An Exploratory Case Study of the Use of Video Digitizing Technology to Detect Answer-Copying on a Paper-and-Pencil Multiple-Choice Test
In educational testing, answer-copying is considered a behaviour that poses threats to the validity of test scores interpretations, which is a concern when interpreting the test results for the purpose of making changes to curriculum and educational policies. Answer copying involves at least two examinees, one being the source and the other the copier. While different methods have been developed to detect answer-copying using statistical indices, researchers have not yet examined the use of video digitizing technology via a kinematic sanalysis of the data to detect answer-copying during test taking situations. The purpose of this case study was to explore the use of video digitizing technology to detectanswer-copying by measuring examinees’ response time, displacement and velocity from item to item on a test. A sample of two university students volunteered to demonstrate the benefits and challenges of using video digitizing technology to detect answer-copying. While this is a small scale demonstration, the outcome of this study may shed light on whether or not the use of video digitizing technology provide evidence of feasibility and some preliminary reliability in the detection of answer copying.The lesson learned from this study can inform the direction of a future program of research.
