It arises that teachers' professional competence should be considered not only with a cognitive perspective but also with a situative perspective. In this study, we considered mathematics teacher noticing as situational professional competencies of a mathematics teacher, and explored how mathematics teachers noticing on children's development of reasoning about variability in a video club has changed with the situative perspective. Findings illustrate that the 'interpreting' component among the three components of noticing-attending, interpreting, and deciding how to respond-was critically decisive for the change of the participant teachers' noticing. We also discussed how the video club intervention(the framework of children's development of reasoning about variability) can support the development of teacher noticing as a professional competence. This study has implications on the design of a video club to improve mathematics teacher noticing.

Computer with various powerful functions has profound potential for mathematics instruction and learning. As computer technology progress, its applicability to mathematics education become more comprehensive. Not only its functional development but various psychological positions also changed the way computer technology utilized in mathematics education. In behaviorist's perspective, computer viewed as a teaching machine and constructivist viewed computer as microworld where students could explore various mathematical contents. Both theoretical positions emphasized individual aspect of learning because behaviorist tried to individualize learning using computer and constructivist focused on the process of individual construction. But learning is not only a individual event but also a social event. Therefore we must take social aspect into account. This is especially important when it comes to computer based learning. So far, mathematics loaming with computer weighed individual aspect of loaming. Even in microworld environment, learning should be mediated by teacher and collaborative learning activities. In this aspect, the roles of teacher and peers are very important and socio-cultural perspective sheds light on the computer based learning. In socio-cultural perspective, the idea of scaffold is very important in learning and students gradually internalize the social dimension and scaffolding is gradually faded. And in the zone of proximal development, teacher and more competent peers guide students to formulate their own understanding. In sum, we must take following points into account. First of all, computer should not be viewed as a medium for individualized teaming. That is, interaction with computer should be catalyst for collaborative activities with peers. So, exploration in computer environment has to be followed by small group activities including small group discussion. Secondly, regardless of the role that computer would play, teacher should play a crucial role in computer based learning. This does not mean teacher should direct every steps in learning process. Teacher's intervention should help student construct actively. Thirdly, it is needed to conceptualize computer in learning situation as medium. This would affect learning situation and result in the change of pre-service and in-service teacher training. Computer to be used effectively in mathematics classroom, researches on assessment of computer based learning are needed.

The aim of study was to identify factors influencing the self-confidence in the teacher's role on adolescent suicide. The cross-sectional descriptive study design was used. Participants were 318 teachers from elementary, middle, and high school in D city. Data were collected using questionnaires which included general characteristics, attitude toward adolescent suicide, knowledge about guideline for adolescent suicide prevention, and self-confidence in the teacher's role on adolescent suicide. Collected data was analyzed using descriptive statistics, t-test, Pearson correlation coefficient, and multiple regression with SPSS 21.0 program. The results of the regression analysis revealed that experience of suicide education, attitude, and knowledge about adolescent suicide were the significant factors affecting the self-confidence in teacher's role for adolescent suicide. The predictor variables explained 22.5% of variance regarding self-confidence in teacher's role for adolescent suicide. Findings indicate the factors should be used in developing effective intervention for enhancement of self-confidence in teacher's role on adolescent suicide.

Objective: This study designed an Augmented Reality-based intervention program for children with conflicted shyness and examined its effects on social avoidance motivation and preference for being with others. Methods: Sixteen six-year-old children were randomly assigned to either the experimental or control group. The experimental group participated in a six-week AR-based program. Both teachers and children rated social avoidance motivation and preference for being with others to evaluate the program's effectiveness. Data were analyzed using the Wilcoxon signed-rank test and the Mann-Whitney U test. Results: Social avoidance motivation decreased only for the experimental group. Conversely, the control group showed increased motivation scores as reported by the children. The preference for being with others increased in the experimental group based on teacher reports. For the control group, preference scores reported by teachers and children were maintained and decreased, respectively. Conclusion/Implications: This study highlights the effectiveness of the intervention in reducing social avoidance motivation and maintaining a preference for being with others in children experiencing conflicted shyness. Furthermore, the use of AR technology provided a psychologically safe environment for them to initiate social interactions without fear of negative evaluation, highlighting its potential as a primary intervention tool for this population.

