The programming(algorithm) automated assessment system is to evaluate automatically the accuracy and time/space efficiency of user's solution to the problem which is provided. This system gives the immediate feedback of the solution, real-time ranking. So, in the course of data structure and algorithm, we can apply the knowledge which we have learned to the problem solving. Especially, in the basic course of learning the syntax of the programming language, the novice student can learn in easy and fun by solving the simple problem. The university students can understand in the easy way the meaning of asymptotic analysis of algorithm in data structure & algorithm course.

본 연구에서는 21세기 지식정보사회에 학생들의 창의력 향상을 위하여 MSRDS에서 제공하는 에디터인 VPL(Visual Programming Language)를 이용한 로봇 프로그래밍 학습이 창의력에 미치는 효과를 연구하였다. VPL은 로봇 애플리케이션 개발을 프로그래머가 아닌 학생들도 쉽게 사용할 수 있도록 MSRDS에서 제공하는 프로그램이며, 이를 시뮬레이션과 연결시켜 로봇 하드웨어가 없이 손쉽게 학습을 할 수 있게 하였다. 이를 위하여 VPL에서 사용하는 기본 Activity를 이용하여 프로그래밍의 구문을 자연스럽게 학습할 수 있는 수업 내용을 개발하였으며, 연구 대상은 충청남도 B군에 위치한 B공고 3학년의 컴퓨터응용관련 학과 1개반을 대상으로 C언어를 이용한 기존의 마이크로 장비 프로그래밍 수업과 VPL을 이용한 로봇 프로그래밍 수업을 상호 비교하려고 한다. 이 연구에서는 VPL을 통하여 손 쉽게 프로그래밍을 하고 흥미가 유발되어 자신이 생각한 대로 로봇의 동작을 구현하는 과정에서 자연스럽게 문제해결능력이 신장된 것을 확인하고자 한다.

The purpose of this study is to provide considerations through investigation and analysis about non-computer major learners' difficulties in computational thinking education. In recent, the importance of human resources development in convergence based on computational thinking is increasing internationally and a Korean university is selecting CT as a mandatory subject. I taught CT with Scratch at C university in Seoul for two semesters in 2014 and investigated and analyzed what difficulties non-Computer majors felt in the process of CT education. The result showed they felt the following some difficulties in order: the concept of variable and list; to think a idea and implement it; which commands should be selected. The pleasure and the interest can be apply to decrease difficulty, because they affect self-programming ability and self-CT capability each other statistically. Although Scratch is an easy and an intuitive programming language, it is needed to consider to provide appropriate learning time to student for using and applying commands.

컴퓨터와 하드웨어의 발달과 더불어 데이터 통신기술은 인터넷을 필두로 하여 괄목할만한 발전을 가져왔다. 아울러 FTP, Telnet, SMTP, HTTP, DHCP등의 네트워크 응용 프로토콜도 속도와 유저 인터페이스에 있어서 수많은 변화가 있었다. 하지만 이러한 외형적인 변화에도 불구하고 TCP, UDP 방식의 Socket 프로토콜은 네트워크 프로그래밍의 가장 기초적인 원리를 제시하고 있는데, 초보 학습자들에게 있어서 Socket을 구성하는 많은 시스템 함수들을 모두 이해하고 이것을 프로그래밍에 적용하기란 쉬운 일이 아니다. 본 연구에서는 Socket의 많은 함수들을 API기반의 모듈로 캡슐화 하여 C/C++ 기반의 네트워크 프로그래밍을 보다 손쉽고 효율적으로 수행할 수 있고, 또한 네트워크 프로그래밍의 동작 원리를 효과적으로 프로그래밍 학습에 적용할 수 있는 전산 교육시스템인 네트워크 프로그램 소스 생성기를 제안 한다.

The concept for algorithm needs to be established in various fields such as architecture, medicine and life science but understanding only theoretically has its limits. It is therefore educated using many multimedia factors but still is difficult to bring interests and carry out the higher level courses. For algorithm and programming, due to the subject's peculiarity it is very important to actually execute the program to understand the realization theory. In this paper, it aims to design a basic concept of algorithm using a flow chart of visualizing program and an algorithm education system to learn the basic programming C language, which is the fundamental element in algorithm learning.

When you look at computer training techniques, generally you will see an unbalanced focus towards the software applications being used. Office programs, including software applications, or simply the ability to operate has been assigned in the attempt to develop more information. Omitted, while a students thought process dealing with computer applications is usually clear and effective, the functional oriented tasks involved are time consuming. In order to keep up with the pace of today changing requirements, creativity and problems solving ability is a necessity. These are the areas in which both our training techniques are inefficient, and the resulting ability of student's is unsatisfactory. In this study of 5thand6thgradelevelcomputerteachingtechniques.

This paper deals with AI education service that enables developers who have completed basic programming education to program in C/C++ language in order to learn big data and artificial intelligence. In addition, a customized development environment configuration system according to the development environment and how the user implements and tests artificial intelligence are explained. And also it has a function to check the effect on artificial intelligence through manipulation of various internal parameters. It is expected that it will be possible to develop artificial intelligence education services without language restrictions through networks in the future.

There have not been integrated courses for education of C and Java programming languages in most universities. Based on similarities and uniqueness and the previous lecturing of each language, we designed and made an integrated programming course. In this paper, we introduce the web-based contents which make the successful and effective application of the new course. The web-based contents consist of the main page, the course materials, the auxiliary materials, and the bulletin board, and supports a variety of practices with the examples. From the application of the web-based contents to the practical lectures, we notice that understandability, satisfaction, and the programming skills of students significantly increase comparing to that of the previous respective courses.

In this paper, we propose a web-based programming class support system to help a lecturer to teach a programming language to students effectively. The proposed system is composed of a error analysis step and a verification step. The error analysis step checks whether there are compile time errors or run time errors in each student's submitted program. Given some errors, the system provides helpful feedback for the student to fix the errors. On the contrary, the system provides quick feedback after checking the source code style, comments, and plagiarism in the submitted program. As soon as the student submits the program, the student can see the check results. According to the result of utilizing the proposed system in a C programming language class, students tend to submit program assignments actively.

In this paper, we show how a curriculum using LEGO MINDSTORMS NXT robot based ROBOTC for undergraduate students has been developed, and we analyze the educational effect of the curriculum. The curriculum is composed of basic knowledge learning, practice with basic robots, practice with advanced robots, and creative design and implementation of robots. During the three year period since 2009, educational achievement has been analyzed by surveys for 6 classes, 94 students. According to the analysis, the curriculum has highly motivated the students and made them to achieve effectively our educational and academic goals. Also, we observe that the curriculum helped the students to improve their creativity and the problem solving skill, and that the students were autonomously and deeply involved in the homework and the term projects, which made them be very cooperative. Finally, the intensive practice with ROBOTC programming is shown to help students to improve their programming ability of C language.
