1. Paolo’s planning style would be the most similar to what I did with my groups when I tought Spanish to foreigners. Variety of activities is important because most of the students had been working all the day. I combined the different skills ( reading, listening, grammar and vocabulary) in different lessons, though I try to do speaking practice with them in every lesson.
2. In planning a unit of work balance of activities and skills practice is one of the most important to make sure the students get to practice the different aspects of the language. Cohesive lessons (usually basing the lesson on a topic ) also helps them relate the different activities they do.
3.I started with a general idea of what will "fit", because it's very important for them.
4. Probably this teacher needs somebody to helps him the way to use different skills and what's the way to program a lesson.
