The purpose of this study is to figure out the application of perceived quality and authentication evaluation system of teaching materials and implements for children in the early childhood education field. To achieve this, a survey was carried out from April 20 to April 30, 2013 on 150 guidance teachers who teach children classes for more than 3 years at kindergartens in Daejeon area, Chungnam. The results of the analysis are as follows. First, for the use of teaching materials and implements, 96.1% of teachers thought the quality of teaching materials and implements in their interaction with children was important. Most of them had a high perception of the quantity and quality when using teaching materials and implements with early childhood curriculum. For the most inconvenience when using teaching implements, developmental appropriateness was the highest by 47.3%. And the convenience of the application to children was 3.54 points on average. Above this, the application of teaching implements to children when using play and teaching implements was useful by 3.89 points on verage. The current teaching materials and implements for children in the early childhood education field was normal by 3.29 points on average. Second, teachers' perception of teaching materials and implements was relatively positive by 3.99 points on average, proving that the quality of teaching materials and implements based on the application of teaching materials and implements to early children in kindergartens was very important. Consequently, considering the importance and usefulness of teaching materials and implements, it is necessary to introduce institutional policies that teaching materials and implements with quality standard and institution evaluation can introduce the evaluation authentication system to guarantee the convenience of children' safety and use by the supply of quality-guaranteed products.

This study is a basic study to effectively develop a mathematics experience object, an important tool and educational tool in mathematics education. Recently, as mathematics education based on action theory is emphasized, various mathematics experience objects are being developed. It is also used through various after-school activities in the school. However, there are insufficient cases in which a mathematics experience teaching tools is developed and used as a tool for explaining mathematics concepts in mathematics classrooms. Also, the mathematical background of the mathematics experience teaching tools used by students is unclear. For this reason, the mathematical understanding of the toolst for mathematics experience is also very insufficient. Therefore, in this study, a development model is proposed as a systematic method for developing a mathematics experience teaching tools. Also, in this study, we developed 'the Great Common Divisor' mathematics experience teaching tool according to the development model. Through the model proposed through this study and the actual mathematics experience teaching tool, the development of various tools for mathematical experience will be practically implemented. In addition, it is expected that various tools for experiencing mathematics based on mathematical foundations will be developed.

The 7th curriculum sets a basic direction based on learner centered teaching. To this end, the curriculum puts a focus on activity centered classes using teaching tools. In reality, however, elementary school teachers find using the teaching tools in their classes difficult, although there are various studies going on to improve the practical use of the teaching tools in the classroom. In this paper, we present an effective approach to utilize those prior studies on using the teaching tools in classes for 4th, 5th and 6th graders.

The purposes of this study were to investigate teachers' perceptions on process-focused mathematics assessment using manipulatives and technological devices and to propose the direction of the process-focused mathematics assessment. This study was conducted by the survey method with a total of 332 elementary and secondary school mathematics teachers working in Seoul or Gyeonggi areas who had experienced in using manipulatives and technological devices. According to the results, the use of manipulatives and technological devices in the process-focused mathematics assessment will facilitate the use of various alternative assessment methods such as research-report, project, and discussion for the process-focused mathematics assessment. Those alternative assessment methods enable teachers to diagnose students' learning in more accurate and holistic views and contribute to improving teachers' teaching practices focused on the mathematical process.

As robots are proved to be effective in enhancing students' creativity and problem-solving abilities and satisfying various needs in special education for the gifted, many students participate in private education and after-school robot classes. However, it is difficult for students in the lower social economy class to use robots for their learning because of the high expense of robots. On this point, as a part of u-Learnng project, this research attempts to provide students in the lower social economy class with the opportunities to use robots for one year. At the end of the year, we will compare the experimental group and the control group in order to examine learning effects of using robots. Until now we have found many cases that show positive effects of the use of robots in students' learning.

The purpose of this study is to suggest didactical principles for using mathematical teaching aids and to applicate didactical principles in a relation with curriculum. First, we meta-analyzed related literature to suggest didactical principles for using mathematical teaching aids. And we suggested didactical principles as follows: principle of activities, principle of instruments, principle of learning. Using mathematical teaching aids with didactical principles in mind would help avoiding situations in which mathematical teaching aids are only used as interesting tools. Second, we concretized the meaning to applicate didactical principles and use mathematical teaching aids in a relation with curriculum. We considered domain, key concept, function, achievement standard, which were presented in the curriculum of mathematics, and suggested concrete activities. Third, we produced two designs for lessons on incenter and circumcenter of triangle and linear function's graph using mathematical teaching aids.
