Paper-based vs computer-based exams in CS1
Vesa Lappalainen, Antti-Jussi Lakanen, Harri Högmander · 2016
In this study, we examine the "test mode effect" in CS1 exam using the Rainfall problem. The participants started working with pen and paper, after which they had access to a computer, and they could rework their solution with a help of a test suite developed by the authors. In the computer- based phase many students were able to fix the errors that they had committed during the paper-based phase. These errors included well-known corner cases, such as empty array or division by zero.
