Team-based programming methods are widely applied to solve various difficulties that pre-service teachers experience in the programming lessons. To prepare effective collaboration strategies necessary for them, it is necessary to analyze various collaborative factors that affect learners' programming competencies. Therefore, in this article, a questionnaire survey was conducted by dividing learners' collaboration factors into individual and team competencies, and the relationship between learners' programming competencies was analyzed. As a result of the verification, the program design competency showed significant results in all elements of the learner's personal competency, team techniques such as data sharing skills necessary for collaboration, and team collaboration. It was analyzed that an individual's understanding of learning and team collaboration influenced the program implementation competency. In addition, the group with relatively high team technique showed significant differences in programming competence, interest, and satisfaction. Accordingly, by linking meaningful factors related to individual and team competencies according to the programming process, a collaborative strategy practically necessary for pre-service teachers was suggested.

As we have entered into the 21st century knowledge and information society, the necessity of computer education has emerged and even its expectation is getting bigger. In spite of that, the present computer education neglects computer programming education which may be the basis of information, as understanding it only as the ability to utilize computer that deals with the usage of application program. Through the programming experience, students are likely tn understand abstract concepts on computer hardware, and to acquire knowledge needed tn solve problems given to them through computer. In this paper, on the basis of the significance and necessity in programming education, using a questionnaire, analyzed the necessity in programming education based upon responses of elementary school teachers to investigate the recognition analysis of elementary school teachers about programming education in elementary schools.

The purpose of this study is to ermine the effect of digital storytelling as a strategy of programming education to improve students' learning motivation and achievement. To overcome the difficulty of programming education in elementary school and find teaching method which derives the students' motivation, we used a digital storytelling in programming class. Digital storytelling that is considered as an important factor of edutainment gives interest to learners with interaction and stories for programming materials. The result is that elementary school students are more interested in programming and attend actively and their motivation and achievement is improved. Therefore it can gives elementary school students a positive experience with programming that will hopefully contribute to a more positive attitude towards computer science.

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.

This study addresses basic requirements for mathematical programming software, discusses considerations in designing these software, implementation issues facing in these types of applications development, and shows some examples of codes being developed in the course. This type of projects requires long and ever-changing evolutionary phases. The experience is therefore, valuaable in suggesting some useful hints which may be salvaged for similar projects as well as providing reusable codes. In particular, scanning and parsing the free-format inputs, symbol table management, mixed-language programming, and data structures dealing with large sparse matrices are indispensable to many management science software development. Extensions to be made are also discussed.

In this paper, we use scratch to design and develop non-formal learning experiences that are linked with contents of secondary science textbook to educational programs. The goal of this paper is to develop a convenient and interesting program for non-formal learning in a learning environment using various smart device. Theoretical approaches to mobile education, such as smartphones, and smart education support policies continue to lead to various research efforts. Although most of the smart education systems developed for students who have difficulty in academic performance are utilized, they are limited to general students. To solve the problem, the learning environment was implanted by combining the scratch, which is an educational programming that can be easily written. The science education program proposed in this paper shows the result of process of programming using ICT device using scratch programming. In the evaluation stage, we were able to display the creations and evaluate each other, so that we could refine them more by sharing the completed ideas.

The purpose of this study is to derive implications by grasping how the occupational identity of vocational training teachers who teach programming in vocational training field was formed. Teacher A, who has been engaged in programming education and training for over 20 years, was interviewed in a narrative research. For the research question 'what is the occupational identity formation process of programming vocational training teachers?' It was found that educational experience had an effect on the formation of occupational identity. This study is meaningful in that it attempted to investigate the process of forming occupational identity of programming vocational training teachers and to examine its meaning. Proposals for future research are as follows. First, in the follow-up study, it is necessary to study a wide range of experiences targeting various programming vocational training teachers according to age, working period, and affiliated institutions. Second, it is necessary to study policies and issues experienced in the field.

In recent years, several computer-aided pattern recognition and data mining techniques have been developed for modeling of soil behavior. The main idea behind a pattern recognition system is that it learns adaptively from experience and is able to provide predictions for new cases. Artificial neural networks are the most widely used pattern recognition methods that have been utilized to model soil behavior. Recently, the authors have pioneered the application of genetic programming (GP) and evolutionary polynomial regression (EPR) techniques for modeling of soils and a number of other geotechnical applications. The paper reviews applications of pattern recognition and data mining systems in geotechnical engineering with particular reference to constitutive modeling of soils. It covers applications of artificial neural network, genetic programming and evolutionary programming approaches for soil modeling. It is suggested that these systems could be developed as efficient tools for modeling of soils and analysis of geotechnical engineering problems, especially for cases where the behavior is too complex and conventional models are unable to effectively describe various aspects of the behavior. It is also recognized that these techniques are complementary to conventional soil models rather than a substitute to them.
