Many people are showing interest on computing and computer programming ever as much as the smartphone become more popular. Computer programming languages, however, like Java or C++ being used to teach freshmen in computer science-related majors as the first programming language they will study are so difficult to understand. In this paper, we proposed a short-term curriculum for teaching computer programming using App Inventor for Android to freshmen students major in computer science as the first programming language they will study, which can encourage their interest in computer programming. According to survey from students participated in actual teaching, we found that the proposed curriculum can contribute to increase their interest on computer programming and even self-confidence on development of applications for smarphone.

In this paper, we report a case study of applying puzzle solving as a programming practice. There are many students, who have attended computer programming language courses, have had difficulties in accomplishing the course assignments. It is because just following and citing the programming language course materials is not sufficient for constructing computer programs. Many professional developers have stated that computer programming for small problems is an art of puzzle solving, where developing enterprise-size computer programming projects involves architectural insights which are already dealt in software engineering literatures. Following those backgrounds, we have explored the applicability of puzzle solving in a C++ object oriented programming course and have reported the results. The experimental results show that puzzle solving is effective to the students who are interested in computer programming and have at least beginner-level knowledge and expertise, but it turned out that puzzle solving assignments still does not draw much attention of the students who are not seriously interested in computer programming.

As the 2015 revised curriculum is implemented and the software education is emphasized, the education field demands more informatics teachers with computational thinking and programming skills. In this thesis, we have studied ways to improve the practical evaluation of informatics·computer teacher-appointment test so that a preliminary teacher can be selected through the evaluation of programming skills. We analyzed existing informatics·computer appointment tests and conducted questionnaires for professors and teachers to suggest improvement and expansion of practical skill evaluation. According to the results from the questionnaire, 88% of the respondents answered that expanding the evaluation of programming practice is necessary. In the questionnaires regarding the programming language, the number of questions, and the test time, the highest response rate was C language(51%), 5 questions(66%) and 2 hours(56%).

In this paper, we study whether the programming questions of the Informatics·Computer recruitment tests were suitable for selecting teachers with required programming skills. The average points of the programming questions constituted 38%(20.8 points) of the total scores for the entire curriculum based on the results from analyzing the previous questions in the past 5 years. Moreover, the distribution of points for each evaluation criteria within programming and data structure, two exam subjects which have a high proportion of programming questions, demonstrated a large deviation ranging from 0% to 47% and 0% to 53% respectively. In this study, a questionnaire survey was conducted on 31 teachers to examine if the previous programming questions were suitable for measuring teachers' competency in programming abilities required in the actual teaching experience. Computational thinking ability was ranked the highest at 58% in response to the area that needs to be evaluated in the recruitment test. In response to the relevance of previous questions, problem solving ability was ranked the highest at 2.84 on a 5-point scale, but the overall appropriateness was deemed low. C language and Python were regarded as the computer languages suitable to be tested for programming questions with each ranked 55% and 45%. The finding confirms that teachers preferred Python and the incumbent C language to others. Based on the results of the questionnaire, we recommend changes in the programming questions to improve the selection criteria.

There is an increasing concern about computer education with the age of knowledge-based society. The learning programming language is taking an important role of computer education. However, the special emphasis in learning programming language has been attached to memorizing the programming language by rote and learning computer programs. Therefore, those were not much useful tools to develope a logical intelligence of the meanings of programming language and the methods of realization. It is positively necessary to improve the programming education efficiently because of the objects of knowledge of computing and raising an efficiency of problem solving. Under the circumstances, this research is aimed at representing an useful education model through developing a mathmatical program into each part of the C programming language, which would be a new supplier of an basic insight into the programming language and techniques. Accordingly it is thought that the research material will be an useful model to increase interests and concerns as well as to raise an efficiency of problem solving or a logical intelligence going through the process of studying programming language.

Engineers increasingly rely on computers and their computer programming skills for their works. As a result, most engineering curricula have introduced a computer programming courses. However, students consider the subject to be unrelated to their core interests and often feel uncomfortable when learning to program for the first time. To overcome these difficulties, several studies have proposed the use of physical computing paradigm. This paradigm takes the computational concepts out of the PC screen and into the real world so that the student can interact with them. This paper proposes Arduino platform as a tool for attracting interest of the programming and reports the results of questionnaire survey analysis.

This paper proposes several methods for effective teaching of programing language(especially C). The programing languages are very important and basic subjects in the Department of Computer Engineering and Science. Many students have some difficulty in learning the programming languages. So, we will suggest several effective methods for effective teaching of programming languages. First, in order to understand the programming language effectively, we need to teach some basic computer architecture and operation principles of computer program to students. Second, it is better to teach many example-based programing skills instead of conventional grammar teaching. Third, if we teach the memory status(memory allocation/release) during the program operation, it will be much better to understand the pointer variables and memory problems. Fourth, let's improve the programming skills through effective homework assignments and experiments. Fifth, let students be guided so that they do programing by themselves. Finally, we can maximize the programming skill through the final termproject.

This paper presents a windows application for voltage sag analysis and effective data visualization. The developed Voltage Sag Analysis Tool (VSAT) was designed by using the Object-Oriented Programming (OOP) concept and C++ programming language. The VSAT provides basic functions for voltage sag analysis such as power flow analysis, short circuit analysis and stochastic analysis. In particular, the VSAT provides effective data visualization through computer graphics and animation. Analysis results are expressed realistically and intuitively on geographical display. The Graphic User Interface (GUI) of VSAT was designed specifically for voltage sag analysis. In this paper, the development and implementation of VSAT is presented. In order to demonstrate the capabilities of VSAT, it is used to analyze the Jeju Island power system in South Korea.
