Preparing the 4th industrial revolution age, a diagnostic assessment management system which can collect nationwide data has been implemented and utilized for the development of the evidence-based educational policy. This study aims to develop heuristics to help to improve usability of such systems, which are utilized by primary and middle school community including teachers and students in the nationwide. To achieve the objective, previous studies related to the development of heuristics in the educational contexts as well as basic heuristics from Nielsen were reviewed, and usability problems of the web-based diagnostic-supplement system being currently utilized, as a sample system, were analyzed. Then, the first version of heuristics was developed. The developed heuristics were validated and revised through 2 rounds of the delphi methods with 15 experts. This study has an implication with preparing foundations on improving usability of such diagnostic assessment management system utilized by school community at the nationwide in educational contexts.

웹 사용의 보편화에 따라 많은 서비스가 이루어지고 있다. 이러한 서비스 중에는 웹을 통한 학습교육서비스 또한 많이 있다 웹 교육은 시간과 학습자의 수에 제약을 받지 않는 장점이 있으나, 웹에서 인증을 통해 학습 서비스를 받는 과정에서 로그 아웃이나 세션 시간 종료까지 실질적으로 사용자가 학습을 하고 있는지 활동을 자세히 알 수가 없어, 본 논문은 기반 Ormapper와 Java 세션 관리를 이용해서 학습을 받고 있는 사용자들을 관리하는 시스템을 개발하였다.

The Ministry of Education has serviced nationwide the diagnosis-supplement system for basic academic skills for elementary and middle schools since 2013. The purpose of this paper is to propose an improvement plans of the diagnosis-supplement system by analysing system utilization status, 2015 and requirements of teachers and experts. For this study, over three times the taking rates and achievement rates were analyzed and the interviews and consultations of teachers and professionals were also analyzed. In conclusion, we proposed the improvement plans of the diagnosis-supplement system for the each of teachers and students.

The purpose of this study is to understand students' use intentions of Web Based Collaborative Learning (WBCL) system. To meet this purpose, we developed a research model based on the Decomposed TPB. This model contains 5 influencing factors: Explicit social influence(EXSI) and Implicit social influence(IMSI), Perceived Usefulness (PU), Perceived easy of use(PEOU), Perceived Playfulness(PP). Data was collected 254 university students from two different institutions. Also, the analysis is conducted to do the hypothesis testing by using PLS 3.0. The result shows that influence factors except PEOU have a important and significant impact on user Behavior Intention(BI). Using WBCL system and learning tool, team leader(that is referent) and members can be a good interaction. For these same reasons, We found that especialy Explicit social influence(EXSI) and Implicit social influence(IMSI) are special influence factors in reference group.

Due to significant advances in Internet technology, there have been many e-learning courses offered by universities and academic institutes nowadays through the Internet. And these courses have benefited many students who might be constrained by distance and time. Nevertheless, most web-based courses are lecturing courses that cannot fulfill the needs for engineering technology education. In this paper, we propose the design and implementation of web-based programmable logic controller(PLC) laboratory to support learning and training for industrial automation. The proposed web-based PLC laboratory system consists of virtual labs and remote labs. This web-based PLC laboratory can be accessed by registered students to practice PLC experiments at their own home, enhancing the quality of education without much increasing in the overall cost. With the help of web cameras, the students can even have experience the live PLC experiments through the Internet.

Recently. The web-based distance education system becomes generalized so that learners can study without being under the control of time and space. This shows that it is more widely used through Internet in education field. But the previous developed methodology for distance-lecture system has some problems, on the Distance Education. It takes much time and cost. In this paper, the need of the Distance-lecture system to apply component-based developing methodology is suggested to overcome these problems. Also, you can save lots of time and cost because it has the reuse, the convenient availability, and the transplantation of distance-educaton system through component-based developing methodology.

In recent creativity becomes a new request in the knowledge and information age. Robot programming education is an effective teaching method for improvement of creativity. Existing robot programming tools includes text-based or GUI-based development environment. Most of programming tools provide a simple tutorial system without interactive activity for beginners. In this paper, we propose an online robot programming education system based on web2.0, which embedded collaborative code creating tool, interactive tutorial chat and video conference tool to support collaborative code creating via web 2.0. Knowledge sharing tool allows users to share their collaborative source code. Besides, it makes users gained the experience and knowledge of program designing efficiently.

Most questions made for remote examinations on web-based education system use methods of making questions using fixed questions or randomly using item pools or automatically using degree of difficulty. Particularly, automatically selection methods using degree of difficulty is the kernel of a question that objectivity of the first degree of difficulty for questions and an effective questions selection using degree of difficulty and mediateness degree of difficulty based result of examination. This paper is use automatically selection methods for examination on web-based education system. Firstly, we present new question selection algorithms as regards degree of difficulty and distribution between all units. Secondly, we present new algorithms of mediateness degree of difficulty as regards education ability of students for adjust the degree of difficulty. We identified this algorithms is more effective as compared with previously algorithms on web-based education system.
