Communication education research has focused on the effects of instructor characteristics on learning. It is necessary to consider student characteristics as well to develop an effective teaching strategy. The current study tries to classify students into multiple distinct groups depending on their personality traits and communication characteristics and investigates differences in effects of teacher characteristics between those groups. A survey on unversity students was conducted to collect data. A cluster analysis was carried out to identify distint sub-groups of respondents by their personality traits and communication characteristics. The analysis yielded two distinct groups. The two groups were named stable-reticent group', and 'neurotic-talkative group' respectivley. Series of multiple regression were carried out in order to investigate differences in the effects of instructor characteristics. The analyses found different patterns of effects between the two sub-groups. The findings suggest that it is necessary to adopt different communication styles and teaching strategies depending on student types.

Despite evidence that early childhood teachers play a critical role in guiding children through their child assessment, most beginning teachers in the survival stage face the greatest difficulties in this area. Using the intentional and purposeful tools of action research, this collaborative action study supports a beginning teacher in reflecting upon her perceptions of the 'child assessment' of young children and devising and evaluating good guidance practices. During the course of the study, the participating teacher became engaged in more reflective teaching which prompted her to perceive the "child assessment" of the children from different perspectives. As her understanding of the importance of making her curriculum and classroom climate more engaging and meaningful deepened and she reconceptualized her notion of child assessment, the teacher witnessed positive changes in her students' behaviors which, in turn, increased her sense of efficacy. These very positive, empowering results are strong recommendation for using collaborative action research especially in the novice years of teaching for it provides the teacher with a life-long transformative tool for professional development.

The handicapped frequently suffer from inappropriate food intake often resulting in overweightness, malnutrition, and poor growth and development. Our study was done on 7 to 12 year old mentally retarded children attending a special education school in Seoul. We administered questionnaire surveys and 3-day dietary recalls of the subjects, with help when needed from their stay-at home or their care-giving teachers. The questionnaires covered the general characteristics and dietary behaviors of the subjects. The degrees of handicap of the 142 children ranged from the trainable (54.9%), the educable (31.0%), and the non-trainable (14.1%). Of the children studied, 70.4% had ‘breakfast always’, which was higher than normal. Appetites were highest in the Down's Syndrome group. We found that the more serious the handicap, the higher the breakfast eating ratio and appetite level. The main reason for their missing breakfast differed according to the handicap level: ‘late rising’in the educable and non-trainable groups but ‘no appetite’in the trainable group. Most of the children (52.2%) spent less than 20 minutes eating their meals, the parents described their children's dietary habit problems as a pica (22:3%) or overeating (17.3%) , and they indicated that teaching the children how to use spoons and chopsticks (33.1%) was the most stressful. Actually more than 85% of the subjects could not use chopsticks, and skill of using cutlery was significantly different according to the degree of handicap. The food preference for milk products was the highest. It was interesting that the handicapped who had serious food pica didn't like food groups such as grains/starches, meats/fishes/eggs/beans or vegetables/fruits.

Chronic neuropathic pain is one of the primary causes of disability subsequent to spinal cord injury. Patients experiencing neuropathic pain after spinal cord injury suffer from poor quality of life, so complementary therapy is seriously needed. Dehydrocorybulbine is an alkaloid extracted from Corydalis yanhusuo. It effectively alleviates neuropathic pain. In the present study, we explored the effect of dehydrocorybulbine on neuropathic pain after spinal cord injury and delineated its possible mechanism. Experiments were performed in rats to evaluate the contribution of dehydrocorybulbine to P2X4 signaling in the modulation of pain-related behaviors and the levels of pronociceptive interleukins and proteins after spinal cord injury. In a rat contusion injury model, we confirmed that chronic neuropathic pain is present on day 7 after spinal cord injury and P2X4R expression is exacerbated after spinal cord injury. We also found that administration of dehydrocorybulbine by tail vein injection relieved pain behaviors in rat contusion injury models without affecting motor functions. The elevation in the levels of pronociceptive interleukins ($IL-1{\beta}$, IL-18, MMP-9) after spinal cord injury was mitigated by dehydrocorybulbine. Dehydrocorybulbine significantly mitigated the upregulation of P2X4 receptor and reduced ATP-evoked intracellular $Ca^{2+}$ concentration. Both P2XR and dopamine receptor2 agonists antagonized dehydrocorybulbine's antinociceptive effects. In conclusion, we propose that dehydrocorybulbine produces antinociceptive effects in spinal cord injury models by inhibiting P2X4R.

The aim of this study was to confirm the effectiveness of learner-centered teaching models to reduce the dental anxiety. 18 children with age of 10 at the case group and 22 children with age of 10 at the control group was completed. Children from case group were participated in learner-centered oral health education, while those from control group were participated in instructor-led oral health education. Dental Anxiety Scale (DAS) at each groups were measured before oral health education, after then, oral health education of two types at each groups were separately conducted during 1-hour, 2 times. Learner-centered oral health education adapted the systematic desensitization (Tell-Show-Do) was conducted for case groups. Instructor-led oral health education was performed by using the presentation file (PPT). The change of Dental Anxiety Scale (DAS) were compare between case and control groups to evaluate the effect of learner-centered teaching type. After oral health education, DAS of the case and control groups at the baseline were 9.61 and 11.14, respectively, and the average DAS decline of case and control groups after oral health education were 2.48 and 0.55, respectively. These findings show that a learner-centered teaching type is an effective oral health program to reduce of dental anxiety in childhood.

