E-Learning is different from the traditional classroom learning and examinees can take a class individually anywhere by online. And it is difficult to proctor an examination because they also take a test by online. However the results of the online test are included in their examination scores. Therefore, it is very important to authenticate the examinees. In this paper, we propose improvement of fairness system for online test using camera. Students can take a picture after every online classes and it has been saved. And during the test, ELTS(e-Learning Test System) takes images, detects the faces, and protects from getting another person to sit for cheating. After examination, the images have been transferred with the answer sheets to the cyber school management system. And a report card will be printed out with the user's images. Moreover, it will authenticate oneself and protect the online test from cheating.

The purpose of this study is to analyze the environmental characteristics of Hansung Girls' Middle & High School located on the northern slope of Mt. Naksan in Seoul but sited at different aspects. The measured temperature and illumination in March, July and December were analysed. The proportion of window size and questionaries were used also. The results of observation are as follows: (1) The temperature of the southward classrooms was $3.6^{\circ}C$ higher than eastward or westward classrooms in March, but the difference of the both values in July were only $0.3^{\circ}C$ in the average. (2) The temperatures in December decreased in the order of aspects: southward, westward and eastward. (3) The highest values for illumination appeared in the classroom faced to the south and the values decreased from westward to eastward. (4) Temperatures and illumination were varied not only with the aspect but also with the number of story and the proportion of the window size. However, the heating facilities and illuminators are installed evenly without considering the condition of the buildings. The heating facilities should be installed differently according to the direction and height of the story of the building. The heating facilities should be installed sparsely for the classrooms faced southward, and more densely near the hallway side to achieve satisfaction of students and to save expenses of heating. It will be better that electric power switches for window side have to be set separately from hallway side. Improvement of the condition of illumination and temperatures will help students to promote their health and learning.

This study was conducted to contribute to the basic data for decisions on environment policy improvement in health promotion for students in elementary, middle and high schools. This study was carried out to investigate the extent of indoor air pollution in elementary, middle and high schools in residential, traffic congestional and industrial areas. The concentrations of major indoor air pollutants(carbon monoxide, carbon dioxide, respiratory particulate, radon) and thermocircumstance (temperature, relative humidity, intensity of illumination) indices were observed from June to August 2000. As results of the survey, the mean values of thermocircumstance in school were $26.94{\pm}1.15^{\circ}C$ of temperature, $68.88{\pm}5.31%$ of humidity and $268.26{\pm}164.60$ Lux of intensity of illumination. The mean concentrations of carbon monoxide, carbon dioxide, respiratory particulate were $8.36{\pm}0.29\;ppm$, $547.66{\pm}175.58\;ppm$, $36.23{\pm}48.39\;{\mu}g/m3$, respectively. These values were lower than those of the indoor environmental standard on the first clause of Article 45 of public utilization service notified public hygiene of the Ministry of Health and Social Affairs. The mean concentration of radon was $20.07{\pm}17.95\;Bq/m3$. Which was below the U.S. EPA radon action level.

In this paper, We evaluated students' computational thinking in elementary school for SW education. Also, we analyzed on the difference of students' computational thinking according to the level of school's educational information. As a result, We confirmed that students' computational thinking were deferent according to the experience of schoolmaster's SW education and the ICT infra of school. In particular, students' computational thinking were meaningfully deferent according to the SW education experience of schoolmaster, the number of mobile devices for education and the speed of school network. Accordingly, we proposed the policy to heighten the effect of SW education. The policy were the extension of SW education for teacher, school network infra and mobile device for education.

Ubiquitous computing and mobile technologies provide much scope for designing innovative learning experiences that can take place in a variety of indoor and outdoor settings, such as botanical gardens, parks, museums and classrooms. In this paper, we present our own innovative work for bridging indoor and outdoor field-trip learning activities with the support of RFID with reader device on ubiquitous environments. The function of our system is based on strategically located RFID tags placed on objects around settings which are identified using the mobile device installed to an RFID reader. The mobile device reads the RFID tag and sends the learner's request to the field-trip learning system. And learners can be learning activities according to theirs learning levels. We also focus on the use of intelligent agents to customize learning contents for individual learners. The result of our experiment indicates that learner enjoyed learning where mobile devices are used in the system, supporting the learning activities in the context of which they are taking place.

