Choice of teaching style depends on the nature of topic(s) and the characteristics of the learners. Either or both of the traditional or modern styles may be suitable for the instructional process of a particular topic to realize the set objective(s).
I believe there is no harm in combining the two methods. Both traditional and modern methods can be used to accommodate different learning styles of our learners. What is important is that each learner should learn.
Close learning of the text of 'great' literature is actually essential. I have taught Sons and Lovers (D. H. Lawrence) and realised that the subtleties of the novel can easily be lost by too rapid readings-and therefore its brilliance. Interactive methods or the use of film and power-point would not bring out Lawrence's amazing sensitivity and approach to psychology.
I learned how to write Spanish in Barcelona thanks to my last term's Argentinian teacher. We were 40 students and maybe 30 nationalities in class. Most of them had economical-business purposes. I was the only one that wanted to write in Spanish. So Marta decided the whole term will be around a Garcia Marquez's book of short stories. And she taught me all what she knew about writing in Spanish. It was so fascinating and instructive that nobody of the other 38 students noticed a thing, but a Chinese illegal immigrant women that went through hell and was the most hard-working student. "She does the course just for you. We're lucky".
