Abstract
The ever increasing demand for quality education and the overwhelming increase in the population of students’ community turns out the traditional method of face-to-face (FTF) teaching to be an uphill task due to the shortage of qualified and experienced faculty members. This paves way for offering courses online, which is claimed to cater the above-mentioned demand through virtual classrooms. To verifythis claim, the course Data Structures was offered online as anexperiment at our College of Computer Science and Engineering. The course content modeled as multimedia document was developed using Macromedia Authorware 5.0 with integrated text, speech, & animations, which was delivered using a tool called WebCT. The pedagogical analysis (which includes interactivity, self-learning, flexibility, etc.) of this experiment has been presented in this paper. The study uses the data collected from survey conducted with the students and the faculty members involved in the online course.
Keywords: Face-to-Face, Online Education, Pedagogy.
1. Introduction
With the advent of the Internet, the very concept of
education has changed drastically. In developing countries
the number of students who want to do higher education is
1
increasing overwhelmingly and the universities would not be
able to cope if it does not adapt the e-learning process due
to the limitation in the number of qualified faculty
members. Nowadays almost all universities started offering
online courses or at least experimenting with it. The
motivation behind this is to verify the claim that online
education serves as a means to handle more number of
students with the existing resources.
1.1 Online Education in King Fahd University
King Fahd University decided to examine the outcome of
online courses during the year 2001 and College of Computer
Science was chosen as the sample piece for experimentation.
We, in the Information and Computer Science department of
the college decided to switch the FTF delivery of the course
“Data Structure and Algorithms (ICS202)” to online e-learning during
the first semester of the academic year 2001/2002. The
effectiveness and success of online course offering in many
ways depend on increased demand for student’s convenience,
including his/her time, pace and place of learning [4]. The
2
best evaluators of the online course offering are its
learners. In this paper, we present the case study about the
pedagogical analysis in offering the course ICS202 online at
our university. The kind of study reported in this paper is
necessary to evaluate certain factors like the effectiveness
of e-learning, changes in teacher/student interaction,
students’ convenience, collaboration among students,
improvement of student skills, flexibility of learning,
teaching load of the faculty members involved in e-learning
etc. This will also help us evaluate how good inline
learners our students are [2].To add strength to our
discussion, we would like to present how ICS202 course was
developed and delivered to the students. The rest of the
paper is structured as follows. Sections 2 and 3 outline the
development and delivery methods of the course Data Structures
respectively. Section 5 presents methodology of the survey,
Section 6 analyses the results of our case study and Section
7 concludes the case study with proper remarks.
2. Online Course Content Development
3
The development team for the online course Data Structures
consisted of 6 team members who jointly acted as subject
experts, instructional designers, graphic designers and
programmers. Thus the team can be viewed as multi-
disciplinary as advocated by the British Open University
[6]. The development tool was mainly Macromedia Authorware
as it is more suitable for the development of online lecture
slides. We identified the following processes for this
course development [1].
Preparation: In this phase, the development team was
formed and the proposal for the online project was
made.
Analysis and Scheduling: The foundations necessary to
realize the proposal made in preparation phase were
done in this phase. As a first step, the subject
experts developed an outline of the course coverage.
This was followed by a discussion to decide on an
authoring tool that can be used to develop the course
content for presentation to the e-learners. Finally an
4
action plan was developed to schedule the tasks
involved in realizing the e-learning in practice.
Course Design: The entire syllabus of ICS202 was
divided into 6 smaller modules of lecture units so that
the development of course content can be carried out
parallel by the team members. The role of the course
content developers is to identify examples, animations,
and the interactive questions for each lecture unit
they are working on.
Course Content Development: After the detailed design,
the actual content was developed. We learned from
experience that writing the narration transcript during
the content development could reduce significant
development time.
Web Content Development: The detailed course content,
the outcome of course content development, was
digitized by the implementers or the content developers
using the selected authoring tool. Our experience
revealed us that animations obtained by using the
authoring tool of choice are more convenient than using
5
external animation tools. The narration was recorded
using a voice expert or using the text to speech
software. As expected, our students are more
comfortable with the human voice rather than the voice
of text-to-speech software.
Testing and Evaluation: To validate the course content
and the expected perfection in the digitization, the
preview of the e-learning was conducted with team
members being the spectators. The unsatisfactory slides
in the presentation were mostly due to flaws in content
development or in digitization. In any case, the
implementation was modified to get the desired
performance.
Deployment: The last stage of the online course
development process was compiling all the course
contents and making it available to the students
through an appropriate course-delivering tool such as
WebCT.
The development cycle is shown in figure 1.
6
Figure 1. Online course development process.The course content was organized into forty lectures for
easy mapping to traditional FTF lectures. Each lecture
takes, on average, 35 minutes to complete.
3. Online Course Delivery
This course Data Structures was delivered in a blended
mode involving FTF and online delivery. The traditional
three weekly meeting was converted to single weekly meeting.
This weekly meeting was utilized for question-and-answer
session as well as for periodical assessments. The
laboratory component was however, conducted in a traditional
manner, with an instructor in charge.
7
The reason for this kind of blended method of online
delivery was to keep our online students interested,
involved, reducing their anxiety and increasing their
motivation. This is supported by NYUonline’s research which
shows that providing one hour FTF session for every 4 hours
of self paced study was a highly effective mix [7]. Moreover
the blended method combines the best features of various
learning styles, for example accessibility and multimedia of
the online learning with the best features of the classroom
interaction. Thomson [3] also shows us that the group that
received Blended Learning performed with 30% more accuracy
than the e-Learning alone group.
In order to provide an on-demand access to the online
material at any time and at any place, apart from the course
web server, students were given access to hard copies of the
screen dumps of the Authorware presentation. A CD-ROM is
also provided containing the compiled course material as
posted on the WebCT.
3.1. Online slide layout for the Data Structures course

