In this study, trends in ICT education were investigated by analyzing the frequency of appearance of keywords related to machine learning and using conversion of iteration correction(CONCOR) techniques. A total of 304 papers from 2018 to the present published in registered sites were searched on Google Scalar using "ICT education" as the keyword, and 60 papers pertaining to ICT education were selected based on a systematic literature review. Subsequently, keywords were extracted based on the title and summary of the paper. For word frequency and indicator data, 49 keywords with high appearance frequency were extracted by analyzing frequency, via the term frequency-inverse document frequency technique in natural language processing, and words with simultaneous appearance frequency. The relationship degree was verified by analyzing the connection structure and centrality of the connection degree between words, and a cluster composed of words with similarity was derived via CONCOR analysis. First, "education," "research," "result," "utilization," and "analysis" were analyzed as main keywords. Second, by analyzing an N-GRAM network graph with "education" as the keyword, "curriculum" and "utilization" were shown to exhibit the highest correlation level. Third, by conducting a cluster analysis with "education" as the keyword, five groups were formed: "curriculum," "programming," "student," "improvement," and "information." These results indicate that practical research necessary for ICT education can be conducted by analyzing ICT education trends and identifying trends.

The 2007 revised curriculum designated information-related subjects informatics and changed the direction of education by stressing problem-solving skills in consideration of the characteristics of the subject. The purpose of this study was to examine whether the problem-solving method and process sections of informatics textbooks had an inquiry tendency to foster the problem-solving skills of students. Four textbooks that were widely selected from among the authorized textbooks were analyzed by utilizing Romey method. As a result, just one textbook was found to have an inquiry tendency in terms of texts, but every textbook had a sufficient inquiry tendency in terms of activities. But in terms of structure, there were some problems that commercial softwares were utilized and some softwares employed a particular programming language. The findings of the study suggest that no question should be posed about intrinsic inequality in conjunction with textbook selection, and that textbooks should be structured not to make students adversely affected by learning environments.

This study presents a step-by-step analysis of the experiences and discussions of five elementary school teachers while developing the Augmented Reality (AR) science educational materials, using the Unity Physics Engine. In the preparation phase to develop the AR materials, the teachers explored the features of the AR technology and decided to create AR materials for experiments related to magnetic fields in the magnetism unit, based on discussions about the unit selection. In addition, they complained about difficulties arising out of the lack of background knowledge about the C# programming language in the preparation phase. During the material development stage, there were difficulties in operating the unfamiliar interface and other functions of the software. However, this was overcome through knowledge sharing and collaborative communication among the teachers. The final materials developed were marker-type AR materials to perform experimental activities by changing the position of the magnet and the compass markers. Based on the developed materials, the teachers discussed their smooth utilization during the classroom activities.

The purpose of this study is to examine the effectiveness of the summer enrichment programs on Korean gifted students' science learning and creativity development. This program is organized by Purdue University Gilled Education Resource Institute (GERI) in U.S.A. Researchers conducted semi-structured interview with 6 Korean students and observed 12 Korean students and GERI teachers for teacher-student interaction and teaching strategies during science-related classes. From the results, GERI program developed from Purdue 3 stage enrichment model that emphasizes creative teaching strategies, group discussions, and individual research were effective to foster creative thinking of Korean gilled students. Despite their language barriers, Korean gilled students found GERI program experience fun, creative, easy, relaxing, and thereby satisfying for their psychological and academic needs. They expected the level of stimulation in GERI program to be higher and the class to be organized more systematically; however, they reported that the broad range of topics and diverse content of GERI classes helped them develop creativity more than Korean classes. These findings will make contribution to the improvement of the quality of gifted education curriculum and programming in Korea.

