  • The aim of this study was to examine how analogical mapping articulation activity played a role in solving process in word problems. We analyzed the problem solving strategies and processes that the participating thirty-three 8th grade students employed when solving the problems through analogical mapping articulation activities, and also the characteristics of the thinking processes from the aspects of similarity. As a result, this study indicates that analogical mapping articulation activity could be helpful when the students solved similar word problems, although some of them gained correct answers through pseudo-analytic thinking. Not to have them use pseudo-analytic thinking, it might be necessary to help them recognize superficial similarity and difference among the problems and construct structural similarity to know the principle of solution associated with the problematic situations.

  • To analyze a room reverberation, many objective parameters have been suggested as measures of subjective perception in concert hall acoustics. However, it is difficult to understand the relationship among the individual parameters and to have a whole image of them. In this paper five primary objective parameters were selected and a reverberation model based on them was established by the reverberation decay curve. The proposed model was interpreted geometrically in terms of subjective characteristics. And finally we discuss the usefulness and the limitation of the model when it is applied to the analysis and.

  • This paper presents the proposed methods of DE (distinct element) modelling to estimate the stability of tunnels in jointed rock masses. First, the criterion to select the joint set(s) contributed to the discontinuous behaviour in a tunnel section is proposed. Selected joint set(s) is(are) considered to form the edges of distinct elements (rock blocks) and the others to modify the elastic properties of rock blocks. The complex DE model with the average and the deviation of joint orientation and joint length for each joint set was compared to the simple model with only the average of joint orientation and the assumption that joint length is infinite. As a result, the latter is suitable to the purpose of tunnel design because it can show the consistent behaviour of a jointed rock mass such as the locally discontinuous failure and the global anisotropic behaviour.

  • This study analyzed the relationship among the construct level of analogical reasoning, prediction and uncertainty, and the construction of an explanatory model that were produced during small group discussions for scientific problem solving. This study was participated in by 8 students of K University divided into 2 teams conducting scientific problem solving. The participants took part in discussions in groups after achieving scientific problem solving individually. Through individual interviews afterwards, changes in their thinking through discussion activities were looked into. The results are as follows: The analogy at the Entities/Attributes level was used to make people clearly understand the characteristics of certain objects or entities in the discussions. The analogy at the Configuration/Motion level that was produced during the discussions ensured other participants to predict the results of problem solving. The analogy at the Mechanism/Causation level changed the structure of problem situations either to help other participants to reconstruct the explanatory model or to come up with a new situation that was never been through before to justify the created mechanism and through this, the case of creating Thought Experiments during the discussions were observed. if looking into the changes of analogies, each individual's analogic paradigm during the discussions were shown as production paradigm, reception-production paradigm, production-reception paradigm, and reception paradigm. The construction and reconstruction of the explanatory model were shown in analogic production paradigm, and in the reception paradigm of an analogy, participants changed their predictions or their certainty.

  • Classicism pursued beauty comprised of a perfect form, and beauty was perceived as a state of sufficiency. Accordingly, a completed and permanent beauty was sought after; as a result, a perfect and flawless form became the mainstream, and there was an effort to visualize the eternal proportional perfection. In classicism, forms were perfectly embodied with systematic inevitability and absolute inflexibility, by which an extremely clear aspect appeared. This study analyzes a classical construction paradigm in modern fashion according to the five categories: 'Harmony and order by numerical proportion', 'Clear form', 'Simplification of form and two-dimensional Seh-form', 'Completed contracture structure', and 'Pluralistic unification', and the respective formative characteristics are as follows. First, in terms of the formative aspect of modern fashion,'Harmony and order by numerical proportion' results from thorough observance of extreme and golden section (proportion of 5 :8) which was an aesthetic standard of beautiful body in classicism. Second, 'Clear form' appears in clothes as individual clearness of structural elements expressing each part of body, and shows a well-established form possible to be grasped with equal and clear contour line. Third,'Simplification of form and two-dimensional Seh-form' comes out as form composition, single line, single layer structure, two-dimensional form and arrangement of elements of clothes through the front viewpoint caused by 2D diagramming work while fashion-designing and producing. Also, it is seen that two-dimensional proportion which is composed of sections through various harmonious lines and sides according to the simple two-dimensional compatibility principle is accomplished. Fourth, 'Completed contracture structure' emerges as an expression of stationariness, in other words, fixation of an overall impression. This is a tendency that the overall form is grasped as a fixedly intact shape without a big change of the silhouette of clothes. Fifth, 'Pluralistic unification' means that it respectively emphasizes all the parts composing clothes by making them individually independent at the same time as each element is inclusively shown with the harmony of the overall silhouette of clothes and many other details. This study examined classical formative characteristics through a theoretical research on a formative paradigm revealing the classical style. Also, the significance of classical or rational value of art was illuminated by observing what characteristics a classical formation paradigm shows in modern fashion. As a result, classical characteristics in modern fashion prove that classicism is not a merely past construction style separated from the present but a construction paradigm deeply involved in our reason system.

