As shown in Figure 1, twincode offers a source code editor where the students concurrently develop the solution to a proposed exercise and can validate it against several test cases. It also offers a chat window, where they can collaborate to solve the exercise. Note that a gendered avatar is displayed for the student in the experimental group only (right), but not for the one in the control group (left).
