This study was designed to assess the developmental sequence of children's understanding of social interaction and to test the effects of support conditions and behavioral domains on the understanding of social interaction. The subjects were one hundred 4- to 8-year-old children. The method was a doll play situation, composed of three different support conditions. Scalogram analysis was used to test the developmental sequence, and ANOVA and paired t-test were used to test the significance of differences in stages. The results of this study evidenced a sequential pattern in the 4- to 8-year-old children's understanding of social interaction. There were also significant differences between stages in the understanding of social interaction according to support conditions and behavioral domains. Higher levels of support produced higher stages of understanding and the understanding of positive social interactions were higher than those of negative social interactions at ages 4 and 5.

The primary purpose of this study was to investigate how and to what extent 'representations' affect the students' understanding and the growth of understanding in a technology [GSP]-based collegiate mathematics classroom. There are three themes related as frames of the study along with this purpose, which are mentioned in the first chapter and extended in the second chapter: technology in mathematics education; images on computer screen - visualization and representation; understanding and growth of understanding. Three research questions guided this study: 1) How do students present each component of representations when they study 'transformations' in a technology [GSP]-based classroom? If there is any difference between the first and second presentation for each component, how are they different?; 2) How and to what extent do representations affect the students' understanding and the growth of understanding in a technology [GSP]-based classroom?; What types of benefits and obstacles are there when students study 'transformations' in a technology [GSP]-based classroom?

The understanding demands the different degree of the understanding according to student's learning situation. In this paper, we investigate what is the foundation for the complete understanding for the generalization in the generalization-process and justification of some concepts or some theories, through a case. We discovered that the completeness of the understanding in the generalization-process and justification requires 'the meaningful-mental object' which can give the meaning about the concept or theory to students. Students can do the generalization-process through the construction of 'the meaningful-mental object' and confirm the validity of generalization through 'the meaningful-mental object' which is constructed by them. And we can judge the whether students construct the completeness of the understanding or not, by 'the meaningful-mental object' of the student. Hence 'the meaningful-mental object' are vital condition for the generalization-process and justification.

This paper investigates student conceptual understanding and application on algebra using problem-based curricula. Seven principles which National Research Council announced were considered because these seven principles all involved in the development of a deep conceptual understanding. A problem-based curriculum itself provides a significant contribution to improving student learning. A problem-based curriculum encourages students to obtain a more conceptual understanding in algebra. From the results the national curriculum developers in Korea consider the problem-based curriculum.

Objective: This study examined differences in preschoolers' prosocial decision-making, emotion understanding in prosocial dilemmas based on the age and emotional conditions of a counterpart child, and the effects of emotion understanding on preschoolers' prosocial decision-making. Methods: The participants were 114 children (35 3-year-olds, 39 4-year-olds, and 40 5-year-olds). Each child was presented individually with prosocial dilemma tasks and was asked to make decisions and understand emotions (in prosocial and desire-fulfilled situations) based on the emotional conditions of a counterpart child. Results: First, the 4- and 5-year-olds showed more prosocial decision-making in prosocial dilemmas than the 3-year-olds. Prosocial decision-making was significantly lower when the counterpart child was angry, rather than neutral or sadness. Second, in prosocial situations, the 5-year-olds displayed higher positive emotion understanding scores than the 3-year-olds, And in desire-fulfilled situations, the 3-year-olds showed positive emotion understanding, whereas the 4- and 5-year-olds showed negative emotion understanding. Finally, children were more inclined toward prosocial decision-making when they showed higher emotion understanding in prosocial situations, lower emotion understanding in desire-fulfilled situations, and greater age. These were equal to all emotional conditions of the counterpart child. Conclusion: These results suggest that emotion understanding is an important component of social cognition, which effects preschoolers' prosocial decision-making.

본 연구에서는 화학 개념을 설명하기 위해 과학 교과서에 사용된 비유에 대한 학생들의 이해도를 조사하고, 비유의 제한점으로 인해 유발될 수 있는 오개념을 분석한 후, 개념 이해도에 영향을 미치는 요인에 대해 살펴보았다. 물질의 세 가지 상태, 부피와 압력 사이의 관계, 분자 운동, 상태 변화와 에너지에 대한 비유와 개념 이해 검사, 장독립성 검사, 논리적 사고력 검사를 실시하였다. 분석 결과 절반의 학생들이 교과서의 의도와 다르게 비유를 이해하고 있었으며, 개념 이해도는 그 개념을 설명하는 비유에 대한 이해도 뿐 아니라, 장독립성, 논리적 사고력, 사전 과학 성취도와 유의미한 정적 상관이 있었다. 개념 이해도에 미치는 각 변인의 직 간접적인 효과를 분석한 결과, 사전 과학 성취도의 직접적 영향이 유의미하였으며, 장독립성과 논리적 사고력은 사전 과학 성취도와 비유 이해를 통해 간접적으로 영향을 미칠 수 있는 것으로 나타났다. 이를 바탕으로 과학교육에서 비유 사용의 제한점과 그 함의에 대하여 논의하였다.

We propose a multi-strategic concept-spotting approach for robust spoken language understanding of conversational Korean in a hostile recognition environment such as in-car navigation and telebanking services. Our concept-spotting method adopts a partial semantic understanding strategy within a given specific domain since the method tries to directly extract predefined meaning representation slot values from spoken language inputs. In spite of partial understanding, we can efficiently acquire the necessary information to compose interesting applications because the meaning representation slots are properly designed for specific domain-oriented understanding tasks. We also propose a multi-strategic method based on this concept-spotting approach such as a voting method. We present experiments conducted to verify the feasibility of these methods using a variety of spoken Korean data.

Promoting students' mathematics understanding is an important research theme in mathematics education. According to general theories of learning, mathematics understanding is close to active learning or significant learning. Thus, if a teacher wants to promote his/her students' mathematics understanding, he/she should pay attention to the students so that the students' thinking is in active situation. In the first part of this paper, some mathematics teachers' ideas about paying attention to their students in Chinese high school are given by questionnaire and interview. In the second part of this paper, we give some teaching episodes about how experienced mathematics teachers promote their students' mathematics understanding based on paying attention on them.

This study examined the influences of age, offenders' intention, victims' emotional reactions on the moral emotional understanding of preschool children. Eighty eight children aged 4, 5, and 6 participated in this study, and were interviewed using four moral transgression stories. The responses of the children were then analyzed in terms of the levels of moral emotional understanding, from error through to the understanding of secondary emotions. The results indicated that older children showed higher levels of moral emotional understanding than younger children. Additionally, children's moral emotional understanding was higher in situations in which offenders' behaviors were intentional, and in which the victims expressed sadness. The attribution of moral emotions was influenced by victims' emotional reactions only in 6-year-old children. Discussion of these results also included the development of intervention programs for children with aggressive behaviors, as well as a number of suggestions for future study.

In this paper, we propose a Korean speech understanding model using dictionary and thesaurus. The proposed model search the dictionary for the same word with in input text. If it is not in the dictionary, the proposed model search the high level words in the high level word dictionary based on the thesaurus. We compare the probability of sentence understanding model with threshold probability, and we'll get the speech understanding rate. We evaluated the performance of the sentence speech understanding system by applying twenty questions game. As the experiment results, we got sentence speech understanding accuracy of 79.8％. In this case probability of high level word is 0.9 and threshold probability is 0.38.
