Implementing MOODLE as a Platform in Distance Learning as Learning Management System (LMS)

Implementing MOODLE as a Platform in Distance Learning as Learning Management System (LMS)

INTRODUCTION

E-learning and distance learning are forms of learning that take place outside of a traditional learning environment.  Learner who are not able to be present in a traditional setting for various reasons and  have access to computers and Internet (Liao & Lu, 2008) have the ability to learn at their own time and in their own space with different means of interaction (Quan-Haase, 2005).  Distance learning has become an important part in the education sector by opening the opportunities for a wider audience to have a degree or finish their study (Kaya, 2012; Liu, 2013; Secreto, 2013).   In an environment of e-learning class, students can interact and benefit from the technologies such as online references, project teams, video-conferencing, chat room and discussion board, personalized coaching (Bogdanov, Ullrich, & Isaksson, 2012; Dubas & Hill, 2013; Liao & Lu, 2008). In e-learning, social software is used to support the constructivist approach to create a cooperative approach to learning and construct a more cohesive learning community (Waycott, Sheard, Thompson, & Clerehan, 2013).  With the widespread of E-learning and distance learning, institution needs software to facilitate learning and course management. Therefore, there are companies and developer that design and market Learning Management System (LMS) to educational institutions (Lawler, 2011).
Learning Management System (LMS) support formal and distance education in education institutions around the world (Bogdanov et al., 2012; Dooga, 2010; Fernandez, Insfran, & Abrahão, 2011; Kaya, 2012; Liu, 2013; Ravanelli & Serina, 2014).  LMS offer an electronic platform to upload learning and study materials like presentation and text, student assessment, organize student activities (Lawler, 2011).  Learning Management System (LMS) software adoption rate went above 95% in the education sector (Thoms & Eryilmaz, 2014).  These systems are also referred to as Course Management Systems (CMS) and Virtual Learning Environments (VLE) (Lawler, 2011).  Most of the higher education institutions are using (LMS) to manage its needs of learning and teaching processes (Kaya, 2012; Richardson, Daniel, Sales, & Flora, 2012; Vallejo, 2011).  Moreover, institutes who offer e-learning or distance learning have adopted LMS, commercial or open source systems, because it have a significant role to play.  LMS plays an important role to supports high quality educational practices, especially in e-learning and online lessons environment.  With Moodle, e-learning can enhance learning achievement especially by using collaborative learning with the problem-based learning (Davoli, Monari, & Severinson Eklundh, 2008; Tiantong & Teemuangsai, 2013).
Moodle stands for Modular Object-Oriented Dynamic Learning Environment.  It developed in 2001-2003.  Moodle is an open-source platform that is licensed under the General Public License, which makes it widely used because of its highly cost effective. One of Moodle forum is a Learning Management System (LMS) specifically designed to educational institutions to support teaching and learning.  When it comes to choosing between open source platforms, Moodle comes to lead because it meet the users’ needs easily (Kaya, 2012; Liu, 2013; Matei & Vrabie, 2013; Ravanelli & Serina, 2014).  According to a recent statistics of Moodle users, there are approximately 85,390 active Moodle sites that were registered from 240 countries that over 8,278,974 courses with 77,090,101 users around the world. Therefore, it is always supported by development communities (Moodle.org). Studies prove that Moodle enhanced students' understanding and learning achievement successfully (Hassan, Hassan, Omar, Zakaria, & Nor, 2012; Jalobeanu, Naaji, Dumbraveanu, & Herman, 2011; Lai & Sanusi, 2013; Liu, 2013; Thoms & Eryilmaz, 2014).   Computer programming students found that Moodle was truly applicable to develop and organize the collaborative learning activities.  Socio-constructivist pedagogy is an important approach for e-learning which is supported by Moodle (Brandl, 2005; 2008; Elias, 2010; Lai & Sanusi, 2013; Mihailescu, 2009; Paier, 2007; Ravanelli & Serina, 2014; Vallejo, 2011).  Furthermore, users as lectures and students considered social influence and facilitating condition among the factors influenced them to use Moodle (Liu, 2013; Thoms & Eryilmaz, 2014).  Additionally, students actually enjoyed working through the Moodle as a team, using the computer network successfully to create a collaborative lesson with problem-based learning (Davoli et al., 2008; Tiantong & Teemuangsai, 2013).
International Islamic University Malaysia (IIUM) used Moodle as a platform in (iTa'leem) which stands for (Interactive Teaching and Learning Environment System).  IIUM is in the implementation stage in the process of the migration from LMS to iTa'leem which is a customized and enhanced of the open source Moodle.   It was developed by a developer from Moodle and a team from IIUM to facilitate an easy interaction between teachers and students. Furthermore, iTa'leem offer many services for the lectures online such as uploading the courses contact, forums, emails, exams and quizzes to students to download and interact.
While there is an extensive body of literature regarding how the implementations of LMS using Moodle as a platform improve students academically (Alan, 2011; Kaya, 2012); help lectures in organizing the learning martial (Kaya, 2012; Richardson et al., 2012; Tiantong & Teemuangsai, 2013; Vallejo, 2011); Alan, 2011); provide social interaction and communication between lectures and students (Liu, 2013; Paier, 2007; Thoms & Eryilmaz, 2014); allow plug-in to offer Second-life environment (Annetta, Folta, & Klesath, 2010; De Lucia, Francese, Passero, & Tortora, 2009; Dubas & Hill, 2013); the clear focus of the literature is on what Moodle offer.   Little is been known on why educational institutions use or migrate to Moodle and the process of.  Furthermore, distance learners' perception in IIUM perceived usability, usefulness and ease of use toward the use of LMS (Trayek & Hassan, 2013; Ustati & Hassan, 2013).  On the other hand, the students hope for more interactivity in order to communicate with other learner and engage more with the instructor.  In addition, Trayek & Hassan (2013) suggested in their study to upgrade and to customize the LMS to be suitable with the new Web 2.0 to allow innovative teaching and learning.  Therefore, this study is to show why IIUM migrate from LMS to Moodle and the technical process of developing and implementing the new LMS (iTa'leem).  Furthermore, to find if the migration accomplished the goal IIUM looking for.

