In this research we diagnosed the actual status of the 7th National science elective curriculum and suggested a way to select and organize the content of the new science elective curriculum. The first science education reform was grounded in the structuralism where the structure of discipline was valued above everything else. On the other hand, the second science education reform suggested alternative interpretations of students' opportunity to learn, putting a brake on the structuralist thinking. According to the survey result, the majority of the science elective courses are in need for revision because the contents are overcrowded, too difficult in light of students' learning readiness, failed to draw students' interest in science, and are overlapped and repeated among the 10th grade science, high school science I and II. In particular, Earth Science II and physics II are the most unfavorable courses among students. Thus, we recommended a fundamental change be made in the new curriculum in addition to the optimization of the content. In this paper, we suggested 'topic-centered content organization' for the science elective course I, i.e., Physics I, Chemistry I, Biology I and Earth Science I that is designed for both science track and non-science track students. Since curriculum provides students with an 'opportunity to learn', a curriculum study should focus on what the 'opportunity to learn' is that students ought to be offered. Based on the result of this study, we recommended one way to select and organize the content of high school elective curriculum.

Employing knowledge of adaptive possibilities of agents in multi-agents system, we have explored new aspects of distributed modular systems for building ubiquitous heterogeneous robotic systems using intelligent building blocks (I-BLOCKS) [1] as reconfigurable modules. This paper describes early technological approaches related to technical design, experimental developments and evaluation of adaptive processing and information interaction among I-BLOCKS allowing users to easily develop modular robotic systems. The processing technology presented in this paper is embedded inside each $DUPLO^1$ brick by microprocessor as well as selected sensors and actuators in addition. Behaviors of an I-BLOCKS modular structure are defined by the internal processing functionality of each I-Block in such structure and communication capacities between I-BLOCKS. Users of the I-BLOCKS system can easily do 'programming by building' and thereby create specific functionalities of a modular robotic structure of intelligent artefacts without the need to learn and use traditional programming language. From investigating different effects of modern artificial intelligence, I-BLOCKS we have developed might possibly contain potential possibilities for developing modular robotic system with different types of morphology, functionality and behavior. To assess these potential I-BLOCKS possibilities, the paper presents a limited range of different experimental scenarios in which I-BLOCKS have been used to set-up reconfigurable modular robots. The paper also reports briefly about earlier experiments of I-BLOCKS created on users' natural inspiration by a just defined concept of modular artefacts.

In the present study, we apply the multiple cue probability learning (MCPL) paradigm to examine consumer learning from feedback in repeated trials. This paradigm is useful in investigating consumer learning, especially learning the relationships between the overall quality and attributes. With this paradigm, we can analyze what people learn from repeated trials by using the lens model, i.e., whether it is knowledge or consistency. In addition to introducing this paradigm, we aim to demonstrate that knowledge people gain from repeated trials with feedback is robust enough to weaken one of the most often examined contextual effects, the asymmetric dominance effect. The experiment consists of learning session and a choice task and stimuli are sport rafting boats with motor engines. During the learning session, the participants are shown an option with three attributes and are asked to evaluate its overall quality and type in a number between 0 and 100. Then an expert's evaluation, a number between 0 and 100, is provided as feedback. This trial is repeated fifteen times with different sets of attributes, which comprises one learning session. Depending on the conditions, the participants do one (low) or three (high) learning sessions or do not go through any learning session (no learning). After learning session, the participants then are provided with either a core or an extended choice set to make a choice to examine if learning from feedback would weaken the asymmetric dominance effect. The experiment uses a between-subjects experimental design (2 × 3; core set vs. extended set; no vs. low vs. high learning). The results show that the participants evaluate the overall qualities more accurately with learning. They learn the true trade-off rule between attributes (increase in knowledge) and become more consistent in their evaluations. Regarding the choice task, there is a significant decrease in the percentage of choosing the target option in the extended sets with learning, which clearly demonstrates that learning decreases the magnitude of the asymmetric dominance effect. However, these results are significant only when no learning condition is compared either to low or high learning condition. There is no significant result between low and high learning conditions, which may be due to fatigue or reflect the characteristics of learning curve. The present study introduces the MCPL paradigm in examining consumer learning and demonstrates that learning from feedback increases both knowledge and consistency and weakens the asymmetric dominance effect. The latter result may suggest that the previous demonstrations of the asymmetric dominance effect are somewhat exaggerated. In a single choice setting, people do not have enough information or experience about the stimuli, which may lead them to depend mostly on the contextual structure among options. In the future, more realistic stimuli and real experts' judgments can be used to increase the external validity of study results. In addition, consumers often learn through repeated choices in real consumer settings. Therefore, what consumers learn from feedback in repeated choices would be an interesting topic to investigate.