India is a developing nation and has come with comprehensive way in modernizing its reducing poverty, economy and rising living standards for an outsized fragment of its residents. The STEM (Science, Technology, Engineering, and Mathematics) education plays an important role in it. STEM is an educational curriculum that emphasis on the subjects of "science, technology, engineering, and mathematics". In traditional education scenario, these subjects are taught independently, but according to the educational philosophy of STEM that teaches these subjects together in project-based lessons. STEM helps the students in his holistic development. Youth unemployment is the biggest concern due to lack of adequate skills. There is a huge skill gap behind jobless engineers and the question arises how we can prepare engineers for a better tomorrow? Now a day's Industry 4.0 is a new fourth industrial revolution which is an intelligent networking of machines and processes for industry through ICT. It is based upon the usage of cyber-physical systems and Internet of Things (IoT). Industrial revolution does not influence only production but also educational system as well. IoT in academics is a new revolution to the Internet technology, which introduced "Smartness" in the entire IT infrastructure. To improve socio-economic status of the India students must equipped with 21st century digital skills and Universities, colleges must provide individual learning kits to their students which can help them in enhancing their productivity and learning outcomes. The major goal of this paper is to present a low cost, effective learning mechanism for STEM implementation using Raspberry Pi 3+ model (Single board computer) and Node Red open source visual programming tool which is developed by IBM for wiring hardware devices together. These tools are broadly used to provide hands on experience on IoT fundamentals during teaching and learning. This paper elaborates the appropriateness and the practicality of these concepts via an example by implementing a user interface (UI) and Dashboard in Node-RED where dashboard palette is used for demonstration with switch, slider, gauge and Raspberry pi palette is used to connect with GPIO pins present on Raspberry pi board. An LED light is connected with a GPIO pin as an output pin. In this experiment, it is shown that the Node-Red dashboard is accessing on Raspberry pi and via Smartphone as well. In the final step results are shown in an elaborate manner. Conversely, inadequate Programming skills in students are the biggest challenge because without good programming skills there would be no pioneers in engineering, robotics and other areas. Coding plays an important role to increase the level of knowledge on a wide scale and to encourage the interest of students in coding. Today Python language which is Open source and most demanding languages in the industry in order to know data science and algorithms, understanding computer science would not be possible without science, technology, engineering and math. In this paper a small experiment is also done with an LED light via writing source code in python.

Disasters, including earthquakes and landslides, have enormous economic and social losses besides their impact on environmental disruption. Iran, and particularly its Western part, is known as an earthquake susceptible area due to numerous strong ground motions. Studying ecological changes due to climate change can improve the public and expert sector's awareness and response to future disastrous events. Synthetic Aperture Radar (SAR) data and Interferometric Synthetic Aperture Radar (InSAR) technologies are appropriate tools for modeling and surface deformation modeling. This paper proposes an efficient approach to detect ground deformation changes using Sentinel-1A. The focal point of this research is to map the ground surface deformation modeling is presented using InSAR technology over Sarpol-e Zahab on 25^th November 2018 as a study case. For surface deformation modeling and detection of the ground movement due to earthquake SARPROZ in MATLAB programming language is used and discussed. Results show that there is a general ground movement due to the Sarpol-e Zahab earthquake between -7 millimeter to +18 millimeter in the study area. This research verified previous researches on the advanced image analysis techniques employed for mapping ground movement, where InSAR provides a reliable tool for assisting engineers and the decision-maker in choosing proper policies in a time of disasters. Based on the result, 574 out of 682 damaged buildings and infrastructures due to the 2017 Sarpol-e Zahab earthquake have moved from -2 to +17 mm due to the 2018 earthquake with a magnitude of 6.3 Richter.

One of the important elements for improving academic achievement of learners in education through e-learning is to support learners to study by finding questions they want with providing various evaluation questions. However, most of question retrieval systems usually depend on keyword search based on only a syntactical analysis and/or a hierarchical browsing system classified by the topics of subjects. In such a system it is not easy to find integrative questions associated with each other. In order to improve this problem, in this paper we proposed a question management and retrieval system which allows users to easily manage questions and also to effectively find questions for study on the Web. Then, we implemented a system that gives to access questions for the domain of C language programming. The system makes it possible to easily search questions related to not only a single theme but also questions integrated by interrelationship between topics and questions. This is done by supporting to be able to retrieve questions according to conceptual interrelationships between questions from user query. Consequently, it is expected that the proposed system will provide learners to understand the basic theories and the concepts of the subjects as well as to improve the ability of comprehensive knowledge utilization and problem-solving.
