<p>Hi Zenaida,</p> <p>Informative lectures take an extraordinary amount of time and dedication. The preparation alone is&nbsp;enormous if you are really doing the topic/lecture justice. It is important to be creative and presentation is key; using a variety of instructional methods is important and keeps the student engaged. It also helps to create an environment where you can adapt the teaching&nbsp;strategies with&nbsp;the individual&nbsp;student's learning styles.</p> <p>Sharon</p>
