  • Gestures accompanied by scientific discourses play an important role in constructing mental models and making model-based inferences. According to embodied cognition literature, gestures can be a source of recognition of the mental models of students and help them in changing naive beliefs about science. This study intends to compare the gestures of scientists with that of middle school students in explaining scientific phenomena and to explore the relationship between gestures and scientific discourse. In the study, 10 scientists and 10 middle school students participated in clinical interviews and the tests of knowledge and self-efficacy. Participants engaged in one-on-one clinical interviews with semi-structured questions about three tasks regarding the molecular movement and the state change of matter. Four researchers carried out open coding and applied a constant comparison method in order to analyze video-recorded gestures. This study found four themes (feature of gesture, use of gesture, content of gesture, function of gesture) about the differences of gestures between scientists and middle school students. Scientists used more diverse and elaborate gestures systematically and frequently in the interview. Although students used gestures in their scientific talk and reasoning, the gestures of students were not well grounded on scientific knowledge and had different functions from those of scientists. The findings revealed that gestures can represent underlying cognition and strengthen scientific thinking. We should encourage students to use gestures as a tool to understand scientific concepts and make inferences.

  • The purpose of this study is to investigate the features of science classes of Science Core Schools (SCSs) perceived by students. 654 students from 14 SCSs were surveyed with two open-ended questions on the features of science classes. The students' responses were analyzed with NetMiner 4.5, in terms of the centrality (of betweenness and of degree) analysis and the community analysis. The results of the research are as follows: (1) the science classes of SCSs were perceived by students to be of the environment of free questioning, active participation and communication, caring teacher, more science experiments and advanced contents, and knowledge sharing; (2) science classes in SCSs were perceived to be different from those of ordinary high schools because SCSs provide more opportunities for science-related special courses (like project work, advanced science subjects), extra-curricular activities, inquiry and research activities, school supports, hard-working classroom environment, longer studying hours, R&E and club activities. The students' perceptions of SCS science classes appear to be in line with the characteristics of 'good' science lessons from previous studies. The SCS project itself and the features of SCS science classes would help us to see how we introduce educational innovations into actual schools.

  • This study was made to find out how stress affect on nutrition status of the college freshmen who were experiencing physical growth and development as well as drastic emotional change. 400 male and female freshmen in 4 year colleges were surveyed respectively through the health check-up procedure for college entrance in February, In order to find out the stress in each group frustration, deprivation, lack of self efficacy, type A behavior and anxiety response were surveyed through 10 questions with total 40 points by assigning 4 points for each question. Diet Status was expressed by DDS (Dietary Diversity Score by 5 food groups) and DVS(Dietary Variety Score). 24-hrs recall method was used to find out the quantity of daily nutrient of EAR(estimated adquacy ratio) by KDRIs(Korean Dietary Recommended Intakes). Nutrition level was analyzed by Can-Pro for professionals (Korea Nutrition Association). And for the quality intake, percentage was calculated and MAR(Mean Adequacy Ratio) were produced. Highest point was obtained in the stress of anxiety with the total 40 score of 30.20, and the scores were 29.79, 28.67, and 28.39 for deprivation, type A behavior and frustration respectively. There was no difference of blood components in accordance with stress type. Stress type was divided into less sensitive group and highly sensitive one and the relationship with the blood nutrient status was observed. The difference of blood component and blood pressure in sensitive and highly sensitive groups was observed in deprivation and anxiety. The index of blood pressure(p<0.05), hemoglobin(p<0.01), HDL-cholesterol(p<0.05), and Fe(p<0.05) was high in the deprivation of sensitive group. Blood pressure and hemoglobin was high in type A of sensitive group(p<0.05). And the contents of blood triglyceride was high in the anxiety of sensitive group(p<0.001) The result of nutrition intake analysis according to stress type showed that there was low intake for energy, riboflavin, and niacin. When the degree of deprivation was high there was a lack of riboflavin intake and there was no significant difference of nutrition intake in lack of self efficacy, type A behavior and anxiety response. Thus, it is necessary for colleges to educate the students to maintain mental stability through various programs and activities after catching a kind and extent of the stress college students we meeting with like the confusion of value system, open heterosexual relationship, and the employment difficulties linked with political uncertainty and economic recession.

  • The purpose of the research was to develop an analysis framework for Korean mathematics textbooks from a critical mathematics education perspective. For this, we conducted a comprehensive literature review regarding critical theory, critical education, and critical mathematics education. Based on the literature review, we derived a preliminary framework for textbook analysis. To validate the preliminary framework delphi survey was carried out twice with 21 expert panelists in the field of mathematics education and multicultural education. The first delphi survey was conducted with open-ended questions to investigate diverse opinions regarding educational goals, contents, and teaching methods of critical mathematics education. The second delphi survey was conducted with Likert-type scale and it was analyzed using Mean, Contents Validity Ratio, Degree of Consensus. As the result of the whole research procedures, the final analysis framework was developed consisting of four categories: classical knowledge, community knowledge, communicative knowledge, and political knowledge. A development of the analysis framework from a critical mathematics education perspective could give a significant impact on the mathematics curriculum or mathematic teacher education in the Korea and a meaningful initial step for the effort of practicing critical mathematics education. It is expected that this study could not only incite consideration for the better mathematics education but also expand the prospect of research and practice in mathematics education. This study would provide a new paradigm of future mathematics education with which to teach and guide students to become members of world civil society with mathematical power and critical competency.

