  • This study is to establish the domains and the standards of instructional evaluation on the teacher knowledge dealing with the knowledge of 'teaching and learning methods and assessment'. Especially, in this study, the instruction assessment standards are developed focused on the five types of mathematics competencies such as problem solving, communication, reasoning, connection, information and handling, which were emphasized in the mathematical curriculum revised in 2022. By the result, ten domains such as an instruction involving instruction goal and content, problem-solving competency, data treatment competency, learners' achievement level and attitude, communication competency, reasoning competency, connection competency, the assessment method and procedure based on the competency, the assessment tool development based on the competency, assessment result based on the competency were new established. According to those domains, the total 20 instructional evaluation standards were developed. This study is limited to consider the domain of 'teaching and learning methods and assessment' among the domains of teacher knowledge, while dealing with the elements of mathematics competencies in the standards. However, instructional evaluation standards reflecting these competencies should be developed in the other diverse domains of teacher knowledge.

  • The purpose of this study was to examine the effects of brand knowledge on evaluations of brand extensions in fashion market. Here, consumer knowledge toward the parent brand was based on the brand and on the company which introduced the brand. The brand extensions were classified into brand-name extension and corporate-name extension. For this study, questionnaires were administered to 700 single women in twenties. The questionnaires were designed to measure brand extension evaluations and brand knowledge in terms of familiarity, use experience and self-assessed knowledge, evaluations of the attributes and attitudes based on the brand and corporate. Employing a sample of 621 women, data were analyzed by t-test. Major findings of this study are summarized as follows; 1) The higher the level of brand knowledge such as brand familiarity, brand use experience and self-assessed brand knoil- edge was, the higher positive effects were on the evaluations of brand-name extension. Also, evaluations of brand attributes and brand attitude positively influenced the evaluations of brand-name extension. 2) The higher the level of corporate knowledge such as corporate familiarity and use experience of product manufactured by the company was, the higher positive effects were on the evaluations of corporate-name extension. Also, evaluations of corporate attributes and attitude on corporate positively influenced the evaluations of corporate-name extension. These results demonstrate that positive knowledges and affects on the parent brand are transferred to its extended product through categorization process.

  • Mathematics preservice teachers' Mathematical Content Knowledge ("MCK") includes not only knowledge for mathematics, but also academic knowledge for school mathematics and mathematical process knowledge. We can consider the items in PISA 2012 as suitable tools to assess process knowledge as well as mathematical content knowledge because these items are developed by competent international educational experts. Therefore, the responses to items with the low percentage of correct answers in conjunction with the mathematical contents were analyzed with focus on FMC. The results showed the reasoning competency in responses using the conditions of the problem and of understanding the conditions after reading the complex problems within the context (i.e. the reasoning and argumentation competency, and communication competency) requires improvements. Furthermore the results indicated the errors due to a lack of ability of devising strategies for problem solving. Based on the foregoing results, the implications towards the directions of the education for the preservice mathematics teachers have been derived.

  • Rule-based knowledge representHtion is, the most popular technique for ,storage and manipulation of domain knowledge in expert system. By the way, the amount of knowledge increases more and more in this representatiun technique, it, relationship becomes complex, and even its contents can be modified. This is the reason why rule-based knowledge representation technique requires a verification ,system which can maintain consistency and completeness of knowledge base. This paper is to propose a verification system for consistency and completeness of knowledge base to promote the efficiency and reliability of expert system. After verifying the potential errors both in structure and in semantics whenever a new rule is added, this system renders knowledge base consistent and complete by correcting them automatically or by making expert correct them if it fails.

  • The purpose of this study was to explore instructional objectives of 'Wise Life' based on Bloom's Revised Taxonomy of Educational Objectives. It was to extend understanding the 7th and the revised Wise Life 2007 as well. The written objectives of two curriculum of Wise Life were divided into two, the 'knowledge' dimension and the 'cognitive process' dimension based on Bloom's Revised Taxonomy of Educational Objectives. Major activity subjects presented in the 7th and the revised Wise Life 2007 were dominantly the basic inquiry activity types. It was found from this research that the 'factual' knowledge of the 'knowledge' dimension and the 'understand' of the 'cognitive process' dimension took a large proportion of the revised Wise Life 2007 objectives. The 'meta-cognitive' knowledge was increased. 'Remember' of the 'cognitive process' dimension was decreased and the high level objectives as 'analyze' and 'create', in the 'cognitive process' dimension was increased from the 7th to the revised curriculum. The 'factual' knowledge, 'conceptual' knowledge and 'metacognitive' knowledge were engaged with 'understand' and the 'procedural' knowledge were engaged with 'apply'. The 'meta- cognitive' were engaged with 'create' is the 'procedural' knowledge in the revised Wise Life 2007. 'Remember' was decreased. 'Create' was increased in the basic inquiry activities. It was analysed in zero percent of 'Observing', 'Investigating and Presenting', and 'Making'.
