How can learning be best effectuated by a teacher/trainer (be specific/give examples)?

A teacher can effectuate learning best by simply being there for the students. "Being there" would include providing unique learning opportunities, constantly evaluating the students, providing feedback, and guiding the students to their end goal. For example, I teach multimedia classes and often have certain projects for my students to complete. If I am going to be there for my students, I need to provide them with a unique project that will allow them the opportunity to use prior knowledge to discover new information or to develop a new skill. As they are working on this project, I need to evaluate the progress of each student and provide them with feedback where necessary. By doing so, hopefully I can successfully guide them to the end goal in mind. If I omit any of the above mentioned elements of my "being there, " my students may not be able to connect the beginning with the end and could easily get off course from getting to that goal.
