Introduction
• An Interactive web based virtual classroom can be defined as
an online teaching and learning portal unlike physical
classroom.
• Here the term ‘Interactive’ that defines face to face
communication which is commonly seen in the physical
classroom.
• Analyzing several research and related works, this paper
shows an effective way for designing a web based virtual
classroom.

Aim and Objectives
• Although many research have been done to explore the
effective way of virtual education, but very few of them have
been conducted in the context of Bangladesh.
• The main goal of this research is -
– to explore an effective way that can play a vital role in virtual
education particularly in the context of Bangladesh
– To provide an effective and easy method for teaching and learning
– To furnish the modern education among the students of rural area
– To reduce the distances between teacher and student
– To reduce the waste of time

5. Final Year Defense
• Virtual Classroom might perform equally or better in
some specific situation compared to the physical
classroom.
• The learning consequences might be more effective
and result oriented if it does as flipped classroom.

Hypothesis

6. Final Year Defense
Hypothesis (cont’d)
• It is imagined that, if some tools might be integrated with the
classroom then it could be more effective for teaching and
learning.
– A paint tool
– A graphics tablet

7. Final Year Defense
Research Questions
• How to explore the concept of a virtual classroom where
teacher and student can take part interactively in teaching
and learning ?
• How to make it more effective mostly in the context of
Bangladesh?
• How can the distance learners be benefited using this virtual
classroom?
• How can the modern education be spread to the each
student of pastoral area?

Literature Reviews
An extensive research has been done in the area of virtual
education, Some of them are illustrated here-
•A large publishing company of technological magazines and
news (Comjagat.com) has deployed a web based virtual
classroom that deals with live classes by video streaming
lectures.
•Jago Foundation has started Jago online school in several
villages in Bangladesh. The online classes are conducted by video
conferencing tools using Grameenphon 3G network where a
teacher from a city can conduct classes for the village students.

Literature Reviews(cont’d)
• An online teaching and learning portal Coursea is a profit
educational organization founded by computer science professors
Andrew Ng and Daphne Koller from Stanford University that deals
with massive open online courses (MOOC). Generally works with
cooperation of different Universities to make some of their courses
available in online classroom also many engineering other different
courses are available. Here the live classes are conducted by video
streaming lectures.

10. Final Year Defense
Literature Reviews(cont’d)
• Udemy.com (2010) is a platform or marketplace for online learning.
Unlike academic MOOC programs driven by traditional collegiate
coursework, Udemy provides tools which enable users to create a
course, promote it and earn money from student tuition charges. It
provides the facility of Video streaming class including audio and
video conversations.

Testing and Evaluation
• To test and evaluate the system one test has been
performed –
– Effectiveness testing of teaching and learning
– The test is performed based on a measurement scheme
18

19. Final Year Defense
Testing and Evaluation (cont’d)
Measurement Scheme:
•The measurement scheme has been designed based on five
criteria –
– Understanding Subject and content
– Understanding the classroom and lectures
– Virtual Interactions and discussion
– Attending online quizzes
– Learning
19

20. Final Year Defense
Result Analysis
• Effectiveness measurement in the area of learning
– There are five parameters. Each parameter has 1 point and five questions. Each question
carries 0.2 points. Therefore the calculation is -
– 1 parameter = (5 question) x 0.2 = 1
– (5 parameters) x 1 = 5
– Effectiveness measurement in the area of learning holds 5 points.
• Effectiveness measurement in the area of teaching
– There are total 10 questions. Each question carries 0.5 points. Therefore the calculation
is -
– (10 question x 0.5) = 5
– Effectiveness measurement in the area of teaching holds 5 points.
20

21. Final Year Defense
Result Analysis (cont’d)
• The average effectiveness measurement calculation is -
– (Effectiveness point in the area of learning + Effectiveness point in the area of teaching)
/ 2
– We assume the both points are 3.6 and 4.1 respectively. The calculation is
– The effectiveness point is - (3.6 + 4.1)/2 = 3.85
• Now converting it to percentage
– The maximum point is 5. So each point carries 20% .
– 0.1 = 2%
– 0.2 = 4%
– 1 = 20%
– Therefore 3.85 = 70.7%

22. Final Year Defense
Performance Analysis
• The Effectiveness testing result is described in two
sections –
– Effectiveness testing of learning
– Effectiveness testing of teaching
The results are discussed in the next section

Conclusion
• Virtual Classroom is a web application that allows users an effective
environment of teaching and learning. Both Teachers and Students can be
benefitted in training and learning by this application.
• Classroom environment is user friendly as to navigate easily to find the
resources and class lectures
• Hope this will be a better solution in the field of learning and teaching
for present and future generation.
25

26. Final Year Defense
Future work
• Interface design will be updated
• More features and functionalities will be added
• Reliability of the application should be increased
• The application will be responsive as to be compatible to any
device
