Blended learning is a teaching method utilizing all the advantages in 'on and off-line' learning circumstances in order to enhance the learning effect and efficiency, more than the simple use of online factors in the classroom education. In this paper, we present the realization and simulation of algorithm for the realtime evaluation of low-grade and high-grade subjects in order to implement smart e-learning system, considering a lecture intelligibility. In order to grasp the levels of student's intelligibility, we simulated a function that automatically summarizes the study contents of class given by a lecturer. Especially, in administrator mode of smart e-learning system, we suggested and simulated a system in order to help the lecturer to easily manage the student's grades, and we have provided software to tell the student's intelligibility of lecture, analyzed the rate of incorrect answers, automatic judgment of lecture intelligibility and judge the weakest subject.

Minute papers are brief papers written at the end of a lecture in response to one or two questions posed by the instructor. The answers are discussed briefly at the beginning of the next lecture. We used minute papers to follow students' understanding and response to lecture demonstrations in an introductory general chemistry course. An analysis of these minute papers suggest that the following characteristics are important, when using demonstrations as teaching aids. 1) The purpose of a demonstration should be stated as explicitly as possible. 2) Instructors should be explicit about what is happening and what students should be looking for. 3) Demonstrations should be kept as simple as possible, perhaps illustrating one concept. Finally, we note that students believe that the visual component of demonstrations enhances their comprehension of chemistry concepts.

Lecture Evaluation system is an only way, so far, to evaluate the quality of lectures in our university and yet has several problems. This system does not have any effects on professors; however, it is rather used to threaten assistant professors and/or part-time/full-time lecturers. As a result, students are still dissatisfied with the unchanging lectures of professors. Generally speaking, We should consider new ideas to introduce a head teacher system or improve the lecture evaluation system to open doors wider for teachers, professors do their best to expand students' understanding by practicing the Lecture Evaluation System. In fact, it is hard to keep the objectiveness that the professors estimate the quality of professors. That is why this check list should be restricted only as a guideline among the system. After all, it is expected to bring better educational circumstances when the system functions properly to provide professors to research more.

Efforts were made to improve the efficiency of college education through the use of information technology. This paper investigates student perceptions of a lecture club provided on a social networking website. For the empirical study, the instructor ran a lecture club for two consecutive semesters on Cyworld (www.cyworld.co.kr), a popular website among Korean youth. The research subjects were students enrolled in a Popular Culture & Fashion class. A questionnaire was distributed on the last day of the lectures. After excluding students with perfunctory responses and those who did not sign up for the community website, a total number of 297 questionnaires were used for analysis. Descriptive statistics, Pearson correlation analysis, one-way ANOVA analysis, Duncan test, and t-test were carried out, with the SPSS for Windows 12.0 being used for statistical analysis. The findings show that most students subscribed to the website and responded with a favorable attitude that the lecture club was helpful.

The purpose of the research on the noise of educational facilities is to build up pleasant environments by minimizing the influence on the students in the school. This study provides fundamental data for acoustic design by measuring, computer simulation and analyzing the room acoustic characteristics of the lecture room in middle school. For measurement on the factors of room acoustic, RT of lecture room and noise reductions depending on various walls of different structures were measured and analyzed. The lecture system being installed and carried out on the normal lecture room was divided into 4 types-employment of multimedia machines, employment of multimedia machines and loud speakers, employment of loud speaker, and existing verbal speaking-and SPL for each type was measured and analyzed. Based on the measured characteristics of acoustic characteristics for normal lecture room, the problems for environment of noise were understood through computer simulation, applications for improvements of performance for each facility were studied, schemes for improvements of performance by using the effects were presented, necessary fundamental data were secured, and schemes to enhance flexibility on the existing facilities of school against changing educational courses were secured.

"e-Leaning" system is classified by lecture time into two types, that is, "synchronous type" spent the same lecture time between the lecturer and students, and "asynchronous type" spent the different lecture time. The size of image database is huge, and there are some problem on the management of the lecture image database in "asynchronous type" e-Learning system. The one of them is that the time tag for the database management must be added manually at present, and the cost of the addition of the time tag causes a serious problem. To resolve the problem, we will use the character recognition for the characters written by the lecturer on whiteboard, and will add the recognized character as a keyword to the tag of the image database. If the database would have the keyword, we could retrieve the database by the keyword efficiently, and the student could select the interested lecture scene only in the full lecture database.

This study aims to apply World Wide Web(WWW) image files to visual material in lectures. Especially handles "Aesthetics of Landscape Architecture." Visual Materials of 800 web sites were searched and analyzed. It is found that web search needs a subject oriented web guide. It says now a need of application web material to lectures. Matching the web images with the subjects of lecture, above all, is the main approach of this study. Thus, a list up method is supposed, series of web image data to be inclusive in two tables. The data distribute on sub-subject, and applicant as materials in picturing objects of slide show, web guide, and single image. Two cases of lecture subjects were chosen in this study. A case that needs various visual materials and other case of advanced materials that needs a special web guide. Chance of results of this study is not yet fully clear in real lecture. It is sure, as an article of cyber lecture that provided result of increasingly participant's interest. By this study, it will be possible a fully made lecture material by further study.her study.

본고에서는 수학사의 교수학적 의미를 살펴보고, 초등학교 6학년 학생에게 적합한 수학사 특강 자료 3차시(120분) 분량을 개발하여, 이를 수학자가 직접 학생들에게 강의함으로써 수학사 내용 및 수학자로 인해 학생들의 수학에 대한 태도에 어떤 변화가 일어나는지를 조사해 보았다. 그 결과 수학사 내용뿐만 아니라 수학자와의 만남도 학생들의 수학에 대한 태도 형성에 긍정적 효과를 주는 것으로 나타났다.

This study was performed to know about the conformity tendencies of adolescent and adult groups based on lectures of the expert on the topic 'the cicada'. Characters of each lecture were 'he pure natural science', 'positiveness', 'negativeness' and 'neutrality,' and then attitude changes on the cicadas were investigated with a questionnaire. Consequently, half of the adolescent and adult groups thought of the cicadas' sounds as 'noise' through mass communications respectively. They had a neutral attitude, neither positive nor negative, on cicadas' sounds in the beginning. Attitudes of the people on the cicada, however, were changed positively only with a pure natural science lecture. In this case, the adolescent group was more prevalented by the lecture than the adult group. In other words, the positive-based lecture affected them positively, while the negative-based lecture affected them negatively. The conformity tendencies of adolescent groups participating in the positive-based lecture were substantial. In conclusion, as we can see from the so-called Kohlberg's 'stages of moral development', conformity tendencies of attitudes towards cicadas' sounds were generally much more prevalent in the adolescent group, compared with the adult group, even though there are some differences in subcategories.
