LiveTest: An Open-Source OMR Testing Software
摘要
In education, the effortless analysis of test results is vital to teacher effectiveness. Instructors at all levels have relied on hardware-based OMR systems to meet this need. Although effective and requiring minimal instructor effort, this method imposes financial burdens. Costs begin immediately at the university level with the purchase and maintenance of the OMR scanner. Universities incur costs for purchasing and maintaining OMR scanners, while students must buy compatible answer sheets for each test. These expenses can be especially challenging for those with limited resources or immediate funding. This paper presents LiveTest, a highly customizable and configurable testing solution. It integrates Pictron to generate flexible answer sheets, which are graded using the dynamic OMRGrader module. Instructors can upload images of completed student answer sheets via any web browser to a predefined test for immediate grading. Results and analytics are updated in real-time, reflecting live changes as new submissions are received. The paper also details the processes of extracting, standardizing, interpreting, grading, and archiving the answer sheets.
