Formative assessment tests can be done in 4 ways to evaluate student learning and teaching effectiveness: 1) Entry and exit slips at the start and end of class using tools like Google Forms to see what students remember and found interesting. 2) Low-stakes quizzes and polls using apps like Quizlet and Socrative to get instant feedback on student understanding. 3) Self-assessment tests where students use rubrics or participation cards to indicate their progress in different colors on a whiteboard. 4) Peer assessment through group discussions and private tests on apps like Seesaw to understand each student's learning from their peers' perspectives.