The purpose of this paper is to compare and analyze the two different teaching methods of elementary mathematics in the traditional method and in the constructive view. To do so, the actual class in the constructive view has been made for about four months using a class of 45 students in the second grade of an elementary school. After the class was finished, we collected diverse data from the class, such as the responses from the children(self-evaluation, mathematics diary, observation by the investigator, daily report), class evaluation report by other teacher and so on. The results of this research are as follows: First, the traditional class reaches at the goal of learning in a unit time because the class is guided by the teacher but the class in the constructive view is a little flexible because it is contextual. Second, in the constructive process of mathematical knowledge we knew that small group activities or discussion without intervention of teacher was often ended in exhaustive argument without arriving at valid social consensus. Third, the attitude in mathematics was changed from the passive one to the self-regulated ones. Fourth, the class in the constructive view could extend not only the ability of mathematical communication but also the ability of self-directed learning of children. Fifth, it was a considerable change the role of teacher, that is, guide of instruction instead of unique specialist in the classroom. Sixth, finally, the evaluation was made after finishing a unit class in the traditional instruction but it was integrated in a class in a constructive view.

This study examined pre-service science teachers' perceptions of informal learning by adopting a discourse analysis method suggested by Mortimer and Scott(2003). The guiding research questions were: (1) What are some general patterns of the discourse occurring in science museums between a teacher and a student? (2) In what ways do the pre-service teachers perceive informal learning and teacher's role in informal settings? The 7 pre-service science teachers participated in this study. Each of them shepherd an elementary student around the museum and implemented their own instruction using a pre-planed lesson plan. Results indicated that even though the teachers had learned some characteristics of informal teaming in their college courses, they tended to implement their traditional view of science teaming into the instruction and the view affected them to set up their teaching purposes and contents, and to select communicative approach, patterns of discourse and ways of intervention.

In present study, using 1572 low-income families and 266 Head Start teachers from Family and Child Experiences Survey (FACES) in the U.S., we examined the effects of mothers' reading and the characteristics of interaction between teacher-child interaction on 4-and 5-year-olds' cognitive development represented by their verbal and numerical abilities. Frequencies of mothers' reading at home consistently predicted higher scores of children's Peabody Picture Vocabulary Test and Woodcock Johnson Applied Problems. Teachers' sensitivity and permissiveness in their interactions with children in classroom were positively related to children's verbal abilities and teachers' sensitivity predicted better numerical abilities of children after controlling for mothers' reading and the characteristics of family and teacher. The findings shed light on the contributions of teacher behaviors and familial factors to children's cognitive development calling for attention to the need for parent education on cognitively stimulating family environments and continuing education for early childhood teachers focusing on quality interactions with young children.

Applied Behaviour Analysis (ABA) is the applied science where strategies are derived from the principles of behaviour and are applied to improve meaningful social behaviours [3]. This study investigates the possible inclusive value of the use ABA in schools in Saudi Arabia. Interviews were conducted with two ABA therapists and a support teacher in order to address this possibility. From the research findings, it emerged how ABA is one of the cognitive-behavioural intervention models and therefore, can be generalised to other disorders or diagnoses and the applied behavioural analysis does have an inclusive value as it structures individualized activities for the increase of both personal and social skills and these activities allow the subject to work on his or her skills, which are, however, absolutely preparatory to the inclusion of the subject in the classroom context.

Objectives: The present study was carried out to develop and evaluate comprehensive health care program to prevent infectious disease and promote health in child-care centers by Doctor of Korean medicine. Methods: A nonequivalent control group pretest-posttest design study was conducted on 568 children and 85 child care teacher at 12 child care facilities for 12 weeks from July to October 2012. The program was consist of management, education, screening under concepts of traditional preventive medicine, Yangsaeng and Chimibyeong. Children's medical utilization due to infectious disease and attendance means functional status were measured by reports from parents. The Difference in difference(DID) estimator was applied data analysis, and added Zero-inflated negative binomial regression model. Also, attitudes on the infection of teacher was measured and analyzed through t-test. Results: After the intervention, the total medical utilization due to infectious disease decreased, but not significantly. Total absence, early leave and lateness decreased significantly. But, Attitude on the infection of child care teacher was not changed. The parent's satisfaction showed positive overall. Conclusions: The intervention program may be effective in preventing infectious disease and managing health in child-care center partially. To measure long-term effect, long-term study improved is requested.
