The purpose of this study is to verify the effect of the method of English teaching and learning through the student-centered environmental instruction. I've been skeptical about the traditional instruction, which is composed of the teachers-centered instruction, because of the lack of creativity. Until now, I've always wished to have an alternative method that can be substituted for routine's style. To achieve it, I selected 90 students from 2 classes, in the 3rd year at a girls' high school in Chungnam as the subject of study. I divided them into two groups, the student-centered environmental instruction and the teacher-centered traditional instruction. The tools used in this study are a preliminary English achievement test, a self-directed learning attitudes test and two teaching plans. For this test, a high school text book was assigned. I have treated 20 times of the test each for two groups using two types of teaching-learning plans which I made for this purpose. To verify the hypotheses after administrating the test, I selected t-verification for post test result. Based on this test result, I could conclude that there was a significant improvement of English proficiency and a change in the self-directed learning attitudes; also the student-centered environmental instruction is more effective than teachers-centered instruction.

Relationships between immigrant mothers' Korean language ability and preschoolers' language development in multi-cultural families were studied with 91 mothers and their children. Language capacity of mothers and children was measured by receptive and expressive vocabulary test, sentence comprehension test and two kinds of reading tests. Results showed that mothers' level of comprehension was relatively low but their reading ability was higher than that of elementary school first-grade Korean students. Comprehension of children in multi-cultural families with non-immigrant counterparts showed a lower level of language ability. Mother's level of expressive vocabulary, receptive vocabulary and reading ability correlated with children's language development. These results indicate a relationship between children's delayed language development in multi-cultural families and mother's low proficiency in Korean language.

Many colleges in Korea have been making a concentrated effort to develop engineering certification education programs, fit for the certification standards and the reality of each college. However, in reality, many colleges and departments in Korea have great difficulties in making the curriculums meet the engineering certification standards to be proper for the present situation of each college. Therefore, this study aims at suggesting the most general way to make a specialized liberal arts curriculum for the colleges preparing for the engineering certification. When this is applied to the architectural engineering program curriculums of each college, students will be able to take specialized liberal arts subjects which are appropriate for their future careers and aptitudes, and also enterprises will be able to curtail educational expenses for their new employees and hire competent people who combine fundamental personality, basic knowledge about the work, and foreign language proficiency. Furthermore, the nation will be able to secure national competitive power through systematization of engineering education and realistic educational systems.

The purposes of the study are to introduce and apply an activity that can help improve student-initiated learning on the TOEIC Speaking Test (TOEICST) performance and to see students' attitude toward the activity. Twenty-eight university students in Chungcheong province engaged in learning based on this activity. In the present study, the activity proposed by McCormick and Vercellotti (2013) and Stillwell, Curabba, Alexander, Kidd, Kim, Stone, & Wyle (2010) was modified and adapted[14][19]. The outline of the Task Recording Activity (TRA) consisted of three steps: preparation step, Task Recording Activity step, and evaluation step. As data collection of the study, a survey and students' journal were utilized and qualitatively analyzed. The results showed that student-initiated learning activity could be applied positively not only in communicative lessons, but in TOEICST specific lessons as well. Additionally, participants showed positive attitudes toward self-transcription and self-correction. Some implications of the study are that the TRA can be applied to generate autonomous learners studying for the TOEIC Speaking Test, that the guideline for different proficiency can be developed to help them improve their self-reflection, and that students need to have an active attitude to lead their own learning.

This study seeks to validate the development and the effectiveness of a web-based online education program used to enhance communication skills of college students. Communication skills are important skills demanded of college students seeking employment that play a significant role in self-introduction, presentations, interviews, and continuous interaction in the workplace. 105 students in the third and fourth year of D University were selected for the experimental and control groups in which the experimental group met once a week for one semester in 2013 for a total of 16 weeks(twenty minutes) while the control group was left untreated. The variable of effectiveness for the results of this study was based on the criteria of communication and performance behavior skills. The results show that the communication skills and performance behavior skills proficiency of the experimental group compared to the control group, have made dramatic improvements. Therefore, the web-based communication skills training program for college students was found to be effective in the enhancement of the communication skills of college students. For the future, we expect further sustained development of various effective capabilities programs along with the promotion of web-based online education.

