(In Class or Distance Learning) Demonstrations illustrating uniform motion and accelerated motion are used at appropriate times to elucidate this topic. Students are always encouraged to ask questions in class or in the LMS discussion board throughout the presentation. Distance Learning (In Class or Distance Learning) Using an audience response system, students are asked to answer conceptual questions on one dimensional motion (other examples free-body analysis, energy conservation etc.) to assess their learning and develop critical thinking skills. In the online modality this can be accomplished synchronously using polling software or asynchronously using a discussion board.
