There are a variety of evaluation methods used to evaluate and provide feedback to students, recognize shortcomings, and establish future plans. The purpose of the academic achievement evaluation is to check whether the student understands the content taught, identify areas that the student is unfamiliar with or misunderstand, and then provide supplementary study to prevent learning deficits. Multiple choice has been the evaluation system in Korea since the early 1970s, influenced by Tyler's goal-centered evaluation model that evaluates achievement of educational goals and Bloom's educational goal classification system. The most important item in education is the evaluation of whether you have properly understood the lesson and how deeply you know it. Therefore, in this study, in order to minimize cases where test takers stochastically answer the correct answer in a multiple-choice evaluation, the change in the standard deviation of grades was analyzed by applying a grading method that assigns negative points to incorrect answers. As a result of the study, it was found that the average score of the incorrect response evaluation was 1 to 4 points lower, and the standard deviation was wide. This showed that the test taker's discrimination ability was high in the wrong answer appraisal type.

The purpose of this study is to understand and compare the characteristics of the content organization system of three Environment textbooks currently used, and to examine its connectivity with the teaching & teaming methods included in the Environment subject part of the 7th Korean National Curriculum. For the analysis three Environment textbooks for middle school and their teacher's guide books by three companies. published(A, B, and C) The result of the taxonomic analysis showed that three Environment books had different steps to get to the lesson class unit in the way that A of six steps, B of five steps and C of seven steps. The amount of main text was different In the domains of'Human and Environment','Environmental Problems and its Counter-plan'and'Environmental Conservation'of three textbooks each. All of three textbooks had the biggest percentage in sub-domains of'Living Environment to Keep'and'Global Environmental Problem'in 'Environmental Problems and its Counter-plan'domain. Considering teaching & loaming methods all of three textbooks contained many activities as 55 in A, 66 in H and 91 in C. Among 9 teaching 8E teaming methods and others listed in the Environment subject part of the 7th Korean National Curriculum, the investigation method is most frequently used in all of three textbooks. The drama, the paly and the case study were used rarely as teaching & teaming methods in activities In the consideration of the content amount regarding academic fields, it was revealed that three textbooks overemphasized the aspect of natural sciences comparing the aspect of human & social sciences aspect as a whole. Generally the appendix section of all three textbooks were well organized to support the teaching and teaming activities in main text.

History of science (HOS, hereafter) has been considered as a useful tool for achieving a variety of objectives in science lesson. The purpose of this study was to develop three dimensional framework for effectively analyzing HOS content in science textbook. In addition, using this framework, we analyzed HOS content in science textbooks of the 7th curriculum by focusing on the history of Earth science. Developed framework consists of three dimensions; instruction context, role, and type. Each dimension has several sub-domains. The results of textbook analysis revealed that science textbook didn't include diverse HOS materials that are appropriate to three dimensions and its sub-domains of the framework. Based on the results, we proposed that three dimensional framework is an effective tool to develop materials for teaching and learning materials of HOS with multiple coordinations of various contexts and purposes.

The purpose of this research is to analyze content elements of Housing area in 2013 middle school Technology Home Economics textbooks 1 and 2, total of 22 according to 2009 revised curriculum. The analysis method was content analysis, focusing on contents of main text, tables & figures, reading material, and activity materials by their content elements. This research will contribute in obtaining suggestion for the post curriculum/textbook development and helping teachers to perform a lesson. The results are as follows. First, Housing area included 1 to 4 content elements per each units, from 2 chapters and 6 units. The content elements stated in Home economics curriculum were total of 16 which consists of 'the meaning of housing,' 'housing types,' 'family forms,' 'family life style cycle,' 'life style,' 'neighboring environment,' 'co-living values,' 'air environment,' 'heat environment,' 'light environment,' 'acoustic environment,' 'space division,' 'circulation', 'effective use of space,' and 'sustainable dwelling practice.' All of these components are dealt with in every textbooks. Second, the numbers of content elements provided in each textbooks were the same, however they showed difference in their contextual aspect. Some contents need supplemental material for their lacking content element. Others need proper understanding of the concept because some showed different contents from the appropriate content elements. Third, repetitions in content elements were observed, the contents of 'co-living values' in textbook 1 and 'sustainable dwelling practice' in textbook 2 were similar in terms of eco-friendly housing, co-housing and universal housing. These two content elements should be merged as one next curriculum, or should be stated together in one subunit.

