This paper emphasizes the effect of using poetry in the University General English education and suggests the teaching method of English education with a Frost's poem, "Out, Out- ." These days, learner-centered English education and integrative study of four linguistic functions, reading, listening, speaking and writing are considered important in the University General English class. Poetry is very effective text for the education purposes. Poetry techniques like a visual image, rhythm, rhyme, or repetition are actually mnemonics and strongly connected to the enhancement of memory and oral linguistic function. This paper suggests the specific education methods in the poetry selection, pre-reading step, reading step and after- reading step with concrete examples of "Out, Out-." These education methods through the 'oral text' can be a good and sustainable model for learner-centered education.

The purpose of this study was to investigate the effects of the Science Writing Heuristic (SWH) teaching strategy on cognitive levels, science concept understanding, argumentation and writing skills. 131 students attending to co-ed middle school were selected for the study and assigned to the experimental and comparative group. The teaching strategy using SWH was applied to the experimental group, while the traditional one led by teacher's lecturing was applied to the comparative group. The cognitive level test (SRT II) and baseline test were administered before the instruction period. The summary writing test and SRT II test were administered after instruction. The results showed that there was a significant difference between two groups in cognitive levels and science concept understanding, whole argumentation and writing skills. However, there was no significant difference in some argumentation components, including warrant, backing, qualifier, rebuttal, metacongnitive question. The results of this study showed the possibility of implementation of SWH in science classroom teaching.

This study tries to present a new perspective for the coding and coding education. Therefore, this study analyzes coding game as performative writing. First, coding as writing process has the mechanism of serial expansion and circulation by utilizing basic code blocks. And coding as writing process produces a meaning as unit operation that generate an emergent game play. Second, coding as performative writing displays the speaking and writing at the same time and is embodied in game play. Also, absence of failure and correction makes possible users to explore the problem area and to strengthen the problem-solving ability.

Thrust measuring is one of the crucial factor to decide the performance of a liquid rocket engine when the engine development test, especially for the combustion chamber, is implemented. Calculating the thrust from a combustion pressure is used when direct measuring the thrust is impossible, but direct measuring the thrust is necessary and various methods for doing it more precisely should be considered. This paper introduces the preliminary design concept about the new thrust measurement system for the vertical firing test stand, which is introduced domestically for the first time, of a liquid rocket engine combustion chamber.

This paper suggests a class model to improve the English oral proficiency for intermediate low English speaking learners. Utilizing the four English skills (reading, writing, listening and speaking), the class model focuses on the learners' schema and discussion strategies. To enhance the learners' motivation and match their cognitive capacity, 10 discussion topics were prepared by surveying the learners. A pilot experiment was conducted to investigate the teaching effects of the discussion class model with 26 college students majoring in English in Seoul. The participants' oral proficiency was measured both before, and after the instructions by OPIc (Oral Proficiency Interview in computer). As a result of the experiment, the percentage of participants whose oral proficiency levels were lower than intermediate mid decreased from 82% to 47%. In addition, the percentage of participants with higher oral proficiency than intermediate low was increased dramatically from 18% to 53%, which supports the claim that through discussion, the class learners' diverse and creative ideas need to be expressed in a formal and intelligible language. Finally, through the findings of the study, the possibility of a discussion class can be expected, regardless of the learners' low level of oral proficiency.

The purpose of this study was to examine the social efficacy of children shown in reflective journal writing of early childhood education teachers focusing on picture book activities. The subjects were 47 3, 4 and 5 year old children in G Child Care Center in the Capital Area. Teachers were asked to do 20 picture book activities and to write a journal according to reflective thinking after each picture book activity. Through the reflective journals collected, this study attempted to interpret and analyze them qualitatively by classifying the journals and yielding text contents according to factors for children's social efficacy such as emotionality, emotion control, interpersonal relationship technique, and social knowledge understanding. From the results of this study, first, it was found that children expressed their emotion naturally and that they learned their unique emotionality while they lived together with their friends. Second, it was found that children perceived and controlled their own emotions by using their sympathy and empathy. Third, it was found that children recognized and accepted that they are different rather than the counterparts are wrong through their differences in each other's thoughts to compose the capability of interpersonal relationship. Fourth, it was found that children improved themselves by their understanding, respecting and accommodating their friends as members of society.
