Abstract

We propose here the ultimate solution of an electronics learning system which is built on

the open source web platform named Joomla and Moodle, integrating the leading e-commerce

module in the cyber civilization called VirtueMart. Our website is the mixture of the current

digitalized trend and the temporary modern scientific technology that illustrate the most

advanced of web developing achievements and the freedom using of computerized products like

open source. We apply those fantastic applications in the education system in universities,

especially in the subject Information Technology as well as other subjects in our education

system.


1. Introduction

Nowadays, Basic Informatics, or Information Technology in general, is the compulsory

subject in almost universities in Viet Nam. This subject aims at providing students with the most

basic knowledge about information technology. Via practicing, students are trained for skills

such as using the Windows operating system, text editor with Microsoft Word, spreadsheet

processing with Microsoft Excel, doing presentations with Microsoft PowerPoint, using Internet

and e-mail, even learning valuable professional course like CCNA, MCSA, OCP, etc. Up to now,

teaching and learning this subject are delivered by direct communication between lecturers and

students, following the Basic Computing Curriculum.

Actually, there is a fact when following the smooth and fast and highly developing stream of

scientific and technology of the world, original education method face-to-face is really old and

becomes ancient. Online-education as known as E-learning is the key to the success in every

education system where most developed countries apply. In our country, it is new, however, and

incredible. Imagine sitting on the computer comfortably at home, click the pointer, open the site

and attend the lecture from your teacher who is standing in the class, it is a miracle. There is

another fact that once everything is computerized and digitalized like information technology,

cyber civilization tend to use open source resources more than proprietary software, because it is

free, convenient and especially, it “says in your way”. The final fact after those two is that, when

you use computer often, it will become great if you can sit at home and click and buy a

motorbike without going outside your house, even with payment methods. E-commerce is what-

we-call here and it is in the initial step but growing.

Originating from those three theories above, our project really makes a breath through in the

technology and offers you an electronic supported the remote learning and teaching system

called “e-learning”, which is running on the open source web platform including Joomla, Moodle

and VirtueMart – the leading e-commerce system in the whole world .

Here goes What, Why and How our project starts…


2. Why should we choose this method: Electronics education system

2.1 Evolution of Vietnamese online environment

The Internet has registered the fastest growth among all means of communications known in

the communications industry history – faster even then television and telephony. For example we

know that, only in Europe, the number of households who have Internet access at home has

doubled each year since 1997, while worldwide, the Internet user population has registered a

spectacular and continuous growth. Also, the communication on the World Wide Web is very

fast, allowing instant transfer and manipulation of large databases, text files, images, multimedia

files all over the world. As a result, the consumers can purchase and obtain any digital product

(software, e-books, video presentations, video-conference, etc.) instantly from the Web.

Vietnam is not an exception from this global trend. Statistically speaking, the number of

Romanian Internet users exceeded 6 million in 2006. According to the statistics of the results

from the site http://internetworldstats.com which collects network management agencies in many

countries, it shows that growth rates of the number of Internet users in Vietnam in the period

2000-2009 is 10,882%, which is much higher than the same group of countries in relative

markets like China (1,500%), Indonesia (1,150%) ... At present, the rate of net users in Vietnam

is about 26%, the Philippines, Thailand.

In urban areas about 50% of the populations access the internet, in Hanoi and TP HCM, the rate

is even higher. Cimigo survey results show that two thirds of respondents access the network

every day and the time spent surfing on average per day is 2 hours and 20 minutes. Moreover,

Royal Pingdom said, with 24.3 million Internet users out of 89.6 million people, Vietnam ranked

20 in the list of 20 countries in the world which has the highest Internet users.

Once the Internet accounts continue to rapidly grow; Vietnamese objective area is to develop the

knowledge-based economy, by promoting research, innovation and by accelerating the

development of the information society. It is well known that services, including services in

education, cannot exist, or cannot be developed, without rapid and secure ways to exchange

information. On the other perspective, modern electronic public services (e-governance, e-

education and e-health) should be developed and made more efficient.


