I was surprised in a faculty meeting today to hear that most prefer TurnItIn and reported discrepancies in percentages when the same paper is submitted to both Safe Assign and TurnItIn. Just this week I learned from another colleague that iThenticate is better because it doesn't run a paper against student's previous papers which can alter percentages. But I have Safe Assign to work with so I want to get the most out of it. Any suggestions? Thanks!
