In this study, I investigate the literary features and educational values of spoken travelogues by analyzing a travelogue about the Diamond Mountains by a farmer named Im, Chul-ho, a very interesting travelogue told for 70 minutes. It seems to have educational significance as a wonderful piece of literary work. The literary features of this tale can be summarized as follows. (1) It is truly 'literature of reality' which fully brings out literary appreciation; It evokes interest and emotional tension on the part of audience through vivid verbal embodiment of personal experiences; (2) It is a well constructed big story embedding small stories within it. The stories from many different travel points emerge into a whole unified story making it much richer and more attractive; and (3) It truly reflects the experiences and emotions of ordinary people. As such, it can be regarded as their spiritual property. In addition, spoken travelogues could be valuable as an object in literature education. It needs to be included in the literature curriculum and treated in the same way as written travelogues. With strengths as instructional materials, it could be effectively used to improve students' ability to express their daily experiences with literary sensibility and to make them better understand the lives of ordinary people in the past.

This qualitative research describes unique features of seven exemplary science teachers' professional development activities. Description of excellence in effective teachers' professional development efforts will provide some insights into required inservice initiatives and support systems for teachers' professional learning. Exemplary science teachers' professional development activities can be classified into four types: (1) practicing classroom supervision, (2) participating in voluntary communities of teachers, (3) playing instructional leader roles in teacher training programs, and (4) continuing one's studies at a graduate school. One of the common features of these exemplary teachers was that they can both articulate what makes teachers professionals and practice in accordance with their perspectives. These exemplary teachers not only improved their own classroom practices, but also participated actively in various professional communities to share their practical knowledge with their colleagues. The teachers have formed special-interest groups to investigate better ways of science teaching. They also took an active role in teachers' in-service education. Teachers' quality practices lie at the heart of classroom change. However, it's important to remember that there must be a support system that sustains and encourages teachers' initiatives. The implications for the support system to encourage teachers' professional development efforts are discussed.

Intelligent tutoring system enables users to effectively learn by utilizing various artificial intelligence techniques. For instance, it can recommend a proper curriculum or learning method to individual users based on their learning history. To do this effectively, user's characteristics need to be analyzed and classified based on various aspects such as interest, learning ability, and personality. Even though data labeled by the characteristics are required for more accurate classification, it is not easy to acquire enough amount of labeled data due to the labeling cost. On the other hand, unlabeled data should not need labeling process to make a large number of unlabeled data be collected and utilized. In this paper, we propose a semi-supervised learning method based on feedback variational auto-encoder(FVAE), which uses both labeled data and unlabeled data. FVAE is a variation of variational auto-encoder(VAE), where a multi-layer perceptron is added for giving feedback. Using unlabeled data, we train FVAE and fetch the encoder of FVAE. And then, we extract features from labeled data by using the encoder and train classifiers with the extracted features. In the experiments, we proved that FVAE-based semi-supervised learning was superior to VAE-based method in terms with accuracy and F1 score.

This study analyzed universities's entrepreneurship education curriculum and variety programs through visiting to five entrepreneurship centers. Through these analyzes, the study presents a basic frame work for prosperous entrepreneurship education in Korea. We have selected for visiting research universities in the middle east of the United states; University of Iowa, University of Missouri(Kansas City), Saint Louis University, University of Louisville and George Washington University. We visited entrepreneurship center of each university in order to have in-depth interview with professor who is responsible for building entrepreneurship curriculum and administrative director of entrepreneurial programs so that we research how university progresses entrepreneurship education at undergraduate level. The study, at the time of 61 universities selected for LINC project by the Korea Ministry of Education who expects Industrial-Academia cooperative effects just installed each entrepreneurship center, analyzed case study of operational practice and entrepreneurship education curriculum for the effective operation of entrepreneurship centers in universities. We believe that the study will be able to provide a richer and more accurate information and ideas since the all the analysis is based on the firsthand interview by visiting.

In this study, it is assumed that understanding the nature of science (NOS) would enhance students' performance of scientific inquiry in more authentic ways. The ultimate goal of this study is to suggest new models for developing scientific inquiry activities through understanding the NOS by linking the NOS with scientific inquiry. First, the various definitions and statements of the NOS are summarized, then the features of the developmental nature of scientific knowledge and the nature of scientific thinking based on the philosophy of science are reviewed, and finally a synthetic list of the elements of the NOS is proposed, consisting of three categories: the nature of scientific knowledge, the nature of scientific inquiry, and the nature of scientific thinking. This suggested synthetic list of the NOS is used to suggest a model of scientific inquiry through the understanding of the NOS. This list was designed to provide basic standards regarding the NOS as well as practical guidance for designing activities to improve students' understanding of the NOS.

One of the most important features in the 7th National Curriculum of English is the introduction of the middle school multi-purpose English classes. Despite the importance of the classes, there doesn't seem to be enough studies of developing learning materials for them. The purpose of the current study is, therefore, to develop English learning materials for the multi-purpose English classes based on the Task-Based Learning framework. To do so, various tasks were collected and adapted for the classes, and different teaching techniques suitable for the tasks were designed. It is hoped that this research will help teachers prepare for teaching materials for the classes, and students recognize their interests in English and to improve their English abilities.

The 7th National Education Process, implemented in 2004, features student-oriented, selective educational programs with a wide range of optional subjects. In 2005, reflecting this revised National Education Process, the College Scholastic Ability Test began allowing individual students to choose the subjects for examination they would like to take. As a result, the deviations of the college freshmen's academic achievements in some subjects have noticeably widened. This study shows academic abilities of the students on some subjects by comparing the results of 2008 College Scholastic Ability Test with that of the Basic Academic Ability Evaluation Test for freshmen in engineering college of Hongik university. Lastly, this paper presents some improvement plans in order to better accommodate students with academic achievement levels lower than what is expected by the university.

This paper is to introduce assorted features of a four-week English Immersion Program managed by Hongik English Language Institute for the first time in summer 2000. The program was aimed to provide English learners with the English simulation environment where everything was supposed to be English only. Thus being exposed exclusively to the English surroundings the clock around, the learners who had not had enough opportunities to use the language were able to attain a high motivation for speaking English, which eventually led to the increase of their general English language proficiency. Presenting merits and demerits of the curriculum and the overall management of the program, this paper plays a role in directing the program in a more improved way for the future and giving guidelines to other institutes where similar programs are under consideration.

The object of this study is to introduce a new subclass of univalent analytic functions on the open unit disk. This subclass is created by utilizing univalent analytic functions with negative coefficients. We first explore the specific properties that functions in this subclass must possess before examining their coefficient characterization. By applying this approach, we observe several fascinating features, including coefficient approximations, growth and distortion theorems, extreme points and a demonstration of the radius of starlikeness and convexity for functions belonging to this subclass.

This paper reports on an identification test where KFL learners identified the Korean three-way laryngeal contrast in the phrase-initial position, when the phrase-initial tone was systematically manipulated. It turns out that heritage learners have some sensitivity to phrase-initial tone and show a plain-aspirated alternation in their identification according to the phrase-initial tone, as native speakers do, whereas non-heritage students do not show such tone sensitivity. However, after a weekly prosody training, second-year non-heritage students have shown a significant improvement in their performance. This paper clearly shows that the phrase-initial tone plays a critical role in distinguishing laryngeal features of Korean obstruents, and also suggests that prosody including the tone-segment correlation should be incorporated in the KFL curriculum.