  • This study was intended to provide women who are supposed to experience childbirth with effective nursing care exploring the childbirth experience. The purpose of this paper is to give an answer to the question of what the childbirth experience is, and phenomenological method has been used for that purpose. 17 primiparous mothers right after delivery in one university hospital of J city were served as subjects for this research. Data were collected June to October, 1993 through in depth interview with subjects using unstructured and open questions about the childbirth experience. Van Kaam's phenomenological analysis method was used for the analysis of the data. The results of the study are summarized as follows : The contents of the experience which primiparous mothers had undergone through childbirth were pain, fear, worry, relief, lightness, thankfulness, unsatisfactory, unreality, holiness for a new life, identifying the meaning of life, becoming a mother. 1. Experience before delivery Mothers experienced pain, fear, worry, unsatisfactory, relief, and thankfulness before delivery. Subjects' descriptions about the pain appeared to be various ; unbearable pain, bearable pain, anticipated pain. And their reactions were also various ours ; some endured pain, sought alternative method i.e., surgery, didn't want to reexperience it, or accepted it as women's fate. Subjects experienced fear for anticipated pain, suffering pain, and possible delayed delivery progress and were worried about delivery progress and baby wellbeing. Also, Subjects were unsatisfied with professionals' unfaithful attitude, their spouses' absence, and the ignorance of their pain. But subjects became relieved at the accustomed surroundings, good progress of delivery, support of family, care of professionals and support of other family. And they expressed their thanks to the professionals and family members for doing their best and also to their mothers who gave birth to them. 2. Experience after delivery Subjects experienced lightness, thankfulness, unsatisfactory, worry, unreality, holiness for a new life, identifying the meaning of life, becoming a mother after delivery. Mothers experienced lightness from the fact that it is over, and freshness right after delivery. They were thankful that they delivered vaginally and had an easy delivery. Subjects who delivered female baby were unsatisfied and some were worried about rearing the baby. By confessing, "I have no specific feeling, I am very confused, It is unrealistic, I feel strange", they expressed the unrealistic aspect of childbirth experience. Subjects felt holiness for a new life for novelty and birth of life. They identified the meaning of life from the fact that they felt worthy, fulfilled their duty, had their own baby, accomplished an important affair. After they experienced what it is to be a mother, they realized with it is being a mother and had a rearing expectation for the baby. The results of the study will provide basic data for caring the childbearing women.

  • In today's secondary school mathematics curriculum, assessment is to be focused on evaluating the student's mathematical thinking rather than finding the correct solution to the problem. A descriptive evaluation method is therefore introduced to the school districts and suggested as an alternative assessment method in K-12 school mathematics. Descriptive evaluation method is widely available for use in schools, but there are barriers to using it since the teachers are forced to use the method by the school districts. In this research, we surveyed 120 secondary school mathematics teachers in Seoul and the surrounding metropolitan area to understand the status and the perception about using descriptive evaluation. The goal of the study was to find and understand the direct implications of using the new assessment method in secondary mathematics classes. The study showed that most of the mathematics teachers used the descriptive assessment method during their regular exam periods which is given twice per semester. Most of the open-ended problems used for descriptive evaluation were medium or high level math questions which were graded by the teachers at least 3 times to ensure objective evaluation. The teachers stated that objectivity in grading, administrative situation, and development of descriptive problems were the difficult barriers in descriptive evaluation. The teachers in the survey also commented that teachers' administrative responsibility should be reduced and that school environment in general should be improved for the new assessment method to become successful. Finally, the study showed that development of more descriptive problems with specific grading guidelines need to be developed for each grade level.

  • The purpose of this study is to develop academic resilience scale for gifted youth. We extracted the pilot questionnaire of 101 items from open-ended questions with 178 scientifically gifted students and literature review. Item analysis and exploratory factor analysis were also carried out with data of 240 gifted youth. Finally, 11 factors from which 42 items were extracted and validated through the confirmatory factor analysis involving 444 gifted youth throughout the nation. The names of the extracted factors were sense of purpose, self-understanding, educational aspirations, academic self-regulation, task commitment, attribution for success (ability), attribution for success (effort), the interpersonal relationship (friend), the interpersonal relationship (parent), the interpersonal relationship(teacher), and optimism. The results show that all of the path coefficient and construct reliability, AVE (Average Variance Extracted), and coefficient of determination were all acceptable. The result of the study indicated that Academic Resilience Scale for Gifted Youth was positively and significantly correlated with School Adaptation Scale and Resilience Scale. However it was negatively correlated with Academic Burnout Scale, and it was statistically significant. Thus, Academic Resilience Scale for Gifted Youth demonstrated satisfactory internal validity and external validity. The results of the present study suggests theoretical and practical implications of the newly developed Academic Resilience Scale for Gifted Youth.

  • A demand for user's participation in the designing process, which is called the participation design, is increasing with social change. Practically, however, there is lack of researches on the improvement of the problem in actual design development and participation design effect. In order to understand the field-based participation design effect in view of user's change of awareness on participation design, this study carried out a survey on the change of awareness through a design workshop in which all stakeholders have participated on the subject of agricultural direct sales facilities as a part of participation design programs. Many references were reviewed first to understand the participation design principles and their current research trend. Next, the questionnaire was developed using an effectiveness verification model for an effective analysis. A design workshop as one of the participation design programs was organized and applied for the field response. In order to analyze the effect, the survey on participants' change of awareness was carried out before and after the program. The survey questionnaires were about motivation, knowledge, recognition, function, and participation and asked the design study graduates. The participation design effect was supplemented by additional open questions. As a consequence, the participants in the participation design program showed the noticeable effect in knowledge and function about the agricultural direct sales facilities. It was found that they were also highly satisfied with the participation design result and they recognized an importance of collaboration. This study also showed that a sufficient time schedule considering agricultural village life should be given for a smooth operation of the program and also a working environment is necessary for designing work.