2.2 Electronics educating concept in Vietnam

According to a Moodle study, one of the companies that provide educational services via the

Internet, the Government spent, this year, more than 10 percent of the training budget especially

or e-learning, which means double compared to last year. "The biggest interest for such kind of

services, comes from companies with many employees and, especially, from those who have

employees in the territory (in different regions, locations). Banks and telecommunications

companies are the first who use e-learning. This is because through computer-base courses are

transmitted information related to internal procedures, to work organization and protection that is

mainly the huge amount of knowledge that an employee must have, but whose assimilation is

generally pretty boring. Using checked methods for maintaining attention such information goes

to a very large number of employees with cost that are not very high”. It is very easy to realize

that this segment, the Vietnamese Ministry sector, is an important generator of demand for e-

learning.

Traditional universities have been more than slow in integrating ICT in their teaching and

learning. The reasons for this are linked to strategic and organizational change issues and not

even in the first place to technological or budgetary issues. Successful e-learning indeed requires

new organizational and pedagogical models.

This conflicts with the historical model which shaped the culture of our traditional universities.

As long as ICT is seen as a tool to support teaching, the interest of the top decision makers in

universities for an e-quality label will be not very high; especially since universities are already

involved in many other internal and external quality processes, which they find highly

bureaucratic. Quality e-learning requires institutional change, continuous introspection and

innovation as well as critical awareness of weaknesses which have to be overcome.

Decision makers in universities have to be involved in discussions and convinced about the real

possibilities of ICT. This should be done in a non-technical way and in the context of their own

cultural context taking into account their current preoccupations. It is necessary to overcome the

gap between the converted and the non-believers. If this process is neglected, bottom up ICT

initiatives in teaching and learning will not blossom.


Furthermore, in order to make ICT truly accepted as an important factor that could help

traditional universities in transforming its organization, including teaching and learning

processes, it is necessary to have the support of organizations like Ministry of Education and

Training, in charge of preserving quality in higher education.

Universities are considered to play an important role in innovation for the knowledge society.

However, in their own organizations change often is elusive or takes place in an incremental

way, most often therefore outside the core of the university in the “developmental or

entrepreneurial periphery”.

This can be illustrated by the fact that despite since several decades there has been an optimistic

discourse going on about the transformative power of ICT; most of our universities are still stuck

in old paradigms especially as far as teaching and learning are concerned. No wonder many ICT

initiatives have failed. The internet bubble of early 2000 strengthened the view of the pessimists

– for the wrong reasons. The transformative power of ICT has still not been fully grasped. ICT is

by many mainly seen as an operational tool which can enhance specific functions of the

university such as data collection (Enterprise Resources Systems), the administration or

operational aspects of teaching (e.g. schedules, slide distribution). ICT matters are left to the

Chief Information Officer (CIO) or to the audiovisual department for teaching and learning

support.

The rise of the knowledge society and its context brought new demands facing the higher

education sector such as the need for lifelong learning, which is becoming part of the mission of

traditional universities. Tensions exist between on the one hand being an organization which

protects the traditional academic values, a professor centered view and a focus on research and

on the other hand being a modern constructivist organization with a focus on learning in which

the relationship with the student is central.

Among the core values of traditional universities are the importance of research and the quality

of teaching and learning profiting from a local community. Many universities are led with the

research rankings in mind. Most of these universities also find the physical campus extremely

important and investments in expanding campuses continue.


Skepticism about the use of ICT for teaching and learning is still high in many traditional

universities. Many reasons can be found, on which we cannot expand in this note. Traditional

universities do not realize that fully embedding technology in their strategy will enable them to

build an organization, centered on learning and the student relationship, to create a community

experience on the web and to organize research in a different way. The recent trends 2010 report

from the Vietnam National University shows that there is still a long way to go towards student

centered learning.

