IMPACT OF ENCRYPTED MULTIPLE CHOICE EXAM ON STUDENT SUCCESS

Abstract

Due to the rapid advancement of technology, the science of cryptography increasingly gained importance. Basically, the encryption algorithms used to encrypt the message or data. This work is motivated from ÖSYM (National University Entrance Exam of Turkey in 2011). The main aim of this study is to analyse the impact of encrypted multiple choice exam on students’ success in Computer I course which is offered to Faculty of Law at Cyprus International University. Therefore, the study uses the results of an encrypted and non-encrypted multiple choice exam used in Computer I course. Encrypted multiple choice exam involves individual question sheets for each student having their own answer keys. For this reason, the original exam questions were arranged differently for each student. Thus, a separate answer key is created for each one of the students. While there were 150 students who took the course in fall 2011-2012, there was no assigned priority to any of the questions. In the implementation, the generated one-time pads (keys) are permutations of n numbers where n was the number of questions. This paper aims to compare effect of encrypted exam with non-encrypted exam results on different groups of students’ success, using descriptive and inferential statistics. It is aimed to measure whether or not there is a correlation between the encrypted and non-encrypted exam results.
