DEVELOPME pazjz/ NT OF A RELATIONAL DATABASE FOR LEARNING MANAGEMENT SYSTEMS
ABSTRACT
In today's world, Web-Based Distance Education Systems have a great importance. Web-based Distance Education Systems are usually known as Learning Management Systems (LMS). In this article, a database design, which was developed to create an educational institution as a Learning Management System, is described. In this sense, developed Learning Management System consists of basis of Virtual Education Institutions.
In this study, a fully relational database design has been realized in compliance with SCORM standards and got ready to be used as Virtual Education Institutions. This system can be used for any required education institute and it can be run within the same interface. In LMS that will be generated, a faculty or institute can be defined and academic and all administrative processes of the defined institute can be managed with the designed system. Proposed database design has been used in a LMS of Afyon Kocatepe University. In this system, many processes like indexing, uploading, downloading, production and editing of web based learning materials can also be performed easily and safely.
Keywords: Distance Education, E-learning, Web-Based Distance Learning Systems, SCORM, Relational Database Design.
INTRODUCTION
In today's modern age, changes are observed people's life style. Development of mobile communication systems and mobility of the people play the most important role about this issue. People's daily activity programs are divided into many different type activities. The main concern in education is that how classical education institutions will establish education environment of increasing active population. The purpose of mobile education is to move today's stable education environment to a virtual, flexible education environment of the future (Yuen and Wang, 2004).
Today, there is a growing interest in online learning all over the world (Elango, 2008). Electronic learning plays important role not only in academic institutions but also in small and medium-sized enterprises, which have the will to renew knowledge and experience of their staff. E-learning provides practical solutions to the students, who did not participate in the past education processes (Roy and Raymund, 2008). At this point, scientists have emphasized on customization, interaction and control (Piccoli, 2001). An e-learning program should be especially prepared for all students with the integration of different objects, past experiences and also these students should increase their own activities (Collins, 2005; Collins, 2006; Hodges, 2004). E-learning trusts in current information and communication technologies for distribution of learning contents.
Learning process or its ambiance is organized according to either synchronous or asynchronous method. E-learning, which has been developed as a learning solution, represents the distance education with the flexibility of educational software and process covering synthesis of different technologies (Yapicioglu, 2001).
Increasing internet using rate and developments in the infrastructure of today's internet have caused many improvements in web-based software and services. As a result of these improvements, education activities have begun to be performed by using the internet and network technology. Many technological tools like electronic books, electronic mails and conference environments have also taken active parts in these kinds of education activities. Due to increasing rate in using these tools and related education methods, a special education system has appeared. The whole education system is called as "Web-based Distance Education System" (WBDES).
Today, distance education systems are established in many universities and education-teaching activities are performed via these systems. One of the big reasons in increasing using rate of Web-based Distance Education is requirements to these kinds of systems in parallel with developments in the information technology.
One of the most important advantages of WBDES is being able to provide asynchronous education within a virtual education environment. In a WBDES, students can easily access to the educational contents, which was transferred by educators to the system and take advantage of these sources by using different educational tools.
Because of its advantages on costs, WBDES is also preferred to be used rather than other models or systems (Carswell and Venkatesh, 2002). Today, the most important reason in increasing the number of WBDES and to be accepted by students is their independent working mechanism from time and location (Bullen, 2006).
