This paper is to help the students in elementary schools develop and improve their English listening and speaking skills by presenting effective teaching and learning techniques using puppetry. It is absolutely obvious that listening and speaking are very important skills for most EFL students. Using puppets in the classroom is a creative English teaching technique which can involve authentic, communicative language situations. Moreover, puppets appeal to children and can aid in lowering affective filters thereby creating a more comfortable learning environment. The study clearly showed that using puppets is feasible and enjoyable in elementary English classes. However, caution must be exercised in drawing and generalizing conclusions from this experience. The results of the experiment are as follows: First, using puppetry in the English class was found to have positive influence on students' affective domains (interst, attitude). Second, using puppets in the English classes was found to be efficient for improving students' English listening and speaking skills. Third, appropriate materials should be selected and well thought-out plans should be made to be successful English class using puppetry. Perhaps the most interesting line of future research is to use qualitative research to examine the effect of this technique on the teacher variable. Further research is recommended, especially on using puppetry for speaking proficiency and creating affectively comfortable learning atmospheres.

In this paper, we present a virtual laboratory platform (VLP) baptized Mercury allowing students to make practical work (PW) on different aspects of mobile wireless sensor networks (WSNs). Our choice of WSNs is motivated mainly by the use of real experiments needed in most courses about WSNs. These experiments require an expensive investment and a lot of nodes in the classroom. To illustrate our study, we propose a course related to energy efficient and safe weighted clustering algorithm. This algorithm which is coupled with suitable routing protocols, aims to maintain stable clustering structure, to prevent most routing attacks on sensor networks, to guaranty energy saving in order to extend the lifespan of the network. It also offers a better performance in terms of the number of re-affiliations. The platform presented here aims at showing the feasibility, the flexibility and the reduced cost of such a realization. We demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs.

Indoor air quality becomes of a concern recently in view of human health. This study investigates the air diffusion performance and the air change efficiency of a classroom, when outdoor air is introduced in addition to the heating/cooling operation of a ceiling-mounted heat pump. A CFD analysis has been performed to investigate the effect of the discharge angle of the air jets from the heat pump for both parallel and series types of outdoor air system. It is observed that the series type creates more uniform indoor environment compared to the parallel type in general. It can be concluded the discharge angle should not be larger than 40o for the parallel type, in order not to generate thermal stratification in the room.

The purpose of this research was to investigate meaning of teachers as they manifest themselves in the emotional regulation of 2year old infants in a daycare center. In addition, the research attempts to provide basic research data that can be used as a guideline for teacher's awareness, roles, attitudes, and classroom management for infant's emotional education in the future. To achieve this goal, participatory observation was conducted in a child care center class for infants under 2 years old from January 17 to January 29, 2012. The teacher is defined as follow : Teachers are authority figures whose image is that of absolute authority, and coupled with their dual role of passive caretakers. Additionally, they function as guides who guided infants through the process of emotional socialization, and played the central role of emotional contagion from whose expression speech and atmosphere the said infants receive much influence. Such results seemed to indicate that teachers today do not fully comprehend the importance of their roles in influencing the emotion regulation of infants.

In Korea, special education for the gifted is being activated in school systems, and many researches regarding this special education are being conducted. However, despite its rich research on the programs of this special education, there are almost no research on the institutions layout and spatial design that can utilize them. Considering the heat for education of the present and the researches on education for the gifted so far, this tendency is likely to continue. To study space composition and interior architectural design of children's institution for the gifted, we studied the cases of 5 institutions located in Seoul and the following are the results. The research results are as followed. Most institutions for the gifted used most common and technical paint, wallpaper, and PVC for finishing materials. The colors should be carefully selected, too, so that it will increase inquisitiveness and interest of the children, which will develop into creative ability. In the cases studied, color of most walls and furnitures were not very distinctive: they were in light pastel and bright tone. And there were set of desks in many shapes so it can be put in different ways for different purposes. However, there were also desks that are commonly used at schools, which were limited in arranging in various ways. Most cases studied were located in general building and therefore, natural light source was limited. On the part of appliances, supplements should be made so that classes can be carried out using multimedia materials.

Teaching orientations represent teachers' general way of conceptualizing their teaching. The orientations are regarded as a very important factor in developing teachers' pedagogical content knowledge because they often guide their instructional decisions such as the selection of contents and teaching strategies, the use of curricula materials, and the evaluation of learning. Thus, understanding teachers' orientations can provide meaningful suggestions to understand their instructional approaches and furthermore to enhance the quality of engineering education in college. The research question for this present study was what kinds of teaching orientations engineering professors possessed in teaching engineering courses and how the orientations were represented in their teaching. Six engineering professors, particularly interested in instructional approaches, participated in the research. The data sources included in-depth interviews with individual professors, classroom observations with field notes, and related documents. In results, four teaching orientations toward engineering courses were identified: 1) expert knowledge in engineering, 2) engineering practice, 3) social practice, and 4) interdisciplinary design. Individual professors had between one to three different teaching orientations. Even though the professors had similar orientations but their instructional strategies somewhat varied based on the disciplines.