However, The World economy is entering a knowledge economy period. Therefore, improving

the effectiveness of quality education and training is a vital factor in determining the existence

and development of each country, companies, families and individuals. Furthermore, the learning

is not only compact bundle in high school, undergraduate college that is life. E-learning is an

effective solution for solving this problem. Broad sense, E-learning is a term used to describe the

learning and training based on information technology and communication, especially

information technology.

According to modern views, E-learning is the delivery of learning content using modern

electronic tools like computers, satellite networks, the Internet, Intranet, ... in which learning

content can be obtained from websites, CDs, videos, audio ... through a computer or TV;

teachers and learners can communicate with each other online forms such as e-mail, online

discussion (chat), forum (forum), video conferencing ...

At around 2002 and earlier, the research literature, and survey about E-learning in Vietnam is not

much. In the two years 2003-2004, the study of E-learning in Vietnam was much more interested

by many units. Recent conferences and seminars on information technology and education have

been much mentioned on E-learning and the ability to apply the training environment in

Vietnam, such as improving the quality of workshop training VNU in 2000, higher education

conference in 2001 and the recent scientific conference on the first national Research,

Development and Application of information and communication technology ICT / RDA 2 /

2003, Second National Conference Study on Research, Development and Application of

information technology and communication ICT / RDA 9 / 2004, and scientific conference


"Research and development E-learning" by the Vietnam National University (VNU ) and the

Faculty of Information Technology (Hanoi University of Technology) jointly held the first in

March 2005 under the scientific conference on E-learning was first held in Vietnam.

Universities in Vietnam have made the initial research and development E-learning. Some units

were initially deployed software training and support for the results: College of Technology -

VNU, Institute of Information Technology - VNU, Hanoi University of Technology, VNU-

HCMC, City Academy, and Telecommunications. Recently, Informatics Center Ministry of

Education and Training has implemented E-learning portal to provide systematic way of E-

learning information in the world and in Vietnam. In addition, some software companies in

Vietnam have launched several products to support learning and training. Although these

products are not yet large products, packaged completely but initially contributing to the

development of E-learning in Vietnam.

This shows the situation of research and application of this type of training is interested in

Vietnam.

3. Body

3.1 Technology:

3.1.1 E-learning system:

E-Learning is defined as all forms of electronic supported learning and teaching, which are

procedural in character and aim to effect the construction of knowledge with reference to

individual experience, practice and knowledge of the learner. Information and communication

systems, whether networked or not, serve as specific media to implement the learning process.

It is the systems for managing training and educational records, to software for distributing

courses over the Internet with features for online collaboration. Student self-service (e.g., self-

registration on instructor-led training), training workflow (e.g., user notification, manager

approval, wait-list management), the provision of on-line learning (e.g., Computer-Based

Training, read & understand), on-line assessment, management of continuous professional

education (CPE), collaborative learning (e.g., application sharing, discussion threads), and

training resource management (e.g., instructors, facilities, equipment), are dimensions to “e-

learning”.

E-learning is essentially the computer and network enabled transfer of skills and knowledge. E-

learning refers to using electronic applications and processes to learn. E-learning applications

and processes include Web-based learning, computer-based learning, virtual classrooms and

digital collaboration. Content is delivered via the Internet, intranet/extranet, audio or video tape,

satellite TV, and CD-ROM. It can be self paced or instructor led and includes media in the form

of text, image, animation, streaming video and audio.

E-learning is replacing the century’s old model of teaching and learning, which focuses on an

instructor standing in front of a classroom lecturing to students. This model no longer fits the

way people want to learn today, because of technological world in which they live. With the

rapid advances in technology and Internet tools, the traditional model is fading away to

accommodate today’s learners.


