powerpoint
I do utilize powerpoint presentations as another medium to eliminate tedium. Utilizing such a medium engages visual and auditory learning styles as the graphics engage the sight and my highlighting the impotant points engages the auditory senses.
Juanito,
I think one important key you mentioned is preparation of the slides. Good, useful PPT slides really do take time to prepare, edit, and format. Oftentimes publisher slides are not altogether useful as I find they are mostly outlines of the chapter from the textbook. I think if we want the student to read, they can use the book, not a summarized PPT slide. I find making my slides pertinent and succinct takes time, effort, and thoughtful consideration to be meaningful. I regard PPT as a tool, and tools have a purpose. No tool serves every purpose, so being selective is important, as is having the "tool" fully operational when it's time to be used.

Likewise, we do use powerpoint presentations in our lectures. A good powerpoint presentation must have very good content or substance, have visually appealing , well organized, easily readable slides and most importantly presented in a very interesting manner. This can be accomplised by good preparation. The presentor must be able to connect to the audience. You know that you have accomplished these when the students are engaged and are all enthusiastically asking questions.
Thanks,