Figure 2 shows the screen shot of the online slide of
the Data Structures Course. The slide shown is designed to
address the issues that are not feasible in the FTF delivery
mode. With this design of the online slides a student has
freedom to move across any section of the lecture unit in
case he wants to clarify something. This option is almost
impossible in the FTF delivery. The controls provided for
this purpose are:
1. ‘Top’ button to move to the first slide of the
lecture,
2. ‘Previous’ button to move to the previous slide of
the lecture, and
3. ‘Next’ button to move to the next slide.
Additionally, when the student is using the slides for
revising purpose, the option for disabling the narration
(mute) is provided. Another highlight of the online slide is
the pause button. This feature allows the student to have
enough thinking time before he continues to the next point.
Moreover this helps the students to compute any calculations
if presented in the slide before proceeding with the
9
narration. In this particular course, the option for
repeating each slide in the lecture is provided. But from
our experience we found that the students would be more
comfortable if a control is also provided for repeating the
specific bullet of the slide.

3.2. WebCT online course delivery tool
In our university, we use the tool WebCT to deliver the
course online to the students. A snapshot of the main page
of the tool is shown in Figure 3. The tool supports the
following features.
Utilization of streaming multimedia
10
Use of internet based communication technologies
(chat room, threaded discussion forums, etc)
Support for various online teaching styles
Support for conducting online quizzes
Support for automated grading

4. Pattern of Student/Teacher interaction in traditional
course versus online course
We observed a significant change in the Student/Teacher
interaction mode between FTF and online. The substantial
difference between the two media is in the pattern of
dialog. In FTF the teacher [T] asks a question (sometimes
preceded by a comment), and a student [S] responds. The
alternation of teacher and student is consistent as
11
illustrated in Figure 4. Each utterance is a direct response
tightly coupled to the immediate previous utterance. Each
speaker often talks directly to someone – students always
respond to the teacher, teacher often directing a cold-call
question, follow-up question, or feedback to a specific
student. The time gap between utterances is regular and
very short.
Figure 4. FTF delivery
Whereas in online offering of the course, the teacher
initiates discussion in the discussion forum of the online
delivery tool WebCT. A number of students respond, sometimes
simultaneously, and often with no reference to other student
responses. As the discussion keeps going, many students
might respond to a provocative comment by another student.
The teacher occasionally responds to student comments, but
12
mainly summarizes the discussion and lead transitions into
appropriate discussion areas. A point worth noting here is
that a number of student comments and several teacher
comments generated no explicit response. It is possible for
several discussion threads to run simultaneously. Several
students observed in a follow up survey had “no time” to
read other students’ comments before posting their own
comment, and others complained about duplicated postings.
The alternation of the response of teacher and student was
not consistent as illustrated in Figure 4 but changes as
shown in Figure 5.

