Chapter 1 Introduction
1.1 Preface
The development from traditional learning to electronic and mobile learning is to
achieve better understanding, comprehension and acquisition. Tutors use different
conventional methods in the traditional learning as boards, maps and graphs and also
different developed methods in the electronic learning such as multimedia and internet to
make student gets better knowledge and experience. But do these methods guarantee the
achievement of the learning goal? In order to check students learning and performance
tutors always test them by different ways; quizzes midterm exams or questions during the
class.
Tutors like to discuss students’ results after the exam or the quiz. They may need
to solve students’ problems or give them advices. The bad results in the exam may reveal
the use of wrong methods by the tutor. So tutors need a way to test students and to
analyze the result to find the main cause of student’s weakness and to adapt the learning
material to fit student’s needs. Many researches and projects proposed electronic
solutions such as web-based environments to support the learning systems in many
disciplines and at all levels of education system [2], [4]. Others suggested mobile-based
solutions which use different technologies such as SMS or WAP [6]. The following
paragraphs discuss the development of the electronic learning and mobile learning
systems.
E-learning is an electronic delivery method. Early forms included CD-ROMs and
knowledge pools on the Internet, where users could access information and work through
it at their own pace. The term E-learning refers nowadays to online courses and Learning
Management Systems (LMS). Many systems have proved a success in this field to
manage and deliver information. Learning Management System helps tutors to manage
course material and distribute assignments [30]. But these systems are still a single user
and support little interactivity and stimulation for the student [10]. New E-learning
researches have focused on developing the interaction among students. Another style of
Web based learning was designed to support brain storming and generate creative
thinking [29].
A new term has been emerged which is called Mobile learning (M-learning).
M-learning is to enhance the E-learning by providing new ways for information delivery,
supporting mobility and developing students’ interaction and collaboration. The
development of mobile devices such as mobile phones and Personal Digital Assistants
(PDAs) has emerged a variety of services are now available for PDAs, tablet PCs and
mobile phones including mobile tourist guides and navigation systems [1] . Mobile
devices can use different communication technologies to deliver the information. Internet,
WAP, MMS and SMS can be used to carry different types of information and offer
several services. Brendan Riordan showed that students prefer to use SMS functions to
help them in their education as library recalls, revision tips and assessments marks [24]
[28]. Many researches showed different uses of mobile phones especially SMS in
Education [26] [27]. Some business companies have already started to produce
M-Learning kits as SMS-Quiz author and Pocket PC author [25]. Mobile phones can be
used also for class management and LMS [32] [33] and it is preferred over other mobile
devices [34].
New researches have highlighted the importance of collaboration and interaction
within e-learning. Researchers as Preece (2000); Hamburg, Lindecke, and ten Thij (2003);
Salmon (2002) and Thurmond and Wambach (2004) amongst others have done
researches on LMSs, and as a result online forums and discussion boards have become an
invaluable resource in LMSs [10]. The collaborative systems allow students to
communicate with their peers and tutors thus empowering them to socialize and learn
together online. Mobile phones are also used to support student’s collaboration and
interaction [35] [36].
Teresa Monahan (2006) [10] showed another approach to enhance students’
interaction. Through the use of technologies such as Virtual Reality (VR) and instant
communication, students can be more visually aware of their classmates and can
converse in real-time with them. They can also receive immediate feedback from their
tutors and gain a sense of being present in the same place as their peers despite their
remote physical locations. These shared virtual environments also facilitate simultaneous
viewing of learning materials by the whole class and allow them to actively partake in
group discussions about the learning content at the same time. VR has been very popular
and successful in other areas including entertainment and urban planning. It has also been
extensively used within manufacturing industries and military bodies [11]. In addition,
the benefits of 3D graphics for education have been explored. Many 3D resources have
already been developed in this area. 3D models are very useful to familiarize students
with features of different shapes and objects, and can be particularly useful in teaching
younger students. Many games have been developed using 3D images that the user must
interact with in order to learn a certain lesson. Interactive models increase a user’s
interest and make learning more fun. 3D animations can be used to teach students
different procedures and mechanisms for carrying out specific tasks.
Our research discusses an integrated web based learning system with mobile phone
based system using SMS. The system was designed to provide an administrative tool,
develop students’ interaction, comprehension and understanding. The following sections
will show our motivations and the methodologies used to solve some learning problems.
The next chapters will discuss the system’s analysis, requirements, architecture, design,
Evolution and experimental results.
