This study, through the cases occurred in mathematics pencil-paper test, after analyzing the types and the factors of misunderstanding, was to seek to pursue the alternatives to diminish the misunderstanding caused in paper test. When classifying misunderstanding shown in pencil-paper test, four types are found - unsuitable edit, unsuitable organization, formal/typical habits, and unsuitable question situation. One Way, considering accomplishment rate based on existence and nonexistence of misunderstanding factors, the testing paper, that is, type A with misunderstanding factors, showed that the accomplishment rate is 10 percent below the testing paper, type B excluding misunderstanding factors. Also, after distinguishing only items including misunderstanding factors, in comparison with the accomplishment rate, the results showed about 22% difference. And in the type of misunderstanding factor, when system was unsuitable, the degree of misunderstanding appeared seriously. The more complicated many types were, the higher the number of misunderstanding cases appeared. Based on these study results, the conclusions are the followings : First, teachers should try to develop examination papers for exact evaluation. Second, teachers, while students are solving the questions, misunderstanding recognize what are the misunderstanding factors they feel. Third, in the pencil-paper evaluation, the work that teachers should consider importantly, is to analyze students' thought process. Fourth, teachers should try for smooth communications with students.

The metropolitan and province offices of education have been enforcing the ICT application competence certification system for teachers(ACCST). But the system have been enforcing during 3years, the ratio of teachers that has been received certification of the system showed very low, and recently the number of applicant has decreased. The purpose of this study is to examine the problems of the system and to propose a method of improvement of the system. We surveyed literatures offering theoretical and empirical insights connected with this issue and derived suggestions for improvement of the system, and designed questionnaire based on the suggestions. Research data gathered from 547 Korean middle and high school teachers using questionnaire. The improvements on the certification system which can be drawn from this study should consider appropriation of incentive for teachers, introduction of certification method on individual subject, introduction of validation interval of certification, and commissioning in an external agency which has reliable the certification.

The aim of this paper was to diagnose Korean sixth graders' understanding for scientific evidence and explanation. The instrument constructed by Jeong, Songer, and Lee (2002) was used to assess students' understanding for priority of scientific evidence, objectivity of data, relevance of evidence, data interpretation, coordination of theory and evidence, and repeated observation. Results showed that although many students recognized certain features of scientific inquiry such as objectivity of data, few of them understood why such features are valued and how to collect and use such data. In particular, students experienced difficulty in formulating explanation from evidence, not knowing, for example, that repeated observations are needed before making a general statement. The results of this study suggest that efforts to foster students' inquiry abilities need to be based on careful analyses of students existing inquiry skills and understanding.

The aim of the study presented in this paper was to explore South Korean elementary teachers' knowledge regarding educational theory in mathematics. An independent t-test and ANOVA are applied to examine elementary teachers' knowledge regarding educational theory in mathematics. Findings of this study suggest that there is a negative correlation between the teachers' knowledge regarding educational theory in mathematics and their teaching experiences as well as the teacher certification level. However, there is a little affect of the teachers' gender and educational backgrounds on the teachers' knowledge regarding educational theory in mathematics. The results of this quantitative study may broaden our understanding of the South Korean elementary teachers' knowledge for teaching mathematics, which have a deep impact on their teaching practice.

Time is important in children's lives since their preschool years. However, previous studies indicate that many children struggle with the acquisition of time concepts. Also teachers do not know how to help them. This study aims to investigate elementary school students' understanding about time and induce its educational implications. To do this, about 130 children from first to fifth grades were tested for their ability to recognize(read and record) the analogue and digital times and to solve elapsed-time problems. The results showed that even first graders were able to read and record the minute times on digital clocks. And second graders were able to read and record the minute times on analogue clocks. Therefore, the ability to recognize analogue times was mastered by second grade. In case of the elapsed-time problems, there was statistically significant difference according to school years or types of problems. Students were successful in solving simple problems. However, the problems that include regrouping hour and minute remained difficult even for the older children. Based on these results, we made a few suggestions for teaching practice about time.

The purpose of this study was to analyze hierarchy for high school students' concepts about genetics. The assessment of genetics related concept was conducted for 10th and 11th grade students and a hierarchy map was schematized based on the evaluation result using Knowledge State Analysis Method. Some differences were found when comparing the result of whole students' hierarchy with hierarchy on 7th national science education curriculum. In analyzing hierarchy by grade, concepts of highest and lowest level turned out same but some concepts of middle level changed. In case of analysis of hierarchy for concepts about genetics by score, as score was higher, the number of concept in lower level became larger and the relationship among concepts became more structurized. Following studies are required to develop specific teaching strategies for having effective genetics concept and conduct case study of applying the concept hierarchy through this method to class in the field.

This paper is a study on the method to derive the functional level required for autonomous unmanned ground vehicle, one of the defense robots. Conventional weapon systems are not significantly affected by the operating environment, while defense robots exhibit different performance depending on the operating environment, even if they are on the same platform. If the performance of defense robot is different depending on operational environment, results of mission performance will be vary significantly. Therefore, it is necessary to clarify the level of function required by the military in order to research and develop most optimal defense robots. In this thesis, we propose a method to derive the required function level of unmanned ground vehicles, focusing on autonomous driving, one of the most vital functions of defense robots. Our results showed that the autonomous driving function depending intervention levels and evaluated functional sensitivity for autonomous driving of the unmanned vehicle using climate and topography as variables.

Objectives : The prevalence of allergic rhinitis (AR) is 10-40% worldwide and there are many demands for Traditionl Medicine (TM) treatment for AR. Pattern identification (PI) is essential process in diagnosis and treatment of TM, however, objective assessment measurement for PI of AR in TM is lacked. Methods : PI questionnaire for AR was developed in 2008 by specialists in the department of Otolaryngology of TM, based on systemic and nasal symptoms and signs. However, that questionnaire had many problems in application to clinical practice and has since been revised based on several studies and delphi method. Consequently, the PI questionnaire for AR version 3.0 has been developed. Results & Conclusions : This questionnaire classifies patients with AR as possessing lung-heat, lung-cold, or spleen qi deficiency based on nasal symptoms and general conditions of AR patients. This is first questionnaire for pattern identification of AR. We plan to conduct a validation and reliability study, and revise the questionnaire based on the results of this study.
