There are various efforts to alleviate problems about the learning disabilities each year, however, the number of the learning disabilities has been increasing. Therefore, we need to consider and develop practical methods to help them. In this aspect, we review and examine previous research regarding the learning disabilities which are known to be general and comprehensive. Then we suggest math clinic as one of the methods to alleviate the problem. There are purposes of the math clinic. The first is to make a comprehensive diagnosis for basic (emotional, environmental, psychological) reasons as well as the learning anxiety; not only the lower achievement in learning. The second is to provide them suitable corrective programs which would help them to gain a better understanding about mathematics and a positive learning attitude. The third is to provide them applicabilities in their learning and potentialities so that we have given them foundation in mathematics. In this article, we operate math clinic for the learning disabilities, and then make an analysis of the student's error occurred in learning, and finally we suggest a demonstrative operating program of math clinic for learning disabilities.

In this paper, we implemented memristor emulator circuit on Printed Circuit Board (PCB) and observed the inherent pinched hysteresis characteristic of memristors by measuring the emulator circuit on PCB. The memristor emulator circuit implemented on PCB is composed of simple discrete devices not using any complicated circuit blocks thus we can integrate the memristor emulator circuits in very small layout area on Silicon substrate. The programmable gain amplifier is designed using the proposed memristor emulator circuit and verified that the amplifier's voltage gain can be controlled by programming memristance of the emulator circuit by circuit simulation. Threshold switching is also realized in the proposed emulator circuit thus memristance can remain unchanged when the input voltage applied to the emulator circuit is lower than VREF. The memristor emulator circuit and the programmable gain amplifier using the proposed circuit can be useful in teaching the device operation, functions, characteristics, and applications of memristors to students when thet cannot access to device and fabrication technologies of real memristors.

Some studies require sufficient amount of time, spaces, and financial condition for practical exercises and training. In particular for the Medical education, time and space limitation is very high and difficulties occurs, since the practices are done with cadavers (deceased human body). Many alternate 3D Virtual surgery training system exist currently, however the burdensome of obtaining those costly equipments is problematic. Providing the surgical environment as similar to real as possible using 3D Virtual Reality can be a solution to current problems. The effectiveness of training could be maximized with minimized costs without the general interfaces such as keyboard and mouse, but with Oculus Rift and Leap Motion. This paper will develop and practice the 3D Virtual Operation System with two devices to investigate the possibility and expand to other Simulation fields.

Given the growing agreement that algebra should be taught in the early stage of the curriculum, considerable studies have been conducted with regard to early algebra in the elementary school. However, there has been lack of research on how to organize mathematic lessons to develop of algebraic reasoning ability of the elementary school students. This research attempted to gain specific and practical information on effective algebraic teaching and learning in the elementary school. An exploratory qualitative case study was conducted to the fourth graders. This paper focused on the associative law of the multiplication. This paper showed what kinds of activities a teacher may organize following three steps: (a) focus on the properties of numbers and operations in specific situations, (b) discovery of the properties of numbers and operations with many examples, and (c) generalization of the properties of numbers and operations in arbitrary situations. Given the steps, this paper included an analysis on how the students developed their algebraic reasoning. This study provides implications on the important factors that lead to the development of algebraic reasoning ability for elementary students.

One of the main objects of geometry in mathematics education is to improve students' geometric intuition capability and logical reasoning capability based on them. A visual element related to intuition plays an important role in teaching and learning of geometry. Therefore, in this research, we focus on the development of multimedia title available to dynamic operation about visual elements and verify of effect of its application. This title for the learning of "the Pythagorean theorem and its practical use" in the third grade of middle school is designed and implemented by an authoring tool, Toolbook. And it enables learners to study mathematics individually and can be applied to the educational field, too. And we taught two groups, the applied group and the compared one of the second grade of middle school and surveyed Questions and evaluated study achievement. We calculated study achievement of two groups on t-test using SPSS. As the result, we knew that the applied group is higher than the compared one in the study achievement and provision of dynamic operation possibility on visual elements make students know very high learning effect and help improvement of intelligent capability.