The purpose of this study is to clarify the specific terms of epistemic and epistemological by reviewing the literature on epistemological understanding of science learning, examine the necessity of epistemic discourse analysis based on the view of social epistemology, and provide an exemplar of practical epistemology analysis for elementary children's science learning. The review was conducted in terms of meaning and terminology about epistemic or epistemological approach to science learning, epistemology of/for science, and methodologies for epistemic discourse analysis. As an alternative way of epistemic discourse analysis in science classroom I employed practical epistemology analysis (by Wickman), evidence-explanation continuum (by Duschl), and DREEC diagram (by Maeng et al.). The methods were administered to an elementary science class for the third grade where children observed sedimentary rocks. Through the outcomes of analysis I sought to understand the processes how children collected data by observation, identified evidence, and constructed explanations about rocks. During the process of practical epistemology analysis the cases of four categories, such as encounter, stand-fast, gap, and relation, were identified. The sequence of encounter, stand fast, gap, and relation showed how children observed sedimentary rocks and how they came to learn the difference among the rocks. The epistemic features of children's observation discourse, although different from scientists' discourses during their own practices, showed data-only conversation, evidence-driven conversation, or explanation inducing conversation. Thus I argue even elementary children are able to construct their own knowledge and their epistemic practices are productive.

The rectnt studies on the learning of the scientific concepts have suggested that most students have misconceptions related to the contents to be learned and that those misconceptions exert their influences on the subsequent learning of the content Those facts necessitate the identification of the misconceptions before the instructions and the preparation of the instructional materials based on those misconceptions identified. Several studies also revealed that such biological areas as cell division, reproduction and fertilization were ranked among the most difficult areas for high school students to learn. Therefore, this study had its triple objectives as follows: (1) Identification of misconceptions in such areas as cell division, reproduction and fertilization. (2) Investigation of the current high school biology textbook I's as the sources of those misconceptions. (3) Development of teaching materials based on the misconceptions identified and the problems in the textbooks analyzed. This study identified several misconceptions held by high school students of biological concepts related to the conceptual areas of life-continuity, and found the problems in learning of the high school biology textbooks. Based on the misconceptions and the problems, a teaching/learning model and its content material were developed at the final course of this study.

The purpose of this study is to investigate what English teachers think about what and how to teach culture, as a way of helping students build relevant background knowledge and enhance their motivation in learning English. A total of 300 teachers completed a self-report questionnaire in four areas: (i) their understanding and liking of English-spoken countries, (ii) their use of materials and tools for teaching culture, (iii) their consciousness of teaching culture, and (iv) their needs for culture learning in the teacher-training program. The results show that (i) they think American culture is dominant in EFL but they are much interested in British culture; (ii) they rely on internet most for their cultural experience while they think students get much of the cultural information from textbooks; (iii) they are very much conscious of the importance of teaching culture for improving students' English proficiency; (iv) they want to learn in the teacher training program more about cultural practice, which can be subsumed under the so called 'small c'. The findings suggest that (i) textbooks need to include contents to promote students' cultural awareness and foster intercultural competence, (ii) teachers should use authentic materials with appropriate adaptation, and (iii) a teacher training program should cover a wide range of contents and skills for teaching culture.