This study investigated secondary school science teachers' experiences to explore the influencing factors in science teachers efficiency (STE). The participants, thirty three secondary school science teachers who have more than four years of teaching experience, were interviewed about describing each teacher's experience throughout one's years of teaching. The grounded theory introduced by Strauss and Corbin (1998) was used to analyze the data in this study. The results of paradigm analysis revealed that STE is influenced by 125 concepts, 38 sub-categories, and 16 categories. In a paradigm model, the central phenomenon was 'constructing STE', and the causal condition was 'want to be a teacher' as career choice motivation. The contextual conditions that have an affect on the central phenomenon were 'self awareness of the teacher' and 'social awareness of the teacher.' The mediate conditions, which facilitated or restrained the action/interaction strategies, were 'societal tendency', 'school climate', and 'personal context.' The action/interaction strategies to control the phenomenon were 'following the line,' 'identifying effective teaching strategies,' 'taking teacher education programs,' and 'contributing to school improvement.' The consequences were 'teacher's self awareness', 'challenge,' and 'stagnating in teaching.' The overall conclusion drawn from this research is that, the definition of STE is beliefs in science teachers' capabilities to set up objects in some school teaching context and, organize and execute the course of action required to attain these. Additionally, STE has three dimensions of teacher's behaviors: science instructional efficiency, efficiency in engaging students, and efficiency in managing school conditions. This study offers insight into the nature of STE and theoretical framework. These findings may give science teachers and teacher educators the practical knowledge necessary to build effective training programs and interventions that would help increase STE and facilitate effective teaching.

This study examined the effects of collocation-based instruction on L2 vocabulary acquisition and learners' interests in it. Fifty one students were randomly assigned to the experimental group (collocation-based instruction group) and to the control group. The participants' English vocabulary capacity was checked through pre and post tests, and two surveys were used to probe the learners' vocabulary learning behaviors and their interests in English vocabulary learning respectively. To better understand the participants' opinions and feelings on the collocation-based learning, follow-up interviews were also carried out. The results showed that second language (L2) learners' vocabulary capacity was significantly improved through collocation-based instruction. However, the participants' degree of interest in vocabulary learning did not reach our expectation partly because of external factors such as the Test for the College Scholastic Ability Test (CSAT) and lack of familiarity of collocations. Such results indicate that the high school students' rooted perception of putting importance on test-based language learning could not be easily changed since it is closely related to their immediate needs. Based on the results, this study suggested how to implement collocations into L2 classrooms effectively.

This research primarily aimed to investigate proficient and less proficient EFL readers' awareness and experiences about learning to read and reading in English. The secondary purpose was to explore the participants' reading strategies, and to discover how the genres of English texts influence their reading processing behaviors. The participants consisted of four college students in engineering aged 21-25 years. Three data sources were employed: questionnaires, interviews, and think-alouds. The findings revealed that: (1) the proficient EFL readers judged themselves to be good readers, while the less proficient EFL readers judged themselves to be fair readers; (2) unknown vocabulary was perceived to be the major impediment to reading comprehension; the think-aloud data, however, demonstrated that unknown vocabulary did not significantly interfere with their reading comprehension; (3) regardless of the genre of the text, the participants employed similar reading strategies; (4) the participants were more likely to tolerate ambiguity and predict the content when reading the narrative text than the expository text; (5) there was no set of strategies that distinguished proficient EFL readers from less proficient EFL readers; and (6) when identifying problems, the proficient EFL readers used fix-up strategies more effectively and were better able to provide satisfactory solutions than their counterparts. Pedagogical implications for EFL reading instruction are discussed.

The purpose of this study is to propose the standards for dimension system for unit space of the classroom in elementary school. The curriculum of elementary school has changed. It has been reflected the architectural plan of classroom of the nationwide elementary school. However the Ministry of Education repealed the statue about the facilities of the schools on September in 1997 and the new education curriculum -the 7th curriculum- demands various activities in the classroom. So we need to another size of unit space of the classroom in elementary school because the size of unit space will affect the quality of education. This study represents that the size of unit plan is based on the size of human body, education curriculum, established day, the number limit of classroom and teaching tools. In this study, regression analysis is used to find out a part of the body-size of Korean.

As the learning space has expanded, the distance education has become a recent scholarship in teaching-learning method, and also a great type of media, technologies and strategies to support distance education are attracting a fair amount of attention. However in order to manage a distance education system, it is necessary to be endowed user with technical ability and operational expenses. On the other hand, although a web-based system that makes simple may cut cost, it is difficult to analyze learner's behaviors. Therefore, in this paper, we developed a interactive distance system based on individualized questioning, which relies upon learner's knowledge state and applies a efficient individualized learning method. Additionally, this study is instrument to reduce users' technical ability and operational expenses.