5. Methodology of survey conducted
As discussed in the section 4, the activities of both
students and the faculty members changes considerably in
13
online course offering compared to that of FTF. To study the
impact of these changes both the students and the
instructors involved in the online offering were surveyed.
5.1 Details of the survey conducted with the students
The students’ survey questionnaire consists of four
major categories. The first category of questions addressed
the students’ convenience in online education, the second
set of questions traps the flexibility of students’ learning
in online education, the third group of questions addressed
the students’ collaboration with other students and their
instructors and the last category of questions examined the
development of students’ skills in online education. A total
of 64 students who took this ICS202 course online were
surveyed. The details of these questions are stated below.
5.1.1 Students’ convenience in online education:
1. Online offering has helped me to have self paced
learning.
2. Online course offering helps me to make my schedule
flexible.
14
3. Online course offering has on-demand access to learning
material.
5.1.2 Students’ flexibility in online education:
1. Online course offering assists me in choosing the
topics of study at my own interests.
2. Online course offering assists me to study the course
at my preferred location.
5.1.3 Students’ collaboration in online education:
1. My interactions with other students have increased due
to online offering of this course.
2. My interaction with my instructor has increased due to
online offering of this course.
5.1.4 Development of students’ skills in online education:
1. I manage my time properly for this online course.
2. My time management skill has increased by taking this
course online.
3. My self learning capability has increased by taking
this course online.
4. My retention rate has improved by taking this online
course.

5.2 Details of the survey conducted with the Instructors
In this part of the study, our focus was to compare the
amount of time it takes to teach an online offering of a
course vs. the FTF offering of the same course. The
instructors who took part in this study had already taught
this course “ICS202” in traditional FTF mode before they
switched to the online mode of teaching. This makes these
instructors an appropriate sample for the subject of our
study.
Instructional time of any instructor in higher education can
be categorized as follows [5].
1. Administration of the course
2. Discussion [Online discussion via WebCT].
3. E-mail [Email to/from students]
4. Grading [ online/offline grading]
5. FTF meetings
6. Preparation [Preparing for the class, modifying the
course material, etc.]
7. Phone calls with students
16
8. Technology [technical problems with the specific online
tool or learning about the online environment]
A questionnaire was prepared considering the most
appropriate points in the above-mentioned categories which
suited our environment and the details of questions are as
follows.
1. Does online offering need more administration than FTF
offering?
2. Do you have more email discussion with students in
online offering than FTF offering?
3. Do you take more time for grading in online offering
than the FTF offering?
4. Is your preparation time for the course more in online
offering than in FTF offering?
5. Do you have more online discussion with the students in
online offering than FTF offering?
6. Do you have more phone calls with the student in online
offering than FTF offering?
17
Each of the above mentioned questions including the
questions in the students’ survey had five options [1 to 5]
as shown in Table 1.

6.1 Student feedback analysis
First we will present the analysis of the students’
feedback. Although, we had eleven questions on the
questionnaire we show only the survey result of one question
in each category of the questionnaire for the sake of
briefness. The rest of the analysis is summarized in the

