In this paper, we try to criticize a bias that liberal arts are not practical. First, I introduce holistic models of knowledge and constructivism in education. Second, I suggest 'linguistic turn' as another noticeable phenomenon. Language is an element of culture, but a priviledged one because culture, in itself, is linguistic. So culture is a sort of a text. We can see that liberal arts or humanities to deal with texts, contexts and languages can have an important role to read, understand and construct a world. So the rediscovery of the traditional model of the education of liberal arts like processes of graduating studies of liberal arts or humanities, is relevant to a new 'practical' model of reading and leading recent social transformations. An important point is academic contribution. And current situation called 'Knowledge-Based Society' also supports my point in another way. The situation of rapidly changing knowledge requires an education of problem-solving ability by unifying and reconstructing knowledge supporting with constructivism in education rather than the cramming system of education.

This study investigated the effects of drawing and writing as methods to assist students in connecting and integrating multiple external representations provided in learning the particulate nature of matter. Seventh graders (N=224) at a coed middle school were assigned to a control group, a drawing group, and a writing group. The students were taught about "Boyle's Law" and "Charles's Law" for two class periods. Students observed macroscopic phenomena through experiments. After this observation, students in the control group learned the topic with both external visual and verbal representations simultaneously. Students in the drawing group drew their mental model from the external verbal representation provided, and then compared their drawing with external visual representation. Students in the writing group wrote their mental model from the external visual representation provided, and then compared their writing to the external verbal representation. The two-way ANCOVA results revealed that the scores of a conception test for the writing group were significantly higher than those for the control group. While the drawing group performed better than the control group, the difference is relatively smaller. There were no significant interactions between the instruction and spatial visualization ability in the scores of the conception test. Most students perceived the writing or drawing activities helpful in understanding the concepts, and a few students responded that the writing or drawing activity was interesting. Educational implications were discussed.

The purpose of this study is to examine the students' and teachers' perception about the roles and qualifications of teacher librarians. For this purpose, data were collected through survey from students and teachers at secondary schools and the data were analyzed by semantic network analysis. The results of the research are as follows: First, students usually perceived the role of teacher librarians as 'library management', and teachers did as 'reading education'. Second, among the roles of teacher librarians, it was confirmed that students' and teachers' perceptions of 'information literacy instruction and library instruction' were very weak. Third, while the students' perception of the role of a teacher librarian as a 'teaching collaborator' such as 'teaching and learning support' and 'library assisted instruction and collaborative instruction' was weak, teachers recognized the role of teacher librarians as 'teaching collaborators'. Fourth, students and teachers perceived high levels of 'information service', which consists of 'book recommendation and guide activities'. Finally, it was investigated that 'professionalism' plays a central role in the students' and teachers' perception about the qualities of teacher librarians. These results can be used to establish the role of teacher librarians, develop response strategies for students and teachers, and improve their awareness.

The purposes of this study were to develop and implement a teaching strategy that reinforced teacher-student interaction for middle school first grade science and investigate the impact of the teaching strategy on student comprehension of scientific concepts, logical thinking ability, and science-related attitudes. 200 students attending a co-ed middle school located in Gyeonggi province were selected for the study and divided into an experiment and control group each consisting of 100 pupils. The teaching strategy reinforcing teacher-student interaction was applied to the experiment group, while conventional teaching, teacher-led lecturing, was carried out on the control group. To accomplish reinforced teacher-student interaction teacher asked students diversified questions and gave delayed feedbacks that deliberately focused on thought provocation. Results showed that the developed teaching strategy was effective in improving the students' logical thinking ability(p<.01). However, no significant differences were found in student comprehension of scientific concepts and science-related attitudes between the experimental and control group(p<.05). It was determined that more sound research is needed to develop and apply a lesson plan based on the teaching strategy used in this study.

The educational courses for the procedural-oriented and object-oriented programming languages have been prepared respectively in many universities. However, the comparison of two languages has not been shown in the same class. In this paper, we compared two distinctive languages, C and Java, and developed a new class material and the relating web contents, through which those who are interested may maximize their understanding and programming skills based on the different programming language.

This paper is proposed to present elementary algorithmic thinking-based Squeak E-toy programming problems for flowchart-based programming educations without programming languages in elementary programming educations. Furthermore, this paper proves the validity and effects of developed Squeak E-toy programming problems through measurement analyses of metacognition and GALT logical thinking ability experiments by comparing with the language-based traditional programming education.

본 연구에서는 명지전문대학에서 시행되고 다양한 학습지원 프로그램을 프로그래밍 언어 수업에 적용하여 운영하였던 사례를 제시하고 학습자 의견 및 만족도를 조사하였다. 학습지원 프로그램의 참여는 자발적으로 이루졌으며, 분석 결과 전반적으로 학습자들은 학습지원 프로그램에 대해 만족하는 것으로 나타났고, 참여 학습자 그룹의 성적이 비참여 학습자 그룹보다 좋은 것으로 나타나 학습지원 프로그램이 학습에 도움이 됨을 알 수 있었다. 또한 참여 프로그램에 따라 학습자들의 참여 목적과 참여를 통해 얻은 좋은 점은 다른 것으로 나타났고 비참여 학습자들의 참여하지 않은 이유가 프로그램 운영 환경과 관련이 있는 것으로 나타나 학습지원 프로그램의 효과적인 활용을 위해서는 학습자의 학습 목적에 따라 참여 프로그램을 제안할 필요가 있음을 알 수 있었다.

본 논문에서는 텍스트 마이닝 기반의 토픽 모델링 웹 애플리케이션 모델을 제안한다. 웹크롤링 기법을 활용하여 키워드를 입력하면 요약된 논문 정보를 파일로 저장할 수 있고 또한 키워드 빈도 분석과 토픽 모델링 등을 통해 연구 동향을 손쉽게 확인해볼 수 있는 웹 애플리케이션을 설계하고 구현하는 것을 목표로 한다. 제안 모델인 웹 애플리케이션을 통해 프로그래밍 언어와 데이터 분석 기법에 대한 지식이 부족하더라도 논문 수집과 저장, 텍스트 분석을 경험해볼 수 있다. 또한, 이러한 웹 시스템 개발은 기존의 html, css, java script와 같은 언어에 의존하지 않고 파이썬 라이브러리를 활용하였기 때문에 파이썬을 기반으로 데이터 분석과 머신러닝 교육을 수행할 경우 프로젝트 기반 수업 교육 과정으로 채택이 가능할 것으로 기대된다.

The purpose of this study was to develop and evaluate practical problem-based Home Economics lesson plans applying to the multiple intelligence teaching learning strategy, focused on the unit 'Nutrition & Meals' of middle school Home Economics subject matter. To achieve this purpose, the lesson plans were developed and evaluated from the 72 middle school students in Chongju after implementing the instruction. The data from the questionnaire were analyzed by SPSS/WIN 12.0 and content analysis. The results were as follows: First, the objectives of practical problem-based 'Nutrition & Meals' Instruction using multiple intelligence teaching strategy were to understand the importance of nutrition and health in an adolescent period and to develop good eating habits. The Practical Problem was 'What should I do for good eating habits?' and the learning contents were healthy life, the kinds and functions of nutriments, food pyramid and a food guide. The learning activities were progressed by various types of teaching and learning methods including 8 types of multiple intelligence teaching strategy. The lesson plans were developed according to the process of practical problem solving model. 6 periods of lesson plans and worksheets were developed. Second, the practical problem-based instruction using multiple intelligence teaching-learning strategy were evaluated to increase students' positive learning attitudes, motivation, and good eating habits.
