  2. 2. Final Year Defense Outline • Introduction • Aim and Objectives • Hypothesis • Research Questions • Literature Reviews • Proposed model • Design & Development • Testing and Evaluation • Result Analysis • Performance Analysis • Conclusion • Future works • References 2
  3. 3. Final Year Defense 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. 3
  4. 4. Final Year Defense 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 4
  5. 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. 5 Hypothesis
  6. 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 6
  7. 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? 7
  8. 8. Final Year Defense 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. 8
  9. 9. Final Year Defense 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. 9
  10. 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. 10

  18. 18. Final Year Defense 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. 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. 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. 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% 21
  22. 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 22

  25. 25. Final Year Defense 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. 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 26