Traditional teaching is being replaced by an evolving e-learning model which uses online

technology to allow people to learn anytime and anywhere. This model includes work place

training, the delivery of just-in-time information, college courses, continuing education units,

and guidance from experts. The advantages of e-learning include:

• Actively engaging students in the learning of process, as opposed to being passive

learners.

• Supporting interactivity between a student and instructor, along with fellow students.

• Taking advantage of social media and learning management systems to deliver course

materials.

• Supporting digital natives (typically 18 – 27 year olds) in their continuing education

efforts through applications of web 2.0 technologies as a means to sustain their learning.

E-learning is changing the way people learn. There are three main reasons why e-learning

continues its rapid growth, include:

• The economy continues to struggle and more companies are cutting costs by using e-

learning technologies to train employees. These cost savings measures are becoming the

norm, instead of the exception.

• Students want to make better use of their time and money; this is why they continue to

take advantage of e-learning opportunities.

• More companies want to establish a reputation of being eco-friendly, to this end they are

supporting more use of e-learning programs to sustain their green initiatives.

E – Learning began at just about the same time that a computer was developed that was practical

for personal use. Up to now, it has been determined that in comparison to traditional ways of

learning in the classroom, on television or on radio, e-learning methods create a superior

performance. By this new studying method, students can learn anytime, anywhere and can

choose the content, curriculum based on their ability to receive knowledge or interests. There are

also many terms that you can consider when thinking of an e – learning website such as Cost

savings, universities may have to spend a lot of money for buying computers, projectors or many

more things while with e – learning, students can practice on their own with available resources


on the website; Learning quality: E-learning can be more flexible (learning at a convenient time,

learning spread over weeks, etc) and can even provide a higher quality of learning. Many

students learn better and retain the learning much longer when permitted to learn at their own

pace. And many students find that learning a little each day can be more effective than classroom

approach.

A key attribute of information and communications technology is its ability to enable flexible

access to information and resources. Flexible access refers to access and use of information and

resources at a time, place and pace that are suitable and convenient to individual learners rather

than the teacher and/or the educational organization. It aimed to allow distance learners, who

were generally adult learners in full or part-time employment to be able to study at a time, place,

and pace that suited their convenience. The goal of distance education was to free these learners

from the constraints of conventional residential educational settings. They would not be required

to live or attend lectures in locations away from where they may be living and working. The

printed distance study materials, which each distance learner received, would carry the core

subject matter content they would need including all their learning activities and assessment

tasks. Students would be required to complete these tasks, submit their assignments and take

their examinations within a set time frame. While these printed study materials allowed distance

learners a great deal of freedom from time, place and pace of study, it had its limitations. For one

thing, non-printed subject matter content and simulations etc. could not be easily represented in

print form.

Access to information and communications technology changed all that as it offered a range of

possibilities for capturing and delivering all types of subject matter content to learners and

teachers in distributed educational settings. This meant access to subject matter content and

learning resources via networked information and communications technologies across a range

of settings such as conventional classrooms, workplaces, homes, and various forms of

community centers. This is becoming increasingly affordable and palatable with a wide range of

software applications and computer conferencing technologies for collaborative inquiry among

students and asynchronous discussion. These applications enable learners and teachers to engage

in synchronous as well as asynchronous interaction across space, time, and pace.


Information and communications technology also enables the capture and storage of information

of various types including print, audio, and video. Networked information and communications

technologies enable access to this content in a manner that is not possible within the spatial and

temporal constraints of conventional educational settings such as the classroom or the print mode

In the context of this distributed setting, users have access to a wide variety of educational

resources in a format that is amenable to individual approaches to learning, and accessible at a

time, place and pace that is convenient to them. Typically, these educational resources could

include hyper-linked material, incorporating text, pictures, graphics, animation, multimedia

elements such as videos and simulations and also links to electronic databases, search engines,

and online libraries.


3.1.2 Why Joomla:

Joomla (CMS – Content Management System): an open source solution that is freely

available to everyone, which enables users to build Web sites and powerful online applications.

