This study aims to explore the effects of deductive FFI and inductive FFI in L2 learners' grammatical achievement and their reaction to the grammar instruction. 84 students were placed into three groups: 29 given deductive FFI(DG), 28 receiving inductive FFI(IG), and 27 with traditional instruction(CG). All students completed pre/post tests and questionnaires, and took a delayed post test 9 weeks after the treatment. For statistical anlayses of all the quantitative data, a one-way ANOVA, paired samples T-test, and repeated measures ANOVA were performed. The results indicated that both deductive and inductive FFI affected learners' grammatical achievement and their achievement was sustained over time. Deductive FFI was more effective than inductive FFI, whereas the IG students more positively changed their attitudes and perceptions to the grammar instruction. These findings of the study imply that FFI should be valued in an Korean EFL classroom, which would contribute to further longitudinal research for its sustainability.

Objective：This was conduced to evaluate the effect of early intervention to promote the development of children with developmental disorders. Methods：49 children(31 in PDD group and 18 in DLD group) participated in a one year day treatment program conduced from 1996 to 1999. They were performed PEP, CARS, and SMS. They were grouped by diagnosis, comorbidity, chronological age and CARS score at the beginning of the program and the treatment effect was compared. Results：The children who participated in the day treatment program showed significant increase in their PEP, SMS score, and decrease trend in their CARS score. When children were grouped by diagnosis, comorbidity, chronological age, and severity in CARS score we did not find out significant difference between groups. Conclusion：Our data suggest that the day treatment program which emphasis on development is effective in treating children with developmental disorders.

일방향 응고법으로 주조된 아공정 회주철의 파단면을 주사전자현미경을 이용하여 분석하였다. 회주철에서는 흑연의 형태변화로 인하여 파단면의 형상에 큰 차이점이 유발되었으며, 이와 같이 다양한 파단면의 특성분석을 위하여는 주사전자현미경의 이차전자(secondary electron)를 이용한 입체사진(stereopair micrograph)을 촬영하여 입체전인 관찰을 수행하는 것이 효과적이었다. 일방향으로 응고된 D형 흑연을 갖는 회주철이 A형 회주철에 비하여 열등한 기계적 성질을 갖는 것은 극히 미세한 망장(網狀)의 혹연조직과 오스테나이트의 이차 수지상 조직(secondary dendrite arms)의 형성에 기인하는 것으로 확인되었다. 이들 조직은 고 강도의 철상을 거치지 않고 주로 흑연상 주위의 취약한 부분을 통하여만 파괴가 전파되도록 유도함으로써 D형 주철의 파괴강도를 저하시킴이 발견되었다. A형 회주철에서는 조직의 조대함으로 인하여 고 강도의 철조직이 파괴에 참여하게 되어 파괴강도를 높여주는 것으로 확인되었다.

미국에서 학교 수학 수업에서의 개방적 접근은 일본과 미국 연구자들의 공동연구의 결과물이다. 우리는 그것에 대한 세 가지의 측면을 실례로 살펴보면 접근을 시도하겠다. : 1) 개방된 과정(open process)(문제의 해답에 이르는 방법이 여러 가지이다: 2) 개방형 문제(open-ended problems)(문제에 대한 정답이 여러 가지가 될 수 있는 문제), 3) 일본에서 '문제로부터 문제(from problem to problem)'라고 불리는 것 혹은 문제고안(problem formulating)하기(학생들이 새로운 문제를 명확하게 나타내기 위해 자신의 생각을 써 내려 가는 것)수학 지도에서 일본의 개방적 접근에 대한 우리의 이해를 바탕으로, 우리는 미국에서 보다 효과적인 수학 지도를 위한 몇 가지 방법을 선택 적용해 보았다. 이러한 접근의 대부분은 학습 계획안을 만들 때 여러 교사가 함께 참여하고 일련의 토론과 수정과정을 거친 뒤, 많은 부분이 개선되고 효과적인 계획안을 만들어 낸다는 점에서 미국의 수학교사들에게 새로운 것이다. 또한 이 접근법에서는 교사가 문제를 해결하는 과정에서 학생 개개인이나 그룹을 활동적으로 관찰하여 그들의 활동을 비교하고 토론한다.

