  • 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 two different ways 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.

  • Mathematically, a proof is to create a convincing argument through logical reasoning towards a given proposition or a given statement. Mathematics educators have been working diligently to create environments that will assist students to perform proofs. One of such environments is the use of dynamic-geometry-software in the classroom. This paper reports on a case study and intends to probe into students' own thinking, patterns they used in completing certain tasks, and the extent to which they have utilized technology. Their tasks were to explore the shape-to-shape, shape-to-part, and part-to-part interrelationships of geometric objects when dealing with certain geometric problem-solving situations utilizing dissection-motion-operation (DMO).

  • In Jamaica Kincaid's novel Lucy, the narrator grows up with the burden of colonial legacies embedded with Englands' imperial disciplinary projects, its language, educational institutions, discourses. Colonial education interpellates the narrator into a colonial subject through its multiple ideological discourses and systems. Teaching the literature of England is the most insidious form of the Empire's disciplinary colonial projects, more powerful than military enforcement: Its mode of operation is creating phantasy and instigating and planting desire for such phantasy. As Homi Bhabha aptly theorizes as colonial mimicry and ambivalence, the narrator as colonial subject grows up split and confused as an ambivalent subject, simultaneously mimicking and desiring for the phantasized England as real, while resisting and criticizing such up-bringing and mimetic desire. This paper explores Kincaid's rhetorical strategy of employing Wordsworth's poem, "I Wandered as a Lonely Cloud," especially her use of the flower "daffodil." Employing the concept of "daffodil gap" suggested by postcolonial critics, this paper closely examines two episodes involving the flower daffodil in the novel, one in a colonial classroom and the other in a garden in a new world and suggests that Kincaid accomplishes intertextual critique of colonial education and imperial projects.

  • The aim of this study is to provide practical instances of implementing picture book reading sessions within school libraries to enhance language proficiency and foster emotional stability among lower-grade multicultural students hailing from foreign backgrounds. The research outlines the design and execution of a picture book reading program tailored for multicultural students, with analysis based on the outcomes of actual classroom implementations. In the course of the study, existing literature pertaining to the use of picture books for enhancing multicultural education and language skills was reviewed. This informed the development of a structured class procedure by extracting core components. Indeed, 43 multicultural students in five classes in the first and second grades of A Elementary School in Gyeonggi-do were given three pilot classes for each class for 20 weeks and a total of 100 picture book reading classes, each with 17 main lessons. This study establishes the positive impact of picture book reading classes on the Korean language comprehension of multicultural students. The results confirm positive improvements in students' ability to understand Korean, as evidenced by enhanced Korean expression and presentation skills, increased library usage, and a positive shift in classroom attitude. The procedure for reading picture books using school libraries proposed in this study was actually conceived and developed in the course of class operation in the school education field, reflecting the changes brought about by the increase of multicultural students and the need to improve the class environment. Through this practical investigation, important insights have been extracted regarding how picture book reading sessions designed for elementary school students from multicultural backgrounds can enhance the classroom environment and elevate learning outcomes.
