Lately, studies on the educational effectiveness of educational programming language which can reduce the learning burden of the learners have been conducted in the programming learning process. This study analyzed the effect of programming education on the learning motivation and academic achievement after training the programming education using Scratch and Dolittle on the preliminary elementary school teachers. As a result, the experimental group trained by Scratch programming education showed significantly higher achievement than the control group by Dolittle Programming. This result can be helpful in selecting educational programming language when the programming education will be trained to the preliminary elementary school teachers.

The demand for learning programming anywhere at a low cost at any time is increasing. Accordingly, there have been a great number of web-based programming courses. Generally, teaching Web-based programming classes is very challenging. Thus effective methods for teaching these courses should be researched. Based on several years of experiences in teaching a Web-based programming course as well as the related literature, this paper presents its effective teaching strategies. First, some design strategies of its course contents for developing programming skills are proposed, considering the characteristics of programming courses as well as potential learners. Next, its effective assessment and class management strategies are proposed. Finally, we evaluate the results of student grades and operation of a Web-based programming course offered most recently using proposed strategies. They demonstrate that we can enhance learning effects of the course.

As IT technology improves, software is being more and more important. Industry demands higher level of programming ability from university graduates. As a result, programming related courses already take higher possession of electronics department curricula. But even though the environment likewise computer laboratory is improved as much, and professors have tried to enhance the quality of their lectures and educational results, still programming education does not match the demand of our society and industry. In this paper, we introduce the overview of programming education in electronics department, KUT and discuss problems in programming language education especially for the 1st year students, since programming education to the 1st year university students becomes one of the most important part as it deals with fundamentals on programming language and we suggest its improvement directions in regards with students, teaching materials, professors, class size, and class hours.

There generally exists a large variation in the thereshold voltages of the flash EEPROM cells after they are erased by using th fowler-nordheim tunneling, thereby getting some cells to be overeased. If the overerased cells are programmed with the conventional one-step programming scheme where an 12-13V pulse with the duration of 100.mu.S is applie don the control gate for the programming, they can suffer from the significant degradation of the reliability of the gate oxide. A two-step programming schem, where an 8/12 V pulse with a duration of 50.mu.S for each voltage is applied on the control gate for the programming, has been studied to solve the problem. The experimental results hav eshown that there is little difference in the programming characteristics between those two schemes, whereas the degradation of the gate oxide due to the programming can be significantly reduced with the two-step programming scheme compared to that with the one-step programming scheme. This is possibly because the positive charge stored in the floating gate of the overerased cells is compensate dwith the electrons injected into the floating gate while the 8V pulse is applied on the control gate, which leaves the overerased cells in the normally erased state after the duration of the 8V pulse.

This paper suggests an efficient approach for stochastic bicriteria programming problem (SBCPP) with random variables in both the objective functions and in the right-hand side of the constraints. The suggested approach uses the statistical inference through two different techniques: In one of them, the SBCPP is transformed into an equivalent deterministic bicriteria programming problem (DBCPP), then the nonnegative weighted sum approach will be used to transform the bicriteria programming problem into a single objective programming problem, and the other technique, the nonnegative weighted sum approach is used to transform the SBCPP to an equivalent stochastic single objective programming problem, then apply the same procedure to convert stochastic single objective programming problem into its equivalent deterministic single objective programming problem (DSOPP). In both techniques the resulting problem can be solved as a nonlinear programming problem to get the efficient solutions. Finally, a comparison between the two different techniques is discussed, and illustrated example is given to demonstrate the actual application of these techniques.

Programming is emphasized in information(computer science) education course domestically and in foreign countries, and novices are given ample opportunities to experience programming. Programming error is a critical factor which makes it difficult to learn programming for novices. However, if they are given appropriate feedback, it can have positive influence on programming learning. In this paper, we design programming learning supporting system for novice through error feedback and provide some implementations for EPL 'Dolittle'. This system has four features as highlighting, guiding messages, object tree, and step-execution.

In distributed office, the pairs can program together using a distributed pair programming system. Many CSCW tools featuring remote screen sharing function have insufficient usability, accessibility to introduce many developers to distributed pair programming. In this paper, we suggest a distributed pair programming system based on IDE, which many developers will accept and use easily. We have do#eloped a user scenario and GUI of the system, making distributed pair programming easier and designed with high extensibility by adapting design patterns and implemented in Java language. Our findings will be of significant help to developers dealing with implementation of distributed pair programming function into some commercial IDE.

This paper presents a new approach to solve the multi area unit commitment problem (MAUCP) using an evolutionary programming based particle swarm optimization (EPPSO) method. The objective of this paper is to determine the optimal or near optimal commitment schedule for generating units located in multiple areas that are interconnected via tie lines. The evolutionary programming based particle swarm optimization method is used to solve multi area unit commitment problem, allocated generation for each area and find the operating cost of generation for each hour. Joint operation of generation resources can result in significant operational cost savings. Power transfer between the areas through the tie lines depends upon the operating cost of generation at each hour and tie line transfer limits. Case study of four areas with different load pattern each containing 7 units (NTPS) and 26 units connected via tie lines have been taken for analysis. Numerical results showed comparing the operating cost using evolutionary programming-based particle swarm optimization method with conventional dynamic programming (DP), evolutionary programming (EP), and particle swarm optimization (PSO) method. Experimental results show that the application of this evolutionary programming based particle swarm optimization method has the potential to solve multi area unit commitment problem with lesser computation time.

The positive impacts of robotics education and programming education on learners are similar. However, robotics education differs from programming education because it includes purchasing and building robots that cause financial and cognitive load of learners. Due to these differences, two kinds of education may not possess equal efficacies for all schools or all learning objectives. To verify this hypothesis, we conducted meta-analysis of studies on robotics education published in South Korea to estimate the effect sizes and compare it to that of programming education. The difference between the average effect sizes of robotics education and of programming education was significant, as the former was 0.4060 and the latter 0.6664. The average effect size of programming education was significantly larger than that of robotics education for primary school students. Middle school students achieved the highest results in both robotics education and programming education. Also, robotics education became more effective than programming education as students were older. Analysis on objectives showed that programming education uniformly affected all areas, whereas robotics education had more impact on affective domain than cognitive domain. Robot construction had the largest effect size, followed by robot construction and programming, robot programming, and robot utilization. Programming education has larger positive impacts on students overall compared to robotics education. Robotics education is more effective to upperclassmen than programming education, and improves affective domain of students. Also, robotics education shows higher efficacy when combined with various subjects.

Since 2008, it has been stipulated to conduct programming education for grade 5 and 6 elementary school student. However, it is the reality that the plans and studies for this are seriously lacking until now. The objective of this study is to propose a programming education utilizing robots as a plan to overcome limitations of existing programming education, find the problems through developing and applying education program for general elementary school students. As a result of experimental application of the developed program, since the gap of academic accomplishment for the robot programming is large for each student, it is necessary to develop education program to enable individual studies of each level and operate program with the focus on programming education rather than the robot. Moreover, it is pointed that the difficult and unnecessary elements in the robot programming course must be improved or reduced, it is better to exercise it on the grade 6 program for concentration on the programming education, and there should be improvement on equipment, environment for robot programming.