Moodle

With the wide spread of distance learning, universities have to have a system to manage and promote e-learning.  Universities choose the technology that is appropriate for its own e-learning need and strategy taking some factors in consideration.  Moodle has been designed as a software package entailing services for educational purpose. It provides the users with access and community tools.  These facilitate the support and management of the main learning operation processes enlisting curricula and courses, learner access, enrolments and approvals, events and scheduling and completion and certification (Fernandez et al., 2011).  Ravanelli (2014) state that the main factors when choosing LMS are: "quality/expense ratio, quality and number of tools and environments available, frequency of updates, flexibility, customisation, and usability of the environment".   
Since Moodle is an open-source platform, Matei & Vrabie, (2013) used a cost-effectiveness analysis to compare two platforms of e-learning that support distance learning programs in the same university.  The study hypothesis started from the fact that open source software like Moodle is less expensive than the developed internally like Learning Management System (LMS), in spite that it does not fully meet the requirements of the university. The analysis covered the effectiveness of the distance education, and the costs required to implement them.  The university continued to use Moodle because the result shows little difference but it was not significant since it was necessary to purchase the server to operate the system and store information in Moodle, but it reduces the cost of hosting.
There are a strong preference by administrator, staff and students of some of Moodle's features.   For example, administrator has the rights to generate courses and appoint lectures.  Similarly, lectures can generate and manage their courses while adding students to the course. Administrator and lectures have the choice to select between various security levels like unlock key or protection with password for a certain part of the course (Paier, 2007).  Moodle is easy to use, easy-to-navigate, clean, simple design, users does not necessarily have to have a prior knowledge of programming or specialist technological skills to use it (Lawler, 2011; Mihailescu, 2009; Moore & Atkin, 2010; Tiantong & Teemuangsai, 2013; Vallejo, 2011).  Moreover, the compatible with most web browsers (Ambrosio, Striano, Freda, Fiorentino, & Aiello, 2013; Davoli et al., 2008; El-Seoud, El-Sofany, Taj-Eddin, Nosseir, & El-Khouly, 2013); the automated course/unit creation and auto-enrolment of students into the course/unit (Lawler, 2011).  Furthermore, easy access for users gives them the convenience of uploading and downloading files from any location, especially users from off campus (Lawler, 2011; Liu, 2013; Richardson et al., 2012).

