Designing Application of M-Learning based on Content Management System

Abstract: Innovation in the telecommunications technology develops fast and aligned with the development of modern society characteristic that have high mobility, flexible, easy and satisfying search service, and the pursuit of efficiency in all aspects. Currently, the use of mobile device like mobile phone, pocket PC and PDA (Personal Digital Assistant) has become a common sight in everyday life. Commonly used mobile devices, most are able to perform data communication via the Internet. This development makes people able to develop a method of learning that is based on wireless and mobile technology, called mobile learning (m-learning). Mlearning has its own characteristic because of the limitations of mobile device. Merging mobile web technology with Content Management System can become alternatives in developing m-learning applications. Designing m-learning based on content management system aims to simplify the management of content. M-learning generated in the form of mobile web that accessed by users through mobile phone. The m-learning is expected to be one of the alternatives in the delivery of study materials to students.

Content Management System

Abstract: The growth in web technologies and the need for improved and more secured role based web management has spurred the growth for content management systems. A content management system, as the name implies, is managing web content and, look and feel via role based access for viewing content, editing content and administering the portal dynamically. This role based security permits organizations to create a hierarchical multi-tier architecture model for securely managing individual pages or even individual modules on a page. The basic idea behind a portal is to provide an easy interface to users while maintaining the flexibility for developers to plug-in new features. It is a tool that allows people to communicate interactively and effectively by sharing documents, images and latest developments almost instantly. It provides a framework that works on top of role-based security. This can be adapted to develop any site that requires content management. Hence, it caters to the needs of a wide range of audience. While portals look like any other static web site with tabs to navigate between pages and page content organized in a neat readable format, they provide a dynamic way to modify, maintain and monitor usage. The basic architecture of the portal consists of tabs and modules. A collection of modules on a page constitutes the contents of the tab and a collection of tabs make the entire portal. We will look individually into each element that constitutes the portal. Tabs in the portal constitute the basic navigation bar. From a user's point of view this is the basic container of all data and hence its accessibility is of at most importance. Controlling the visibility of the tabs via a role-based mechanism allows managing users belonging to a wide spectrum. Users with different roles only see the tabs that they are authorized to view. Thus, the portal can be set up in such a way that two users with different roles see completely different web contents. Portal administrators manage tabs and they can dynamically create new tabs and add new modules onto the tab. Modules act as the container of all data and content. Modules in a tab can be either in the right pane or left pane depending on where the content is to be displayed. This way we use the entire space on the computer screen. Like view permissions on tabs, role based security can also be used to …

Virtual Laboratory Implementation To Support High School Learning

Abstract: Learning activities are not limited to the delivery of theory content and evaluation, but they also include some experiment activity in laboratory. Some subjects require experiments activity in the laboratory, i.e. Biology, Mathematics, Chemistry and Physics. Those subjects demand the educational institution, high school in this occasion, to provide facilities and infrastructure in the form of laboratory equipment in order to support experiment activities. However, the experiment activity currently conducted in laboratory not yet suffice the need of student to learn independently. An additional experiment activity is needed, in such way that takes time other than learning hour and can be done independently. Laboratory access must not limited to attending school laboratory physically, in a sense that nonphysical laboratory such as virtual laboratory may also be included. This research result an implementation of virtual laboratory in the form of computer application that is available anybody for experiments with affordable cost at any given time and place as long as connected to main server provider.

Implementing Code Igniter Framework in Open Source Mobile Learning Application

Abstract: The concept of learning at any time and any place is unable to get fully implemented yet. The reason is that the currently available e-learning system requires a personal computer to access it. Moreover, users need to find convenient place to access the e-learning. In order to implement the concept, an applications of electronic distance learning that run on mobile device, such as cell phone, personnel digital assistant (PDA), or smart phone, is needed. The application is called mobile learning (m-learning). A different approach to design m-learning application is required due to the differences in mobile device and personal computer nature. This study implements Code Igniter (CI) framework that support model-view-controller (MVC) programming technique in order to decrease application development time. It may happen since Code Igniter provides a set of libraries that provides basic functionality to solve common problems. Using Code Igniter, developers no longer need to develop application from scratch and may directly focus on the codes that build m-learning application functionality.
