<p>My wife teaches library science at the elementary school level and she had a graduate student visit her class to observe.&nbsp; The student told my wife that watching her interact with her&nbsp;class in her library&nbsp;was more valuable than all of her studies at the university.&nbsp; You cannot beat the real world as a classroom.&nbsp; So we are challenged to bring the real world into our teaching environment as well as we can through discussion of our collective experiences and demonstration exercises.&nbsp; I also take my students on field trips and try to bring in quest lecturers.</p>
