The purpose of this study is to design and implement an instructional model for flipped learning of programming class. Because a programming process requires a high level of abstract thinking with a good understanding of a programming language, many students have difficulty in programming. For this characteristic of programming, it is not easy to effectively achieve learning goals of programming lesson by lecturing grammatical elements of a programming language and the following examples in a limited class time. In order to overcome these problems and to make effective programming lessons, we designed an instructional model based on flipped learning. Especially, in this study, we analyzed learners' difficulties in programming learning and errors that occurred in actual programming process for designing the instructional model. As a result of applying this model to the class, it was found that the students were generally satisfied with the lesson by having positive communication with other students in the classroom and actively participating in the learning.

The purpose of this study is to develop an effective teaching model for the "Problem solving methods and procedures" section in the revised academic high school informatics curriculum, verify its effectiveness, make the subject more effective and appealing to teachers as well as students. The model includes a middle school level informatics curriculum for the students who have yet to learn the section. This development follows the ADDIE model, and the Python programming language is adopted for the model. Using the model, classes were conducted with two groups: high school computer club students and undergraduate students majoring in computer education. Of the undergraduate students 75% responded positively to the model. This model was applied in the actual high school classroom teaching for 23 class-hours in the spring semester 2012. The Pearson correlation coefficient that verifies the correspondence between the PSI score and the informatics midterm exam grade is .247, which reflects a weak positive correlation. The result of the study showed that the developed teaching model is an effective tool in educating students about the "problem solving methods and procedures". The model is to be a cornerstone of teaching/learning plans for informatics at academic high school as well as training materials for pre-service teachers.

이 논문은 한국어 관계관형절(relative adnominal clause)의 전산처리에 적합한 통사 의미 표상 모형을 제시하고, 그 결과를 전산적 구현을 통해서 검증하는 것이 목적이다. 이를 위해 이 논문에서는 다음의 두 가지 문제를 중심으로 관계관형절의 통사 의미 표상과 전산적 구현 문제를 다룬다. 첫째, 관계관형절의 수식을 받는 머리 명사(head noun)는 관계관형절과 모문(matrix sentence)에서 각각 다른 의미역할을 하는 논항이다. 즉, 하나의 논항이 두 개의 의미역을 표상한다. 이 논문의 첫째 과제는 이러한 관계관형절 구문에서 머리 명사의 이중의미역을 표상하는 방법을 모색하는 것이다. 둘째, 관계관형절이 일항술어로 구성될 때, 서술어 단독으로 머리 명사를 수식할 수 있을 뿐만 아니라, 주격중출 구문을 관계화하여 미리 명사를 수식할 수도 있다. 그러나 모든 일항술어가 주격중출 구문을 구성할 수 있는 것은 아니기 때문에 주격중출 구문의 관계화가 가능한 경우와 그렇지 않은 경우를 구별할 필요가 있다. 이 논문의 둘째 과제는 이러한 주격중출 구문의 관계화와 그 표상의 문제를 다루는 것이다. 이 논문에서는 이러한 문제들을 단순히 기술하는 데 그치지 않고 전산 구현을 통해 문제해결을 제시한다. 이를 위해 구현 도구로 C-언어를 보강하여 개발한 문법개발 도구언어인 말라가(Malaga)를 사용하며, 분석결과를 자질구조(feature structure)로 명시하여 그 타당성을 검토한다.

The purpose of this study is to investigate the characteristics that indicate scientifically gifted students by analyzing the verbal interactions in developmental biology inquiry-experimental classes. The subjects were 20 first-grade middle school students who were participating in SNU Science Gifted Education Center. In these experimental classes which were developed based on the CPS Model, we conducted a total of four experimental sessions of small group discussions, and the students' verbal interactions were both taped and video recorded, and observed. From the transcriptions, the patterns of question-answer and the characteristics of scientifically gifted students were analyzed. In the case of question-answer patterns, thinking questions appeared 3~6 times more frequently than the standard information questions. Especially, the case of experimental class I showed 40% more thinking questions as well as standard information questions that the other 3 classes. Through the results of analysing verbal interactions, we were able to find more detailed aspects to creativity that were not identifiable in paper-pencil examinations, as well as affective characteristics such as task commitment and leadership. We believe our findings upon inquiry will be of substantial significance in substituting for the paper-pencil examination in distinguishing and selecting scientifically gifted students.

This study aimed to empirically analyze the factors influencing the career search intention of college students. The research model was derived based on the Social Cognitive Career Theory (SCCT), considering the unique characteristics of university students. Self-efficacy and outcome expectations were investigated as independent variables, while mastery experience, verbal persuasion, vicarious learning, and positive emotions were considered as antecedent variables. A survey was conducted among college students in the metropolitan area, resulting in 217 valid responses for analysis. Empirical analysis was conducted using structural equation modeling with AMOS 24. The findings revealed that mastery experience, vicarious learning, and positive emotions had a significant positive effect on self-efficacy. Furthermore, verbal persuasion and positive emotions significantly influenced outcome expectations. However, the impact of verbal persuasion on self-efficacy was not found to be significant, and the relationship between mastery experience, vicarious learning, and outcome expectations was not examined. Both self-efficacy and outcome expectations were found to have a significant positive effect on career search intention, with outcome expectations exhibiting a stronger influence. The empirical results contribute to the understanding of college students' career exploration and provide implications for academic and practical contexts.

What is the reason that the use of an Information Processing Model (PM) contributes to enhancement of students' creativity? Postulated creativity is generated from integration of information, the author discloses the function of a human information processing system and an IPM is an integrating process of information which produces creativity. Also the use of IPM as a tool influences favorably the integration of information within the human thinking system because the function of psychological tool helps the integration of information that produces creativity.

A GRId-based Soil MOsture Routing Model(GRISMORM) which predicts temporal variation and spatial distribution of water balance on a daily time step for each grid element of the watershed was developed. The model was programmed by C-language which aims for high flexibility to any kind of GIS softwares. The model uses ASCII-formatted map data supported by the irregular gridded map of the GRASS(Geographic Resources Analysis Support System)-GIS and generates daily or monthly spatial distribution map of water balance components within the watershed. The model was applied to Ipyunggyo watershed(75.6$km^2$) ; the part of Bocheongchun watershed. Predicted streamflows resulting from two years(95 and 96) daily data were compared with those observed at the watershed outlet. The results of temporal variation and spatial distribution of soil moisture are also presented by using GRASS.

The purpose of this study is modeling a user-friendly Korean-Japanese thesaurus for internet circumstances. The methodology had two steps: first, the problems were analyzed when multilingual thesaurus is constructed, with review of various multilingual thesauri and interview with multilingual thesaurus constructor in Korea and Japan. Second, collaborative tags were analyzed to differentiate cultural/linguistic background from word usage pattern. As a result, searching thesaurus model was suggested and applied to develop a user-friendly Korean-Japanese thesaurus.

It is possible to solve many structural problems such as the occurrence of a lot of errors involving misspelling which may occur during the learning of existing programming language, difficulty in grammatical expression and understanding, and difficulty in the expression of algorithm if the program learning tool of the department of computer education in a college of education is utilized as an educational robot. This study developed a learning model (curriculum and a textbook) so that students who major in computer education may easily learn programming by using the NXT software of a Mindstorms robot.