The purpose of this study is to find out how those taking early childhood preservice teachers experience their learning through learner-centered education and the meaning given by such experiences to grasp their values. Especially, to look into experiences of learning the project approach theory studied and directly experienced, which is one of the early childhood educational approach methods, data on participatory observation, personal interviews, personal reflective journals, activity reports and ect. were collected and analyzed by the current writer, who fully participated in the class. The meaning of early childhood preservice teacher'experiences in the project approach was analyzed from the two aspects of 'my' learning activities and 'teacher's teaching activities. In the aspect of 'my' learning activities, they got indulged through purposeful practices in the process of tackling problems that originated from personal interest and wanted to share the joy of learning they'd had with others. Aware of themselves as doers of behavior and thinking, they were found to be able to focus an 'my' own learning activities based on these learning experiences of theirs. In the aspect of 'teacher's teaching activities, project theories and practices done at the same time helped them internalize the project and they learned possible changes ign the project by experiencing actual cases. To sum up, the project approach has its meaning in that it not only helps teachers learn theoretical knowledge but also have reflective thinking through their experiences as doers of learning and form practical knowledge. Accordingly, it indicates th need for intensive discussion on the project approach as a way to educate pre-teachers or current ones.

This study examined Korean immigrant elderly's generativity and care-giving experiences of their grandchildren according to their level of generativity. In-depth interview and participant observation method were used. First, this study used Loyola Generativity Scale in order to find Korean immigrant elderly's generativity level. 4 grandparents were selected as a group of low generativity level and 4 grandparents as high level. Grandparents with low generativity level showed non-voluntary care-giving, severe care-giving stress, guilty feeling for their adult children and shame for their ancestors, anxiety for the unstable future, lack of self-care, and lack of social assistance. Grandparents with high generativity level showed voluntary care-giving, positive reaction for the reversed parental care, feeling of usefulness for care-giving, hope for the future, existence of self-care, and existence of social assistance. Further discussion and suggestions were made from the study results.

Massively Multiplayer Online Role-Playing Games (MMORPGs) are played by millions of people around the world. Within MMORPGs, players explore, solve mysteries, craft items, battle against dungeon or raid bosses, or compete against other players, all while using a variety of information and information behaviors. Role-players in MMORPGs develop identities and engage in interactive storytelling with other role-players as their characters. An ethnographic approach combining overt participant observation and engagement, semi-structured interviews, and artifact collection was used to explore and describe the social information behaviors of role-players through the lens of the theory of information worlds. The social types evident in the role-playing community in WildStar, a science fantasy-themed MMORPG, are closely interrelated to and differentiated by social norms and information values that dictate acceptable characters, stories, character actions, and appropriate lore sources as well as how to role-play without violating the boundary between in- and out-of-character information worlds. Role-players maintained the in-character and out-of-character boundary using a set of specific information behaviors to enable engaging and immersive role-playing experiences. Implications of the findings for the theory of information worlds as well as potential applications of role-playing and MMORPGs are also discussed.

This study aimed to investigate teacher learning in the context of a community. For the purpose of this study, two research questions about the kinds of teacher noticing in a community and the role of partnership were addressed. To build a learning community, a professional development project, PRIME, established partnerships with 11 high schools and one of the cluster meetings were investigated in this study. Three mentor teachers, three preservice teachers, and one university supervisor participated in the cluster meeting. For this study, the multiple data such as audio tapes of cluster meetings, observation notes, and interviews were analyzed using the analysis of narratives. The results showed that the participants engaged in different kinds of noticing of their own beliefs about teaching and learning, teacher practices, and teacher identities including noticing of students' understanding in classroom situations. The partnership played the crucial role of reinforcing relationships among teachers, assigning tasks, and creating various communities.

The purpose of this research is to investigate how an elementary English class is presented in terms of communicative properties using COLT and TALOS because previous studies mainly used COLT. A lack of TALOS has shown on the previous studies. Also, this study takes a close look into whether the English class is communicative or not communicative since previous studies criticized in that elementary English classes are not communicative. For the purposes of this research, COLT part B and TALOS low-inference were used to analyze one elementary English class which had won the grand prize at English class contest. The result of this study revealed that the class is communicative in terms of high quantity and quality of students utterances, high ratio of students' discourse initiation, students' unpredictable information giving utterances and extension of utterances. Findings from this study revealed the good elementary English class characteristics of this class: students' participation, focus on affective atmosphere, students-directed activities, and unconscious internalization of target expressions through repetition.

This study examined poor custodial grandparents' life story and care-giving experiences of their grandchildren. 8 grandparents were selected and in-depth interview and participant observation method were used. They showed a miserable life from the birth and discriminative experience of the deprivation of educational opportunities as childhood nadir experiences. They showed the regret for their inability as youth/midlife low point and financial difficulty as old life nadir experiences. In terms of care-giving experiences of their grandchildren, they showed non-voluntary care-giving, anxiety for the generational continuation of hardship, and lack of familial assistance. Poor custodial grandparents also used family-centered value, community-based social assistance, and self-assurance through their sacrifice as their adjustment strategy. Several research themes such as the importance of basic trust in childhood, the experience of financial difficulties, the importance of community-based social assistance, and self-assurance through their sacrifice were suggested for further research.