Indoor air quality has been addressed as an important atmospheric environmental issue and has caught attention of the public in recent years in Korea. Good indoor air quality in classrooms favour student's learning ability, teacher and staff's productivity according to other studies. In this study, each classroom at four different schools was chosen for comparison of indoor and outdoor air quality by means of source generation types such as new constructed classroom, using of cleaning agents and purchased furniture. Temperature, relative humidity (RH), carbon dioxide $(CO_2)$, formaldehyde (HCHO), total volatile organic compounds (TVOCs) and particulate matter with diameter less than $10{\mu}m\;(PM_{10})$ were monitored at indoor and outdoor locations during lesson. HCHO was found to be the worst among parameters measured in new constructed classroom, HCHO and TVOCs was worst in classroom with new purchased furniture, and TVOCs was worst in classroom cleaned by cleaning agents, Indoor $(CO_2)$ concentrations often exceeded 1500 ppm indicating importance of ventilation. Active activity of students during break time made the $PM_{10}$ concentration higher than a lesson, Improvements and further researches should be carried out considering indoor air quality at schools is of special concern since children and students are susceptible to poor air quality.

Generally, teaching in computer Labs is more difficult than teaching in a normal class for teachers to give students systematic learning. One of the reasons is that the students who participate in the class tend to use the programs that are not related to the practice included in the curriculum. Therefore, the students cannot focus on the subjects that they should do. To solve this problem, there are many kinds of systems that can control the students' computers. However, they cannot help teachers to manage the students and computers due to the inconvenience of usage and the lack of functions. In this study, we analyzed the problems in the computer-practice classwork and designed a new system to support that the students can participate in the computer classes with more attention. In addition, it is offered that the computer teachers can manage the classes and the students more efficiently with this new system. For these purposes, the effects mentioned were approved before in the real lab situations. Experimental results showed that the proposed system can improve the rate of the students attention, leading them to get better grades on the achievement test.

Given that the culture of the mathematics classroom has been perceived as an important topic in mathematics education research, this paper deals with the construct of sociomathematical norms which can be used as an analytical tool in understanding classroom mathematical culture. This paper first reviews the theoretical foundations of the construct such as symbolic interactionism and ethnomethodology, and describes the actual classroom contexts in which social and sociomathematical norms were originally identified. This paper then provides a critical analysis of the previous studies with regard to sociomathematical norms. Whereas such studies analyze how sociomathematical norms become constituted and stabilized in the specific classroom contexts, they tend to briefly document sociomathematical norms mainly as a precursor to the detailed analysis of classroom mathematical practice. This paper reveals that the trend stems from the following two facts. First, the construct of sociomathematical norms evolved out of a classroom teaching experiment in which Cobb and his colleagues attempted to account for students' conceptual loaming as it occurred in the social context of an inquiry mathematics classroom. Second, the researchers' main role was to design instructional devices and sequences of specific mathematical content and to support the classroom teacher to foster students' mathematical learning using those sequences Given the limitations in terms of the utility of sociomathematical norms, this paper suggests the possibility of positioning the sociomathematical norms construct as more centrally reflecting the quality of students' mathematical engagement in collective classroom processes and predicting their conceptual teaming opportunities. This notion reflects the fact that the construct of sociomathematical norms is intended to capture the essence of the mathematical microculture established in a classroom community rather than its general social structure. The notion also allows us to see a teacher as promoting sociomathematical norms to the extent that she or he attends to concordance between the social processes of the classroom, and the characteristically mathematical ways of engaging. In this way, the construct of sociomathematical norms include, but in no ways needs to be limited to, teacher's mediation of mathematics discussions.

Recently, as more web-based applications are widely used, various methods for education are developed in practical areas. As a result, in many organizations, virtual educations such as WBI learning. CAI, and distance learning are offered actively. With the advantages of web-based education, in order to achieve feasible and efficient effects on education. a new web-based instruction model that considers the abilities, the interests, and the aptitudes of students individually is required. In this paper, a new web-based instruction model, called a hybrid model, is proposed and implemented. And then, two model - the stepwise model and the hybrid model- are applied to a computer accounting class of a vocational high school. Students attend the web-based class in a computer center for 100 minutes autonomously. After the classes, a questionnaire is made in order to analyze both the effect on that class and the learning fulfillment of the proposed instruction model.
