The teacher in the previous video used robotics technology to demonstrate how mathematics and a graphing calculator could be used to solve a real problem. Effective use of technology involves considering the concepts, skills, and issues you expect students to learn, selecting technologies to offer related opportunities for student learning, and implementing strategies for best use.
Technology can be a great addition to the classroom. It is most successful when used to improve student learning and help students reach their goals. You may get ideas about using different technologies from a variety of sources, including colleagues who've had success or a particular resource made available by your college. The range of technologies is great and increases every day. Ultimately it will be up to you to evaluate the potential effectiveness of a particular technology for your course and your students.