Due to the development of technology even in learning and education area, many studies have begun to make a new attempts to research by using SNS, breaking away from traditional learning methods. However, the limitations of these studies are restricted only to the use of wireless Internet and writing on Web sites. This study aims to conduct a research on English learning activities that utilize various technologies such as Bigdata, Facebook, Social Network Services (SNS) and English applications. In addition, this study looks into how these modern technologies can be integrated in the classrooms and which activities can be applied in the English classroom. This research is to suggest effective English learning methods through a thorough investigation on the effectivity of various technologies based on the Web 2.0 such as Flickr, blogs, MySpace, and online discussion board within the context of the English learning. To verify the effect of the study, the subjects are divided into experimental and control group. The experiment is proceeded with pre- and post-test. The experimental group is designed to verify the effects using SNS tools such as Facebook, Bigdata, and Online Massive Learning. A survey is conducted to determine the preference of utilizing social networking sites and to analyze the effects in class. The result is that the average scores for experimental group have improved more than the average of control group. The comparison of pre and post-test of the experimental group shows that the significance of the higher and median group was statistically significant at the p<0.01.

We adopt a spirit of Problem based learning to the class of Multivariable Calculus in a school of scientifically talented students and observed effects of our teaching-learning method in the Spring Semester of 2010. Twelve students who enrolled in this class participated in this research. We have proceeded with classroom experiment for the half of semester after midterm exam so that the students could compare our teaching-learning method with usual traditional one in the subject of multivariable calculus. Especially, we investigated changes in the learning attitude and cognitive development of the students toward definition and theorem of mathematics. Each group of 4 students worked on a sheet of our well-designed structured problems of several steps in each class and presented how they understood the way of constructing new definition and related theorems. Instructor's role in this research was to guide students' activities as questioner so that students could attain the clear meanings of definitions and theorems by themselves. We firstly analyzed students' process of mathematization of definition through observing their discussions and presentations as well as their achievements in the quizzes and final exams. Secondly, we analyzed students' class-diaries collected at the end of each class in addition to pre/post surveys.

This research aims to take a close look at the following topics; the ground elevation of playground, equipments of playground, and equipments around playground, and to propose the improvement measure for favorable educational environment. In consideration of the needs mentioned, the following improvement measure for playground can be suggested. First, the elevation of playground should be changed. According to Environment psychology, current playground elevation should be lowered 2 stair-long height from a classroom site. This kind of elevation change can remove unnecessary stairs, and reduces inconvenience incurred by stairs and edges, which results in considerable educational finance saving. Second, the incidental equipment within a playground needs to be improved. This fact is found out at the surveyed schools; school gathering is held at classrooms (through broadcasting) or a multi-purpose auditorium in place of a playground. The results of this study make us conclude that the most important issue to be considered in the processes of selection and investigation for school playground elevation, incidental equipments and others.

Research and national standards, such as the Next Generation Science Standards (NGSS) in the United States, promote the development and implementation of K-12 interdisciplinary curricula integrating the disciplines of science, technology, engineering, mathematics, and computer science (STEM+CS). However, little research has explored how teachers provide epistemic support in interdisciplinary contexts or the factors that inform teachers' epistemic support in STEM+CS activities. The goal of this paper is to articulate how interdisciplinary instruction complicates epistemic knowledge and resources needed for teachers' instructional decision-making. Toward these ends, this paper builds upon existing models of teachers' instructional decision-making in individual STEM+CS disciplines to highlight specific challenges and opportunities of interdisciplinary approaches on classroom epistemic supports. First, we offer considerations as to how teachers can provide epistemic support for students to engage in disciplinary practices across mathematics, science, engineering, and computer science. We then support these considerations using examples from our studies in elementary classrooms using integrated STEM+CS curriculum materials. We focus on an elementary school context, as elementary teachers necessarily integrate disciplines as part of their teaching practice when enacting NGSS-aligned curricula. Further, we argue that as STEM+CS interdisciplinary curricula in the form of NGSS-aligned, project-based units become more prevalent in elementary settings, careful attention and support needs to be given to help teachers not only engage their students in disciplinary practices across STEM+CS disciplines, but also to understand why and how these disciplinary practices should be used. Implications include recommendations for the design of professional learning experiences and curriculum materials.
