Quizzes with multiple attempts
I think that as formative assessment, I will include multiple quizzes within each module. The students will see their incorrect responses immediately and the quizzes will allow multiple attempts so that students are getting feedback on their answers and getting the chance to learn from their mistakes. Students can begin the next topic when they have earned at least 80% on a quiz. I will also have larger-scale online quizzes/exams at the end of each module for summative assessment.
