Today computer education puts an emphasis on algorithm education. There are little researches about how to express the given problem in algorithm and how to interpret the expressed algorithm. In this study play-based learning methods dealing with flow chart which is one of the expressing tools of algorithm are developed for lower graders of elementary school. Then we diagnosed the learning possibility of the tool after applying the methods in a classroom environment. There are four types of learning game activities; sequential play, selective play, repetitive play and puzzle play. Puzzle play is a game that students need to reconstruct the learned content to a real flow chart by using flow chart cards. The result of an achievement test after teaching students flow chart showed that the group who took the play-based lesson got their average score with about 7.5% higher than the group who took the ICT-based lesson. Both the groups got their average scroe of more than 9 out of 10 after the lesson. This result shows that flow chart lessons are adaptable for the lower graders of elementary school. It also shows that play-based education can be exceptionally effective.

When we are teaching the programming education, it is very useful if we show that a flow chart generate automatically owing to a written out of the program. In this paper, we introduce the method of a flow chart generating from the simple imperative language for the While program. After the While program is translated by the Flow Chart Language program, it is generated automatically by making use of the java graphic library. Taking advantage of our results of the study, beginners can understand the flow of the program easily.

The T-s chart of air displays graphically the thermophysical properties, so it is very conveniently used in various thermal systems. In previous study, the software analyzing 31 kinds of values in water system and 32 kinds of values in air-conditioning system were developed. In this study, the software drawing 13 kinds of quantity of state on air properties as ideal gas and analyzing 25 kinds of values in any air system was developed. The 13 kinds of quantity of state on air properties are temperature, pressure, specific volume, specific internal energy, specific enthalpy, specific entropy, specific exergy, exergy ratio, density, isobaric specific heat, isochoric specific heat, ratio of specific heat, and velocity of sound, and the 25 kinds of values including 13 kinds are mass flow rate, volume flow rate, internal energy flow rate, enthalpy flow rate, entropy flow rate, exergy flow rate, heat flow rate, power output, power efficiency, reversible work, lost work, and relative humidity. The developed software can draw any range of chart and analysis any state or process on air system. Also, this supports various document-editing functions such as power point. We wish to this chart is a help to design, analysis, and education in air system field.

본 연구에서는 초등에서 알고리즘 교육의 방법으로 사용되는 언플러그드 활동에 순서도를 활용하는 방안을 제안한다. 소프트웨어 교육의 기본적인 방향은 컴퓨팅 사고력을 기반으로 문제를 해결하는 역량을 기르고자 하는 것[1]이지만, 현재는 교육용 프로그래밍 언어의 학습에 치우쳐 있거나 알고리즘 교육이 제대로 이루어지고 있지 않다. 언플러그드 활동에 순서도를 활용함으로써 알고리즘 영역의 교육을 강화하고 균형 잡힌 컴퓨팅 사고력 함양에 도움이 될 것이다.

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.

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.

The curriculum of programming education including algorithm has been recognized as a very important subject to many students majoring in natural sciences and engineering including electronic engineering and computer related departments. However, many students have had difficulties with it due to its characteristics; as a consequence, they have been in trouble taking upper-level subjects. Flow chart is a diagram that expresses logical stages necessary to solve certain problems and has been widely used to have an understanding of the flow of algorithm. The practice-oriented education of algorithm and programming would be very important to assist the understanding of operation processes. Furthermore, it has been desperately required to the necessity of auxiliary programs that could enhance an understanding of the concept of algorithm and program execution process. This study was aimed to design and embody the learning system of programming languages using basic algorithms so as for students to easily learn basic algorithm among the entire programming curriculum.

This paper presents a graphical windows-based software for the education and training of transmission network charge. The motivation for the development of the simulator is to provide students with a simple and useable tool for gaining an intuitive feel for transmission network charge. The developed simulator consists of the main module (MMI, GUI), the power flow module (PF), the power flow tracing module (PFT), and usage cost DB module (UCD). Each module has a separate graphical and interactive interfacing window. The developed simulator provides with two power system analysis methods (i.e., DC-PF and Modified DC-PF) and supports the PSS/E input data format to load input data of power system. Also, power flow tracing can be calculate using four methods such as "Felix Wu", "Modified Felix Wu", "DCLF ICRP", and "Reverse MW mile". Results of calculation for transmission usage cost are displayed and compared on the window through the table and/or chart. Therefore, the developed simulator can be utilize as a useful tool for effective education and training of transmission network charge.
