Based on the work of Haylock (cf [Haylock, D. W. (1987). A framework for assessing mathematical creativity in schoolchildren. Educ. Stud. Math. 18(1),59-74]) a mathematical creativity test containing items of two categories overcoming fixation and divergent thinking has been developed for Bengali medium school students with sample size 262. The items measuring divergent thinking are found highly internally consistent and there is a significant correlation between overcoming fixation and divergent thinking. Study of the factorial validity of the test by Thursstone's centroid method gives satisfactory result. Validity coefficient of the test with teachers' rating, alpha reliability and test-retest reliability of the test are also found satisfactory.

Test cases in the existing weapon system software were created manually by the tester analyzing the test items defined in the software integration test procedure. However, existing test case generation method has two limitations. First, the quality of test cases can vary depending on the tester's ability to analyze the test items. Second, excessive time and cost may be incurred in writing test cases. This paper proposes a method to automatically generate test cases based on the requirements model and specifications to overcome the limitations of the existing weapon system software test case generation. Generate test sequences and test data based on the use case event model, a model representing the requirements of the weapon system software, and the use case specification specifying the requirements. The proposed method was applied to 8 target models constituting the avionics control system, producing 30 test sequences and 8 test data.

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.

The study was to develop the instruments including instructional materials and test items for enhancing spatial ability. A mixed methodology was chosen to achieve the purpose of the study. To find students' achievement, 5 units of instructional materials were developed through the qualitative method and test items were tested through the quantitative method with 152 of the 8th-graders. The strategies to develop the instructional materials were: firstly to focus on mathematics properties for developing spacial ability; secondly, to allow students to follow hierarchical procedure o[ mathematical properties from 2-d to 3-d; thirdly, to recognize what the manipulative can do and can not; and fourthly, to guide students tn develop the process oriented thought, not the result oriented thought. For the test, 25 items were analyzed to assess students' achievement using validity, difficulty, and discriminator.

Background: Regional Cardiocerebrovascular Centers (RCC) were established for the prevention and treatment of cardiocerebrovascular disease and funded by the Ministry of Health and Welfare. The purpose of this study was to develop and validate the measurement tool of public benefits in RCC. Methods: Through the intensive literature review, experts surveys and their repetitive feedback, we selected the 46 items about the public benefits in RCC. Development of measurement tool involved content validity test using Content Validity Index (CVI), construct validity test through factor analysis and reliability test. Results: Thirty-five items were selected by content validity test, which CVI was 0.08 or higher. Through the construct validity test, 32 items in 7 factors were derived. And Cronbach's alpha was 0.951. Finally, public benefits measurement tool is composed of 32 items in 7 factors which are comprehensiveness of health care services, market complement, emergency care, cost, governance, quality improvement, and government control. Conclusion: Though we developed the measurement tool of public benefits in RCC, it would be utilized to measure the public benefits of various health agencies.

To investigate how personality test items are understood by participants, their semantic representations were explored by Latent Semantic Analysis, In this thesis, Semantic Similarity Matrix was proposed, which contains cosine similarity of semantic representations between test items and personality traits. The matrix was compared to traditional factor loading matrix. In preliminary study, semantic space was constructed from the passages describing the five traits, collected from 154 undergraduate participants. In study 1, positive correlation was observed between the factor loading matrix of Korean shorten BFI and its semantic similarity matrix. In study 2, short personality test was constructed from semantic similarity matrix, and observed that its factor loading matrix was positively correlated with the semantic similarity matrix as well. In conclusion, the results implies that the factor structure of personality test can be inferred from semantic similarity between the items and factors.

The purpose of this study was to develop a test tool for convergence problem solving skill. To this end, constructs of convergence problem solving skill were defined in three domains: convergence attributes, convergence thinking, and convergence literacy domains. Thirty-seven pilot items were developed on the basis of the sub-categories for each domain that was defined through intensive literature review; problem solving & convergent thinking and creative thinking for convergence thinking domain, individual and social propensity for the convergence attributes domain, and convergence literacy as convergence literacy domain. Through an exploratory factor analysis, 30 items in the constructs of the test tool were confirmed. A confirmatory factor analysis result showed that the five construct models well captured the covariance between all the items well. Finally a statistical result shows that the reliability of the items and constructs were well established (Cronbach's α value= .963). Thus, the test tool for convergence problem solving skill developed in this study was statistically reliable.
