Make physics relatable to students. By using examples in your lessons that are contextual to the lives of the students, you give them a greater sense of connection to the subject matter. For example, trajectory problems can be given in the context of sports, while problems relating to velocity can be explained through amusement park rides.
Give interactive lessons. The students will want to test the formulas and theories they are reading about and solving in your class. By giving the students hands-on examples, they will make a greater connection with the subject matter.
Keep your activities short. Physics can be a daunting subject, so don't give your students a chance to be overwhelmed or bored in your class. Switch up what you are doing every 15 minutes or so to make sure that you are keeping their attention. Switching between activities and teaching moments will give students a change of pace that will keep them engaged.
Create connections between your lessons and subject matter in the student's other courses. Speak with other faculty members and find out what students are learning. This will give you a unique opportunity to integrate that information into your course and help students build connections between various subjects.
