Artificial intelligence education is very important in the 21st century knowledge information society. Even if it is very important to understand artificial intelligence and practice computer programming in computer education in the fourth industrial revolution, but there is no teaching and learning model to understand artificial intelligence and computer programming education. In this paper, the proposed model consists of problem understanding step, data organizing step, artificial intelligence model setting step, programming step, and report writing step. At the program step, students can choose to copy, transform, create, and challenge steps to their level. In this study, the validity of the model was proved by the Delphi evaluation of elementary school teachers. The results of this study provide a good opportunity for elementary school students to practice artificial intelligence programs.

This study investigated the definition and characteristics of computer science problem to be solved through computational thinking. It also explored types and cases of both computer science problems and teaching learning methods to solve computer science problems. Before studying computer science problems, I examined the definition, type, and the importance of problem solving in other subjects. Based on this research, We found that informatics can solve ill-structured problems through computational thinking and the power of computing. This includes counting, decision, retrieval, and optimization problems. Teachers can improve their students' skills in computational thinking, particularly as related to abstraction, automation, and generalization, by choosing the appropriate teaching and learning method or based on the characteristics of the problem.

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.

Since educating digital convergence is to unite various sciences and technologies with computer as the central figure, it has different range and methods of education. Therefore, it has problems with recommending limited conceptual information because of difficulties to standardize education plan and teaching strategies. In this paper, I propose education plan and teaching strategy system by using Spearman correlation coefficients. This system is to find a solution against disadvantage of recommending limited conceptual information by ranking relations of teaching strategies from the information based on the demand of industrial and academic fields, and then provides lists of teaching strategy information suitable for user's atmosphere and characteristics. Performance test is to compare effects of precision and recall with existing service systems. The test shows 90.4% of precision and 77.6% of recall.

With the rapid development in computer hardware and software in recent years, the contents and methods of teaching English have been altered greatly. The use of multimedia and the Internet as a means of language teaching is increasing as information technology accelerates. Using multimedia and the Internet in language teaching allows teachers to have more time to devote to interacting with their students. Above all, it arouses in students the motivation for learning and enables each student to study with the speed commensurate to his/her own ability. Both teachers and students can choose their own style that is most efficient for their classes. When students are efficiently stimulated through visual and auditory materials, they can be more easily motivated to utilize and develop creative techniques by using multimedia and the Internet. Thus, in the information age, it would be desirable to innovate the existing concepts of lineal education and allow more student-centered lessons to more readily expose students to contents and experiences according to their own demands.

In this study, optimum structural designs of braced (non-swaying) planar steel frames are investigated by using one of the recent meta-heuristic search techniques, teaching-learning based optimization. Optimum design problems are performed according to American Institute of Steel Construction- Allowable Stress Design (AISC-ASD) specifications. A computer program is developed in MATLAB interacting with SAP2000 OAPI (Open Application Programming Interface) to conduct optimization procedures. Optimum cross sections are selected from a specified list of 128W profiles taken from AISC. Two different braced planar frames taken from literature are carried out for stress, geometric size, displacement and inter-storey drift constraints. It is concluded that teaching-learning based optimization presents robust and applicable optimum solutions in multi-element structural problems.

This paper presents a user interface for vision based indirect teaching of a robotic manipulator with Kinect and IMU (Inertial Measurement Unit) sensors. The user interface system is designed to control the manipulator more easily in joint space, Cartesian space and tool frame. We use the skeleton data of the user from Kinect and Wrist-mounted IMU sensors to calculate the user's joint angles and wrist movement for robot control. The interface system proposed in this paper allows the user to teach the manipulator without a pre-programming process. This will improve the teaching time of the robot and eventually enable increased productivity. Simulation and experimental results are presented to verify the performance of the robot control and interface system.

It is the development of a mathematics teachers' teaching knowledge that manifests a mathematics teacher's professional knowledge growth. It is becoming a direct and effective approach of conversion of mathematical knowledge into the knowledge of mathematics teaching. Through the investigation, the study revealed that the knowledge conversion process of mathematics teachers in middle school is restricted by three aspects including eight factors. From this point, the authors have structured the path and model on influencing factors of middle school Mathematics Teaching Knowledge Conversion (MPCK), and discuss the mechanism of the transformation process.

Elementary school students have a little awareness of privacy protection since they do not have many opportunities for systematic education on information and communication ethics. Hence, they are likely to expose their own information to others and sometimes bring on a lot of misuses by using others' information. In this paper, we provide an idea for teaching and learning methods which the elementary school students acquire privacy protection and management methods and raise their practical capabilities. We develop a role play teaching and learning model in connection with various Information and Communication Technology (ICT) activities and establish the instruction plans. Moreover, we apply them to the actual classes at grade five and six of the elementary school students respectively, and finally analyze the results. The proposed teaching and learning method shows that the students participated in a series of learning activities have higher learning effects on awareness of privacy protection than those learned with the conventional methods.
