This paper analyzed 20 teaching practices of elementary mathematics lessons which were recognized as effective instruction by the local educational offices throughout Korea, using an analytic framework with 4 main domains (i.e., curriculum and content, teaching and learning, classroom environment and atmosphere, and assessment) and a total of 44 sub-elements. The results of this study showed that the lessons focused on the key mathematics concepts according to the national mathematics curriculum and learning objectives, managed students in terms of shared rules within each classroom, and evaluated students' understanding of the concepts at the end of the lesson. However, the lessons did not foster students' calculation skills and only partly used either technology or game. Building on the related studies, this paper included implications of implementing high-quality mathematics instruction.

The Ministry of educational science and technology is about to conduct its 7th &8th curriculum. However, there are some problems in achieving its goals under the current class model system in both educational and architectural. This study finds the characteristics of the arrangements and architectural planning in the departmental system - designed high schools. As a result, the arrangement was tend to be 'overall type' or 'central type' depending on the teaching-learning efficiency. Liberal arts and science&technology groups were placed close, and foreign languages and general cultural studies were arranged close as well. Importantly, there were supporting facilities such as a gymnasium, a cafeteria, a library, a computer lab, and an all-purpose-room, and this arrangement provided convenience. It is for the better learning effect and the high efficiency. It is worthy noticing that the placement and formation of individual or study space is regarded importantly. In flow planning, it seemed that it was designed to reduce the users' movement to a minimum. However, there are still some problems compared to Japan or the States, who already has an established departmental system. I think that the government should enforce its necessity of planning to schools, relevant divisions, or architects to bring it up. Furthermore, it is urgently needed a practical and future-oriented study that can forecast any changes in architectural spaces within the ever-changing teaching and learning environment in the information-oriented society.

The aim of the National Assessment of Educational Achievement (NAEA) is to produce specific and reliable resources required for the diagnosis and quality control of teaching and learning by measuring the level of students achievement based on the national curriculum. In 2002, we introduced ‘modified Angoff Method’ to obtain more systematic and rational results about the achievement levels. The result indicated the differences of achievement level according to the differences of sexes. Female students achieved higher scores than male students in Grade 6. Male students achieved higher scores than female students in Grade 9 and 10. Furthermore it disclosed a problematic phenomenon that students in small towns and rural areas showed significantly lower scores in all six sub-areas of Mathematics compared with students in metropolitan and cities. The results from the NAEA listed above could be used as the authentic data for improving national curriculum and teaching and learning methods, the establishment of educational policies, and many other areas.

This article is devoted to investigating young learners' understanding of elapsed time from socio-cultural perspectives. The socio-cultural perspective benefits to access and personalize mathematics learning as how to have a mathematical object to be able to realize signifiers with the help of many other mathematical words and mediators. In terms of the realization of signifiers, I analyzed performances on elapsed time tasks of students in Grades 3 (n=115) and interviewed focal students. Quantitative analysis on students' performance identified that students perform differently when the task provided with the analog clock signifier. It suggested that students might think in a different way upon the given signifier even for the same elapsed time, especially when given as the analog clock. Qualitative analysis on focal students' interviews visualized how the students' understanding were different by displaying individual realization trees on elapsed time. The particular location of the analog clock signifier on each realization tree provided a personalized explanation about low performance on the task with analog clock signifier. The finding suggested that the realization of a specific signifier could be a key point in elapsed time understanding. I discussed why a majority of students face difficulty in elapsed time learning indicated analog clock and the advantage of moving elapsed time strands to higher grades in the school mathematics curriculum.

Equity in mathematics education focuses on the relationship between social inequality caused by factors including culture and race. Equity in mathematics education has recently been recognized as one of the important issues of mathematics education and may provide grounds for setting the new direction of mathematics education for the future society. However, research on mathematics education equity in South Korea is still insufficient. The purpose of the paper is to provide implications for mathematics education research by reviewing the the literature regarding mathematics education equity. Focusing on 195 previous studies, I analyzed the significance of discussions on mathematics education equity in mathematics education, the concept of mathematics education equity, and research questions. In addition, I divided the previous studies into five categories based on their research questions: mathematics teachers, mathematics curriculum, mathematics classrooms, mathematics assessment, and socio-cultural environments surrounding mathematics classrooms. The analysis of the study are expected to provide implications in terms of new research questions and methods to domestic mathematics education researchers.

This study has its aim at suggesting new direction of our education to search different ways in housing contents by comparing the necessity perception and demands between teachers and students for housing contents in Technology Home Economics curriculum of middle school. To achieve this aim, I chose middle school teachers in charge of Technology Home Economics and male and female students who are in the first grade in high school in Ulsan. I sent e-mail, mail, and visited researcher to gather the data. I used SPSS +12 statistical package for frequency, percentage, mean, standard deviation, and t-test to analyze the data. Here is the result. First, In the part of application of living place, teachers had necessity perception in use and placement of furniture, and arrangement of objects. Students had necessity perception in the use and placement of furniture, the kind and choice of furniture. Also in the indoor environment and equipment part, both teachers and students had necessity perception in controlling of ventilation, temperature, and humidity. In the part of maintenance repair of housing, teachers had necessity perception in the need for maintenance management but students had necessity perception in house equipments and repair had high necessity perception Second, In housing-related general part, teachers demanded housing for elderly, disabled people, information about future housing and students demanded environmentally friendly living environment, housing for elderly, disabled people. In interior design part, teachers demanded in the expression of interior places through computer, the kind and characteristic of housing material and students demanded the way to reuse old furniture, kind and characteristic of housing material. In the part of housing preparation and occupation, teachers demanded the kind of housing-related occupation and students demanded the housing tax and the process of house purchase or concerned matter. Third, there were some difference of necessity perception and degree of demand between teachers and students. Teachers had higher necessity perception and demand in all part except in demand for housing equipment, maintenance, and environmentally friendly living environment.

With the development of artificial intelligence, society is moving to a different world. As a result, amid growing interest in artificial intelligence education, research on how to teach artificial intelligence is also being conducted more actively in Korea. However, a lot of research is being conducted around the upper grades of elementary school, and curriculum and programs for the lower grades are insufficient. Therefore, this study developed an artificial intelligence program for lower grades. Among them, it was developed focusing on artificial intelligence image recognition. It compares image recognition methods of people, animals, and computers, identifies the characteristics of fallen leaves, and helps them understand the image recognition process of artificial intelligence by classifying them according to the characteristics of fallen leaves. I hope this program will help elementary school students understand the image recognition principle of artificial intelligence in the future.
