Nazanin, These strategies are so important in the development of the knowledge and expertise of students. I use a lot of case studies for the reasons you mention in my own courses. The more I can help students make a connection between the content I am teaching and the applications they are making the greater the retention of the content is going to be. By being a practicing professional you have examples and stories to share each time you interact with your students so your information is current and relevant at all times. Keep up the good work.
