This research presents a performance assessment system of which the purpose is to increase the effectiveness of the instruction and learning through the on-the-job superintendent of the instructor, the self-directed learning of the learner, and the interaction between instructors and students. The presented performance assessment system applies the problem-based situated learning of the web-based performance assessment to the production, the execution, the assessment, and the transmission of the test. For the effective administration and learning in the school, we applies the Problem-Based Learning of constructivism and the web-based situated learning of the learning community to the system design. The production of the web-based performance assessment shows that the problem-based and self-directed learning of the assessment are achieved through the web-based automatic production of the performance assessment, and the contextual learning by case-based learning is performed by the production of the template of the performance assessment.

The goal of this study is to suggest evaluation tools to assess computational thinking(CT) skills in primary robot-based programs. In addition, the researcher has expanded its evaluation approaches to include interpersonal competencies from the socio-cultural perspectives, not just focusing on intrapersonal competencies. In order to pursue the research goal, one-semester robots programs for the fifth graders were designed, and evaluation tools including a learners' CT competencies survey and a learning process monitoring rubric were developed. The results of this study are meaningful because it has expanded the evaluation approaches to connect to the concepts of CT and to include interpersonal aspects from the socio-cultural perspectives.

This study investigated the effect of accounting information on dividend policy as a measure of corporate conservatism from the perspective of the internal accounting management system. The verification is based on a sample of 543 companies listed on securities (excluding KOSDAQ and financial industry) among the Bank of Korea (2019) 「2018 Corporate Management Analysis」 and company analysis of the Korea Productivity Center (financial data disclosed as listed companies as a December settlement company) was composed. Using SPSS 22, empirical analysis was conducted using exploratory factor analysis and regression analysis. The first is the verification related to corporate conservatism and the role of dividend policy, and it is verification of whether internal accounting management influences financial decision-making. Second, if internal accounting management exists, it is a verification of how conservatism and investment policies (in-house reserve, debt borrowing, capital increase, dividends, etc.) affect the corporate value according to accounting information. As a result, from the perspective of the internal accounting management system, it was found that among the variables of accounting information, profitability can have a positive effect on corporate conservatism and dividend policy as a corporate valuation method of reinvestment. In addition, it has been proven that corporate conservatism has an effect on profitability-to-value through capital accumulation and reinvestment such as surplus and internal reserves. In the future, we will study and discuss the complementarity of corporate conservatism and dividend policy in relation to governance structure and improvement of the internal accounting management system.

Learner-oriented education and distance education based on Information & Communication technology are educational countermeasure to various demands of Information age. Especially Web has the characteristics of providing proper environments for implementing constructivism study theory. Yet, existing web-based evaluation system is implemented by HTML and Java script so it has low interaction and imperfect educational effects. Therefore, We evaluated students' study understanding ability of real-time distance education system and analyzed evaluation results to offer useful information for level study considering individual variation. In this thesis, with these results, we designed and implemented interworking and multimedia databank system without time and space limitations on Client/Server environment.

The purpose of this paper is to explain MacIntyre's critique of moral pluralism of modern society and reveal the limits of his critique of liberalism. It is a distinctive feature of the social and cultural order that we inhabit that disagreements over central moral issues are peculiarly unsettleable. Debates concerned with the value of human life such as those over abortion and euthanasia, or about distributive justice and property rights, or about war and peace degenerate into confrontations of assertion and counter-assertion because the protagonists of rival positions invoke incommensurable forms of moral assertion against each other. We usually call this situation 'modern moral pluralism' and concede as the natural outcome of the activities of human reason under free institution. But in After Virtue, MacIntyre vigorously criticizes modern moral pluralism. The main cause he took which brought about this state of affairs was the failure of 'the Enlightenment project'. According to MacIntyre, the Enlightenment project which has dominated philosophy for the past three hundred years promised a conception of rationality independent of historical and social context, and independent of any specific understanding of man's nature or purpose. But not only has that promise in fact been unfulfilled, the project is itself fundamentally flawed and the promise could never be fulfilled. In consequence, modern moral and political thought are in a state of disarray from which they can be rescued only if we revert to an Aristotelian paradigm, with its essential commitment, and construct an account of practical reason premised on that commitment. But one of the deepest difficulties with the argument of After Virtue is that the very extent of its critique of the modern world seems to cast doubt on the possibility of any realistic revival under the conditions of modernity of the Aristotelianism which MacIntyre advocates. Especially when we consider we are not only the characters found in our narratives but also we ourselves are the author of our own narratives. Moral pluralism is not seen as disaster but rather as the natural outcome of the activities of human reason under enduring free institutions.

