An effective teacher community helps the participating teachers improve their instructional quality. This study reports a teacher community consisting of 15 elementary school teachers and one teacher educator. This paper analyzed 15 mathematics lessons in which the teachers implemented the five practices for orchestrating productive mathematics discussions by Smith and Stein (2018) based on the grade-specific discussions as well as the whole community's discussions. The results of this study showed that the overall levels of each practice either increased gradually or maintained at the highest Level 4, as mathematics lessons had been implemented. Specifically, the following practices were quite successful: setting goals for a lesson, selecting an appropriate task, anticipating student responses, and selecting student solutions. However, both sequencing and connecting student solutions were implemented at various levels. Monitoring student work tended to remain at Level 2 which included incorrect implementation of the practice. This paper closes with implications related to the skillful implementation of the five practices through a teacher community.

Online education is a new domain of learning that combines distance learning with the practice of face-to-face instruction utilizing computer-mediated communication. As technology continues to develop and the needs of teachers require better access to higher learning, online graduate degree programs can be a valid alternative. Some institutions in the United States have already offered graduate degrees in music education through the online distance learning. In this study, 8 accredited online graduate degree programs in music education were identified in terms of curriculum requirement, program requirement, and admission requirement. Online programs offer considerable benefits of convenience, while their drawbacks relates to the quality of learning, feelings of weaker interpersonal interaction. More researches need in order for online music programmers to achieve higher standards of instruction and to inform other disciplines in the fields of arts education and the performing arts.

Smart Learning has been introduced in the educational field recently and it has been used in various ways to improve the quality of education. This research is focused on smart learning contents development for settlement in the educational field. It has carried forward studying in smart learning contents development using storyline, which is a kind of application authoring tool. We analyzed previous studies related to smart learning and presented the characteristics of storyline and the process of content development. Furthermore, we developed the content of digit sorting in Information Life for 6th grade elementary students and applied it to the field to evaluate the educational effectiveness. Through experimental results, the mean difference between traditional activities instruction and instruction using smart learning content was not significant. Nevertheless it has been found the immediate feedback and repeating of activities using smart learning has had positive impacts for understanding, satisfaction and learning interest.

Most of a courseware evaluated negatively by short of instructional strategy to improve learning effects. Designing a courseware is a time-taking and challenging task. Therefore, a method is required that helps to easily design courseware that is effective to learning. This study proposed a method for designing and management courseware by utilizing a metacognitive strategy. We made a design the coursewase efficiently using concrete instructional model frameworks as metacognitive stragety and tried to improve the quality of courseware for learning effects. We applied our proposed method to teacher's college students in Korea who were taking the "Courseware Development" course. After analyzing it's effects, the responds can design courseware easily and monitor the design direction while their designing. Also, they can design the courseware systematically and implement detail instructional strategy by using concrete instruction model frameworks as metacognitive strategy. However, they were not easy to develop concrete instructional model frameworks at first and we need sharing it among the designers.

This study analyzed the contents of "Reading" textbooks for 1st-6th grades. The focus of the analysis was on philosophical thinking methods designed to help children to think for themselves. Following the analysis, methods were designed for the application of effective use of Philosophy in the elementary school curriculum. Analysis of works of children's literature in "reading" textbooks show patterns of logical, ethical and creative thinking. Therefore, "reading" textbooks can be used to help children to think philosophically. Five stages of discussion can be applied in the classroom; these are: establish the issues, outline the process of discussion, discuss the issues, evaluate and summarize the discussion, apply the learning to other subjects. Teachers can use philosophical thinking methods to improve the quality and quantity of instruction with various questions, having children express their opinions, interpreting their thoughts clearly, maintaining logical consistency, and evaluating the procedures and results of discussion. These methods can be used in the teaching-learning process in the elementary school to develop rich findings and meaningful communication.

In the policy management of the safety&health, the environment and the quality, the documentation of the management system is required in every international regulatory guides. In case of 3 level classification of the system documents, it generally will be identified such name as the manual, the procedure and the job instruction. Each document has the unique role and usage though, the job instructions, especially, would be developed to support the practical job worker. So, the job instructions should be reflect the latest know-how of the job-handling methods. And that, it should be used at any times by the practical job worker. This study is planned to survey the actual usage status of the job instructions of the domestic enterprises, and tried to suggest the effective way of maintaining the documents.

Baotu Spring Park, a must-visit place in Jinan, China, has been rated as the country's highest-level scenic spot by the Chinese government. However, social media that highly reflects public opinions tends to express a lower evaluation of Baotu Spring Park. Thus, this paper employs service design thinking methods to identify the problems of Baotu Spring Park and provide solutions from the perspective of visitors. Based on desk research, tourist behavior tracking, contextual interviews, and a customer journey map, it was found that the service gap of Baotu Spring Park lacks a unified and effective instruction system. Also, the activities, parking, and high-quality tourist souvenirs are deficient, and there is no online information delivery platform. Finally, five suggestions are made,-respectively:,- redesign the sign system, enhance the participation of tourists, redesign the tourist souvenirs and display space, offer parking areas and shuttle buses, as well as set up a dedicated application.

Text summarization is the task of producing a shorter version of a long document while accurately preserving the main contents of the original text. Abstractive summarization generates novel words and phrases using a language generation method through text transformation and prior-embedded word information. However, newly coined words or out-of-vocabulary words decrease the performance of automatic summarization because they are not pre-trained in the machine learning process. In this study, we demonstrated an improvement in summarization quality through the contextualized embedding of BERT with out-of-vocabulary masking. In addition, explicitly providing precise pointing and an optional copy instruction along with BERT embedding, we achieved an increased accuracy than the baseline model. The recall-based word-generation metric ROUGE-1 score was 55.11 and the word-order-based ROUGE-L score was 39.65.