Chart 4Charts 1 to 4. Students’ Feedback
It is obvious from chart 1 that the online course
offering has improved students’ self-learning capability
compared to Face-to-face offering. This is due to the habit
that is nurtured in the minds of the students through the
mode of online course delivery that he learns for himself
and instructors are there to guide them through. For this
the students involved in the online courses have to be
instructor independent to a certain extent. From our
19
experience we found that students find it very difficult to
adapt to this mode of instructor-independent learning at the
transitional phase to online delivery. But later they got
accustomed to the online delivery and got huge benefit out
of it. One more factor which improves the students’ self-
learning in online learning is that the students can learn
the course at their own pace which is not feasible in the
FTF delivery mode. Chart 4 confirms the above-mentioned
point about the self paced learning.
Chart 2 clearly displays the flexibility of taking the
course by the students from any desired location of their
choice. They don’t have to be physically present in the
class room in order to listen to a lecture. Students learn
best in a friendly, comfortable, socially interactive, and
diverse environment. This kind of learning environment truly
supports the self-esteem of the student, which is obtained
only by online education.
Chart 3 shows another important factor, which is the
interaction among students. Interaction among students has
increased drastically in online offering. This is due to the
20
fact that students use the online discussion forum to
clarify their doubts on the subject. Online discussion forum
provides room even for the introvert students to post
question on the discussion forum. It is not always the
instructor who answers the question on the discussion forum,
other students who know the answer to a specific question
can also respond. The role of the instructor in the forum is
to act as a moderator. Most of the times the instructor,
start the discussion by posting questions on the subject and
allows the students to interact. The instructor after giving
enough time for the discussion summarizes the discussion
including the correct answer for the question he posted
earlier.
In the FTF offering there is a chance that some
students miss the answers given by the teacher in the
classroom session. But in the case of online delivery mode
the answers provided by the teacher on the discussion forum
are recorded and the students have the choice of viewing it
at any time. There is also option for searching the
21
discussion archives on a specific topic. This is an added
advantage in the online offering over FTF.
A short summary of the student feedback including the
result of the other questions in the questionnaire is given
in Table 2.
Online learning is self paced, and thus, very convenient
for students. The course fits the students schedule which enables
greater number of students to take the course. On demand access to the course material, both from the
web server and the CD-ROMs is very convenient for the
students. Online education is self directed by the fact that
students can choose any section of the course content
while studying. Online education reduces the travel time and the
associated cost by taking the course at their preferred
location. Online education fosters more student interaction and
collaboration. Online education also fosters self learning capability of
students. Time management skill and retention rate of students have
also improved in online education.

Chart 8Charts 5 to 8. Faculty Feedback
Out of 6 questions in the faculty survey questionnaire
only 4 of them are shown above in the charts for the sake of
briefness again. Considering the feedback from faculty
members who were involved in teaching online courses, we
observed from chart 5 that the administrative work remains
almost same irrespective of the nature of teaching
23
methodology. Chart 6 shows that e-mail discussion with the
students has reduced considerably. This point is supported
again by chart 8 that the faculty member does most of the
discussion with the students through online discussion forum
provided by the content delivery tool like WebCT. Chart 7
implies that the grading time has considerably decreased in
online offering. The reason behind this is that the quizzes
conducted online with the help of the content delivery tool,
WebCT has the automated grading facility. So the faculty
members are left only with grading the major exams.
Considering all the feedback cumulatively from the faculty
members, we can infer that online offering reduces slightly
the load on the faculty members, which is not in favor of
the claim that more students can be handled by the
university with the same amount of resources. The reason
behind this is that faculty members spend considerable
amount of time in discussion forums answering the students’
questions. Table 3 summarizes the feedback from the faculty
members.
Administration of the online course takes almost the same
24
time as the FTF offering.
Email discussion with the students has reduced
considerably.
Grading time of online offering is less than the FTF
offering.
Preparation time is almost the same in online offering as
well as the FTF offering.
Online discussion through the online discussion forum is
more in online offering than the FTF offering.
Table 3. Summary of the faculty feedback
7. Conclusion
Traditional teaching is now being slowly complemented
with online teaching. The results shown in this paper are
the outcome of the survey conducted for the course Data
Structures (ICS202) offered in the College of Computer Science and
Engineering at our university. Thorough study has been made on
the results and a comparative analysis between delivering a
course online and FTF was done. After careful analysis we
have found that delivering a course online in blended mode
with one FTF meeting with the instructor per week has proved
25
to be very effective in higher education over the
traditional FTF classroom session. As far as the load of the
faculty members teaching online courses are concerned only a
small percentage of it has been reduced. Our opinion is that
these results would not be in favor of online delivery if
the courses were offered without any meeting with the
instructor. From our experience and thorough analysis of the
results of the case study we conclude that any course can be
better delivered online with one FTF meeting with the
instructor, provided the students who are involved in the
online courses are trained to be instructor-independent at
least to a certain extent.