Figure 1: Joomla – CMS

• Free - The fact that this program has been made free to use by consumers, is an

astonishing fact. Those who offer the average Internet user and web developers this

program for no cost, are those who make life on the Web a cinch.

• Plug-in - They are customizable extensions available for you to use, depending on what

your site needs are overall. There are over 4,000 different types of extensions in

the directory, ready to be added to your site.

• Components - They are tools available to the web developer team for the website,

components will allow for more added customization for the site, as well. Site builders

can use them to backup the website or create better search engines.

• Modules - They are small applications that will add greater functionality and bring richer

content to your site. A module may add a PayPal button on your site for payments, bring

applications updates from Twitter, or bring Flash content to your site.

• Joomla Community - You won’t feel all alone while using this program or feel that you

don’t have support, because there are many Joomla forum communities all over the web.


You can keep up with the newest in features or be the first to know about bugs, that users

are experiencing, if you join a forum community.

• Open - Joomla! is an ‘open’ framework covered under a GNU/GPL (General Public

License) and is therefore freely available for anyone to use, modify and implement. The

client is therefore not locked into using a proprietary CMS under a restricted license basis

or locked into one particular development/implementation company’s services.

Ultimately if you're not happy with our knowledge and skills regarding Joomla!, or (god-

forbid) we cease to exist, a simple Google search will return the results of other

companies and/or individuals around the world offering similar services.

• Convenient - Joomla allows in-house management of all website content, depending of

course on the capabilities of the people using it. By definition a content management

system is designed to separate front-end presentation of content (i.e. design/template)

from the content itself (text, images, etc.), which is more than likely stored in a database

and 'served' as requested. When content is served to the browser, the template takes care

of where the content presents and how it is formatted.

• Security: Joomla! is secure. Joomla! started out much like the Linux operating system,

which is another open-source project, and has grown to become the most installed, secure

and implemented web server on the planet! Joomla's core team of developers are as

skilled as any other developers and, as a general rule, the open source development

community tends to seek recognition from their ability to find and fix bugs and security

threats rather than gain notoriety from being able to hack them.

• Joomla! is therefore comparatively cost effective, secure and simple to manage!! This is

really important for some kinds of semi-professional administrators in universities to

manage the site with little IT knowledge.


3.1.3 Why Moodle:

Moodle (LMS – Learning Management System): a free learning management system that

enables you to create powerful, flexible, and engaging online learning experiences, which may

include sequential series of web pages, images, animations, and a online quiz, email, bulletin

board communication among the teachers and students… (Moodle 1.9 E – Learning Course

Management, a complete guide to successful learning using Moodle 1.9)

Figure 2: Moodle - LMS

Key Benefits to the Institute

• Saves Institute paper and toner costs

• Saves Institute answer sheet costs

• Utilizes Institute's computers and intranet

Key Benefits to Students

• Saves students pencil costs

• Students become familiar with standard teaching software that is in wide use

• at schools internationally and via distance learning systems on the Web.

• Gives students immediate, detailed wash back

o They see their results immediately. They don't have to wait.

o Their grades are centralized and accessible to them (during class) and easy for

them to keep track of.


o Computer tests are easy to repeat. A student can take a learning quiz twice in a

row and you can give him the higher score, or you can give him an adaptive quiz

in which he can respond more than once to a question, but is penalized for any

incorrect response. These can be used for learning.

o Each and every student gets individualized attention from the teacher through the

Moodle quizzes, which provide opportunities for the student to respond more

than once to, say, a grammar question, and provide immediate feedback to the

student's response(s), so:

§ Instead of one teacher taking 25 students through a ten-item grammar

exercise in class, with each student doing one sentence completion or fill-

in-the-blank, in a Moodle quiz 25 students can respond to 25 such items

each, and each gets immediate feedback.

o They see the correct answers to items they got wrong immediately

§ This enables them to perform a cognitive comparison within minutes of

making an error or mistake. Published research has shown that when a

student makes a cognitive comparison – between a target form and the

incorrect form that he has provided – this better enables the student to

learn and retain the target form.

