Objective: We propose empathy as a user research method for service design. Background: We argue that empathy will enable user researchers to go beyond the conceptual knowledge to the design knowledge of user experience. Method: We tested our hypothesis by conducting an experiment in which subjects were required to propose solutions to improve the experience of a family member of a patient hospitalized in an emergency department. Results: We found that the subjects who empathized with the family member of a patient tended to suggest the solutions based on design knowledge rather than the solutions based on conceptual knowledge compared to the subjects who did not empathize. Conclusion: Data support our hypothesis that empathy enables people to focus on design knowledge rather than conceptual knowledge. Application: These findings provide practical implications for user researchers in service design.

Isik & K$_1$l$_1$c (1998: Mathematics Education and its Appraising in the Primary School Teacher Certificate) found that many prospective mathematics teachers for primary schools who attended at newly established certificate programs made significant misconception on mathematics education because they were not graduates of education faculties. The levels of conceptual knowledge and procedural knowledge of students from a secondary school in Erzurum, Turkey were investigated in order to reveal how serious misconception the teachers have been made so far. The conceptual knowledge is very important to students, however in this research, it was found that procedural knowledge was much more important than conceptual knowledge.

This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

이 논문에서 연구자는 중학생들의 수학 학습을 삼 년간에 걸쳐 관찰하면서 그들이 유리수 범위에서 형성한 개념적 지식과 절차적 지식 사이의 발달 관계에 대하여 조사하였다. 특히, 아래의 두 상황에서 학생들의 개념적 지식과 절차적 지식 사이의 불균형한 발달이 이후의 지식 발달에 어떤 영향을 미치는 지에 관하여 조사하였다: (a) 상대적으로 강한 개념적 지식과 약한 절차적 지식을 가진 경우; (b) 상대적으로 약한 개념적 지식과 강한 절차적 지식을 가진 경우. 연구 결과는 개념적 지식과 절차적지식이 균형적인 방식으로 (즉, 아주 근접하게 되풀이되거나 동시에) 발달될 때 가장 생산적이라는 것을 시사하며 또한 어느 한 가지 유형의 지식이 다른 유형의 지식보다 우위에 있다는 가정에 의문에 제시한다.

On the Semantic Web, the content of the documents must be explicitly represented through metadata in order to enable contents-based inference. In this study, we propose a mechanism to convert the Conceptual Graph (CG) into Resource Description Framework (RDF). Quite a large number or representation languages for representing knowledge on the Web have been established over the last decade. Most of these researches are focused on design of independent knowledge description. On the Semantic Web, however, a knowledge conversion mechanism will be needed to exchange the knowledge used in independent devices. In this study, the CG could give an entire conceptual view of knowledge and RDF can represent that knowledge on the Semantic Web. Then the CG-based object oriented PROLOG could support the natural inference based on that knowledge. Therefore, our proposed knowledge conversion mechanism will be used in the designing of Semantic Web-based knowledge representation and inference systems.

지능형 시스템은 자료나 정보보다 지식을 주로 이용하는 시스템이다. 따라서 지식표현은 지능형 시스템 구축에 있어서 중요한 요소이다. 개념그래프는 지식을 효율적으로 표현할 수 있는 그래프 형태의 논리적 지식표현 언어이다. 하지만 개념그래프를 직접 프로그래밍에 활용하기는 쉽지 않다. 이러한 어려움을 극복하기 위하여 여러 가지 도구들이 개발되었다. 본 논문에서는 개념그래프를 이용한 지능형 시스템 구축에 활용할 수 있는 도구들에는 어떤 것들이 있는지 조사하고 그들의 기능과 특성을 비교 분석한다. 조사결과는 지능형 시스템 구축을 위한 개념그래프 활용에 큰 도움이 될 것이다.

본 연구의 목적은 수학적 모델링 수업에서 학생들이 개념적 지식과 절차적 지식을 연결하는 방안을 탐색하는 것이다. 이에, 초등학생들이 개념적 지식과 절차적 지식을 연결하는 데 어려움을 보이는 학습 내용 중 최대공약수를 선정하고. 개념적 지식과 절차적 지식을 연결하면서 최대공약수 관련 문제를 해결할 수 있도록 수학적 모델링 수업을 설계하여 실행하였다. 분석 결과, 해당 수학적 모델링 수업은 학생들이 개념적 지식과 절차적 지식을 연결하여 문제를 해결하는 데 긍정적인 영향을 미친 것으로 나타났다. 또한 실제 수업 적용을 통해 수학적 모델링 수업에서 개념적 지식과 절차적 지식을 의미 있게 연결하기 위한 교수학습 방안을 도출하였다.

Conceptual and procedural knowledge of integration is necessary not only in calculus but also in real analysis, complex analysis, and differential geometry. However, students show not only focused understanding of procedural knowledge but also limited understanding on conceptual knowledge of integration. So they are good at computation but don't recognize link between several concepts. In particular, Riemann sum is helpful in solving applied problem, but students are poor at understanding structure of Riemann sum. In this study, we try to investigate understanding on conceptual and procedural knowledge of integration and to analyze errors. Conducting experimental class of Riemann sum, we investigate the understanding of Riemann sum structure and so present the implications about improvement of integration teaching.

This study investigated three preservice teachers' mathematical problem solving among hand-in-write-ups and final projects for each subject. All participants' activities and computer explorations were observed and video taped. If it was possible, an open-ended individual interview was performed before, during, and after each exploration. The method of data collection was observation, interviewing, field notes, students' written assignments, computer works, and audio and videotapes of preservice teachers' mathematical problem solving activities. At the beginning of the mathematical problem solving activities, all participants did not have strong procedural and conceptual knowledge of the graph, making a model by using data, and general concept of a sine function, but they built strong procedural and conceptual knowledge and connected them appropriately through mathematical problem solving activities by using the computer technology.
