In a variety of fields, highly developed technology is being combined to create a lot of value. In order to keep up with this global trend, the Ministry of Education, which is in charge of national education, continuously develops and applies content for creative education to textbooks. The continuous development of content for creative education is not only related to national interests, but also to the continued development of mankind. Today, the succession and development of human knowledge is in charge of the education system. Research into an effective educational system is necessary for effective succession of rapidly developing science and technology and building up technical personnel with such skills. In particular, the computer science field is faster in development than other scientific fields and has accumulated many technologies, indicating that it takes a lot of time and good teaching to foster talent that can effectively utilize the technology. In this paper, elementary school subjects were analyzed to achieve the purpose of cultivating talent in the field of computer science. In addition, we have investigated techniques related to computer programming learning not covered in elementary school subjects. So we developed content that students need to practice. Next, we taught the content to randomly selected elementary school students and assessed their educational effectiveness. As a result of training using the content we developed, 55.37% increased academic performance.

It is reported that programming education contributes to improving problem solving skills by developing higher thinking skills. As many researches mention the need of programming education, they point to the fundamental difference by gender. This study aims to find out the cause of low interest and achievement levels in programming education in female students. To achieve our goals, we chose 133 specialized high school students in which programming class is being carried out as subjects of our study. The results of this study showed that female students had the tendency to prefer individual projects to a more systematic method of problem solving. Moreover, according to correlation analysis, higher programming skills in female students showed various problem solving processes. This study shows significance in proposing different study methods according to gender to obtain effective programming study.

This paper is experimental study to inspect effects of problem solving ability and programming interest using Pico Cricket of the educational robot. The programming learning which is regarded as the very core of information subject improves problem solving ability. But the programming teaming does not display the effects properly, because the programming learning studies a grammar manual. The educational robot has the advantage to approach the programming learning easily for containing entertainment. The Pico Cricket of the educational robot has the advantage not to induce competition but to compose a cooperative learning environment. Also, the Pico Cricket is able to be had interest of programming learning to girl students, because the Pico Cricket is able to suggest life-centered and cooperative contents which girl students like. Accordingly, This paper is study which the programming learning using Pico Cricket affects the problem solving ability and programming interest and men and women's comparison study.

This paper presents the results of adopting pair programming practices in an introductory university programming course. The effectiveness of pair programming is analyzed by comparing the performance and survey data gathered from the experimental class that adopted the practice to those from the control class that did not. An analysis of the performance data found that pair programming improved student performance; however, not all students in the pair programming class benefited from the practice as only some students showed clear improvements in learning outcomes. The survey showed that the specific method for matching students into pairs is a critical factor affecting their performance and satisfaction. Based on the lessons learned from this pair programming class, I propose some suggestions and guidelines for applying pair programming to programming classes including 'pair matching'.

The purpose of this study was to investigate whether the experience of computer programming in Logo geometry advances the development of young children's concepts and/or representation of Euclidian spatial relations, particularly their concepts of the vertical-horizontal. Papert's claim of the positive effects of Logo programming experiences on young children's cognitive development was tested using the Piagetian Water Level Test (PWLT), the Free Hand Drawing Test (FHDT), and the Computer Drawing Test (CDT). Forty-four subjects were drawn from 2nd graders attending a public elementary school in Ithaca. The subjects were divided into 2 groups: a treatment group (TG) with Logo training for 10 weeks and a control group (CG) without Logo training. Our results showed that TG did not make any significant improvement on PWLT. In contrast, TG outperformed CG on FHDT. We suggested several possible explanations for this contradiction.
