로세싱 기법을 보다 손쉽게 사용할 수 있으며 사용 방법 또한 간단하여 전문적인 프로그램 지식이 부족한 일반 사용자도 예술적인 측면에서 이미지 프로세싱 기술을 쉽게 접목할 수 있도록 구성되어 있다. 하지만 코어 이미지가 국내에서는 소수의 사용자만이 이용하는 Mac OS에서만 사용 가능한 프로세싱 기술이라는 문제점 또한 지니고 있다. 본 논문에서는 코어 이미지의 개념과 구동 원리 및 실제 예술 작품에 적용된 사례를 분석하고, 이를 통하여 다양한 분야에서의 코어 이미지의 가능성에 대하여 전망해 본다.

Programming that ensures concurrency is essential for developers. If you do not use it, it is hard to expect the speed of the program to improve unless there is technical advancement of the hardware itself. Programming languages that support good concurrency code include go, elixir, and scala. Python, which supports a number of useful libraries, also supports concurrent programming like asyncio and coroutine. This paper defines the concepts of concurrency and parallelism, and explains what to note when writing concurrency programming in Python. The crawler that collects web data is written in concurrent code and compared with programs written in sequential, multithreaded code.