  • There are various views in the boundary of deflationism of truth in regarding the nature and role of truth. This paper surveys the issue on how the core thesis uniting the deflationism is characterized. First, I will examine some comments on what is the central thesis supported or rejected by the deflationists and inflationists, mainly discussing Armour-Garb and Beall's work, and will show on which aspects they are unsatisfying. From this, I will suggest these statements: first, the central cores of deflationism are conceptual fundamentality and explanatory exhausting. Second, the particularity thesis, understood in an alternative way, cannot be a central claim of deflationism. Third, another important claim from deflationists, the expression thesis, can be derived from the two main thesis above. But it is still not clear enough what the non-expressive explanatory role of truth, which is denied by the expression thesis. So I will check some possible clarifications on it and discuss why they should be rejected. And I will introduce Dummett's view on the role of truth condition in truth conditional explanation of meaning, and I will claim that if Dummett is right why the role must be a inflated one. Finally, I will suggest a further implication that the understanding on the both sides can be widened by connecting considerations on both views.

  • The purpose of the study was to show the development process of the total instructional alignment based on the 2015 revised technology home economics curriculum, and to present the detailed aspects of this task. The results of this study were as follows: First, the clarity phase of the performance established the annual evaluation plan to ensure the consistency of the achievement standard, the learning objectives and the assessment objectives through an analysis of the curriculum. Second, the development phase of the performance tasks and the grading criteria analyzed the contents area and determined the performance assessment task. The performance assessment consisted of a portfolio and project activity types, and also comprised of knowledge markets, as well as e-NIE tasks, including individual tasks and collective tasks. Third, the performance assessment and the results phase were conducted after planning the class operation according to the instructors' directions and arrangement of the schedule into block classes. Afterwards, the performance assessment tasks were revised by the teaching-learning community and class reflection on practical application. As these results demonstrate, developing performance tasks that are centered on the learner's development processes can contribute to teachers' expertise and improvement of instruction.

Von der Differenzierung zwischen der kognitiven und ontischen Ununterscheidbarkeit (인식적 구분불가능성과 존재적 구분불가능성의 구별에 관하여)

  • Das Ziel dieser Abhandlung ist die Unterscheidung zwischen der kognitiven und ontischen Ununterscheidbarkeit. Jene zeigt sich als die Ununterscheidbarkeit, die aus dem Fehler des Identifizierens erfolgt. Diese besteht in der $Selbstidentit{\ddot{a}}t$ jedes individuellen Seienden. Um der Untersuchung der zwei Arten der Ununterscheidbarkeit willen soll die $Identit{\ddot{a}}t$ als Begrifflichkeit von dem Identifizieren als der subjektiven $T{\ddot{a}}tigkeit$ unterschieden werden. $W{\ddot{a}}hrend$ das kognitiv Ununterscheidbare nicht immer das Identische sein kann, ist das ontisch Ununterscheidbare notwendig das Identische. Durch diese Unterscheidung zwischen den beiden Konzeptionen der Ununterscheidbarkeit kann der Sinn des Leibniz'schen Satzes der $Identit{\ddot{a}}t$ des Ununterscheidbaren (principium identitatisindiscernibilium) deutlicher erhellt werden, indem diese Unterscheidung die kritische $Verst{\ddot{a}}rkung$ seines Satzes impliziert. Die Denkbarkeit der Duplikate, die intrinsisch $v{\ddot{o}}llig$ identisch qualifiziert sind, gilt als der bedeutsamste Einwand gegen seinen Satz der $Identit{\ddot{a}}t$. Aber der $Identit{\ddot{a}}tssatz$ - principium identitatis indiscernibilium - ist noch $g{\ddot{u}}ltig$, weil diese Duplikate letztendlich mittels der raumzeitlichen Relationsbeschaffenheit unterscheidbar sind. Hierdurch wird die grundlegende bzw. unentbehrliche Funktion der $Subjektivit{\ddot{a}}t$, die die raumzeitliche Relationsbeschaffenheit $erm{\ddot{o}}glicht$, $erl{\ddot{a}}utert$. $Daf{\ddot{u}}r$ wird Hegels $Erkl{\ddot{a}}rung$ vom $Identit{\ddot{a}}tsbegriff$ und Leibniz bearbeitet.