The purpose of this case study is to get an implication on elementary pre-service teacher education programs by exploring how a pre-service teacher's noticing changes within a learning community. The pre-service teacher participated in a learning community with researchers. Data includes recordings and transcription of actual class and pre- and post discussion in the learning community, the pre-service teacher's reflection essays, field notes, and students' worksheets. Results are as follows. First, the pre-service teacher's attending moved from the result of tasks to students' mathematical thinking. Second, the pre-service teacher's interpretation changed from a lack of diversity and specificity of evidence to diversity and specificity. Third, the pre-service teacher's decision-makings changed from unproductive deciding to productive deciding.

In this study, we investigated the characteristics of the PCK components in the chemistry units of middle school science teacher's guidebooks developed under the 2009 Revised National Curriculum. The analysis of the results revealed that the sub-components of topic-specific strategies, vertical articulation, and lesson objectives were systematically handled in most teacher's guidebooks. However, subject-specific strategies, assessment methods, and curricular changes were mainly dealt with only in the general guidelines. Experiments and inquiries, assessment questions, and assessment dimensions were lack of constructivist approaches in the aspect of presented contents or forms. Horizontal articulation and knowledge of students were either lacked in relevant content or presented in the form of simple presentation. Concepts and theories accounted for the largest proportion of teachers' guidebooks, but some of them were beyond appropriate levels. On the bases of the results, the implications for the development of the teacher's guidebooks are discussed.

The purpose of this article is to examine the effects of item parceling on the consistency of significance testing of the causal parameters with regard to the relationship between the relevant constructs, as well as the effects of the item parceling on the goodness-of-fit indices of LISREL's general models. Most of the researchers' major purpose of using structural equation modeling (SEM) is to test their research hypotheses associated with the causal parameters. Therefore, we investigated three general models of LISREL, rather than the frequently used confirmatory factor analytic (CFA) models by many other researchers. The results of the study showed that there was a high level of consistency in the calculated test statics of causal parameters between the item-parceled solutions and the item-level solutions, and that the item-parceled solutions had better goodness-of-fit indices, such as GFI, AGFI, CFI, and NFI, than the solutions at the item level. However, in terms of RMSEA, there was no such tendency.

e-러닝의 활용도와 역할이 커져 가면서, 온톨로지(Ontology)나 컨셉맵(Concept Map)을 이용하여 e-러닝의 학습효과를 높이는 방안들이 연구되고 있다. 그러나 아직까지 e-러닝에 온톨로지나 컨셉맵 개념을 적용한 연구 사례는 미미한 수준이며, 이들간의 연계에 대한 고려 없이 별개의 대상으로 다루어져 왔다. 본 연구는 온톨로지와 컨셉맵의 상호 연관 관계와 각각의 장점들을 분석하여 학습에 있어서 시너지(Synergy)를 가져올 수 있는 새로운 e-러닝 시스템 구축 방안을 제안한다. 제안 시스템에서 온톨로지와 컨셉맵 간의 연계는 컨셉맵 에이전트에 의해 이루어진다. 컨셉맵 에이전트는 학습자의 수준이나 관심영역(주제와 범위)에 맞게 온톨로지로부터 추출한 학습 콘텐츠를 재구성해 준다. 학습자는 제안 시스템의 사용자 인터페이스를 통해 자신이 이해하고 있는 지식을 컨셉맵 형태로 표현할 수 있고, 컨셉맵 에이전트에게 요청하여 제공 받은 모범답안 컨셉맵과 자신이 표현한 컨셉맵을 비교하여 학습자가 스스로 자기 평가를 할 수 있다. 본 e-러닝 시스템이 제공하는 이러한 새로운 형태의 학습 환경은 학습자가 학습 지식에 대해 보다 체계적으로 접근하여 효과적으로 학습할 수 있게 해준다. 또한, 학습에 있어서 컨셉맵을 이용하므로 학습 형태의 특성상 보다 원천적으로 암기 위주의 학습에서 탈피하여 구성주의적인 학습을 가능하게 한다.

The goal of this study is to assess the effects of Scratch programming classes on preservice teachers by using computational thinking and cognitive evaluations based on Bloom's taxonomy. To pursue this research goal we measured preservice teachers' programming skills using cognitive evaluation items based on Bloom's taxonomy after preservice teachers took one-semester Scratch programming course. In addition, a survey focused on computational thinking (CT) concepts, CT practices, and CT perspectives was conducted. We also conducted artifact-based interviews to unpack preservice teachers' experiences of working on team projects and analyzed their experiences qualitatively. The results of this study are meaningful because we assessed preservice teachers' experiences comprehensively with both quantitative and qualitative methods. In addition, this study provides us with implications for evaluation perspectives in designing programming courses for preservice teachers by adopting Bloom's taxonomy scheme.