One of the characters that Moodle environment has is simplicity.  It allows designer to use a variety of functions to perform operations to support their system (Mihailescu, 2009).  Moodle is constructed to allow a wide variety of plug-in modules; it is featured by a number of modules which depends on the need of the user (Bogdanov et al., 2012; Lai & Sanusi, 2013; Tiantong & Teemuangsai, 2013).  For example, it has features that allow it to organize from a large scale as of hundreds of thousands of students in a university to a hundred students in a small primary school (Lai & Sanusi, 2013).  The modules depend on three main personnel: administrator, lectures and students (Paier, 2007).  Some of these modules offered for learning tools like Communication tools with discussion boards and chat; assessment tools to create quizzes, upload assignments, reading materials and wikis; video and audio upload; last but not least, feedback to tracks performance level, post grades and allows instructor comments (Lai & Sanusi, 2013; Paier, 2007).  Furthermore, Survey, Voting, Journal and Poll are some of the features that Moodle offer. Students enjoy different possibilities depending on the module. For example, in a study using Second Life virtual environment, Moodle was used to set up to offer navigable multimedia contents and manages a collaborative sitting.  A Moodle plug-in was developed to manage and provide the multimedia contents through the QuickTimeTM player, and was easily integrate with the streaming server.  Furthermore, with the LMS features offered in the Second Life virtual environment, Moodle enhance integrating Second Life objects use (Annetta et al., 2010; Davoli et al., 2008; De Lucia et al., 2009; Dubas & Hill, 2013).  

AIM OF THE STUDY

The intention of this qualitative paper is to explore the biggest project in IIUM; the migration from LMS to the new LMS (iTa'leem) which used Moodle as a platform.  Furthermore, to find if the migration accomplished the goal IIUM looking for.  Additionally, to highlights the technical process of developing and implementing (iTa'leem).  The ISO-9126 Quality Model as a useful tool for evaluating software system is used as a guiding framework in order to cover the bases of Moodle software.  The investigation of this study is guided by three research questions:
1.     Why did IIUM migrate from the previous LMS?
2.     Why IIUM chose Moodle as a platform for the new LMS (iTa'leem)?
3.     Was the migration successful?

THEORETICAL FRAMEWORK

The ISO-9126 Quality Model is a useful tool to evaluate the quality of software system.  The model was developed in 1991 by the International Organization for Standardization (ISO) and refined in 2001 as cited by Abran, Khelifi, Suryn, & Seffah, (2003)  in (Chua & Dyson, 2004). The model was developed to provide a set of standards that would be recognized and respected internationally.   The original model defines six characteristics: Functionality, Usability, Reliability, Efficiency Maintainability, and Portability (see Figure 1); each characteristic has its sub-characteristics.  Table 1 shows the six characteristic and its sub-characteristics (Abran et al., 2003).

    Figure 1: ISO 1991 Model

The ISO 9126 model was used in this study because it covers the technical requirements and human interaction with the system.  Moreover, it is easy employ by non-specialist, not complicated like IEEE P1484.1 LTSA model, SCORM or IMS (Chua & Dyson, 2004).  In addition, this study focused on first three characteristics of ISO-9126 functionality, usability, and reliability.

4.    METHODOLOGY

The researchers used a qualitative approach to gain in-depth information to address the questions essential to the study.  A semi-structured interview was conducted by the researcher with one member of the iTa'leem project, an administration personal in the Centre for Professional Development (CPD) at IIUM.  The interview was conducted one time, face-to-face for about 55 minutes. The questions were asked in a relaxed fashion to the participants at her office. The interview was audio recorded with the permission of the interviewee. To care for the validity and the reliability of the transcription, one copy of the transcription is given to the informants for verification.  After analyzing the data, transcribing the interviews, reading the text and listening to the tapes a few times, the researcher had a holistic perspective of the migration project in IIUM.
