Development of an e-learning system for teaching machining technology

The manufacturing technique covers: turning, milling, drilling, holing etc. Much time and cost are used to teach these techniques. Particularly, computerized machines are continuously increasing in use. The development of educating engineers on computerized machines becomes much more difficult than with traditional machines. This is because of the limitation of the extremely expensive cost of teaching. The quality and quantity of teaching cannot always be promoted in this respect. The traditional teaching methods can not respond well to the needs of the future. Therefore, this research aims to the following topics; (1). Propose the teaching strategies for the students to learning machining processing planning through Web-based learning system. (2). Establish on-line teaching material for the computer-aided manufacturing courses including CNC coding method, CNC simulation. (3). Develop the virtual machining laboratory to bring the machining practical training to Web-based learning system. (4). Integrate multi-media and virtual laboratory in the developed e-learning web-based system to enhance the effectiveness of machining education through Web-based system.

User Acceptance Towards Web-based Learning Systems: Investigating the Role of Social, Organizational and Individual Factors in European Higher Education

As Internet use has proliferated, Web-based learning systems have become more and more popular. Numerous researchers have spent a great deal of effort to facilitate the promotion of high quality Web-based learning environments, such as intelligent Web-based learning systems and adaptive learning. To facilitate such researches, students' behavioral patterns must be observed and experimentally analyzed. However, building a Web-based learning system and the requisite collecting of behavioral patterns usually takes a great deal of time and effort. To solve this problem, this paper proposes a learning behavioral model based on Colored Petri Nets (CPN) to model and generate students' behavioral patterns. To verify the viability of the proposed model, this paper compares actual data collected from elementary school students with the behavioral pattern generated by the proposed model. The results prove: (1) The generated behavioral pattern approaches actual student behavior; (2) The generated behavioral pattern serves as adequate test data to test whether the predicted learning content of an intelligent e-learning system is appropriate; and (3) The proposed model is capable of recommending the appropriate learning content for students utilizing e-learning systems.

Web-based autonomous language learning system enjoys great popularity among college English learners in China. It provides abundant educational resources for the learner. Efficient use of available materials on the system needs intelligent resources recommendation and personalized guidance in learning strategies. This paper uses the data mining technology to build an automatic recommendation agent to enhance the function of web-based autonomous language learning system. The automatic recommendation agent serves two functions. One is to push related resources to the learner based on the results from association rule mining of all users' resource navigation patterns. The other is to provide immediate and individualized guidance for the learner concerning strategies of online language learning. The knowledge of personalized guidance comes from the machine learning of strategies adopted by students with varied level of achievements in language learning. The framework and data structure of its implementation have been presented in this paper. Experiments show that the automatic recommendation agent improves the management of educational resources on web-based autonomous language learning system and better facilitate students' language learning.

Factors affecting the intention to use a web-based learning system among blue-collar workers in the automotive industry

Resumo: Web-based Learning Management Systems are welcomed to support the teaching and learning process. Such systems can help learners to create their own schedules for studying, since the content to be learnt is available in the system for a period of time diverse from a class, within a school, in a specific schedule. However, whenever the learning process is mediated by a web-based learning system, the delay on providing feedback may cause student's disappointment or course abandonment. In this paper, we present a Web-based Learning Management System with Automatic Assessment Resources and some of its functionalities. The system is presented as a tool for supporting the diversity of learning rhythms that tutors face during the teaching and learning process of any subject. In addition, a report is described based on experiences that authors have been had during the last three years.

The advancement of information technology drives transformation in education, including at SMK Fadilatul Ilmi Serang City. However, the learning process at this school remains conventional with limited digital media usage, necessitating a web-based e-learning system to enhance flexibility and efficiency. This study aims to design and develop a web-based e-learning information system to support distance learning, material management, assignments, automated exams, and assessments. The research method employs a qualitative descriptive approach and software engineering with the Waterfall model. Data collection was conducted through interviews, observation, literature studies, and documentation. The system was developed using PHP programming language, MySQL database, and HTML/CSS for the interface. The result is an e-learning system with three user levels (admin, teacher, student), featuring account management, learning materials, online exams, instant grading, and score reports. Implementation at SMK Fadilatul Ilmi demonstrated increased efficiency in teaching-learning processes, accessibility of materials beyond spatial/temporal constraints, and ease in evaluating learning outcomes. This system is expected to be a sustainable solution for digitizing vocational education.

