With the digital valuation system (DVS) of answer scripts set to be implemented in all 193 colleges of Visvesvaraya Technological University (VTU) by this year-end, the varsity sought to address fears among students and lecturers about the arrangement at a meeting on Wednesday, 4th April. The DVS, under which all answer scripts are bar-coded, scanned at high speed and uploaded on the varsity server, has been introduced in 30 colleges on a pilot basis.
Hand in hand with DVS, the varsity is also implementing the question paper delivery system (QPDS), designed to eliminate the leak syndrome bugging the about-to-conclude II PU exam system. VTU registrar (evaluation) Krishna Murthy affirmed that at no stage will DVS be completely handed over to a third party and every phase will be monitored by VTU officials. "The varsity evaluates around 15 lakh answer scripts every semester and the amount of effort and cost is huge in case of physical valuation. DVS will resolve these problems. Moreover, the revaluation process will be very easy and economical as answer scripts can be mailed to the student's mail id," he pointed out. The discussion also took into consideration apprehensions about the system. "Many are concerned about the possibility of tampering with answer sheets as the stitched portions are cut for scanning. To negate the chances of tampering, we can look at options like either scanning the sheets without chopping off the stitched part or identifying each paper of the script through further use of technology," said Dr. Rajnikant, former academic senate member, VTU. Other problems like visibility of answer scripts during scanning were also discussed at the meeting. "Although students have been given clear instructions to use black pen, many still opt for blue ink or pencils at times, for sketches. The solution to this problem lies in utilizing only 80% of the scanner's life and the printing quality will improve," said Rajnikanth. The discussion sought to throw light on the mechanism of question paper delivery system (QPDS). "It is highly secure and the most important feature that ensures security is that question sheets are uploaded only 45 minutes before commencement of the examination. Every college and session will have a secret key generated by the server and the printing process at colleges will be monitored by the VTU registrar," said Krishna Murthy.
How it works?
Each answer script is given a bar code and scanned by high-speed high-resolution machines that can scan up to 800 scripts in eight hours. The scanned copies are then unloaded on to the VTU server. The authorised valuator will log in to the system using the user name and password assigned to him/her. Only 10 answer scripts will be assigned at one time. On day one, a valuator will correct 30 scripts, the next day 40 and from day three onwards, 50 scripts daily. The marks are entered in the system and calculated automatically.