Forestry education in vocational high schools is one of the fundamental keys for achieving sustainable forest management. However, support systems for forestry education have not been well developed in Japan. Forest research institutes, which have accumulated relevant information, should have sufficient ability to develop new educational programs in this field. This study examined the possibility of support systems for forestry technical education by a research institute. Educational programs for vocational high schools were developed, and the programs were examined for their practical applications through a workshop for these teachers. We set the following five requirements for the programs: They should 1) incorporate new contents related to sustainable forest management, 2) be based on forestry education textbooks, 3) meet recent demands of the schools and society, 4) allow participants to learn through actual practice and experience, and 5) utilize readily available teaching materials. With these criteria, we developed the following two educational programs: (a) Forest management program to teach advanced techniques, (b) A timber-program to teach about biomass resources. The workshop was held on July $28^{th}$, 2007 with ten teachers attending. The programs were very interesting, who gave them high average evaluation of 4.6 on a scale of 1 to 5. Only a few issues need to be resolved before classroom instruction can begin, such as making wood structure easier to understanding for some teachers, and obtaining base maps of school forests. In conclusion, forest research institutes can effectively support forestry education by providing and implementing programs based on scientific information.

Teacher quality is a topic of international concern, as it impacts student learning and teacher preparation. This study compared the undergraduate secondary science teacher preparation programs from two universities in Korea with those of Oregon, USA. We examined the programs' structural curricular coherence, conceptual curricular coherence, and curricular balance. Structural curricular coherence was determined by examining the overarching goals of the institutions' programs, the organization of the programs of study in terms of meeting those goals, and outside bodies of evidence. All universities were in structural coherence for various reasons. Conceptual curricular coherence was determined by examining students' perceptions of the connection between their preparation and their clinical practice. In case of Korea, most students from both universities were not satisfied with their practical preparation. In the US, the students from both institutions felt well prepared to transition to inservice teaching. To determine curricular balance, we examined the institutions' preparation programs looking at the credit hours taken in the four main areas of the teacher knowledge base: GPK (General Pedagogical Knowledge), SMK (Subject Matter Knowledge), PCK (Pedagogical Content Knowledge), and CK (Contextual Knowledge). The total credit hours taken in each category was very similar by country but the application and field component in the USA was far greater than those of Korea where the focus was heavily on SMK and PCK. The main reason for these may be the nations' licensing and employment processes.

The purpose of this study was to present the activating schemes of nutrition education in elementary school curriculum. We examined the nutrition education status and perception of teachers on nutrition education in elementary school. This study was carried out using a self-administered questionnaire and subjects were 263 elementary school teachers in Gyeonggi province. All data in this research was analyzed through SAS program, and the frequency and percentage on each question were calculated. Data for each group was analyzed according to sex and teaching career and the groups were treated for significance by using chi-square test. Most of teachers taught the nutrition education as a part of practical In curriculum and thought that student's interest and participation on nutrition education was high. And the teachers understood that nutrition education at school curriculum is very necessary and effective. But most teachers had no experience or teacher training Program for nutrition education. They thought it was difficult to carry out nutrition education in school because of their poor nutritive knowledge, and lack in educational materials. Moreover, it is revealed that the teachers supposed that the activation of nutrition education in school requires schools to provide nutritive guidance to students in cooperation with the homes.

The purpose of this study was to emphasize the household financial education as a part of family life education, especially when provided at local community level; it also examines diverse measures by which to deliver such education. To this end, the current study focuses on the education programs of a healthy family support center, which has been established as a representative transmission system. The current status of its operations was examined, and practical measures by which to stimulate the delivery of financial education within that center were derived. In more detail, previous studies inside and outside of Korea were examined, and the current status of financial education included in the area of family life education was assessed; as a result of these assessments, the definition and objectives of financial education as family life education were adjusted. The limits of financial education that has been delivered thus far were reviewed, with the aim of proposing measures by which to sufficiently stimulate the delivery of financial education programs-programs that ultimately reflect the healthy family philosophy. This study proposes four specific measures by which to stimulate financial education. The first is the application of 'life cycle perspectives' to educational terms. The second is the activation of financial education programs that involve the family unit as educational subjects. Third, the delivery of lectures which related to the financing and nurturing of program coordinators was proposed. The fourth is drawing a connection between online and offline education in terms of effectively applying teaching methods. Ultimately, the results of this study can be used as basic data to inform the planning, development, and operational stages of financial education programs within family life education, which can be performed in healthy family support centers in the future.