The rapid growth of Information and Communication Technologies (ICT)—specifically, the Internet—has given emergence to e-learning. Resultantly, web-based e-learning systems are being increasingly developed to enhance the learning process. However, the utilization of such systems is low, mainly owing to poor quality content and overall design problems. To improve usage, it is imperative to identify the factors with the most significant impact on the quality of these systems so that the e-learning industry keeps these factors in consideration while developing e-learning systems. This study focused on the identification and prioritization of factors related to the design quality of e-learning systems through a hierarchical quality model. Thus, firstly, an extensive literature review was conducted to identify the factors that most affect the quality of web-based e-learning systems. Secondly, among the identified factors, only those with the most significant effect were considered. To identify the most important quality criteria, a survey was conducted. An instrument was deployed among 157 subjects, including e-learning designers, developers, students, teachers, and educational administrators. Finally, a second instrument was distributed among 51 participants to make a pairwise comparison among the criteria and rank them according to their relative importance. The identified and prioritized factors were classified into four main categories. Among these four factors, content was identified as the most important factor, whereas design was found to be the least important factor.

Owing to the lack of face-to-face interactions, students using a web-based learning system are likely to study alone and with relatively little classmate support and pressure. Teachers in a web-based learning system may apply the group-learning model to overcome this problem. Therefore, teachers first need to organize, manage, and monitor the group learning. Additionally, they must take appropriate actions based on teaching strategies to improve the learning achievements of the students. To perform these tasks effectively, the teachers must obtain relevant information by searching and analyzing the huge amount of web-access logs or by monitoring web interactions. This will be burdensome and difficult to do well for the teachers. This work presents novel methodologies for developing instruments to assist teachers in performing grouping, intervention and strategy analysis. The proposed methodologies apply data mining tools provided by existing database management systems. A tool is initially R developed to assist in organizing learning groups according to teacher specifications. Database techniques, including multidimensional cube, are then applied to make student web logs meaningful and helpful to teachers in managing group learning. The associate rule mining tool is finally employed to assist teachers in analyzing their pedagogical strategies. These tools relieve the teacher of tedious data collection and analysis, and thus can focus on managing the groups to promote student learning achievement.

Recent advances in network technology are an important form of IT-enabled learning and learning support for on line education. More and more learners obtain knowledge via the Web-learning Instruction (WBI). At present, most of the studies in the on line education are focus on the technological aspect (e.g. Personalizational technology development), while, how to design and arrange the content of learning material is neglected. Therefore, students usually induce the problem of disorientation and cognitive overload when they use Web-based learning system. It is beneficial to provide and design proper style to present learning material to help students learn with the Web-based learning system (WBLS). This study adopts a graphic organizer technology - concept maps to design the learning materials into Web-based instruction (WBI). This study also conducts a satisfaction survey to understand students' perception and attitude toward this type of content representation style. Results indicate that students have positive perception and attitude of the concept mapping content representation style.

Practice and engineering ability training is very important for university students who major in computer science and technology. We proposed a practice and engineering training mechanism for computer major students. Firstly, the teaching mode which emphasizes both theory and practice for the professional foundation curriculum system was reformed. The programming, data structure, discrete mathematics and object-oriented programming are taught in the laboratory and evaluated through our online judging system. Secondly, the training subjects of core curriculum system were well designed and an engineering practice ability training mechanism based on enterprise training and open laboratories training was also presented. To cultivate the engineering practice ability, the open lab in university provides lots of projects for students and the cooperative enterprise also gives enough chances in their senior year. At last, a professional competence-driven innovation ability training mechanism was introduced. To further excite the innovation ability and practical ability, we choose some excellent students to participate in subject competitions, such as ACM International College Student Programming Competition (ACM-ICPC) and Chinese College Student Programming Competition (CCPC) and so on.

A new remote laboratory system for learning hardware design and experiment of digital circuit has been developed. It employs shared resources and an e-learning system based on the top-down method specializing in the logic circuit design and featuring a quick acquisition of the hardware-description-language-based design skill. The wide use of the Internet motivated us to develop seamless remote and actual hardware laboratories for hardware design laboratory course, and for students to learn the digital circuit design by themselves. The proposed remote laboratory utilizes actual hardware and actual measurement tools in a time-sharing fashion. The combinatorial use of FPGA/PC connected test hardware and PC-based measurement equipments has made it possible to develop a remote multi-user and time-sharing hardware experiment system. As all students are equipped with high-performance Laptop PCs, CPU intensive development tasks can be performed by each student's client PC in a rich-client environment. The prototype the remote-laboratory and self e-learning system are under-construction, and will be used for the third grade CS students from year 2005

With the rapid growth of the Internet and the increasing popularity of the World Wide Web, web-based learning systems have become more and more popular. However, in general Web-based learning systems, learners may often get lost in the enormous educational materials (Eirinaki & Vazirgiannis, 2003; Murray, 2002). This kind of situation refers to a disorientation problem. In addition to the disorientation problem, general Web-based learning systems provide every learner with uniform course content and presentation without considering the different knowledge level of learners. Therefore, the course content may be insufficient or unnecessary for learners with different knowledge level. This kind of situation was referred to as cognitive-overhead problem by Murray (2002).