The purpose of this research is to investigate how elementary school students execute sampling with what designs in order to gather information under a situation that requires collecting data and information about their household and everyday life, and to examine how they use tools, including table or graph, etc., in order to perform efficient analysis of data and information they surveyed, also what results they acquire. To test this, the researcher set up a situation in advance that requires collecting data, and, under this circumstance, the researcher instructed and guided school students to look for methods how to design and survey in order to gather data by having them discuss tasks, involving small groups or entire class, and seek its solutions by themselves through trial and errors. The results from surveys revealed that a lesson, which will have students do sampling and arrange statistical data and analyze the results, was possible to carry out in the class of 6th grade of elementary school.

In a EFL situation, most Korean students and teachers are exclusively dependent on English textbooks to acquire the cultural factors of English. Therefore, it is necessary to analyze cultural elements in the English Textbooks. The results of the study are as follows: First, although all of the textbooks contain the culture part at the end of each lesson, it is insufficient for students to build a cultural schema. Second, in the analysis of cultural types, three types of cultures are presented in a similar percentage. Third, the culture elements were analyzed based on the 7th national curriculum revised in 2011. The most dominant is the culture regarding arts and literature. Forth, in nationality analysis, universal culture takes up the largest portion. Therefore, it is required more efforts to improve students' knowledge of the American and English culture.

Flood is one of the major natural disasters affecting millions of people. Thailand also, frequently faces with this type of disaster. Especially, 2011 mega flood in Central Thailand, inundated highway severely attributed to the failure of national economic and risk to life. Lesson learned from such an extreme event caused flood monitoring and warning becomes one of the sound mitigations. The highway flood hazard mapping accomplished in this research is one of the strategies. This is due to highway flood is the potential risk to life and limb, and potential damage to property. Monitoring and warning therefore help reducing live and property losses. In this study, degree of highway flood hazard was assessed by weighting factors for each cause of the highway flood using Multi Criteria Analysis (MCA) based Analytic Hierarchy Process (AHP). These weighting factors are the essential information to classify the degree of highway flood hazard to enable pinpoint on flood monitoring and flood warning in hazard areas. The highway flood causes were then investigated. It was found that three major factors influence to the highway flood are namely the highway characteristics, the hydrological characteristics and the land topography characteristics. The weight of importance for each cause of the highway flood in the whole country was assessed by weighting 3 major factors influence to the highway flood. According to the result of MCA analysis, the highway, the hydrological and the land topography characteristics were respectively weighted as 35, 35 and 30 percent influence to the cause of highway flood. These weighting factors were further utilized to classify the degree of highway flood hazard. The Weight Linear Combination (WLC) method was used to compute the total score of all highways according to each factor. This score was later used to categorize highway flood as high, moderate and low degree of hazard levels. Highway flood hazard map accomplished in this research study is applicable to serve as the handy tool for highway flood warning. However, to complete the whole warning process, flood water level monitoring system for example the camera gauge should be installed in the hazard highway. This is expected to serve as a simple flood monitor as part of the warning system during such extreme or critical event.

The backward design suggested in the 2015 revised curriculum takes into consideration the consistency between a goal and its evaluation, and emphasizes the essence of knowledge. However, the method for designing lesson plans is different from those of the past and, as a result, teachers in the field have experienced some difficulty in applying the design. Accordingly, this study was aimed at examining the differences between the taxonomy of educational objectives with which teachers are familiar and the viewpoint of informatics. The result of the analysis indicated no difference when applying the hierarchy of the six-sided view of the concept of understanding, of which teachers felt some difficulty in terms of applying the backward design. However, the analysis did show some similarity to the hierarchy of the six levels suggested in the taxonomy of the educational objectives. In general, when a new theory is suggested, it is very difficult for it to be accepted and applied. This study holds significance in that it suggests that a new theory must be accepted on the basis of sufficient analysis along with the necessity of efforts to be dedicated in order to increase its applicability.