In this study, I developed an activity oriented lesson to support the understanding of probabilistic and quantitative estimating population ratios according to the standard statistical principles and discussed its implications in didactical respects. The developed activity lesson, as an efficient physical simulation activity by sampling with replacement, simulates unknown populations and real problem situations through completely closed 'Closed Box' in which we can not see nor take out the inside balls, and provides teaching and learning devices which highlight the representativeness of sample ratios and the sampling variability. I applied this activity lesson to the gifted students who did not learn estimating population ratios and collected the research data such as the activity sheets and recording and transcribing data of students' presenting, and analyzed them by Qualitative Content Analysis. As a result of an application, this activity lesson was effective in recognizing and reflecting on the representativeness of sample ratios and recognizing the random sampling variability. On the other hand, in order to show the sampling variability clearer, I discussed appropriately increasing the total number of the inside balls put in 'Closed Box' and the active involvement of the teachers to make students pay attention to controlling possible selection bias in sampling processes.

Recently SW education has been emphasized in Korea, but many students do not have many opportunities to learn computer science. In this paper, I organized a computer science show to enhance interest and understanding of computer science. The computer science show consisted of understanding binary systems, send a text message, parity bit magic, finding a number card, and collecting colors (orange games). I applied the computer science show to elementary school students and looked at the results. Most of the students who participated in computer science shows did not have an "participation experience of computer science shows". As result of surveys, many students answered "I am interesting about computer science shows," "I am interested in computer science," and "I would recommend it to my friends nearby." Through research, I learned that computer science shows are a way for elementary students to draw interest in computer science and to create curiosity and interest in computer science. I found from research that computer science shows are a way to reduce students' learning burdens and to increase interest in computer science.

Chinese is a topic-prominent language, so when we learn Chinese we should know the discourse function of the Chinese language. Most of the Korean student think Chinese sentences should appear in the order of S-V-O and they always make mistakes when they use Chinese. I think Korean is very similar with Chinese in the discourse function. Hence, in this paper, I try to find a method of teaching Chinese topic sentence. It does so by comparing Chinese with Korean in the light of discourse function. I think when Korean student know how to use Korean topic sentence to explain the discourse functions of the Chinese language, they will not make similar mistakes. With this understanding in mind, chapter 2 tries to show various topic sentences to prove that 'topic' is very important in Chinese sentences. This is why we say Chinese is a topic-prominent language. In chapter 3, I analysis the sentences that students made, and highlight the reasons why they made mistake. The result lies in the reason whereby they always think Chinese should appear in the order of S-V-O. They do not understand why some sentences appear in the order of O-(S)V or S-O-V. It show that they do not know what is topic sentence and do not know how to make topic sentences. Sometime I have them translate them into Korean, but they also make Korean sentences like in the order of Chinese S-V-O. Therefore, I think, under this circumstance, to let them to translate and to speak in Korean in topic sentence, get some feelings about Chinese topic sentences, and tell and make Chinese topic sentences are naturally critical in their training.

Previous scholars have studied Daesoon Jinrihoe mainly through its scriptures and doctrines; however, in this essay I have combined data from a questionnaire with interviews I conducted to observe women's religious engagement from their own perspectives. I conducted my fieldwork from October 23 to 26 at Yeoju Headquarters in Korea and received 81 questionnaire replies. This ongoing project will shed light on the niche for women in Korean new religious movements. This essay is divided into three parts. First, I reviewed 5 articles on general attitudes towards women within Daesoon Jinrihoe to serve as a doctrinal introduction. Second, I used the Ladies Club, the Women's Assembly of the Department of Social Welfare, and female students from the Inter- national Volunteers Association to better understand women's participation and education in Daesoon Jinrihoe on an institutional level. Third, I issued a questionnaire in order to learn respondents' sex, age, educational background, and birth place and used those data points determine patterns in how the above influence religious participation and positions in Daesoon Jinrihoe. My investigation showed that both the self-expectation and division of labor among the followers at Yeoju Headquarter were affected by and corresponded to social gender roles. Moreover, the emphasis on missionary work rather than centralized hierarchy contributed to a reduction in the influence of gender-segregation and led to relative coherence in terms of gender relations within Daesoon Jinrihoe.
