현재 우리의 7차 교육과정에서 교육의 보조 도구로써 교실에서 사용될 수 있는 것은 별로 많지 않다. 그래서 AvaLab은 이 시점에서 좋은 도구가 될 수 있다. AvaLab은 컴퓨터에 익숙하지 않은 학생을 위한 GUI 프로그래밍 도구이며, 현재의 교육 과정에서 필요로 하는 창의성을 키우기 위한 한 도구로써 교실에서 사용될 수 있다. 사용하려면, 먼저 학습자는 프로그래밍 아이디어를 생각하고, 아이콘 기반의 AvaLab을 통하여 프로그래밍한다. 프로그래밍 후에 학습자는 로봇의 결과를 생각하고 토론할 수 있다. 만약 그 결과가 정확화지 않다면, 로봇은 피드백을 보일 젓이다. 그러므로, AvaLab은 초보자를 위한 도구이며, 7차 교육과정에 적합한 도구이다. AvaLab의 특징 중 하나는 아이콘 기반의 흐름도 모델로 구성되어 있다는 것과 학습자는 입력과 출력 센스를 갖는 로봇을 이용해 실습할 수 있다는 것이다.

Evolutionary Computation is not only widely used in optimization and machine learning, but also being applied in creating novel structures and entities. This paper proposes evolutionary topic maps that can suggest new and creative knowledge not easily producible by humans. Interactive evolutionary computation method is applied into topic maps in order to accept human evaluation on feasibility of intermediate topic maps. Evolutionary topic maps are creativity support tools, helping users to encounter new and creative knowledge. Further work can greatly improve the system by providing more operations, preventing over-convergence, and overcoming user fatigue problem by providing more intuitive user interface, better visualization, and interpolation mechanisms.

Today`s education is in the 7th education curriculum. But, there is nothing that can be used in the classroom as a tool for education supplement. Easylab is a GUI-programing tool for students who not good at using computers. EasyLab is used in the classroom as a kind of tool to give a rise to ingenuity and creation which need at present education curriculum. When use it, first, learners think of programming-ideas, then program through icon-based software-EasyLab. After programing, the leaner can see the result directly thorough the programing code which are delivered by EasyRobot. So, leaner can study and discuss with the robot`s result. If, the result is incorrect, the robot will do a feedback as a kind of rule. One of the EasyLab`s specific property is that consisted icon-based flow-chart model. And leaner can practice with the robot that have input and output sense.

The purpose of this study is to examine overseas educational informatization infrastructure evaluation indicators and create data for establishing and developing educational informatization policy directions in the future. We analyzed the cases of OECD PISA, UNESCO, ITU, the German Wetelsmann Foundation, the U.S. Department of Education, and China as educational indicators. As a result of the analysis, evaluation items for electrical and telecommunication facilities such as the school's Internet connection network were commonly found in all indicators, and the ratio of learners to PCs (LCR) was also found in 3 out of 4 indicators. Through this study, it is expected that it will be of great help in conducting educational informatization evaluation suitable for the rapidly changing modern society and developing evaluation tools.

The purpose of this study is to define the teachers' perception for technology leadership when utilizing the Digital Textbook (DT). The subjects of this study were 97 elementary school teachers (40 males and 57 females) working in digital textbook research schools that implemented digital textbooks in 2009. Needs assessment instrument was revised based on previous instruments. Perception was calculated using Borich formula. According to the results, teachers of digital textbook research schools recognized 'teachers' instructional methods' as the most important area, while the least recognized area was 'support by the school'. The highest technology leadership needs by categories included 'role setting between members when implementing digital textbooks', 'instructional methods to cultivate creativity when using digital textbooks', 'troubleshooting digital textbook problems', 'additional staff support in case of problems', 'development of various assessment tools for measuring the effect of the digital textbook', and 'support of digital textbook resources for students with disabilities'. Based on these results, the study proposed specific methods to enhance technology leadership for the successful introduction of digital textbooks in schools.

The emergent information society requires the talent for creative thinking based on problem-solving skills and comprehensive thinking rather than simple memorization. Therefore, the Korean curriculum has also changed into the direction of the creative thinking through increasing short-answer questions that can determine the overall thinking of the students. However, their scoring results are a little bit inconsistency because scoring short-answer questions depends on the subjective scoring of human raters. In order to alleviate this point, an automated scoring system using a machine learning has been used as a scoring tool in overseas. Linguistically, Korean and English is totally different in the structure of the sentences. Thus, the automated scoring system used in English cannot be applied to Korean. In this paper, we introduce an automated scoring system for Korean short-answer questions using predictability and unanimity. We also verify the practicality of the automatic scoring system through the correlation coefficient between the results of the automated scoring system and those of human raters. In the experiment of this paper, the proposed system is evaluated for constructed-response items of Korean language, social studies, and science in the National Assessment of Educational Achievement. The analysis was used Pearson correlation coefficients and Kappa coefficient. Results of the experiment had showed a strong positive correlation with all the correlation coefficients at 0.7 or higher. Thus, the scoring results of the proposed scoring system are similar to those of human raters. Therefore, the automated scoring system should be found to be useful as a scoring tool.
