The purpose of this study is to draw implications for the improvement in the CSAT by analyzing structures and tasks in the Abitur. To this end, it analyzes the mathematics test system with a focus on the basic and advanced level examination systems, the operator, the using technology, and mathematical formulas. And the characteristics of tasks in the 2021 Abitur were analyzed. As a result of the analysis, first, Germany evaluates whether students have the competency emphasized in the curriculum at Abitur. Second, Germany, which emphasizes the proper use of technology, utilizes both tasks that use technology and those that do not in the Abitur. Third, the Abitur consists of most of the tasks using promised operators and uses various types of operators to present various types of questions to evaluate competence. Fourth, the Abitur includes not only simple structured items consisting of 2-3 subtasks but also tasks dealing in depth with a single situation centered on a big idea. Finally, mathematical justification and proof play an important role in the Abitur. Based on this, some specific measures for improving the CSAT were suggested.

This study examined the effects of collocation-based instruction on L2 vocabulary acquisition and learners' interests in it. Fifty one students were randomly assigned to the experimental group (collocation-based instruction group) and to the control group. The participants' English vocabulary capacity was checked through pre and post tests, and two surveys were used to probe the learners' vocabulary learning behaviors and their interests in English vocabulary learning respectively. To better understand the participants' opinions and feelings on the collocation-based learning, follow-up interviews were also carried out. The results showed that second language (L2) learners' vocabulary capacity was significantly improved through collocation-based instruction. However, the participants' degree of interest in vocabulary learning did not reach our expectation partly because of external factors such as the Test for the College Scholastic Ability Test (CSAT) and lack of familiarity of collocations. Such results indicate that the high school students' rooted perception of putting importance on test-based language learning could not be easily changed since it is closely related to their immediate needs. Based on the results, this study suggested how to implement collocations into L2 classrooms effectively.

On the bases of the 5 principles and the 4 criteria for designing and developing of the listening and the reading test of National English Ability Test (NEAT), this study presents Item-Types Decision-Making Model as a blueprint for designing and constructing the two tests. It sets up the criteria for validating item types, designs a modular type of test specifications, constructs an item-types bank, and specifies a complementary type of test specifications of the two tests. To gather all these threads up, it constructs Item-Types Decision-Making Model which consists of such components as the item-type pool, the validity criteria and the procedures of testing item types, the item-types bank, the modular and the complementary type test specification. Thus, it shows how the Model works in developing and constructing the two level-differentiated listening and reading tests (the 2nd and the 3rd rank) of NEAT. Finally, it discusses some implications and applications of the Model to the two level-differentiated tests (the A and the B type) of 2014 CSAT (College Scholastic Ability Test) systems, National Assessment of Educational Achievement (NAEA), and classroom testing. In conclusion, Item-Types Decision-Making Model functions as a testing template in an item development system and as a matrix in an item-types bank system.

An enormous amount of efforts has been devoted to the development of finite elements for the bending problem of thick plates, especially based on Mindlin plate theory. Here, an approximate Constant Shear Angle Theory is usually used to take a transverse shear deformation of thick plate into consideration, which cannot be effectively considered the influence of transversal warping of cross-section with an increase of thickness. It might be the best way to represent the exact cross-sectional warping of the plate. The overall objective of this study is to develop a new formulation of plate including shear deformation and transversal warping, to perform extensive parametric studies comparing its results with those from Mindlin plate formulation, and to gain further insight into the influence of shear deformation and transversal warping of thick plate.

The purpose of this research is to analyze the recognition of the curriculum experts on 2015 integrated liberal arts and natural sciences curriculum revision. Research method is a delphi survey and the subjects are curriculum experts. The research results are as follows. Firstly, experts suggested common education for all students and students' opportunities to choose subjects. Secondly, the direction of curriculum revision was different by school level. The elementary school needs to foster convergence thinking. The middle school needs to educate common basic literacy education and the high school needs both the common education and the free choice of subjects by students. Thirdly, the separation of the liberal arts and natural sciences was caused by the separate thinking of custom, tradition and study and the separate exam application on liberal arts and natural science of college scholastic ability test. The solution about separation problem of liberal arts and natural sciences have been proposed to improve mathematics education and teachers' convergence education competency. Lastly, for the establishment of an 2015, integrated curriculum the reduction of the CSAT test area and the introduction of qualifying examination for English were required.

