Mathematical symbolizing is an important part of mathematics learning. But many students have difficulties m symbolizing mathematical ideas formally. If students had experiences inventing their own mathematical symbols and developing them to conventional ones natural way, i.e. learning mathematical symbols via expressive approaches, they could understand and use formal mathematical symbols meaningfully. These experiences are especially valuable for students who meet mathematical symbols for the first time. Hence, there are needs to investigate how early elementary school students can and should experience meaningful mathematical symbolizing. The purpose of this study was to analyze students' mathematical symbolizing processes and characteristics of theses. We carried out teaching experiments that promoted meaningful mathematical symbolizing among eight first graders. And then we analyzed students' symbolizing processes and characteristics of expressive approaches to mathematical symbols in early elementary students. As a result, we could places mathematical symbolizing processes developed in the teaching experiments under five categories. And we extracted and discussed several characteristics of early elementary students' meaningful mathematical symbolizing processes.

As a method of providing lifelong educational opportunities to working professionals, some legal provisions allowing for the establishment and management of an entrusted education system linked with college and corporation was duly approved in 1994. According to the recent trend in the military organization, to provide higher educational opportunities to noncommissioned officers and warrant officers with the purpose of inspiring their spirit and improving military capabilities has been much increased. Professional soldiers such as noncommissioned officers and warrant officers have a lot of problems to continue their attendance at school because of regular military maneuvers, constant alert status and long-term outdoor military training. Even more serious problem is that the current curriculums and some departments in college are not concurrent with the present job specifications and the military specialties of the individual soldier as well. The purpose of this paper is, therefore, to introduce a newly revised educational model that provides more viable academic courses and curriculums to military professionals along with a proposal for the establishment and management of long distance educational system within barracks, utilizing the latest information and telecommunication technology.

This study is about the design of teaching assistant robots that helps elementary school teachers while giving lectures. It focuses on finding images which fits the role of teaching assistant robots, not merely suggesting several designs of robots that are just preferred by children. For this study, the qualities that satisfy the role of teaching assistant were studied by literature reviewing. These qualities were grouped and prioritized to arrange them as role images of teaching assistant robot, through questionnaire to teachers and student teachers. Using the role images and basic adjectives as standards, children performed the image mapping with the pictures of existing robots. This allowed us to find out how children accept the external features of each robot, and which external feature has to be used in order to reveal the role images. And taking form of workshop, children expressed their own images of a teaching assistant robot, a robot's height and location in classroom was surveyed. Based on these studies', three design guidelines of teaching assistant robot have been suggested.

This study identified essential areas of student satisfaction by presenting questions concerning each educational area. The measurement tool of this study was developed based on a literature review, and its validity and reliability were verified through qualitative research and exploratory and confirmatory factor analysis. To measure student satisfaction in university, we developed a tool comprising seven areas: curriculum and instruction; student advising, educational environment, student support, campus life, university image, and administrative services. A total of 54 questions were prepared, and 7 factors were derived. Cronbach's alpha was 0.970 for all questions and ranged from 0.70 to 0.93 for each factor. The results of the confirmatory factor analysis were GFI 0.830, CFI 0.916, TLI 0.910, RMR 0.047, and RMSEA 0.047, which confirmed the suitability of the research model. Moreover, the convergent validity showed that the questions in this tool consistently described the component areas. Therefore, the research tools developed in this study were found to be suitable for measuring student satisfaction.

In recent years, There is a growing demand for more instructional hours because of the shortage of classes required for the software education included in the 2015 Revised Practical Arts Curriculum of elementary schools. Therefore, the Korea Association of Information Education developed the Informatics Curriculums Standard Model from 2014 to 2016 to revise the next 2020 curriculum. However, the KAIE curriculum lacks linkages with secondary school informatics curriculum and is not composed of core concept-based achievement criteria so that teachers have a lot of difficulties in reconstructing and operating the KAIE curriculum. In this study, four core concepts of information ethics were selected by conducting Delphi survey focusing on the teachers of elementary schools. In other words, we selected the core concepts of the information ethics domain: internet etiquette, personal information protection, information life, and copyright protection. Also, we suggested 16 specific criteria for the core concepts.
