Here are some examples to address barriers for mathematics' students: Provide open-book quizzes. During quizzes and tests completed individually, provide scheduled breaks so students can communicate with each other and their instructor in order to become 'unstuck' while working on complex equations and problem solving. For example, during tests, one mathematics instructor writes some of the complex equations on whiteboards around the room.During a ten-minute break, students have the option to approach a problem and talk through their thinking in order to progress to the next step in the activity if they are stuck. Allow for small group work. Use a computer program, such as software for creating drawings, to demonstrate lesson goals and objectives. Allow students to take a video of themselves solving a problem and talking through their thought processes. Provide a choice of mathematical problems for students to complete to demonstrate mastery of a learning objective. (UDL on Campus: UDL and Assessment, CC BY-SA 4.0)