The purpose of the study is to research students' proficiency with systems-thinking approach concerning water cycles and to acquire data on Earth System-related concepts based on students' feedback. To achieve the purpose of the study, I chose 4 mid-level high school juniors living in Pohang, where the high school equalization policy has not been implemented, and the students answered a questionnaire about water cycles. Then, based on the results, I created a causal map and evaluated it using systems-thinking analysis. The results of the study are as follows: First of all, among the answers of the subjects, there were 21 concepts related to the conception of the earth system : 14 of the conceptions were linked scientifically, and 7 of the conceptions were not linked scientifically. Secondly, results of the causal map of what the subjects described showed that only two students'(A and C) feedback loops were completed, and that student C's feedback loop included unscientific reasoning. In conclusion, this study indicated that the students failed to understand the water cycle with the systems-thinking approach, or alternatively they applied low-level systems-thinking approach and had a lower understanding of it.

This study aims to develop performance criteria based on characteristics observed in science inquiry tasks for elementary school students. First, the performance characteristics by observing 70 fifth-grade elementary school students' science inquiry activity report are listed. Second, the checklist-type scoring criteria in connection with the theoretical framework of scientific inquiry process and relevant competencies are developed. Third, with the developed scoring criteria, 11 raters participate in scoring 350 students' reports. The main findings are as follow: first, the scoring data are well-fitted for the many-faceted Rasch model, and 22 scoring criteria are reasonably-well differentiated for various levels of proficiency. Second, at low performance level, observable characteristics are to answer questions explicitly required by the task or to observe objects or phenomena using pre-learned scientific concepts, while at high performance level, to explore additional data other than given data or to reflect on one's experimental process. Based on the results, the usefulness of analyzing students' performance characteristics for developing the scoring criteria, and further research directions are discussed.

TIMSS (Trends in International Mathematics and Science Study) aims to produce reliable and internationally comparable indicators of student achievement. The TIMSS science achievement scale summarizes student performance on test items designed to measure a wide range of student knowledge and proficiency. This study analyzed Korean middle school students' science achievement at the advanced and high international benchmarks of the four benchmark levels of the benchmarks classified in TIMSS 2003 in light of science content areas (physics, chemistry, biology, earth science, and environmental science) and item characteristics. The average percent correct on items at the advanced benchmark by Korean students was highest in physics followed by earth science, biology, chemistry, and environmental science, whereas internationally the order was earth science, chemistry, biology, physics and lastly environmental science. Korean students performed relatively better in physics yet somewhat worse in chemistry than other top-performing countries. According to item analysis, Korean students reaching the advanced international benchmark understood some fundamentals of scientific investigation, but demonstrated weakness in written explanations of scientific principles, abstract science concept comprehension, and application of scientific concepts to solve quantitative problems. In addition, Korean students reaching the high international benchmark demonstrated relative weak conceptual understanding of ecology compared with other countries.

A neural network is a modeling technique useful for finding out hidden patterns from data through repetitive learning process and for predicting target values for new data. In this study, we built multilayer perceptron neural networks for prediction of the students' computer literacy based on their personal characteristics, home and social environment, and academic record of other subjects. Prediction performance of the network was compared with that of a widely used prediction method, the regression model. From our experiments, it was found that personal characteristic features best explained computer proficiency level of a student, whereas the features of home and social environment resulted in the worse prediction accuracy among all. Moreover, the developed neural network model produced far more accurate prediction than the regression model.

Globalization brings changes to universities in particular facilitating internationalizing students exchange and curriculum diversification. Such efforts are relatively weak in education college even though the demands are high in students' global learning expectations internally and educational development cooperation from developing countries. The demands of global education arise from the increase of multi-cultural family, the compelling foreign language proficiency and others. The demands of development cooperation arise from the contribution of education to the rapid economic development. However, Korean participation focuses on vocational training which is far from the international norm of basic education provision and carried out without enough educational specialists. Global education and teaching practices in developing countries would substantiate the internationalization of education college while the effectiveness of educational development cooperation would be enhanced after learning the international norms and local knowledge which are learnt from the global education including foreign school practices.
