2  Background  The problem  Dimensions of the problem  Major issues/conflicting requirements  IT to the rescue May 24, 2010LINC 2010

3 Virtual University of Pakistan (VU) delivers education through innovative uses of IT VU conducts its courses under a formal semester system with a defined academic calendar Video lectures are delivered through: – free-to-air television on VU’s TV channels – Data DVDs – Youtube: May 24, 2010LINC 2010

4  Student-teacher interaction is through a comprehensive Learning Management System ◦  Examinations: ◦ Formal proctored examinations ◦ Twice a semester (midterm and finals) ◦ Conducted at dedicated exam centers (f2f) May 24, 2010LINC 2010

5  Large student body ◦ Nearly 60,000 students and growing!  Scattered all over the country ◦ 95 cities and more…  Admissions twice a year ◦ Average annual intake is ~25,000 students  160+ courses offered every semester May 24, 2010LINC 2010

6 Full time students – Normal course load – Mostly as per scheme of studies Working students – Partial course load – Variety of course distributions – Limited study times/exam days/hours Stragglers and certificate students – Can take any course in any semester May 24, 2010LINC 2010

7 How can the University conduct mid and final term examinations in a secure, convenient, time-limited and efficient manner? May 24, 2010LINC 2010

8  How to create a datesheet (exam schedule) that satisfies all students  How to ensure: ◦ Secure distribution of question papers ◦ Sanctity of examinations across the country ◦ Efficient and secure collection of answer sheets ◦ Grading within an acceptable time frame May 24, 2010LINC 2010

9  Exam centers must run at capacity if exams are to be conducted in a reasonable amount of time (number of days) but  Working students prefer evening hours or weekends for exams  Full time students prefer morning times, weekdays for their papers May 24, 2010LINC 2010

10  Commuting students prefer mid-day times!  Students prefer to have gaps between papers Management Issues:  Mismatch in exam start timings can lead to examination leaks across the country  Ensuring proper invigilation across all centers is a nightmare May 24, 2010LINC 2010

11 Allow students flexibility in choosing their examination dates/times on a first-come first-served basis and run centers at full capacity to minimize the total duration of the exams May 24, 2010LINC 2010

12  Allowing students to create their own individual datesheets on a first come first served basis: ◦ Can only work if students receive distinct question papers ◦ Can be done by creating a question bank and automating the process! May 24, 2010LINC 2010

13  Question Bank  Student created individual datesheets  Distinct paper generation  Encryption and security  Conduct  Grading  Result May 24, 2010LINC 2010

14  Includes MCQs and Essay type questions  Questions identified by ◦ Syllabus topic / Lecture number ◦ Difficulty level ◦ Type of skill being assessed ◦ Etc.  New questions added on daily basis  Old/overused questions retired after each examination May 24, 2010LINC 2010

15  Determine: ◦ the total number of (Students*Subjects) ◦ the capacity of exam centers (computer seats) And hence  Determine and define grid of: ◦ Exam Centers ◦ Exam days (including weekends) ◦ Exam times (multiple sessions in a day) May 24, 2010LINC 2010

20  Academic staffs provides paper parameterspaper parameters  System generates required number of distinct question papers May 24, 2010LINC 2010

21  All e-papers for a center are collected  Dispatched by / transferred to a CD and sent via courier  Cannot be opened before date/time and then only with passwords which are NOT provided beforehand  Questions are doubly encrypted anyway and cannot be read except through software May 24, 2010LINC 2010

22  Exam software and encrypted data are loaded onto exam center servers using file password  Session password is sent to the invigilator by /SMS on exam day 5-10 minutes before exam  Data for only a single session is unlocked  Students log in and are given their question paper according to their datesheet May 24, 2010LINC 2010

23  At end of each day, an exam file containing student answers is sent back to VU by from each center  Contains data for all sessions for the day  Files are uploaded into the grading system and MCQs marked automatically May 24, 2010LINC 2010

24  Student attempts are collected and sorted by question  All attempts for one question are given to a single tutor for grading  Grading rubric/reference is provided by QB  Ensures anonymity and uniformity May 24, 2010LINC 2010