Key Benefits to Instructors

• No photocopying

• No answer sheets

• Don't have to carry the test around

• No need for the test marking device

• Grading is automated

• Washback is automated. (No need to go over the test. Each student does this individually

after completing it.)

• Can shuffle test items and/or responses in items. No need to have two versions of a test

because each student's test is different from his neighbors (theoretically; I haven't actually


gone around the room and proved this for each and every terminal, but I've observed that

the sequences are indeed different.)

• Can manage time test. Students know when it's over and my experience has been that

they don't ask for extra time.

• Can analyze students' responses to see which items produced most incorrect responses.

This could be useful for planning lessons to review material.


3.1.4 Why VirtueMart:

Figure 3: VirtueMart

Virtuemart is the leading e-commerce system for use with the Joomla Content Management

System. More than 1.5 Million downloads so far and according to one estimate approximately

250,000 active online installations.

Virtuemart is Open Source software which means it is undergoing constant development by the

very people that use it. It is secure, feature rich and easy to use. Using VirtueMart is just an

optional function when user wants to access some professional course like CCNA, MCSA, OCP,

etc... Those are valuable and certificated courses, therefore students to pay money for purchase

the courses.


3.1.5 Joomdle

Joomdle consists of a series of extensions for Moodle and Joomla to integrate them. SSO

from Joomla to Moodle. Show Moodle contents in Joomla pages. That is the technology we

use in this project to integrate those two kinds of open source into each other.

3.1.6 Why Open Source:

Open Source's proponents often claim that it offers significant benefits when compared to

typical commercial products. Commercial products typically favor visible features (giving

marketing advantage) over harder-to measure qualities such as stability, security and similar

less glamorous attributes. As shorthand, we shall describe this phenomenon as quality vs

features.

Many of the qualities that are claimed for Open Source are exactly those that are wanted by

those who have to use or deploy software, yet run almost directly counter to the commercial

needs of typical software development businesses, where a continuous revenue stream

(usually through the mechanism of upgrades or high-priced support) is needed.

Our government also recommends using Open Source because its huge advantages:

reliability, stability, auditability, cost, flexibility and freedom and things else. That’s why we

use the open source web base as Joomla and Moodle, also include Course of open source like

Ubuntu, Firefox, even Joomla and Moodle course inside.

3.2.2 Moodle E-Learning


3.2.3 VirtueMart E-Commerce


4. Conclusion:

Needless to say, e – learning has made a great impact on education globally and Vietnam in

particular. Our University has witnessed the efficiency of applying online training with Moodle

online websites of Faculty of Information Technology, Foundation Studies Department and so

on. Moodle itself is an excellent tool for supplement training and educating, now, in our project,

which combines Moodle and Joomla, the leading open sources web platform and VirtueMart,

other leading e-commerce system, we believe that the result will be more than the expectation.

On the side of students, they will benefit from our website through the reference resources they

can download from it, which is very helpful for those who are not much good at searching for

materials. Besides, the ability to reach online source anytime, anywhere is absolutely cool. The

reason is studying Computing needs a lot of time spent on own discovering and own practicing.

At class, students only have two hours for studying plus practicing. That amount of time is not

enough for improving the Computing skills.

On the side of Hanoi University and Basic Informatics Faculty, the website will be the right hand

for improving education quality while reducing the teaching and training effort as well as the

infrastructure cost. When student can download and study at home, then lecturers can focus on

the important points on class only and tell student to study others at home. One more thing is the

assignment generating system that these management systems offer; lecturers do not have to

spend much time on evaluating students’ exercises.

We hope that the website will open the new horizon and make the breakthrough in the learning

and teaching system in universities to build the brand new era of electronic education in the

future.