Current Mathematics of CSAT(College Scholastic Ability Test) faced with preparing the test system and test items according to the new curriculum. The discuss about how to construct the items and what form of items should be set was not conducted enough. To accord with these requirements, in this study, mathematics exams for university entrance in Taiwan are investigated. We look into General Scholastic Ability Test(GSAT) and Advanced Subjects Test(AST) in Taiwan. Those exams are analyzed in terms of exam system, mathematical contents, types of items, and so on. And then on the basis of this, we discuss implications on mathematics assessment type and contents, further mathematics learning.

In this study, the students' responses on the items of chemistry II in the College Scholastics Ability Test (CSAT) implemented for the past 3 years since 1999 was investigated. The number of applicants and mean score of chemistry II, average percent correct by contents and inquiry process, and the items with high and/or low percent correct are analysed and discussed. The percentage of applicants for natural science track is reduced each year. However, more than 25% of natural science track applied to chemistry II, which ranked second to biology II. The mean score of chemistry II was increased in 2001 along with those of other subjects. There is no difference in average percent correct either by contents or inquiry process. Students performed generally poor at solving test items relating to 'colligative properties of solution' such as 'boiling point elevation' or 'osmotic pressure', and very well at solving test items relating to 'reaction rates'. Educational implications are discussed.

The purpose of this study is to construct a structural equation model and to analyze causal relationships among variables related to attitudes to science using structural equation modeling(SEM) with LISREL VII. The sample consisted of 483 10th grade boys from a general high school in Pusan, Korea. The questionnaires (ABC-attitude scale: affection, behavioral intention, cognition scale of attitude towards science) were developed by the researcher through a pilot study. And other instruments have modified previous ones. Five instruments were used in this study: GALT(group assessment of logical thinking), MTSlS(modified test of science inquiry skill), ABC-attitude scale, MSAS(modified scientific attitude scale), CSAT(common science achievement test). Structural equation modeling with LISREL VII($J\ddot{o}reskog$ & $S\ddot{o}rbom,$ 1993) was employed to estimate the causal inferences about hypothesized relationships among observed data sets. Three competing models consisted of five latent variable(scientific thinking ability, science inquiry skill, attitude towards science, scientific attitude, science achievement) - lP(inquiry preceding) model, AP(attitude preceding) model and AM(attitude mediating) model - were developed. Among these competing models, IP model satisfied the observed data sets. The causal relationships among "attitudes to science" and other latent variables were reliably identified. According to the results of the present study, science inquiry skill was the most significant variable that can predict science achievement. But scientific thinking ability has not directly influenced science achievement. This study suggests that inquiry based teaching-learning processes should be offered to students for improvement of science achievement. At the same time, it seems to be important to develop positive attitude towards science. Understanding of relationships among variables related to attitudes to science will be helpful to the development of science curriculum and to the design of science teaching and learning process. LISREL has been recognized as a useful approach in testing a SEM. However, in this study, LISREL approach was estimated as much more useful method for research design.

Unlike Korean science curriculum's continued push for "relevance of contents" to reduce the burden of learning on students, IB DP (International Baccalaureate Diploma Programme) is chosen in many countries and the number of IB world schools continues to grow, although it contains not only a large amount of learning but a substantial amount of content that requires quantitative calculations. Through this study, we suggest implications for Korean science curriculum and textbook, by comparing the constructions of chapters, the achievement standards, the learning contents, and the formulas of physics textbook, focusing on the 'relativity' unit of the 2015 revised national curriculum and IB DP, and by analyzing the questions of college scholastic ability test (CSAT) and external assessment (EA).

Due to a lack of teachers and available classrooms, high school students are not able to take the elective courses of their choice. In order to solve this problem with online instruction, I have used the following methods: First, I conducted a literature study to examine the concepts and models of online instruction. Second, I compared the number of students who took the CSAT subject tests with the number of students who enrolled in optional courses through KEDI's Education Statistics Services. Using the data gathered from this comparison, I could predict the demand for each optional course. Finally, I proposed amending the Elementary and Secondary Education Act; the Enforcement Decree of the Elementary and Secondary Education Act; the General Statement Curriculum of High Schools; and the Guidelines for Recording School through the expert interviews for on-line instruction in order to establish online instruction for high school students.
